Overview
Brief Summary
This is a first-in-human, Phase 1, open-label, multicenter, dose-escalation study designed to evaluate the safety, tolerability, and pharmacokinetics of MOXR0916 administered intravenously in participants with locally advanced or metastatic solid tumors that have progressed after all available standard therapy or for which standard therapy has proven to be ineffective or intolerable, or is considered inappropriate. This study will consist of a screening period, an initial treatment period, a re-treatment period (for participants who discontinue MOXR0916 after demonstration of prolonged clinical benefit), and a post-treatment follow-up period. Participants will be enrolled in two stages: a dose-escalation stage and an expansion stage. The planned duration of the study is approximately 3 years.

Eligibility Criteria
Inclusion Criteria

Exclusion Criteria
- •Any anti-cancer therapy, including chemotherapy, hormonal therapy, or radiotherapy, within 3 weeks prior to initiation of study treatment (hormonal therapy with gonadotropin-releasing hormone agonists or antagonists for prostate cancer and palliative radiotherapy greater than (\>) 2 weeks prior to Cycle 1, Day 1 are allowed)
- •Eligibility based on prior treatment with immunomodulatory agents depends on the mechanistic class of the drug and the cohort for which the participant is being considered

Arms & Interventions
MOXR0916: Dose Escalation Stage
Participants in different cohorts (according to MOXR0916 dose received) will receive escalating doses of MOXR0916 to determine the MTD or maximum administered dose (MAD) for 21 to 42 days.
Intervention: MOXR0916
MOXR0916: Expansion Stage
Participants in different cohorts (according to different cancer types, prior therapy and mandatory procedures on study) will receive MOXR0916 at the highest dose level that has already been deemed to be tolerable in the dose escalation stage until disease progression, loss of clinical benefit or unacceptable toxicity, whichever occurred first (approximately up to 3 years).
Intervention: MOXR0916
