If approved, Yuvanci® would become the only single tablet combination for treatment for patients with PAH

Johnson & Johnson’s comprehensive PAH portfolio has the potential to cover all guideline-recommended treatment pathways BEERSE,

BELGIUM (26 July, 2024) – Janssen-Cilag International NV, a Johnson & Johnson company, announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has recommended the Marketing Authorisation (MA) of Yuvanci®. Yuvanci® is a single tablet combination therapy of macitentan 10 mg and tadalafil 40 mg (M/T STCT) as a substitution therapy for the long-term treatment of pulmonary arterial hypertension (PAH) in adult patients of WHO Functional Class (FC) II to III, who are already treated with the combination of macitentan and tadalafil given concurrently as separate tablets.1

PAH is a rare, progressive and life-threatening disease characterised by the constriction of small pulmonary arteries and elevated blood pressure (hypertension) in the pulmonary circulation that eventually leads to right heart failure and death. 2,3 The 2022 European Society of Cardiology/European Respiratory Society (ESC/ERS) pulmonary hypertension (PH) guidelines have strengthened recommendations on initial double combination therapy with macitentan and tadalafil for PAH patients without cardiopulmonary comorbidities.4 However, this requires patients to take multiple pills as no single tablet that targets two or more PAH-specific pathways is available for these patients in Europe.

“PAH is a devastating disease affecting people of all ages and the burden the condition places on the daily lives of people living with it should not be underestimated,4,5” said Tamara Werner-Kiechle, M.D., EMEA Therapeutic Area Lead Neuroscience and Cardiopulmonary, Johnson & Johnson Innovative Medicine. “Bringing a single tablet combination follows the ESC/ERS guidelines, which recommend initial double and triple combination therapy,4 and could represent an important new option for adults living with PAH who face complex treatment regimens. 6,7”

The CHMP positive opinion for M/T STCT is based on data from the Phase 3 A DUE study. The A DUE study was a multinational, multi-centre, double-blind, adaptive, randomised, active-controlled, parallel-group study in 187 adult patients with PAH (WHO FC II to III).8 The study was designed to compare the efficacy and safety of M/T STCT to each monotherapy, macitentan or tadalafil. 8 The study met its primary endpoint, demonstrating change in pulmonary vascular resistance (PVR) expressed as the ratio of Week 16 to baseline in patients with PAH, for the comparison of M/T STCT versus the individual monotherapies.8

Treatment with M/T STCT resulted in a statistically significant effect of 0.71 (95% Confidence Interval [CI] 0.61, 0.82, p < 0.0001) representing a 29% reduction in PVR as compared to macitentan, and of 0.72 (95% CI 0.64, 0.80, p < 0.0001) representing a 28% reduction in PVR as compared to tadalafil.8 Consistent efficacy of M/T STCT on the primary endpoint was seen across subgroups of age, sex, race, and baseline WHO FC.1,8 Additionally, consistent efficacy was observed in patients FOR EUROPEAN MEDICAL AND TRADE MEDIA ONLY 2 CP-464755 July 2024 who were either treatment-naïve, or previously exposed to an endothelin receptor antagonist (ERA) or phosphodiesterase type 5 inhibitor (PDE5i). 8

The most common adverse events (AEs) (occurring in the M/T STCT-treated patients) from the combined double-blind/openlabel A DUE study data were anaemia/haemoglobin decrease, oedema/fluid retention, and headache. The most common serious AE was anaemia, followed by palpitations, hypotension, intermenstrual bleeding, oedema/fluid retention and influenza. 1

“Today’s positive opinion represents a significant step forward and underlines our commitment to providing solutions for patients in the PAH community,” said James F. List, M.D., Ph.D., Global Therapeutic Area Head, Cardiopulmonary, Johnson & Johnson Innovative Medicine. “We continue our commitment to transform PAH into a manageable condition and we look forward to working with health authorities to bring our single tablet combination therapy to adult patients in need across the region as soon as possible.”

Pending European Commission (EC) approval, Yuvanci® will be the only single tablet combination therapy in Europe for PAH. Approval by the EC will also mean J&J’s PAH portfolio will have the potential to cover all guideline-recommended treatment pathways. Today’s positive CHMP opinion follows the New Drug Application (NDA) approval of OPSYNVI® (macitentan and tadalafil) by the U.S. Food and Drug Administration (FDA) in March 2024 for the treatment of patients with PAH. 9

About Pulmonary Arterial Hypertension (PAH)

PAH is a specific, rare form of pulmonary hypertension (PH) with approximately 48-55 cases per million adults, and there is currently no cure. 2,4 PAH is a serious, progressive disease with a variety of aetiologies and has a major impact on patients' functioning as well as their physical, psychological and social wellbeing. 3,5

PAH evolves silently over years, as symptoms such as breathlessness, dizziness and fatigue are non-specific and can be confused with more common conditions like asthma and chronic obstructive pulmonary disease (COPD).2 On average it takes two years from the onset of symptoms for PAH to be diagnosed, and in some instances up to four years. 2,10 This means that by the time a patient is diagnosed, their PAH is typically in an advanced stage with severe symptoms and a poor prognosis.2 The last decade has seen significant advances in the understanding of the pathophysiology of PAH, transforming the prognosis for PAH patients from symptomatic improvements in exercise tolerance 10 years ago, to delayed disease progression today.2 However, PAH patients are facing a greater pill burden due to complex treatment regimens involving multiple pills.6,7 The PAH patient population is also ageing, leading to an increasing number of concomitant medications to treat comorbidities. 4

About macitentan/tadalafil STCT

Macitentan 10 mg and tadalafil 40 mg STCT is a therapy that combines the ERA, macitentan, and the PDE5i, tadalafil.1 Macitentan works by dilating the narrow blood vessels between the right heart and the lungs, making it easier for the heart to pump blood through them, as well as reducing and preventing the overgrowth of cells in the walls of these vessels.11 Tadalafil helps to relax the blood vessels in the lungs, widening them to decrease the pulmonary blood pressure to the heart and improve its function.12

About the A DUE study

The A DUE study was a multi-national, multi-centre, double-blind, adaptive, randomised, active-controlled, parallel-group study in 187 patients with PAH (WHO FC II–III).8 The study was designed to compare the efficacy and safety of Yuvanci® single tablet combination therapy of macitentan 10 mg and tadalafil 40 mg (M/T STCT) to each monotherapy, macitentan or tadalafil.8 Patients with pulmonary vascular resistance (PVR) of at least 240 dyn×s/cm5 were randomised to receive M/T STCT (n=108), 10 mg macitentan monotherapy (n=35) or 40 mg tadalafil monotherapy (n=44), once daily. Patients who were not on a therapeutic PDE-5i dose at baseline, received a 1-week titration period of macitentan 10 mg and tadalafil 20 mg. Patients who received treatment during the double-blind treatment period (n=186) were either treatment-naïve (52.7%) to any PAH specific monotherapy, or on an ERA (17.2%), or a PDE5i (30.1%). Patients enrolled had idiopathic PAH (50.5%), heritable PAH (4.8%), PAH associated with connective tissue disease (34.9%), or PAH associated with congenital heart disease (3.2%). The mean age was 50.2 years (range 18–80), 20.4% of patients were ≥ 65 years of age, 22% were male FOR EUROPEAN MEDICAL AND TRADE MEDIA ONLY 3 CP-464755 July 2024 and 61.8% were white. At the time of enrollment, 51.1% of patients were WHO FC II and 48.9% were WHO FC III.1 The primary endpoint of the study was change in PVR expressed as the ratio of Week 16 to baseline in patients with PAH, for the comparison of M/T STCT versus the individual monotherapies.1 The key secondary endpoint was change in mean 6-minute walk distance (6MWD) from baseline to 16 weeks of therapy in patients with PAH, for the comparison of M/T STCT versus the individual monotherapies.1
