Brief Summary
The main aim of this study is to check if people with advanced solid tumors have side effects from dazostinag, and to check how much dazostinag they can receive without getting significant side effects from it when given alone and in combination with pembrolizumab. The study will be conducted in two phases including a dose escalation phase and a dose expansion phase. In the dose escalation phase, escalating doses of dazostinag are being tested alone and in combination with pembrolizumab to treat participants who have advanced or metastatic solid tumors. In the dose expansion phase, dazostinag will be studied with pembrolizumab with or without chemotherapy in participants with untreated metastatic or recurrent, unresectable squamous cell carcinoma of head and neck (SCCHN) and in combination with pembrolizumab in third-line or later recurrent locally advanced or metastatic microsatellite instability-high/mismatch repair deficient (MSI-H/dMMR) and third-line recurrent locally advanced or metastatic microsatellite stable/mismatch repair proficient (MSS/pMMR) colorectal cancer (CRC).

Outcome Measures
Primary Outcomes (4)
Number of Participants Reporting one or More Treatment-emergent Adverse Events (TEAEs) and Based on TEAEs Severity
A severity grade is defined by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 5.0. 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 68 months
Number of Participants with Dose-Limiting Toxicities (DLTs)
A DLT will be defined as any of the TEAEs, but not limited to, those that occur during Cycle 1 and are considered by the investigator to be at least possibly related to dazostinag as a SA or in combination with pembrolizumab. TEAEs meeting DLT definitions occurring in Cycle 2 or later will be considered in the determination of the RDE of dazostinag, both in the dazostinag SA and the combination with pembrolizumab arms. Toxicity will be evaluated according to NCI CTCAE version 5.0.

Eligibility Criteria
You may qualify if:
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.
- Dazostinag SA (dose escalation Part 1A):
- o With histologically confirmed (cytological diagnosis is acceptable) advanced or metastatic solid tumors that have no standard therapeutic options or are intolerant to these therapies.
- Dazostinag in combination with pembrolizumab (dose escalation Parts 1B and Japan safety lead-in):
- With histologically confirmed (cytological diagnosis is acceptable) advanced or metastatic solid tumors that have no standard therapeutic options or are intolerant to them, including:
- Tumors that have relapsed or are refractory to anti-programmed cell death ligand protein 1 (anti PD-(L)-1) therapy.
- Tumors that are naive to anti-PD-(L)-1 therapy.
- For expansion phase only:
- SCCHN (Part 2):
- Participants with histologically confirmed (cytological diagnosis is acceptable) metastatic or recurrent, unresectable SCCHN that is considered incurable by local therapies. Participants should not have had prior systemic therapy administered in the recurrent or metastatic setting. Systemic therapy which was completed more than 6 months before signing consent if given as part of multimodal treatment of locally advanced disease is allowed.
- Anatomic subsites to be included are oral cavity, oropharynx, hypopharynx, larynx, nasal cavity, and paranasal sinuses (maxillary, ethmoid, sphenoid, and frontal). The exception to this is nasopharyngeal cancer and salivary gland tumors, which will not be included.
- Participants with oropharyngeal cancer or tumors arising in the paranasal sinuses (maxillary, ethmoid, sphenoid, and frontal) must agree to provide archival tissue for human papilloma virus (HPV) testing or if known, HPV testing results (using CINtec® p16 Histology assay is preferred but not required) and a 70% cutoff point must be provided. Alternatively, archival tissue or a fresh excisional or core needle biopsy (≥ 2 cores) is required for the determination of HPV status. If HPV status was previously tested using this method (CINtec® p16 Histology assay is preferred but not required), no additional testing is required. Archival tissue can be obtained up to 90 days prior to screening. Samples that are older than 90 days at screening may be used after consultation with the sponsor.
- For Part 2A, tumors must have a PD-L1 CPS ≥ 1. Participants must agree to provide fresh tumor biopsy for analysis from a core or excisional biopsy (fine needle aspirate is not sufficient) at screening for PD-L1 CPS assessment by a central laboratory. This specimen may be the diagnostic sample for participants with a new diagnosis of metastatic SCCHN. Participants for whom newly obtained samples cannot be obtained (eg, inaccessible or participant safety concern) may submit an archived specimen only upon agreement from the Sponsor. Archival tissue can be obtained up to 90 days prior to screening provided there was no other treatment from the time of biopsy until the start of study treatment. For Part 2B, any CPS is eligible but fresh or archival tissue is required for confirmation of CPS status. Collection of the tissue samples for PD-L1 assessments for Part 2B can be discontinued by the sponsor if sufficient data has been collected or dazostinag activity does not justify further collection.
- For Part 2B, participants must be eligible to receive treatment with either cisplatin or carboplatin in combination with 5-fluorouracil (5-FU) per the treating physician.
