To assess the efficacy of epcoritamab in evaluable R/R PCNSL subjects treated with lenalidomide and rituximab as measured by the best objective response rate (CR + CRu + PR) during the first 8 cycles (induction phase) according to the International for Primary CNS Lymphoma collaborative group (IPCG) recommendations (or International PCNSL collaborative group).
- Phase II and Phase III (Integrated)

Who can take part
You may be able to join if
- Subject (or their legally acceptable representative/trusted person) who understand and voluntarily signs and dates an informed consent form prior to any study-specific assessments/procedures being conducted.
- Adequate renal function: calculated by Cockcroft-Gault equation creatinine clearance > 40 ml/min. Subjects with calculated creatinine clearance > 40 and < 60ml/min lenalidomide dose will be adjusted.
- Adequate liver function: Serum total bilirubin level ≤ 2.0 mg/dl [34 μmol/L] (unless bilirubin rise is due to Gilbert’s syndrome) and serum transaminases (AST or ALT) ≤ 3 upper normal limits.
- Able to understand teratogenic risks of the treatment (Lenalidomide).
- Women of childbearing potential (WOCBP) should agree to use two reliable forms of contraception simultaneously or to practice complete abstinence from heterosexual contact during the following time periods related to this study: 1) for at least 28 days before starting study treatment, 2) while participating in the study, 3) dose interruptions, and 4) for at least 12 months after the final dose of rituximab, or for at least 12 months after the final dose of epcoritamab, or for at least 28 days after the final dose of lenalidomide . WOCBP should also agree to abstain from breastfeeding during study participation and for at least 4 months after discontinuation of all study treatments.
- WOCBP should have a negative serum (beta-hCG) pregnancy test at screening and a negative serum or urine pregnancy test before treatment administration on Day 1 of every cycle.
You likely can't join if
- T-cell lymphoma
- Any previous treatment with CAR-T therapy within 30 days prior to enrollment
- Receiving immunosuppressive therapy, including more than the equivalent of 20 mg of prednisolone daily, unless for control of lymphoma or intermittent prophylaxis/treatment of allergic reactions.
- Any previous treatment with a bispecific antibody targeting CD3 and CD20 and/or with lenalidomide, regardless of the time and duration
- Seizure disorder requiring anti-epileptic therapy unless related to lymphoma
- Vaccination with live, attenuated vaccines within 28 days prior of enrollment (except severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine). Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette–Guérin, and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (eg, FluMist®) are live attenuated vaccines and are not allowed. Experimental and/or nonauthorized SARS-CoV-2 vaccinations are not allowed.
