Lumos Pharma Announces Topline Data from Phase 2 OraGrowtH210 and OraGrowtH212 Trials of LUM-201 in PGHD Met All Primary and Secondary Endpoints
AUSTIN, Texas, Nov. 07, 2023 (GLOBE NEWSWIRE) -- Lumos Pharma, Inc. (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.
- 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.
- The 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.
- 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.
- Every participant in the OraGrowtH212 Trial met the criteria for Patient PEM positivity, ensuring their potential responsiveness to LUM-201.
