A randomized, double-blind, placebo-controlled, parallel group trial of HMR1766 assessing the efficacy and safety of 3 doses of HMR1766 (25, 100, 200 mg OD) versus placebo with cilostazol, 100 mg BID as a calibrator, administered for 26 weeks in patients with Peripheral Arterial Disease (PAD) Fontaine stage II. - ACCELA

入选标准

  • Inclusion criteria at screening period
  • Diagnosis of intermittent claudication (PAD Fontaine stage II):
  • 1. Patient with stable symptoms of intermittent claudication of the lower extremities, secondary to chronic occlusive arterial disease from atherosclerosis etiology (symptoms present for 6 months or longer and not significantly changed within the past 3 months);
  • 2. ICD (Initial claudication distance) of 30 to 250 m at screening constant workload treadmill test.
  • Confirmation of underlying PAD:
  • 3. Ankle/Brachial Index (ABI) of 0.90 to 0.5 or for patients with an ABI greater than 1.3 (due to non-compressible arteries), a Toe-Brachial Index (TBI) of less than 0.7.
  • Inclusion criteria at randomization
  • Confirmation of symptom stability:
  • 4. Mean ICD of 30 to 250 m calculated by averaging the constant workload treadmill test performed at the end of the run-in phase and the previous one performed at screening.
  • 5. The maximum change (measured in log) in the claudication distance should not exceed 0.25 between those two ICD measurements, as per international recommendation.
  • 6. The patient is not allowed to smoke 3 hours before treadmill / ABI tests.
  • Appropriate background therapy:
  • 7. The patients must have optimal cardiovascular risk prevention and appropriate management of PAD, including clopidogrel 75mg per day, during the study treatment period.
  • Are the trial subjects under 18? no
  • Number of subjects for this age range:
  • F.1.2 Adults (18-64 years) yes
  • F.1.2.1 Number of subjects for this age range
  • F.1.3 Elderly (>=65 years) yes
  • F.1.3.1 Number of subjects for this age range

排除标准

  • Exclusion criteria at screening / randomization visits
  • 1. Patient not having provided written informed consent.
  • 2. Patient participated in investigational clinical trials in the last 2 months prior screening.
  • 3. Pregnant or breast-feeding woman or woman without documented birth control measures for at least 3 months prior to randomization.
  • Potentially non-atherosclerotic and/or severe stage disease not amenable to medical therapy:
  • 4. Age below 40 years and/or onset of symptoms of PAD before the age of 40 years.
  • 5. Non-atherosclerotic peripheral arteriopathy (e.g. Buerger’s disease, aneurismal states, popliteal entrapment syndrome).
  • 6. Acute peripheral ischemia e.g. thrombosis in situ, trauma, paradoxical embolism of venous thrombi.
  • 7. Critical limb ischemia (equivalent to Fontaine stages III and IV), manifested by ischemic rest pain or trophic lesions.
  • Recent (within 3 months prior to screening) pharmacological treatment likely to interfere with study endpoints:
  • 8. Recent initiations or discontinuation of treatment by vasoactive agents (e.g. pentoxifylline, beraprost sodium, papaverine, isoxsuprine, nylidrin, cyclandelate and niacin derivatives). Patients treated by cilostazol within 3 months prior to screening will also be excluded.
  • 9. Concomitant treatment with sildenafil or other drug of the same class, from start of the run-in phase, until the end of the trial.
  • Recent (within 3 months prior to screening or during the run-in phase) changes in local and/or general conditions likely to interfere with study endpoints:
  • 10. Recent lower-extremity surgical or endovascular arterial reconstructions or sympathectomy, or recent deep venous thrombosis.
  • 11. Recent change in the level of compliance to supervised or unsupervised program of exercise training and smoking status.
  • 12. Recent occurrence of at least one of the following: acute myocardial infarction (MI), unstable angina (UA), coronary artery bypass graft (CABG), percutaneous coronary intervention (PCI), transient ischemic attack (TIA) or stroke; symptomatic cardiac arrhythmias or significant conduction disturbances.
  • Presence of medical and/or social conditions that would either interfere with participation in the trial, or lead to inability to complete the trial:
  • 13. Conditions other than claudication, limiting their exercise capacity, likely to jeopardize completion and/or safety of the treadmill testing, according to investigator’s judgment.
  • 14. Planned cardiac or vascular surgery or angioplasty or any major surgery within the next 6 months.
  • 15. Severe concomitant disease such that the patient is not expected to survive 6 months.
  • 16. Receipt of any investigational treatment (drug or device) within the previous 2 months.
  • 17. Inadequate control of hypercholesterolemia and diabetes mellitus.
  • 18. Geographic or social factors making study participation impractical.
  • Contra-indications to the use of clopidogrel, cilostazol, or conditions likely to affect
  • pharmacokinetics of cilostazol and/or comedication:
  • 19. Contra-indication to the use of clopidogrel.
  • 20. CHF of any severity.
  • 21. History of drug allergy to cilostazol or HMR1766.
  • 22. Severe hepatic disease (hepatic enzymes>3times ULN).
  • 23. Severe renal failure (serum creatinine greater than 2.5 mg/dL).
  • 24. Requirement for systemic administration of inhibitors of CYP3A4 such as ketoconazole, itraconazole, erythromycin, diltiazem, as well as substrates of CYP2C9 such as warfarin, fluvastatin.
