Primary | 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 | |
Primary | 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 | |
Primary | 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 | |
Secondary | Dose Escalation and Expansion Phases: Cmax | Cmax is defined as the Maximum Observed Plasma Concentration for ONM-501 | Dose Escalation and Expansion Phases: Cycle 1 Day 1 and Cycle 1 Day 8 (each cycle is 21 days): predose and at multiple timepoints (up to 24 hours). | |

Secondary | Expansion Phase Only: Objective Response Rate (ORR) | Objective response will be defined as a best response of CR or PR. The objective response rate (ORR) will be calculated as the proportion of patients in the Efficacy Analysis Set who achieve an objective response. ORR will be assessed based on Response Evaluation Criteria in Solid Tumor (RECIST) version 1.1.

Up to approximately 24 months | |
Secondary | Expansion Phase Only: Duration of Response (DOR) | DOR analyses will be conducted for those patients in the Efficacy Analysis Set who achieve an objective response and is defined as the time from first objective status assessment of CR or PR until documentation of objective disease progression or death from any cause. Patients who do not progress and do not die will be censored on the date of last adequate tumor assessment. If no further adequate post-treatment tumor assessments were obtained for a patient, DOR will be censored at the date of the objective response (i.e., zero duration). DOR will be assessed based on RECIST v1.1. | Up to approximately 24 months | |
Secondary | Expansion Phase Only: Progression-Free Survival (PFS) | PFS is defined as the time from administration of the first dose of ONM-501 until documentation of objective disease progression or death from any cause. Patients who do not progress and do not die will be censored on the date of last adequate tumor assessment. If no adequate post treatment tumor assessments were obtained for a patient, PFS will be censored at Day 1 (i.e., zero duration). The PFS analysis will be conducted using the Safety Analysis Set.
Assess the biological effects of IT ONM-501 demonstrated by changes in immune cells, immune cell markers, serum cytokines (such as TNF-?, IFN-?, IFN-ß, and others consistent with activation of the cGAS-STING pathway) and gene expression patterns |
Up to approximately 24 months | |
Secondary | Expansion Phase Only: Overall Survival (OS) | OS is defined as the time from the date of first dose administration to the date of death. | Up to approximately 24 months |
