Our Pipeline

Clinical Studies

We are currently conducting six international clinical research studies; two Phase 3 studies with linzagolix in women with heavy menstrual bleeding associated with uterine fibroids (PRIMROSE 1 & 2),  two Phase 3 studies with linzagolix in women with endometriosis-associated pain (EDELWEISS 2 & 3), one Phase 3 study with nolasiban in women undergoing IVF (IMPLANT 4) and one clinical Phase 2a study with OBE022 in preterm labour (PROLONG).

Primrose 1 & 2: Heavy Menstrual Bleeding due to Uterine Fibroids

Primrose 1 & 2 are clinical research studies evaluating linzagolix in women with heavy menstrual bleeding due to uterine fibroids. Each study is treating women with either 100 mg, 200 mg of linzagolix once daily with or without add-back therapy or placebo for 24 to 52 weeks.

What is a Clinical Research study?

A Clinical research study (also called a clinical trial) is a medical study conducted with patient volunteers, that helps to answer important questions about an investigational medication, such as: does it work? All medications must be tested in Clinical research studies before they can be approved to be prescribed to patients. Without people taking part in these studies, we would have no new medications.
