XC8 in the Treatment of Patients With Bronchial Asthma

• Status: Completed
• Trial end date: 2017-09-27
• Target enrollment: 0
• Participant gender: All

Summary

A multicenter, double-blind, randomized, parallel-group comparative Phase II clinical study to assess the efficacy and safety of different doses of XC8 vs Placebo in patients with partly controlled bronchial asthma receiving stable treatment with low doses of inhaled corticosteroids with or without long-acting beta2-agonists during 12-weeks treatment period.

Study design was developed by Pharmenterprises LLS, Russia in cooperation with Eurrus Biotech GmbH, Austria and FGK Clinical Research GmbH, Germany.

The primary objective of the study was to evaluate the effect of different doses of XC8 on change in pre-bronchodilator forced expiratory volume in 1 second (FEV1) (% of predicted value) at Week 12 as compared to baseline at Week 0 vs. Placebo in patients with partly controlled bronchial asthma (BA).

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Criteria

Inclusion Criteria:

1. Signed the informed consent.

2. Non-smoking men and women aged from 18 to 65 (inclusively).

3. Diagnosis of bronchial asthma that was established not later than 12 months before screening (with mandatory documented evaluation of reversibility of bronchial obstruction assessed by pre- and post-bronchodilator spirometry).

4. Stable therapy with low doses of inhaled corticosteroids with or without long-acting beta2-agonists for at least 3 months prior to screening (Step 2 and 3 according to GINA, 2015 guideline)

5. Symptoms of partly controlled bronchial asthma during four weeks before screening (accordingly to GINA, 2015)

6. Pre-bronchodilator FEV1 is 60-80% of predicted values (inclusive) *

7. Consent of patient to use adequate methods of contraception throughout the study. The adequate methods of contraception are as follows:

• Oral or transdermal contraceptives;

• Condom or diaphragm (barrier method) with spermicide, or

• Intrauterine device.

8. Ability to follow all the requirements of the protocol

Exclusion Criteria:

2. Smoking within 1 year prior to screening; smoking history of more than 10 pack-year

3. Severe exacerbations or not controlled bronchial asthma for 3 months before screening

4. Chronic Obstructive Pulmonary Disease (COPD) or other lung diseases in addition to bronchial asthma.

5. Inflammatory diseases of mouth

6. Acute infection within 30 days of screening

7. Participation in any clinical trial or use of any investigational product within 30 days of screening

8. Use or indication to take other drugs for treatment of asthma (including antileukotrienes and theophylline extended release), except those permitted by the Protocol

9. Indication for long-term administration of systemic steroidal or non-steroidal anti-inflammatory agents or agents affecting the immune system

10. The need of periodical administration of antihistamines (stable doses of antihistamines for at least 1 month prior to screening and throughout the trial is allowed)

11. Administration of immunosuppressant drugs within 3 months before screening

12. Anaphylaxis, generalized urticaria or angioedema within 1 year prior to screening

13. Known allergy, hypersensitivity or contraindication to receiving XC8 or its components

14. Systemic autoimmune diseases or collagen vascular disease in history.

15. History of malignancy within the past 5 years (except for basal cell carcinoma)

16. Significant cardiac and vascular disease at the present time or for 12 months before screening, including chronic heart failure NYHA Class III or IV; severe arrhythmia requiring therapy with Class Ia, Ib, Ic and Class III antiarrhythmic drug; unstable angina; myocardial infarction; cardiac surgery and CABG; relevant cardiac valves disorders; transient ischemic attack or stroke; uncontrolled arterial hypertension with systolic pressure >180 mm Hg and diastolic pressure >110 mm Hg; pulmonary embolism or deep vein thrombosis.

17. Nephrotic syndrome, moderate and severe chronic renal failure, or significant renal diseases with creatinine level of >1.5 mg/dL (132 μmol/L) in men and >1.4 mg/dL (123 μmol/L) in women or Glomerular Filtration Rate (GFR) < 60 ml/min.

18. HIV, hepatitis B or C, hepatic cirrhosis in history; elevated level of serum aspartate aminotransferase (ASAT) or alanine aminotransferase (ALAT) ≥ 3 times of the upper limit of normal (UNL); elevated common bilirubin ≥ 2 times of UNL at the screening.

19. Anemia (hemoglobin ≤10.5 g/dL in women and ≤ 11.5 g/dL in men); marked blood loss or sampling not less than one unit of donated blood (≥ 500 ml) or blood transfusion for previous 12 weeks.

20. Any concomitant disease besides bronchial asthma which is not controlled with stable treatment.

21. Drug or alcohol abuse at the moment of screening or in past which, at the discretion of the investigator, make the patient unfit for the study

22. Inability to read or to write; unwillingness to understand and to follow the procedures of the study protocol; violation of the drug administration regimen or procedure execution that, at the discretion of the Investigator, can impact the results of the study or safety of the patient and interfere his further participation in the study; any other concomitant medical and serious mental conditions which make the patient unfit for participation in the clinical study, limit a validity of receiving of informed consent or can affect ability of the patient to take part in the study
