NEW YORK--( BUSINESS WIRE )-- Pfizer Inc. (NYSE: PFE) today announced positive results from the Phase 3 BREAKWATER trial evaluating BRAFTOVI ® (encorafenib) in combination with cetuximab (marketed as ERBITUX ® ) and mFOLFOX6 (fluorouracil, leucovorin, and oxaliplatin) in patients with metastatic colorectal cancer (mCRC) with a BRAF V600E mutation. At the time of this analysis, the BRAFTOVI combination regimen demonstrated a clinically meaningful and statistically significant improvement in confirmed objective response rate (ORR) assessed by blinded independent central review (BICR) compared to patients receiving chemotherapy with or without bevacizumab (60.9% vs 40.0%, odds ratio =2.443, p=0.0008). These results will be presented today in an oral presentation (Abstract 16) at the 2025 American Society of Clinical Oncology Gastrointestinal Cancer Symposium (ASCO GI) and were simultaneously published in Nature Medicine . “ Despite the high unmet need in this patient population, prior to the recent encorafenib combination regimen approval, there were no approved biomarker-driven therapies indicated for people with previously untreated BRAF V600E -mutant metastatic colorectal cancer,” said Scott Kopetz, M.D., Ph.D., FACP, Professor and Deputy Chair of Gastrointestinal Medical Oncology at The University of Texas MD Anderson Cancer Center and co-principal investigator of the BREAKWATER trial. “ These data from the BREAKWATER study show the potential for this targeted treatment regimen to become the new standard of care for people with BRAF V600E -mutant metastatic colorectal cancer, for whom long-term disease control is critical.” The estimated median duration of response as assessed by BICR was 13.9 months (95% Confidence Interval [CI]: 8.5-not estimable [NE]) with BRAFTOVI plus cetuximab and mFOLFOX6 and 11.1 months (95% CI: 6.7-12.7) with chemotherapy with or without bevacizumab. Of patients on BRAFTOVI plus cetuximab and mFOLFOX6, 22.4% (n=15) had a response lasting 12 months or longer, compared to 11.4% (n=5) with chemotherapy with or without bevacizumab. The median time to response as assessed by BICR was 7.1 weeks (range 5.7-53.7) with BRAFTOVI plus cetuximab and mFOLFOX6 and 7.3 weeks (range 5.4-48.0) with chemotherapy with or without bevacizumab. Overall survival (OS) data were immature at the time of this analysis but demonstrated a promising trend in favor of BRAFTOVI plus cetuximab and mFOLFOX6 compared to patients receiving chemotherapy with or without bevacizumab. Median OS with BRAFTOVI plus cetuximab with chemotherapy was not estimable (95% CI: 19.8-NE) and 14.6 months (95% CI: 13.4-NE) with chemotherapy with or without bevacizumab (Hazard Ratio [HR]: 0.47, 95% CI: 0.318-0.691). The BREAKWATER trial is ongoing for OS and progression-free survival (PFS), with PFS results expected in 2025. “ These results of this first analysis were the basis for the first approval of a targeted therapy regimen for use in the first-line setting for patients with metastatic colorectal cancer with a BRAF V600E mutation,” said Roger Dansey, M.D., Chief Oncology Officer, Pfizer. “ We are highly encouraged by these response results, which are indicative of the clinically meaningful benefit of BRAFTOVI in reducing tumor size or having no detectable cancer, along with the promising interim analysis of overall survival. We look forward to additional read-outs from the BREAKWATER trial this year.” The safety profile of BRAFTOVI in combination with cetuximab and mFOLFOX6 in the BREAKWATER trial was consistent with the known safety profile of each respective agent. No new safety signals were identified. Serious treatment-emergent adverse events occurred in 37.7% of patients receiving BRAFTOVI in combination with cetuximab and mFOLFOX6 compared to 34.6% of patients receiving chemotherapy with or without bevacizumab. BRAFTOVI in combination with cetuximab and mFOLFOX6 was granted accelerated approval by the U.S. Food and Drug Administration (FDA) for the treatment of patients with BRAF V600E -mutant mCRC in December 2024. The approval was among the first in the industry to be conducted under the FDA’s Project FrontRunner, which seeks to support the development and approval of new cancer drugs for advanced or metastatic disease. The BREAKWATER data are also being discussed with other regulatory authorities around the world to support potential future additional license applications for the BRAFTOVI combination regimen in this indication. Pfizer is continuing its commitment to help non-scientists understand the latest findings with the development of abstract plain language summaries (APLS) for company-sponsored research being presented, which are written in non-technical language. Those interested in learning more can visit www.Pfizer.com/apls to access the summaries. About BREAKWATER BREAKWATER is a Phase 3, randomized, active-controlled, open-label, multicenter trial of BRAFTOVI with cetuximab, alone or in combination with mFOLFOX6 in participants with previously untreated BRAF V600E-mutant mCRC. Patients were randomized to receive BRAFTOVI 300 mg orally once daily in combination with cetuximab (discontinued after randomization of 158 patients), BRAFTOVI 300 mg orally once daily in combination with cetuximab and mFOLFOX6 (n=236) or mFOLFOX6, FOLFOXIRI, or CAPOX each with or without bevacizumab (control-arm) (n=243). The dual primary endpoints are ORR, which was met at the time of analysis, and PFS as assessed by BICR. OS is a key secondary endpoint. About Colorectal Cancer (CRC) CRC is the third most common type of cancer in the world, with approximately 1.8 million new diagnoses in 2022. 1 It is the second leading cause of cancer-related deaths. 2 Overall, the lifetime risk of developing CRC is about 1 in 24 for men and 1 in 26 for women. 2 In the U.S. alone, an estimated 154,270 people will be diagnosed with cancer of the colon or rectum in 2025, and approximately 53,000 are estimated to die from the disease each year. 3 For 20% of those diagnosed with CRC, the disease has metastasized, or spread, making it harder to treat, and up to 50% of patients with localized disease eventually develop metastases. 4 BRAF mutations are estimated to occur in 8-12% of people with mCRC and represent a poor prognosis for these patients. 5 The BRAF V600E mutation is the most common BRAF mutation and the risk of mortality in CRC patients with the BRAF V600E mutation is more than double that of patients with no known mutation present. 5,6 Despite the high unmet need in BRAF V600E -mutant mCRC, prior to December 20, 2024, there were no approved biomarker-driven therapies specifically indicated for people with previously untreated BRAF V600E -mutant mCRC. 7,8 About BRAFTOVI ® (encorafenib) BRAFTOVI is an oral small molecule kinase inhibitor that targets BRAF V600E . Inappropriate activation of proteins in the MAPK signaling pathway (RAS-RAF-MEK-ERK) has been shown to occur in certain cancers, including CRC. Pfizer has exclusive rights to BRAFTOVI in the U.S., Canada, Latin America, Middle East, and Africa. Ono Pharmaceutical Co., Ltd. has exclusive rights to commercialize the product in Japan and South Korea, Medison has exclusive rights to commercialize the product in Israel and Pierre Fabre Laboratories has exclusive rights to commercialize the product in all other countries, including Europe and Asia (excluding Japan and South Korea). INDICATION AND USAGE BRAFTOVI ® (encorafenib) is indicated, in combination with cetuximab and mFOLFOX6, for the treatment of patients with metastatic colorectal cancer (mCRC) with a BRAF V600E mutation, as detected by an FDA-approved test. This indication is approved under accelerated approval based on response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s). BRAFTOVI is also indicated, in combination with cetuximab, for the treatment of adult patients with mCRC with a BRAF V600E mutation, as detected by an FDA-approved test, after prior therapy. Limitations of Use : BRAFTOVI is not indicated for treatment of patients with wild-type BRAF CRC. IMPORTANT SAFETY INFORMATION Refer to the prescribing information for cetuximab and individual product components of mFOLFOX6 for recommended dosing and additional safety information. WARNINGS AND PRECAUTIONS New Primary Malignancies: New primary malignancies, cutaneous and non-cutaneous, can occur. In BEACON CRC (previously treated BRAF V600E mutation-positive mCRC), cutaneous squamous cell carcinoma (cuSCC), including keratoacanthoma (KA), occurred in 1.4% of patients with CRC, and a new primary melanoma occurred in 1.4% of patients who received BRAFTOVI in combination with cetuximab. In BREAKWATER (previously untreated BRAF V600E mutation-positive mCRC) skin papilloma was reported in 2.6%, basal cell carcinoma in 1.3%, squamous cell carcinoma of skin in 0.9%, keratoacanthoma in 0.4% and malignant melanoma in situ in 0.4% of patients who received BRAFTOVI in combination with cetuximab and mFOLFOX6. Perform dermatologic evaluations prior to initiating treatment, every 2 months during treatment, and for up to 6 months following discontinuation of treatment. Manage suspicious skin lesions with excision and dermatopathologic evaluation. Dose modification is not recommended for new primary cutaneous malignancies. Based on its mechanism of action, BRAFTOVI may promote malignancies associated with activation of RAS through mutation or other mechanisms. Monitor patients receiving BRAFTOVI for signs and symptoms of non-cutaneous malignancies. Discontinue BRAFTOVI for RAS mutation-positive non-cutaneous malignancies. Monitor patients for new malignancies prior to initiation of treatment, while on treatment, and after discontinuation of treatment. Tumor Promotion in BRAF Wild-Type Tumors: In vitro experiments have demonstrated paradoxical activation of MAP-kinase signaling and increased cell proliferation in BRAF wild-type cells exposed to BRAF inhibitors. Confirm evidence of BRAF V600E or V600K mutation using an FDA-approved test prior to initiating BRAFTOVI. Cardiomyopathy: Cardiomyopathy manifesting as left ventricular dysfunction associated with symptomatic or asymptomatic decreases in ejection fraction, has been reported in patients. Assess left ventricular ejection fraction (LVEF) by echocardiogram or multi-gated acquisition (MUGA) scan prior to initiating treatment, 1 month after initiating treatment, and then every 2 to 3 months during treatment. The safety has not been established in patients with a baseline ejection fraction that is either below 50% or below the institutional lower limit of normal (LLN). Patients with cardiovascular risk factors should be monitored closely. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction. Hepatotoxicity: Hepatotoxicity can occur. In BREAKWATER (previously untreated BRAF V600E mutation-positive mCRC), the incidence of Grade 3 or 4 increases in liver function laboratory tests in patients receiving BRAFTOVI in combination with cetuximab and mFOLFOX6 was 2.2% for alkaline phosphatase, 1.3% for ALT, and 0.9% for AST. Monitor liver laboratory tests before initiation of BRAFTOVI, monthly during treatment, and as clinically indicated. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction. Hemorrhage: In BEACON CRC (previously treated BRAF V600E mutation-positive mCRC), hemorrhage occurred in 19% of patients receiving BRAFTOVI in combination with cetuximab; Grade 3 or higher hemorrhage occurred in 1.9% of patients, including fatal gastrointestinal hemorrhage in 0.5% of patients. The most frequent hemorrhagic events were epistaxis (6.9%), hematochezia (2.3%), and rectal hemorrhage (2.3%). In BREAKWATER (previously untreated BRAF V600E mutation-positive mCRC), hemorrhage occurred in 30% of patients receiving BRAFTOVI in combination with cetuximab and mFOLFOX6; Grade 3 or 4 hemorrhage occurred in 3% of patients. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction. Uveitis: Uveitis, including iritis and iridocyclitis, has been reported in patients treated with BRAFTOVI. Assess for visual symptoms at each visit. Perform an ophthalmological evaluation at regular intervals and for new or worsening visual disturbances, and to follow new or persistent ophthalmologic findings. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction. QT Prolongation: BRAFTOVI is associated with dose-dependent QTc interval prolongation in some patients. In BREAKWATER (previously untreated BRAF V600E mutation-positive mCRC), an increase of QTcF >500 ms was measured in 3.6% (8/222) of patients receiving BRAFTOVI in combination with cetuximab and mFOLFOX6. Monitor patients who already have or who are at significant risk of developing QTc prolongation, including patients with known long QT syndromes, clinically significant bradyarrhythmias, severe or uncontrolled heart failure and those taking other medicinal products associated with QT prolongation. Correct hypokalemia and hypomagnesemia prior to and during BRAFTOVI administration. Withhold, reduce dose, or permanently discontinue for QTc >500 ms. Embryo-Fetal Toxicity: BRAFTOVI can cause fetal harm when administered to pregnant women. BRAFTOVI can render hormonal contraceptives ineffective. Advise females of reproductive potential to use effective nonhormonal contraception during treatment with BRAFTOVI and for 2 weeks after the final dose. Risks Associated with Combination Treatment: BRAFTOVI is indicated for use as part of a regimen in combination with cetuximab, or in combination with cetuximab and mFOLFOX6. Refer to the prescribing information for cetuximab and individual product components of mFOLFOX6 for additional risk information. Lactation: Advise women not to breastfeed during treatment with BRAFTOVI and for 2 weeks after the final dose. Infertility: Advise males of reproductive potential that BRAFTOVI may impair fertility. ADVERSE REACTIONS BREAKWATER Trial (previously untreated BRAF V600E mutation-positive mCRC) Serious adverse reactions occurred in 38% of patients who received BRAFTOVI in combination with cetuximab and mFOLFOX6. Serious adverse reactions in >3% of patients included intestinal obstruction (3.5%) and pyrexia (3.5%). Fatal gastrointestinal perforation occurred in 0.9% of patients who received BRAFTOVI in combination with cetuximab and mFOLFOX6. Most common adverse reactions (≥25%, all grades) in the BRAFTOVI with cetuximab and mFOLFOX6 arm compared to the control arm (mFOLFOX6 ± bevacizumab or FOLFOXIRI ± bevacizumab or CAPOX ± bevacizumab) were peripheral neuropathy (62% vs 53%), nausea (51% vs 48%), fatigue (49% vs 38%), rash (31% vs 4%), diarrhea (34% vs 47%), decreased appetite (33% vs 25%), vomiting (33% vs 21%), hemorrhage (30% vs 18%), abdominal pain (26% vs 27%), and pyrexia (26% vs 14%). Most common laboratory abnormalities (≥10%, grade 3 or 4) in the BRAFTOVI with cetuximab and mFOLFOX6 arm compared to the control arm (mFOLFOX6 ± bevacizumab or FOLFOXIRI ± bevacizumab or CAPOX ± bevacizumab) were: increased lipase (51% vs 25%), decreased neutrophil count (36% vs 34%), decreased hemoglobin (13% vs 5%), decreased white blood cell count (12% vs 7%), and increased glucose (11% vs 2%). BEACON CRC Trial (previously treated BRAF V600E mutation-positive mCRC) Most common adverse reactions (≥25%, all grades) in the BRAFTOVI with cetuximab arm compared to irinotecan with cetuximab or FOLFIRI with cetuximab (control) were: fatigue (51% vs 50%), nausea (34% vs 41%), diarrhea (33% vs 48%), dermatitis acneiform (32% vs 43%), abdominal pain (30% vs 32%), decreased appetite (27% vs 27%), arthralgia (27% vs 3%), and rash (26% vs 26%). Other clinically important adverse reactions occurring in <10% of patients who received BRAFTOVI in combination with cetuximab was pancreatitis. Most common laboratory abnormalities (all grades) (≥20%) in the BRAFTOVI with cetuximab arm compared to irinotecan with cetuximab or FOLFIRI with cetuximab (control) were: anemia (34% vs 48%) and lymphopenia (24% vs 35%). DRUG INTERACTIONS Strong or moderate CYP3A4 inhibitors: Avoid coadministration of BRAFTOVI with strong or moderate CYP3A4 inhibitors, including grapefruit juice. If coadministration is unavoidable, reduce the BRAFTOVI dose. Strong CYP3A4 inducers: Avoid coadministration of BRAFTOVI with strong CYP3A4 inducers. Sensitive CYP3A4 substrates: Avoid the coadministration of BRAFTOVI with CYP3A4 substrates (including hormonal contraceptives) for which a decrease in plasma concentration may lead to reduced efficacy of the substrate. If the coadministration cannot be avoided, see the CYP3A4 substrate product labeling for recommendations. Dose reductions of drugs that are substrates of OATP1B1, OATP1B3, or BCRP may be required when used concomitantly with BRAFTOVI.

NEW YORK--( BUSINESS WIRE )-- Pfizer Inc. (NYSE: PFE) today announced longer-term follow-up results from the Phase 2 single-arm PHAROS clinical trial evaluating the efficacy and safety of BRAFTOVI ® (encorafenib) in combination with MEKTOVI ® (binimetinib) for patients with BRAF V600E - mutant metastatic non-small cell lung cancer (NSCLC). After an additional 18 months of follow-up, the objective response rate (ORR) and the median duration of response (DoR) as assessed by independent radiology review were 75% and 40 months in treatment-naïve patients and 46% and 16.7 months in previously treated patients, respectively. In addition, after approximately three years of follow-up in treatment-naïve patients, the median progression-free survival (PFS) with BRAFTOVI + MEKTOVI was 30.2 months (95% confidence interval [CI], 15.7-not estimable [NE]), while median overall survival (OS) was not yet reached (95% CI, 31.3-NE). These data will be presented today during a late-breaking oral session (Abstract LBA56) at the European Society for Medical Oncology (ESMO) Congress 2024 in Barcelona, Spain. “ BRAF V600E-mutant metastatic non-small cell lung cancer tends to be aggressive, and effective targeted first-line treatment options with manageable safety profiles are critical for the thousands of people who are diagnosed globally each year,” said Gregory Riely, M.D., Ph.D., Vice Chair, Clinical Research in the Department of Medicine at Memorial Sloan Kettering Cancer Center (MSK) and PHAROS investigator. “ The longer-term follow-up results from the PHAROS trial represent an important step forward in the treatment of BRAF V600E-mutant metastatic NSCLC, especially for treatment-naïve patients. These compelling results support the BRAFTOVI + MEKTOVI combination as a standard of care option for these patients.” Lung cancer is the number one cause of cancer-related death around the world. 1 NSCLC accounts for approximately 80-85% of lung cancers, 2 with BRAF V600E mutations occurring in about 2% of patients with NSCLC. 3 Understanding the role of the mitogen-activated protein within the pathway including BRAF V600E-mutant metastatic NSCLC. The Phase 2 PHAROS trial ( NCT03915951 ) is an open-label, multicenter, single arm study examining BRAFTOVI + MEKTOVI combination therapy in treatment-naïve and previously treated patients with BRAF V600E-mutant metastatic NSCLC. Notably, upon longer-term follow-up in previously treated patients, BRAFTOVI + MEKTOVI showed a median PFS of 9.3 months (95% CI, 6.2-24.8) and a median OS of 22.7 months (95% CI, 14.1-32.2), with a safety profile that was consistent with previous findings; no new safety concerns were identified. In this analysis, treatment-related adverse events (AEs) led to dose reduction in 26% of patients, and to permanent discontinuation in 16% of patients. Nausea, diarrhea, and fatigue remained the most common treatment-related AEs. “ These potentially practice-changing results from the PHAROS trial show that the combination of BRAFTOVI + MEKTOVI is providing long-term compelling efficacy for patients, and although no definitive conclusions can be made across trials, the duration of response and progression-free survival in treatment naïve patients appear to be the longest observed for BRAF V600E–mutant metastatic NSCLC compared with historical outcomes,” said Roger Dansey, M.D., Chief Development Officer, Oncology, Pfizer. “ These latest data reflect our deep understanding of the science behind biomarker-driven cancers and add to our legacy in developing innovative targeted treatments in NSCLC. We are continuing to build upon this strong foundation with a pipeline of targeted medicines and combinations across our tumor areas of focus, including the ongoing investigation of BRAFTOVI in earlier settings of metastatic colorectal cancer, and the exploration of a next-generation brain-penetrant BRAF inhibitor.” BRAFTOVI + MEKTOVI was approved by the U.S. Food and Drug Administration (FDA) in October 2023, and by the European Commission in August 2024, for the treatment of BRAF V600E-mutant metastatic NSCLC based on the initial ORR (the primary endpoint) and DoR (key secondary endpoint) results from the PHAROS clinical trial. In addition to PHAROS, safety lead-in data from the ongoing Phase 3 BREAKWATER study investigating BRAFTOVI in combination with cetuximab and FOLFIRI chemotherapy in previously untreated BRAF V600E-mutant metastatic colorectal cancer (CRC) will also be presented as a mini-oral session at ESMO (Abstract 515MO). BRAFTOVI in combination with cetuximab and FOLFIRI was found to be generally tolerable in this patient population, with no new safety concerns identified. These findings support the ongoing investigation of this combination regimen as a potential treatment option for BRAF V600E-mutant metastatic CRC. The Phase 3 BREAKWATER trial is ongoing, with updated data expected in 2025. BRAF mutations can occur in a number of tumor types, including metastatic melanoma, metastatic CRC and metastatic NSCLC. Among different types of BRAF mutations, the BRAF V600E mutation is particularly important as it occurs in approximately half of patients with BRAF -mutant metastatic NSCLC. 4 Further, this mutation represents up to 90% of BRAF mutations in melanoma 5 and more than doubles the risk of mortality for patients with CRC. 6 In addition to our continued investigation of BRAFTOVI + MEKTOVI for BRAF- mutant cancers, Pfizer is also exploring a next-generation BRAF inhibitor designed to selectively inhibit mutant BRAF monomers and mutant BRAF- containing dimers and be brain penetrant. The investigational drug is currently being evaluated in a Phase 1 clinical study. Pfizer has exclusive rights to BRAFTOVI + MEKTOVI in the U.S., Canada, and all countries in Latin America, Africa and the Middle East. 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 Laboratories has exclusive rights in all other countries, including Europe and Asia-Pacific (excluding Japan and South Korea). The PHAROS trial is conducted with support from Pierre Fabre Laboratories. INDICATION AND USAGE BRAFTOVI ® (encorafenib) and MEKTOVI ® (binimetinib) are kinase inhibitors indicated for use in combination 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 indicated, 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. BRAFTOVI and MEKTOVI are kinase inhibitors indicated for use in combination for the treatment of adult patients with metastatic non-small cell lung cancer (NSCLC) with a BRAF V600E mutation, as detected by an FDA-approved test. Limitations of Use : BRAFTOVI is not indicated for treatment of patients with wild-type BRAF melanoma, wild-type BRAF CRC, or wild-type BRAF NSCLC. IMPORTANT SAFETY INFORMATION This information applies to the safety of BRAFTOVI when used in combination with either MEKTOVI or cetuximab. WARNINGS AND PRECAUTIONS New Primary Malignancies: New primary malignancies, cutaneous and non-cutaneous, can occur. BRAFTOVI may promote malignancies associated with activation of RAS through mutation or other mechanisms. Perform dermatopathologic evaluations prior to initiating treatment, every 2 months during treatment, and for up to 6 months following discontinuation of treatment. Manage suspicious skin lesions with excision and dermatopathologic evaluation. Dose modification is not recommended for new primary cutaneous malignancies. Monitor patients receiving BRAFTOVI for signs and symptoms of non-cutaneous malignancies. Discontinue BRAFTOVI for RAS mutation-positive non-cutaneous malignancies. Monitor patients for new malignancies prior to initiation of treatment, while on treatment, and after discontinuation of treatment. BRAF -mutant type ( BRAF -mt) metastatic melanoma (COLUMBUS study): Cutaneous squamous cell carcinoma (cuSCC), including keratoacanthoma (KA), occurred in 2.6% and basal cell carcinoma occurred in 1.6% of patients receiving BRAFTOVI with MEKTOVI. Median time to first occurrence of cuSCC/KA was 5.8 months. BRAF -mt metastatic CRC (BEACON CRC study): cuSCC, including KA, occurred in 1.4% of patients with CRC, and a new primary melanoma occurred in 1.4% of patients who received BRAFTOVI with cetuximab. BRAF -mt metastatic NSCLC (PHAROS study): cuSCC and skin papilloma (SP), each occurred in 2% of patients. Tumor Promotion in BRAF Wild-Type Tumors: In vitro experiments have demonstrated paradoxical activation of MAP-kinase signaling and increased cell proliferation in BRAF wild-type cells exposed to BRAF inhibitors. Confirm evidence of BRAF V600E or V600K mutation using an FDA-approved test prior to initiating BRAFTOVI. Cardiomyopathy: Cardiomyopathy manifesting as left ventricular dysfunction associated with symptomatic or asymptomatic decreases in ejection fraction, has been reported. Patients with cardiovascular risk factors should be monitored closely. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction.

BRAFTOVI + MEKTOVI now gives adult patients with BRAF V600E-mutant metastatic non-small cell lung cancer a new personalized treatment option NEW YORK--(BUSINESS WIRE)-- Pfizer Inc. (NYSE: PFE) announced today that the U.S. Food and Drug Administration (FDA) has approved BRAFTOVI® (encorafenib) + MEKTOVI® (binimetinib) for the treatment of adult patients with metastatic non-small cell lung cancer (NSCLC) with a BRAF V600E mutation, as detected by an FDA-approved test.1 BRAF V600E mutations can be assessed from either plasma or tumor tissue using the FoundationOne Liquid CDx or the FoundationOne CDx FDA-approved companion diagnostic tests, respectively. “Today’s approval builds on our long-standing commitment to deliver innovative, personalized medicines to patients with lung cancer. By pursuing precision medicines that target a patient’s specific type of cancer, we are leveraging our deep understanding of tumor biology to help address the underlying cause of disease,” said Chris Boshoff, M.D., Ph.D., Chief Oncology Research and Development Officer and Executive Vice President at Pfizer. “Since its initial FDA approval in 2018, BRAFTOVI + MEKTOVI combination therapy has helped thousands of people living with BRAF V600E- or V600K-mutant unresectable or metastatic melanoma.2 We look forward to helping even more patients with our BRAFTOVI + MEKTOVI targeted combination therapy.” The FDA’s approval is based on data from the ongoing Phase 2 PHAROS clinical trial (NCT03915951), an open-label, multicenter, single‑arm study examining BRAFTOVI + MEKTOVI combination therapy in both treatment-naïve and previously treated patients with BRAF V600E-mutant metastatic NSCLC. “BRAF V600E mutations identify a unique subtype of metastatic non-small cell lung cancer that presents an actionable biomarker that precision medicines like BRAFTOVI + MEKTOVI combination therapy can help address,” said Gregory Riely, M.D., Ph.D., Vice Chair, Clinical Research in the Department of Medicine at Memorial Sloan Kettering Cancer Center (MSK) and PHAROS investigator. “The PHAROS trial demonstrated that these patients could benefit from BRAFTOVI + MEKTOVI targeted therapy regardless of their prior treatment history. Given the specific efficacy and safety profile, patients and providers now have another option to help personalize treatment plans based on individual risk factors and preferences.” The PHAROS study met its major efficacy outcome measures of objective response rate (ORR), as assessed by independent review committee (IRC), and duration of response (DOR) in both treatment groups. For treatment-naïve patients (n=59), ORR was 75% (95% CI: 62, 85), and 59% of the patients responded for at least 12 months. Median DOR was not estimable (NE) for this group at the time of data cutoff. For previously treated patients (n=39), ORR was 46% (95% CI: 30, 63), and 33% of the patients responded for at least 12 months. Median DOR was 16.7 months (95% CI: 7.4, NE). These data were presented earlier this year at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting and simultaneously published in the Journal of Clinical Oncology (JCO).3 The most common (≥25%) all-causality adverse reactions observed in the PHAROS trial were fatigue, nausea, diarrhea, musculoskeletal pain, vomiting, abdominal pain, visual impairment, constipation, dyspnea, rash, and cough. A total of 17% of patients experienced an adverse reaction that resulted in permanent discontinuation of MEKTOVI and 16% experienced an adverse event that resulted in permanent discontinuation of BRAFTOVI. Serious adverse reactions occurred in 38% of patients. Serious adverse reactions occurring in ≥2% of patients included hemorrhage (6%), diarrhea (4.1%), anemia, dyspnea, pneumonia (3.1% each), arrhythmia, device-related infection, edema, myocardial infarction, and pleural effusion (2% each). Fatal adverse reactions occurred in 2% of patients, including intracranial hemorrhage and myocardial infarction (1% each). BRAFTOVI + MEKTOVI is also FDA-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 FDA-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. Pfizer has exclusive rights to BRAFTOVI and MEKTOVI in the U.S., Canada, and all countries in Latin America, Africa, and the Middle East. 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). The PHAROS trial is 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.4 NSCLC accounts for approximately 80-85% of all lung cancers.5 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.6 It stimulates tumor cell growth and proliferation by altering the MAP kinase (MAPK) signaling pathway. Targeting components of this pathway could potentially help inhibit tumor growth and proliferation caused by BRAF mutations.7 Precision medicine is increasingly being developed for NSCLC patients with genetic changes, such as BRAF mutations, that can be detected using biomarker tests.8,9 In recent years, more widespread use of biomarker testing and targeted therapies have been associated with improvements in population-level NSCLC mortality.10 INDICATIONS AND USAGE BRAFTOVI® (encorafenib) and MEKTOVI® (binimetinib) are kinase inhibitors indicated for use in combination 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 indicated, 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. BRAFTOVI and MEKTOVI are kinase inhibitors indicated for use in combination for the treatment of adult patients with metastatic non-small cell lung cancer (NSCLC) with a BRAF V600E mutation, as detected by an FDA-approved test. Limitations of Use: BRAFTOVI is not indicated for treatment of patients with wild-type BRAF melanoma, wild-type BRAF CRC, or wild-type BRAF NSCLC. IMPORTANT SAFETY INFORMATION This information applies to the safety of BRAFTOVI when used in combination with either MEKTOVI or cetuximab. WARNINGS AND PRECAUTIONS New Primary Malignancies: New primary malignancies, cutaneous and non-cutaneous, can occur. BRAFTOVI may promote malignancies associated with activation of RAS through mutation or other mechanisms. Perform dermatopathologic evaluations prior to initiating treatment, every 2 months during treatment, and for up to 6 months following discontinuation of treatment. Manage suspicious skin lesions with excision and dermatopathologic evaluation. Dose modification is not recommended for new primary cutaneous malignancies. Monitor patients receiving BRAFTOVI for signs and symptoms of non-cutaneous malignancies. Discontinue BRAFTOVI for RAS mutation-positive non- cutaneous malignancies. Monitor patients for new malignancies prior to initiation of treatment, while on treatment, and after discontinuation of treatment. BRAF-mutant type (BRAF-mt) metastatic melanoma (COLUMBUS study): Cutaneous squamous cell carcinoma (cuSCC), including keratoacanthoma (KA), occurred in 2.6% and basal cell carcinoma occurred in 1.6% of patients receiving BRAFTOVI with MEKTOVI.

Monitor patients who already have or who are at significant risk of developing QTc prolongation, including patients with known long QT syndromes, clinically significant bradyarrhythmias, severe or uncontrolled heart failure and those taking other medicinal products associated with QT prolongation. Correct hypokalemia and hypomagnesemia prior to and during BRAFTOVI administration. Withhold, reduce dose, or permanently discontinue for QTc >500 ms. BRAF-mt metastatic melanoma (COLUMBUS study): An increase in QTcF to >500 ms was measured in 0.5% (1/192) of patients who received BRAFTOVI with MEKTOVI. BRAF-mt metastatic NSCLC (PHAROS study): An increase in QTcF to >500 ms was measured in 2.1% (2/95) of patients who received BRAFTOVI with MEKTOVI. Embryo-Fetal Toxicity: Both BRAFTOVI and MEKTOVI can cause fetal harm when administered to a pregnant woman. BRAFTOVI can render hormonal contraceptives ineffective. BRAF-mt metastatic melanoma (COLUMBUS study) and BRAF-mt metastatic NSCLC (PHAROS study): Effective, non-hormonal contraceptives should be used during treatment and for at least 30 days after the final dose for patients taking BRAFTOVI with MEKTOVI. BRAF-mt metastatic CRC (BEACON CRC study): Advise females of reproductive potential to use effective nonhormonal contraception during treatment with BRAFTOVI and for 2 weeks after the final dose. BRAFTOVI as a Single Agent is associated with increased risk of certain adverse reactions compared to when BRAFTOVI is used with MEKTOVI. BRAF-mt metastatic melanoma (COLUMBUS study): Grades 3 or 4 dermatologic reactions occurred in 21% of patients receiving BRAFTOVI as a single agent compared to 2% in patients receiving the combination of BRAFTOVI with MEKTOVI. If MEKTOVI is temporarily interrupted or permanently discontinued, reduce the dose of BRAFTOVI as recommended. Risks Associated with Combination Treatment In BRAF-mt metastatic melanoma (COLUMBUS study), BRAFTOVI is used in combination with MEKTOVI so refer to the prescribing information for MEKTOVI for additional risk information. In BRAF-mt metastatic CRC (BEACON CRC study), BRAFTOVI is used in combination with cetuximab so refer to the prescribing information for cetuximab for additional risk information. In BRAF-mt metastatic NSCLC (PHAROS study), BRAFTOVI is indicated for use as part of a regimen in combination with MEKTOVI, so refer to the prescribing information for MEKTOVI for additional risk information. Additional WARNINGS AND PRECAUTIONS for MEKTOVI When Used With BRAFTOVI Venous Thromboembolism (VTE): VTE occurred in 6% of patients with BRAF-mt metastatic melanoma (COLUMBUS study), including 3.1% of patients who developed pulmonary embolism. VTE occurred in 7% of patients with BRAF-mt metastatic NSCLC (PHAROS study), including 1% of patients who developed pulmonary embolism. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction. Other Ocular Toxicities Serous retinopathy Assess for visual symptoms at each visit. Perform an ophthalmologic examination at regular intervals, for new or worsening visual disturbances, and to follow new or persistent ophthalmologic findings. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction. BRAF-mt metastatic melanoma (COLUMBUS study): serious retinopathy occurred in 20% of patients receiving MEKTOVI with BRAFTOVI; 8% were retinal detachment and 6% were macular edema. Symptomatic serous retinopathy occurred in 8% of patients with no cases of blindness. The median time to onset of the first event of serous retinopathy (all grades) was 1.2 months. BRAF-mt metastatic NSCLC (PHAROS study): serous retinopathy (retinal detachment) occurred in 2% of patients with no cases of blindness. Retinal vein occlusion (RVO) is a known class-related adverse reaction of MEK inhibitors and may occur in patients receiving MEKTOVI with BRAFTOVI. In BRAF-mt metastatic melanoma (COLUMBUS study), 1 patient experienced RVO (0.1%) in the MEKTOVI with BRAFTOVI group (n=690). The safety of MEKTOVI has not been established in patients with a history of RVO or current risk factors for RVO, including uncontrolled glaucoma or a history of hyperviscosity or hypercoagulability syndromes. Perform ophthalmological evaluation for patient-reported acute vision loss or other visual disturbance within 24 hours. Permanently discontinue MEKTOVI in patients with documented RVO. Interstitial Lung Disease (ILD): ILD, including pneumonitis, occurred in 0.3% (2 of 690 patients) with BRAF-mt metastatic melanoma (COLUMBUS study) receiving MEKTOVI with BRAFTOVI. One patient (1%) with BRAF-mt metastatic NSCLC (PHAROS study) receiving MEKTOVI with BRAFTOVI developed pneumonitis. Assess new or progressive unexplained pulmonary symptoms or findings for possible ILD. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction. Rhabdomyolysis: Rhabdomyolysis can occur when MEKTOVI is taken with BRAFTOVI. Monitor creatine phosphokinase (CPK) and creatinine levels prior to initiating MEKTOVI, periodically during treatment, and as clinically indicated. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction. BRAF-mt metastatic melanoma (COLUMBUS study): Elevation of laboratory values of serum CPK occurred in 58% of patients receiving MEKTOVI with BRAFTOVI. Rhabdomyolysis was reported in 0.1% (1 of 690 patients) with BRAF mutation-positive melanoma receiving MEKTOVI with BRAFTOVI. BRAF-mt metastatic NSCLC (PHAROS study): Elevation of laboratory values of serum creatine kinase (CK) occurred in 41% of patients. No patient experienced rhabdomyolysis.
