ClinicaliQ Trial Snapshot
  • LEGEND Study: EG-70 in NMIBC Patients BCG-Unresponsive and High-Risk NMIBC Incompletely Treated With BCG or BCG-Naïve — Recruiting • Phase I • Oncology • NCT04752722.
  • What is being tested: EG-70 is an intravesical immunotherapy being evaluated for safety and efficacy in non-muscle invasive bladder cancer (NMIBC), with a Phase 1 dose-escalation design to establish optimal dosing and safety profile.
  • Patient eligibility overview: The trial recruits patients with high-risk NMIBC who are BCG-unresponsive, incompletely treated with BCG, or BCG-Phase Iïve, addressing a significant clinical gap for those failing or ineligible for standard BCG therapy.

What This Trial Is Studying

This study will evaluate the safety and efficacy of intravesical administration of EG-70 in the bladder and its effect on bladder tumors in patients with NMIBC. This study study consists of two phases; a Phase 1 dose-escalation to establish safety and recommended the phase 2 dose, followed by a Phase 2 study to establish how effective the treatment is. The Study will include patients with NMIBC with Cis for whom BCG therapy is unresponsive and patients with NMIBC with Cis who are BCG-naïve or inadequately treated.

Eligibility Snapshot
  • : BCG-unresponsive Patients: 1. BCG-unresponsive NMIBC with carcinoma in situ (CIS) with or without coexisting papillary Ta/T1 tumors who are ineligible for or have elected not to undergo cystectomy, and have experienced CIS disease within 12 months of treatment where: adequate BCG regimen consists of at least 2 courses of BCG where the first course (induction) must have included at least 5 or 6 doses and the second course may have included a re-induction (at least 2 treatments) or maintenance (at least 2 doses), and Cis must be documented or indicated by pathology Phase 2 Only: 2. BCG-Naïve or BCG-incompletely treated Patients with CIS or BCG-unresponsive, HG Ta/T1 papillary disease without CIS: -NMIBC with current Cis of the bladder, with or without coexisting papillary Ta/T1 NMIBC tumor(s), who are ineligible for or have elected not to undergo cystectomy, where: either: cohort 2a) no treatment with BCG but may have previously been treated with at least 1 dose of intravesical chemotherapy following transurethral resection of bladder tumor (TURBT) and Cis must be documented or cohort 2b) indicated by pathology incomplete BCG treatment (at least 1 dose and less than the 5+2 doses required for adequate dosing per Cohort 1) or…
