cc-122 and Lymphoma--Non-Hodgkin

Non-Hodgkin lymphoma (NHL) treated with chemoimmunotherapy has limited efficacy in some patients, resulting in relapsed or refractory disease. Avadomide (CC-122) is a novel cereblon-binding agent that exhibits antilymphoma and immune-modulation activities with a biological profile distinct from similar agents, such as lenalidomide. This phase I multicenter study evaluated avadomide in Japanese patients with advanced solid tumors or NHL. Fourteen patients with NHL and one with a solid tumor (esophageal carcinoma), were enrolled in four dose-escalation cohorts using a 3 + 3 design. Primary endpoints included safety, dose-limiting toxicities (DLT), maximum-tolerated dose and/or recommended phase II dose (RP2D), and pharmacokinetics. Secondary endpoints included overall response rate (ORR) and duration of response. One patient with NHL experienced DLT, which included face edema, pharyngeal edema, and tumor flare (all grade 1) that led to a dose reduction. Eleven patients had grade ≥3 treatment-emergent adverse events, most frequently decreased neutrophil count (33%) and decreased lymphocyte count (20%). The ORR in patients with NHL (n = 13) was 54%, including four complete and three partial responses. The best response for the solid tumor patient was progressive disease. Avadomide dose intensity was consistent across cohorts, and the 3-mg dose given five consecutive days/week was established as the RP2D. This phase I study identified a tolerable dose of avadomide, with an acceptable toxicity profile and clinically meaningful efficacy in Japanese patients with previously treated NHL.

Avadomide is a novel, small-molecule therapeutic agent that modulates cereblon E3 ligase activity and exhibits potent antitumor and immunomodulatory activities. This first-in-human phase I study (NCT01421524) evaluated the safety and clinical activity of avadomide in patients with advanced solid tumors, non-Hodgkin lymphoma (NHL), and multiple myeloma.. Thirty-four patients were treated with avadomide in 7 dose-escalation cohorts using a 3 + 3 design (0.5-3.5 mg, 28-day continuous dosing cycles). The primary objectives were to determine the dose-limiting toxicity (DLT), nontolerated dose (NTD), maximum tolerated dose (MTD), recommended phase II dose, and pharmacokinetics of avadomide. The secondary objective was to determine preliminary avadomide efficacy. Exploratory objectives included evaluation of pharmacodynamic effects of avadomide.. DLTs were reported in 2 patients, and grade ≥3 treatment-emergent adverse events (TEAEs) occurred in 14 patients (41%). The most common TEAEs (≥15%) were fatigue, neutropenia, and diarrhea. The NTD and MTD were 3.5 and 3.0 mg, respectively. Of 5 patients with NHL, 1 achieved a complete response, and 2 had partial responses. Although no objective responses were observed in patients with solid tumors, 5 of 6 patients with brain cancer experienced nonprogression of ≥6 months. A dose-dependent relationship between Aiolos degradation in peripheral B and T cells occurred within 5 hours of the first dose of avadomide administered, starting at 0.5 mg.. Avadomide monotherapy demonstrated acceptable safety and favorable pharmacokinetics in patients with solid tumors, NHL, and multiple myeloma. In addition, 3 objective responses were observed in NHL.
