Participants will receive escalated doses of RO67870810 SC. RO6870810 will be escalated at a starting dose of 0.03 milligrams per kilogram (mg/kg) to a maximum of 0.85 mg/kg. Treatment will be administered in treatment cycles of either 21 days or 28 days and continued until PD, adverse events which justify treatment withdrawal, non-adherence, non-compliance, investigator decision, lost to follow-up, enrollment in other clinical study, or unacceptable toxicity.

Participants will receive RO6870810 at doses up to the MTD or up to the highest dose tested if the MTD is not defined. Treatment will be administered in treatment cycles of either 21 days or 28 days and continued until PD, adverse events which justify treatment withdrawal, non-adherence, non-compliance, investigator decision, lost to follow-up, enrollment in other clinical study, or unacceptable toxicity.

Participants will receive RO6870810 at different planned doses with a starting dose of 0.03 mg/kg to a maximum dose of 0.85 mg/kg SC on Days 1 to 14 in a 21-day treatment cycle or on Days 1 to 21 in a 28-day treatment cycle.

Clinical Trials

This is a Phase 1, non-randomized, dose-escalating, open label, multi-center study to be conducted in two parts (Part A and Part B). RO6870810 is a small molecule, non-covalent inhibitor of bromodomain and extra-terminal (BET) family of bromodomains. This study is designed to characterize the safety, tolerability, pharmacokinetics and anti-tumor activity of RO6870810 in participants with histologically confirmed solid tumors with progressive disease (PD) which is refractory or intolerant to standard/approved therapies. In Part A, RO6870810 will be administered by subcutaneous (SC) injection daily for either 21 consecutive days in a 28-day cycle or for 14 consecutive days in a 21-day treatment cycle in participants with advanced solid tumor malignancies to determine the maximum tolerated dose (MTD) and dose-limiting toxicities (DLT). In Part B, RO6870810 will be administered at a dose up to the MTD to further characterize the safety profile and biological effect in a subset of participants with advanced solid tumor malignancies. It is anticipated that a total of 84 participants will be enrolled in to this study (54 in Part A and 30 in Part B). In addition, it is expected that up to 20 participants with histologically confirmed nuclear protein in testis (NUT)-midline carcinoma (NMC) with progressive disease requiring therapy will be enrolled in the sub-study of Parts A and B. In addition, up to 20 participants with diffuse large B-cell lymphoma (DLBCL) may be enrolled at selected study sites.
