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   42585   clinical trials with a EudraCT protocol, of which   7011   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  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

Permitted are also treatments of the rheumatologic disease. However, these drugs must have been started at least 1 month before right heart catheterization.
    5. Right-heart catheterization results must not be older than 1 month at Visit 1 (will be considered as baseline values, the time frame can be prolonged up to 6 months, if the patient has had no signs of clinical changes as >10% change of 6MWD, WHO FC, > 30% change in NTproBNP) and must have been measured in the participating centre under standardized conditions (refer to the study specific Swan Ganz catheterization manual). If the respective measurements have not been performed in context with the patient’s regular diagnostic work up, they have to be performed as a part of the study during the Pre-Study Phase (after the patient signed the informed consent).
    6. Women without childbearing potential defined as postmenopausal women aged 55 years or older, women with bilateral tubal ligation, women with bilateral ovariectomy, and women with hysterectomy can be included in the study. Women of childbearing potential can only be included in the study if all of the following applies (listed below): a. Negative serum pregnancy test at screening and a negative urine pregnancy test at study start (visit 1). b. Agreement to undertake monthly urine pregnancy tests during the study and up to at least 30 days after study treatment discontinuation. These tests should be performed by the patient at home. c. - Agreement to follow the contraception scheme as stated from screening until at least 30 days after study treatment discontinuation.
    7. Patients who are able to understand and follow instructions and who are able to participate in the study for the entire period.
    8. Patients must have given their written informed consent to participate in the study after having received adequate previous information and prior to any study-specific procedures.
    E.4Principal exclusion criteria
    1. Patients with systemic lupus erythematosus.
    2. Concomitant PAH-targeted treatment is not allowed during the study.
    3. Concomitant treatment with phosphodiesterase 5 inhibitors, endothelin receptor antagonists and prostacyclin analogues due to digital ulcers is contraindicated and should have a washout-phase of 3 days at the time of right heart catheterization. Intravenous treatment with prostacyclin analogues should not be performed within 1 week of right heart catheterization. Any decision to discontinue above-mentioned drugs will be made by the clinicians and the patient at screening.
    4. Pulmonary hypertension explained by other cause including group 2, 3, 4 and 5 PH according to the current guidelines.
    5. Cardiac comorbidity, defined with three or more of the following conditions: uncontrolled arterial hypertension, diabetes mellitus, body mass index >35, left atrial enlargement >20 cm², atrial fibrillation, left ventricular ejection fraction <50%.
    6. Pulmonary comorbidity, defined as forced vital capacity (FVC) ≤70; forced expiratory volume in 1 second (FEV1) ≤50%; diffusion capacity of the lung (DLCO) ≤40%. FVC may be <70/ if high resolution computed tomography shows <20% lung fibrosis.
    7. Patients with a medical disorder, condition, or history of such that would impair the patient's ability to participate or complete this study in the opinion of the investigator.
    8. Patients with underlying medical disorders with an anticipated life expectancy below 2 years (e.g. active cancer disease with localized and/or metastasized tumour mass).
    9. Patients with a history of severe or multiple drug allergies (defined as allergic reactions to three or more structurally unrelated drugs).
    10. Patients with hypersensitivity to the investigational drug or any of the excipients.
    11. Contraindications according to summary of product characteristics of riociguat (e.g. arterial hypotension with systolic blood pressure <95 mmHg; nitrates)
    12. Participation in any clinical drug trial within 4 weeks prior to screening of this study and/or patient, who is scheduled to receive an investigational medicinal product (IMP) during the course of this study
    13. Background therapy with highly anti-fibrotic drugs (pirfenidone ) or nintedanib, prednisolone >10 mg/day or any other PAH specific treatment.
    E.5 End points
    E.5.1Primary end point(s)
    The evaluation of the primary efficacy endpoint will be the change from baseline to 24 weeks in pulmonary vascular resistance. The primary analysis set will be the intention to treat set.
    The main comparison will be the difference in treatment effect between riociguat (MK-4836) and placebo. 95% confidence intervals of treatment difference will also be calculated. The primary comparison will be an ANCOVA model including baseline scores as covariate.
    If the preconditions for an ANCOVA analysis are not met, the primary endpoint will be analysed by robust, two-sided t-test (Welch-test).
    E.5.1.1Timepoint(s) of evaluation of this end point
    • Screening Phase: up to 28 days before treatment start
    • Treatment phase: 24 weeks ± 14 days including 8 weeks titration
    phase and 16 weeks continuation phase.
    • Safety follow-up: patient's well-being will be monitored by phone
    after 30 ± 7 days after last intake of study.
    • Survival follow-up: survival at study termination / last patient out
    E.5.2Secondary end point(s)
    Secondary parameters at baseline and during follow-up will be compared between groups comparing the difference between baseline and follow-up visits. Data will be displayed by means and standard deviations, medians and variances with respective 95% confidence intervals. p-values <0.05 will be considered as statistically significant.
    Secondary endpoints will be statistically analysed by a hierarchical testing strategy using the two-sided student’s t-test with comparison of the differences between riociguat (MK-4836) and placebo.
    It is assumed that WHO functional class will either remain the same, improve by one or two categories, or deteriorate by one category in most cases. A change score (baseline minus end of study) will be calculated, which could go from -3 (class IV at baseline and class I at end of study) to +4 (class I at baseline, death at end of study), but in practice for those patients still alive at the end of the study it will most likely range from -2 to +1.
    The safety analysis will be performed in the population valid for safety. All tabulations will be descriptive only.

    Riociguat (MK-4836) is not approved for the indications studied and therefore cannot be further prescribed after the end of the study. In case of development of manifest PAH, measured by RHC during Visit 3, a targeted PAH therapy will be initiated according to the guidelines. Otherwise the study medication will be discontinued. Patients will be offered a follow-up for 6 more months in terms of early detection any clinical deterioration.
