RECRUITING

A Study to Evaluate TROP2 ADC LCB84 Single Agent and in Combination With an Anti-PD-1 Ab in Advanced Solid Tumors

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This is a first-in-human, Phase 1/2 study to evaluate LCB84, a TROP2-directed antibody-drug conjugate, alone and in combination with an anti-PD-1 Ab, in dose escalation (Phase 1) followed by dose expansion (Phase 2). The study population in dose escalation (Phase 1) consists of patients with advanced solid tumors refractory to standard of care, or for whom no standard of care exists. After the MTD and/or RP2D for single agent LCB84 is determined, dose escalation cohorts with select tumor types will be enrolled. Combination LCB84 and anti-PD-1 Ab will be evaluated in dose escalation after a minimum of 2 dose levels of single agent LCB84 have established DLT safety, to determine the MTD and/or RP2D of combination LCB84 and anti-PD-1 Ab, and to continue into dose expansion cohorts in select tumor types.

A Phase 1/2 Study to Evaluate the Safety, Tolerability, and Efficacy of TROP2-Directed Antibody-Drug Conjugate LCB84, as a Single Agent and in Combination With an Anti-PD-1 Ab, in Patients With Advanced Solid Tumors

  3. * Prior treatment with TROP2-directed therapy is permitted.
  4. * Measurable disease as defined by RECIST v1.1 or RANO-BM.
  5. * Willingness to provide archival tumor tissue when available or to undergo pre-treatment biopsy if not available.
  6. * Mandatory pre- and on-treatment biopsies for enrichment cohorts in Phase 1 dose escalation and Phase 2 expansion cohorts if deemed medically feasible and safe.
  7. * Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
  8. * Adequate organ function as defined by:

  10. * Platelets ≥100.0 x 109/L (100 000/µL)
  11. * Hemoglobin ≥9.0 g/dL
  12. * Aspartate aminotransferase (AST) ≤2.5 x ULN; alanine aminotransferase (ALT) ≤2.5 x ULN (AST, ALT ≤5 x ULN if liver metastases present)
  1. * Active or progressing central nervous system (CNS) metastases or any evidence of leptomeningeal disease.
  2. * Persistent toxicities from previous systemic antineoplastic treatments \>Grade 1, excluding alopecia and vitiligo.
  3. * Systemic antineoplastic therapy (including antiestrogen therapy) within 5 half-lives or 4 weeks, whichever is shorter, prior to first dose of the study drug.
  4. * Concomitant use of systemic steroids at dose of \>10 mg of prednisone or its equivalent per day (exception for brain metastases, as described in exclusion criteria #1 above).
