Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
Key

* Dose Escalation Cohorts: Histologically or cytologically confirmed advanced malignant solid tumor that is refractory to or intolerant of all standard therapy or for which no standard therapy is available.
* Dose Expansion and 1000 mg twice a day (BID) Dose Escalation Cohorts: Individuals must have available sufficient and adequate formalin fixed tumor sample preferably from a biopsy of a tumor lesion obtained either at the time of or after the diagnosis of advanced disease has been made and from a site not previously irradiated. Alternatively, individuals must agree to have a biopsy taken prior to entering the study to provide adequate tissue. For the 1000 mg BID dose escalation cohort, individuals with melanoma, Merkel cell, microsatellite instability-high (MSI-H) cancers, and classical Hodgkin lymphoma (cHL) are not required to have archival or fresh biopsy tissue.
* Dose Escalation Biopsy Substudy and 1000 mg BID Dose Escalation Cohorts: Documented ligand 1 of programmed cell death protein 1 (PD-L1) expression in the tumor (tumor proportion score (TPS) = 10% or combined positive score (CPS) = 10). In the 1000 mg BID Cohort, PD-L1 expression will not be required for Merkel cell, melanoma, MSI-H cancers, and cHL.
* Eastern Cooperative Oncology Group (ECOG) Performance Status of = 2.
* Adequate organ function.

Key exclusion criteria
* History or evidence of clinically significant disorder, condition, or disease that, in the opinion of the Investigator or Medical Monitor would pose a risk to individual safety or interfere with the study evaluations, procedures, or completion.
* Dose Escalation Cohorts: History of = Grade 3 Adverse Events (AEs) during prior treatment with an immune checkpoint inhibitor, or history of discontinuation of treatment with an immune checkpoint inhibitor due to AEs.
* Dose Escalation 1000 mg BID and Dose Expansion Cohort: Prior treatment with an immune checkpoint inhibitor (anti-PD-1, anti-PD-L1, or anti- ligand 2 of programmed cell death protein 1 (PD-L2) antibodies).
* History of autoimmune disease (for example, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, vascular thrombosis associated with antiphospholipid syndrome, Wegener's granulomatosis, Sjögren's syndrome, Bell's palsy, Guillain-Barré syndrome, multiple sclerosis, autoimmune thyroid disease, vasculitis, or glomerulonephritis).
