EPKINLY delivered an ORR of 61%, with 38% of
patients achieving a deep response of CR1

61% of patients had a response (n=90/148; 95% CI, 53-69), 38% of patients had a complete response (n=56/148; 95% CI, 30-46), and 23% of patients had a partial response (n=34/148; 95% CI, 17-31). Median DOR was 15.6 months (n=90/148; 95% CI, 9.7 months-NR).

ORR, CR, and PR rates observed across additional subgroups2*

The efficacy of EPKINLY was evaluated in EPCORE NHL-1, an open-label, multicohort, multicenter, single-arm trial in 148 patients with R/R DLBCL after 2 or more lines of systemic therapy.

Patients aged <65 years (n=74) had a 53% overall response rate (95% CI, 41-64) (34% CR rate, 19% PR rate), patients aged 65 years to <75 years (n=45) had a 67% overall response rate (95% CI, 51-80) (38% CR rate, 29% PR rate) and patients aged ≥75 years (n=29) had a 72% overall response rate (95% CI, 53-87) (48% CR rate, 24% PR rate).
Patients with de novo DLBCL (n=97) had a 61% overall response rate (95% CI, 50-71) (37% CR rate, 24% PR rate), transformed DLBCL (n=40) had a 68% overall response rate (95% CI, 51-81) (45% CR rate, 23% PR rate), primary refractory had a 52% overall response rate (95% CI, 41-62) (28% CR rate, 24% PR rate) and double-hit/triple-hit (n=17) had a 41% overall response rate (95% CI, 18-67) (24% CR rate, 17% PR rate).
CAR T-naïve patients (n=90) had a 67% overall response rate (95% CI, 56-76) (41% CR rate, 26% PR rate), Car T-exposed (n=58) had a 52% overall response rate (95% CI, 38-65) (33% CR rate, 19% PR rate), Car T-refractory (n=43) had a 42% overall response rate (95% CI, 27-58) (26% CR rate, 16% PR rate).
Patients with 2 prior lines of treatment had a 61% overall response rate (95% CI, 45-76) (34% CR rate, 27% PR rate), with 3 prior lines of treatment had a 62% overall response rate (95% CI, 47-76) (38% CR rate, 24% PR rate) and with 4 or more prior lines of treatment had a 59% overall response rate (95% CI, 46-72) (41% CR rate, 18% PR rate).

Data Limitation: Study was not powered to evaluate these prespecified subgroups. Data are exploratory and descriptive in nature. No formal inferences can be drawn.

In overall responders (61%, n=90/148), EPKINLY delivered durable responses in heavily pretreated 3L+ DLBCL, NOS patients1

In overall responders (61%, n=90/148): Rapid, 1.4 months median time to response (range 1.0-8.4). Durable, mDOR 15.6 months (95% CI, 9.7 mo-NR). Sustained, 63% still responding at 9 months (estimated; 95% CI, 52-72).
  • In the efficacy population of 148 patients, the median number of prior therapies was 3 (range: 2-11), with 2 prior (30%), 3 prior (30%), and 4+ prior (40%). Prior therapies: autologous HSCT (18%), CAR T (39%). Refractory to last therapy (82%). Refractory to CAR T (29%)

Long-term follow-up: Safety data3

  • With a median follow-up of 31 months, observations were consistent with the known epcoritamab safety profile. Discontinuation due to an adverse reaction occurred in 6% of patients
  • Serious infections were reported in 31% of patients. Serious infections ≥5% were COVID-19 events§ (15% of patients). Fatal infections occurred in 12 patients, of which 9 were COVID-19 events§

No inference can be drawn from this data set. Follow-up analysis is exploratory and data are descriptive in nature.
The Kaplan-Meier estimates may be unreliable at the tail end of the curve due to a smaller number of patients at risk.
