-- Phase 2 Data for Potentially the First Oral Therapeutic for PGHD Met All Primary and Secondary Endpoints with Supportive Evidence to Advance to Phase 3 – -- OraGrowtH210 Trial Results Show LUM-201 Dose of 1.6 mg/kg Achieves AHVs of 8.2 cm/yr at 6 Months and 8.0 cm/yr at 12 Months, Consistent with Historical Growth Rates for Moderate PGHD Population – -- OraGrowtH212 Data Confirm Unique Pulsatile Mechanism of Action of LUM-201and Demonstrate Closer to Normal Physiological Growth Hormone Levels and Normalized IGF-1 Levels – -- Cash of $42.7 Million at End of Q3 2023 Provides Runway through Third Quarter 2024 -- AUSTIN, Texas, Nov. 07, 2023 (GLOBE NEWSWIRE) -- Lumos Pharma, Inc. (NASDAQ:LUMO), a clinical-stage biopharmaceutical company focused on therapeutics for rare diseases, today announced that topline results met primary and secondary endpoints for its Phase 2 Dose-Finding OraGrowtH210 Trial and Phase 2 Pharmacokinetic/Pharmacodynamic (PK/PD) OraGrowtH212 Trial evaluating oral LUM-201 for subjects with moderate pediatric growth hormone deficiency (PGHD) who screened PEM-positive utilizing Lumos Pharma’s predictive enrichment marker (PEM) strategy. Lumos also announced its financial results for the quarter ended September 30, 2023. “With the end of Phase 2 readout from our OraGrowtH210 and OraGrowtH212 trials announced today, we are thrilled that these data support advancing our clinical program towards a pivotal Phase 3 trial for potentially the first oral therapeutic for moderate PGHD,” said Rick Hawkins, Chairman and CEO of Lumos Pharma. “Data confirm the optimal dose is 1.6 mg/kg/day LUM-201 to advance to Phase 3, and preliminary data show durability out to 24 months of treatment. Additionally, the OraGrowtH212 data reaffirms our confidence in our oral compound’s unique mechanism of action, the importance of the natural, pulsatile release of growth hormone, and its impact on restoring growth.” Recent Highlights Phase 2 OraGrowtH210 and PK/PD OraGrowtH212 Trials met all primary and secondary endpoints. Data from the topline Phase 2 OraGrowtH210 Trial demonstrated that the 1.6 mg/kg/day LUM-201 dose produced a mean annualized height velocity (AHV) of 8.2 cm/yr at six months on treatment for moderate PGHD subjects, in line with historical data in moderate PGHD patients1,2,3,4. Additionally, at twelve months on treatment, a durable effect was also observed with LUM-201 achieving AHV of 8.0 cm/yr at the 1.6 mg/kg dose, within the targeted 2 cm/yr margin of the comparator injectable rhGH arm. Data also provided preliminary validation of the PEM strategy, with prespecified primary and secondary outcomes met, de-risking our patient selection for our Phase 3 program. Data from the OraGrowtH212 Trial confirmed that LUM-201’s unique pulsatile mechanism produces an increase in the growth rates by restoring growth hormone secretion and IGF-1 to within normal ranges. The safety profile for LUM-201 remained clean throughout both Phase 2 trials, with no safety concerns identified in either of our Phase 2 trials conducted thus far.

OraGrowtH212 Trial Data Presented at the 2023 annual meeting of the European Society for Paediatric Endocrinology. An oral presentation of the deconvolution analysis of growth hormone (GH) concentration sampled over 12 hours at baseline and after 6 months of therapy with daily oral LUM-201 illustrated how treatment with LUM-201 increases AHV, total GH secretion, and serum IGF-1 and IGFBP3 for individuals with moderate PGHD. Measured at 6 months compared to baseline, data showed a 60% increase in GH secretion to a level comparable to established values in normal healthy children and a 62% increase in AHV.Independent Panel of Renowned Pediatric Endocrinologists Discussed PGHD and Therapeutic Landscape. On September 5, 2023, a panel of five pediatric endocrinologists participated in a webinar where they discussed the benefits that the oral therapeutic LUM-201 candidate may provide compared to current injectable therapeutic options.

About Lumos Pharma’s Clinical TrialsPhase 2 OraGrowtH210 Trial Design 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) compared to daily injectable recombinant human growth hormone (rhGH) 34 µg/kg/day in 82 subjects diagnosed with moderate PGHD. The trial population was enriched for subjects responsive to LUM-201 during screening by applying the specific PEM cutoffs of a baseline IGF-1 value > 30 ng/ml and a peak growth hormone value of ≥ 5 ng/ml after administering a single dose of 0.8 mg/kg of LUM-201 to treatment-naïve PGHD patients. The study was not designed to evaluate efficacy and demonstrate non-inferiority to daily GH. OraGrowtH212 Trial Design 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 treatment-naïve PGHD subjects at two dose levels, 1.6 and 3.2 mg/kg/day. Every subject in the OraGrowtH212 Trial was PEM-positive and, therefore, enriched for responsiveness to LUM-201. Switch Study, OraGrowtH213 Trial, Evaluating LUM-201 in OraGrowtH210 Subjects Previously on rhGH The OraGrowtH213 Trial is an open-label, multi-center, Phase 2 trial 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.

(NASDAQ:LUMO) today announced that topline results from its Phase 2 OraGrowtH210 dose-finding trial and its Phase 2 OraGrowtH212 Pharmacokinetic/Pharmacodynamic (PK/PD) trial met all primary and secondary endpoints. Data from the OraGrowtH210 Trial demonstrated annualized height velocity (AHV) on the 1.6 mg/kg dose of orally administered LUM-201 of 8.2 cm/yr at six months and 8.0 cm/yr at 12 months on treatment,* in line with historical data in moderate pediatric growth hormone deficiency (PGHD) patients and within the targeted 2 cm/yr margin of the comparator injectable recombinant growth hormone (rhGH) arm. Data also provided preliminary validation of the predictive enrichment marker (PEM) strategy, with prespecified primary and secondary outcomes met, de-risking our patient selection for our Phase 3 program. Data from the OraGrowtH212 Trial confirmed that LUM-201’s unique pulsatile mechanism produces an increase in growth rates while restoring growth hormone secretion and IGF-1 to within normal ranges †, with levels substantially below those produced by exogenous injectable rhGH.†† Additionally, data from a small subset of 10 subjects combined 1.6 and 3.2 mg/kg dosage of LUM-201 in both OraGrowtH210 and OraGrowtH212 trials demonstrated the sustained effectiveness of AHV up to 24 months. Furthermore, the safety profile for LUM-201 remained clean throughout both Phase 2 studies, with no safety concerns identified in either of our Phase 2 trials conducted thus far. “Results from our OraGrowtH trials have provided us with clear proof of concept that oral LUM-201 has the potential to serve as a viable alternative to injectable therapies in moderately growth hormone deficient patients. Our data indicates that LUM-201 can enhance AHVs in line with established standards for moderate PGHD patients undergoing rhGH therapy, demonstrating a robust and durable response,” said Rick Hawkins, Chairman and CEO of Lumos Pharma. “We look forward to discussing these data and finalizing our plans for a Phase 3 pivotal trial with the FDA in our end of Phase 2 meeting anticipated in the first half of 2024.” Renowned pediatric endocrinologist Dr. Ron Rosenfeld, who also serves as the Chairman of our Clinical and Scientific Advisory Board, provided insight on the data, stating, "These findings not only align with historical growth expectations on therapy but also underscore the distinct advantage of LUM-201's unique pulsatile mechanism. Demonstrating the ability to achieve expected growth with oral LUM-201 while exposing patients to only 20% of the growth hormone compared to daily rhGH injections is a significant scientific breakthrough that has the potential to revolutionize the approach to treating children with moderate growth hormone deficiency." OraGrowtH210 Topline Results HighlightsThe OraGrowtH210 trial met its primary objective, with 6-month AHV data of 8.2 cm/yr supporting the 1.6 mg/kg as the optimal dose for a Phase 3 clinical trial.* The 6-month and 12-month AHV on 1.6 mg/kg/day met expectations for growth and were within the targeted 2.0 cm/yr margin for non-inferiority against injectable rhGH cohort. ANCOVA Model Terms: treatment, Age at dose 1, Sex, Baseline HT SDS, Baseline BMI SDS, Baseline IGF-1 SDS, LUM-201 PEM, Baseline BA Delay, HT SDS-MPH SDS Bars represent Least Squares Mean (LSM), Error bars represent the Standard Error of LSM Dosage at 1.6 mg/kg demonstrates highest LUM-201 AHV at six months and 12 months1.7 cm/yr difference between 1.6 mg/kg LUM-201 dose and rhGH comparator arm at 12 months falls within historical non-inferiority Phase 3 marginsLUM-201 AHVs align with historical growth rates of rhGH in patient populations with similar characteristics.12-month AHV data available for 50/81 subjects: Growth rates durable at 12 months The mean AHVs at 6 months and 12 months observed in the 1.6 mg/kg dose LUM-201 arm were 8.2 cm/yr and 8.0 cm/yr, respectively. These AHVs were in line with the Company’s expectations for 8.3-8.6 cm/yr AHV observed after 12 months of rhGH treatment in a moderate PGHD patient population.1,2,3 The higher than anticipated AHV seen in this moderate PGHD population treated in the rhGH control arm of the OraGrowtH210 Trial was inconsistent with multiple historical trials which predicted growth in the 8.3-8.6 cm/yr range for moderate PGHD1-4. This distinctive growth pattern observed in the daily GH arm of this study is likely due to a higher dosage and the presence of outliers. We anticipate that in a larger, more statistically robust Phase 3 trial, the AHV associated with rhGH treatment will align more closely with historical values for the moderate patient population. The OraGrowtH210 Trial met the prespecified percent responder enrichment providing preliminary validation of the PEM strategy. Additionally, we have achieved a 100% success rate in meeting the predetermined outcome for positive PEM specification classification reproducibility. OraGrowtH212 Topline Results HighlightsThe topline results from the OraGrowtH212 Trial reveal that LUM-201 achieved an expected AHV with only 20% of the growth hormone (GH) concentration observed using injectable rhGH. This outcome was achieved through LUM-201's natural pulsatile mechanism, promoting growth in moderate PGHD subjects that align with historical norms. Notably, LUM-201 raised circulating GH to levels closer to normal physiological ranges, whereas treatment with injectable rhGH has been shown to elevate GH levels to four to five times that of typical healthy children. Furthermore, it's important to highlight that during the first 12 months of LUM-201 treatment, no IGF-1 values exceeded 2 standard deviations from the mean. Combined 24-Month Data from OraGrowtH210 and OraGrowtH212 Trials Eighteen and 24-month growth data were available for 10 subjects from the OraGrowtH210 and OraGrowtH212 Trials who met AHV criteria per protocol at 12 months.Combined data from the 1.6 mg/kg and 3.2 mg/kg cohorts of both trials demonstrate sustained AHVs from 12 to 24 months without a considerable decline in growth velocity compared to the previously reported ~20% decline in AHV on rhGH from 12 to 24 months observed in the Pfizer Phase 4 KIGS dataset.3 Safety & Tolerability HighlightsThe topline results from both the OraGrowtH210 and OraGrowtH212 trials have shown a clean safety record, characterized by an absence of treatment-related Serious Adverse Events (SAEs), no instances of participants discontinuing treatment due to adverse events (AEs), and the absence of any significant safety concerns in various parameters such as laboratory values, adverse event data, or in electrocardiogram (ECG) readings. † Zadik et al Horm Res 1992†† Adapted from data in Albertsson-Wikland et al JCEM 1994; 24h exposures listed reflect absorbance/bioavailability of ~60% of the administered dose, * For all OraGrowtH Trial AHV values, ANCOVA Model Terms: treatment, Age at dose 1, Sex, Baseline HT SDS, Baseline BMI SDS, Baseline IGF-1 SDS, LUM-201 PEM, Baseline BA Delay, for graphs HT SDS-MPH SDS Bars represent Least Squares Mean (LSM), Error bars represent the Standard Error of LSM1 Blum et al JES 2021, 2 Lechuga-Sancho et al JPEM 2009, 3 Ranke et al JCEM 2010, 4 Bright et al JES 2021 Conference Call and Webcast Details Date: November 8, 2023Time: 8:30 AM ET Dial-in: 1-877-407-9716 or 1-201-493-6779 (international) Conference ID: 13742617Or Dial-in registration (Available 15 minutes prior to scheduled start time): https://callme.viavid.com/viavid/?callme=true&passcode=13742617&h=true&info=company-email&r=true&B=6Webcast link: https://viavid.webcasts.com/starthere.jsp?ei=1642841&tp_key=d9efda8a69 Slides are available on the Lumos Pharma website in the “Investors & Media” section under “Events and Presentations” link: https://investors.lumos-pharma.com/events-presentations.

OraGrowtH210 Trial DesignThe OraGrowtH210 Trial is a global, multi-site study that assesses the effects of orally administered LUM-201 at three different dose levels (0.8, 1.6, 3.2 mg/kg/day) in comparison to daily injections of recombinant human growth hormone (rhGH) at a dose of 34 µg/kg/day. This trial involves 82 participants diagnosed with moderate Pediatric Growth Hormone Deficiency (PGHD). To enrich the trial population with individuals likely to respond to LUM-201, specific PEM criteria were applied during the screening process. These criteria included having a baseline IGF-1 value above 30 ng/ml and achieving a peak growth hormone value of 5 ng/ml or higher after administering a single 0.8 mg/kg dose of LUM-201 to treatment-naïve PGHD patients. It is important to note that the primary purpose of this study was not to establish efficacy or demonstrate non-inferiority compared to daily GH treatment. OraGrowtH212 Trial DesignThe OraGrowtH212 Trial is a single-site, open-label study designed to assess the pharmacokinetic (PK) and pharmacodynamic (PD) impacts of oral LUM-201. This trial includes up to 24 individuals with no prior treatment for Pediatric Growth Hormone Deficiency (PGHD), who are administered LUM-201 at two different dosage levels, specifically 1.6 and 3.2 mg/kg/day. Every participant in the OraGrowtH212 Trial met the criteria for Patient PEM positivity, ensuring their potential responsiveness to LUM-201.

You should not rely on any of these forward-looking statements and, to help you make your own risk determinations, we have provided an extensive discussion of risks that could cause actual results to differ materially from our forward-looking statements including risks related to the continued analysis of data from our LUM-201 Trials, the timing and outcome of our future interactions with regulatory authorities including our end of Phase 2 meeting with the FDA, the timing and ability of Lumos to raise additional equity capital as needed to fund our Phase 3 Trial, our ability to project future cash utilization and reserves needed for contingent future liabilities and business operations, the ability to structure our Phase 3 trial in an effective and timely manner, the ability to successfully develop our product candidate, the effects of pandemics, other widespread health problems or military conflicts including the Ukraine-Russia conflict and the Middle East conflict and other risks that could cause actual results to differ materially from those matters expressed in or implied by such forward-looking statements including information in the "Risk Factors" section and elsewhere in Lumos Pharma’s Quarterly Report on Form 10-Q for the period ended June 30, 2023, as well as other reports filed with the SEC including our subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K.
