AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with advanced or metastatic squamous cancer of the lung, head and neck, oesophagus or cervix, who can give tumour tissue for CLDN1 testing.
- Age
- 18 years or older
- Sex
- All sexes can join
- Disease stage
- Advanced, locally recurrent and inoperable, or metastatic squamous cell cancer of the lung, head and neck (nasopharyngeal included), oesophagus or cervix, with disease that can be measured by RECIST 1.1
- Earlier treatment
- Depends on the study part. Dose escalation: at least one standard systemic treatment that stopped working or was not tolerated. Monotherapy expansion and Phase II: no more than 2 such treatments. Combination therapy: no earlier systemic therapy for incurable recurrent or metastatic disease.
- Biomarker or test result
- Tumour tissue must be given for CLDN1 testing in a central laboratory.
Main reasons for not taking part
- Cancer that is mainly non-squamous, such as adenosquamous carcinoma or adenocarcinoma
- Rapidly progressing disease, such as tumour bleeding or uncontrolled tumour pain
- Uncontrolled diabetes
- Known active brain or spinal cord metastases or carcinomatous meningitis
- Medicines that change the QT interval or carry a known risk of Torsades de Pointes

- Original description
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.P02 as a monotherapy or in combination with pembrolizumab in adult patients with selected squamous solid tumors.Read full original descriptionShow less
A Phase I/II, Open-Label, Multicenter Study of ALE.P02 (Claudin-1 Targeted Antibody-Drug Conjugate) as a Monotherapy or in Combination With Pembrolizumab (Anti-PD-1 Antibody) in Adult Patients With Selected Advanced or Metastatic CLDN1+Squamous Solid Tumors
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.P02 as a monotherapy or in combination with pembrolizumab in adult patients with selected squamous solid tumors.
Inclusion: Have disease and treatment history as: histologically or cytologically confirmed advanced locally recurrent and inoperable or metastatic SqNSCLC, HNSCC (nasopharyngeal cancer included), ESCC or CSCC; Phase I Dose Escalation: Have received at least one systemic standard of care regimen and being refractory or intolerant to the treatment; Phase I Monotherapy RDE and Phase II: Have received no more than 2 lines of systemic standard of care regimen and being refractory or intolerant to the treatment; Phase I Combination Therapy RDE: Have received no previous systemic therapy in incurable recurrent or metastatic setting; Have provided tissue for CLDN1 analysis in a central laboratory; Have a performance status of 0 or 1 on the Eastern Cooperative Oncology Group Performance Scale; Demonstrate adequate bone marrow and organ function; Patients must have recovered from all toxicities led by prior treatment; Have measurable disease based on RECIST 1.1 as determined by the site.
Exclusion: Has received antineoplastic therapies prior to study intervention within specified time frame; Diagnosed with cancers of predominantly non-squamous histology (eg, adenosquamous carcinoma) or adenocarcinoma; Has rapidly progressing disease (eg, tumor bleeding, uncontrolled tumor pain); Patients with uncontrolled diabetes; Has clinically significant gastrointestinal bleeding and has an active infection requiring systemic treatment and has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the clinical study, interfere with the patient's participation for the full duration of the clinical study, or is not in the best interest of the patient to participate; Concomitant use of drugs that are known to prolong or shorten QT and/or have known risk of Torsades de Pointes; Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis.
