Study Endpoints

Primary Endpoints

To describe dose limiting toxicities (DLT) of PRT543
Baseline through Day 28.

Dose limiting toxicities (DLTs) will be evaluated during the first cycle

To determine the maximally tolerated dose (MTD)
Baseline through approximately 2 years.

The maximum tolerated dose (MTD) will be established for further investigation in participants with advanced malignancies who have failed prior treatments.

To determine the recommended phase 2 dose (RP2D) and schedule of PRT543
Baseline through approximately 2 years.

The recommended phase 2 dose (RP2D) and optimal dosing schedule of PRT543 will be established for further investigation in participants with advanced malignancies who have failed prior treatments.

Secondary Endpoints

To describe the adverse event profile and tolerability of PRT543
Baseline through approximately 2 years
To determine the maximum observed plasma concentration (Cmax) of PRT543
Cycle 1 (each cycle is 28 days) on Days 1, 15, and/or 25: predose and 0.5, 1, 2, 4, 8, 24 hours postdose; predose on Cycle 1, Days 3, 4, 8, 11, and/or 22. Subsequently for Cycle 2 and beyond (until end of study treatment) on Day 1.
To determine the time to reach maximum observed plasma concentration (Tmax) of PRT543
Cycle 1 (each cycle is 28 days) on Days 1, 15, and/or 25: predose and 0.5, 1, 2, 4, 8, 24 hours postdose; predose on Cycle 1, Days 3, 4, 8, 11, and/or 22. Subsequently for Cycle 2 and beyond (until end of study treatment) on Day 1.

Frequently asked questions about PRT543

What is PRT543 used for?

PRT543 is an investigational small molecule being studied for the treatment of relapsed or refractory advanced solid tumors. It is also being evaluated in hematologic malignancies including diffuse large B-cell lymphoma, myelodysplasia, myelofibrosis, adenoid cystic carcinoma, mantle cell lymphoma, acute myeloid leukemia, and chronic myelomonocytic leukemia.

Who makes PRT543?

PRT543 is being developed by Prelude Therapeutics Incorporated, a biopharmaceutical company traded on the NASDAQ under the ticker symbol PRLD. The company is conducting clinical research to evaluate the safety and efficacy of this investigational drug in patients with advanced cancers.

What phase is PRT543 in?

PRT543 is in Phase 1 clinical development. It is an investigational drug and has not been approved by the FDA. The Phase 1 study has been completed, and the drug remains under clinical investigation for the treatment of advanced solid tumors and certain hematologic malignancies.

What clinical trials is PRT543 in?

PRT543 has been studied in one clinical trial, identified as NCT03886831. This Phase 1 study, titled 'A Study of PRT543 in Participants With Advanced Solid Tumors and Hematologic Malignancies,' was conducted in the United States and has been completed. The trial enrolled 232 participants aged 18 years and older.

Is PRT543 the same as any other drug?

PRT543 is a distinct investigational small molecule developed by Prelude Therapeutics. No alternative names for PRT543 have been reported in the clinical trial data. It is being studied as a monotherapy in an uncontrolled, non-randomized Phase 1 trial for advanced cancers.
