In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up of hormone level assessment is she considered not of childbearing potential.
  • Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, must use highly effective contraception during study treatment and for 4 months after study discontinuation. Highly effective contraception is defined as either
  • True abstinence: When this is the line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g. calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception
  • Sterilization: Surgical bilateral oophorectomy, with or without hysterectomy, or tubal ligation at least six weeks prior to study enrollment.

  • Use of a combination of any two of the following:
  • Placement of an intrauterine device (IUD) or intrauterine system (IUS)
  • Barrier methods of contraception: Condom or occlusive cap (diaphragm or cervical vault caps) with spermicidal form/gel/film/cream/vaginal suppository
  • Women of child-bearing potential must have one negative serum pregnancy tests at screening
  • In addition to having a negative pregnancy test confirmed at screening, all female participants of child bearing potential must have a negative pregnancy test confirmed within 48 hours prior to dosing with the study drug.
  • Men:
  • Fertile males, defined as all male subjects physiologically capable of conceiving offspring, must use a condom during study treatment and for 12 months after study discontinuation and should not father a child in this period.
  • Female partner of a male study subject should use a highly effective method of contraception while the male partner is receiving the study agent and for 12 months after the final dose of the study therapy.
  • Inclusion of women, minorities or other underrepresented populations
  • Ibrutinib and epcoritamab are not known to differentially affect subpopulations, including women, minorities, or other underrepresented groups. The eligibility and exclusion criteria are not expected to differentially impact recruitment or retention of these subpopulations.
  • Covid-19 eligibility criteria
  • Subject has no known active severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. If a subject has signs/symptoms suggestive of SARS-CoV-2 infection or have had recent known exposure to someone with SARS-CoV-2 infection, the subject must have a negative molecular (e.g., PCR) test, or 2 negative antigen test results at least 24 hours apart, to rule out SARS-CoV-2 infection.
  • Subjects who do not meet SARS-CoV-2 infection eligibility criteria must be screen failed and may only rescreen after they meet the following SARS-CoV-2 infection viral clearance criteria:
  • No signs/symptoms suggestive of active SARS-CoV-2 infection
  • Negative molecular (e.g., PCR) result or 2 negative antigen test results at least 24 hours apart
  • Given the ongoing COVID-19 pandemic, selected non-live vaccines (e.g. mRNA, non-replicating viral vector, protein subunit, etc.) to prevent SARS-CoV-2 infections may be administered during screening or the treatment period, as long as components of the vaccine are not contraindicated. COVID-19 vaccines are permitted and strongly recommended.
  • The decision to receive a locally available vaccine should be based on local guidance and an individual discussion between the treating physician and the subject.
  • The potential impact of epcoritamab on SARS-CoV-2 vaccination is unknown. Therefore, study drug should be administered as follows:
  • The first dose of study drug, when possible, is preferred to be given at least 14 days from SARS-CoV-2 vaccine administration.
  • A minimum period of 3 days must occur between the administration of an appropriate COVID-19 vaccine and the administration od epcoritamab (to avoid overlapping AEs).
  • Note: The above guidance applies to all SARS-CoV-2 vaccine doses given as part of the complete vaccination course.
  • These recommendations may be subject to change based on the evolving knowledge around the use of SARS-Cov-2 vaccines in subjects with recurrent/refractory DLBCL or cFL and as more data are collected in real-world scenarios and clinical trials.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ibrutinib and Epcoritamab in people with Primary Central Nervous System Lymphoma (PCNSL) and Primary Central Nervous System Lymphoma, run by Memorial Sloan Kettering Cancer Center at 8 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 50 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 14 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Christian Grommes, MD (212-610-0344, grommesc@mskcc.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of dose limiting toxicities/DLTs (time frame: 8 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jul 2026.
