Interventional
Description of intervention(s) / exposure
Treatment: Drugs - APL-501

Experimental: Single-Arm - APL-501


Treatment: Drugs: APL-501
Subjects will be assigned to a dose level in the order of study entry. Treatment includes a minimum of four 28-day cycles at three planned dose levels (1, 3, and 10 mg/kg). In the Dose Escalation Segment, each treatment cycle is comprised of 2 doses of study drug administered on Days 1 and 15 of a 28-day cycle. In the Cohort Extension, the treatment cycle will consist of 2 doses of study drug administered on Days 1 and 15 of a 28-day cycle.

In Dose and Disease Expansion, the treatment cycle will consist of 2 doses of study drug (non-weight based dosing of 400 mg) administered on Days 1 and 15 of a 28-day cycle.

Eligibility
Key inclusion criteria
Major

• Able to understand and comply with study procedures, understand the risks involved, and provide written informed consent.

Dose Escalation:

* Histologically and / or cytological confirmed solid tumors: colorectal, endometrial, gastric including, gastroesophageal junction adenocarcinoma (GC), head and neck (esophageal, hepatocellular (HCC), non-small cell lung cancer, mesothelioma, ovarian, and renal cell carcinoma (RCC), either refractory or relapsed to standard therapy or for which no effective standard therapy is available.
* No restriction to number of prior therapies for Dose Escalation Segment except for gastric and renal cell carcinoma.

Cohort Extension:

* Histologically and/or cytological confirmed solid tumors with an approved labelled indication for PD-1 inhibitors.
* Tumor biopsy at study entry and during therapy. Tumor sites used to satisfy this criterion must not have received any prior radiation therapy. Sites for biopsy must be distinct from target lesions used for efficacy assessment.
* Measurable disease according to RECIST v1.1.

Dose and Disease Expansion:

* MSI-H or dMMR per local laboratory and failed at least one prior line of standard of care chemotherapy per local standards.
* Carcinoma of Unknown Primary

Key exclusion criteria
* History of severe hypersensitivity to mAbs, excipients of the drug product or other components
* Prior malignancy active within the previous 2 years except for locally curable cancers that have been cured, such as basal or squamous cell skin cancer, superficial bladder cancer or carcinoma in situ of the cervix or breast
* Any active autoimmune disease or a documented history of autoimmune disease, or history of syndrome that required systemic steroids or immunosuppressive medications, except for subjects with vitiligo or resolved childhood asthma/atopy
* Prior therapy with an anti-PD-1, anti-PD-L1, anti-PDL-2, or anti-CTLA-4 antibody (or any other antibody targeting T cell co-stimulation pathways) (except NSCLC)
* Known significant mental illness or other conditions such as active alcohol or other substance abuse that, in the opinion of the Investigator, predisposes the subject to high risk of noncompliance with the protocol treatment or assessments.
