Submit A PAD Trial
Partner with PAD Trials to connect the right patients with high‑quality, high-quality PAD research.
PAD Trials is an initiative of the Global PAD Association, created to connect patients, families, and clinicians with up‑to‑date information on peripheral arterial disease (PAD) and chronic limb threatening ischemia (CLTI) clinical trials around the world. PAD Trials works with investigators, sponsors, and clinical teams who are committed to rigorous science, transparent communication, and limb preservation. Use this page to learn how we collaborate, what we look for in trials, and how to submit your study for review by our Medical Advisory Board.

Level 3 - Follow the Patient Journey — Before, During, and Beyond the Trial
This is where PAD Trials becomes part of the patient journey—not just the trial.
We support them with:
-
from initial interest
-
through qualification
-
through participation (if enrolled)
-
and even beyond the trial
Your team also gains access to HIPAA-compliant, real-world journey insights:
-
patient interest in your trial (even if they don’t qualify)
-
progression through the decision and enrollment process
-
real-world experience during participation
-
patient-reported perspectives and future testimonials (when appropriate)
👉 This gives you something most trials never see:
What actually happens to patients in the real world—not just inside the protocol
We stay with patients throughout their journey:
-
education and decision support
-
appointment preparation
-
information about resources to assist with co-pay relief and transportation
-
where appropriate and separately from the trial itself, patients may also be connected to GPAD's free support programs, including walking, diet coaching, and smoking cessation resources — offered independently of their trial participation.
Level 2 - Engage Patients Actively Seeking Options
We don’t just list your trial—we bring it into real patient conversations.
Patients contacting our hotline and community are actively looking for answers. When appropriate, your study becomes part of those conversations.
We also capture insight into:
-
who is asking about your trial
-
who may qualify
-
where barriers exist
👉 You’re no longer waiting for patients—you’re part of the flow.
Level 1 - Be Discoverable to the Right Patients
Your study is reviewed and added to the PAD Trials platform with clear, patient-friendly information.
Patients can explore your trial, ask questions, and receive information on a participating site near them.
👉 This is where visibility starts.
This level of engagement translates into meaningful visibility and real patient connection for your trial.
Here’s how partners work with PAD Trials depending on their goals.

Trial Review Standards
What We Look For in Submitted Trials
We focus on studies that are transparent, clearly described, and relevant to patients navigating PAD and CLTI.
Trials featured on PAD Trials are reviewed by our Medical Advisory Board to ensure they meet a high standard of clarity, safety, and relevance to real-world patient care. Aside from a trial being registered on ClinicalTrials.gov, actively recruiting, and peer-reviewed or institutional affiliation...
Which Map Are You Submitting For?
PADtrials.org features two separate trial maps, each with its own listing criteria:
CLTI Trial Map — For device, procedure, and medication trials focused on Critical Limb-Threatening Ischemia and limb salvage. These trials are reviewed against our core listing criteria by the Medical Advisory Board.
PAD Life Trial Map — For broader PAD research including devices, lifestyle interventions, supervised exercise, dietary modification, and smoking cessation studies. These trials are reviewed against a separate set of criteria developed for general interventional, non-interventional, and behavioral health studies.
Please indicate which map you are submitting for in the Program Selection field below. If you are unsure, our team will help determine the right fit.
We look for:
-
Clear scientific rationale and well-defined endpoints
-
Appropriate safety monitoring and ethical oversight
-
Relevance to PAD populations, including limb-salvage considerations
-
Transparency around risks, benefits, and eligibility criteria
We prioritize studies that patients can realistically understand, evaluate, and discuss with their care teams.
Inclusion on PAD Trials is not an endorsement or guarantee of outcomes. It reflects that a study meets baseline criteria for transparency, design quality, and relevance to PAD care.
