Effects of RP101 in Post-menopausal Women With Dry Eye Syndrome


Brief description of study

The main purpose of this study is to establish whether RP101 can reduce symptoms of dry eye syndrome in post-menopausal women.

Detailed Study Description

Redwood Pharma is developing the novel ophthalmic product RP101 containing the known active substance 17-oestradiol-3-phosphate and based upon the drug delivery platform IntelliGel which controls the active substance release. The novel formulation is planned to meet the still unmet medical need of an efficacious treatment against chronic dry eye in postmenopausal women.

The efficacy of the novel formulation RP101 will be investigated for the first time in the present multicentre, randomised, double-masked, parallel-group, placebo-controlled Phase II study in women post-menopausal for at least 3 years presenting with symptoms specific for dry eye syndrome of moderate to severe intensity.

The planned study will be conducted in Austria, Germany and Hungary. The primary objective of the study is to establish the effective dose/dose regimen of RP101 in these patients applying RP101 ophthalmic sterile solution or matching placebo (vehicle) once (q.d.) or twice a day (b.i.d.) for 3 months. One hundred (100) patients will be enrolled in this study. The subjects will be randomly assigned (1:1:1:1) to a treatment group and will receive one of the treatments for 90 consecutive days.

Evaluation of the clinical efficacy during and at the end of the treatment will be done on the basis of the Schirmer's test type II (with anaesthesia).

The secondary objectives of the study are:

  • to evaluate the safety and tolerability of the treatment
  • to evaluate the pharmacokinetics (PK) of serum 17-oestradiol after the 1st and the last dose (only PK substudy).
