Genentech’s Tecentriq (Atezolizumab) Improves Overall Survival as a First-line Monotherapy in Certain People With Advanced Non-small Cell Lung Cancer

September 27, 2019 Off By BusinessWire

– Phase III IMpower110 study showed Tecentriq monotherapy helped people with advanced non-small cell lung cancer (NSCLC) with high PD-L1 expression live longer compared with chemotherapy alone –

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

SOUTH SAN FRANCISCO, Calif.–(BUSINESS WIRE)–Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced positive data from the Phase III IMpower110 study evaluating Tecentriq^® (atezolizumab) as a first-line (initial) monotherapy compared with cisplatin or carboplatin and pemetrexed or gemcitabine (chemotherapy) in advanced non-squamous and squamous non-small cell lung cancer (NSCLC) without ALK or EGFR mutations (wild-type; WT).

The study met its primary endpoint in an interim analysis showing that Tecentriq monotherapy improved overall survival (OS) by 7.1 months compared with chemotherapy alone (median OS=20.2 versus 13.1 months; hazard ratio [HR]=0.595, 95% CI: 0.398–0.890; p=0.0106) in people with high PD-L1 expression (TC3/IC3-WT). Encouraging OS (18.2 versus 14.9 months; HR=0.717, 95% CI: 0.520–0.989) was also observed in people with medium levels of PD-L1 expression (TC2/3 or IC2/3-WT), however these data did not reach statistical significance at this interim analysis. The study will continue to final analysis for people with lower levels of PD-L1 expression. Safety for Tecentriq appeared to be consistent with its known safety profile, and no new safety signals were identified.

“We are excited to share these positive data, showing that Tecentriq alone offers a significant survival benefit over chemotherapy as an initial treatment in people with squamous or non-squamous non-small cell lung cancer with high PD-L1 expression,” said Sandra Horning, M.D., chief medical officer and head of Global Product Development. “The IMpower110 results demonstrate the potential of first-line Tecentriq monotherapy in certain types of advanced lung cancer, and could provide an additional treatment option for oncologists and the patients that they treat.”

These data will be presented at the European Society for Medical Oncology (ESMO) 2019 Congress on Friday, September 27, 2019 from 4:00 – 5:30 p.m. CEST (Abstract LBA78; Barcelona Auditorium – Hall 2).

Genentech will submit these data to global health authorities, including the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA), and will discuss how best to bring this option to patients as quickly as possible.

Currently, Genentech has nine Phase III lung cancer studies underway evaluating Tecentriq as a monotherapy or in combination with other medicines across different types of lung cancer. Genentech has an extensive development program for Tecentriq, including multiple ongoing and planned Phase III studies, across 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 IMpower110 study

IMpower110 is a Phase III, randomized, open-label study to evaluate the efficacy and safety of Tecentriq monotherapy compared with cisplatin or carboplatin and pemetrexed or gemcitabine (chemotherapy) in programmed death-ligand 1 (PD-L1)-selected, chemotherapy-naive participants with advanced non-squamous or squamous NSCLC without ALK or EGFR mutations (wild-type; WT).

A total of 572 people (555 WT) were enrolled and were randomized 1:1 to receive:

Tecentriq monotherapy, until loss of clinical benefit (as assessed by the investigator), unacceptable toxicity or death; or
Cisplatin or carboplatin (per investigator discretion) combined with either pemetrexed (non-squamous) or gemcitabine (squamous), followed by maintenance therapy with pemetrexed alone (non-squamous) or best supportive care (squamous) until disease progression, unacceptable toxicity or death.

The primary efficacy endpoint is OS by PD-L1 subgroup (TC3/IC3-WT; TC2/3/IC2/3-WT; and TC1,2,3/IC1,2,3-WT), as determined by the SP142 assay test. Key secondary endpoints include investigator-assessed progression-free survival (PFS), objective response rate (ORR) and duration of response (DoR).

An overview of the key OS results is below:

	Median OS
	Arm A (Tecentriq)		Arm B (chemo)		HR^a95% CI	P Value
	n	months	n	months	HR^a95% CI	P Value
TC3 or IC3-WT	107	20.2	98	13.1	0.595 (0.398, 0.890)	0.0106
TC2/3 or IC2/3-WT*	166	18.2	162	14.9	0.717 (0.520, 0.989)	0.0416
TC1/2/3 or IC1/2/3-WT**	277	17.5	277	14.1	0.832 (0.649, 1.067)	0.1481^b

TC, tumor cell; IC, tumor-infiltrating immune cells. PD-L1 expression was centrally evaluated with the VENTANA SP142 IHC assay. TC3 or IC3 = TC ≥ 50% or IC ≥ 10% PD-L1+; TC1/2/3 or IC1/2/3 = TC ≥ 1% or IC ≥ 1% PD-L1+; TC2/3 or IC2/3 = TC ≥ 5% or IC ≥ 5% PD-L1+. ^aStratified. ^bOnly for descriptive purpose.

*TC2/3 or IC2/3-WT did not cross the pre-specified boundary for statistical significance

**TC1/2/3 or IC1/2/3-WT was not formally tested and did not meet statistical significance

The safety population comprised 286 patients in Arm A and 263 in Arm B. Treatment-related AEs (TRAEs) and Grade 3-4 TRAEs occurred in 60.5% (Arm A) and 85.2% (Arm B), and 12.9% (Arm A) and 44.1% (Arm B), respectively.

About lung cancer

According to the American Cancer Society, it is estimated that more than 228,000 Americans will be diagnosed with lung cancer in 2019, and NSCLC accounts for 80-85% of all lung cancers. It is estimated that approximately 60% 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. Indications

Tecentriq is a prescription medicine used to treat adults with:

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 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.
