Etentamig is a type of drug known as an immunotherapeutic drug. Immunotherapy is a form of cancer treatment that uses the immune system to attack cancer cells, similar to the way it attacks bacteria or viruses. This type of therapy works by activating immune cells circulating in your body. Simply put, immunotherapy is a tool to trigger your body to treat the cancer itself. Etentamig has been developed in a laboratory to make powerful ‘killer’ T-cells from your own immune system attack multiple myeloma cells in your body.
Etentamig is a ‘bispecific’ antibody, meaning that it interacts with two molecules in your body. One molecule is called B-Cell Maturation Antigen (BCMA) and is found on your multiple myeloma cells. The second is called CD3 and is present on your killer T-cells. When CD3 is engaged on a T cell, it turns the T-cell on and makes it kill whatever cell triggered the activation. Because Etentamig sticks very strongly to your myeloma cells, nearby T-cells should specifically attack your tumor cells.

Of 146 pts with RRMM who received etenta, 87 (60%) were male, median age (range) was 68 (40–87) years, median prior LoT were 4 (3–23), and median duration of follow-up was 13 (1–48) months (mo). ORR was achieved in 96 (66%) pts and ≥VGPR in 79 (54%) pts. Response rates across subgroups are reported in the Table. Median duration of response was not reached (NR) (NR–NR) among responders; Kaplan-Meier (KM) estimate at 12 mo was 71% (58.5%–80.5%). Median PFS (mPFS) was NR (8.7–NR) mo; KM estimate at 12 mo was 55% (44.9%–63.1%). Any grade and G3/4 treatment emergent adverse events (TEAEs) occurred in 145 (99%) pts and 116 (79%) pts. Most common G3/4 TEAEs (≥15%) were neutropenia (38%), anemia (23%), lymphopenia (25%), and thrombocytopenia (16%). Infections G3/G4 were reported in 32 (22%) pts; most common infections G3/G4 (≥5%) were pneumonia (12%) and sepsis (5%). TEAEs leading to etenta discontinuation were reported in 13 (9%) pts. Deaths from TEAEs were reported in 13 (9%) pts; 10 were not attributed to etenta treatment. In Arm A of Ph 1 study where 60mg Q4W was administered with SUD and modified dex as premedication, CRS incidence was 30% (4% G2; No ≥G3 events) with median time to CRS onset of 22.3 (5.5–29.6) hours; and median time to CRS resolution of 20.7 (1.8–131.7) hours. Conclusions: Etenta with SUD demonstrated a low CRS incidence, durable response, and tolerability in pts with heavily pretreated RRMM.
