Posted on by

Phase Ib study expected to initiate in H2 2024

Previously reported Phase I results showed MOv18 IgE to be safe and well tolerated, with evidence of anti-tumour activity

LONDON–(BUSINESS WIRE)–Epsilogen, a global leader in the development of immunoglobulin E (IgE) antibodies to treat cancer, today announces that the Clinical Trial Application for the Phase Ib trial of MOv18 IgE has been approved by the UK Medicines and Healthcare products Regulatory Agency (MHRA).

The Phase Ib study is expected to initiate later in 2024 and will evaluate the efficacy of MOv18 IgE in patients with platinum-resistant ovarian cancer (PROC).

Dr Tim Wilson, Chief Executive Officer of Epsilogen, said: “This CTA is another significant milestone for Epsilogen and the clinical development of MOv18 IgE. We look forward to progressing MOv18 IgE into a Phase Ib efficacy study later this year as we continue to demonstrate the potential of IgE antibodies as a new, differentiated class of cancer treatments.”

About MOv18 IgE

MOv18 IgE is an immunoglobulin E (IgE) antibody targeting the folate receptor alpha (FR alpha) antigen. FR alpha is present on a variety of cancers including ovarian, endometrial, lung and triple negative breast cancer. Epsilogen has successfully completed a Phase I safety study of MOv18 IgE in PROC patients. The results of the study, published in Nature Communications, found MOv18 IgE to be safe and well tolerated, with evidence of anti-tumour activity observed. Epsilogen, alongside its partner Lonza, also announced the successful completion of large-scale Good Manufacturing Practice (GMP) manufacturing of MOv18 IgE earlier this year.

About the Phase Ib study

The Phase Ib study is designed to confirm the safety and tolerability of MOv18 IgE and demonstrate efficacy in PROC. Following the dose escalation, an expansion cohort will be recruited to make a preliminary assessment of the anti-tumour activity of MOv18 IgE at a selected dose. In addition, delay to disease progression will be assessed along with a number of translational elements to generate further understanding of MOv18 IgE in the study population.

About Epsilogen Ltd

Epsilogen is a global leader in the development of immunoglobulin E (IgE) antibodies to treat cancer. IgE’s natural function is to provide immunological defence against certain parasites. This functionality makes it an ideal treatment of solid tumours due to its strong potency, enhanced tumour access and long tissue half-life.

Epsilogen’s lead product candidate, MOv18 IgE, is the first therapeutic IgE antibody to enter the clinic and encouraging data from a completed Phase I trial demonstrated MOv18 IgE to be safe and well tolerated with early signs of clinical activity. Epsilogen has recently successfully completed large scale GMP manufacture of MOv18 IgE (the first time this has been achieved for an IgE antibody) and will initiate a Phase Ib trial in platinum-resistant ovarian cancer patients later this year. The company is also developing a pipeline of IgE therapies in oncology as well as proprietary platforms including IgE bispecifics and unique IgE/IgG combination antibody molecules (IgEGs) with enhanced functionality.

Oculis Announces Positive Topline Results of Phase 2b RELIEF Trial with Licaminlimab, Designed to Transform the Treatment Paradigm of Dry Eye Disease with a Precision Medicine Strategy

Posted on by

ZUG, Switzerland, June 10, 2024 (GLOBE NEWSWIRE) —

  • Improvements in multiple sign efficacy endpoints were observed in full population and with predictive and more pronounced effects in the TNFR1 genetic biomarker population as identified in prior successful Phase 2 symptoms trial
  • Rapid treatment effect on corneal inflammation was observed in TNFR1 genetic biomarker patients as early as Day 15 and was statistically significant at final efficacy visit on Day 43
  • Licaminlimab was well tolerated similar to vehicle
  • Company plans to finalize Phase 3 development plans following an End-of-Phase 2 (EoP2) meeting with the U.S. Food and Drug Administration (FDA)
  • An investor and analyst webcast will be held today at 8:30am US Eastern Time

Oculis Holding AG (Nasdaq: OCS) (“Oculis”), a global biopharmaceutical company purposefully driven to save sight and improve eye care, today announced positive topline results from its Phase 2b RELIEF trial with licaminlimab, a novel anti-TNFα biologic eye drop with an established dual anti-inflammatory and anti-apoptotic mechanism of action in patients with dry eye disease (DED).

The Phase 2b RELIEF trial is a multi-center, randomized, double-masked, vehicle-controlled trial evaluating the efficacy and safety of licaminlimab in subjects with signs of DED (NCT05896670). The trial also evaluated the efficacy and safety of licaminlimab in a subpopulation of subjects with a TNFR1-related genotype as prespecified in the protocol. One hundred and twenty-two (122) patients were randomized 1:1 to either licaminlimab (n=62) or vehicle (n=60) across 4 sites for a 6-week treatment period and a 2-week follow up. A total of 23 patients carried a specific TNFR1-related genotype. Patients were evaluated for efficacy endpoints at baseline, Day 15 and Day 43. The prespecified investigational efficacy measures in this trial included multiple signs of DED that are accepted by the FDA as efficacy endpoints.

Phase 2b RELIEF trial showed positive effects on multiple signs of DED

  • For the full trial population (n=122):
    • Treatment effect favoring licaminlimab was observed in multiple sign endpoints including fluorescein staining in the total cornea, inferior corneal, central corneal and nasal conjunctival regions, and in the Schirmer’s test.
  • For the subpopulation of patients with the TNFR1 genetic biomarker (n=23):
    • Treatment effect favoring licaminlimab was observed in multiple sign endpoints including fluorescein staining in the total cornea, inferior corneal, central corneal, nasal conjunctival, total conjunctival and total ocular surface regions, in the Schirmer’s test, and in conjunctival redness.
    • Rapid and favorable treatment effect in favor of licaminlimab on corneal inflammation was observed as early as Day 15 that was significant at Day 43, as measured by the difference in mean change from baseline versus vehicle for inferior corneal fluorescein staining score: -0.59 (CI: -1.165, -0.017). The treatment effect also increased over time. See attached Figure.
    • Licaminlimab was well tolerated. The incidence of ocular TEAEs in the study eye was 11.5% in the licaminlimab group and 10.2% in the vehicle group. TEAEs in the fellow eye were similar to the study eye. All ocular TEAEs were mild and transient, and there were no serious ocular adverse events observed with licaminlimab in the study. Drop comfort was also evaluated and was similar to artificial tears.

Riad Sherif, MD, Chief Executive Officer of Oculis, commented: “We are pleased that we achieved all of our objectives for the trial, and extremely encouraged to see licaminlimab’s profound results with a precision medicine approach which has the potential to transform the way we develop drugs and treat patients in ophthalmology. With this and prior positive results on signs and symptoms, we look forward to discussing these encouraging data with the FDA and advancing this program into Phase 3.”

Eric Donnenfeld, M.D., Clinical Professor of Ophthalmology at New York University and Chair of Oculis’ Cornea Scientific Advisory Board, added: “The precision medicine approach with licaminlimab could be a groundbreaking paradigm shift in ophthalmology and the treatment of DED. The current approach of ‘trial and error’ and our inability to predict response for this highly heterogenous population leads to a low level of patient satisfaction. To my knowledge, Licaminlimab is the first dry eye disease medication to demonstrate in a clinical trial a predictive treatment effect in patients with a common genetic biomarker to potentially solve this problem.”

Christophe Baudouin, M.D., Ph.D., Professor of Ophthalmology and Chairman of Ophthalmology III at Quinze-vingts National Ophthalmology Hospital, Paris, and member of Oculis Scientific Advisory Board, added: “I am very excited to see that licaminlimab, with its dual anti-inflammatory and anti-apoptotic mechanism of action, targets the origin of DED and has the potential to be truly disease modifying as shown by improvements in several clinical signs of DED, including corneal staining.”

The Company is planning to conduct an end-of-Phase 2 meeting with the FDA to discuss the registrational path for licaminlimab in DED and finalize the Phase 3 development plan.

Analyst and investor call
The Oculis management team will host an analyst and investor call today at 8:30 am US Eastern Time, to review the trial results.

Interested parties may participate in the call via the following webcast here.

A replay of the webcast and accompanying slides will be available for 90 days following the event through the “Events and Presentations” page of the “Investors and Media” section of the company’s website.

About Dry Eye Disease (DED)
DED is a common condition estimated to impact nearly 40 million people in 2023 in the US alone1. It is a multifactorial disease in which ocular surface inflammation plays a central role in sustaining the pathological state2,3. It usually affects both eyes and patients may experience a stinging, burning or scratchy sensation. In addition, some patients experience sensitivity to light, eye redness, difficulty wearing contact lenses, difficulty with nighttime driving, and blurred vision which can greatly affect their quality of life.

Of the approximately 20 million patients who are diagnosed with DED in the U.S., about half or 10 million are considered to have moderate to severe disease1. However, only 13% receive prescription treatment, primarily with an anti-inflammatory medications1. Despite currently available treatments, with 87% of chronic patients still unsatisfied4 highlighting the tremendous unmet need remaining in this underserved patient population. Furthermore, given the heterogenicity of the DED patient population, there is a need for more personalized treatment approaches to improve outcomes for patients.

About licaminlimab (OCS-02)
Licaminlimab is an anti-TNFα eye drop candidate developed with a single chain antibody fragment (scFv) technology specifically designed to treat ocular inflammatory diseases. The dual anti-inflammatory and anti-necrotic mechanism of action of TNF-α inhibition has been well-established in inflammatory disorders where the systemic use of TNF-α inhibitors has led to marked improvements in the disease management and treatment outcomes. In multiple Phase 2 trials, licaminlimab has shown positive effects on treating both the signs and symptoms of DED and has been well tolerated. In addition, a genetic biomarker was identified which showed a clear correlation between this variant in the TNFR1 gene and improved response to licaminlimab.

Licaminlimab is an investigational drug and has not received regulatory approval for commercial use in any country. For more information, please visit: www.oculis.com

Tiziana Life Sciences Announces Six-Month Qualitative Improvement in Neuroimaging in 80% of Multiple Sclerosis Patients Receiving Intranasal Foralumab

Posted on by
  • Qualitative improvements in PET imaging seen in 80% of non-active Secondary Progressive Multiple Sclerosis (na-SPMS) Expanded Access patients receiving intranasal foralumab for at least 6-months.
  • FDA Allowance for an additional 20 Patients to be enrolled in the intranasal foralumab Multiple Sclerosis Expanded Access Program will allow further data collection and analysis.
  • Applied for FDA Orphan Drug Designation of foralumab for na-SPMS

NEW YORK, June 06, 2024 (GLOBE NEWSWIRE) — Tiziana Life Sciences, Ltd. (Nasdaq: TLSA) (“Tiziana” or the “Company”), a biotechnology company developing breakthrough immunomodulation therapies via novel routes of drug delivery, today announced the qualitative results for all 10 non-active Secondary Progressive Multiple Sclerosis (na-SPMS) patients enrolled in the intermediate-size patient population Expanded Access (EA) Program receiving foralumab for at least six months.

Tarun Singhal, M.B.B.S., M.D., Director of the PET Imaging Program in Neurologic Diseases, associate neurologist and nuclear medicine physician at Brigham and Women’s Hospital, a founding member of Mass General Brigham Healthcare System, and Associate Professor of Neurology at Harvard Medical School, commented, “Based on currently available data from the latest cohort of four Expanded Access patients, three out of the four subjects had findings that suggest a qualitative reduction in the microglial PET signal over a period of six months of treatment with nasal foralumab. When combined with my assessment of the first six Expanded Access patients at six months, eight of the ten suggest a qualitative reduction in microglial PET signal. Further studies are needed to confirm these findings using additional cases and quantitative approaches.”

Gabriele Cerrone, Chairman, acting CEO, and founder of Tiziana Life Sciences, added, “I am thrilled that 80% of the na-SPMS patients who received intranasal foralumab treatment for at least 6-months have a qualitative reduction of microglial activity as confirmed in these latest PET images. I am also greatly appreciative of Dr. Singhal’s research and look forward to the additional quantitative analysis of the data. With the allowance of an additional 20 patients in the EA program, the application for Orphan Drug Designation for na-SPMS, and the ongoing Phase 2a trial, Tiziana is rapidly progressing its intranasal foralumab program in multiple sclerosis.”

About Foralumab

Activated T cells play an important role in the inflammatory process. Foralumab, the only fully human anti-CD3 monoclonal antibody (mAb), binds to the T cell receptor and dampens inflammation by modulating T cell function, thereby suppressing effector features in multiple immune cell subsets. This effect has been demonstrated in patients with COVID and with multiple sclerosis, as well as in healthy normal subjects. The non-active SPMS intranasal foralumab Phase 2 trial (NCT06292923) began screening patients in November of 2023. Immunomodulation by nasal anti-CD3 mAb represents a novel avenue for treatment of neuroinflammatory and neurodegenerative human diseases.[1],[2]

About Tiziana Life Sciences

Tiziana Life Sciences is a clinical-stage biopharmaceutical company developing breakthrough therapies using transformational drug delivery technologies to enable alternative routes of immunotherapy. Tiziana’s innovative nasal approach has the potential to provide an improvement in efficacy as well as safety and tolerability compared to intravenous (IV) delivery. Tiziana’s lead candidate, intranasal foralumab, which is the only fully human anti-CD3 mAb, has demonstrated a favorable safety profile and clinical response in patients in studies to date. Tiziana’s technology for alternative routes of immunotherapy has been patented with several applications pending and is expected to allow for broad pipeline applications.

ExeVir Bio Announces Exceptional Virus Neutralization Potency of its Variant-proof XVR013m Antibody Against the SARS-CoV-2 Variant JN.1

Posted on by

Developed to provide protection for millions of immunocompromised and elderly individuals who are most vulnerable to COVID-19

GHENT, Belgium, June 04, 2024 (GLOBE NEWSWIRE) — ExeVir Bio, a biotech company developing robust heavy chain-only antibody therapies for broad protection against infectious diseases, today announced new data demonstrating that its antibodies are exceptionally potent in neutralizing the SARS-CoV-2 variant JN.1, the parental strain of the currently most dominantly circulating variants worldwide.

ExeVir’s COVID-19 program focuses on addressing the high unmet medical need to protect and treat immunocompromised and elderly individuals that account for respectively 4% and 10% of the global population. Despite the availability of effective vaccines, the immunocompromised and elderly remain at a higher risk for severe COVID-19 as they are often not able to elicit an adequate immune response to vaccination and therefore would strongly benefit from additional protection in the form of antibody therapeutics.

ExeVir’s variant-proof lead clinical candidate XVR013m is a heavy chain-only antibody that targets a unique membrane-proximal epitope in the S2 subunit of the spike protein. This binding region remains completely unmutated across all variants of concern, variants of interest and variants under monitoring that have circulated to date. XVR013m demonstrates exceptional neutralization potency against JN.1, the parental strain of the currently most dominantly circulating variants worldwide, with an IC50 of 2.8 ng/mL in a pseudovirus neutralization assay, unchanged compared to all previously tested variants. The activity against new circulating variants under monitoring is continually being tested.

ExeVir is currently gearing up to start the clinical development of the variant-proof XVR013m in 2025 as a solution for the prevention of COVID-19 in the target populations of immunocompromised and elderly individuals.

Jeanne Bolger, interim CEO of ExeVir, said: “COVID-19 is here to stay and is still the most important respiratory infectious disease causing substantially more hospitalizations and deaths compared to influenza and RSV. Today, no real seasonality is observed for COVID-19, in sharp contrast to influenza and RSV. Our antibody XVR013m is differentiated by targeting a unique and highly conserved epitope in the S2 subunit of the SARS-CoV-2 spike protein that makes it virtually variant-proof.”

Viki Bockstal, CSO of ExeVir, said: “XVR013m not only demonstrates exceptional virus neutralization potency against all variants tested to date, it is also anticipated to maintain its activity against future variants because of the unique nature of the epitope. There is still a strong and urgent medical need for novel antibodies that work against both the newest as well as future SARS-CoV-2 variants, and these new data again demonstrate that XVR013m has the potential to become a durable therapeutic solution to protect the most vulnerable patients from this serious infectious disease.”

About ExeVir Bio

ExeVir Bio is a clinical stage biotechnology company developing heavy-chain only antibody therapies focusing on infectious diseases. The company is harnessing its llama-derived antibody (VHH) technology platform to generate multi-specific antibodies for prophylaxis and treatment of infectious diseases. ExeVir’s initial focus is on prevention of COVID-19 for the immunocompromised patient population, including active chemotherapy, immunosuppressive drugs, solid organ transplantation, hematological malignancies, AIDS patients, and for the elderly, where there remains a high unmet need due to the limitations of current vaccines and therapeutic approaches.

ExeVir has demonstrated it can progress its candidates from research to the clinic in under one year, execute on Phase 1a and Phase 1b studies, and conduct scale-up manufacturing. Leveraging this extensive experience, its XVR013m asset is being developed to start a First in Human clinical trial in 2025.

VHHs are smaller in size than whole antibodies, giving them access to hidden epitopes that traditional monoclonal antibodies are unable to reach with potential for deeper tissue penetration and simpler, more cost-effective manufacturing. VHHs can be linked together like building blocks into single multispecific molecules to tackle different epitopes or act through different mechanisms of actions at once, to address the “arms race” in more complex and co-evolving infectious diseases.

ExeVir is a spin out of VIB, the leading Belgium-based life sciences research institute. It is backed by strong investors including Fund+, which led the series A of EUR 42 million, together with an international consortium including UCB Ventures, SFPIM, V-Bio Ventures, VIB, Wallonie Entreprendre, Noshaq, Vives IUF and SambrInvest. ExeVir has received support from VLAIO, the SPW-Recherche and the European Union, leading to a total of EUR 18 million in non-dilutive funding. In 2023, ExeVir secured an option for EUR 25 million venture debt financing from the European Investment Bank.

Promising Anti-tumor Activity of Novel Costimulatory Bispecific Antibody REGN7075 (EGFRxCD28) in Combination with Libtayo® (cemiplimab) to be Reported at ASCO

Posted on by

Oral presentation to highlight activity of REGN7075 in combination with Libtayo from dose-escalation portion of trial in patients with microsatellite stable colorectal cancer, which has historically proven unresponsive to immunotherapy

Ongoing REGN7075 Phase 1/2 trial is investigating a potentially first-in-class combination across a range of advanced solid tumors

TARRYTOWN, N.Y., May 23, 2024 (GLOBE NEWSWIRE) — Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced positive new results from an ongoing Phase 1/2 trial evaluating its first-in-class costimulatory bispecific antibody, REGN7075 (EGFRxCD28), in combination with Libtayo® (cemiplimab) in patients with advanced solid tumors. Data from the dose-escalation portion of the trial showed the investigational combination led to anti-tumor responses in patients with microsatellite stable colorectal cancer (MSS CRC). REGN7075 is one of the first immunotherapies to demonstrate clinical activity in MSS CRC, including in a patient with liver metastases. The results will be shared during an oral session at the American Society of Clinical Oncology (ASCO) 2024 Annual Meeting in Chicago.

“Microsatellite stable colorectal cancer has historically been unresponsive to immunotherapy,” said Neil H. Segal, M.D., Ph.D., Medical Oncologist and Research Director in the Division of Gastrointestinal Oncology at Memorial Sloan Kettering Cancer Center, and a trial investigator. “The early results for this novel investigational EGFRxCD28 costimulatory bispecific in combination with Libtayo are encouraging, showing anti-tumor responses in a highly difficult-to-treat cancer. This combination is one of the first immunotherapy regimens to show clinical activity in microsatellite stable colorectal cancer, and we are excited to advance this trial in additional tumor types.”

In the dose-escalation portion of the trial, patients with metastatic and locally advanced solid tumors – who had exhausted standard treatment options, and most of whom also had liver metastases – received combination therapy with REGN7075 and Libtayo, following a REGN7075 monotherapy lead-in dose. Among 94 patients treated as of data cutoff, 65% (n=61) had MSS CRC, of which 51 MSS CRC patients were treated at an active dose level. Efficacy results among these 51 patients were as follows:

  • 6% (n=3) overall response rate (ORR) and 29% (n=15) disease control rate (DCR). This included one complete response (CR), two partial responses (PR), and 12 patients with stable disease. At data cutoff, all responders were without liver metastases.
  • Among the subset of 15 patients without liver metastases, there was a 20% ORR (n=3) and 80% DCR (n=12).
  • Among the subset of 36 patients with liver metastases, three patients had stable disease as of data cutoff, and one patient achieved a PR following data cutoff.

Safety was assessed in 84 patients across multiple solid tumor types at a variety of doses of REGN7075. REGN7075 and Libtayo showed an acceptable safety profile, and the maximum tolerated dose was not reached. Treatment-emergent adverse events (TEAEs) of any grade occurred in 98% of patients; Grade 3 and 4 TEAEs occurred in 35% of patients. Treatment-related adverse events (TRAEs) occurred in 90% of patients, with 7% of cases reported as grade 3 or 4. The majority of TRAEs were Grade 1 to 2 (83%), with the most common being infusion-related reactions (58%) that were manageable with premedication and dosing adjustments. TRAEs led to discontinuation in 5% of patients, and three patients discontinued treatment due to Grade 2 infusion-related reactions. As of data cutoff, there have been no dose-limiting toxicities, no reports of cytokine release syndrome, and no treatment-related deaths.

“Regeneron is focused on developing a unique investigational portfolio of oncology medicines including checkpoint inhibitors, CD3 bispecifics and CD28 costimulatory bispecifics. Over the past several years, we have made progress in our programs across checkpoint inhibitors and the CD3 class and are now showing promising activity with two costimulatory bispecific antibodies,” said Israel Lowy, M.D., Ph.D., Senior Vice President, Translational and Clinical Oncology at Regeneron. “Our costimulatory bispecifics were designed with the goal of turning cancer cells into antigen presenting cells, thereby converting historically immunotherapy unresponsive tumors from ‘cold’ to ‘hot’. These early data speak to the potential of REGN7075 in combination with Libtayo and add to a growing body of evidence supporting novel costimulatory bispecifics that are in clinical trials for a range of solid tumors and blood cancers.”

The combination of REGN7075 and Libtayo is currently under clinical development, and its safety and efficacy have not been fully evaluated by any regulatory authority. While the dose escalation portion of the trial across multiple solid tumor types including non-small cell lung cancer, colorectal cancer, head and neck cancer and other tumor types is ongoing, expansion cohorts in several tumor types have also been initiated.

About the Phase 1/2 Trial
The Phase 1/2, first-in-human, open-label trial investigating REGN7075 in combination with Libtayo is currently enrolling patients with metastatic and locally advanced solid tumors who have exhausted standard treatment options. The trial includes an ongoing Phase 1 dose-escalation portion and a Phase 2 dose-expansion period. In the Phase 1 dose-escalation portion, patients first receive a weekly lead-in dose of REGN7075 monotherapy for three weeks to assess its safety and efficacy alone. This is followed by treatment with combination therapy, with Libtayo dosed once every three weeks and REGN7075 dosed either every week or every three weeks. The primary endpoints are assessing safety and tolerability, while the secondary endpoints are assessing efficacy, pharmacokinetics and immunogenicity. Expansion cohorts in several tumor types have been initiated. For more information, visit the Regeneron clinical trials website, or contact via clinicaltrials@regeneron.com or 844-734-6643.

IMPORTANT SAFETY INFORMATION FOR U.S. PATIENTS

What is the most important information I should know about LIBTAYO?
LIBTAYO is a medicine that may treat certain cancers by working with your immune system. LIBTAYO can cause your immune system to attack normal organs and tissues in any area of your body and can affect the way they work. These problems can sometimes become severe or life-threatening and can lead to death. You can have more than one of these problems at the same time. These problems may happen anytime during treatment or even after your treatment has ended.

Call or see your healthcare provider right away if you develop any new or worsening signs or symptoms, including:

  • Lung problems: cough, shortness of breath, or chest pain
  • Intestinal problems: diarrhea (loose stools) or more frequent bowel movements than usual, stools that are black, tarry, sticky or have blood or mucus, or severe stomach-area (abdomen) pain or tenderness
  • Liver problems: yellowing of your skin or the whites of your eyes, severe nausea or vomiting, pain on the right side of your stomach-area (abdomen), dark urine (tea colored), or bleeding or bruising more easily than normal
  • Hormone gland problems: headache that will not go away or unusual headaches, eye sensitivity to light, eye problems, rapid heartbeat, increased sweating, extreme tiredness, weight gain or weight loss, feeling more hungry or thirsty than usual, urinating more often than usual, hair loss, feeling cold, constipation, your voice gets deeper, dizziness or fainting, or changes in mood or behavior, such as decreased sex drive, irritability, or forgetfulness
  • Kidney problems: decrease in your amount of urine, blood in your urine, swelling of your ankles, or loss of appetite
  • Skin problems: rash, itching, skin blistering or peeling, painful sores or ulcers in mouth or nose, throat, or genital area, fever or flu-like symptoms, or swollen lymph nodes
  • Problems can also happen in other organs and tissues. These are not all of the signs and symptoms of immune system problems that can happen with LIBTAYO. Call or see your healthcare provider right away for any new or worsening signs or symptoms, which may include: chest pain, irregular heartbeat, shortness of breath or swelling of ankles, confusion, sleepiness, memory problems, changes in mood or behavior, stiff neck, balance problems, tingling or numbness of the arms or legs, double vision, blurry vision, sensitivity to light, eye pain, changes in eyesight, persistent or severe muscle pain or weakness, muscle cramps, low red blood cells, or bruising
  • Infusion reactions that can sometimes be severe or life-threatening. Signs and symptoms of infusion reactions may include: nausea, vomiting, chills or shaking, itching or rash, flushing, shortness of breath or wheezing, dizziness, feel like passing out, fever, back or neck pain, or facial swelling
  • Rejection of a transplanted organ. Your healthcare provider should tell you what signs and symptoms you should report and monitor you, depending on the type of organ transplant that you have had
  • Complications, including graft-versus-host disease (GVHD), in people who have received a bone marrow (stem cell) transplant that uses donor stem cells (allogeneic). These complications can be serious and can lead to death. These complications may happen if you underwent transplantation either before or after being treated with LIBTAYO. Your healthcare provider will monitor you for these complications

Getting medical treatment right away may help keep these problems from becoming more serious. Your healthcare provider will check you for these problems during your treatment with LIBTAYO. Your healthcare provider may treat you with corticosteroid or hormone replacement medicines. Your healthcare provider may also need to delay or completely stop treatment with LIBTAYO if you have severe side effects.

Before you receive LIBTAYO, tell your healthcare provider about all your medical conditions, including if you:

  • have immune system problems such as Crohn’s disease, ulcerative colitis, or lupus
  • have received an organ transplant
  • have received or plan to receive a stem cell transplant that uses donor stem cells (allogeneic)
  • have received radiation treatment to your chest area
  • have a condition that affects your nervous system, such as myasthenia gravis or Guillain-Barré syndrome
  • are pregnant or plan to become pregnant. LIBTAYO can harm your unborn baby
  • are breastfeeding or plan to breastfeed. It is not known if LIBTAYO passes into your breast milk. Do not breastfeed during treatment and for at least 4 months after the last dose of LIBTAYO

Females who are able to become pregnant:

  • Your healthcare provider will give you a pregnancy test before you start treatment
  • You should use an effective method of birth control during your treatment and for at least 4 months after your last dose of LIBTAYO. Talk to your healthcare provider about birth control methods that you can use during this time
  • Tell your healthcare provider right away if you become pregnant or think you may be pregnant during treatment with LIBTAYO

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

The most common side effects of LIBTAYO when used alone include tiredness, muscle or bone pain, rash, diarrhea, and low levels of red blood cells (anemia). The most common side effects of LIBTAYO when used in combination with platinum-containing chemotherapy include hair loss, muscle or bone pain, nausea, tiredness, numbness, pain, tingling, or burning in your hands or feet, and decreased appetite. These are not all the possible side effects of LIBTAYO. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088. You may also report side effects to Regeneron Pharmaceuticals at 1-877-542-8296.

Cimeio Therapeutics : CD45 ADC and Shielded HSCs Represent a Potentially Universal Therapy for Blood Cancers

Posted on by

— Selective and complete eradication of leukemic cells with an ADC targeting the pan-blood marker CD45 —

— Engineered hematopoietic Stem Cells (HSCs) shielded from the CD45-targeting ADC maintain full functionality —

— Represents a novel, potentially universal approach to treating blood cancers —

BASEL, Switzerland & CAMBRIDGE, Mass.–(BUSINESS WIRE)–Cimeio Therapeutics today announced a publication in Nature showing that its CD45 antibody-drug conjugate (ADC) eradicated aggressive leukemic cells in vivo, while hematopoiesis was fully preserved and protected from the ADC via shielded hematopoietic stem cells (HSCs). The findings point to a novel and potentially universal approach to treating blood cancers.

CD45 is highly expressed on blood cancers but also on healthy blood cells. This profile until now has prevented effective targeting for therapeutic purposes. Now, a group led by Dr. Lukas Jeker, and researchers at Cimeio have shown that acute myeloid leukemia (AML) cells can be eliminated using Cimeio’s proprietary CD45-targeting ADC. By transplanting engineered HSCs that are shielded from the CD45-directed therapy, the CD45 ADC was safely and effectively administered against the blood cancers.

This work is foundational for the emerging field called epitope shielding, which enables the development of curative therapies for patients with hematologic diseases, severe autoimmune conditions and potentially infectious diseases such as HIV. The core patent for epitope shielding is exclusively licensed to Cimeio by University of Basel.

“All AML cells express CD45 but since all healthy blood cells also express it, killing cells that express CD45 results in severe toxicity,” said Dr. Jeker, who is the co-founder of Cimeio and Professor of Experimental Transplantation Immunology & Nephrology at the Basel University Hospital, Switzerland. “We solved the problem by providing epitope-shielded HSCs, which enable the ADC to selectively deplete cancer cells while sparing the healthy ones.”

“We believe that this therapy could change the treatment paradigm for patients with AML, which is a difficult-to-treat disease with a five-year survival rate of only 25%,” said Stefanie Urlinger, Ph.D., Chief Scientific Officer at Cimeio. “By protecting a patient’s heme system from toxicity, we are able to develop new targeted treatments previously not possible.”

Cimeio Therapeutics is developing epitope engineered cells and paired targeted therapies for CD45 and CD117, and epitope engineered cells for CD33, CD52, and several other heme targets.

About Cimeio Therapeutics

Cimeio is an immunotherapy company developing Shielded-Cell & Immunotherapy Pairs™ (SCIP), novel immunotherapies which have the potential to transform treatment of hematologic diseases. Cimeio develops immunotherapies, along with paired, modified variants of naturally occurring cell surface proteins in HSCs. These novel epitopes edited variants maintain their function but are resistant to depletion when targeted by a paired immunotherapy which has high affinity for the wild-type version of these proteins. These immunotherapies have significant therapeutic potential, which Cimeio is using to develop curative treatments for patients with hematologic malignancies, autoimmune disorders, and genetic diseases. Shielded Cell and Immunotherapy Pairs and SCIP are trademarks of Cimeio Therapeutics, Inc. For more information, please visit www.cimeio.com.

Alpha Cancer Technologies (ACT) Publishes Pre-Clinical Study Results in Cancer Cell International Demonstrating Excellent Safety and Significant Anti-Tumor Activity from the Company’s Next Generation ADC, ACT-903




Alpha Cancer Technologies (ACT) Publishes Pre-Clinical Study Results in Cancer Cell International Demonstrating Excellent Safety and Significant Anti-Tumor Activity from the Company’s Next Generation ADC, ACT-903

ACT-903 conjugate demonstrated significant anti-tumor activity, with tumors becoming undetectable in 9 of 10 mice, and all 10 mice surviving through Day 60 with no obvious signs of toxicity

ACT’s technology highlights the potential to use the natural function of AFP as a carrier protein to deliver a payload uniquely targeted to cancer cells, while reducing risk of immune reactions or anti-drug antibody accumulation

Alpha fetoprotein conjugates had a very low percentage of free toxin detectable in blood after administration, and did not show any bone marrow accumulation of cytotoxic payload, suggesting limited off-target toxicity

TORONTO–(BUSINESS WIRE)–#ACT903–Alpha Cancer Technologies Inc. (ACT), a biopharmaceutical company focused on developing and commercializing targeted immuno-oncology and immunomodulation therapies based on its proprietary recombinant human Alpha Fetoprotein (AFP) platform, today announced the publication of pre-clinical study results in Cancer Cell International highlighting the company’s recombinant human AFP (ACT-101) conjugate with maytansine in mouse xenograft models of colorectal cancer. Results from the study demonstrate the exceptional safety profile and potent anti-tumor activity of multiple ACT-101 conjugates through the successful targeting of the alpha fetoprotein receptor uniquely located on cancerous cells and myeloid-derived suppressor cells (MDSCs).

The AFP receptor has been found on the surface of cancer cells and MDSCs exclusively, making it an attractive target for the delivery of toxins selectively to tumor cells and MDSCs. Human AFP acts as a shuttle protein, transporting a variety of molecules including targeted anti-cancer agents inside the cell via the AFP receptor. ACT-101 is a recombinantly produced non-glycosylated form of human AFP, which will carry and deliver maytansine and other chemotherapy payloads to tumor cells via the AFP receptor. The selection of maytansine was based on its prior efficacy in clinical studies when incorporated into ADCs.

The AFP receptor has emerged as a novel target for cancer therapeutics given the expression of AFP on most cancers and MDSCs, and lack of presence on normal tissues. Studies were performed to investigate the use of ACT-101 conjugated with maytansine for targeted toxin delivery to cancer. Four structurally different ACT-101-maytansinoid conjugates containing cleavable glutathione sensitive linkers were initially investigated in a mouse xenograft model of colorectal cancer (COLO-205). Reduction in tumor volume was seen for all four conjugates compared to control (p < 0.05). The anti-tumor effects of the conjugate selected for further development, ACT-903, persisted after treatment discontinuation, with tumors becoming undetectable in 9 of 10 mice, and all 10 mice surviving through Day 60 with no obvious signs of toxicity. A follow-up study performed in the same model compared the effects of single intravenous doses of ACT-903 (10–50 mg/kg) to control groups receiving vehicle or ACT-101. A significant reduction of tumor burden compared to control was achieved in the 40 and 50 mg/kg dose groups. Survival was also significantly prolonged in the 40 mg/kg and 50 mg/kg cohorts. Free maytansine blood levels at 4 hours were 0.008% of the dose, indicating stability in circulation as was expected based on in vitro plasma stability studies. No obvious signs of toxicity were seen in any of the treated groups. The observed efficacy and excellent tolerability of ACT-903 in these xenograft models support advancing the development of ACT-903 into clinical studies.

“Based on the evidence we continue to observe in our pre-clinical studies, we believe ACT-903 has the potential to address the limitations of current-generation antibody drug conjugates through a targeted delivery exclusively to cancer and immune suppressor cells, allowing for greater efficacy with minimal toxicity,” said Dr. Igor Sherman, CEO of ACT. “Given the broad range of cancer cells expressing the AFP receptor, we believe our technology offers a potential pan-cancer opportunity and we look forward to continuing the development of this program to bring it to cancer patients in the shortest possible time.”

The manuscript, titled “High anti-tumor activity of a novel alpha-fetoprotein-maytansinoid conjugate targeting alpha-fetoprotein receptors in colorectal cancer xenograft model,” was published in Cancer Cell International on April 5, 2023 and the full manuscript can be accessed here.
