Chiesi Group and Oak Hill Bio will collaborate closely to develop OHB-607, a clinical-stage investigational drug candidate, to treat complications of extremely premature birth; This agreement expands Chiesi's commitment to Neonatology, a highly strategic area for the company; Partners intend to restart Phase 2b clinical trial of OHB-607 in 2024. PARMA, Italy and CAMBRIDGE, Mass., Jan. 9, 2024 /PRNewswire/ -- Chiesi Farmaceutici S.p.A ("Chiesi Group"), an international, research-focused biopharmaceuticals and healthcare group, and Oak Hill Bio, a clinical-stage neonatology and rare disease therapeutics company, today announced the execution of an agreement to develop, manufacture, and commercialise OHB-607, an investigational drug candidate being developed to treat complications of extremely premature birth. OHB-607 is a recombinant version of insulin-like growth factor-1 (IGF-1), a key driver of fetal growth and development, and its binding protein, IGFBP-3. Babies born at less than 28 weeks gestational age have low levels of IGF-1 and face high risk of severe bronchopulmonary dysplasia (BPD), which may lead to chronic lung disease. There are no approved medicines to prevent BPD in pre-term infants. OHB-607, a human IGF-1 replacement, is designed to help prevent BPD and its long-term respiratory consequences. "Targeting a challenging complication of prematurity with an innovative solution is an important step given the potential benefits it may bring to the babies born extremely prematurely" commented Giuseppe Accogli, CEO of Chiesi Group. "This potentially transformative therapy may provide a breakthrough solution for bronchopulmonary dysplasia, one of the diseases with the highest unmet medical needs in the field of neonatology." Chiesi and Oak Hill Bio intend to restart a Phase 2b clinical trial in 2024 in the United States, Europe, and Japan. Clinical studies conducted to date have demonstrated OHB-607's potential to significantly reduce the risk of severe BPD. "We believe that OHB-607 has the potential to be the first major therapeutic breakthrough for extremely preterm infants since lung surfactants were first approved more than 30 years ago," said Josh Distler, President, and Chief Financial Officer of Oak Hill Bio. "We are thrilled to partner with Chiesi. Their deep expertise in neonatology will help to rapidly advance this promising therapy to patients." SOURCE Chiesi

About Bronchopulmonary Dysplasia (BPD)2 Bronchopulmonary dysplasia (BPD) is a form of chronic lung disease affecting newborns who are born prematurely, particularly those who are exposed to oxygen therapy or to use of breathing machine for a long time. Due to their immaturity, the lungs of premature newborns are particularly vulnerable and may undergo abnormal development in the postnatal period; in particular, high amounts of inhaled oxygen and pressure may overstretch the alveoli, causing inflammation and damage to the inside lining of the airways, the alveoli and the blood vessels around them. The degree of prematurity in an infant is largely what puts a child at risk of developing BPD. The majority of newborns who develop BPD are born more than 10 weeks early, weigh less than two pounds at birth, and are born with breathing problems. BPD is rare in infants born after 32 weeks of pregnancy. BPD is the most common respiratory complication of premature infants affecting on average 40-50% of those born at gestational age below 28 weeks, which might lead to increased mortality longer hospitalization rate and cost burden, as well as long-term respiratory morbidity with lifelong impact on respiratory function. About OHB-607 OHB-607, is a complex of a recombinant version of insulin-like growth factor-1 (IGF-1) formulated with its binding protein for prevention of bronchopulmonary dysplasia in preterm infants. IGF-1 is a growth factor critical for organ growth and development in the fetus. Mothers are the primary source of IGF-1 for the developing fetus until reaching about 30 weeks gestational age. IGF-1 levels typically rise in the third trimester while the level of this protein is low in infants born prematurely due to loss of maternal source of IGF-1. Natural history studies document the association of lower IGF-1 concentrations with BPD in very preterm infants and provide rationale for IGF-1 treatment to restore levels which would have been present in case of a full-term pregnancy, supporting lung development3.

-- 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. For a link to the Company’s conference call and presentation of the data refer to the Events & Presentations page in the Investors & Media section of the Company’s website. 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.
