Study CC-93269-MM-001 is an open-label, Phase 1, dose escalation (Part A) and expansion (Part B), first-in-human clinical study of CC-93269 in subjects with relapsed and refractory multiple myeloma.

Official Title

A Phase 1, Open-label, Dose Finding Study of CC-93269, a BCMA X CD3 T Cell Engaging Antibody, in Subjects With Relapsed and Refractory Multiple Myeloma.


The dose escalation part (Part A) of the study will evaluate the safety and tolerability of escalating doses of CC-93269, administered intravenously (IV), to determine the maximum tolerated dose (MTD) and non-tolerated dose (NTD) of both the first dose and subsequent doses of CC-93269. The expansion part (Part B) will further evaluate the safety and efficacy of CC-93269 administered at or below the MTD in selected expansion cohorts in order to determine the recommended Phase 2 dose (RP2D). One or more dosing regimens may be selected for cohort expansion. All treatments will be administered in 28-day cycles for up to 2 years until confirmed disease progression, unacceptable toxicity, or subject/Investigator decision to withdraw.

  5. Subjects with clinically significant cardiac disease.
  6. Subject had a prior autologous stem cell transplant ≤ 3 month prior to starting CC-93269.
  7. Subject had a prior allogeneic stem cell transplant ≤ 12 month prior to starting CC-93269.
  8. Subject had a prior systemic cancer-directed treatments or investigational modalities ≤ 5 half-lives or 4 weeks prior to starting CC-93269, whichever is shorter.
  9. Subject had major surgery ≤ 2 weeks prior to starting CC-93269.
  10. . Subject is a pregnant or lactating female.

  14. . Subject has a history of concurrent second cancers requiring active, ongoing systemic treatment.
  15. . Subject has a history or presence of clinically relevant central nervous system (CNS) pathology.
  16. . Subject has any significant medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from participating in the study.
  17. . Subject has any condition (eg, active or uncontrolled infection) including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study.
