Study Summary

This trial is testing ATRC-101, an antibody derived from a naturally occurring human antibody, for safety, tolerability, PK, and biological activity when administered every 2 weeks or every 3 weeks as a monotherapy or in combination with other anticancer agents.

Who is the study for?
Adults with certain advanced cancers (like breast, lung, colorectal, ovarian cancer or melanoma) that can't be removed by surgery or have spread and don't respond to standard treatments. They must have measurable disease and adequate organ function. Women who can bear children and men with partners of this potential must use effective birth control.Check my eligibility
What is being tested?
ATRC-101 is being tested alone or with other cancer drugs (Pembrolizumab/PLD). This trial checks its safety, how the body handles it, and if it works against cancer when given every 2 or 3 weeks. It's an early-phase study where everyone gets the experimental treatment.See study design
What are the potential side effects?
Possible side effects include reactions related to the immune system affecting organs, infusion-related reactions which could happen during drug administration, fatigue, blood disorders like changes in 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.

What are some of the conditions that ATRC-101 is meant to alleviate?

"ATRC-101 is an investigational medication that has the potential to treat patients with unresectable melanoma, microsatellite instability high, and neuroblastoma (nb)."

Answered by AI

Is there a potential for abuse with ATRC-101?

"ATRC-101 has only been trialled in Phase 1 clinical trials, so there is limited evidence to support its safety."

Answered by AI

Is this the first time that ATRC-101 has been tested in a clinical setting?

"ATRC-101 was first trialled in 1997 at Spectrum Health Hospital. So far, there have been a total of 916 completed clinical trials. Right now, there are 1358 active studies, a number of which are taking place in Oklahoma City, Oklahoma."

Answered by AI

Is this clinical trial running in more than one place?

"The research teams conducting this study are based in the Stephenson Cancer Center, University of Oklahoma Health Sciences Center in Oklahoma City, Oklahoma, Massachusetts General Hospital in Boston, Massachusetts, and Mayo Clinic in Rochester, Minnesota. There are also 13 other active locations."

Answered by AI

Do we have room for more study participants?

"That is correct, the trial is still recruiting patients. The clinicaltrials.gov website indicates that the trial was first posted on February 11th, 2020 and was last updated September 28th, 2020. There are 240 patients enrolled at 13 locations."

Answered by AI

Is this research project newly conceived?

"ATRC-101 has been subject to 1358 clinical trials since 1997, when the first Phase 3 drug approval trial was completed. These trials have taken place across 72 countries and 3391 cities."
