• Total Enrollment: 2 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2021-09-01

Brief Summary

This study focuses on finding a safe and tolerable dose for a three-drug regimen that combines venetoclax (Venclexta Ⓡ), CC-486 (also known as oral azacitidine) and obinutuzumab (Gazyva Ⓡ) to treat cancer participants who have minimally pretreated follicular lymphoma and have experienced disease progression despite trying previous cancer therapies. If a safe and tolerable drug dose can be found in the first phase of the study, doctors leading the study will launch a second phase of the study within an expansion cohort. Participants in this expansion cohort will receive the dose established in the first phase of the study to determine the efficacy of the regimen/ established dose. Participants in the expansion cohort will also receive the same study drugs from the first phase of the study, but in a different order/combination (first pairing the two oral drugs, CC-486 and venetoclax, then adding the third drug, obinutuzumab to treatment). The end goal of this research is to establish a new chemotherapy-sparing treatment option for patients with follicular lymphoma that is just as effective (or better) than current standard of care options.

Study Groups

Phase 1(Dose-Finding Arm): Group 1 - Dose Level 1 / Starting Dose

Phase 1/the dose-finding arm of this study will use three dose levels (a starting dose, second dose and highest dose) of the venetoclax, CC-486 and obinutuzumab regimen. If participants in group 1 don't experience severe negative side effects to the starting dose of the regimen, then more participants will be assigned to groups 2 and 3 to take higher doses until the safest/ most tolerable dose is found.

Group 1/ Dose Level 1:

Participants in group 1 will receive a three-drug regimen of venetoclax, CC-486, and obinutuzumab at a starting dose used in previous human studies. Participants in this group will receive:

• Venetoclax:

400 mg on days 1-28

• CC-486:

200 mg on days 1-14

• Obinutuzumab:

1000 mg on days 1, 8 and 15 of cycle 1, and on day 1 of each following cycle.

Treatment using these three study drugs (venetoclax, CC-486, and obinutuzumab) will be given in 12 consecutive cycles that run for 28 days during each cycle (336 days).

Group Type: EXPERIMENTAL

Venetoclax

Intervention Type: DRUG

A drug used with other drugs to treat acute myeloid leukemia that is newly diagnosed. It is used in adults who are 75 years and older or in adults who cannot be treated with other anticancer drugs. Venetoclax is also used to treat chronic lymphocytic leukemia and small lymphocytic lymphoma in adults. It is also being studied in the treatment of other types of cancer.

Obinutuzumab

Intervention Type: DRUG

Obinutuzumab is a prescription medicine that can be used in combination with other cancer medicines to treat follicular lymphoma (a type of non-Hodgkin lymphoma), or to help delay the progression of this disease.

CC-486

Intervention Type: DRUG

An oral form of azacitidine (a standard chemotherapy drug).

Phase 2 (Efficacy Arm/ Expansion Cohort)

Participants in this arm will help test the efficacy of the three-drug regimen and dose established in the phase 1 of the study. Participants will take two drugs (venetoclax and CC-48) used in the same three-drug regimen during the first phase of this study. These two drugs will be paired together by themselves and given to participants in the expansion cohort before obinutuzumab (a third drug) is added during cycle 4 of treatment.
