Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   42869   clinical trials with a EudraCT protocol, of which   7063   are clinical trials conducted with subjects less than 18 years old.
    The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).


    Phase 1 trials conducted solely in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System

The study will use specialized software to determine change from baseline in pulmonary vasculature blood volume, pulmonary blood volume as a percent of total lung volume, fibrosis score, and image-based ventilation to perfusion score.
    E.3Principal inclusion criteria
    Subjects must meet ALL the following inclusion criteria to be enrolled into the extension:

    Age and Sex
    1. 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).

    Type of Subject and Disease Characteristics
    2. Subjects must have completed a prior GB002 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.
    3. Treatment with standard of care PAH disease-specific background therapies (stable dose).

    Contraception
    Contraception use by men or women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
    4. 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 enrolment visit before first administration of GB002 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.
    5. 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, 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, or hysterectomy).

    6. 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 from consent through 30 days following the last administration of GB002; 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.
    Note: A vasectomized partner is acceptable.
    7. 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 GB002. Male subjects should refrain from sperm donation throughout this period (except for male subjects participating in fertility analysis as part of this protocol).
    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.

    Informed Consent
    8. 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.
    9. Willingness and ability to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
    E.4Principal exclusion criteria
    The subject must be excluded from participating in the study if he/she meets any of the following:

    1. Persistent and clinically significant systemic hypertension or hypotension.
    2. Interval history of newly developed left-sided heart disease with onset or severity increased after participation in the parent or lead in-study, and/or clinically significant cardiac disease, unless reviewed and approved as eligible to participate in the study by Sponsor’s Medical Monitor (or designee), including but not limited to any of the following:

    i. History of severe and untreated obstructive sleep apnoea.
    3. Potentially life-threatening cardiac arrhythmia with an ongoing risk.
    4. Uncontrolled bacterial, viral, or fungal infections which require systemic therapy.
    5. Other severe acute or chronic medical or laboratory abnormality that may increase the risk associated with study participation or GB002 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 enrolment 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 haemorrhage; history of pulmonary embolus or deep vein thrombosis (DVT), history of vasovagal syncope with phlebotomy.
