Study Summary

This trial is testing different combinations of drugs to find the best dose of each to treat cancer, while also looking at how well the drugs work and what side effects they have.

Who is the study for?
Adults with relapsed or refractory Peripheral T-cell lymphoma (PTCL) or Cutaneous T-cell Lymphoma (CTCL), who can provide consent and a recent tumor sample. They must have adequate organ function, no severe unresolved side effects from past cancer treatments, not be on immunosuppressants, and agree to use contraception. Excluded are those with active infections, certain other cancers, CNS metastases, autoimmune diseases requiring treatment in the last 2 years, known allergies to trial drugs or their components.Check my eligibility
What is being tested?
The study is testing combinations of Pembrolizumab with Decitabine and Pralatrexate in patients with PTCL and CTCL. It aims to find the highest dose patients can tolerate without serious side effects (MTD), recommend doses for future phases (RP2D), identify dose-limiting toxicities (DLTs), and assess how well these drug combos work at MTD.See study design
What are the potential side effects?
Potential side effects include reactions related to immune system activation such as inflammation of organs; infusion-related reactions; fatigue; digestive issues like nausea or diarrhea; blood disorders that could affect cell counts leading to increased infection risk.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

How many participants are participating in this investigation?

"To initiate the clinical trial, 37 individuals fitting a predetermined set of criteria must enroll. Both Allegheny Health Network in Pittsburgh and University of Virginia located in Charlottesville are participating sites."

Answered by AI

Are there any existing investigations that involve Pembrolizumab?

"1062 clinical trials are currently being conducted on Pembrolizumab, 137 of which are in the third stage. Houston is a major hub for this research with 37248 total locations researching this drug."

Answered by AI

Are participants of this experiment restricted to any age group?

"The parameters for enrollment in this trial stipulate that participants must be at least 18 years old and not exceed the age of 90."

Answered by AI

What health conditions is Pembrolizumab primarily administered for?

"Pembrolizumab is the primary treatment for unresectable melanoma, but it can also be utilized to address microsatellite instability high, potential relapse risk, and other ailments."

Answered by AI

Am I eligible to join the experiment?

"Participation in this medical trial is open to those between the ages of 18 and 90 who have been diagnosed with ptcl. As of now, 37 individuals are needed for inclusion."

Answered by AI

What is the goal of this medical experiment?

"Merck Sharp and Dohme LLC, the sponsor of this clinical trial, have stated that Maximum Tolerated Dosage (MTD) will be used to measure the primary outcome over a period of 1-2 years. The secondary outcomes being studied are pharmacodynamic markers, anti-tumor activity, and pharmacokinetic profiles for pembrolizumab in conjunction with pralatrexate (Arm A), decitabine (Arm C), or as part of a combination therapy within cycle one only."

Answered by AI

Are there currently any openings for participants in this scientific experiment?

"Affirmative. As per clinicaltrials.gov, this research endeavor is currently recruiting patients - it was originally announced on February 2nd 2022 and the most recent update occured on July 18th 2022."

Answered by AI

Is Pembrolizumab well-tolerated and without risk for patients?

"Preliminary evidence indicates Pembrolizumab is safe, which has been reflected with a rating of 1 on our safety scale. This score was assigned due to the drug's Phase 1 status and limited supportive data concerning its efficacy."
