The official eligibility criteria

Registry text, reproduced exactly. These are the words the trial's sponsor published on ClinicalTrials.gov. They have not been edited, shortened or rewritten, and they are written for researchers rather than for patients.

Inclusion Criteria:

1. Subjects must have completed a qualifying last visit in a prior seralutinib PAH study on investigational product (IP) and in accordance with the protocol.

2. Evidence of an informed consent document, signed and dated by the subject, indicating that the subject has been informed of all pertinent aspects of the study prior to initiation of any subject-mandated procedures.

3. Willingness and ability to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures

4. Women of childbearing potential (WOCBP) must have a negative urine or serum pregnancy test at enrollment visit before first administration of Investigational Product (IP) in this study.

5. WOCBP 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 from consent through 30 days following the last administration of IP.

6. 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 IP.

Exclusion Criteria:

1. Severe acute or chronic medical or laboratory abnormality that may increase the risk associated with study participation or seralutinib administration, unless associated with an ongoing AE and discussed with the Sponsor's medical monitor (MM) (or designee).

2. Have any other condition or reason that, in the opinion of the Investigator, would prohibit the subject from participating in the study.

Voxsanity reformats data from public registries into this layout. It does not edit, interpret or add to what the registry published.

Not medical advice.

Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
