FDA Grants Priority Review to Genentech’s Tecentriq in Combination with Chemotherapy for the Initial Treatment of Extensive-Stage Small Cell Lung Cancer
Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the U.S. Food and Drug Administration (FDA) has accepted the company’s supplemental Biologics License Application (sBLA) and granted Priority Review for Tecentriq® (atezolizumab), in combination with carboplatin and etoposide (chemotherapy), for the initial (first-line) treatment of people with extensive-stage small cell lung cancer (ES-SCLC). The FDA is expected to make a decision on approval by March 18, 2019. A Priority Review designation is granted to medicines that the FDA has determined to have the potential to provide significant improvements in the treatment, prevention or diagnosis of a serious disease.
“It’s been more than 20 years since there has been a new initial treatment option for extensive-stage small cell lung cancer that delivers a clinically meaningful survival benefit,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “We are working closely with the FDA to bring this Tecentriq-based regimen to people with this difficult-to-treat type of lung cancer as soon as possible.”
This sBLA is based on results from the Phase III IMpower133 study, which met its co-primary endpoints of overall survival (OS) and progression-free survival (PFS) in the initial treatment of people with ES-SCLC. The safety profile of the combination was consistent with the safety profiles of the individual medicines, and no new safety signals were identified.
Tecentriq is currently approved by the FDA to treat people with metastatic non-small cell lung cancer (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 ALK or EGFR gene abnormalities.
About the IMpower133 study
IMpower133 is a Phase III, multicenter, double-blinded, randomized placebo-controlled study evaluating the efficacy and safety of Tecentriq in combination with chemotherapy (carboplatin and etoposide) versus chemotherapy (carboplatin and etoposide) alone in chemotherapy-naïve people with ES-SCLC. The study enrolled 403 people who were randomized equally (1:1) to receive:
- Tecentriq in combination with carboplatin and etoposide (Arm A), or
- Placebo in combination with carboplatin and etoposide (Arm B, control arm)
During the treatment-induction phase, people received treatment on 21-day cycles for four cycles, followed by maintenance with Tecentriq or placebo until progressive disease (PD) as assessed by the investigator using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1). Treatment could be continued until persistent radiographic PD or symptomatic deterioration was observed.
The co-primary endpoints were:
- PFS as determined by the investigator using RECIST v1.1 in the intention-to-treat (ITT) population
- OS in the ITT population
IMpower133 met its OS and PFS co-primary endpoints as per the study protocol. The analysis showed that Tecentriq and chemotherapy helped people live significantly longer compared to chemotherapy alone (OS=12.3 versus 10.3 months; hazard ratio [HR] = 0.70, 95 percent CI: 0.54-0.91; p=0.0069) in the ITT population. The one-year OS rate for people who received the Tecentriq-based combination was 51.7 percent compared to 38.2 percent for people who received chemotherapy alone. The Tecentriq-based combination also significantly reduced the risk of disease worsening or death compared to chemotherapy alone (PFS=5.2 versus 4.3 months; HR=0.77; 95 percent CI: 0.62-0.96; p=0.017). The one-year PFS rate for people who received the Tecentriq-based combination was 12.6 percent compared to 5.4 percent for people who received chemotherapy alone. 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. Grade 3-4 treatment-related adverse events (AEs) were reported in 56.6 percent of people receiving Tecentriq plus chemotherapy compared to 56.1 percent of people receiving chemotherapy alone.
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. Lung cancer can be broadly divided into two major types: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). NSCLC is the most prevalent type, accounting for around 85 percent of all lung cancer cases, and SCLC accounting for approximately 15 percent of all cases. The majority (approximately 70 percent) of people with SCLC are diagnosed with ES-SCLC.
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), as determined by an FDA-approved test, 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
