Updated Phase 2 OraGrowtH Data Presented at ESPE 2024 Demonstrate Sustained Growth on Oral LUM-201 to 24 Months in PGHD and Correlation of Growth to LUM-201's Unique Pulsatile Mechanism of Action
AUSTIN, Texas, Nov. 21, 2024 (GLOBE NEWSWIRE) -- Lumos Pharma, Inc. (NASDAQ:LUMO), a clinical-stage biopharmaceutical company focused on therapeutics for rare diseases, announced that new analyses of data from its Phase 2 OraGrowtH210 and OraGrowtH212 clinical trials were presented orally at the 62nd Annual European Society for Paediatric Endocrinology Meeting, or ESPE 2024, held November 16-18, 2024 in Liverpool, UK.
"The new analyses and updated data from our Phase 2 OraGrowtH210 and OraGrowtH212 Trials presented at ESPE this week demonstrate sustained growth on LUM-201 in moderate Pediatric Growth Hormone Deficiency (PGHD) to 24 months, as well as the correlation of LUM-201's pulsatile mechanism of action (MOA) to growth," said John C. McKew, PhD, President and Chief Scientific Officer of Lumos Pharma. "We are encouraged by these data and look forward to advancing oral LUM-201 in a Phase 3 clinical trial in moderate PGHD next year."
In the oral presentation of Abstract FC7.6 on Sunday, November 17th, entitled, Growth, IGF-1 and IGFBP-3 Responses to Oral LUM-201 in OraGrowtH210 and OraGrowtH212 Trials in Pediatric Growth Hormone Deficiency (PGHD) Over 12 to 24 Months on Treatment (Elżbieta Petriczko, MD, PhD, et al) [link], the investigator reviewed updated combined data from the Phase 2 OraGrowtH210 and OraGrowtH212 Trials out to 24 months following treatment with LUM-201.
- Results showed that at six months on LUM-201, a significant increase over baseline in Annualized Height Velocity (AHV) was observed for the combined 1.6 and 3.2 mg/kg/day doses. At baseline, AHV was 4.6 cm/yr for 37 subjects for which baseline data were available vs 7.8 cm/yr at 6 months on LUM-201 for 66 subjects.
- Results also showed that growth rates on oral LUM-201 (combined 1.6 and 3.2 mg/kg dose cohorts) were sustained out to 24 months with AHVs of 7.3 (N=65), 7.5 (N=36), and 7.3 (N=20) cm/yr at 12, 18, and 24 months, respectively [graphic below].
- Combined results also demonstrated significant increases in IGF-1 and IGFBP-3 levels from baseline out to 24 months, with IGF-1 increasing from 13.1 (baseline) to 25.5 (12 months) to 29.2 (24 months) nmol/L and IGFBP-3 increasing from 133.5 (baseline) to 179.6 (12 months) to 186.2 (24 months) nmol/L.
- Conclusions: LUM-201 shows a significant increase in AHV at 6 months, and the effect continues with a minimal decrease in AHV through 24 months. Compared to historical rhGH (KIGS)1, LUM-201 has a smaller drop in AHV from 12 months to 24 months. LUM-201 significantly increases IGF-1 and IGFBP-3 levels at 12 months which continues to 24 months. A favorable investigational safety profile has been observed to date.
In the late-breaking oral presentation of Abstract FC15.2 on Monday, November 18th, entitled, Amount and Pattern of Pulsatile GH Secretion Induced by the Oral Growth Hormone Secretagogue LUM-201 Is Related to Growth and IGF-1 Responses in Moderate Pediatric Growth Hormone Deficiency (PGHD) (Peter E. Clayton, MD, et al) [link], the investigator reviewed data from OraGrowtH212 demonstrating the relationship between pulsatile GH profiles and both the growth and IGF-1 responses to LUM-201 treatment.
- Data from 22 prepubertal children with moderate PGHD from the OraGrowtH212 Trial were evaluated with subjects grouped into tertiles based on 6-month annualized height velocity (AHV).
- Pulsatile growth hormone (GH) pulse assessments at baseline and at 6 months (M6) were characterized using 1) Approximate Entropy (ApEn, scale 0-1) examining degree of orderliness over the whole profile and 2) Functional Principal Component Analysis (FPCA) identifying where within the 12-hour profile, divided into 4-hour periods, the dominant variation occurred.
- Results of 6-month treatment with LUM-201:
- Pulsatile GH secretion, ApEn, IGF-1 SDS and IGFBP-3 SDS increased from baseline to M6.
- Greater M6 AHV was associated with an earlier periodicity of augmented pulsatile GH secretion [graphic below].
- Conclusion: Both amount and pattern of GH secretion are important for growth and IGF-1 responses to LUM-201.
