Brief Summary:

The purpose of this study is to identify a maximum tolerated dose (MTD) or maximum administered dose (MAD) of ulevostinag alone and of ulevostinag in combination with pembrolizumab in participants with advanced/metastatic solid tumors or lymphomas in Part 1, and to evaluate the safety and efficacy of ulevostinag via intratumoral (IT) injection in combination with pembrolizumab in selected solid tumors in Part 2.

Ulevostinag will be administered IT; pembrolizumab (pembro) will be administered via intravenous (IV) infusion. In Part 1, participants will be allocated to one of three treatment arms: ulevostinag monotherapy (cutaneous/subcutaneous [cut/subcut] lesions), ulevostinag +pembro (cut/subcut lesions), or ulevostinag +pembro (visceral lesions).

In Part 2, participants with head and neck squamous cell carcinoma (HNSCC) who are anti-programmed cell death-protein 1 or anti-programmed cell death-ligand 1 (anti-PD-1/PD-L1) refractory or with anti-PD-1/PD-L1 treatment (TrT)-naïve triple-negative breast cancer (TNBC) or with anti-PD-1/PD-L1 TrT-naïve solid tumors with liver metastases/lesions will receive ulevostinag via IT injection at the RP2D determined in Part 1 PLUS pembrolizumab via IV infusion for up 35 cycles (up approximately 2 years).

    DLTs will be assessed during the first cycle (21 days) & are defined as: Grade (Gr) 4 nonhematologic toxicity; Gr 4 hematologic toxicity lasting ≥7 days, except thrombocytopenia, Gr 4 thrombocytopenia, Gr 3 thrombocytopenia (if associated with clinically significant bleeding); nonhematologic adverse event (AE) ≥ Gr 3 (with exceptions); Gr 3 or 4 nonhematologic lab abnormality (if medical intervention is required, leads to hospitalization, or persists for >1 week); Gr 3 or 4 febrile neutropenia; drug-related toxicity that causes treatment discontinuation or dose delay >7 days between consecutive doses during Cycle 1; drug-related toxicity that causes a >2 week delay in Cycle 2 initiation; elevated aspartate aminotransferase or alanine aminotransferase lab value that is ≥3× upper limit of normal (ULN) & an elevated total bilirubin value ≥2× ULN & an alkaline phosphatase value <2× ULN, in which no alternative reasons can be found; ≥Gr 2 immune-mediated uveitis; or Gr 5 toxicity.

  2. Parts 1 and 2: Percentage of Participants Who Discontinue Study Drug Due to an Adverse Event (AE) [ Time Frame: Up to approximately 2 years ]
    AEs are defined as any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of study treatment or protocol-specified procedure, whether or not considered related to the study treatment or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that is temporally associated with the use of the study treatment, is also an AE. The percentage of participants who discontinue study treatment due to an AE will be presented.


Secondary Outcome Measures :
  1. Parts 1 and 2: Ulevostinag Area Under the Plasma Drug Concentration-Time Curve From Time Zero to 24 Hours (AUC0-24) [ Time Frame: Cycle 1 Day 1: Predose, at end of IT injection (up to 15 minutes) and 0.5, 1, 1.5, 4, 6, 12, and 24 hours postdose. Each cycle is 21 days. ]
    The AUC0-24 of ulevostinag when administered as monotherapy and as combination therapy with pembrolizumab will be determined.

  2. Parts 1 and 2: Ulevostinag Minimum Plasma Concentration (Cmin) [ Time Frame: Cycle 1 Day 1: Predose, at end of IT injection (up to 15 minutes) and 0.5, 1, 1.5, 4, 6, 12, and 24 hours postdose; Cycle 2 Day 1: Predose, at end of IT injection (up to 15 minutes) and 0.5, 1, 1.5, 4 and 6 hours postdose. Each cycle is 21 days. ]
    The observed Cmin of ulevostinag when administered as monotherapy and as combination therapy with pembrolizumab will be determined.

  3. Parts 1 and 2: Ulevostinag Maximum Plasma Concentration (Cmax) [ Time Frame: Cycle 1 Day 1: Predose, at end of IT injection (up to 15 minutes) and 0.5, 1, 1.5, 4, 6, 12, and 24 hours postdose; Cycle 2 Day 1: Predose, at end of IT injection (up to 15 minutes) and 0.5, 1, 1.5, 4 and 6 hours postdose. Each cycle is 21 days. ]
    The observed Cmax of ulevostinag when administered as monotherapy and as combination therapy with pembrolizumab will be determined.

  4. Parts 1 and 2: Pembrolizumab Minimum Plasma Concentration (Cmin) [ Time Frame: Predose on Day 1 of Cycles 1, 2, and 4, and every 4 cycles thereafter up to Cycle 35 (up to 2 years). Each cycle is 21 days. ]
    The Cmin of pembrolizumab when administered as combination therapy with ulevostinag will be determined.

  5. Part 2: Objective Response Rate (ORR) As Assessed by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) [ Time Frame: Up to approximately 2 years ]
    ORR is defined as the percentage of participants in the analysis population who have a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters) per RECIST 1.1. The ORR of ulevostinag at the preliminary RP2D in combination with pembrolizumab will be assessed by RECIST 1.1 modified to follow a maximum of 10 target lesions with a maximum of 5 target lesions per organ. ORR for the three Part 2 cohorts will be reported.
