Palmoplantar Pustulosis

What are the study procedures?

We are looking for men and women who are 18 years or older; but younger than 75 years, and who
are willing to participate in a clinical trial with the investigational medication RIST4721. You will receive
physical examinations, your palmoplantar pustulosis will be evaluated and your blood and urine will be
collected for laboratory tests. Photos of your hands and feet will also be taken.

The aim of the study is to examine the safety and effectiveness of the study medication RIST4721.

The study medication is compared to placebo. The placebo will look like RIST4721, but it will not
contain active medication. You will be randomly assigned to study medication or placebo. You will
have a 1 out of 3 chance of receiving placebo.

How long does the study run?

The study will last approximately 4 months during which you will have to visit the study site 7 times.
Reasonable travel expenses while participating in the study will be reimbursed.

Which subject characteristics are we looking for?

Men and women who are 18 years or older, but younger than 75 years, who have been diagnosed
with palmoplantar pustulosis for at least 6 months.

Our Patient Reviews

Dr. Weisman was very professional, friendly, and engaged in conversation with terminology I would understand. Her beside manner was, quite frankly, surprising! It was one of the most comfortable visits I've ever experienced with a doctor.
Jeffery D.
Dr. Weisman is a great doctor! She was very informative and personally! Her staff were very welcoming as well I'm glad I found her because she is the only doctor who truly explained what was going with me.
Waquele H.
I truly cannot express how thankful I am for this practice. I have been treated with kindness and immense care by every staff member I have encountered here. The nurses and assistants are beyond attentive and genuinely care for the patient. I have just received a treatment plan from Dr. Laura Biehl, and even if this particular treatment plan doesn't provide me relief, I am confident that Dr. Biehl will work to figure out a solution. She is extremely knowledgeable, listens to patient concerns, and takes time to answer patient questions. Dr. Biehl, and this practice are true gems. If you have any dermatological issues this practice is absolutely the best of the best.
