Practicing physician expertise.
Strategy that reaches
the prescribing physician.
Commack Life Sciences Advisory connects practicing physician expertise, grounded equally in academic medicine and everyday patient care, with the pharmaceutical and biotech teams working to bring new treatments to the patients who need them.
Advisory work grounded in an active clinical practice.
Dr. Paul Feuerstadt, MD, FACG, AGAF, FRCPE, is a board-certified gastroenterologist and Attending Gastroenterologist at PACT Gastroenterology Center in Hamden, CT, where he has practiced since 2011. He also holds academic appointments as Associate Clinical Professor of Medicine at Yale University School of Medicine and Assistant Clinical Professor of Medicine at the Frank H. Netter School of Medicine of Quinnipiac University.
His clinical life is a hybrid practice: he holds academic appointments at Yale and Quinnipiac, but the bulk of his time is spent seeing patients day to day as Attending Gastroenterologist at PACT Gastroenterology Center. That split is deliberate: it means CLSA speaks the language of the academic literature while staying grounded in how a general GI provider actually practices and prescribes.
For over a decade, Dr. Feuerstadt has also worked directly with industry, chairing and moderating advisory boards, leading speaker and sales training, presenting at national and international congresses, and supporting teams from early medical education through commercial launch.
CLSA was founded to make that dual perspective, practicing physician and experienced industry advisor, available as a dedicated consulting partner, with particular depth in C. difficile/microbiome therapeutics, eosinophilic esophagitis, and inflammatory bowel disease.
Where his interest lies
Dr. Feuerstadt's clinical and research interest centers on C. difficile and microbiome-mediated disease, spanning early-stage therapeutic development through the commercial and educational work needed to get a novel treatment into the hands of the physicians who prescribe it, and ultimately to the patients waiting for it.
Two branches, one perspective.
Informed equally by the academic literature and by an active private practice, every service below is ultimately in service of one thing: getting a better treatment to the patient who needs it.
Clinical & Scientific Advisory
- Advisory board design, chairing & moderation: live, virtual, regional, national and global boards
- Medical Science Liaison (MSL) training on disease state, epidemiology, and diagnosis
- Clinical trial data review: Phase 3 data presentations, journal clubs, independent adjudication committee participation
- Disease-state & standard-of-care education for medical affairs and clinical teams
- Course direction for CME summits and clinical education programs
- Medical writing: review articles and clinical trial manuscripts, drawing on a peer-reviewed publication record spanning the New England Journal of Medicine, JAMA Network Open, and the American Journal of Gastroenterology
- Medical education specialist: educational symposium organization and moderation, including program design, faculty moderation, and speaker talent recruitment
Market, Launch & Sales Strategy
- Speakers bureau development & speaker training: case-based presentation training and model presentations for faculty
- Commercial sales team training: national sales meetings, sales kickoff lectures, and launch meeting presentations
- Product theater & congress programming at major GI meetings (ACG, DDW, and regional society meetings)
- Commercial and disease-state education slide deck development: building brand, unbranded, and disease-state education slide content, plus training teams on delivering it effectively
- Public speaking skills training for physician faculty and internal teams
- Media & public-facing communications, including satellite media tours
Depth in GI. Not limited to it.
The deepest track record is in gastroenterology, particularly C. difficile/microbiome therapeutics, eosinophilic esophagitis, and inflammatory bowel disease. But a physician's training doesn't stop at one organ system: it's the ability to master new literature quickly, apply clinical judgment to unfamiliar territory, and translate trial data into practice. That same skill set carries over to any disease state or discipline of medicine a partner needs support in.
C. difficile & Microbiome Therapeutics
Extensive clinical and advisory experience, including advisory boards, speaker and sales training, and payer presentations, as the category has matured from novel to standard-of-care.
Eosinophilic Esophagitis
Active advisory board chairing on EoE study design and care-pathway challenges as diagnostic and treatment approaches continue to evolve.
Inflammatory Bowel Disease
Advisory input on treatment sequencing and positioning, informed by ongoing management of IBD patients in active practice.
Any Discipline of Medicine
Physician training is built to generalize: rapid mastery of new literature, clinical judgment applied to unfamiliar territory, and trial data translated into practice, wherever the question lands, in medicine or surgery alike.
Fifteen years of industry partnerships.
A selection of pharmaceutical and healthcare organizations Dr. Feuerstadt has advised, individually and now through CLSA. Shown here where public disclosure is consistent with each engagement's terms.
Why an oak tree.
The oak wasn't picked at random. It grows slowly, puts down deep roots before it puts up real height, and tends to still be standing a hundred years later, the kind of standard the firm is meant to be held to.
Two branches, one trunk
The trunk splits into two branches of equal length and height, because every pharmaceutical company depends on the medical and commercial sides working together, with neither more important than the other. One branch grows in a direct line; the other winds out further before turning upward, since medical and commercial rarely take identical paths to the same goal.
An acorn, quietly
Look closely and the canopy is built around an acorn. It's subtle by design. An acorn doesn't look like much on its own, but it already contains everything a full-grown oak will become. That's close to how early client work is approached: the groundwork looks small at first, but it's the whole thing in miniature.
The name
Commack is where the founder grew up and went to grade school. The name comes from Winnecomac, a word given to that land by the Secatogue people, usually translated as "pleasant lands," earned in part for its rich soil and oak forests. The link between the name and the tree wasn't planned; it was already there.
It starts and ends with the patient.
Every advisory board, every training session, every trial reviewed traces back to the same purpose: getting a better treatment to the person sitting in the exam room. That's why Dr. Feuerstadt became a physician in the first place, and it's the lens CLSA brings to every partnership: helping pharmaceutical and biotech teams bring novel, meaningful treatments to the patients who are waiting for them.
Let's talk about your next advisory board or launch.
Please reach out for advisory board strategy, speaker or sales team training, clinical trial consulting, or commercial launch support. CLSA takes on a limited number of engagements at a time to keep the clinical input sharp and current.
