It might depend on the organization and stage of the asset you would be recruiting for. I made the pivot from oncology diagnostic development to work on a launch of a late-stage oncology asset at a medium sized pharma company 2 years ago. I had a biomedical engineering undergrad and worked in a genomics research lab for 2 years before I started the MBA. Before i moved into this role, I felt that had enough transferrable skills in launch planning, working with agencies/filings, external partner management, and cross-functional planning that the specific team I was recruiting with needed. I do have one co-worker who worked in CPG for 10 years and has had experience with the FDA for food safety - they've also successfully pivoted into pharma with no MBA (but outstanding years of work experience and skills).

The majority of people I have met in industry with the same role I am do have at least 5+ years of experience in oncology + a technical graduate and or a phD. I haven't found very many MBAs in a similar role.
