we could create novel therapeutics that benefit more patients, sooner, by building internal drug development expertise and capability that harnesses the power of Flagship’s unique ecosystem of bioplatform companies?

Pioneering Medicines is Flagship’s in house drug discovery and development unit. Our team of drug development experts creates new therapeutics built from Flagship’s innovative bioplatforms and novel modalities.

More than 40 companies across the Flagship ecosystem are pioneering innovative platform technologies to address major challenges in human health. Pioneering Medicines explores and identifies new product concepts and then works jointly with Flagship’s companies to form integrated teams that advance medicines through robust discovery and early clinical development.

Pioneering Medicines also partners with external collaborators across biopharma throughout our R&D process. We apply our unique approach to the R&D priorities of our partners through highly co-creative relationships that draw on the expertise of our respective teams.

Pioneering Medicines leads Flagship’s Innovation Supply Chain Partnerships with Novo Nordisk and Pfizer to speed innovation in drug development and bring novel therapies to patients.


Our Pipeline

Pioneering Medicines’ portfolio includes programs in multiple therapeutic areas including obesity, MASH, Lupus, and other disease areas representing significant unmet medical need for millions of people around the world.

Our portfolio includes both partnered and internal programs. Our goal for our internal programs is to develop assets through human proof-of-concept and seek the most appropriate partner to acquire or license each asset for late-stage development and commercialization. We are also open to transacting assets earlier and welcome partnering discussions at any point in our R&D process.

as of March 1, 2025

Our R&D Process

Pioneering Medicines leverages Flagship's unique innovation process and the diverse expertise of its team to take multiple approaches to explorations and to identifying new product concepts. Some explorations target a particular disease area, some a specific target or pathway, and others a particular bioplatform technology.

We conduct these explorations ourselves or with an external partner based on their priority areas. Once we have a medicine concept, we conduct early research to determine the scientific feasibility and market fit of the potential asset. We develop robust discovery and pre-clinical plans and prioritize which assets to move forward as a single asset company.

In close partnership with a particular Flagship bioplatform company, Pioneering Medicines then focuses on driving the asset to a candidate for preclinical development. We conduct pre-IND activities, and if the data are supportive, develop clinical plans and move toward filing an IND. We then initiate Phase I clinical trials and work toward demonstrating human proof-of-concept. At this point, if an internal program, we also begin discussions to identify a company to acquire the asset for late development and commercialization.

Our Current Partnerships

We are a 100+ person team of drug discovery and development experts who have collectively been involved in over 600 R&D programs and led over 80 approvals across multiple therapeutic areas and across multiple modalities. Our team leverages experience from all the major pharma companies and leading biotechs to achieve one common goal: to make new medicines for patients sooner.
