Overview
Brief Summary
This is a Phase 1/1b, open-label, first-in-human (FIH) study designed to evaluate the safety, tolerability, pharmacokinetics (PK) and preliminary antineoplastic activity of APS03118 administered orally in participants with RET-altered solid tumors.
Detailed Description
After being informed about the study procedure and potential risks and benefits, all patients giving written informed consent will undergo a 4-week screening period to determine eligibility for study entry. The eligible participants will be enrolled using a rolling 6 dose escalation scheme to identify MTD and/or RP2D.

Eligibility Criteria
Inclusion Criteria
- •Male or female patients aged 18 years or older
- •Have histological or cytological confirmation of unresectable locally advanced or metastatic solid tumors harboring oncogenic RET mutations or fusions confirmed by NGS. Site may identify patients with a RET-mutated or RET-fusion solid tumor before the formal screening.
- •Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or
- •Resolution of all toxic effects of prior therapies to Grade 1 or below according to NCI CTCAE version 5.0 (except alopecia or Grade 2 neuropathy);
- •Patients with asymptomatic brain metastases if they have been previously treated, demonstrated no progression at least for 1 months before Screening, are asymptomatic and have had no requirement for steroids or enzyme inducing anticonvulsants in the last 14 days before Screening
- •Adequate organ function
Exclusion Criteria
- •Have a locally advanced solid tumor that is a candidate for curative surgery treatment through radical surgery and/or radiotherapy.
- •Have an active fungal, bacterial, and/or active untreated viral infection
- •The patient has a serious pre-existing medical condition(s)
- •Have received or will receive a COVID-19 vaccine within 1 month before the first dose of APS03118.
