Study summary

This study in patients with relapsed/refractory follicular lymphoma who have undergone at least 3 lines of therapy. Patients will receive abexinostat 80 mg (4 × 20 mg tablets) twice a day (BID) in a "one week on, one week off" schedule.

Read the detailed description

Patients will be evaluated for objective response, Duration of Response (DOR), Progression Free Survival (PFS), Clinical Benefit Rate (CBR), Overall survival (OS), safety and tolerability, pharmacokinetic (PK), pharmacodynamic (PD), and changes in health related quality of life. Patients may receive treatment until disease progression, death, unacceptable toxicity, or withdrawal of consent. An independent data safety monitoring committee (iDMC) will evaluate the data pertaining to the futility and decide whether the study should stop or continue to the second stage. If the study continues to the second stage, a total of 139 patients will be studied.

  • Has histologically confirmed Grade 1, 2, or 3a follicular lymphoma.
  • Has follicular lymphoma that has relapsed after (progressed after 6 months from the start of therapy) or is refractory to the last line of therapy (no response or progression within 6 months from the start of therapy) and needs treatment (must have at least 1 lymph node or extranodal lymphoid malignancy radiologically measuring ≥ 3 cm in its longest diameter).
  • Female patients must fulfil the following criteria:

    a. Be of non-childbearing potential, defined as follows: i. Postmenopausal (ie, ≥ 1 year without any menses) prior to Screening, or ii. Documented surgically sterile (≥ 1 month prior to Screening)

  • Male patients must agree not to donate sperm starting from the time of Screening, throughout the study, and until after 90 days following the last dose.
  • Use highly effective forms of birth control (women of childbearing potential only), which include the following:

    i. Consistent and correct use of established oral contraception ii. Established intrauterine device or intrauterine system iii. Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository.

  • Female patients must agree not to breastfeed starting from the time of Screening, throughout the study, and until after 90 days following the last dose.
  • Male patients and their female spouse/partners who are of childbearing potential must use highly effective contraception methods consisting of 2 forms of birth control (at least 1 of which must be a barrier method) from the time of Screening, throughout the study, and until after 90 days following the last dose.
  • Male patients must agree not to donate sperm starting from the time of Screening, throughout the study, and until after 90 days following the last dose.

Exclusion criteria

Exclusion Criteria:

  • Has had prior treatment with abexinostat.
  • Has had allogeneic stem cell transplant within the last 6 months, or autologous stem cell transplant within the last 3 months before enrollment
  • Has any types of cardiac impairment at the time of enrollment
  • Has received any investigational medication within 30 days or 5 half-lives prior to Day 1, whichever is longer

What researchers measure

Primary outcomes

  1. Clinical effect of abexinostat

    Complete response (CR) or partial response (PR) according to the Lugano 2014 criteria as determined by an Independent Review Committee (IRC).

    Time frame: Time frame up to 100 months

Secondary outcomes

  1. Duration of response

    Duration of response defined as the time from first documented evidence of CR or PR until disease progression or death from any cause among patients who achieve an objective response, according to the Lugano 2014 criteria as determined by an IRC.

    Time frame: At the end of cycle 2 (each cycle is 28 days) and through study completion, assessed up to 100 months.

  2. Progression free survival

    Defined as the time from the start of treatment until disease progression or death assessed using the Lugano 2014 criteria as determined by an IRC.

    Time frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 100 months

  3. Clinical Benefit

    Defined as the best from CR, PR, or stable disease (SD) according to the Lugano 2014 criteria as determined by an IRC.

    Time frame: At the end of cycle 2 (each cycle is 28 days) and through study completion, assessed up to 100 months.

  4. Overall survival

    Defined as the time from the start of treatment until death from any cause or last contact.

    Time frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 100 months

  5. Duration of response

    Defined as the time from first documented evidence of CR or PR from any cause among patients who achieve an objective response, according to the RECIL 2017 as determined by an IRC. Duration of response will be evaluated once more using the RECIL 2017 with the inclusion of Minor Response (MR) lasting ≥ 6 months.

    Time frame: At the end of cycle 2 (each cycle is 28 days) or from date of randomization until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 100 months

  6. Incidence of adverse events

    Safety as measured by the incidence of adverse events

    Time frame: At the end of cycle 2 (each cycle is 28 days) or from date of randomization until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 100 months

  7. Incidence of serious adverse events

    Safety as measured by the serious of adverse events (SAE)

    Time frame: At the end of cycle 2 (each cycle is 28 days) or from date of randomization until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 100 months

  8. Incidence of non-serious adverse events

    Safety as measured by the non-serious of adverse events

    Time frame: At the end of cycle 2 (each cycle is 28 days) or from date of randomization until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 100 months

  9. Change in the interval corrected for heart rate (QTc) interval

    Change from baseline in the QTc interval.

    Time frame: At the end of cycle 2 (each cycle is 28 days) or from date of randomization until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 100 months
