Outcome from End-of-Phase 2 Meeting Supportive of a Placebo-Controlled Phase 3 Trial

Company to Host Conference Call May 15, 2024, at 8:30AM ET

AUSTIN, Texas, May 14, 2024 (GLOBE NEWSWIRE) -- Lumos Pharma, Inc. (NASDAQ:LUMO), a clinical stage biopharmaceutical company focused on therapeutics for rare diseases, today announced the outcome from its End-of-Phase 2 meeting with the FDA, provided a clinical programs update, and reported financial results for the quarter ended March 31, 2024.

"We are pleased to announce that, earlier this quarter, we had a very productive End-of-Phase 2 meeting with the FDA," said Rick Hawkins, Chairman and CEO of Lumos Pharma. "In this review, the FDA recognized LUM-201's unique mechanism as a growth hormone secretagogue and acknowledged the use of a placebo-controlled clinical trial design as an appropriate option for a LUM-201 Phase 3 trial. Based on the FDA’s feedback, we plan to move forward with a proposal for a single Phase 3 study that will be a double-blinded, placebo-controlled clinical trial with a 2:1 randomization in approximately 150 patients. We expect to finalize design details with the FDA in the third quarter and to be in position to initiate this trial before the end of this year.

"In addition to our encouraging engagement with the FDA, we are also very pleased to share updated data from our Phase 2 OraGrowtH trials. These data continue to show that LUM-201 produces a significant increase in growth from baseline in annualized height velocity (AHV) at 6 and 12 months in per protocol analysis. Combined data also suggest durable benefit out to 24 months.

"We believe these developments have positioned us to advance LUM-201 toward both a Phase 3 registrational trial and potential approval of LUM-201 as the first oral therapeutic for moderate pediatric growth hormone deficiency," Rick Hawkins concluded.  

Recent Highlights

• End of Phase 2 Meeting Held with FDA
  • FDA indicated that a placebo-controlled trial design is an appropriate option for a Phase 3 trial for LUM-201. We believe this reflects FDA’s recognition of unique qualities of LUM-201’s mechanism of action as a growth hormone secretagogue.
  • Proposal for a Phase 3 trial to include a 12-month double-blinded, placebo-controlled design with 2:1 randomization, ~150 patients with the placebo-controlled portion of the study lasting six months, which we believe will improve the likelihood of success when compared to a non-inferiority study.
  • Planning is ongoing, and the Company expects to initiate a Phase 3 trial of LUM-201 in Q4 2024, subject to FDA approval.
• Updated LUM-201 Data from Combined OraGrowtH210 and OraGrowtH212 Trials
  • Additional data continue to show durable LUM-201 treatment effect to 12 and 24 months.
  • Full 12-month data from OraGrowtH210 demonstrated LUM-201 produces significant increase in growth from baseline with AHVs of 8.2 cm/yr (N=22) and 7.6 cm/yr (N=21) at 6 and 12 months, respectively, at the 1.6 mg/kg dose vs. 4.7 cm/yr baseline growth (N=13).*
  • Full 12-month data from OraGrowtH210 continued to show durable effect to 12 months for all LUM-201 cohorts and 1.6 mg/kg/day as optimal dose to advance to Phase 3.
  • Updated combined data from OraGrowtH210 and OraGrowtH212 trials continued to demonstrate LUM-201 AHV durable to 24 months with per protocol-24M (N=12) AHV of 8.1 cm/yr and 7.3 cm/yr at 12 and 24 months, respectively.
  • More moderate year-2 decline in AHV of 9.9% for LUM-201 compared to year-2 decline in AHV of 19.7% observed in historical rhGH benchmarks likely due to LUM-201 restoration of GH and IGF-1 to normal levels via amplification of physiologic pulsatile secretion of growth hormone within the natural endocrine feedback loop.
  • Investigational safety profile continues to be favorable.
• Data from Phase 2 OraGrowtH210 and OraGrowtH212 Trials Presented at Medical Meetings in US and Europe
  • Pediatric Endocrinology Society (PES)
  • 10th International Congress of the Growth Hormone Research Society (GRS)
  • European Congress of Endocrinology (ECE)
  • Data presented at these medical conferences demonstrate that, by augmenting the natural pulsatile secretion of growth hormone, LUM-201 produces comparable growth to injectable rhGH with significantly less exposure to circulating growth hormone.
• Additional Data from Phase 2 OraGrowtH Trials to be Presented in Q2 2024
  • Full 12-Month OraGrowtH212 data, additional analyses of OraGrowtH210 data, and updated combined 24-month data to be presented in Q2 2024
  • Two abstracts accepted for poster presentation at the Endocrine Society (ENDO) Annual Meeting
    

*Baseline AHV data were not required for enrollment; baseline data available for N=13 subjects.
