BRAFTOVI^® + MEKTOVI^® Significantly Improves Objective Response Rates in Metastatic Non-Small Cell Lung Cancer

• Results from the registrational PHAROS study presented at ASCO 2023 and published in the Journal of Clinical Oncology

NEW YORK, NY, June 4, 2023 – Pfizer Inc. (NYSE: PFE) announced today the first detailed results from the Phase 2 PHAROS study, which is evaluating the efficacy and safety of BRAFTOVI^® (encorafenib) given in combination with MEKTOVI^® (binimetinib) to patients with BRAF V600E-mutant metastatic non-small cell lung cancer (NSCLC).
 
The objective response rate (ORR) was 75% (95% CI: 62, 85) in treatment-naïve patients (n=59), and almost two-thirds (59%) of them maintained a response for at least 12 months. For previously treated patients (n=39), the ORR was 46% (95% CI: 30, 63), with one-third (33%) maintaining a response for at least 12 months. Median progression-free survival (PFS) was not estimable (NE) at data cutoff for the treatment-naïve group (95% CI: 15.7, NE) and 9.3 months (95% CI: 6.2, NE) for the previously treated group. Median overall survival (OS) was NE for either subgroup at the time of data cutoff.

These findings were simultaneously published in the Journal of Clinical Oncology (JCO) and presented during the poster discussion session “Lung Cancer — Non-Small Cell Metastatic” at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago on June 4 (abstract 9018).

“For more than a decade, Pfizer has been at the forefront of delivering personalized, biomarker-driven treatment options that have improved outcomes for patients with cancer,” said Chris Boshoff, M.D., Ph.D., Chief Development Officer, Oncology and Rare Disease, Pfizer Global Product Development. “Lung cancer – the number one cause of cancer death worldwide – remains an area of critical unmet need. We are pleased about these encouraging results from the PHAROS trial and excited by the potential of BRAFTOVI + MEKTOVI to benefit people living with BRAF V600E-mutant metastatic non-small cell lung cancer.” 

The ongoing, single-arm, open-label, multicenter Phase 2 PHAROS trial (NCT03915951) has enrolled a total of 98 patients with BRAF V600E-mutant metastatic NSCLC, all of whom received BRAFTOVI + MEKTOVI. The primary endpoint was confirmed ORR, assessed by independent radiology review (IRR). Secondary endpoints include duration of response, disease control rate, PFS, and time to response – all assessed by IRR – as well as OS and safety. 

A majority of adverse events (AEs) observed in the PHAROS trial were Grade 1 or 2 in severity. The most common treatment-related AEs (TRAEs) were nausea (50%), diarrhea (43%), and fatigue (32%). TRAEs led to dose reductions in 24 (24%) patients and permanent treatment discontinuation in 15 (15%) patients. One Grade 5 TRAE of intracranial hemorrhage was reported. The safety profile from PHAROS is consistent with that observed in the approved melanoma indication.

“BRAF V600E-mutant metastatic non-small cell lung cancer tends to be aggressive and resistant to chemotherapy.²  In the PHAROS trial, we saw that targeted combination therapy with BRAFTOVI + MEKTOVI provided a clinical benefit to these patients, regardless of prior treatment, while maintaining a manageable safety profile,” said PHAROS investigator Gregory Riely, M.D., Ph.D., Vice Chair, Clinical Research in the Department of Medicine at Memorial Sloan Kettering Cancer Center (MSK). “If approved, BRAFTOVI + MEKTOVI could become an important new treatment choice for patients with BRAF V600E-mutant metastatic non-small cell lung cancer, where effective new options with manageable safety profiles are needed.”

In April 2023, Pfizer announced that the U.S. Food and Drug Administration (FDA) is reviewing the company’s Supplemental New Drug Applications (sNDAs) for BRAFTOVI + MEKTOVI for patients with metastatic NSCLC with a BRAF V600E mutation, as detected by an FDA-approved test. These sNDAs are supported by results from the PHAROS trial. The Prescription Drug User Fee Act (PDUFA) goal date for a decision by the FDA is in Fourth-Quarter 2023. 

In the U.S., BRAFTOVI + MEKTOVI is currently approved for the treatment of patients with unresectable or metastatic melanoma with a BRAF V600E or V600K mutation, as detected by an FDA-approved test. BRAFTOVI is also approved, in combination with cetuximab, for the treatment of adult patients with metastatic colorectal cancer (CRC) with a BRAF V600E mutation, as detected by an FDA-approved test, after prior therapy.

About PHAROS 
PHAROS (NCT03915951) is an ongoing, open-label, multicenter, non-randomized Phase 2 study to determine the efficacy and safety of BRAFTOVI + MEKTOVI in 98 patients with BRAF V600E-mutant metastatic NSCLC. Mutations were identified using next-generation sequencing or polymerase chain reaction tests performed at the patient’s local laboratory. The primary endpoint is ORR, based on IRR (per RECIST v1.1); secondary objectives include additional efficacy endpoints and safety. Duration of response is a key secondary endpoint. The trial is being conducted in 56 sites across Italy, the Netherlands, South Korea, Spain, and the U.S.

The PHAROS trial is being conducted with support from Pierre Fabre.

About BRAF V600E-mutant Non-Small Cell Lung Cancer (NSCLC)
Lung cancer is the second most common type of cancer and the number one cause of cancer-related death around the world.¹ NSCLC accounts for approximately 80-85% of all lung cancers.³
 
Certain lung cancers are linked to acquired genetic abnormalities like a BRAF V600E mutation. By using biomarkers to identify a person’s particular tumor type, treatment can become more personalized and effective, since the molecular makeup of a person’s cancer often determines how they respond to different therapies. 

A BRAF V600E mutation occurs in approximately 2% of NSCLC cases.⁴ It stimulates tumor cell growth and proliferation by altering the MAP kinase (MAPK) signaling pathway. Targeting components of this pathway could potentially inhibit unchecked tumor growth and proliferation caused by BRAF mutations.⁵
 
Precision medicine is increasingly being developed for NSCLC patients with genetic changes, such as BRAF mutations, that can be detected using biomarker tests.^6,7 Advances in targeted therapy and more widespread use of biomarker testing have been associated with significant improvements in population-level NSCLC mortality in recent years.⁸

About BRAFTOVI + MEKTOVI 
BRAFTOVI is an oral small molecule BRAF kinase inhibitor and MEKTOVI is an oral small molecule MEK inhibitor, both of which target key proteins in the MAPK signaling pathway (RAS-RAF-MEK-ERK). Inappropriate activation of this pathway has been shown to occur in many cancers, including melanoma, CRC, and NSCLC. 

In 2018, the FDA approved BRAFTOVI + MEKTOVI in combination for patients with unresectable or metastatic melanoma with a BRAF V600E or V600K mutation, as detected by an FDA-approved test. The approval was based on results from the randomized, active-controlled, open-label, multicenter Phase 3 COLUMBUS trial. 

In 2020, BRAFTOVI was FDA-approved, in combination with cetuximab, for the treatment of adults with metastatic CRC with a BRAF V600E mutation, as detected by an FDA-approved test, after prior therapy. The approval was based on results from the randomized, active-controlled, open-label, multicenter Phase 3 BEACON CRC trial.

Pfizer has exclusive rights to BRAFTOVI and MEKTOVI in the U.S., Canada, and all countries in the Latin American, African, and Middle Eastern regions. Ono Pharmaceutical Co., Ltd. has exclusive rights to commercialize both products in Japan and South Korea, Medison has exclusive rights in Israel, and Pierre Fabre has exclusive rights in all other countries, including Europe and Asia-Pacific (excluding Japan and South Korea).
