"Data at AACR (Free AACR Whitepaper) from our clinical development program support the potential of our methylation-based technology platform to transform cancer detection and care for people across all stages of their cancer journey," said Josh Ofman, MD, MSHS, president at GRAIL. "In addition to case studies of our GalleriⓇ multi-cancer early detection test in clinical practice, and demonstrating the unmet need for patients presenting with non-specific symptoms suggestive of cancer, we are excited to share results evaluating the performance of our new research-use only, methylation-based solution for post-diagnosis applications."

In the early-diagnosis setting, GRAIL will present real-world case studies of the Galleri multi-cancer early detection (MCED) test that demonstrate how Galleri led to early detection and treatment of cancer in asymptomatic individuals and directed diagnostic evaluation. In these instances, the Galleri test allowed the cancers to be detected in early stages and before clinical presentation.

In the post-diagnosis setting, analytical validation data will show how GRAIL’s targeted methylation technology platform can be used for diagnostic decision support to aid in achieving timely and cost-effective management of patients and after cancer diagnosis. GRAIL will present results from an analytical validation of its research-use only technology solution to accelerate cancer research in the post-diagnosis setting, launched as an offering to biopharmaceutical companies in January 2023. Potential research use cases for the methylation-based solution include, but are not limited to, prognosis, minimal residual disease detection, and recurrence monitoring across different cancer types.

"Dosing of the first patient with HST-1011 is an important milestone for HotSpot signifying our evolution into a clinical-stage company with the first-in-human dosing of a product candidate derived from our proprietary Smart Allosterydrug discovery platform," said Tim Reilly, Ph.D., Chief Development Officer of HotSpot. "Importantly, we believe that HST-1011, as a highly potent and selective inhibitor of the long sought after target CBL-B, may represent an important new immunotherapy treatment option for cancer patients."

The Phase 1/2 study of HST-1011 is an open-label clinical study designed to evaluate HST-1011 alone and subsequently in combination with Regeneron’s anti-PD-1 therapy, Libtayo (cemiplimab), in patients with advanced solid tumors that are relapsed on or are refractory to anti-PD(L)-1 or standard of care therapies. Additional information on this clinical trial can be found on www.clinicaltrials.gov (NCT05662397). The combination therapy component of the study is enabled by a clinical supply agreement with Regeneron for provision of Libtayo.

"Despite tremendous progress in the field of immuno-oncology (I-O), significant unmet need persists for patients with advanced solid tumors, as many cancers are found to be unresponsive to or lack durable responses following treatment with currently available therapies," said Jason Luke, M.D., F.A.C.P., Director of the Immunotherapy and Drug Development Center at the University of Pittsburgh Medical Center’s Hillman Cancer Center and the lead Principle Investigator on HotSpot’s ongoing Phase 1/2 clinical study. "We believe CBL-B’s role as a master regulator of immune cell activation presents a differentiated therapeutic opportunity. We are excited to explore this novel mechanism and new I-O treatment in collaboration with HotSpot and the other investigators and sites participating in this trial."

HotSpot will be presenting the HST-1011 first-in-human Phase 1/2 clinical trial design at the upcoming American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2023, taking place in Orlando, Florida, during the Clinical Trials in Progress poster session. The details for the presentation are as follows:

Title: Phase 1/2 study of HST-1011, an oral CBL-B inhibitor, alone and in combination with anti-PD-1 in patients with advanced solid tumors
Session Title: Phase I and First-in-Human Clinical Trials in Progress
Session Date and Time: Tue., Apr. 18, 1:30-5:00 PM ET
Location: Poster Section 46
Poster Board Number: 14
Abstract Number: CT251

About HST-1011
HST-1011 is an investigational orally bioavailable, selective, small molecule allosteric inhibitor of CBL-B, an E3 ubiquitin protein ligase critically involved in immune cell response. Because CBL-B functions as a master regulator of effector cell (T cell and natural killer cell) immunity, its inactivation removes its endogenous negative regulatory functions to substantially enhance anti-tumor immunity. Preclinical data has demonstrated HST-1011’s ability to bind to and inhibit a natural hotspot on CBL-B, yielding the activation and propagation of a targeted anti-tumor immune response. Enabled by HotSpot’s proprietary Smart Allostery platform, HST-1011 is designed with tight binding, low nanomolar potency, a slow dissociation rate from the target to enable sustained pharmacology, and greater selectivity for CBL-B relative to C-CBL.

Session Category: Experimental and Molecular Therapeutics
Session Date and Time: Wednesday Apr 19, 2023, 9:00 AM – 12:30 PM
Location: Poster Section 21
Poster Board Number: 27
Published Abstract Number: 6320

The abstract is available here and the Poster will be available on the OnCusp website shortly after the presentation.

"We are very excited to present data highlighting the exciting preclinical profile of CUSP06, a differentiated, potential global second-in-class CDH6 ADC, as we pivot to become a clinical stage company this year" stated Eric Slosberg, PhD, Chief Development Officer and co-founder of OnCusp Therapeutics.

About CUSP06:

CUSP06, a preclinical-stage CDH6 ADC, is composed of a proprietary antibody with high CDH6 binding affinity, a protease cleavable linker, and an exatecan payload (a potent and clinically validated topoisomerase-1 inhibitor). The linker is specially designed to complement the exatecan payload, generating a highly stable and homogenous ADC. The payload is a weak substrate for BCRP/Pgp. In preclinical data, this linker/payload has been shown to enable a stronger "bystander effect" than competitor ADCs. CUSP06 has a drug-to-antibody ratio of 8. OnCusp obtained the exclusive global rights (ex-China) to lead the development and commercialization of CUSP06, from Multitude Therapeutics.
