NCT05152459

Brief Summary

This phase I/II trial tests the safety, side effects, and best dose of tazemetostat and umbralisib and whether tazemetostat in combination with umbralisib and ublituximab works to shrink tumors in patients with follicular lymphoma that has come back (relapsed) or does not respond to treatment (refractor). Tazemetostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Umbralisib may help block the formation of growths that may become cancer. Ublituximab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Giving tazemetostat in combination with umbralisib and ublituximab may work better in treating follicular lymphoma.

Outcome Measures

Primary Outcomes (2)

  • Dose-limiting toxicity

    Assessed by Common Terminology Criteria for Adverse Events version 5.0. Summarized by type (organ affected or laboratory determination), severity, time of onset, duration, probable association with the study treatment, and reversibility or outcome.

    Up to 28 days (1 cycle)

  • Overall response rate

    Will be estimated by the proportion of response-evaluable patients achieving complete response (CR) or partial response (PR, along with the 95% exact binomial confidence interval.

    Up to 2 years

Secondary Outcomes (5)

  • Complete response rate

    Up to 2 years

  • Time to response

    Up to 2 years

  • Duration of response

    Up to 2 years

  • Overall survival

    From start of protocol treatment to time of death due to any cause, assessed up to 2 years

  • Event-free survival

    From start of protocol treatment to time of disease relapse/progression, start of non-protocol anti-lymphoma therapy due to toxicity of the protocol therapy, or death due to any cause, assessed up to 2 years

Study Arms (1)

Treatment (tazemetostat, umbralisib, ublituximab)

EXPERIMENTAL

Patients receive ublituximab IV on days 1, 8, and 15 of cycle 1, day 1 of cycle 2-6, and day 1 of every 3 cycles thereafter. Patients also receive tazemetostat PO BID umbralisib by PO QD on days 1-28. Treatment repeats every 28 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity.

Eligibility Criteria

Age18 Years+

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Documented informed consent of the participant and/or legally authorized representative
  • Age: \>= 18 years
  • Eastern Cooperative Oncology Group (ECOG) =\< 2
  • Histologically confirmed diagnosis of follicular lymphoma grade 1-3a according to the World Health Organization (WHO) classification, with hematopathology review at the participating institution
  • Relapsed/ refractory disease after at least 2 lines of systemic therapy including an anti-CD20 antibody. Relapse must have been confirmed histologically (with hematopathology review at the participating institution). Exceptions may be granted with study PI approval
  • Active disease meeting requiring treatment per treating physician's decision
  • Radiographically measurable lymphadenopathy or extranodal lymphoid malignancy with one or more sites of disease \>= 1.5 cm in longest dimension
  • Fully recovered from the acute toxic effects (except alopecia) to \<= Grade 1 to prior anti-cancer therapy

  • NOTE: Growth factor is not permitted within 14 days of ANC assessment unless cytopenia is secondary to disease involvement.
