入选标准
- •Adult female subjects aged 18 to 80 years, inclusive, or adult male subjects aged 50 to 80 years, inclusive, at the time of signing the informed consent form (ICF).
- •. Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject. Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable.
- •Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study prior to initiation of any protocol-mandated procedures.
- •Willingness and ability to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
- •Subjects must have completed a prior seralutinib PAH study and, in the opinion of the Investigator and Sponsor, have been compliant with study procedures and have completed treatment with IP through parent study EOT visit. See exception(s) for public health emergency visit/procedure delays specified in Appendix 6, Section 10.
- •Treatment with standard of care PAH disease-specific background therapies (stable dose).
- •Women of childbearing potential must have a negative urine or serum pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin [hCG]) at extension enrollment visit before first administration of seralutinib in this study. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test is required, and results must be negative.
- •Women of nonchildbearing potential: Evidence of post-menopausal status. Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply: Women < 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy tubal ligation [if considered an effective form of sterilization in a specific country or region], or hysterectomy). − Women ≥ 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses > 1 year ago, had chemotherapy-induced menopause with last menses > 1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy, tubal ligation [if considered an effective form of sterilization in a specific country or region], or hysterectomy).
- •Women of childbearing potential who are not abstinent and intend to be sexually active with a non-sterilized male partner must be willing to use a highly effective method of contraception (defined in Appendix 4, Section 10.4) from consent through 30 days following the last administration of seralutinib; acceptable methods include hormonal contraception (oral contraceptives – as long as on stable dose, patch, implant, or injection), intrauterine devices or other form of highly effective contraception.
- •Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject. Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable.
- •Nota: la abstinencia sexual solamente es aceptable si está en consonancia con el estilo de vida preferido y habitual de la paciente. La abstinencia periódica, el método del ritmo y el coitus interruptus (marcha atrás) no se consideran aceptables.
- •Male subjects: Non-sterilized male subjects who are not abstinent and intend to be sexually active with a female partner of childbearing potential must use a male condom from consent through 90 days after the last dose of seralutinib. Male subjects should refrain from sperm donation throughout this period (except for male subjects participating in fertility analysis as part of this protocol).
排除标准
- •Medical Conditions:
- •Persistent and clinically significant systemic hypertension as evidenced by sitting systolic blood pressure > 160 mm Hg or sitting diastolic blood pressure > 100 mm Hg after a period of rest at the extension study initial visit, or hypotension as evidenced by systolic blood pressure < 90 mm Hg during the extension study initial visit.
- •Interval history of newly developed left-sided heart disease with onset or severity increased after participation in the parent study, and/or clinically significant cardiac disease, including but not limited to any of the following: a. Aortic or mitral valve disease (stenosis or regurgitation) defined as greater than mild aortic insufficiency, mild aortic stenosis (AS), mild mitral stenosis (MS), moderate mitral regurgitation (MR); b. Mechanical or bioprosthetic cardiac valve; c. Pericardial constriction or pericardial effusion with tamponade physiology; d. Restrictive or congestive cardiomyopathy; e.

- •Potentially life-threatening cardiac arrhythmia with an ongoing risk.
- •Uncontrolled bacterial, viral, or fungal infections which require systemic therapy.
- •Other severe acute or chronic medical or laboratory abnormality that may increase the risk associated with study participation or seralutinib administration or may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the subject inappropriate for entry into this study; including but not necessarily limited to the following: malignancy within 5 years of extension enrollment visit, with the exception of effectively treated or excised localized non-metastatic basal cell carcinoma of the skin and in situ carcinoma of the cervix; psychiatric disorder that compromises ability to give informed consent, substance abuse, coagulopathy, history of stroke, transient ischemic attack (TIA) requiring concurrent oral coagulation therapy, or intracranial hemorrhage; history of pulmonary embolus or deep vein thrombosis (DVT), history of vasovagal syncope with phlebotomy.
