Genentech’s Phase 3 Study Study of its Lung Cancer Combo Met Co-Primary Endpoint of PFS

SOUTH SAN FRANCISCO, Calif.–(BUSINESS WIRE)–Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the Phase III IMpower132 study met its co-primary endpoint of progression-free survival (PFS) and demonstrated that the combination of TECENTRIQ® (atezolizumab) plus chemotherapy (cisplatin or carboplatin plus pemetrexed) reduced the risk of disease worsening or death (PFS) compared to chemotherapy alone in the initial (first-line) treatment of advanced non-squamous non-small cell lung cancer (NSCLC). While a numerical improvement for the co-primary endpoint of overall survival (OS) was observed, statistical significance was not met at this interim analysis, and the study will continue as planned with final OS results expected next year. Safety for the TECENTRIQ and chemotherapy combination appeared consistent with the known safety profile of the individual medicines, and no new safety signals were identified with the combination. These data will be presented at an upcoming medical meeting.

“The IMpower132 study showed TECENTRIQ plus chemotherapy prolonged the time people with this type of advanced lung cancer lived without their disease worsening. We will discuss these results with health authorities,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development.

About the IMpower132 study

IMpower132 is a Phase III, open-label, randomized study evaluating the efficacy and safety of TECENTRIQ plus chemotherapy (cisplatin or carboplatin and pemetrexed) versus chemotherapy alone in chemotherapy-naïve patients with advanced non-squamous NSCLC. The study enrolled 578 people who were randomized equally (1:1) to receive:

  • TECENTRIQ in combination with cisplatin or carboplatin and pemetrexed (Arm A), or
  • Cisplatin or carboplatin and pemetrexed (Arm B, control arm)

During the treatment-induction phase, people received TECENTRIQ, pemetrexed and investigator’s choice of either cisplatin or carboplatin on Day 1 of every three weeks for a dosing period of four or six cycles. People who experienced clinical benefit during the induction phase began maintenance therapy until disease progression.

The co-primary endpoints were:

  • PFS as determined by the investigator using RECIST v1.1
  • OS

IMpower132 met its PFS co-primary endpoint as per the study protocol.

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.

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 PD-L1 status 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 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.

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 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 mucous in the 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
  • Problems in other organs–signs and symptoms may include severe muscle weakness, numbness or tingling in hands or feet, confusion, blurry vision, double vision, or other vision problems, changes in mood or behavior, extreme sensitivity to light, neck stiffness, eye pain or redness, skin blisters or peeling, chest pain, irregular heartbeat, shortness of breath, or swelling of the ankles
