Positive Results of Clinical Trial Comparing Coherus? Ranibizumab Biosimilar Candidate CHS-201 to Reference Product Lucentis (Ranibizumab) in the Treatment of Neovascular (Wet) Age-Related Ma

Coherus BioSciences, Inc.?(?Coherus?, Nasdaq: CHRS) today announced that positive results from the pivotal COLUMBUS-AMD clinical trial evaluating and comparing the efficacy and safety between CHS-201 and Lucentis? (ranibizumab) in the treatment of neovascular (wet) age-related macular degeneration (nAMD) were presented October 1st?by Dr. Peter K. Kaiser, Professor of Ophthalmology at the Cole Eye Institute of the Cleveland Clinic, at the 54th?Annual Scientific Meeting of the Retina Society.? The COLUMBUS-AMD study demonstrated the similarity of CHS-201 and reference product Lucentis in terms of clinical efficacy, safety, and immunogenicity in patients with newly diagnosed subfoveal nAMD.

?Neovascular age-related macular degeneration destroys the sharp, central vision needed to see clearly and can affect daily activities like reading, driving, and watching television. It is responsible for more than 90 percent of AMD-related severe visual loss which has a significant deleterious impact on a patient?s quality of life,? said Dr. Kaiser. ?These findings reinforce our confidence that CHS-201 delivers outcomes and safety profile similar to the reference product.? ?CHS-201 is another example of our commitment to bring patients and providers choice without compromise, and, if approved, will enable retinal specialists to make a proven, safe, and essential therapy accessible to more patients with retinal vascular disorders,? said Denny Lanfear, Coherus CEO. CHS-201 (also known as FYB201) is being developed as a proposed biosimilar to the reference product, Lucentis? (ranibizumab). In 2019, Coherus BioSciences acquired the exclusive rights from Bioeq AG, a Swiss biopharmaceutical joint venture between the Str?ngmann Group and the Polpharma Biologics Group, to commercialize CHS-201 in the United States. In August 2021, Bioeq submitted the CHS-201 biologics license application (BLA) to the U.S. Food and Drug Administration (FDA). FDA has accepted the BLA filing for review and set a target action date for August 2, 2022. If approved, Coherus expects to begin marketing CHS-201 in the United States in the second half of 2022. About the COLUMBUS-AMD Study A total of 477 patients with newly diagnosed subfoveal nAMD were randomized 1:1 to receive CHS-201 or reference Lucentis every four weeks for up to 48 weeks. The primary endpoint of the study was change from baseline in best corrected visual acuity (BCVA) measured by Early Treatment Diabetic Retinopathy Study (ETDRS) letters after 8 weeks. Secondary endpoints included change from baseline in BCVA at 48 weeks, change from baseline in FCB retinal thickness at 48 weeks, safety and immunogenicity. The study results demonstrated a mean BCVA improvement from baseline at eight weeks with an equal median change of 5.0 ETDRS letters for both CHS-201 and Lucentis? treatment groups. The mean change (SD) was 5.1 (7.52) ETDRS letters for CHS-201 and 5.6 (8.63) for Lucentis in the full analysis set population. Analysis of Covariance (ANCOVA) least squares mean difference for the change from baseline in BCVA at week eight between CHS-201 and Lucentis was -0.4 ETDRS letters, with a 90 percent confidence interval of -1.6 to 0.9, well within the predefined equivalence margin of -3.5 to 3.5. Patients in both treatment groups experienced similar reductions in foveal center point (FCP) and foveal central subfield (FCS) retinal thickness, as well as total lesion area. Reduction in the proportion of patients with active CNV leakage and increase in the proportion of patients with a fluid-free macula were similar in both treatment groups. Overall, the frequency and type of ocular adverse events (AEs), including rates of intraocular inflammation, were comparable between the treatment groups. Most AEs were of mild or moderate intensity, and no clinically meaningful differences were identified. CHS-201 and Lucentis had comparable immunogenicity profiles. Results of the study were published?online?in May 2021 in Ophthalmology.
