Brief Summary
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.

Outcome Measures
Primary Outcomes (3)
Dose Escalation and Expansion Phases: Number of Participants Reporting one or More Treatment-emergent Adverse Events (TEAEs) and Based on TEAEs Severity
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)
Up to approximately 24 months
Dose Escalation and Expansion Phases: Number of Participants with Dose-Limiting Toxicities (DLTs)
DLT will be defined as the occurrence of any of the following events in the first 28 days of treatment in the dose escalation cohorts in Part 1 of the study or in the first 28 days of treatment for the first 6 patients at any dose in Part 1b (DLT observation periods). 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.
Up to approximately 24 months
Dose Escalation and Expansion Phases: Number of Participants Reporting One or More Treatment Emergent Serious Adverse Event (SAEs)
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.
Up to approximately 24 months

Study Arms (3)
Part 1a: Monotherapy Dose Escalation
EXPERIMENTALONM-501 will be administered as intratumoral injections once per week for three weeks, followed by three weeks without ONM-501 administration. Each dosing cycle will be 21 days.
Part 1b: ONM-501 in Combination with cemiplimab
EXPERIMENTALONM-501 will be administered as intratumoral injections once per week for three weeks followed by three weeks without ONM-501 administration. Each dosing cycle will be 21 days. The combination agent will be administered according to standard protocol, once every three weeks.
Part 2: RDE ONM-501 in Combination with cemiplimab in indication-specific expansion cohorts
EXPERIMENTALOnce the recommended doses for expansion (RDEs) are determined for ONM-501 + ICI combination or ONM-501 monotherapy, the expansion phase of the study will be initiated. The expansion phase will enroll patients in one to three indication-specific expansion cohorts.
Interventions
Intratumoral injection
Intravenous administration of 350 mg

- Participants with solid tumors or lymphomas, confirmed by available histopathology records or current biopsy, that are advanced, nonresectable, or recurrent and progressing since last antitumor therapy, and for which no alternative standard therapy exists.
- Participants must have a minimum of one injectable and measurable lesion.
- Participants with prior Hepatitis B or C are eligible if they have adequate liver function
- Participants with human immunodeficiency virus (HIV) are eligible if on established HAART for a minimum of 4 weeks prior to enrollment, have an HIV viral load \<400 copies/mL, and have CD4+ T-cell (CD4+) counts ≥ 350 cells/uL
- Adequate bone marrow function:
- Adequate liver function
You may not qualify if:

- Has uncontrolled or poorly controlled hypertension as defined by a sustained BP \> 9. Has received prior investigational therapy within 5 half-lives of the agent or 4 weeks before the first administration of study drug, whichever is shorter.
- Has had any major cardiovascular event within 6 months prior to study drug 10. Has known hypersensitivity to any component in the formulation of ONM-501
- Has an active infection requiring systemic treatment
- Is participating in another therapeutic clinical trial
- Has known hypersensitivity to any component in the formulation of cemiplimab
- Has any active or recent history of a known or suspected autoimmune disease or recent history of a syndrome that required systemic corticosteroids (\>10 mg daily prednisone equivalent)
- Has a condition requiring systemic treatment with corticosteroids
