- Has prostate cancer progression on the most recent treatment, as determined by the investigator, by means of one of the following: a) Prostate-Specific Antigen (PSA) progression using local laboratory values as defined by a minimum of 2 rising PSA levels with an interval of ≥1 week between each assessment where the PSA value at screening should be ≥2 ng/mL; b) Radiographic disease progression in soft tissue based on RECIST 1.1 criteria with or without PSA progression; c) Radiographic disease progression in bone defined as the appearance of 2 or more new bone lesions on bone scan with or without PSA progression.
- Has progressed on at least one second generation anti-androgen therapy (e.g., enzalutamide, abiraterone).

- Has been previously treated with standard therapies, which must include fluoropyrimidine, oxaliplatin, and irinotecan.
- Has a known additional malignancy that is progressing or has required active treatment within the past 2 years. Note: Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or carcinoma in situ (e.g. breast carcinoma, cervical cancer in situ) that have undergone potentially curative therapy are not excluded.
- Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Participants with previously treated brain metastases may participate provided they are radiologically stable, i.e., without evidence of progression for at least 4 weeks by repeat imaging, clinically stable and without requirement of steroid treatment for at least 14 days prior to first dose of study treatment.

- Primary Outcome Measures
Name Time Method Objective Response Rate (ORR) Based on Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) Up to approximately 2 years ORR is defined as the percentage of participants 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) per RECIST 1.1. ORR was estimated using an exact method based on the binomial distribution, and the 95% confidence interval was estimated by the method of Clopper-Pearson.
Number of Participants With Dose-limiting Toxicities (DLTs) During Treatment Cycle 1 Up to 21 days The following toxicities are considered a DLT, assessed as related to study treatment: Grade 4 non-hematologic toxicity, Grade 4 anemia, Grade 3 anemia lasting \>7 days or requiring transfusion, Grade 4 hematologic toxicity lasting ≥7 days, except thrombocytopenia, a) Grade 4 thrombocytopenia of any duration, b) Grade 3 thrombocytopenia associated with bleeding, Grade 3 non-hematologic toxicity lasting \>3 days, any Grade 3 or Grade 4 non-hematologic laboratory value if: medical intervention is required or the abnormality leads to hospitalization or persists for \>72 hours, Liver test abnormalities: Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) \>3X Upper Limit of Normal (ULN) with total bilirubin (TBL) \>2X ULN with no elevation in alkaline phosphatase (AP \<2X ULN), Grade 3 or Grade 4 febrile neutropenia, inability to administer ≥75% of the planned navarixin dose due to drug-related tolerability, delay in Cycle 2 start by \>2 weeks due to toxicity
Number of Participants Who Experience at Least One Adverse Event (AE) Up to approximately 27 months An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study treatment.
Number of Participants Who Discontinue Study Treatment Due to an AE Up to approximately 2 years An AE is any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study treatment.
- Secondary Outcome Measures
Name Time Method Progression-free Survival (PFS) Per RECIST 1.1 Up to approximately 2 years PFS is defined as the time from the first dose of study treatment to the first confirmed documented disease progression, or death due to any cause, whichever occurs first. Per RECIST 1.1, progressive disease is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. Note: The appearance of one or more new lesions is also considered progression. Median PFS per RECIST 1.1 was assessed by the investigator from product-limit (Kaplan-Meier) method for censored data in participants with microsatellite stable colorectal cancer (CRC); with castration-resistant prostate cancer (CRPC), and with programmed cell death ligand 1 (PD-\[L\]1) refractory non-small cell lung cancer (NSCLC).
Objective Response Rate (ORR) Per Modified RECIST 1.1 for Immune-based Therapeutics (iRECIST) Up to approximately 2 years An objective response is defined as an immune-based Complete Response (iCR: Disappearance of all target lesions) or immune-based Partial Response (iPR: At least a 30% decrease in the sum of diameters of target lesions). ORR will be assessed by the investigator based on iRECIST following administration of navarixin in combination with pembrolizumab. The percentage of participants with progressive disease per RECIST 1.1 who experience an iCR or iPR are presented.
PFS Per iRECIST Up to approximately 2 years PFS is defined as the time from the first dose of study treatment to the first documented disease progression or death due to any cause, whichever occurs first. Per iRECIST, progressive disease (PD) is defined as ≥20% increase in the sum of diameters of target lesions. Disease progression is to be confirmed by a consecutive assessment at least 4-8 weeks after first documentation and will be assessed by the investigator. Median PFS per iRECIST was assessed by the investigator from product-limit (Kaplan-Meier) method for censored data in participants with microsatellite stable colorectal cancer (CRC); with castration-resistant prostate cancer (CRPC), and with programmed cell death ligand 1 (PD-\[L\]1) refractory non-small cell lung cancer (NSCLC).
Overall Survival (OS) Up to approximately 2 years OS is defined as the time from the first dose of study treatment to death due to any cause. Median OS was assessed from product-limit (Kaplan-Meier) method for censored data in participants with microsatellite stable colorectal cancer (CRC); with castration-resistant prostate cancer (CRPC), and with programmed cell death ligand 1 (PD-\[L\]1) refractory non-small cell lung cancer (NSCLC).
Absolute Neutrophil Counts (ANC) Day 3: Predose Peripheral blood neutrophil counts were performed at Cycle 1 Day 3: Predose, to determine the concentration of ANC.
