Lumos Pharma Announces New Data and Analysis of 15 Subjects from OraGrowtH212 Trial Presented at the 2023 ESPE Annual Meeting
•Deconvolution Analysis Shows 60% Increase in GH Secretion, Comparable to Established Values in Normal Children
•Analysis Shows Annualized Height Velocity Increased ~62% Compared to Baseline
•Data Support LUM-201 Mechanism of Action in Moderate PGHD Patient Population
AUSTIN, TX, September 26, 2023 – Lumos Pharma, Inc. (NASDAQ:LUMO), a biopharmaceutical company advancing an oral therapeutic candidate for moderate Pediatric Growth Hormone Deficiency (PGHD) through Phase 2 clinical trials, announced today that an analysis of interim data from its OraGrowtH212 Trial was given as an oral presentation at the 2023 annual meeting of the European Society for Paediatric Endocrinology (ESPE), held in The Hague, Netherlands, September 21-23, 2023.
“These new data and analysis of interim data from our OraGrowtH212 trial show that oral LUM-201 restored GH secretion to similar levels seen in normally growing children by enhancing endogenous pulsatile GH secretion while maintaining normal feedback control of IGF-1,” said John C. McKew, PhD, President and Chief Scientific Officer of Lumos. “The presented results add to the growing body of evidence supporting the physiologic mechanism of action for LUM-201, as well as its potential as a treatment for moderate PGHD. As we look ahead to our topline data readout from these trials in the fourth quarter, these results and the others we have released recently add to our confidence that at least one of the LUM-201 dose cohorts will meet growth expectations based on historical averages, and that the LUM-201 mechanism of action and potency can elicit sustained improvements in growth in the moderate PGHD patient population. We look forward to our topline data announcement and to continuing to advance our LUM-201 clinical program as potentially the first oral therapeutic for PGHD.”
The oral presentation, Deconvolution Analysis: Oral GH secretagogue (LUM-201) enhances growth in individuals with moderate Pediatric Growth Hormone Deficiency (PGHD) by enhancing endogenous GH secretion and increasing IGF-1 (Fernando Cassorla, MD, et al), was given in a late breaking session, Saturday, September 23, 9:30-10:30 AM CET (Local Time). The slides presented at ESPE are available on the Posters & Publications page under the Investors & Media section of Lumos Pharma’s website.
The objective of the analysis was to characterize growth hormone (GH) profiles, defined by deconvolution analysis, based on the GH concentration sampled over 12 hours at baseline and after 6 months of therapy with daily oral LUM-201 to illustrate how LUM-201 increases annualized height velocity (AHV), total GH secretion, and serum IGF-1 and IGFBP3 in individuals with moderate PGHD. Fifteen prepubertal, naive moderate PGHD subjects were screened with a predictive enrichment marker (PEM) test to assess their acute response to oral LUM-201 (0.8mg/kg), with a positive test having a peak GH ≥5 ng/ml with a basal IGF-1 >30 ng/ml. At baseline, subjects (10M:5F)
were (mean ± SD) aged 7.9±1.4 years, with IGF-1 SDS -0.82±0.9, and peak GH 7.2±2.2 ng/mL (clonidine stimulation), consistent with moderate PGHD.
Deconvolution analysis was performed on serum GH measured every 10 minutes (0800 h to 2000 h). Patients were randomized to receive 1.6 mg/kg/day or 3.2 mg/kg/day of oral LUM-201. Both baseline characteristics and acute GH responses to the PEM test (p=0.9) and the day 1 PEM test doses were not different between the groups (34.8±6.6 ng/ml for 1.6mg/kg and 38.2±11.2 ng/ml for 3.2mg/kg, p=0.7). The groups were therefore combined in this analysis.
Results showed that after 6 months of treatment with LUM-201, GH, IGF parameters, and AHV increased 60-80% (see Table 1 for means (SD)) from baseline. The study author concluded that LUM-201 enhanced pulsatile GH secretion to similar levels observed in normal growing children (estimated at ~3.5 μg/kg/12h; Albertsson-Wikland et al JCEM 1994), and that restoration of physiological pulsatile GH secretion and IGF-1 were sufficient to support normal growth. The study’s author further noted that LUM-201 in the potential treatment of moderate PGHD has the advantages of being taken orally, enhancing endogenous pulsatile GH secretion, and therefore maintaining normal feedback mechanisms to restore more physiological growth.

About PGHD and the Therapeutic Landscape
PGHD is the consequence of inadequate secretion of growth hormone from the pituitary gland in children resulting in low growth hormone (GH) in the body, insufficient production of downstream signaling molecules required for growth, and the subsequent lack of growth. The prevailing standard of care for PGHD consists of a daily injection of exogenous GH administered for approximately 7 years on average. Several once-weekly injectable GH therapies have recently been approved in the US and internationally to treat PGHD. LUM-201, also known as ibutamoren, is an orally administered investigational small molecule that promotes the secretion of GH from the pituitary gland and represents an opportunity for appropriately selected patients to avoid the daily or weekly injections involved with current or forthcoming therapies. LUM-201 has been observed to increase the amplitude of endogenous pulsatile GH secretion, which mimics the natural pattern of GH secretion.
