Lumos Pharma Reports First Quarter 2023 Financial Results, Provides Clinical Updates

-- Patient Enrollment Completed in both Phase 2 OraGrowtH Trials --
-- Primary Outcome Data for both OraGrowtH Trials Expected 4Q 2023 --
-- Interim Data from OraGrowtH Trials Accepted for Presentation at PES 2023 –
-- Conference Call Scheduled for Today at 4:30pm ET --

AUSTIN, TX, May 3, 2023 – Lumos Pharma, Inc. (NASDAQ:LUMO), a biopharmaceutical company advancing an oral therapeutic candidate for Pediatric Growth Hormone Deficiency (PGHD) through Phase 2 clinical trials, today announced financial results for the quarter ended March 31, 2023.

“With both our Phase 2 OraGrowtH210 and OraGrowtH212 Trials evaluating oral LUM-201 in moderate (idiopathic) PGHD fully enrolled, we look forward to announcing top line results in the fourth quarter of 2023,” said Rick Hawkins, Chair and CEO of Lumos Pharma. “We were also pleased to see updated interim data from these two OraGrowtH Trials highlighted at the 2023 IMPE meeting and accepted for presentation at the upcoming 2023 PES annual meeting. These data reinforce our prediction from our interim analysis that the 1.6 mg/kg dose is on track to meet growth expectations in moderate PGHD patients based on historical database averages. The presented data further demonstrate that LUM-201 possesses both a favorable safety profile and a natural, endogenous mechanism of action with potency to stimulate meaningful growth in this idiopathic PGHD patient population.”

Recent Highlights

Interim Data from OraGrowtH210 and OraGrowtH212 Trials accepted for presentation at annual Pediatric Endocrine Society (PES) Meeting (May 5-8)
An oral presentation on OraGrowtH210 Trial interim data will be given by Andrew Dauber, MD, Chief of Endocrinology, Children’s National Hospital
A poster presentation on OraGrowtH212 Trial interim data by Fernando Cassorla, MD, Chief of Pediatric Endocrinology, University of Chile, will be presented by David B. Karpf, MD, Chief Medical Officer, Lumos Pharma

Additional OraGrowtH212 Trial data and interim OraGrowtH210 Trial data were presented at the 2023 International Meeting of Pediatric Endocrinology (IMPE) (Mar 4-7)
An oral presentation by Fernando Cassorla, MD, on OraGrowtH212 data further supported the pulsatile MOA of LUM-201 and highlighted growth stimulated by oral LUM-201 in PEM-positive PGHD subjects
OraGrowtH210 interim data were presented in a poster by Alison Lunsford, MD, Assistant Professor, Texas Tech Physicians of Amarillo, demonstrating the favorable safety and tolerability profile of LUM-201 and that the 1.6 mg/kg/day LUM-201 dose demonstrated 8.6 cm/yr 6-month annualized height velocity in line with historical growth for moderate idiopathic PGHD patients treated with injectable standard of care (rhGH)

OraGrowtH210 and OraGrowtH212 Trials are fully enrolled as announced on February 28, 2023
Between interim and full enrollment, age and other baseline characteristics for OraGrowtH210 subjects converged across 1.6mg LUM-201 and rhGH cohorts as predicted given the stratification of the trial by age and the balancing effect of the additional subjects included at full enrollment
Primary outcome data from OraGrowtH210 and OraGrowtH212 Trials are expected Q4 2023

Financial Results for the Quarter Ended March 31, 2023

Cash Position – Lumos Pharma ended the quarter on March 31, 2023 with cash, cash equivalents and short-term investments totaling $58.0 million compared to $67.4 million on December 31, 2022. The Company expects an average cash use of approximately $9.5 to $10.5 million per quarter through 2023. Cash on hand as of March 31, 2023 is expected to support operations into the third quarter of 2024, well beyond top line results from our Phase 2 OraGrowtH210 and OraGrowtH212 Trials expected in the fourth quarter of 2023.

R&D Expenses – Research and development expenses for the quarter ended March 31, 2023 were $4.4 million, an increase of approximately $0.1 million compared to the same period in 2022.

G&A Expenses – General and administrative expenses for the quarter ended March 31, 2023 were $4.4 million, an increase of approximately $0.7 million over the same period in 2022, primarily due to increases of $0.4 million in licensing expenses, $0.1 million in personnel-related expenses and $0.2 million in travel expenses.

Net Loss – The net loss for the quarter ended March 31, 2023 was $7.3 million compared to a net loss of $7.7 million for the same period in 2022.

Lumos Pharma had 8,183,296 shares outstanding as of March 31, 2023.

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 0.34 mcg/kg/day dose of injectable rhGH in 82 subjects diagnosed with idiopathic (moderate) PGHD, all of whom are also Predictive Enrichment Marker (PEM) positive. 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 with durability data of up to 24 months, and to prospectively confirm the utility of our PEM strategy. The complete set of 6-month, primary outcome data for up to 82 subjects is anticipated in the fourth quarter of 2023.

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 22 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 that the restoration of natural 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


Exhibit 99.1

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 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 and inflammation, and impact on fibrosis in these subjects administered oral LUM-201 compared to each subject’s baseline.
