ClinConnect Summary

This clinical trial is studying a new treatment approach for patients with relapsed or difficult-to-treat aggressive B-cell lymphomas, such as Diffuse Large B-cell Lymphoma (DLBCL). The trial is testing a medication called Epcoritamab, which will be combined with a standard chemotherapy regimen and followed by a procedure called autologous stem cell transplantation (ASCT). The main goals are to see if adding Epcoritamab can help more patients achieve complete remission (where the cancer is no longer detectable) before the transplant, and to evaluate the safety and effectiveness of continuing Epcoritamab after the transplant.

To participate in this trial, candidates must be at least 18 years old and have a confirmed diagnosis of one of the specified types of lymphoma that has not responded to previous treatment. They should also meet certain health criteria, such as having measurable disease and adequate organ function. If they join, participants will undergo three phases: receiving Epcoritamab with chemotherapy, then having the stem cell transplant, and finally continuing Epcoritamab for additional cycles. It’s important for potential participants to discuss with their doctors if this trial is the right option for them, considering their specific health conditions and treatment history.

  • 12. Resolution of toxicities from prior therapy to a grade that does not contraindicate trial participation in the opinion of the investigator
  • 13. If receiving glucocorticoid treatment at screening, treatment must be tapered down and administered with a maximum of 25 mg daily in the last 14 days before the first dose of Epcoritamab
  • 14. Before the first dose of Epcoritamab, during the trial and for 12 months after last administration of Epcoritamab, a woman must be either:
  • 1. Not of childbearing potential, defined as: premenarchal; postmenopausal (greater than 45 years of age with amenorrhea for at least 12 months or any age with amenorrhea for at least 6 months and a serum follicle stimulating hormone (FSH) level greater than 40 IU per L or milli-International unit (mIU) per mL); permanently sterilized (e.g., bilateral tubal occlusion \[which includes tubal ligation procedures as consistent with local regulations\], hysterectomy, bilateral salpingectomy, bilateral oophorectomy); or otherwise be incapable of pregnancy
