PHASE1/PHASE2

A Study of Catequentinib Hydrochloride (AL3818) in Endometrial, LGSOC, STS or GBM Cancers

Sponsor: Advenchen Pharmaceuticals, LLC.

View on ClinicalTrials.gov

Summary

This phase 1b/2a study evaluates the investigational oral drug catequentinib hydrochloride (AL3818), given alone or with AL58805, temozolomide, or lomustine (CCNU), in adults with advanced or metastatic solid tumors. The phase 1b part will identify doses that can be given safely based on side effects during the first treatment cycle. The phase 2a part will estimate whether the treatments shrink non-brain tumors or keep glioblastoma from worsening for at least 6 months. The study is open label, which means participants and study investigators will know which treatment is given. Tumor response will be assessed with RECIST version 1.1. The study will also evaluate how the investigational drugs move through the body, the duration of tumor response, progression-free survival, overall survival, and treatment safety.

Official title: Phase 1b/2a Clinical Study of Catequentinib Hydrochloride (AL3818) Monotherapy or Combining Therapy With Other Anti-tumor Agents in Advanced, Metastatic Endometrial, Low Grade Serous Ovarian Cancer (LGSOC), STS or GBM Cancers

Interventions

DRUG

AL58805

AL58805 is a novel chemical-structure antitumor drug with independent intellectual property rights. It functions as a novel dual-target PI3K/mTOR kinase inhibitor, exhibiting effects such as inhibiting tumor cell growth and proliferation, suppressing tumor nutrient metabolism, and exerting anti-angiogenic activity. By simultaneously inhibiting both PI3K and mTOR, it completely blocks the entire PI3K/AKT/mTOR signaling pathway at relatively low safe doses, thereby enhancing antitumor efficacy.

DRUG

AL3818

AL3818 is a novel small molecule dual receptor tyrosine kinase inhibitor, which shows highly selective inhibition of fibroblast growth factor receptor (FGFr) and vascular endothelial growth factor receptor (VEGFR). Preclinical studies of this agent in mouse models, including various cancer xenografts, have demonstrated that treatment of tumor-bearing mice with AL3818 induces tumor reductions.

DRUG

Temozolomide (TMZ)

Temozolomide is an alkylating agent, which metabolizes to generate active substance methyl triazene imidazole formamide (MTIC), which interferes with the replication and repair of tumor cell DNA and induces apoptosis of cancer cells.

DRUG

CCNU

CCNU is an alkylating agent that works by damaging cancer cell DNA, ultimately leading to cell death. It is lipid-soluble, allowing it to cross the blood-brain barrier, which is crucial for treating brain tumors.
