Trial Review
COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this

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:

care chemotherapy per local standards.
