BOULDER, CA, USA I June 27, 2018 I Array BioPharma Inc. (Nasdaq: ARRY) today announced that the U.S. Food and Drug Administration (FDA) has approved BRAFTOVI™ capsules in combination with MEKTOVI® tablets for the treatment of patients with unresectable or metastatic melanoma with a BRAFV600E or BRAFV600K mutation, as detected by an FDA-approved test. BRAFTOVI is not indicated for the treatment of patients with wild-type BRAF melanoma.

“We are thrilled with the approval of BRAFTOVI + MEKTOVI, which help fill a critical unmet need for patients with advanced BRAF-mutant melanoma, a serious and deadly type of skin cancer,” said Ron Squarer, Chief Executive Officer, Array BioPharma. “As presented at ASCO, BRAFTOVI + MEKTOVI is the first targeted treatment to demonstrate over 30 months median overall survival in a Phase 3 trial. These products represent a new standard of care for BRAF-mutant melanoma patients and we sincerely thank the patients and dedicated researchers who participated in our clinical program.”

BRAFTOVI + MEKTOVI are now available to order through select specialty pharmacies in the U.S. market.

“Despite recent advances, there remains a significant unmet need for treatments that are both effective and well-tolerated for patients with BRAF-mutant melanoma,” said Keith T. Flaherty, M.D., Director of the Termeer Center for Targeted Therapy, Massachusetts General Hospital Cancer Center and Professor of Medicine, Harvard Medical School. “Now, physicians and patients have the option to consider treatment with BRAFTOVI + MEKTOVI, which has been shown to delay disease progression, improve overall survival and is generally well-tolerated.”

“Nearly half of patients diagnosed with metastatic melanoma test positive for the BRAF mutation,” said Valerie Guild, Co-Founder and President of the AIM at Melanoma Foundation. “Today’s approval is welcome news for the melanoma community as it arms BRAF-mutant late-stage melanoma patients with an important new targeted treatment in their fight against this devastating disease.”

The approval of BRAFTOVI + MEKTOVI is based on results from the Phase 3 COLUMBUS trial, which demonstrated the combination doubled median progression-free survival (mPFS) compared to vemurafenib, alone (14.9 months versus 7.3 months, respectively [HR (0.54), (95% CI 0.41-0.71), p<0.0001]). Only 5% of patients who received BRAFTOVI + MEKTOVI discontinued treatment due to adverse reactions.

The most common adverse reactions (≥25%) in patients receiving BRAFTOVI + MEKTOVI were fatigue, nausea, diarrhea, vomiting, abdominal pain, and arthralgia.

As announced in February 2018, BRAFTOVI + MEKTOVI reduced the risk of death compared to treatment with vemurafenib 960 mg daily [hazard ratio (HR) of 0.61, [95% CI 0.47, 0.79, p <0.001] in the planned analysis of overall survival (OS) from the COLUMBUS trial. Median OS was 33.6 months for patients treated with the combination, compared to 16.9 months for patients treated with vemurafenib as a monotherapy. These positive results add to the growing body of clinical evidence supporting the BRAF/MEK inhibitor combination therapy and Array and its partners are working to formally submit these results with global regulatory authorities.

Array BioPharma is committed to providing access and reimbursement support to all patients. Array offers a $0 copay for eligible, commercially-insured patients. For more information about treatment of BRAFTOVI in combination with MEKTOVI, visit www.braftovimektovi.com.

About BRAF-mutant Metastatic Melanoma
Melanoma develops when unrepaired DNA damage to skin cells triggers mutations that may lead them to multiply and form malignant tumors. Metastatic melanoma is the most serious and life-threatening type of skin cancer and is associated with low survival rates. [1, 2] There are a variety of gene mutations that can lead to metastatic melanoma. The most common genetic mutation in metastatic melanoma is BRAF. There are about 200,000 new cases of melanoma diagnosed worldwide each year, approximately half of which have BRAF mutations, a key target in the treatment of metastatic melanoma. [1, 3, 4, 5]

About BRAFTOVI + MEKTOVI
BRAFTOVI is an oral small molecule BRAF kinase inhibitor and MEKTOVI is an oral small molecule MEK inhibitor which target key enzymes in the MAPK signaling pathway (RAS-RAF-MEK-ERK). Inappropriate activation of proteins in this pathway has been shown to occur in many cancers including melanoma, colorectal cancer, non-small cell lung cancer, thyroid and others. In the U.S., BRAFTOVI + MEKTOVI are approved for the treatment of unresectable or metastatic melanoma with a BRAFV600E or BRAFV600K mutation, as detected by an FDA-approved test. BRAFTOVI is not indicated for treatment of patients with wild-type BRAF melanoma.

Array has exclusive rights to BRAFTOVI and MEKTOVI in the U.S. and Canada. Array has granted Ono Pharmaceutical exclusive rights to commercialize both products in Japan and South Korea and Pierre Fabre exclusive rights to commercialize both products in all other countries, including Europe, Asia and Latin America.

BRAFTOVI + MEKTOVI are not approved outside of the U.S. The European Medicines Agency (EMA), as well as the Swiss Medicines Agency (Swissmedic) and the Australian Therapeutic Goods Administration (TGA), are currently reviewing the Marketing Authorization Applications submitted by Pierre Fabre, and Japan’s Pharmaceuticals and Medical Devices Agency has accepted the Manufacturing and Marketing Approval applications submitted by Ono Pharmaceutical Co, Ltd.

About COLUMBUS
The COLUMBUS trial (NCT01909453) is a two-part, international, randomized, open label Phase 3 trial evaluating the efficacy and safety of BRAFTOVI (encorafenib) in combination with MEKTOVI (binimetinib) compared to vemurafenib and encorafenib monotherapy in 921 patients with locally advanced, unresectable or metastatic melanoma with BRAFV600 mutation. All secondary efficacy analyses, including overall survival, are descriptive in nature. Over 200 sites across North America, Europe, South America, Africa, Asia and Australia participated in the trial.

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 BRAFV600E or BRAFV600K mutation, as detected by an FDA-approved test.

Limitations of Use: BRAFTOVI is not indicated for the treatment of patients with wild-type BRAF melanoma.
