Celgene Corporation (NASDAQ: CELG) today announced the first clinical results evaluating iberdomide (CC-220) in combination with dexamethasone in patients with relapsed and refractory multiple myeloma from the ongoing phase 1/2 CC-220-MM-001 study during an oral presentation at the 2019 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.
As of April 2019, 66 patients at a median age of 65 received the iberdomide plus dexamethasone combination, with iberdomide being administered in 8 incremental doses ranging from 0.3 mg to 1.3 mg. Escalating doses of iberdomide were given on days 1 through 21 in combination with dexamethasone (40 mg; 20 mg in patients older than 75) on days 1, 8, 15, and 22 of each 28-day cycle. Patients had a median of five prior multiple myeloma treatment regimens, which could have included stem cell transplant, immunomodulatory drugs including lenalidomide and pomalidomide, proteasome inhibitors and daratumumab.
Grade 3-4 adverse events (AE) reported included neutropenia (29%), infection (26%), anemia (24%), thrombocytopenia (12%), pulmonary embolism (1.5%) and peripheral sensory neuropathy (1.5%). Six patients (9%) discontinued treatment due to adverse events.
Of the 66 patients who received the iberdomide plus dexamethasone combination, 59 were evaluable for response. The overall response rate was 32% (19/59), with 29% (17/59) achieving a partial response and two patients achieving a very good partial response.
Patients (n=51) who were refractory to IMiD ® compounds, which included lenalidomide and pomalidomide, had an overall response rate of 35% (18/51) with 33% (17/51) of patients achieving a partial response and one patient achieving a very good partial response. Further, patients who were refractory to both daratumumab and pomalidomide (n=27) had an overall response rate of 29% (8/27), with 25% (7/27) achieving a partial response and one patient achieving a very good partial response. Maximum tolerated dose and the recommended phase 2 dose have not yet been determined.
