Safety, Pharmacodynamics, Pharmacokinetics, and Efficacy of GS-9901 in Adults With Relapsed or Refractory Follicular Lymphoma, Marginal Zone Lymphoma, Chronic Lymphocytic Leukemia, or Small Lymphocytic Lymphoma

• Status: Terminated
• Trial end date: 2015-08-01
• Target enrollment: 0
• Participant gender: All

Summary

This study will evaluate the safety and tolerability of GS-9901 monotherapy in adults with follicular lymphoma (FL), marginal zone lymphoma (MZL), chronic lymphocytic leukemia (CLL), or small lymphocytic lymphoma (SLL). The study will also characterize the pharmacokinetic (PK) profile of GS-9901, determine the appropriate dosing regimen of GS-9901 for use in future clinical trials, and to evaluate the efficacy of GS-9901 monotherapy in adults with FL, MZL, CLL, or SLL.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Gilead Sciences

Criteria

Inclusion Criteria:

• Diagnosis of FL, MZL, SLL, or CLL (meeting International Workshop on CLL [IWCLL] Criteria, 2008) as documented by medical records and with histology based on criteria established by the World Health Organization

• FL Grades 1, 2, or 3a

• SLL with absolute lymphocyte count of < 5 x 10^9/L at initial diagnosis

• MZL (splenic, nodal, or extra-nodal)

• Prior treatment for FL or CLL/SLL with ≥ 1 prior chemotherapy-based or immunotherapy-based regimen with no approved therapies available

• Presence of radiographically measurable lymphadenopathy or extra nodal lymphoid malignancy

• All acute toxic effects of any prior antitumor therapy resolved to Grade ≤1 before the start of study therapy (with the exception of alopecia [Grade 1 or 2 permitted], or bone marrow parameters [any of Grade 1, 2, or 3 permitted)

• Eastern Cooperative Oncology Group (ECOG) ≤ 2

• Able to provide written informed consent

Exclusion Criteria:

• Evidence of ongoing systemic bacterial, fungal, or viral infection at the time of start of study therapy

• Ongoing drug-induced pneumonitis

• Ongoing inflammatory bowel disease

• History of prior allogeneic bone marrow progenitor cell or solid organ transplantation

• History of prior therapy with any inhibitor of serine/threonine kinase (AKT), Bruton tyrosine kinase (BTK), Janus kinase (JAK), mammalian target of rapamycin (mTOR), phosphatidylinositol 3-kinase (PI3K), or spleen tyrosine kinase (SYK)

• Ongoing immunosuppressive therapy, including systemic corticosteroids for treatment of lymphoid malignancy
