  • Exception: Monoclonal and bispecific antibodies is acceptable
  • Prior therapy with golcadomide ≤ 4 weeks prior to registration
  • Prior autologous stem cell transplantation (SCT) ≤ 3 months prior to registration. If subject had autologous SCT > 3 months prior to the start of registration, any treatment-related toxicity is unresolved (grade > 1)
  • Major surgery ≤ 3 weeks prior to registration
  • Chemotherapy ≤ 2 weeks prior to registration
  • Concomitant radiation therapy; local palliative radiotherapy is permitted
  • Co-morbid systemic illnesses or other severe concurrent disease or cancer which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens

  • Symptomatic congestive heart failure
  • History of myocardial infarction ≤ 6 months, or congestive heart failure requiring use of ongoing maintenance therapy for life-threatening ventricular arrhythmias
  • Unstable angina pectoris
  • Cardiac arrhythmia
  • Uncontrolled intercurrent non-cardiac illness including, but not limited to:
  • Ongoing or active infection

  • Any other conditions that would limit compliance with study requirements

  • Subject has known chronic active hepatitis B or C virus (HBV/HCV) infection
  • Exception: Patients with HBV and an undetectable viral load who are on suppressive therapy and/or those with HCV and an undetectable viral load are allowed
  • Concurrent administration of strong or moderate CYP3A4/5 inhibitors and inducers within 14 days or 5 half-lives, whichever is longer before the study treatment administration

  • Exception: Corticosteroids are allowed
  • Active second malignancy requiring treatment that would interfere with the assessment of the response of the primary cancer or interpretation of the safety of this protocol therapy
  • History of deep venous thrombosis/embolism, threatening thromboembolism or known thrombophilia. Patients with a history of deep vein thrombosis (DVT)/pulmonary embolism (PE) or thrombophilia may still participate if they are willing to be on full anticoagulation during treatment. Full anticoagulation is defined as Warfarin, factor X inhibitors, or low molecular weight heparin at therapeutic doses. The rationale for this requirement is that golcadomide therapy is associated with an increased risk of thrombosis. Patients with no history of DVT/PE or thrombophilia are not required to take anticoagulation and/or anti-platelet prophylaxis
  • NOTE: If a patient develops a thrombotic event, they must be able and willing to receive anticoagulation therapy with aspirin 81-325 mg daily prophylaxis, low molecular weight heparin, factor X inhibitors or Warfarin. This is due to an increased risk of thrombosis in patients treated with golcadomide without prophylaxis
  • Live COVID-19 vaccine administered ≤ 28 days prior to registration

The treatment

How it is intended to work

This is how the treatment is meant to work. Whether it helps, and how safe it is, is what this trial is testing.

golcadomide. A modulator of the E3 ubiquitin ligase complex containing cereblon (CRL4-CRBN E3 ubiquitin ligase), with potential immunomodulating and antineoplastic activities. Upon administration, golcadomide specifically binds to cereblon (CRBN), thereby affecting the ubiquitin E3 ligase activity, and targeting certain substrate proteins for ubiquitination. This induces proteasome-mediated degradation of certain transcription factors, some of which are transcriptional repressors in T cells. This leads to modulation of the immune system, including activation of T lymphocytes, and downregulation of the activity of other proteins, some of which play key roles in the proliferation of certain cancer cell types. CRBN, the substrate recognition component of the CRL4-CRBN E3 ubiquitin ligase complex, plays a key role in the ubiquitination of certain proteins. NCI Drug Dictionary

The study

Treatment groups

Na · Single Group · masking: None

Treatment (golcadomide, rituximab) (Experimental)

ELIGIBLE FOR CAR-T: Patients receive golcadomide orally (PO) once daily (QD) on days 1-14 of each cycle and rituximab intravenously (IV) on days 1, 8, 15 and 22 of cycle 1 and then on day 1 of all subsequent cycles. After 1 cycle, patients undergo leukapheresis and receive an additional cycle of golcadomide and rituximab (bridging therapy) prior to undergoing standard of care CAR-T therapy. Patients may also receive optional bridging therapy with golcadomide and rituximab per physician choice (1-2 cycles) prior to undergoing standard of care CAR-T therapy. INELIGIBLE FOR CAR-T: Patients receive golcadomide PO QD on days 1-14 of each cycle and rituximab IV on days 1, 8, 15 and 22 of cycle 1 and then on day 1 of all subsequent cycles. Patients receive golcadomide PO QD on days 1-14 of each cycle and rituximab IV on day 1 of each cycle. Patients ineligible for CAR-T after 5 cycles, receive golcadomide PO QD on days 1-14 of each cycle. See Detailed Description for more info.
