About
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 preliminary Recommended Phase 2 Dose (RP2D) determined in Part 1 PLUS pembrolizumab via IV infusion for up 35 cycles (up approximately 2 years).
Full description
Participants will receive either ulevostinag monotherapy or ulevostinag in combination with pembrolizumab for up to 35 cycles (approximately 2 years). Participants will undergo at least a 24-hour inpatient observation period following the first dose administration of ulevostinag on Cycle 1 Day 1 in Part 1. For Part 2, the length of the observation period following administration of the first dose of ulevostinag on Cycle 1 Day 1 is at least 8 hours.

Male participants must agree to refrain from donating sperm PLUS either be abstinent from heterosexual intercourse (on a long-term and persistent basis) OR agree to use a male condom plus partner use of an additional contraceptive method when having penile-vaginal intercourse contraception, unless confirmed to be azoospermic (vasectomized) during the intervention period and for at least 130 days after the last dose of study intervention.

All Part 1 Arms:
-Has ≥1 distant, discrete non-injected lesion which is amenable to biopsy. This lesion must be measurable as defined by the response criteria used to assess the participant (RECIST 1.1 for solid tumors or revised International Working Group [IWG] criteria for lymphomas).
Part 1 Arm 1: Ulevostinag (Cut/Subcut Lesions) and Part 1 Arm 2: Ulevostinag+Pembro (Cut/Subcut Lesions):
- Has a histologically- or cytologically-confirmed advanced/metastatic solid tumor or lymphoma by pathology report and who has received, or been intolerant to, all treatment known to confer clinical benefit. Solid tumors and lymphomas of any type are eligible for enrollment.
- Has stage III or stage IV disease that is not surgically resectable. Stage IIB (T3N0M0B0-1) cutaneous T cell lymphoma (CTCL) participants are eligible.
Part 1 Arm 3: Ulevostinag+Pembro (Visceral Lesions):
- Has stage III or stage IV disease that is not surgically resectable.

All Part 2 Expansion Cohorts:
Part 2 Cohort A: HNSCC Anti-PD-1/PD-L1 Refractory:
- Has HNSCC of the oral cavity, oropharynx, hypopharynx, or larynx; anti-PD-1/PD-L1 refractory metastatic or recurrent. Participants may not have a primary tumor site of the nasopharynx (any histology).
