AUSTIN, Texas, May 10, 2022 (GLOBE NEWSWIRE) -- Lumos Pharma, Inc. (NASDAQ:LUMO), a clinical-stage biopharmaceutical company focused on therapeutics for rare diseases, today announced financial results for the quarter ended March 31, 2022 and clinical development updates.

"To date, 2022 has been a productive period for Lumos, with encouraging enrollment trends in both of our OraGrowtH210 and OraGrowtH212 trials evaluating orally administered LUM-201 in pediatric growth hormone disease (PGHD) and our announcement of planned interim data analyses by the end of this year," said Rick Hawkins, Chairman and CEO of Lumos Pharma. "Other notable events included a journal publication of a peer-reviewed article supporting LUM-201 as a potent GH secretagogue, and the removal of partial clinical hold for treatment past 12 months. With momentum building in our LUM-201 program for PGHD, we are also honored to collaborate with Mass General on an investigator-initiated trial evaluating LUM-201 in NAFLD. We continue to execute on our clinical programs and look forward to interim data from our OraGrowtH Trials later this year."

Recent Highlights

Phase 2 OraGrowtH210 Trial exceeds 50% randomization – Interim analyses for OraGrowtH210 and PK/PD OraGrowtH212 Trials by end of 2022. OraGrowtH210 has now exceeded the 50% randomization milestone, and subject enrollment in both the OraGrowtH210 and OraGrowtH212 Trials is progressing sufficiently for us to confirm our plan to conduct interim analyses of data from both trials by the end of 2022. We believe the interim data should provide an early indication of efficacy and safety of oral LUM-201 versus standard of care daily rhGH injections in PGHD. We continue to anticipate primary outcome data on 80 subjects from our OraGrowtH210 Trial in the second half of 2023.
FDA lifts partial clinical hold on treatment beyond 12 months after review of preliminary data from OraGrowtH trials. In July 2021, we announced that the U.S. Food & Drug Administration (FDA) had restricted treatment with LUM-201 to no more than 12 months. Based on a review of preliminary safety and efficacy data from both OraGrowtH trials in progress the FDA has lifted the partial hold and will now permit treatment with LUM-201 beyond twelve months. As a result, the OraGrowtH210 Trial will be extended to 24 months to allow subjects to continue LUM-201 therapy uninterrupted. Additionally, we plan to extend the duration of the OraGrowtH212 Trial.
Peer-reviewed journal publication demonstrates LUM-201's potency as GH secretagogue. A peer-reviewed article illustrating LUM-201's greater potency over standard growth hormone secretagogues was published March 30, 2022, in the journal, Hormone Research in Paediatrics. The article, co-authored by George Bright, MD and Michael Thorner, MB, BS, entitled "A GH Secretagogue Receptor Agonist (LUM-201) Elicits Greater GH Responses than Standard GH Secretagogues in Subjects of a Pediatric GH Deficiency Trial," further supports prior data suggesting LUM-201's therapeutic potential when administered to pediatric subjects with idiopathic growth hormone deficiency.
Lumos Pharma collaborates with Massachusetts General to evaluate LUM-201 in NAFLD. The Company 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-initiated pilot study. While we remain focused on our core LUM-201 program in PGHD, the Company is pleased to support Mass General's exploration of LUM-201's potential in this indication, a condition estimated to be prevalent in approximately 25% of adults worldwide. NAFLD can often advance to the more serious liver disease non-alcoholic steatohepatitis (NASH) with fibrosis, and NASH-associated liver failure is one of the leading causes of liver transplants in the United States.

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 interim analysis will evaluate the safety and annualized height velocity of the three dose levels of LUM-201 against a standard dose of injectable recombinant human growth hormone (rhGH) in a minimum of 40 subjects at six months on therapy. The complete set of 6-month, primary outcome data for 80 patients is anticipated in the second half 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 objective of the OraGrowtH212 Trial is to confirm prior clinical data demonstrating the amplified pulsatile release of endogenous growth hormone from LUM-201 therapy differentially contributes to its efficacy in PGHD. The primary endpoint for this trial is six months of PK/PD and height velocity data in up to 24 subjects. Subjects will be dosed for a total of 12 months, with a plan to extend the duration of the trial. Interim data on a minimum of 10 subjects is anticipated by the end of 2022.

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 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 potentially fibrosis in these subjects administered LUM-201 compared to historical placebo-treated controls.
