      Trial Summary

      This is a Phase Ib, open-label, multicenter, global study designed to assess the safety and tolerability of RO6870810 as monotherapy and in combination with daratumumab in participants with relapsed/refractory multiple myeloma. Each treatment cycle will be 21 days in length. There are two parts to this study. A dose-escalation phase (Part I) will be used to evaluate the safety and tolerability and dose limiting toxicities, and to establish the maximum tolerated dose (MTR)/optimum biological dose (OBD) of RO6870810 when given as monotherapy or in combination with daratumumab. A dose-expansion phase (Part II) will further characterize the safety, tolerability and activity of RO6870810 as monotherapy or in combination with daratumumab at the defined expansion dose-levels.

      Eligibility Criteria

      All Gender
      ≥ 18 Years Age
      No Healthy Volunteers
      Inclusion Criteria
      • Performance status </=2 on the Eastern Cooperative Oncology Group (ECOG) scale
      • Life expectancy > 3 months
      • Relapsed or refractory multiple myeloma. Participants with primary refractory myeloma only allowed in dose-escalation phase of the study.
      • Prior treatment: Treated with at least three prior lines of multiple myeloma therapy including a proteasome inhibitor and an immuno modulatory agent or who are double refractory to a proteasome inhibitor and an immuno modulatory agent. Prior anti-CD38 antibody (e.g., daratumumab, isatuximab) treatment is acceptable only for participants receiving monotherapy treatment.
      • Prior treatment: Treated with two or more lines of prior therapy, with disease refractory to both a proteasome inhibitor and an immunomodulatory agent, and disease progression (as defined by International Myeloma Working Group (IMWG) criteria) following treatment with an anti-CD38 monoclonal antibody given as monotherapy or in combination therapy. The most recent treatment regimen must have contained an anti-CD38 monoclonal antibody.
      • Treatment with prior autologous transplant is permitted
      • Documented diagnosis of symptomatic multiple myeloma, as defined by the IMWG
      • Measurable disease defined as at least one of the following: serum M-protein >/=1 grams/deciliter (g/dL), urine M-protein >/= 200 milligrams/24 hours (mg/24h), serum free light chain (SFLC) assay: involved SFLCs >/= 10 mg/dL (>/= 100 mg/L) and an abnormal SFLC ratio (<0.26 or >1.65).
      • Female participants of childbearing potential must have a negative serum pregnancy test within the 7 days prior to the first study drug administration.
      • For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods that result in a failure rate of < 1% per year during the treatment period and for at least 2 months after the last dose of RO6870810 as monotherapy, or for at least 3 months after the last dose of daratumumab.
      • For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures and agreement to refrain from donating sperm, as defined: With female partners of childbearing potential or pregnant female partners, men must remain abstinent or use a condom during the treatment period and for at least 4 months after the last dose of RO6870810 as monotherapy, or for at least 3 months after the last dose of daratumumab.
      Exclusion Criteria
      • Plasma cell leukemia defined as peripheral plasma cell count > 2000/cubic millimeter (mm^3)
      • For expansion cohorts only: Primary refractory multiple myeloma defined as disease that is non-responsive in participants who have never achieved a minimal response or better with any therapy
      • History of other malignancy within 2 years prior to screening, except for ductal carcinoma in situ not requiring chemotherapy, appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, low-grade, localized prostate cancer (Gleason score </= 7) not requiring treatment or appropriately treated Stage I uterine cancer
      • POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein and skin changes)
      • Current or prior disease or treatment that could compromise protocol objectives in the opinion of the Investigator and/or the Sponsor
      • Pregnant or breastfeeding female.
      • Consumption of agents which strongly inhibit CYP3A4 enzyme, within 7 days prior to the first dose of study treatment and during the study.
      • Consumption of agents which strongly induce CYP3A4 enzyme, within 14 days prior to the first dose of study treatment and during the study.
      • Surgery within 21 days prior to study entry.
      • Prior treatment with small molecule BET family inhibitor or receiving steroids >the equivalent of 10mg prednisone daily
      • participants who are currently receiving any other investigational agent or have received an investigational agent within 30 days or 5 half-lives, whichever is longer, prior to study entry
      • Uncontrolled cancer pain
      • Prior anti-cancer therapy (chemotherapy, targeted agents, radiotherapy, and immunotherapy) within 14 days except for alkylating agents (e.g., melphalan) within 28 days.
