Keywords

Phase I, Bispecific antibody, OX40, PD-L1, EMB-09, Immuno-oncology, dose escalation, cohort expansion, advanced solid tumor

Brief summary

This study is to evaluate the safety and tolerability of EMB-09 and to determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D). Pharmacokinetics (PK), immunogenicity, and the anti-multiple myeloma activity of EMB-09 will also be assessed.

Detailed description

This is a phase I, multi-center, open label, multiple dose, first in human study, designed to assess safety and tolerability, and to identify the maximum tolerated dose (MTD) and/or recommended Phase 2 dose for EMB-09 in patient with advanced or metastatic solid tumors. Pharmacokinetics,pharmacodynamics, immunogenicity and response will also be assessed.

Inclusion criteria

* Willing and able to provide signed and dated informed consent prior to any study-related procedures and willing and able to comply with all study procedures. * Phase I subjects: 1. Patients with histologically or cytologically confirmed locally advanced/metastatic solid tumors including but not limited to melanoma, non-small cell lung cancer (NSCLC), triple negative breast cancer (TNBC), head and neck squamous cell carcinoma (HNSCC), nasopharyngeal cancer (NPC), hepatocellular carcinoma (HCC), gastric cancer (GC), endometrium cancer (EC), ovarian cancer (OC), renal cell carcinoma (RCC) and small cell lung cancer (SCLC), colorectal cancer (CRC). 2. Patients who have failed (progressed on, or are intolerant of) standard therapies or no available standard treatment 3. Measurable or evaluable disease per RECIST v1.1. * Patients must provide archival tumor, or a fresh tumor biopsy will be required if archival tumor sample is not available. Archival tumor sample must be taken \<2 years prior to screening, otherwise a fresh tumor biopsy at screening is required. * ECOG performance status 0 or 1; life expectancy \> 3 months. * Adequate organ function to participate in the trial. * Recovery from adverse events (AEs) related to prior anticancer therapy. * Highly effective contraception

Exclusion criteria

Design outcomes

Primary

MeasureTime frameDescription
Incidence and severity of adverse events as assessed by CTCAE V5.0Screening up to 30 days after the last dose.Incidence and severity of AE.
Incidence of serious adverse events. (SAE)Screening up to 30 days after the last dose, or beyond 30 days if SAE is confirmed to be treatment related.Incidence of SAE.
Incidence of dose interruptions.Screening up to 30 days after the las dose.Incidence of dose interruptions of EMB-09 during treatment as a measure of tolerability.
Dose intensity.Screening up to 30 days after the last dose.Actual amount of drug taken by patients divided by the planned amount.
The incidence of DLTs during the first cycle of treatment.First infusion to the end of cycle 1. (each cycle is 28 days)The dose limiting toxicities are based on drug related adverse events and are specifically defined in study protocol.
