Hansa Biopharma announces encouraging high-level results for first-in-human trial of HNSA-5487

On October 9, 2023 Hansa Biopharma, "Hansa" (Nasdaq Stockholm: HNSA), a pioneer in enzyme technology for rare immunological conditions, reported high-level results from NICE-01, the first-in-human trial for HNSA-5487 (Press release, Hansa Biopharma, OCT 9, 2023, View Source [SID1234635724]). Results showed the molecule was safe and well tolerated. Fast and complete depletion of immunoglobulin G (IgG) antibodies was observed at increasing doses in all subjects. Pharmacokinetics (PK) was in line with expectations and pharmacodynamics (PD) (efficacy on IgG cleavage) showed a fast and complete cleavage of IgG to F(ab’)2- and Fc-fragments with increasing doses.

NICE-01 is a double blind, randomized, placebo-controlled trial evaluating safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of single ascending doses of HNSA-5487 administered as a single intravenous (IV) infusion. The trial included a total of 36 healthy male and female adult participants.

HNSA-5487 is the company’s lead candidate in the Novel Immunoglobulin Cleaving Enzymes for Repeat Dosing (NiceR) program. The NiceR program aims to develop next-generation enzymes with lower immunogenicity that would potentially allow for repeat dosing in a range of indications including IgG-driven autoimmune diseases where patients experience flares, transplantation where repeat dosing would be beneficial, gene therapy and oncology.

Søren Tulstrup, President and CEO, Hansa Biopharma said, "This is encouraging data as we continue to explore the potential for HNSA-5487 and better understand how this powerful, new enzyme could benefit patients and clinicians. An enzyme with lower immunogenicity would potentially enable repeat dosing, allowing a prolonged effect by flexibly extending the IgG-free window depending on the number of repeated infusions. This could enable innovative treatment approaches in a broad range of indications, and benefit patients with diseases where a prolonged IgG-free window is needed".

Analysis of additional exploratory endpoints on IgG recovery and immunogenicity is now being conducted, with follow up on all subjects for 12 months. This analysis will serve as key input in determining the further clinical development program, including selection of indications.

About the BLUE-C Study
BLUE-C was a multi-center, prospective study (NCT04144738) of more than 20,000 adults 40 years of age and older. The trial was designed to evaluate the performance of next-generation Cologuard (multi-target stool DNA or mt-sDNA). Using colonoscopy as a reference method, the robust study design compared next-generation Cologuard and a fecal immunochemical test (FIT). Blood samples were also collected for later evaluation of a blood-based screening test being developed by Exact Sciences. BLUE-C is one of the largest colorectal cancer screening trials ever conducted, and the study population reflects the racial and ethnic makeup of the United States according to the 2020 census.

About Next-Generation Cologuard
Developed in partnership with Mayo Clinic, next-generation Cologuard features novel biomarkers and improved laboratory processes. It also incorporates enhanced sample stability components to provide patients more time to return their sample to Exact Sciences’ lab and increase the valid result rate.

Cologuard revolutionized colorectal cancer screening by providing a convenient and accurate testing option for those at average risk. Nearly a decade later, Cologuard has been used to screen for colorectal cancer more than 12 million times.

In the coming months, Exact Sciences plans to release additional analyses of the BLUE-C data and complete its application to the FDA for approval of next-generation Cologuard.

About Cologuard
Results from Exact Sciences’ prospective, 90-site, point-in-time, 10,000-patient pivotal trial, DeeP-C, were published in the New England Journal of Medicine in March 2014. The Cologuard test is included in the American Cancer Society’s (2018) colorectal cancer screening guidelines and the recommendations of the U.S. Preventive Services Task Force (2021) and National Comprehensive Cancer Network (2023). The Cologuard test is indicated to screen adults 45 years of age and older who are at average risk for colorectal cancer by detecting certain DNA markers and blood in the stool. Do not use the Cologuard test if you have had precancer, have inflammatory bowel disease and certain hereditary syndromes, or have a personal or family history of colorectal cancer. The Cologuard test is not a replacement for colonoscopy in high-risk patients. The Cologuard test performance in adults ages 45-49 is estimated based on a large clinical study of patients 50 and older. The Cologuard test performance in repeat testing has not been evaluated.

The Cologuard test result should be interpreted with caution. A positive test result does not confirm the presence of cancer. Patients with a positive test result should be referred for colonoscopy. A negative test result does not confirm the absence of cancer. Patients with a negative test result should discuss with their doctor when they need to be tested again. Medicare and most major insurers cover the Cologuard test. For more information about the Cologuard test, visit cologuard.com. Rx only.

AACR Ovarian Cancer Conference Presentation

On October 9, 2023 Amplia Therapeutics reported that poster presentation delivered by Professor Dwayne Stupack from the University of California, San Diego at the AACR (Free AACR Whitepaper) Special Conference in Cancer Research: Ovarian Cancer has shared the findings of new preclinical studies that support the potential of our FAK inhibitor, narmafotinib (AMP945), in the treatment of high-grade serous ovarian cancer (Press release, Amplia Therapeutics, OCT 9, 2023, View Source [SID1234635714]).

The data shows that narmafotinib is active in mouse models of ovarian cancer, with improved activity and tolerability compared to PARP inhibitors – the current standard-of-care. Furthermore, it shows promising activity in a model unresponsive to these inhibitors. This builds on Prof. Stupack’s previous research demonstrating that inhibition of the FAK enzyme can make chemotherapy and immunotherapy more effective in tough-to-treat ovarian cancers.

Each year over 1000 women in Australia die from ovarian cancer, indicating a clear need for better treatments.

Amplia CEO and MD, Dr Chris Burns, commented:

"The research results presented today by Prof. Stupack are extremely exciting and clearly demonstrate that our best-in-class FAK inhibitor narmafotinib has significant potential in the treatment of ovarian cancer."
