Lumos Pharma Completes Patient Enrollment in Two Phase 2 OraGrowtH Trials Evaluating Oral LUM-201 in Moderate Idiopathic PGHD

Phase 2 OraGrowtH210 and Phase 2 PK/PD OraGrowtH212 Trials Are Fully Enrolled

Primary Outcome Data for Both OraGrowtH Trials Expected 4Q 2023

AUSTIN, Texas, Feb. 28, 2023 (GLOBE NEWSWIRE) -- Lumos Pharma, Inc. (NASDAQ:LUMO), a biopharmaceutical company advancing an oral therapeutic candidate for Pediatric Growth Hormone Deficiency (PGHD) through Phase 2 clinical trials, announced today that the last subjects have been enrolled and randomized in the Company’s OraGrowtH210 and OraGrowtH212 trials evaluating LUM-201 for the treatment of moderate idiopathic PGHD. The Company now expects data on 82 subjects in the OraGrowtH210 Trial and 22 subjects in the PK/PD OraGrowtH212 Trial.

“We are very pleased to have reached these important milestones, which will allow us to complete our OraGrowtH trials and announce top line results in the fourth quarter of 2023,” said Rick Hawkins, Chairman and CEO of Lumos Pharma. “The interim data we announced in November showed that in the 1.6 mg/kg/day LUM-201 arm in the OraGrowtH210 study, mean annualized height velocity of 8.6 cm/yr was observed, in line with 8.3 – 8.6 cm/yr expected based on growth on rhGH for moderate PGHD subjects consistently observed in multiple large datasets. We look forward to building on these initial data, reporting primary outcome results, and continuing to advance our clinical program and planning for our pivotal Phase 3 trial for potentially the first oral therapeutic for PGHD.”

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. 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 utility of our Predictive Enrichment Marker (PEM) strategy. The interim analysis demonstrated that LUM-201 in the 1.6 mg/kg/day arm met expectations at six months of treatment with an AHV of 8.6 cm as compared to the AHV of 8.3 cm observed in the PEM-positive moderate naive-to-treatment PGHD subjects for 12 months on rhGH as derived from the large 20-year Phase 4 Eli Lilly GeNeSIS database. The complete set of six-month, primary outcome data for 82 subjects is anticipated in the fourth quarter of 2023. Subjects will be treated for up to 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 six months of PK/PD (pulsatility) and height velocity data in 22 subjects. Subjects will be allowed to remain on treatment until they reach their 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 subjects who have completed the OraGrowtH210 Trial. Subjects are administered LUM-201 at a dose level of 3.2 mg/kg/day for up to 12 months. This trial is currently enrolling subjects.
