"With the interim readout from our OraGrowtH210 and OraGrowtH212 trials announced today, we look forward to continuing to advance our clinical program and planning for our pivotal Phase 3 trial for potentially the first oral therapeutic for PGHD," said Rick Hawkins, Chairman and CEO of Lumos Pharma. "In the 1.6 mg/kg/day LUM-201 arm in the OraGrowtH210 study, we observed mean annualized height velocity of 8.6 cm/yr, in line with 8.3 cm/yr expected based on growth on rhGH for moderate PGHD subjects observed in multiple large datasets. We look forward to building on this initial data and expect to report primary outcome results from both OraGrowtH trials in the second half of 2023. Additionally, our collaboration with Mass General on an investigator sponsored trial evaluating LUM-201 in NAFLD continues, and the trial has dosed its first subject and continues to enroll."
Recent Highlights
Interim analyses for Phase 2 OraGrowtH210 and PK/PD OraGrowtH212 Trials met expectations. Interim analysis for Phase 2 OraGrowtH210 Trial demonstrated that the 1.6 mg/kg/day LUM-201 dose produced a mean annualized height velocity (AHV) of 8.6 cm/yr at six months on treatment for moderate (idiopathic) PGHD subjects. This met the expected AHV of 8.3 cm/yr observed for moderate naive-to-treatment PGHD subjects on rhGH at 12 months observed in Eli Lilly’s large Phase 4 GeNeSIS1 dataset and comparable findings from other large historical datasets.2,3 In addition, interim data from both OraGrowtH210 and OraGrowtH212 Trials demonstrated durability of LUM-201 response out to 12 months. The rhGH control arm produced an AHV of 11.05 cm at six months, an unexpected growth response in this moderate PGHD population. This higher than anticipated AHV in the rhGH arm was likely due both to the presence of a growth outlier and to imbalances in several baseline characteristics for this arm that are well documented in the published literature as predictors of greater growth response to rhGH. We believe LUM-201 will demonstrate a favorable safety profile as our interim data from both OraGrowtH trials show comparable safety and tolerability to the rhGH subjects in the trials. Interim data from both OraGrowtH trials support the selection of the 1.6 mg/kg/day LUM-201 dose for a pivotal Phase 3 trial.

Enrollment for the OraGrowtH210 Trial is now at ~80%. The primary outcome data on 80 subjects from OraGrowtH210 Trial and up to 24 subjects from our OraGrowtH212 Trial continues to be anticipated in the second half of 2023.
Enrollment Initiated in Massachusetts General Investigator-Initiated Trial evaluating LUM-201 in NAFLD. 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. Enrollment in the trial has begun, and the first subject has been dosed. While we remain focused on our core LUM-201 program in PGHD, we are 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.

Financial Results for the Quarter Ended September 30, 2022
Cash Position – Lumos Pharma ended the quarter on September 30, 2022 with cash and cash equivalents totaling $73.7 million compared to $94.8 million on December 31, 2021. The Company expects cash use of approximately $8.5 to $9.5 million in the fourth quarter of 2022. Cash on hand as of September 30, 2022 is expected to support operations into the second quarter of 2024, inclusive of the primary outcome data readout from OraGrowtH210 and OraGrowtH212 Trials anticipated in the second half of 2023.
R&D Expenses – Research and development expenses were $4.1 million for the quarter ended September 30, 2022, compared to $4.1 million for the same period in 2021, primarily due to an increase of $0.3 million in personnel-related expenses and $0.1 million in consulting expenses, offset by a decrease of $0.4 million in clinical trial and contract manufacturing expenses.
G&A Expenses – General and administrative expenses were $3.9 million for the quarter ended September 30, 2022, an increase compared to $3.4 million for the same period in 2021, primarily due to increases of $0.3 million in royalty expenses, $0.2 million in consulting expenses and $0.1 million in travel-related expenses, offset by a decrease of $0.1 million in other miscellaneous expenses.

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 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 80 subjects is anticipated in the second half 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 up to 24 subjects. Subjects will be allowed to remain on treatment until they reach their near-adult height. Primary data readout in up to 24 subjects is anticipated in the second half 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 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 subjects 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 ten 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.
