This trial is a Phase 1b/2a/3 trial designed to evaluate the safety and efficacy of adding
oral AL3818 (Anlotinib, INN: Catequentinib), a Dual Receptor Tyrosine Kinase Inhibitor, to
standard platinum-based chemotherapy concurrently in Subjects with Recurrent or Metastatic
Endometrial, Ovarian, Fallopian, Primary Peritoneal or Cervical Carcinoma.
This trial is a Phase 1b/2a/3 trial designed to evaluate the safety and efficacy of adding
oral AL3818(Anlotinib, INN: Catequentinib) to standard platinum-based chemotherapy
concurrently and continued as a maintenance therapy for up to 12 months, in subjects with
recurrent or metastatic endometrial, ovarian, fallopian, primary peritoneal, or cervical
carcinoma. 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.
Phase 1 & 2: This study is divided into two parts. The objective of Part 1 is the evaluation
of the safety and tolerability of adding oral AL3818 to standard carboplatin plus paclitaxel
chemotherapy for a cycle of 21 days to determine the recommended Phase II dose (RP2D). Phase
1 / Part 1 is now complete. Part 2-The objective of Part 2 is evaluation of preliminary
efficacy and the safety of adding oral AL3818 at the RP2D determined in Part 1 to carboplatin
and paclitaxel chemotherapy for 6 cycles. Continuous maintenance mono therapy with 14 days on
and 7 days off regimen at the RP2D will be conducted up to 12 months and is extendable beyond
until disease progression. Phase I is closed and Phase 2 is closed.
Phase 3: This study is currently a Phase III, multi-center, randomized trial with active
control designed to evaluate the efficacy and safety of AL3818 8 mg plus background treatment
(Active Arm) vs background treatment alone (Control Arm), where three background treatments,
weekly paclitaxel, pegylated liposomal doxorubicin (PLD), and topotecan are utilized. Oral
AL3818 8 mg may be given concurrently with background treatment or alone if the background
treatment must be discontinued due to its toxicity for up to 24 cycles of therapy, in
subjects with recurrent or metastatic platinum-resistant ovarian, fallopian tube, or primary
peritoneal cancer. Phase 3 is open.
