On September 24, 2018 Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), reported results from the Phase III IMpower132 study of TECENTRIQ (atezolizumab) plus pemetrexed and platinum-based chemotherapy (cisplatin or carboplatin) for the initial (first-line) treatment of people with non-squamous, non-small cell lung cancer (NSCLC) (Press release, Genentech, SEP 24, 2018, View Source [SID1234529536]). This interim analysis showed that TECENTRIQ and chemotherapy reduced the risk of disease worsening or death (progression-free survival, PFS) by 40 percent compared with chemotherapy alone (PFS=7.6 versus 5.2 months; hazard ratio [HR] = 0.60, 95 percent CI: 0.49-0.72; p<0.0001). While a numerical improvement of 4.5 months for the co-primary endpoint of overall survival (OS) was observed, at this interim analysis statistical significance has not yet been met (median OS=18.1 versus 13.6 months; HR=0.81, 95 percent CI: 0.64-1.03; p=0.0797). 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.

"This is our third Phase III trial in non-squamous non-small cell lung cancer demonstrating that a TECENTRIQ-based regimen can help reduce the risk of disease progression for people living with this disease," said Sandra Horning, M.D., chief medical officer and head of Global Product Development. "We will discuss these results with health authorities globally."
Data will be presented at the International Association for the Study of Lung Cancer (IASLC) 2018 World Conference on Lung Cancer (WCLC) on Monday, September 24 at 2:35 – 2:45 p.m. EDT (Abstract OA05.07 Oral) and featured in the official WCLC press conference at 9:45 – 10:30 a.m. EDT.
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 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.
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 53.6 percent of people receiving TECENTRIQ plus chemotherapy compared to 39.1 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, 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), 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
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

Severe infusion reactions–signs and symptoms of infusion reactions may include chills or shaking, itching or rash, flushing, shortness of breath or wheezing, swelling of the face or lips, dizziness, fever, feeling like passing out, and back or neck pain
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. If patients 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.
are breastfeeding or plan to breastfeed. It is not known if TECENTRIQ passes into the breast milk. Do not breastfeed during treatment and for at least 5 months after the last dose of TECENTRIQ
Patients should tell their healthcare provider about all the medicines they take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
The most common side effects of TECENTRIQ in people with urothelial carcinoma include:
feeling tired
decreased appetite
nausea
constipation
urinary tract infection
diarrhea
fever
The most common side effects of TECENTRIQ in people with non-small cell lung cancer include:
feeling tired
decreased appetite
muscle pain
cough
shortness of breath
TECENTRIQ may cause fertility problems in females, which may affect the ability to have children. Patients should talk to their healthcare provider if they have concerns about fertility.
These are not all the possible side effects of TECENTRIQ. Patients should ask their healthcare provider or pharmacist for more information. Patients should call their doctor for medical advice about side effects.
