Fractional Clinical Leadership

Senior medical leadership at the moments that matter.

Clinical-stage biotechs face pivotal decisions that require experienced CMO-level judgment — without the full-time executive commitment. Dr. Ashok brings 135 trials and three BLAs to your most critical milestones.

Scope your engagement on one call
The clinical leadership gap

Scientist CEOs need clinical guidance at exactly the moment capital efficiency matters most.

Most scientist-founded biotechs have brilliant science and no internal medical leadership — at the stage when its absence is most costly.

Protocol risk

Protocol amendments cost $100K–$500K each and add 4–6 months to your timeline. The right clinical leadership prevents most of these before they happen.

Regulatory exposure

FDA meetings are make-or-break moments — without experienced medical leadership, you may not ask the right questions or bring the right data.

Investor credibility

Investors are asking for clinical strategy you haven't validated — and you need a credible medical voice to back your roadmap.

Common questions

Frequently asked questions

How quickly can you start?

Most engagements begin within 2 weeks of SOW signature.

Do you work with companies outside the US?

Yes. Dr. Ashok has filed INDs across FDA, EMA, PMDA, and DCGI, and works with companies globally.

Is this separate from AyurDatta's safety governance services?

The clinical advisory can be engaged completely independently. Many clients use only the fractional CMO engagement. Others engage both — clinical medical leadership and safety governance oversight — and benefit from the integration between them.

What if my need is project-based rather than ongoing?

Project-based engagements are the most common starting point. Most convert to an ongoing retainer after the first defined project.

Need technology and medical leadership together?

Combine Fractional CMO and Fractional CTO support for unified clinical and platform execution.
