Encouraging antitumor activity in heavily pretreated population during dose finding
Well tolerated across broad dose range in phase 1 first-in-human study
Poster Presentation at ASCO on June 3, 8:00-11:00 a.m. CT
LOS ANGELES, CA, USA I June 1, 2023 I TORL BioTherapeutics LLC ("TORL Bio" or "the Company") announces the initial results from an ongoing phase I study of their claudin 6 (CLDN6) targeted antibody drug conjugate (ADC), TORL-1-23, in patients with advanced cancer on the American Society of Oncology (ASCO) website : https://meetings.asco.org/meetings/2023-asco-annual-meeting/299/program-guide/scheduled-sessions#date-6/3/2023. The poster presentation (ASCO Abstract 3082) of the TORL123-001 (TRIO-049) trial will include updated data through the 2.4mg/kg dose level and will be presented by the Global Principal Investigator, Dr. Gottfried Konecny of the University of California Los Angeles (UCLA) Medical Center.
Twenty-five (25) patients with heavily pretreated (an average of 5 prior lines of therapy) metastatic ovarian (n=19), testicular (n=3), and endometrial (n=3) cancers were enrolled and evaluable for safety and efficacy across 8 dose levels ranging from 0.2 to 2.4 mg/kg IV every 3 weeks. "We are excited to provide the first clinical data with TORL-1-23, a novel claudin 6 targeted ADC" stated Dave Licata, CEO and Co-Founder of TORL Bio. "We are very encouraged by the current TORL-1-23 efficacy and safety data indicating that this drug could represent a new potential treatment for patients with ovarian and other CLDN6+ cancers" said Dennis Slamon, MD, PhD, and Co-Founder of TORL Bio.
Key study findings include:
Expansion cohorts are planned in CLDN6+ ovarian cancerCLDN6+ ovarian cancer and non-small cell lung cancer (NSCLC), and other CLDN6+ cancers upon determination of the recommended phase 2 dose (RP2D).

About TORL-1-23
TORL-1-23 is an anti-CLDN6 humanized monoclonal antibody coupled to MMAE via a cleavable linker. CLDN6 is overexpressed in multiple cancers with limited to no detectable expression in normal tissues, thus an ideal target for an ADC. TORL 1-23 is highly selective; in vitro TORL-1-23 exhibited robust and selective binding to CLDN6-overexpressing cell lines without binding to cell lines over-expressing other claudins, such as CLDN3, CLDN4, and CLDN9. TORL-1-23 is in clinical trials for treatment of CLDN6+ cancers including ovarian cancer and NSCLC.
About TORL123-001 (TRIO-049) Clinical Study
TORL BioTherapeutics is currently enrolling patients in a phase I study, TORL123-001 (TRIO-049), to assess the safety, pharmacokinetics, biomarkers, and antitumor activity of TORL-1-23. Further details including current study sites can be found at https://clinicaltrials.gov/show/NCT05103683
