Eligibility Criteria

Inclusion Criteria:

Written informed consent must be obtained prior to any procedures.
Male or female patient aged 18 years or older.

Pathologic diagnosis of solid tumor malignancy that is locally advanced or metastatic at time of Screening:

Part 1 Dose escalation camidanlumab tesirine as monotherapy:

Selected advanced solid tumors: colorectal, head and neck, NSCLC, gastric and esophageal cancers, pancreas, bladder, renal cell carcinoma, melanoma, TNBC, and ovarian/fallopian tube cancers

Part 1 Dose-escalation camidanlumab tesirine in combination with pembrolizumab:

Selected advanced solid tumors: colorectal cancer, gastric-esophageal cancer, ovarian /fallopian tube cancer, pancreatic cancer, non-small cell lung cancer, and melanoma.

Note: For colorectal cancer, gastric-esophageal cancer, ovarian/fallopian tube cancer, pancreatic cancers mismatch repair (MMR) / microsatellite stability (MSS) / microsatellite instability (MSI) status is mandatory. If MMR/MSS/MSI status is not available at signature of the informed consent, the test should be performed before Cycle 1 Day 1 (C1D1).

Part 2 Dose expansion camidanlumab tesirine in combination with pembrolizumab:

Group 1: One of the indications identified in Part 1, for which at least 1 response (PR or CR) was seen.
Group 2: Patients with advanced solid tumors and MSI-H/dMMR status, who have received a prior regimen containing PD-1/PD-L1 inhibitors, for which the best response was CR, PR, or SD ≥4 months, and then progressed while under treatment with the PD-1/PD-L1 inhibitor-based regimen.

Note: A maximum of 4 patients with the same indication will be allowed in this basket group.

Patients who are refractory to or intolerant of existing therapy(ies) known to provide clinical benefit for their condition.
Patients with advanced/metastatic cancer, with measurable disease as determined by RECIST v1.1 or immune-related Response Criteria (irRC)/ immune-related Response Evaluation Criteria In Solid Tumors (irRECIST)/ immune-related Response Evaluation Criteria In Solid Tumors (iRECIST)/ immune-modified Response Evaluation Criteria in Solid Tumors (imRECIST) as per Investigator discretion.

A) For camidanlumab tesirine as monotherapy: Patient must have a site of disease amenable to biopsy and be willing to undergo fresh biopsy procedures (minimum 3 passes each) prior to first dose, according to the treating institution's guidelines.

B) Patients included in the paired-biopsy cohort must in addition be willing to undergo fresh biopsy procedures (minimum 3 passes each) after receiving at least 1 dose of study drug.

C) For camidanlumab tesirine in combination with pembrolizumab: Patient must either have a site of disease amenable to biopsy and must provide fresh tumor biopsy prior to C1D1, or have sufficient available archival tumor tissue (biopsied after their last disease progression, and in the situation where the patient has received no additional anti-cancer therapy between their progression and C1D1). Patients must also be willing to undergo fresh biopsy procedures (minimum 3 passes each) after receiving at least 1 dose of study treatment, according to the treating institution's guidelines.

Previously treated asymptomatic CNS metastases are permitted provided that the last treatment (systemic anticancer therapy and/or local radiotherapy) was completed ≥4 weeks prior to Day 1 except usage of low dose of steroids on a taper (i.e., up to 10 mg prednisone or equivalent on Day 1 and consecutive days is permissible if being tapered down). Patients with discrete dural metastases are eligible.
Clinically significant third space fluid accumulation (i.e., ascites requiring drainage or pleural effusion that is either requiring drainage or associated with shortness of breath).

For cytotoxic agents that have major delayed toxicity, e.g., mitomycin C and nitrosoureas, 4 weeks is indicated as washout period. For patients receiving systemic anticancer immunotherapies (as opposed to intralesional) that lead to activation of Teffs and/or increase the Teff/Treg ratio, such as anti-PD-1 antibodies, 4 weeks are indicated as the washout period.
Use of any other experimental medication within 14 days prior to start of study drug (C1D1).

Active second primary malignancy other than non-melanoma skin cancers, non-metastatic prostate cancer, in situ cervical cancer, ductal or lobular carcinoma in situ of the breast, or other malignancy that the Sponsor's medical monitor and Investigator agree and document should not be exclusionary.
Any other significant medical illness, abnormality, or condition that would, in the Investigator's judgment, make the patient inappropriate for study participation or put the patient at risk.
For patients treated with camidanlumab tesirine in combination with pembrolizumab: patients intolerant to checkpoint-inhibitor or with a history of the following ≥ Grade 3 immune-related adverse events: hepatitis, renal, ocular, neurologic, cardiovascular, rheumatologic, and hematologic.
