The gap we close

Senior medical expertise, precisely when your program needs it

Establishing a credible medical function in neuroscience is demanding: the science moves quickly, advisory boards and publications require experience that early-stage teams rarely hold in-house - and cannot yet justify hiring full-time. ARKH Advisory closes that gap with a senior partner who has led this work inside industry, engaged on a fractional, project, or retained basis and focused specifically on neurology and neuro-diagnostics.

Specialist, not generalist

A dedicated focus on neurodegeneration, Alzheimer's disease, Parkinson's and parkinsonian syndromes, MS, rare neurological disorders, and biomarkers (PET, SPECT imaging, fluid biomarkers, immunofluoresence). Engagements begin productive, with minimal or no ramp-up.

US & EU reach

Direct experience and established thought-leader relationships across both markets - a single partner for transatlantic medical strategy, working US and EU hours.

Senior, on demand

Director-level Medical Affairs without the headcount, overhead, or hiring lead time. Scale engagement up or down by stage, month to month.

Evidence, not adjectives

Published, peer-reviewed, and verifiable

A track record in the peer-reviewed literature on Alzheimer's biomarkers and neuro-imaging - the same scientific rigor brought to every engagement.

For pharma & established teams

Specialist and overflow capacity for in-house Medical Affairs

Publication support

Senior medical writing for manuscripts, reviews, consensus statements, and congress abstracts - to submission-ready, ICMJE-aligned.

KOL mapping

Therapeutic focus

Where ARKH Advisory goes deep

Alzheimer's disease Parkinson's & parkinsonian syndromes Dementia with Lewy bodies Multiple sclerosis Rare neurological disorders Prion diseases Amyloid & tau PET DAT-SPECT imaging Drug development Diagnostic & disease-monitoring biomarkers

If your asset sits in neurology or neuro-diagnostics, this is the consultancy built for it.

A clear scope

Is ARKH Advisory the right fit?

A strong fit

  • You're a biotech, diagnostics / imaging, or pharma medical team working in neuroscience.
  • You need senior Medical Affairs strategy, KOL engagement, advisory boards, or publications, now.
  • You want flexible senior capacity rather than a permanent hire - or specialist, overflow support for an in-house team.
  • You operate in the US, the EU, or both.

Not a fit

  • You need promotional or commercial marketing, or regulatory submissions as a deliverable.
  • Your asset sits outside neurology and neuro-diagnostics.
  • You require a full-time, on-site employee.

About

Alexander Arkhipenko, PhD

A Medical Affairs leader with a PhD in life and health sciences and 9+ years in pharma and biotech, focused on neurodegeneration and diagnostic biomarkers. I have built KOL networks across the US and EU, designed and run advisory boards end-to-end, supported a diagnostic imaging label update, delivered hundreds of scientific presentations, and published with leading experts in journals including Alzheimer's & Dementia.

I founded ARKH Advisory to bring that senior, specialist experience to the companies that benefit most - biotech and diagnostics teams that need the medical thinking before they can build the department, and pharma teams that need neutral specialist or overflow capacity. I work remotely, transatlantically, and on terms that fit your stage.
