Overview
Brief Summary
Objectives
Primary Objectives:
- Pilot Study: A preliminary assessment of the exposure and safety of oral A-60444 in post-stem cell transplant patients with RSV infection.
- Main Study: To determine the antiviral effect of oral A-60444 versus placebo in post-stem cell transplant patients with RSV infection and to assess the safety of oral A-60444 in post-stem cell transplant patients with RSV infection.
Secondary Objectives:
- To study the pharmacokinetics of A-60444 in the presence of concomitant medications such as immunosuppressants and antifungals, in post-stem cell transplant patients with RSV infection.
Sample Size: Six patients will be included in the open, pilot phase of the study and there is an option to include a further 22 patients into the main, placebo-controlled study, depending on the pilot study findings. An independent Data Safety Monitoring Board will assess the findings of the pilot study.
Detailed Description
Clinical will be recorded daily. A-60444 PK will be studied pre-dose and at peak dose on the last day (Day 5) of dosing.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Patients diagnosed with RSV infection who have had a stem cell transplant.
- •Female patients must be of non-childbearing potential or have a negative pregnancy test prior to study start and be deemed not at risk of becoming pregnant. Females of non-childbearing potential are defined as women who have had a hysterectomy, bilateral oophorectomy, tubal ligation, or who have been post-menopausal for at least two years; or are considered to be sterile due to recent chemotherapy.
- •Aged between 18 and 65 years.
- •Patients who have given their written informed consent to participate in the study.
- •Patients who are willing and able to comply with the protocol and study procedures.
Exclusion Criteria
- •Patients who have received an investigational drug within one month preceding the start of dosing.
- •Patients who have a documented history of allergy to benzodiazepines.
- •Patients with significant hepatic impairment (alanine transaminase \[ALT\] more than 5 x upper level of normal \[ULN\], total bilirubin more than 3 x ULN). Biochemistry data collected four weeks prior to screening is acceptable.
- •Patients, who in the opinion of their general practitioner or the Investigator, should not participate in the study.
Outcomes
Primary Outcomes
Reduction of viral load over time:
2-log reduction (by quantitative real time reverse transcription polymerase chain reaction [rtRT PCR]) in the RSV load of nasopharyngeal swabs in patients three days after treatment with A-60444, compared to patients treated with placebo
Secondary Outcomes
- Change in viral titre over treatment period
- Safety, pharmacokinetics (PK)
