AUSTIN, Texas, March 01, 2023 (GLOBE NEWSWIRE) -- Lumos Pharma, Inc. (NASDAQ:LUMO), a clinical-stage biopharmaceutical company focused on therapeutics for rare diseases, today announced financial results for the year ended December 31, 2022.

“We are pleased with the progress we made in 2022 advancing two Phase 2 OraGrowtH Trials evaluating our oral therapeutic candidate, LUM-201, in idiopathic PGHD,” said Rick Hawkins, Chairman and CEO of Lumos Pharma. “Furthermore, with both the OraGrowtH210 and OraGrowtH212 Trials now fully enrolled, we look forward to completing these trials and announcing top line results in the fourth quarter of 2023. We continue to advance our LUM-201 clinical program and plan for our pivotal Phase 3 trial for potentially the first oral therapeutic for PGHD.”

Recent Highlights

• Patient Enrollment Completed in Two Phase 2 OraGrowtH Trials Evaluating Oral LUM-201 in Idiopathic (moderate) PGHD. The last subjects have been randomized in our OraGrowtH210 and OraGrowtH212 Trials, and we now expect primary outcome data on 82 subjects in the OraGrowtH210 Trial and 22 subjects in the PK/PD OraGrowtH212 Trial in the fourth quarter of 2023.
  
  
• Interim analyses for Phase 2 OraGrowtH210 and PK/PD OraGrowtH212 Trials announced November 2022. Data from the interim analysis of our OraGrowtH210 Trial showed LUM-201 met growth expectations, showed durable response and was well-tolerated. Data support the selection of 1.6 mg/kg/day as the optimal dose for our pivotal Phase 3 trial. The control arm for this interim analysis included outliers with growth greater than prior data precedents, the impact of which we expect to diminish with full enrollment. Interim data from our OraGrowtH212 Trial were supportive of the OraGrowtH210 Trial data.
  
  
• Key Opinion Leaders encouraged by interim OraGrowtH Trials data. We hosted a webinar featuring Drs. Andrew Dauber and Fernando Cassorla, distinguished opinion leaders in the field of pediatric endocrinology, for a discussion of the interim data from our Phase 2 OraGrowtH210 and PK/PD OraGrowtH212 Trials. A replay of the event is available in the “Events & Presentations” section under “Investors & Media” on our website.
  
  
• Pilot Investigator-Initiated Trial evaluating LUM-201 in NAFLD supported by prior data. As previously announced, we entered into a clinical collaboration with Dr. Laura Dichtel and Massachusetts General Hospital to explore the potential of LUM-201 in Nonalcoholic Fatty Liver Disease (NAFLD) in an investigator sponsored pilot study. Encouraging data presented by Dr. Dichtel at ENDO 2022 (abstract) evaluating injectable growth hormone in NAFLD supported the assessment of oral LUM-201 in the same indication. Enrollment in the trial is ongoing.
  
  
• Additional Data on LUM-201 OraGrowtH Trials to be presented in an oral and a poster presentation at the 2023 International Meeting of Pediatric Endocrinology (IMPE) in Buenos Aires, Argentina March 4-7, 2023. We are pleased to have two abstracts accepted for presentation at the upcoming IMPE meeting. Details are as follows:
  
  
  • Oral Presentation - Dose-dependent Increase in GH AUC_0-12h with LUM-201 in Idiopathic Pediatric GH Deficiency (iPGHD) from the Interim Analysis Data of the OraGrowtH212 Trial
  • Poster Presentation - Baseline Demographics of the OraGrowtH210 Trial Studying LUM-201 in Idiopathic Pediatric Growth Hormone Deficiency (iPGHD) Interim Analysis Data
    
    
• Formulation patent for LUM-201 filed November 2022. In November 2022, we filed a patent application PCT/US22/050700 titled “Compactable Oral Formulations of Ibutamoren.” The application is currently pending and contains claims directed to certain improved formulations we intend to utilize in our Phase 3 trial and ultimately commercialize. If granted, this patent would provide composition of matter protection through November 2042 for the commercialized version of LUM-201.

About Lumos Pharma’s Clinical Trials
Phase 2 OraGrowtH210 Trial of Oral LUM-201 in PGHD

The OraGrowtH210 Trial is a multi-site, global trial evaluating orally administered LUM-201 at three dose levels (0.8, 1.6, 3.2 mg/kg/day) against a standard dose of injectable rhGH in approximately 80 subjects diagnosed with idiopathic (moderate) PGHD, which is less severe than organic PGHD. The objective of this trial is to identify the optimal dose of LUM-201 to be used in a Phase 3 registration trial, based on annualized height velocity from a 6-month dataset, and to prospectively confirm the preliminary validation of our Predictive Enrichment Marker (PEM) strategy. The complete set of 6-month, primary outcome data for 82 subjects is anticipated in the fourth quarter of 2023. Subjects will be dosed for a total of 24 months.

OraGrowtH212 Trial Evaluating PK/PD and Pulsatility of Oral LUM-201 in PGHD

The OraGrowtH212 Trial is a single site, open-label trial evaluating the pharmacokinetic (PK) and pharmacodynamic (PD) effects of oral LUM-201 in up to 24 PGHD subjects at two dose levels, 1.6 and 3.2 mg/kg/day. The primary objective of the OraGrowtH212 Trial is to confirm prior clinical data demonstrating the amplified pulsatile release of endogenous growth hormone from LUM-201 therapy, contributes to its efficacy in PGHD. The primary endpoint for this trial is 6 months of PK/PD (pulsatility) and height velocity data in the randomized subjects. Subjects will be allowed to remain on treatment until they reach a bone age of 14 for females and 16 for males reflecting near-adult height. Primary data readout in 22 subjects is anticipated in the fourth quarter of 2023.

Switch Study, OraGrowtH213 Trial, Evaluating LUM-201 in OraGrowtH210 Subjects Previously on rhGH

The OraGrowtH213 Trial is an open-label, multi-center, Phase 2 study evaluating the growth effects and safety of LUM-201 following 12 months of daily rhGH in up to 20 idiopathic PGHD patients who have completed the OraGrowtH210 Trial. Subjects will be administered LUM-201 at a dose level of 3.2 mg/kg/day for up to 12 months.

Lumos Pharma Collaboration with Massachusetts General Hospital Evaluating LUM-201 in NAFLD

Lumos Pharma has entered a collaboration with Massachusetts General Hospital (MGH) to evaluate LUM-201 in patients with nonalcoholic fatty liver disease (NAFLD). GH is a critical stimulator of lipolysis, and shows anti-inflammatory effects, and preclinical data suggest that amplifying GH secretion has the potential to reduce hepatic steatosis and prevent NAFLD progression. Interestingly, enhancing the natural pulsatile release of GH has been shown clinically in short-term studies to be more efficacious in inducing lipolysis than continuous infusions of GH. This MGH investigator-initiated trial is a single-site, 6-month, open-label pilot study of daily oral LUM-201 in adults with NAFLD. The trial will evaluate a dose of 25 mg/day of LUM-201 in 10 subjects with NAFLD and relative IGF-1 deficiency. The primary endpoints will be to determine the reduction in liver lipid content, inflammation, and fibrosis in these subjects administered LUM-201 compared to each subject’s baseline.
