A Phase I Study of ROSE12 Alone and in Combination With Other Anti-tumor Agents in Patients With Solid Tumors

Summary

This is a Phase Ia/Ib open-label, dose-escalation study to evaluate the safety and pharmacokinetics of ROSE12 as a single agent and in combination with other anti-tumor agents in patients with locally advanced or metastatic solid tumors. The study will consist of three parts: a dose-escalation part, a biopsy part (the part to evaluate biomarkers), and an expansion part.

* Patients with histologic documentation of locally advanced, or metastatic solid tumor
* \[Dose-escalation Parts and Biopsy Parts\]Refractory or resistant to standard therapies or standard therapies are not available
* \[Dose-escalation Parts and Expansion Part\] Patients with confirmed availability of fresh tumor or representative tumor specimens
* \[Biopsy Parts\] Patients with accessible lesion(s)

Exclusion Criteria:

* Clinically significant cardiovascular or liver disease
* Treatment with investigational therapy and anti-cancer therapy within 28 days prior to initiation of study drug
* Any history of an immune-mediated Grade 4 adverse event attributed to prior cancer immunotherapy (other than asymptomatic elevation of serum amylase or lipase).
* All imAEs from prior cancer immunotherapy (other than endocrinopathy managed with replacement therapy, stable vitiligo or stable alopecia) that have not resolved completely to baseline.
* Adverse events from prior anti-cancer therapy that have not resolved to Grade ≤ 1 except for alopecia, vitiligo, or endocrinopathy managed with replacement therapy
* Primary central nervous system (CNS) malignancy, untreated CNS metastases requiring any anti-tumor treatment, or active CNS metastases
* Uncontrolled tumor-related pain
* Uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures
* Active or history of clinically significant autoimmune disease
* History of severe allergic, anaphylactic, or other hypersensitivity reactions to chimeric or humanized antibodies or fusion proteins.

\[Expansion Part\]

* Prior treatment with investigational product which has MoA of Treg depletion
* Malignancies other than disease under study within 5 years prior to Cycle 1 Day 1
