Case Study:
Bristol Myers Squibb (BMS) received approval for OPDUALAG from FDA on 18 March 2022, for the treatment of adult and pediatric patients (12 years and older and weighing at least 40 kg) with unresectable or metastatic melanoma. This review was conducted under Project Orbis and used the Real-Time Oncology Review (RTOR) pilot program. This application was granted priority review, fast track designation, and orphan drug designation.
Please review the reference website provided below and answer the following questions:
What is OPDUALAG treatment used for and how it is different from the other established treatments options? You can discuss the importance of dual immunotherapy (OPDUALAG) over the nivolumab monotherapy.
What are some regulatory considerations that BMS would have taken to gain approval for OPDUALAG? You can discuss the set-up of the RELATIVITY-047 trial here. Explain how progression-free survival (PFS) was used as a major efficacy outcome measure.
Why would BMS receive priority review, fast track designation, and orphan drug designation from the FDA?
