For sponsors, CROs and pharma
RareTrial is a rare disease clinical trial search platform built for patients - not researchers. The people who use this site are already motivated, already diagnosed, and already searching for trials. We are open to partnerships that put your trial in front of them.

Purpose: find a trial
Every person who visits RareTrial is actively looking for a trial. They have a diagnosis. They have a doctor. They are searching by disease name. This is not general health traffic - it is the specific patient population your protocol was written for.
Partnership types
01
Your trial is featured directly on the disease landing page for your condition. Patients searching for trials in that disease category see your study prominently, with a direct link to your trial listing or site contact. Referral tracking available via UTM parameters.
Best for: sponsors and CROs with active recruiting trials in rare diseases covered in our directory.
02
A named sponsorship of a disease profile page - for example, the Spinal Muscular Atrophy page. Your organization is acknowledged as supporting that resource with a tasteful, disclosed placement. The editorial content remains independent and patient-focused.
Best for: companies with an established therapy in a disease who want to support the patient community.
03
Anonymized, aggregated data on what rare disease patients are searching for - by condition, by geography, by trial engagement rate. Delivered quarterly as a structured report. Useful for business development, medical affairs, and trial feasibility teams.
Best for: pharma BD teams and CROs assessing patient availability before a trial launches.
04
We currently have 26 rare disease profiles. If your trial targets a condition not yet in our directory, we will build a dedicated patient-facing profile for that disease - with your trial featured from launch. Editorial standards apply.
Best for: sponsors in ultra-rare or recently classified conditions with no existing patient resource hub.
Our commitment to patients
All commercial relationships are disclosed on the relevant pages. We do not alter eligibility information, trial status, or patient-facing content based on commercial relationships. Patients are told when content is supported by a sponsor. This is non-negotiable.
