研究概览
简要总结
A phase 1, multicenter, open label, non-randomized dose escalation and dose expansion study to examine the maximum tolerated dose, (MTD), minimum effective dose (MED) and/or recommended dose for expansion (RDE) of intratumoral ONM-501 as monotherapy and in combination with a PD-1 checkpoint inhibitor in patients with advanced solid tumors and lymphomas.
详细描述
This Phase 1, multi-center trial will consist of three parts: monotherapy dose escalation; combination therapy dose finding; and combination therapy dose expansion exploring two doses in specific tumor indication(s). Each dosing cycle of ONM-501 will be 21 days. ONM 501 will be administered as intratumoral injections once per week for three weeks (on Days 1, 8, and 15), followed by three weeks without ONM-501 administration. The monotherapy dose escalation will utilize an accelerated titration method.
The combination agent will be administered according to standard protocol, once every three weeks. This phase will evaluate ONM-501 in combination with approved immune checkpoint inhibitor (ICI) cemiplimab. Enrollment in this phase will follow a "Rolling 6" or 6+0 methodology - up to 6 patients will be enrolled in a staggered format; dose escalation of ONM-501 will be permitted.
Once the recommended doses for expansion (RDEs) are determined for ONM-501 + ICI combination or ONM-501 monotherapy, the expansion phase of this study will be initiated. The expansion phase will enroll patients in one to three indication-specific expansion cohorts.

结局指标
主要结局
Dose Escalation and Expansion Phases: Number of Participants Reporting one or More Treatment-emergent Adverse Events (TEAEs) and Based on TEAEs Severity
时间窗: Up to approximately 24 months
AE incidence will be coded using Medical Dictionary for Regulatory Activities (MedDRA) terminology. AE severity will be graded according to NCI CTCAE version 5.0 or later. Grade 1 scales as Mild (asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated); Grade 2 scales as Moderate (minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental Activities of Daily Living \[ADL\]); Grade 3 scales as Severe (severe or medically significant but not immediately life threatening hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL); Grade 4 scales as Life-threatening consequences, urgent intervention indicated, and Grade 5 scales as Death related to Adverse Event (AE)

Any adverse event resulting in a dose hold or delay of ≥ 28 days will be considered a DLT. Toxicity will be evaluated according to NCI CTCAE version 5.0.
Dose Escalation and Expansion Phases: Number of Participants Reporting One or More Treatment Emergent Serious Adverse Event (SAEs)
