Monday morning’s press atmosphere produced a shower of announcements from ERYTECH and the Janssen Pharmaceutical Companies of Johnson & Johnson, as each reported the results of their respective research. Based in France, ERYTECH is a clinical-stage biopharmaceutical company focused on using its proprietary ERYCAPS platform to develop creative therapies for rare cancers and orphan diseases. Eryaspase, its chief therapeutic candidate, was recently studied in a Phase III clinical trial as a treatment for second-line advanced pancreatic cancer. While the trial ultimately did not meet its primary endpoint of overall survival, patients treated with eryaspase demonstrated better disease control than patients treated only with chemotherapy. Additionally, eryaspase’s safety pro consistent with the results of previous clinical trials and safety reviews. A subgroup of patients treated with eryaspase and an irinotecan-based chemotherapy showed a trend of small but noticeable survival benefit. However, patients being treated with gemcitabine and nabpaclitaxel did not exhibit any survival benefit from the addition of eryaspase, a contrast which ERYTECH noted might deserve further investigation. The company now plans to focus on its late-stage program in acute lymphoblastic leukemia (ALL) and continue to work toward approval in hypersensitive ALL based on the promising results of its Phase II trial. This is in accordance with the company’s original plan to submit a Biologics License Application before the end of 2021. Meanwhile, Janssen reported analyses in which STELARA® (ustekinumab), an interleukin (IL)-12 and IL-23 inhibitor, is showing promising results as a first-line therapy for Crohn’s Disease (CD) and Ulcerative Colitis (UC) in bio-naïve patients. This announcement referenced two different studies involving STELARA: the first as a treatment for UC, and the second as a treatment for CD. “These analyses in ulcerative colitis and Crohn’s disease expand the body of data for STELARA and give us insight into treatment sequencing and persistence rates, which are important when assessing biologic therapy options for patients. The data are informative because patients with inflammatory bowel disease can demonstrate a short-term clinical response and improvement with therapy and then lose response,” said Dr. Jan Wehkamp, M.D., vice president and gastroenterology disease area leader at Janssen Research & Development. The results of the UC study suggested that STELARA is more effective as a first-line advanced therapy than as a second or third-line therapy. This was reflected by the amount of time a patient spent in remission or response, as well as the postponing of surgery. When used as a first-line treatment, STELARA patients spent about 8.5 months in remission over one year, 23.1 months over three years and 32.2 months over five years. However, when used as a second-line treatment, STELARA patients only spent about 7.9 months in remission over one year, 14.5 months over three years and just 17.5 months over five years. The second study in CD suggested that a higher proportion of patients who started on STELARA were persistent on therapy than patients who started on adalimumab. This includes patients who were persistent on therapy and corticosteroid-free, as well as patients who were persistent and on monotherapy. Patients who started on STELARA rather than adalimumab had a 50% higher rate of persistence, a 17% higher rate of persistence and being corticosteroid-free and a 47% higher rate of persistence on monotherapy.

SOUTH SAN FRANCISCO, Calif., July 09, 2021 (GLOBE NEWSWIRE) -- Surrozen, Inc., a biotechnology company discovering and developing drug candidates to selectively modulate the Wnt pathway, announced today that new data from its inflammatory bowel disease (IBD) program, including preclinical studies of SZN-1326 showing superior activity compared to therapeutics currently used in treatment, were presented during the 16th Congress of the European Crohn’s and Colitis Organisation. Two poster presentations discussed data from studies of SZN-1326, a bi-specific full-length human antibody targeting Fzd5/8 and Lrp6 receptors in development for the treatment of IBD. A third poster presentation discussed expression profiling of Wnt pathway genes in colon biopsies from patients with ulcerative colitis (UC). Copies of posters will be available in the Investors & Media section of Surrozen’s website. “In both chronic and acute models presented at this congress, SZN-1326 demonstrated beneficial activity compared to other therapeutics currently used for the treatment of IBD that we believe could be meaningful for patients living with IBD,” said Craig Parker, President and Chief Executive Officer of Surrozen. “Combined with presented data about Wnt expression and our other studies of SZN-1326, we continue to be excited for this program and look forward to moving it into clinical investigation in 2022.” In a poster presentation titled, “SZN-1326, a Wnt agonist, improved epithelial healing and ameliorated colitis in a chronic DSS model, in stark contrast to anti-TNFa and anti-IL-12/23p40 antibodies,” findings from a chronic mouse IBD model showed SZN-1326 at various dosing regimens stimulated intestinal epithelial regeneration, induced mucosal healing and restored the epithelial barrier resulting in reduced inflammation, reduced serum cytokine levels, improved body weight and reduced disease activity. In contrast, treatment with anti-TNFa or anti-IL-12/23p40 antibodies led to reduction only in certain serum inflammatory cytokines but had no effect on disease activity or colon histology in this model. In a poster presentation titled, “SZN-1326, a Wnt signal activator, is more efficacious than cyclosporine A in an acute DSS model,” findings from an acute mouse IBD model showed SZN-1326 at various dosing regimens stimulated intestinal epithelial regeneration, induced mucosal healing and restored the epithelial barrier resulting in reduced inflammation, reduced serum cytokine and lipocalin-2 levels improved body weight and reduced disease activity. In comparison, Cyclosporine A showed only a mild effect on reducing disease activity and lipocalin-2. In a poster presentation titled, “Expression profiling of Wnt pathway genes in colon biopsies of patients with ulcerative colitis,” shows reduced expression of Wnt receptors, RSPOs and Wnt target genes indicated insufficient Wnt signal induction in the damaged colon epithelium of UC patients. The findings suggest that repair of the damaged epithelium by Wnt agonist treatment may constitute a new mechanism of action and benefit patients with UC. About Wnt Signaling Wnt signaling plays key roles in the control of development, homeostasis, and regeneration of many essential organs and tissues, including liver, intestine, lung, kidney, retina, central nervous system, cochlea, bone, and others. Modulation of Wnt signaling pathways has potential for treatment of degenerative diseases and tissue injuries. Surrozen’s platform and proprietary technologies have the potential to overcome the limitations in pursuing the Wnt pathway as a therapeutic strategy. About Surrozen Surrozen is a biotechnology company discovering and developing drug candidates to selectively modulate the Wnt pathway. Surrozen is developing tissue-specific antibodies designed to engage the body’s existing biological repair mechanisms with potential application across multiple disease areas, including inflammatory bowel disease, hepatitis, eye diseases, hearing loss, lung and airway diseases, and certain neurological disorders.
