Data Presented at ENDO 2021 Differentiate LUM-201 from General Growth Hormone Secretagogues and Additional Support LUM-201’s Potential as Therapeutic for Pediatric Growth Hormone Deficiency Nasdaq: LUMO

AUSTIN, Texas, March 20, 2021 (GLOBE NEWSWIRE) – Lumos Pharma, Inc. (NASDAQ: LUMO), a clinical-grade biopharmaceutical company dedicated to medical treatment for rare diseases, poster 7102 with the title, “LUM-201 Has a Larger GH Response than General GH Secretagogues in Pediatric Growth Hormone Deficiency, ” presented by the authors Bright, G., et al in Poster Session 33 at ENDO 2021, Annual Meeting of the Endocrine Society, taking place almost from March 20-23, 2021. The poster can be viewed on the ENDO website and can also be viewed on the Company’s website there in the Investors & Media section, under “Posters & Publications.”

“These data presented today at the Annual Meeting of the Endocrine Association highlight the unique ability of LUM-201 to stimulate higher GH levels significantly higher than those produced by conventional GH secrets. , ”Said John McKew, PhD, Chief Operating Officer and Chief Scientific Officer of Lumos Pharma. “Along with previously published data by Nass, et al showing the effect of 24-hour PD measured by GH release in adults taking LUM-201 shows that LUM-201 is very different from other secrets in terms of its ability to be used effectively. therapeutic. These results support data analyzes by Bright, et al and Blum, et al recently published in the Journal of the Endocrine Society demonstrates the ability of LUM-201 to have a therapeutic response in pediatric patients with moderate growth hormone deficiency, or 60% of the total PGHD population, as indicated by our specific predictive enrichment symptoms and increased confidence give us in potential LUM efficiency. -201 in this patient population. “

Poster 7102 provides an analysis of data from a preliminary clinical study comparing the maximum growth hormone (GH) response of LUM-201 (formerly MK-0677) with the response of normal GH secretions (clonidine, arginine , L-dopa, glucagon, insulin) in naïve-to-treatment children, previously diagnosed with growth hormone deficiency (GHD). The goal was to determine whether LUM-201 stimulates different GH responses from normal GH secretagogues. In this study, 68 oral prepubertal children with GHD were given a single oral dose of 0.8 mg / kg of LUM-201 with a median baseline age of 9.2 years, SDS height of -3.3, preoperative height (HV) of 4.0 cm / yr, and an IGF-1 baseline of 51 ng / mL. The results showed a maximum median GH response to a single oral LUM-201 dose of 15.0 ng / mL, a statistically significant difference compared to a peak response of 5.4 ng / mL GH to different pairs of standard GH stimulation tests. (p <0.00001). In a multivariate study (r2 = 0.73) differentiated GH increased with higher baseline values ​​of IGF-1 (p <0.00001) and normal GH stimulation test (p = 0.047) but no effect on age (p = 0.16), gender (p = 0.28), baseline HV (p = 0.24), bone-age differences (p = 0.33) or SDS-height (p = 0.75).

The analysis shows that, in children with GHD, GH response to a single oral dose of LUM-201 is significantly higher than that observed with normal GH stimulant agents. The difference in GH responses increases with higher baseline concentrations of IGF-1 and higher GH stimulation test results. The synergistic actions of LUM-201 on the psychosocial mechanisms that regulate GH release explain why GH responses are greater in response to LUM-201 compared to traditional experiments used for Determining PGHD and showing that the greatest differences are found in children with more moderate levels of GHD.
