Details and patient eligibility

About

To evaluate the safety and tolerability of S-1226 composed of perflubron with ascending doses of carbon dioxide (4%, 8%, and 12% CO2) administered over 2 minute nebulisation to healthy subjects.

Full description

There will be up to 3 cohorts (1 cohort per dose level). Each cohort will include 12 subjects (9 receiving S-1226 and 3 receiving matching placebo). For each dose level, a sentinel group of 2 subjects will be dosed (1 subject with S-1226, 1 subject with placebo) 24 hours prior to dosing the rest of the study population.

It may be necessary to repeat, or modify (decrease) a dose level, and thus an additional cohort of up to 12 subjects may be enrolled.

Enrollment: 36 patients

Sex: All

Ages: 18 to 55 years old

Volunteers: Accepts Healthy Volunteers

   • the absence of clinically significant findings on a chest X-Ray at screening.

3. Steroid-naive (i.e. volunteers who are not currently on topical or systemic corticosteroids or those who have not taken any oral or injectable corticosteroid within 60 days prior to study drug administration or have not used any inhaled/ophthalmic/nasal corticosteroid within 30 days prior to study drug administration).

4. Females of childbearing potential who are sexually active with male partner must be willing to use one of the following acceptable contraceptive methods throughout the study and for 30 days after:

   • simultaneous use of intra-uterine contraceptive device without hormone release system placed at least 4 weeks prior to study drug administration, and for the male partner, condom;
   • simultaneous use of diaphragm and for the male partner, male condom and spermicide starting at least 14 days prior to study drug administration;
   • simultaneous use of female condom starting at least 14 days prior to study drug administration, and for the male partner, condom and spermicide;
   • sterile male partner (vasectomized since at least 6 months).

5. Males subjects who are not vasectomized for more than 6 months, and who are sexually active with non-sterile female partner must be willing to use one of the following acceptable contraceptive methods throughout the study and for 30 days after:

   • simultaneous use of condom, and for the female partner, oral contraceptive, or intra-uterine contraceptive device placed at least 4 weeks prior to study drug administration;
   • simultaneous use of male condom, and for the female partner, diaphragm and spermicide ;
   • simultaneous use of male condom, and for the female partner, female condom and spermicide ;
   • Sterile female partners include post-menopausal women (absence of menses for 12 months prior to drug administration) or women who have had a tubal ligation, hysterectomy, or bilateral oophorectomy (at least 6 months prior to drug administration).

6. Capable of consent.

7. Subjects must have a normal lung function (FEV1 ≥ 80 % of predicted and FEV1/FVC > 70 %).
