Intervention/exposure
Study type

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.

Objective Response Rate (ORR) - The treatment effect of APL-501 will be assessed by RECIST v1.1 and by irRECIST to determine proportion of patients with complete response or partial response.
Timepoint [5] 0 0
Approximately 24 months
Secondary outcome [6] 0 0
Duration of Response (DOR) - The treatment effect of APL-501 will be assessed by RECIST v1.1 or by irRECIST to determine duration of response. Time from first documented complete response or partial response until subsequent documented disease progression or death.
Timepoint [6] 0 0
Approximately 24 months
Secondary outcome [7] 0 0
Time to Response (TTR) - The treatment effect of APL-501 will be assessed by RECIST v1.1 and by irRECIST to determine time to complete response and partial response.
Timepoint [7] 0 0
Approximately 24 months
Secondary outcome [8] 0 0
Disease Control Rate (DCR) - The treatment effect of APL-501 will be assessed by RECIST v1.1 and irRECIST to determine disease control rate. Proportion of patients with best overall response of complete response, partial response, or stable disease.
Timepoint [8] 0 0
Approximately 24 months
Secondary outcome [9] 0 0
Progression Free Survival - The effect of APL-501 will be assessed by RECIST v1.1 and per irRECIST to determine progression free survival as time from date of first dose to date of disease progression or death.

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.

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
