简要总结
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetic, pharmacodynamic, preliminary anti-tumor activity, and to determine the recommended Phase II dose (RP2D) of the ALE.P03 monotherapy in adult patients with selected squamous solid tumors.
详细描述
This Study has a Phase I ALE.P03 monotherapy dose escalation and recommended dose for expansion (RDE) study and a Phase II study of ALE.P03 as monotherapy at RP2D in adult patients with selected advanced or metastatic Claudin-1 positive (CLDN1+) cancers.

研究组 & 干预措施
Phase I Dose Escalation- ALE.P03
Patients will receive ALE.P03 as monotherapy via intravenous infusion. The ALE.P03 will be given at an escalated dose until Maximum tolerated dose (MTD) and/or a safe recommended dose for expansion (RDE) is determined in Phase I dose escalation part of the study.
干预措施: ALE.P03 (Drug)
Phase II- ALE.P03
Patients will receive ALE.P03 as monotherapy via intravenous infusion at the RP2D, or according to the dosing schedule after the dose expansion phase.
干预措施: ALE.P03 (Drug)
Phase I Dose Expansion- ALE.P03
Patients will receive ALE.P03 as monotherapy via intravenous infusion. The safe recommended doses of ALE.P03 will be given in Phase I dose expansion part of the study to identify recommended Phase II dose (RP2D) for Phase II.
干预措施: ALE.P03 (Drug)
结局指标
主要结局
Number of Patients with Dose Limiting Toxicities (DLTs) (Phase I)
时间窗: Up to 28 days
DLTs as defined in the protocol will be assessed to evaluate safety and tolerability of ALE.P03 (Phase I Dose Escalation), and to establish RP2D for ALE.P03 (Phase I RDE).
Number of Patients with Adverse Events (Phase I)
时间窗: From Day 1 up to Safety follow-up (30 ± 5 days post last dose [Up to 4 years])
Adverse events will be assessed to evaluate safety and tolerability of ALE.P03 (Phase I Dose Escalation), and to establish RP2D for ALE.P03 (Phase I RDE).
Overall Response Rate (ORR) (Phase I)
时间窗: From ALE.P03 treatment initiation until at or prior to initiation of the use of new anti-cancer therapy (Up to 4 years)
The ORR is the proportion of patients with a best overall response (BOR) of complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST 1.1.) This is assessed to establish RP2D for ALE.P03 (Phase I RDE)
Duration of Response (DoR) (Phase I)
时间窗: From ALE.P03 treatment initiation until disease progression or study completion (Up to 4 years)
The DoR is defined for patients achieving a CR or PR as per Investigator review according to RECIST 1.1 to disease progression before new anti-cancer therapy or death of any cause, whichever occurs earlier. This is assessed to establish RP2D for ALE.P03 (Phase I RDE).
Overall Response Rate (ORR) (Phase II)
时间窗: From ALE.P03 treatment initiation until at or prior to initiation of the use of new anti-cancer therapy (Up to 4 years)
The ORR is assessed to assess anti-tumor activity of ALE.P03 (Phase II).
Duration of Response (DoR) (Phase II)
时间窗: From ALE.P03 treatment initiation until disease progression or study completion (Up to 4 years)
The DoR is defined for patients achieving a confirmed CR or PR as the time from the initial response of CR or PR to disease progression before new anti-cancer therapy or death of any cause, whichever occurs earlier. This is assessed to assess anti-tumor activity of ALE.P03 (Phase II).
