Genentech Presents Pivotal Data Demonstrating Tecentriq in Combination With Avastin Improves Overall Survival in People With the Most Common Form of Liver Cancer

– First Phase III cancer immunotherapy study to show an improvement in overall survival and progression-free survival in people with unresectable hepatocellular carcinoma compared with sorafenib –

– Results will be presented in the Presidential session at the European Society for Medical Oncology (ESMO) Asia Congress 2019 –

SOUTH SAN FRANCISCO, Calif.–(BUSINESS WIRE)–Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), will today present positive results from the Phase III IMbrave150 study evaluating Tecentriq^® (atezolizumab) in combination with Avastin^® (bevacizumab). The data show statistically significant and clinically meaningful improvements in overall survival (OS) and progression-free survival (PFS), compared with sorafenib, in people with unresectable hepatocellular carcinoma (HCC) who have not received prior systemic therapy.

Tecentriq in combination with Avastin reduced the risk of death (OS) by 42% (hazard ratio [HR]=0.58; 95% CI: 0.42-0.79; p=0.0006) and reduced the risk of disease worsening or death (PFS) by 41% (HR=0.59; 95% CI: 0.47-0.76; p<0.0001), compared with sorafenib. Safety for Tecentriq and Avastin was consistent with the known safety profiles of the individual medicines.

“For the first time in a decade, we are seeing a treatment that has improved overall survival for people with unresectable hepatocellular carcinoma compared with the current standard of care,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “Tecentriq in combination with Avastin could transform the treatment of this aggressive disease, and we are working closely with global health authorities in the hope of bringing this treatment option to patients as soon as possible.”

It is estimated that more than 42,000 people will be diagnosed with liver cancer in the U.S. this year, and approximately 75% will have HCC. Liver cancer is the most rapidly increasing cancer diagnosis in both men and women, with incidence rates more than tripling since 1980.

These data will be presented in the Presidential session at the European Society for Medical Oncology (ESMO) Asia Congress 2019 on November 23 at 11:00 a.m. (Singapore Standard time) (Abstract LBA3).

Genentech has an extensive development program for Tecentriq, including multiple ongoing and planned Phase III studies, across several types of lung, genitourinary, skin, breast, gastrointestinal, gynecological and head and neck cancers. This includes studies evaluating Tecentriq both alone and in combination with other medicines.

About the IMbrave150 study

IMbrave150 is a global Phase III, multicenter, open-label study of 501 people with unresectable HCC who have not received prior systemic therapy. People were randomized 2:1 to receive the combination of Tecentriq and Avastin or sorafenib. Tecentriq was administered intravenously (IV), 1200 mg on day 1 of each 21-day cycle, and Avastin was administered IV, 15 mg/kg on day 1 of each 21-day cycle. Sorafenib was administered by mouth, 400 mg twice per day, on days 1-21 of each 21-day cycle. People received the combination or the control arm treatment until unacceptable toxicity or loss of clinical benefit as determined by the investigator. Co-primary endpoints were OS and PFS by independent review facility (IRF) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1). Additional study endpoints included overall response rate (ORR), time to progression (TTP) and duration of response (DoR), as measured by RECIST v1.1 (investigator-assessed [INV] and IRF) and HCC mRECIST (IRF), as well as patient-reported outcomes (including time to deterioration of patient-reported quality of life), safety and pharmacokinetics.

Key efficacy endpoint results for OS and PFS (co-primary endpoints) are below:

	Tecentriq + Avastin (n=336)	Sorafenib (n=165)
Median OS (months) (95% CI)	NE	13.2 (10.4, NE)
OS, HR (95% CI)	0.58 (0.42, 0.79)
Log rank p-value	0.0006
Median PFS (months) (95% CI) IRF RECIST v1.1	6.8 (5.7, 8.3)	4.3 (4.0, 5.6)
PFS, HR (95% CI)	0.59 (0.47, 0.76)
Log rank p-value	<0.0001

NE, not estimable (Median OS for Tecentriq + Avastin not yet reached. For the control arm, the upper CI limit was not estimable); median follow-up 8.6 months; PFS measured as per IRF RECIST v1.1.

Grade 3-4 adverse events (AEs) occurred in 57% of people receiving Tecentriq and Avastin and 55% of people receiving sorafenib. Grade 5 AEs occurred in 5% and 6% of people, respectively.

About hepatocellular carcinoma

According to the American Cancer Society, it is estimated that more than 42,000 Americans will be diagnosed with liver cancer in 2019. HCC accounts for approximately 75% of all liver cancer cases in the United States. HCC develops predominantly in people with cirrhosis due to chronic hepatitis (B and C), and alcohol consumption, and typically presents at an advanced stage where there are limited treatment options.

About the Tecentriq and Avastin combination

There is a strong scientific rationale to support further investigation of Tecentriq plus Avastin in combination. Avastin, in addition to its anti-angiogenic effects, may further enhance Tecentriq’s ability to restore anti-cancer immunity by inhibiting vascular endothelial growth factor (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 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. Indications

Tecentriq is a prescription medicine used to treat adults with:

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 cancer tests positive for “PD-L1”, or
  • you are not able to take chemotherapy that contains any platinum regardless of “PD-L1” status, 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. Continued approval for this use may depend on the results of an ongoing study to confirm 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”, and
  • your tumor does not have an abnormal “EGFR” or “ALK” gene

• Tecentriq may be used alone 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, and
  • 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.

A type of breast cancer called triple-negative breast cancer (TNBC).

Tecentriq may be used with the medicine paclitaxel protein-bound when your breast cancer:

• has spread or cannot be removed by surgery, and
• your cancer tests positive for “PD-L1”

The approval of Tecentriq in these patients is based on a study that measured the amount of time until patients’ disease worsened. Continued approval for this use may depend on results of an ongoing study to confirm benefit.

A type of lung cancer called small cell lung cancer (SCLC).

• Tecentriq may be used with the chemotherapy medicines carboplatin and etoposide as your first treatment when your lung cancer:
  • is a type of lung cancer called “extensive-stage small cell lung cancer,” which means that it has spread or grown.

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

Important Safety Information

What is the most important information about Tecentriq?

Tecentriq can cause the immune system to attack normal organs and tissues and can affect the way they work. These problems can sometimes become serious or life threatening and can lead to death.

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

Tecentriq can cause serious side effects, including:

• Lung problems (pneumonitis)–signs and symptoms of pneumonitis may include new or worsening cough, shortness of breath, and chest pain
• Liver problems (hepatitis)–signs and symptoms of hepatitis may include yellowing of the skin or the whites of the eyes, severe nausea or vomiting, pain on the right side of the stomach area (abdomen), drowsiness, dark urine (tea colored), bleeding or bruising more easily than normal, and feeling less hungry than usual
• Intestinal problems (colitis)–signs and symptoms of colitis may include diarrhea (loose stools) or more bowel movements than usual, blood or mucus in stools or dark, tarry, sticky stools, and severe stomach area (abdomen) pain or tenderness
• Hormone gland problems (especially the thyroid, adrenal glands, pancreas, and pituitary)–signs and symptoms that the hormone glands are not working properly may include headaches that will not go away or unusual headaches, extreme tiredness, weight gain or weight loss, dizziness or fainting, feeling more hungry or thirsty than usual, hair loss, changes in mood or behavior (such as decreased sex drive, irritability, or forgetfulness), feeling cold, constipation, the voice gets deeper, urinating more often than usual, nausea or vomiting, and stomach area (abdomen) pain

Avastin is approved for:

• Metastatic colorectal cancer (mCRC) for first- or second-line treatment in combination with intravenous 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 surgery was used as the primary treatment in patients with colon cancer which 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.

• GI perforation. A hole that develops in the stomach or intestine. Symptoms include pain in the abdomen, nausea, vomiting, constipation, or fever
• 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
• 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
• 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-related 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, therefore women should not breastfeed during and for 6 months after taking Avastin

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