CAMBRIDGE, Mass.–(BUSINESS WIRE)–Scholar Rock (NASDAQ: SRRK), a late-stage biopharmaceutical company focused on advancing innovative treatments for spinal muscular atrophy (SMA), cardiometabolic disorders, and other serious diseases where protein growth factors play a fundamental role, today reported financial results and corporate updates for the first quarter ended March 31, 2024.


Scholar Rock is now only two quarters away from reporting topline data for our pivotal Phase 3 SAPPHIRE trial, which has the potential to build upon the promising data generated from our prior Phase 2 trial,” said Jay Backstrom, M.D., MPH, President & Chief Executive Officer of Scholar Rock. “As we look towards a potential commercial launch of apitegromab in SMA in 2025, we’re thrilled to be on the precipice of delivering a new class of treatment with potential to meaningfully impact people living with SMA.”

Dr. Backstrom continued, “In parallel, we continue to make important progress with our cardiometabolic program. As we advance SRK-439 towards IND, we plan to present new preclinical data at upcoming conferences that further support SRK-439’s differentiated product profile. Additionally, we remain on track to open enrollment in June for our Phase 2 proof-of-concept trial evaluating apitegromab in combination with GLP-1 agonist treatment in obesity, which is designed to assess the effect of our selective approach to blocking myostatin to preserve lean muscle mass as part of healthy weight management. As a leader in selective myostatin inhibition, it is a priority for us to apply our expertise in the cardiometabolic arena, where safe preservation of lean muscle mass is important.”

Company Highlights and Upcoming Milestones

SMA Program

Apitegromab is an investigational, fully human monoclonal antibody that inhibits myostatin activation by selectively binding the pro- and latent forms of myostatin in skeletal muscle and is being developed as a potential first muscle-targeted therapy for the treatment of SMA. Apitegromab is the only muscle-targeted therapy to show clinical proof-of-concept in SMA.

  • On track to report topline data from Phase 3 SAPPHIRE clinical trial in 4Q 2024. If the trial is successful and apitegromab is approved, the Company expects to initiate a commercial product launch in 2025.
  • ONYX long-term extension study ongoing for patients from both the TOPAZ and SAPPHIRE studies. More than 90% of patients on combination therapy have completed 4 years of apitegromab treatment and enrolled into ONYX.

Cardiometabolic Program

SRK-439 is a novel, preclinical, investigational myostatin inhibitor that has high in vitro affinity for pro- and latent myostatin and maintains myostatin specificity (i.e., no GDF11 or Activin A binding), and is initially being developed for the treatment of obesity.

  • Initiating a Phase 2 proof-of-concept trial with apitegromab in combination with a GLP-1 receptor agonist (GLP-1 RA) in obesity in June. The Phase 2 trial is a randomized, double-blind, placebo-controlled, multi-center study to evaluate the effect of apitegromab, a highly selective myostatin inhibitor, to preserve lean muscle mass as an adjunctive therapy in overweight and obese adults who are taking a GLP-1 RA. Data is expected in mid-2025 and will be used to guide clinical development of SRK-439. The Company plans to file an IND for SRK-439 for the treatment of obesity in 2025.
  • Preclinical data from the SRK-439 program selected for an oral presentation during the American Diabetes Association 84th Scientific Sessions being held June 21-24, 2024 in Orlando, Florida. The presentation will include updates on SRK-439 and will be held on June 23 at 2:45 p.m. ET.

Immuno-Oncology Program

SRK-181 is an investigational selective inhibitor of latent TGFβ1 activation and developed with the aim of overcoming resistance to checkpoint therapy in patients with advanced cancer.

  • New SRK-181 data from the Phase 1 DRAGON proof-of-concept trial selected for an oral presentation at the ASCO Annual Meeting being held May 31- June 4, 2024 in Chicago. Enrollment of the DRAGON trial was completed in December 2023, and patients who remain on the study continue to be treated. The presentation, “Phase 1 study (DRAGON) of SRK-181 (linavonkibart), a latent TGFβ1 inhibitor, combined with pembrolizumab in anti-PD1 resistant patients with advanced solid tumors: updated results of expansion part,” will be presented on June 3 at 1:50 p.m. CT/2:50 p.m. ET. The Company will hold a webcast to discuss the data from the ASCO presentation on June 4 at 8:00 a.m. ET.

Corporate

  • Company hosting Investor & Analyst Day on May 22, 2024 in New York City. Event to highlight the Company’s myostatin inhibition programs in SMA and obesity.

First Quarter 2024 Financial Results

For the quarter ended March 31, 2024, net loss was $56.9 million or $0.59 per share compared to a net loss of $39.4 million or $0.49 per share for the quarter ended March 31, 2023.

  • The Company did not record any revenue for the quarter ended March 31, 2024 or for the quarter ended March 31, 2023.
  • Research and development expense was $43.1 million for the quarter ended March 31, 2024, compared to $29.7 million for the quarter ended March 31, 2023. The increase was primarily attributable to clinical trial and research study costs.
  • General and administrative expense was $15.3 million for the quarter ended March 31, 2024, compared to $10.8 million for the quarter ended March 31, 2023. The increase was due to employee-related costs.
  • As of March 31, 2024, Scholar Rock had cash, cash equivalents, and marketable securities of approximately $238 million, which is expected to fund the Company’s anticipated operating and capital expenditure requirements into the second half of 2025.

We are acutely focused on execution in 2024 as we prepare for the pivotal Phase 3 readout of apitegromab in SMA and continue to progress our cardiometabolic program through clinical development. Our cash position enables us to reach multiple upcoming key milestones as we prepare for our next phase of growth,” said Ted Myles, Chief Operating Officer and Chief Financial Officer of Scholar Rock.

About the Phase 3 SAPPHIRE Trial

SAPPHIRE is an ongoing randomized, double-blind, placebo-controlled, Phase 3 clinical trial evaluating the safety and efficacy of apitegromab in nonambulatory patients with Types 2 and 3 SMA who are receiving SMN-targeted therapy (either nusinersen or risdiplam). SAPPHIRE targeted enrolling approximately 156 patients aged 2-12 years old in the main efficacy population. These patients were randomized 1:1:1 to receive for 12 months either apitegromab 10 mg/kg, apitegromab 20 mg/kg, or placebo by intravenous (IV) infusion every 4 weeks. An exploratory population that targeted enrolling up to 48 patients aged 13-21 years old will also separately be evaluated. These patients were randomized 2:1 to receive either apitegromab 20 mg/kg or placebo. For more information about SAPPHIRE, visit www.clinicaltrials.gov. Apitegromab has not been approved for any use by the US FDA or any other health authority, and its safety and efficacy have not been established.

About SRK-439

SRK-439 is a novel, preclinical, investigational myostatin inhibitor that has high in vitro affinity for pro- and latent myostatin and maintains myostatin specificity (i.e., no GDF11 or Activin-A binding), and is initially being developed for the treatment of obesity. Based on preclinical data, SRK-439 has the potential to support healthier weight management by preserving lean mass. The efficacy and safety of SRK-439 have not been established and SRK-439 has not been approved for any use by the FDA or any other regulatory agency.
