Epcoritamab Plus Lenalidomide and Rituximab in Follicular Lymphoma: Lori A. Leslie, MD
Lori A. Leslie, MD, of John Theurer Cancer Center at Hackensack Meridian Health and Hackensack Meridian School of Medicine, reported 3-year data from arms 6 and 7 of the phase 1b/2 EPCORE NHL-2 trial (NCT04663347) evaluating epcoritamab-bysp (Epkinly) plus rituximab (Rituxan) and lenalidomide (Revlimid; R2) and epcoritamab maintenance in patients with previously untreated follicular lymphoma. In arm 6, epcoritamab plus R2 (n = 41) induced an ORR of 95%, which comprised a CR rate of 88% and a partial response (PR) rate of 7%. Of those who completed treatment in CR (n = 21), 95% maintained response, and the median duration of CR was not reached (NR). The median time to next treatment was also NR. Moreover, approximately 95% (95% CI, 83%-100%) of patients had not received a new anti-lymphoma treatment at 33 months. Serious infections occurred in 32% of patients, neutropenia rates were highest in the first 24 weeks, and cytokine release syndrome (CRS) cases were all grade 1 or 2.
Efficacy of Anitocabtagene Autoleucel in R/R Multiple Myeloma: Krina K. Patel, MD, MSc
Krina K. Patel, MD, MSc, of The University of Texas MD Anderson Cancer Center, shared findings from the phase 2 iMMagine-1 trial (NCT05396885) of anitocabtagene autoleucel in patients with relapsed/refractory multiple myeloma, which were shared during the 2025 ASH Annual Meeting. The CAR T-cell therapy (n = 117) elicited an ORR of 96%, which included a very good partial response or better rate of 88% and stringent CR (sCR)/CR rate of 74% in this population. The median time to first response was 1.0 months (IQR, 1.0-1.9), the median time to best response was 4.8 months (IQR, 2.1-9.0), and the time to sCR/CR was 3.2 months (IQR, 2.0-9.2). The overall minimal residual disease (MRD) negativity rate (10-5 sensitivity level) was 95%, with a median time to MRD negativity of 1.0 month (range, 0.9-6.4), and MRD negativity sustained for at least 6 months for 83% of patients. At a 10-6 sensitivity level, the overall MRD negativity rate was 78%. The 24-month progression-free survival rate and overall survival rates were 61.7% (95% CI, 48.0%-72.8%) and 83.0% (95% CI, 70.7%-90.5%), respectively. The toxicity profile was noted to be predictable and manageable.
Efficacy of Frontline Blinatumomab Plus Ponatinib in Ph+ B-ALL: Hannah Goulart, MD
Hannah Goulart, MD, of The University of Texas MD Anderson Cancer Center, shared long-term data from a phase 2 trial (NCT03263572) investigating first-line blinatumomab (Blincyto) combined with ponatinib (Iclusig) in patients with Philadelphia chromosome–positive B-cell acute lymphoblastic leukemia. The regimen elicited an ORR of 97% with a CR rate of 95%. Ninety-seven percent of patients achieved MRD negativity, with 44% achieving negativity after one cycle of treatment. The median event-free survival and OS have not yet been reached; the 3-year rates were 78% and 89%, respectively. The most common toxicities that were at least grade 3 in severity included increased alanine aminotransferase level, increased lipase, febrile neutropenia, and pneumonia.
Azacitidine Plus Venetoclax and Gilteritinib in FLT3 Wild-Type AML: Sankalp Arora, MD
Sankalp Arora, MD, of The University of Texas MD Anderson Cancer Center, discussed data from a phase 2 study investigating azacitidine (Vidaza) paired with venetoclax (Venclexta) and gilteritinib (Xospata) for use in patients with newly diagnosed, adverse-risk, FLT3 wild-type AML. The regimen led to a composite CR (CRc) rate of 53% in all evaluable patients (n = 15), with CRc rates of 44% and 67% in those with (n = 9) and without (n = 6) TP53 mutations, respectively. Moreover, in those with treated secondary AML (n = 7) and those without (n = 8), the CRc rates with the combination were 29% and 75%, respectively. The median OS and relapse-free survival were NR. With regard to safety, the most frequently experienced grade 3 to 5 non-hematologic toxicities comprised infections, febrile neutropenia, and hypertension.
