A Phase 1b/2a Basket Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Efficacy of Combination Therapy With the Anti CD19 Monoclonal Antibody Tafasitamab and the PI3Kδ Inhibitor Parsaclisib in Adult Participants With Relapsed/Refractory Non Hodgkin Lymphoma or Chronic Lymphocytic Leukemia

Number of Participants With Any Treatment-emergent Adverse Event (TEAE )

时间窗: up to 1092 days

An adverse event (AE) is any untoward medical occurrence associated with the use of a drug in humans, whether or not it is considered drug related. An AE can therefore be any unfavorable or unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study treatment. A TEAE is any AE either reported for the first time or the worsening of a pre-existing event after the first dose of study drug until 90 days after the last dose of study drug.

Number of Participants With Any ≥Grade 3 TEAE

时间窗: up to 1092 days

An AE is any untoward medical occurrence associated with the use of a drug in humans, whether or not it is considered drug related. A TEAE is any AE either reported for the first time or the worsening of a pre-existing event after the first dose of study drug until 90 days after the last dose of study drug. The severity of AEs was assessed using CTCAE v5.0 Grades 1 through 5. Grade 1: mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; treatment not indicated. Grade 2: moderate; minimal, local, or noninvasive treatment indicated; limiting age-appropriate activities of daily living. Grade 3: severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care activities of daily living. Grade 4: life-threatening consequences; urgent treatment indicated. Grade 5: fatal.

Number of Participants With Dose-limiting Toxicities (DLTs)

时间窗: up to 28 days

A DLT was defined as the occurrence of any protocol-defined toxicity up to and including Day 28 (Cycle 1/Day 28), except those with a clear alternative explanation.

Objective Response Rate Based on Investigator Assessment: Percentage of Participants With CR/CMR or PR/PMR According to Lugano Criteria for NHL and International Working Group for Chronic Lymphocytic Leukemia (iwCLL) Criteria for CLL

时间窗: up to 1002 days

Lugano complete response/complete metabolic response (CR/CMR): target nodes/masses of lymph nodes/extralymphatic sites (LNs/ELSs) regressed to ≤1.5 cm; no non-measured lesions; organ enlargement regressed to normal; no new lesions (NNLs); normal bone marrow. Lugano partial response/partial metabolic response (PR/PMR): LNs/ELSs, ≥50% decrease in the product of perpendicular diameters sum for multiple lesions; no/regressed non-measured lesions, no increase; organ enlargement; NNLs. iwCLL CR: no LNs ≥1.5 cm; spleen size \<13 cm/liver size normal; no constitutional symptoms; normal circulating lymphocyte count (CLC); ≥100 × 10\^9 platelets/L; hemoglobin ≥11 g/dL; normocellular, no CLL cells, no B-lymphoid nodules in marrow. iwCLL PR decrease of ≥50% in lymph nodes, liver and/or spleen, and CLC from baseline; constitutional symptoms; ≥100 × 10\^9 platelets/L or increase of ≥50% over baseline in platelet count and hemoglobin; presence of CLL cells, or of B-lymphoid nodules, or not done.
