Details and patient eligibility

About

This first-in-human (FIH) trial is designed to assess the safety, feasibility and preliminary efficacy of a single intravenous (IV) dose of SynKIR-310 administered to participants with relapsed/refractory B-NHL.

Full description

This is a Phase 1, FIH, multicenter, open-label study of a single infusion of SynKIR-310 in participants with relapsed/refractory B-NHL.

Up to 18 participants, regardless of subtypes of B-NHL, who meet the eligibility criteria, will be treated in the study.

2 cohorts of 3 to 6 participants per cohort will be assessed to determine the safety and feasibility of treatment with SynKIR-310. Doses will be escalated across 2 cohorts to determine a Recommended Phase 2 Dose (RP2D).

Once the RP2D has been determined, a dose expansion group will enroll additional participants regardless of subtypes of B-NHL at the RP2D to further characterize the safety, feasibility and preliminary efficacy of SynKIR-310 in treating B-NHL.

Must have refractory or relapsed disease after receiving 2 prior lines of therapies.
If relapsed/refractory post-auto-SCT, then must have undergone auto-SCT at least 6 months prior to enrollment.
If relapsed/refractory disease after allogeneic stem cell transplant (allo SCT) then must have undergone allo-SCT at least 6 months prior to enrollment and without evidence of graft versus host disease.
Measurable disease at time of enrollment: At least one measurable lesion per Lugano Response Criteria (Cheson et al., 2014).

Exclusion criteria

Previously treated with any investigational agent within 30 days prior to screening.
Adequately treated non-melanoma skin cancer such as basal cell or squamous cell carcinoma
Carcinoma-in-situ (e.g., cervix, bladder, breast) treated curatively and without evidence of recurrence for at least 3 years prior to enrollment.
Any other malignancy which has been completely treated and remains in complete remission for ≥ 5 years prior to enrollment. Completely treated prostate cancer with prostate-specific antigen (PSA) level < 1.0 may also be permitted.
Known immunodeficiency disease.
History or presence of active or clinically relevant primary central nervous system (CNS) disorder, such as seizure, encephalopathy, cerebrovascular ischemia/hemorrhage, cerebellar disease, or any autoimmune disease with CNS involvement. For primary CNS disorders that have recovered or are in remission, participants without recurrence within 2 years of planned study enrollment may be included.
