Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Safety and tolerability of parsaclisib in combination with bendamustine and obinutuzumab in relapsed or refractory FL, assessed by number of subjects with adverse events (AEs) [ Time Frame: Screening through 30-35 days after end of treatment, up to approximately 34 months per subject ]

Secondary Outcome Measures :
  1. Objective response rate based on Lugano classification criteria [ Time Frame: Protocol-defined timepoints throughout the treatment period, up to approximately 34 months per subject ]
    Defined as percentage of subjects with a complete response (CR) and partial response (PR), as determined by investigator assessment of response

  2. Complete response rate based on Lugano classification criteria [ Time Frame: Protocol-defined timepoints throughout the treatment period, up to approximately 34 months per subject ]
    Defined as percentage of subjects who achieve a best overall response of CR

  3. Duration of response [ Time Frame: Protocol-defined timepoints throughout the treatment period, up to approximately 34 months per subject ]
    Defined as time from first documented evidence of CR or PR until earliest date of disease progression or death due to any cause.

  4. Progression-free survival [ Time Frame: Protocol-defined timepoints throughout the treatment period, up to approximately 34 months per subject ]
    Defined as time from the date of the first dose of study drug until the earliest date of disease progression (determined by radiographic disease assessment/Lugano classification criteria) or death due to any cause.

  5. Overall survival [ Time Frame: From the date of the first dose of study drug until death due to any cause, assessed up to approximately 34 months per subject ]
    Defined as the time from the date of the first dose of study drug until death due to any cause.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Histologically confirmed FL.
  • Documented CD20+ FL.
  • Relapsed or refractory to any prior rituximab-containing regimen.
  • Previously treated with a maximum of 4 cancer-directed treatment regimens.
  • At least 1 measurable lesion > 1.5 cm in at least 1 dimension by computed tomography or magnetic resonance imaging.
  • Must be willing to undergo an incisional or excisional lymph node biopsy of accessible adenopathy or provide the most recent, available archived tumor biopsy.
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2.

Exclusion Criteria:

  • Clinical evidence of transformation to a more aggressive subtype of lymphoma or Grade 3B FL.
  • History of central nervous system lymphoma (either primary or metastatic).
  • Allogeneic stem cell transplant within the last 6 months, or active graft-versus-host disease following allogeneic transplant or autologous stem cell transplant within the last 3 months before the date of the first dose of study drug administration.
  • Use of any potent cytochrome P450 3A4 inhibitors or inducers within 14 days or 5 half-lives (whichever is longer) before the first dose of study drug.
  • Prior treatment with a selective PI3Kδ inhibitor or a pan PI3K inhibitor.

  • Prior treatment with bendamustine (within 12 months of the start of study treatment). Subjects with prior bendamustine treatment (> 12 months before the start of study treatment) are eligible if they meet the following criteria:

    • Did not discontinue because of tolerability concerns.
    • Achieved either partial or CR to the bendamustine regimen of at least 12 months in duration before relapse/progression.
    • Experienced progression following a regimen containing an alkylating agent.
  • Received prior obinutuzumab.
  • Received rituximab within 4 weeks of study start.
  • Prior treatment-related toxicities that have not resolved to ≤ Grade 1 before the date of study drug administration except for stable chronic toxicities (≤ Grade 2) not expected to resolve (eg, stable Grade 2 peripheral neurotoxicity).
  • Received any prior monoclonal antibody (except an anti-CD20 antibody) within 90 days before the date of study start.
  • History of severe allergic or anaphylactic reactions to monoclonal antibody therapy (eg, subjects in whom re-administration with rituximab would be contraindicated for safety reasons).
