To determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) of oral fimepinostat (CUDC-907) in combination with venetoclax and rituximab
At the end of cycle 1 or 2 (each cycle is 21 days)

To be evaluated in patients with relapsed and/or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) or high-grade B-cell lymphoma (HGBL). Within any given study arm, the highest dose level studied at which fewer than 2 out of 6 subjects (\< 33%) experience a dose limiting toxicity (DLT).

To assess the safety and tolerability of fimepinostat in combination with anti-cancer regimens by evaluating the number of participants with adverse events assessed using the NCI Common Terminology Criteria for Adverse Events (CTCAE, v4.0).
18 months

Number of participants with adverse events assessed using the NCI Common Terminology Criteria for Adverse Events (CTCAE, v4.0).

To evaluate the efficacy of fimepinostat in combination with anti-cancer regimens by evaluating ORR
24 months

ORR assessments as measured using Lugano criteria.

To evaluate the efficacy of fimepinostat in combination with anti-cancer regimens by evaluating DOR
24 months

DOR assessments as measured using Lugano criteria.

Penetration of fimepinostat across the blood brain barrier (BBB)
During surgery or biopsy

Will be analyzed using descriptive statistics from results of fimepinostat concentrations measured within the tumor tissue collected at the time of a standard of care surgery or biopsy. Within each strata, Simon's two-stage design will be used.

Fimepinostat - Combination w/ venetoclax and rituximabEXPERIMENTALFimepinostat and venetoclax dosed at dose levels determined for that combination. Rituximab dosed at 375 mg/m2 IV on Day 1 of each 21 day cycle
Treatment (fimepinostat, tumor resection)EXPERIMENTALPatients receive fimepinostat by mouth once daily, on Days -2 to 0. Within 2 hours of receiving fimepinostat on Day 0, patients undergo tumor resection or biopsy as part of their standard of care. MAINTENANCE PHASE: Patients receive fimepinostat by mouth, once daily for days 1-5 each week. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity for up to 12 months from the time treatment begins. Should patients continue to derive clinical benefit, and not experience excess toxicity or progression, patients can continue to receive drug for up to 24 months or longer pending discussion with study chairs and study sponsor.

Frequently asked questions about CUDC-907

What is CUDC-907 used for?

CUDC-907 is an investigational small molecule being studied for oncology indications including relapsed and/or refractory diffuse large B-cell lymphoma with MYC alterations, triple-negative breast cancer, and other advanced solid tumors and lymphomas. It is being developed by Curis, Inc. and is not yet approved.

Who makes CUDC-907?

CUDC-907 is being developed by Curis, Inc., a biopharmaceutical company traded under the ticker CRIS. The drug is an investigational small molecule in clinical development for oncology indications, including lymphoma and triple-negative breast cancer.

What phase is CUDC-907 in?

CUDC-907 has completed Phase 1 and Phase 2 clinical trials. It is an investigational drug, meaning it is not FDA approved and remains in clinical development. Completed trials include a Phase 1 study in advanced solid tumors and a Phase 2 study in relapsed or refractory diffuse large B-cell lymphoma.

What clinical trials is CUDC-907 in?
