Clinical Trials associated with CBP-1018

NCT04928612

/ RecruitingPhase 1

An Open-Label, Non-randomized, Multi-center Phase I Study Evaluating the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of Bi-Ligand-Drug Conjugate CBP-1018 in Patients With Advanced Solid Tumors

This is an open-label, non-randomized, multi-center, phase I study of bi-ligand-drug conjugate CBP-1018 in patients with advanced solid tumors. This study will be conducted in 2 parts: Part A (Dose Escalation) and Part B (Dose Expansion). Both parts include screening period, treatment period, end of treatment (EOT)/withdrawal, safety follow-up (SFU) and long-term-follow-up (LTFU). CBP-1018 will be administrated on eligible subjects until disease progression, unacceptable toxicity, withdrawal of consent or Sponsor's decision to stop the study, etc.

LC-MS/MS method for dual-ligand peptide-drug CBP-1018 and its deconjugated payload MMAE including sample stabilization strategy for its MC-Val-Cit-PABC linker

Article

Recently, peptide-drug conjugate (PDC) has become the most promising conjugated drug for tumor therapy after antibody-drug conjugate due to stronger tumor penetration capacity and lower immunogenicity. CBP-1018 was a PDC with dual-ligand conjugated to MMAE via a cleavable linker (MC-Val-Cit-PABC) that can be lysed by cathepsins B. In this study, two specific LC-MS/MS methods were developed and validated for the determination of CBP-1018 and its metabolite MMAE in human plasma. To prevent the cleavable MC-Val-Cit-PABC linker from degradation, a protease inhibitor (cOmplete solution) was added to the pre-cooled vacuum tubes and the separated plasma samples. The assays involved the pretreatment of CBP-1018 by protein precipitation with H₂O-ACN (1:9, v/v) and the extraction of MMAE by liquid-liquid extraction with ethyl acetate under alkaline condition to eliminate the interference of CBP-1018 on MMAE. The two analytes showed good linearities over the calibration ranges (R² ≥ 9980). Both accuracy and precision met the acceptance criteria. The validated methods were successfully applied to the phase I dose-escalation study of CBP-1018 injection in Chinese patients with solid tumors to evaluate the pharmacokinetic properties of CBP-1018 and MMAE. The results showed that CBP-1018 was eliminated immediately after injection and MMAE reached the maximum exposure at approximately 2 h after infusion. The maximum concentration of MMAE did not exceed 20.0 ng/mL, suggesting that the off-target toxicity of CBP-1018 injection was controllable.
