RARITAN, NJ, September 6, 2023 - The Janssen Pharmaceutical Companies of Johnson & Johnson today announced its decision to stop the Phase 3 MACiTEPH study evaluating macitentan 75 mg in patients with Chronic Thromboembolic Pulmonary Hypertension (CTEPH) due to futility. The decision to stop the trial was made in accordance with a recommendation by the study’s independent data monitoring committee following a pre-planned interim analysis. No new safety signals were observed.
The interim results of MACiTEPH do not impact any of the Company's commercialized pulmonary hypertension medicines. Additionally, the pivotal Phase 3 UNISUS study, which aims to establish the superiority of a 75 mg dose of macitentan over the currently available 10 mg dose in patients with pulmonary arterial hypertension, is currently continuing as planned.
Janssen is proud of its decades-long commitment to advancing science in support of patients with pulmonary hypertension.

It evaluates the efficacy and safety of macitentan 75 mg compared to placebo on exercise capacity, the primary efficacy endpoint, in a broad population including inoperable patients and those who underwent mechanical treatment, including pulmonary endarterectomy or balloon pulmonary angioplasty.
