FDA Approves Genentech’s Tecentriq in Combination With Avastin and Chemotherapy for the Initial Treatment of People With a Specific Type of Metastatic Lung Cancer

– Approval based on survival benefit of Tecentriq, in combination
with Avastin, paclitaxel and carboplatin (chemotherapy), in people with
metastatic non-squamous non-small cell lung cancer (NSCLC) with no EGFR
or ALK genomic tumor aberrations compared to Avastin plus chemotherapy –

SOUTH SAN FRANCISCO, Calif.–(BUSINESS WIRE)–Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY),
today announced that the U.S. Food and Drug Administration (FDA)
approved Tecentriq® (atezolizumab), in combination
with Avastin® (bevacizumab), paclitaxel and carboplatin
(chemotherapy), for the initial (first-line) treatment of people with
metastatic non-squamous non-small cell lung cancer (NSCLC) with no EGFR
or ALK genomic tumor aberrations.

“This Tecentriq regimen has demonstrated a significant survival benefit
in the initial treatment of metastatic non-squamous non-small cell lung
cancer,” said Sandra Horning, M.D., chief medical officer and head of
Global Product Development. “Today’s approval supports our combination
approach for Tecentriq in lung cancer and our vision to develop
medicines that improve outcomes for patients with this complex disease.”

This approval is based on results from the Phase III IMpower150 study,
which showed that Tecentriq in combination with Avastin and chemotherapy
helped people live significantly longer compared to Avastin and
chemotherapy (median overall survival [OS] = 19.2 versus 14.7 months;
hazard ratio [HR] = 0.78; 95 percent CI: 0.64-0.96; p=0.016) in the
intention-to-treat wild-type (ITT-WT) population. The safety profile of
the Tecentriq combination was consistent with that observed in previous
studies.

Genentech is working with the FDA on postmarketing commitments (PMCs) to
better understand and characterize the potential effects of
Tecentriq-related anti-drug antibodies (ADAs) and neutralizing
antibodies (NAbs) across all of our studies. An analysis of ADAs in the
IMpower150 study showed no impact on the efficacy of Tecentriq.

Tecentriq is also approved by the FDA to treat people with metastatic
NSCLC who have disease progression during or following
platinum-containing chemotherapy, and have progressed on an appropriate
FDA-approved targeted therapy if their tumor has EGFR or ALK genetic
alterations.

For those who qualify, Genentech offers patient assistance programs for
people taking Tecentriq through Genentech Access Solutions. Doctors can

About the IMpower150 study

IMpower150 is a multicenter, open-label, randomized, controlled Phase
III study evaluating the efficacy and safety of Tecentriq in combination
with chemotherapy (carboplatin and paclitaxel) with or without Avastin
in people with Stage IV or recurrent metastatic non-squamous NSCLC who
had not been treated with chemotherapy for their advanced disease. It
enrolled 1,202 people, of whom 1,045 were in the ITT-WT subpopulation,
which excluded those people with EGFR and ALK mutations.

People were randomized (1:1:1) to receive:

  • Tecentriq plus carboplatin and paclitaxel (Arm A), or
  • Tecentriq and Avastin plus carboplatin and paclitaxel (Arm B), or
  • Avastin plus carboplatin and paclitaxel (Arm C, control arm).

The co-primary endpoints comparing Arms B and C were progression-free
survival (PFS) as determined by the independent review facility (IRF)
using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST
v1.1) and OS and assessed in the ITT-WT subpopulation. Key secondary
endpoints included IRF-assessed PFS, OS and safety in the ITT population.

A summary of the ITT-WT data from the IMpower150 study that support this
approval is included below.

  • Tecentriq in combination with Avastin and chemotherapy helped people
    live significantly longer compared to Avastin and chemotherapy (median
    OS=19.2 versus 14.7 months; HR=0.78, 95 percent CI: 0.64-0.96;
    p=0.016).
  • In addition, Tecentriq in combination with Avastin and chemotherapy
    reduced risk of disease worsening or death (PFS) by 29 percent
    compared to Avastin and chemotherapy (HR=0.71, 95 percent CI:
    0.59-0.85, p=0.0002).
  • Tecentriq in combination with Avastin and chemotherapy shrank tumors
    (overall response rate; ORR) in 55 percent of people (95 percent CI:
    49-60) compared to 42 percent of people (95 percent CI: 37-48) on
    Avastin and chemotherapy

    • 4 percent of people receiving Tecentriq in combination with
      Avastin and chemotherapy experienced a complete response (CR), and
      51 percent of people experienced a partial response (PR).
  • The median duration of response (DoR) for people receiving Tecentriq
    in combination with Avastin and chemotherapy was 10.8 months (95
    percent CI: 8.4-13.9) compared to 6.5 months (95 percent CI: 5.6-7.6)
    for people on Avastin and chemotherapy.
  • The most common adverse reactions (≥20 percent) in people receiving
    Tecentriq in combination with Avastin and chemotherapy were fatigue
    and lack of energy (asthenia; 50 percent), hair loss (alopecia; 48
    percent), nausea (39 percent), diarrhea (32 percent), constipation (30
    percent), decreased appetite (29 percent), joint pain (arthralgia; 26
    percent), hypertension (25 percent) and pain from nerve damage
    (peripheral neuropathy; 24 percent).

About lung cancer

According to the American Cancer Society, it is estimated that more than
234,000 Americans will be diagnosed with lung cancer in 2018, and NSCLC
accounts for 85 percent of all lung cancers. It is estimated that
approximately 60 percent of lung cancer diagnoses in the United States
are made when the disease is in the advanced stages.

About Tecentriq® (atezolizumab)

Tecentriq is a monoclonal antibody designed to bind with a protein
called PD-L1. Tecentriq is designed to bind to PD-L1 expressed on tumor
cells and tumor-infiltrating immune cells, blocking its interactions
with both PD-1 and B7.1 receptors. By inhibiting PD-L1, Tecentriq may
enable the re-activation of T cells. Tecentriq may also affect normal
cells.

About Avastin® (bevacizumab)

Avastin is a prescription-only medicine that is a solution for
intravenous infusion. It is a biologic antibody designed to specifically
bind to a protein called vascular endothelial growth factor (VEGF) that
plays an important role throughout the lifecycle of the tumor to develop
and maintain blood vessels, a process known as angiogenesis. Avastin is
designed to interfere with the tumor blood supply by directly binding to
the VEGF protein to prevent interactions with receptors on blood vessel
cells. The tumor blood supply is thought to be critical to a tumor’s
ability to grow and spread in the body (metastasize).

Tecentriq U.S. Indication (pronounced ‘tē-SEN-trik’)

Tecentriq is a prescription medicine used to treat:

A type of bladder and urinary tract cancer called urothelial
carcinoma.
Tecentriq may be used when your bladder cancer:

  • has spread or cannot be removed by surgery, and if you have any one
    of the following conditions
    :

    • you are not able to take chemotherapy that contains a medicine
      called cisplatin, and your doctor has tested your cancer and found
      high levels of a specific protein on your cancer called programmed
      death-ligand 1 (PD-L1), or
    • you are not able to take chemotherapy that contains any platinum
      regardless of the levels of PD-L1 on your cancer, or
    • you have tried chemotherapy that contains platinum, and it did not
      work or is no longer working

The approval of Tecentriq in these patients is based on a study that
measured response rate and duration of response. There is an ongoing
study to confirm clinical benefit.

A type of lung cancer called non-small cell lung cancer (NSCLC).

  • Tecentriq may be used with bevacizumab and the chemotherapy
    medicines carboplatin and paclitaxel as your first treatment when your
    lung cancer:

    • has spread or grown, and
    • is a type of lung cancer called non-squamous NSCLC
    • your tumor does not have an abnormal “EGFR” or “ALK” gene
  • Tecentriq may be used when your lung cancer:

    • has spread or grown, and
    • you have tried chemotherapy that contains platinum, and it did not
      work or is no longer working
    • If your tumor has an abnormal EGFR or ALK gene, you should have
      also tried an FDA-approved therapy for tumors with these abnormal
      genes, and it did not work or is no longer working.

It is not known if Tecentriq is safe and effective in children.

Patients should call or see their healthcare provider right away if
they get any symptoms of the following problems or these symptoms get
worse.

Getting medical treatment right away may help keep these problems
from becoming more serious.
A healthcare provider may treat patients
with corticosteroid or hormone replacement medicines. A healthcare
provider may delay or completely stop treatment with Tecentriq if
patients have severe side effects.

Before receiving Tecentriq, patients should tell their healthcare
provider about all of their medical conditions, including if they:

  • have immune system problems (such as Crohn’s disease, ulcerative
    colitis, or lupus); have had an organ transplant; have lung or
    breathing problems; have liver problems; have a condition that affects
    the nervous system (such as myasthenia gravis or Guillain-Barre
    syndrome); or are being treated for an infection
  • are pregnant or plan to become pregnant. Tecentriq can harm an unborn
    baby. Patients should tell their healthcare provider right away if
    they become pregnant or think they may be pregnant during treatment
    with Tecentriq. Females who are able to become pregnant:

    • A healthcare provider should do a pregnancy test before they start
      treatment with Tecentriq
    • They should use an effective method of birth control during their
      treatment and for at least 5 months after the last dose of
      Tecentriq

Avastin Indications:

  • Metastatic colorectal cancer (mCRC) for first- or second-line
    treatment in combination with intravenous 5-fluorouracil–based
    chemotherapy. It is also approved to treat mCRC for second-line
    treatment, when used with fluoropyrimidine-based (combined with
    irinotecan or oxaliplatin) chemotherapy, after cancer progresses
    following a first-line treatment that includes Avastin.

    • Avastin is not approved for use after the primary treatment of
      colon cancer that has not spread to other parts of the body
  • Advanced nonsquamous non–small cell lung cancer (NSCLC) in
    combination with carboplatin and paclitaxel, in people who have not
    received chemotherapy for their advanced disease
  • Metastatic kidney cancer (mRCC) when used with interferon alfa
  • Glioblastoma (GBM) in adult patients whose cancer has
    progressed after prior treatment (recurrent or rGBM)
  • Advanced cervical cancer (CC) in combination with paclitaxel
    and cisplatin or paclitaxel and topotecan, is approved to treat
    persistent, recurrent, or metastatic cancer of the cervix
  • Ovarian cancer (OC). Avastin, in combination with carboplatin
    and paclitaxel, followed by Avastin alone, is used for the treatment
    of patients with advanced (Stage III or IV) epithelial ovarian,
    fallopian tube, or primary peritoneal cancer following initial surgery.

    Avastin
    in combination with paclitaxel, pegylated liposomal doxorubicin or
    topotecan, is approved to treat platinum-resistant recurrent
    epithelial ovarian, fallopian tube or primary peritoneal cancer (prOC)
    in women who received no more than two prior chemotherapy treatments.

    Avastin,
    either in combination with carboplatin and paclitaxel or with
    carboplatin and gemcitabine, followed by Avastin alone, is approved
    for the treatment of patients with platinum-sensitive recurrent
    epithelial ovarian, fallopian tube, or primary peritoneal cancer (psOC)

Possible serious side effects

Everyone reacts differently to Avastin therapy. So, it’s important to
know what the side effects are. Although some people may have a
life-threatening side effect, most do not
. Their doctor will stop
treatment if any serious side effects occur. Patients should contact
their health care team if there are any signs of these side effects.

Most serious side effects (not common, but sometimes fatal):

  • GI perforation. A hole that
    develops in the stomach or intestine. Symptoms include pain in the
    abdomen, nausea, vomiting, constipation, or fever
  • Wounds that don’t heal. A cut made
    during surgery can be slow to heal or may not fully heal. Avastin
    should not be used for at least 28 days before or after surgery and
    until surgical wounds are fully healed
  • Serious bleeding. This includes
    vomiting or coughing up blood; bleeding in the stomach, brain, or
    spinal cord; nosebleeds; and vaginal bleeding. If a patient has
    recently coughed up blood or had serious bleeding, they should be sure
    to tell their doctor

Other possible serious side effects

  • Abnormal passage in the body. This type of passage—known as a
    fistula—is an irregular connection from one part of the body to
    another and can sometimes be fatal
  • Severe high blood pressure. Blood pressure that severely spikes
    or shows signs of affecting the brain. Blood pressure should be
    monitored every 2 to 3 weeks while on Avastin and after stopping
    treatment
  • Kidney problems. These may be caused by too much protein in the
    urine and can sometimes be fatal
  • Infusion reactions. These were uncommon with the first dose
    (less than 3% of patients). 0.2% of patients had severe reactions.
    Infusion reactions include high blood pressure or severe high blood
    pressure that may lead to stroke, trouble breathing, decreased oxygen
    in red blood cells, a serious allergic reaction, chest pain, headache,
    tremors, and excessive sweating. The patient’s doctor or nurse will
    monitor for signs of infusion reactions
  • Severe stroke or heart problems. These may include blood clots,
    mini-stroke, heart attack, chest pain, and the heart may become too
    weak to pump blood to other parts of the body (congestive heart
    failure). These can sometimes be fatal
  • Nervous system and vision problems. Signs include headache,
    seizure, high blood pressure, sluggishness, confusion, and blindness

Side effects seen most often

In clinical studies across different types of cancer, some patients
experienced the following side effects:

  • High blood pressure
  • Too much protein in the urine
  • Nosebleeds
  • Rectal bleeding
  • Back pain
  • Headache
  • Taste change
  • Dry skin
  • Inflammation of the skin
  • Inflammation of the nose
  • Watery eyes

Avastin is not for everyone

Patients should talk to their doctor if they are:

  • Undergoing surgery. Avastin should not be used for 28 days
    before or after surgery and until surgical wounds are fully healed
  • Pregnant or think they are pregnant. Data have shown that
    Avastin may harm a woman’s unborn baby. Birth control should be used
    while patients are on Avastin. If Avastin is stopped, patients should
    keep using birth control for 6 months before trying to become pregnant
  • Planning to become pregnant. Taking Avastin could cause a
    woman’s ovaries to stop working and may impair her ability to have
    children
  • Breastfeeding. Breastfeeding while on Avastin may harm the baby
    and is therefore not recommended during and for 6 months after taking
    Avastin

Patients should talk with their doctor if they have any questions about
their condition or treatment.
