Phase III IMmotion151 Study Showed Genentech's TECENTRIQ (Atezolizumab) and Avastin (Bevacizumab) Reduced the Risk of Disease Worsening or Death for the Initial Treatment of Certain People with Advanced Kidney Cancer

Share:

– TECENTRIQ and Avastin showed improvement in investigator-assessed
progression-free survival (PFS) compared with sunitinib for people whose
disease expressed PD-L1 –

– Data will be discussed with health authorities globally, including
the U.S. Food and Drug Administration (FDA) and European Medicines
Agency (EMA) –

Genentech, a member of the Roche Group ((SIX: RO, ROG, OTCQX:RHHBY),
today announced that the Phase III IMmotion151 study met its co-primary
endpoint of investigator-assessed progression-free survival (PFS) and
demonstrated that the combination of TECENTRIQ®
(atezolizumab) and Avastin® (bevacizumab) provided a
statistically significant and clinically meaningful reduction in the
risk of disease worsening or death (PFS) in people whose disease
expressed the PD-L1 (programmed death-ligand 1; PD-L1 expression ≥1
percent) protein compared with sunitinib for the first-line treatment of
people who have advanced or metastatic renal cell carcinoma (mRCC).

Observations of a pre-specified subgroup analysis of the TECENTRIQ and
Avastin combination indicated that, in people whose disease expressed
PD-L1, a numerical difference favoring TECENTRIQ was seen across all
patient risk factor groups (favorable, intermediate and poor) compared
to sunitinib; however, due to the study design these data could not be
assessed for statistical significance and are descriptive only.
Assessment of secondary endpoints is ongoing. Safety for the TECENTRIQ
and Avastin combination appeared consistent with the known safety
profile of the individual medicines and what was previously reported in
the Phase II IMmotion150 study. No new safety signals were identified
with the combination.

Results will be presented at an upcoming oncology conference in 2018.
Top-line results from the co-primary endpoint of overall survival (OS)
are not mature.

"We are encouraged by these results as they add to the emerging body of
evidence that supports our rationale for this combination. We believe
that the regimen of TECENTRIQ and Avastin may enhance the potential of
the immune system in the initial treatment of advanced kidney cancer,"
said Sandra Horning, M.D., chief medical officer and head of Global
Product Development. "We will discuss these data with health authorities
globally and hope to bring this combination forward as a potential new
treatment option as soon as possible.''

IMmotion151 is the second successive positive Phase III study of
TECENTRIQ that includes an Avastin combination component as an initial
treatment. This follows the positive Phase III non-squamous non-small
cell lung cancer (NSCLC) IMpower150 study that showed TECENTRIQ and
Avastin plus chemotherapy demonstrated a PFS advantage over Avastin plus
chemotherapy.

About the IMmotion151 study

IMmotion151 is a Phase III multicenter, randomized, open-label study to
evaluate the efficacy and safety of TECENTRIQ and Avastin versus
sunitinib in people with inoperable, locally advanced or metastatic
renal cell carcinoma (RCC) who have not received prior systemic active
or experimental therapy. It enrolled 915 people globally who were
randomized 1:1 to receive TECENTRIQ and Avastin, or sunitinib alone.

People in the TECENTRIQ and Avastin arm received TECENTRIQ at a fixed
dose of 1200 milligrams (mg) and Avastin at a dose of 15 milligrams per
kilogram (mg/kg) via intravenous (IV) infusion every 3 weeks until loss
of clinical benefit or unacceptable toxicity. People in the sunitinib
arm received sunitinib 50 mg orally, once daily for 4 weeks followed by
2 weeks rest until loss of clinical benefit or unacceptable toxicity.

The co-primary endpoints were PFS, as determined by the investigator
using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST
v1.1) in people whose tumors expressed PD-L1 [PD-L1 expression ≥1
percent on immune cells (IC)], and OS in the overall study population
(intention-to-treat, ITT). PD-L1 expression was prospectively assessed
using an immunohistochemistry (IHC) test (SP142) developed by Roche
Tissue Diagnostics.

Stratification factors included the presence or absence of liver
metastases; level of IC staining for PD-L1 (≥1 percent vs. <1 percent)
and Memorial Sloan-Kettering Cancer Center (Motzer) risk score. The
Motzer prognostic scoring system predicts for OS based upon an
individual's baseline clinical and laboratory characteristics. Depending
on the presence of one or several of five variables (risk factors),
people are classified in one of the three risk groups: "Favorable" with
0 risk factors, "Intermediate" with 1-2 risk factors and "Poor" with ≥ 3
risk factors.

About renal cell carcinoma

According to the American Cancer Society, more than 63,000 people will
be diagnosed with kidney cancer in 2017. Renal cell carcinoma (RCC)
accounts for approximately 90 percent of all cases. RCC occurs when
abnormal cells develop in the tissue of the kidneys, specifically in the
small tubes (also known as tubules) where the blood is filtered.
Typically, RCC is a single tumor in one kidney but, in rare cases, there
can be multiple tumors, which can occur in one or both kidneys. Despite
recent progress in the field of kidney cancer, treatment options for
people with the disease remains limited.

About the TECENTRIQ (atezolizumab) and Avastin (bevacizumab)
combination

There is a strong scientific rationale to support further investigation
of TECENTRIQ plus Avastin in combination. We are investigating this
combination in a broad range of cancers, including advanced RCC.
Avastin, in addition to its anti-angiogenic effects, may further enhance
TECENTRIQ's ability to restore anti-cancer immunity, by inhibiting
VEGF-related immunosuppression, promoting T-cell tumor infiltration and
enabling priming and activation of T-cell responses against tumor
antigens.

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). Avastin is the
only currently available treatment for people with mRCC that directly
inhibits VEGF.

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 (advanced urothelial
      carcinoma), and
    • you are not able to take chemotherapy that contains a medicine
      called cisplatin, 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 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.

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.

Recurrent ovarian cancer (rOC). 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 talk to
their doctor 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

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