Chiesi Group and Oak Hill Bio have announced that the first European patient has been enrolled in a phase 2b study evaluating a drug candidate for preventing complications of extremely premature birth. The open-label trial, re-launched in the US in May, is comparing the efficacy and safety of OHB-607 against standard neonatal care for preventing bronchopulmonary dysplasia (BPD) and other complications of prematurity among infants born between 23 and 28 weeks of gestation. There are currently no approved therapies for BPD, which affects up to 50% of infants born at less than 28 weeks of gestational age. The condition has a direct impact on lung function and is associated with greater mortality, increased hospitalisation, as well as long-term respiratory morbidity and neurodevelopment disability. OHB-607 is the recombinant form of human insulin-like growth factor-1 (IGF-1), a key driver of the growth and gestational development of vital organs, complexed with its main binding protein, and has already been shown in a phase 2a trial to decrease the occurrence of severe BPD. Mothers are the primary source of IGF-1 until about 30 weeks gestational age, and research has shown a link between lower serum IGF-1 levels at birth in extremely preterm infants and an increased risk of BPD, retinopathy of prematurity, neurodevelopmental and overall growth impairment. In the study, which is aiming to enrol at least 105 infants in Europe, OHB-607 will be administered by continuous intravenous infusion from 24 hours after birth until 30 weeks post-menstrual age, with all infants also receiving standard neonatal care. Diego Ardigò, executive vice president, global research and development at Chiesi, said: “The restart of this study marks a significant milestone highlighting the shared commitment of Chiesi and Oak Hill Bio to advance solutions for the vulnerable group of extremely premature infants, now including patients from Europe. Addressing the medical needs of these infants goes beyond scientific inquiry; it’s a moral imperative to safeguard their well-being.” Sharing a similar sentiment, Victoria Niklas, chief medical officer at Oak Hill Bio, said: “As a neonatologist, I’m thrilled that we have restarted this groundbreaking clinical trial… OHB-607 can potentially improve outcomes for infants born extremely premature.”

PARMA, Italy--( BUSINESS WIRE )--Oak Hill Bio, a clinical-stage neonatology and rare disease therapeutics company, and Chiesi, an international, research-focused biopharmaceutical company (Chiesi Group), announced that the first European patient has been enrolled in a Phase 2b clinical study, restarted in May, to assess the efficacy and safety of OHB-607, an investigational drug candidate being developed to prevent complications of extremely premature birth, including bronchopulmonary dysplasia (BPD), a serious condition for which there are no approved therapies. “ As a neonatologist, I’m thrilled that we have restarted this groundbreaking clinical trial previously paused during the out-licensing process to Oak Hill Bio. OHB-607 can potentially improve outcomes for infants born extremely premature,” said Victoria Niklas, Chief Medical Officer at Oak Hill Bio. “ At Oak Hill Bio, we are committed to advancing the field of neonatology and delivering the best possible care and outcomes to patients together with our partners at Chiesi.” “ The restart of this study marks a significant milestone highlighting the shared commitment of Chiesi and Oak Hill Bio to advance solutions for the vulnerable group of extremely premature infants, now including patients from Europe,” commented Diego Ardigò, Executive Vice President, Global Research & Development, Chiesi Group. “ Addressing the medical needs of these infants goes beyond scientific inquiry; it’s a moral imperative to safeguard their well-being.” About the Phase 2b Study The Phase 2b clinical study is a multicenter, randomized, open-label, two-arm study designed to evaluate the efficacy and safety of OHB-607 compared to standard neonatal care for preventing BPD and other complications of prematurity among infants born extremely premature (between 23 and 28 weeks of gestation). The study, which opened in the United States in May 2024, is now being extended to Europe (Finland, Germany, Ireland, Italy, Netherlands, Portugal, Spain, and UK) and Japan. It is designed to enroll at least 105 infants in Europe. OHB-607 will be administered by continuous intravenous infusion from 24 hours after birth until 30 weeks postmenstrual age. All infants will simultaneously receive standard neonatal care based on the individual infant’s condition and local guidelines. The primary endpoint of the study is the reduction in the incidence of severe BPD or death by 36 weeks postmenstrual age compared to extremely premature infants receiving standard neonatal care alone. The study will also evaluate the impact of OHB-607 on weaning from respiratory technology support through 12 months corrected age as a longer-term respiratory outcome measure, the impact on neurodevelopment, and the incidence of other complications of prematurity, including intraventricular hemorrhage (bleeding in the brain) and retinopathy of prematurity (vision impairment and blindness). The study will utilize a modified National Institute of Child Health and Human Development (NICHD) score to define BPD severity grading, allowing the comparison of infants with the most severe form of the disease.

About OHB-607 OHB-607 is the recombinant form of human insulin-like growth factor-1 (IGF-1) complexed with its main binding protein (rhIGFBP-3). IGF-1 is a key driver of the growth and gestational development of vital organs, including the lung, eye, and brain. Mothers are the primary source of IGF-1 for the developing fetus until about 30 weeks gestational age, when the fetal liver takes over. As a result, infants born before 28 weeks of gestational age have low levels of IGF-1, which is believed to result in the failure of organs to grow and develop normally. Following preterm birth, serum IGF-1 levels decrease rapidly and remain low for the first weeks of life relative to corresponding fetal levels in utero. Longitudinal studies report an association between lower serum IGF-1 levels at birth in extremely preterm infants and an increased risk of BPD, retinopathy of prematurity, neurodevelopmental and overall growth impairment. This provides a rationale for evaluating OHB-607 to restore IGF-1 to levels that would have been present in utero in a full-term pregnancy to potentially support the normal growth and development of the lung and other organs. 2 OHB-607 has the potential to be the first major respiratory therapeutic breakthrough for extremely preterm infants since lung surfactants were first approved more than 30 years ago. About Bronchopulmonary Dysplasia in Europe (BPD) 3 BPD is the most common complication of prematurity, resulting in chronic lung disease affecting, on average, 40-50% of infants born at less than 28 weeks of gestational age. 4 Beyond BPD’s direct impact on lung function, it can also lead to greater mortality, increased hospitalization and cost burden, as well as long-term respiratory morbidity and neurodevelopment disability. 5 While the pathogenesis of BPD is multifactorial and not completely understood, gestational age is the most significant predictor of BPD and chronic lung disease following preterm birth. Additional factors, including birth weight, growth restriction, lung function, and gender, may influence the severity of BPD. The care practices necessary to sustain life after preterm birth result in direct and bystander injury to the developing lung, particularly in infants requiring high levels of oxygen therapy and invasive ventilation for extended periods. OHB-607 has the potential to foster lung development and reduce the need for respiratory support, which could, in turn, reduce the severity of BPD and its long-term outcomes.
