The oral presentation will highlight data from the approximately 30 patients in the 100mg daily monotherapy expansion cohort of ARC-20, a Phase 1/1b study evaluating casdatifan in late-line ccRCC. It will include data on safety and efficacy, including objective response rate and rate of primary progression, as well as other data to assess the depth and duration of responses. The presentation will also highlight data from the 50mg monotherapy expansion cohort of approximately 30 patients in the same setting.

"We are thrilled to be presenting the first clinical efficacy data from the ARC-20 study for our HIF-2a inhibitor, casdatifan, in an oral plenary session, as well as two additional posters that further highlight the differentiation of casdatifan in ccRCC and the therapeutic opportunities in other tumor types," said Terry Rosen, Ph.D., chief executive officer of Arcus. "These data support a potential best-in-class profile, and we are rapidly advancing a differentiated development program for casdatifan, including the planned initiation of our first Phase 3 study in the first half of 2025."

Arcus is pursuing a broad development program in both the first-line and post-anti-PD-1 settings with differentiated combinations to maximize the opportunity for casdatifan in ccRCC. In addition to the monotherapy cohorts of ARC-20, the study is also enrolling a cohort to evaluate casdatifan in combination with cabozantinib, a VEGFR tyrosine kinase inhibitor, which is intended to support the initiation of Arcus’s first Phase 3 study, PEAK-1, evaluating casdatifan in combination with cabozantinib versus cabozantinib monotherapy in patients with metastatic ccRCC who have previously received anti-PD-1 therapy. The primary endpoint will be progression-free survival with a key secondary endpoint of overall survival. Arcus also recently announced a clinical collaboration as part of its first-line strategy in advanced first-line ccRCC to evaluate casdatifan in combination with volrustomig, an investigational PD-1/CTLA-4 bispecific antibody.

About AU-007
AU-007 is a computationally designed, human IgG1 monoclonal antibody that is highly selective to the CD25-binding portion of IL-2. With a mechanism of action unlike any other IL-2 therapeutic in development, AU-007 leverages IL-2 to reinforce anti-tumor immune effects. This is achieved by preventing IL-2, either exogenous or secreted by effector T cells, from binding to trimeric receptors on regulatory T cells while still allowing IL-2 to bind and expand effector T cells and NK cells. This prevents the negative feedback loop caused by other IL-2-based treatments and biases the immune system toward activation over suppression. AU-007 also prevents IL-2 from binding to CD25-containing receptors on eosinophils, as well as vasculature and pulmonary endothelium, which may significantly reduce the vascular leak syndrome and pulmonary edema associated with high-dose IL-2 therapy.

DLL3 is overexpressed in many neuroendocrine tumors, including SCLC, and is typically associated with poor clinical outcomes. ZL-1310 comprises a humanized anti-DLL3 antibody and a novel camptothecin derivative as its payload. The compound was designed with a novel linker-payload platform called TMALIN, which leverages the tumor microenvironment to overcome challenges associated with first-generation ADC therapies.

"New therapies that reduce off-target toxicity and increase anti-tumor effectiveness are critically needed to improve treatment options for many cancer patients, including SCLC and other tumors of neuroendocrine origin," said Rafael G. Amado, M.D., President, Head of Global Research and Development, Zai Lab. "ZL-1310 is an example of our company’s commitment to progressing a differentiated global oncology pipeline that will help fill these types of treatment gaps and provide meaningful benefit to patients. We look forward to sharing preliminary results from the Phase 1 study of this exciting next-generation ADC at ENA 2024."

Details regarding the ZL-1310 oral presentation at ENA 2024 are as follows:

As previously announced, Phanes is conducting this study under a clinical trial collaboration agreement with Merck (known as MSD outside the US and Canada). PT886 is a first-in-class native IgG-like bispecific antibody (bsAb) targeting claudin 18.2 and CD47. It was granted orphan drug designation (ODD) for the treatment of pancreatic cancer by the FDA in 2022 and Fast Track designation for the treatment of patients with metastatic claudin 18.2-positive pancreatic adenocarcinoma earlier this year. PT886 is currently being evaluated as monotherapy and in combination with pembrolizumab, or with chemotherapy, either alone or in combination with pembrolizumab.

The multi-center Phase I/II clinical trial of PT886 (NCT05482893), known as the TWINPEAK study, is currently evaluating the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of PT886 in patients with locally advanced or metastatic gastric, gastroesophageal junction and pancreatic cancers. A Phase I clinical trial of PT886 is also ongoing in China (CTR20241655).
