PLYCOM: This study is evaluating multiple treatment combinations in people with multiple myelomaA Platform Study Evaluating the Safety and Efficacy of Multiple Treatments in Patients With Multiple Myeloma

Clinical summary

Summary

This study is designed with the flexibility to open new treatment substudies as new treatments become available.

At present (April 2024) there are two substudies open:

Cevos + Len substudy (SS) 2 (DIRAC):

This stubstudy will explore the combination of cevostamab and lenalidomide as post-transplant maintenance therapy in participants with multiple myeloma (MM) with high-risk cytogenetic features who experienced at least a partial response (PR) after induction.

This is a dose escalation and expansion study. In the pre-phase, participants will receive 2 step-up doses and a target dose of cevostamab given intravenously (IV). The step-up dose will be given on Day(D)1 and D4. The target dose will be given on D8. Subsequently the target dose will be administered on D1 and D15 for cycles 1-6 and D1 of cycle 7 onwards. Each cycle is 28 days. Lenalidomide will be administered by mouth (PO) on a 28-day cycle.

During the dose expansion phase, cevostamab will be administered following the same dosing schedule as the dose escalation phase. The target dose will be determined after the escalation phase. Lenalidomide will be administered PO on a 28-day cycle.

Cevostamab + Iberdomide SS4 (CHAWLA):

This substudy will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of the combination of cevostamab and iberdomide in participants with relapsed/refractory MM who have received at least three prior lines of therapy, including a PI, an IMiD, and an anti-CD38 monoclonal antibody. 

This is a dose escalation and expansion study. In the pre-phase, participants will receive 2 step-up doses and a target dose of cevostamab administered via IV. The step-up dose will be given on D1 and D4. The target dose will be given on D8. Subsequently the target dose will be administered on D1 of each cycle, every 3 weeks (Q3W). Each cycle is 21 days. Iberdomide will be administered PO on a 21-day cycle.

During the dose expansion phase, cevostamab will be administered following the same dosing schedule as the dose escalation phase. The target dose will be determined after the escalation phase. Iberdomide will be administered PO on a 21-day cycle.

  • Resolution of AEs from prior anti-cancer therapy to Grade <=1
  • Agreement to undergo scheduled assessments and procedures

Additional Inclusion Criteria for SS2:

  • Completion of planned induction therapy and achievement of at least a partial response (PR)
  • Autologous Stem Cell Transplant (SCT) within 100 days prior to first study treatment and the absence of progressive disease
  • Cytogenetic high-risk features at diagnosis
  • Treatment with any investigational medicinal products, systemic cancer therapies, immunotherapies received previously in CO43923 (any arms) within 5 half-lives or 3 weeks whichever is the shortest
  • Agreement to comply with all local requirements of the lenalidomide risk minimization plan, which includes the global pregnancy prevention program
  • For female participants of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraception
  • For male participants: agreement to remain abstinent (refrain from heterosexual intercourse) or use a condom even if they have had a prior vasectomy, and agreement to refrain from donating sperm

Additional Inclusion Criteria for SS4:

  • Previously exposed to at least a PI, an IMiD, and an anti-CD38 antibody for the treatment of R/R MM for whom no suitable SOC therapy options are available

Exclusion

  • Inability to comply with protocol-mandated hospitalization and procedures
  • History of confirmed progressive multifocal leukoencephalopathy
  • History of other malignancy within 2 years prior to screening
  • Current or past history of central nervous system (CNS) disease
  • Significant cardiovascular disease that may limit a participant's ability to adequately respond to a CRS event
  • Symptomatic active pulmonary disease or requiring supplemental oxygen
  • Known active bacterial, viral, fungal, mycobacterial, parasitic, or other infection at study enrollment, or any major episode of infection requiring treatment with IV antibiotics where the last dose of IV antibiotics was given within 14 days prior to first study treatment
