This is a proof-of-concept study in 2 parts.
In Part A, patients will receive OBE022 open-label in order to assess the safety and pharmacokinetics in pregnant women with spontaneous preterm labour with a gestational age between 28 0/7 and 33 6/7 weeks.
Part B has a double-blind, randomised, placebo controlled, parallel group and multicentre design and will assess the efficacy, safety and pharmacokinetics in pregnant women with threatened spontaneous preterm labour with a gestational age between 24 0/7 and 33 6/7 weeks.
All patients in part A and part B must receive atosiban infusion for 48 hours as standard of care treatment. Patients from Part A will receive OBE022 open label. Patients from Part B will be randomised to receive OBE022 or matching placebo. IMP treatment duration will be up to 7 days. IMP treatment will be stopped in case of delivery prior to Day 7.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Active | Experimental | OBE022 plus atosiban: OBE022 will be given orally from Day 1 to Day 7. OBE022 treatment will be initiated ideally simultaneously or at a maximum within 24 h after atosiban start.
Atosiban will be administered over 48h as per label. |
|
| Placebo | Active Comparator | OBE022 matching placebo plus atosiban: OBE022 matching placebo administration will follow the same regimen as the active group. Atosiban will be administered over 48h as per label. |

| Apgar score. | The score is a rapid method for assessing a neonate immediately after birth. Elements of the Apgar score include color, heart rate, reflexes, muscle tone, and respiration, each weighted evenly and assigned a value of 0, 1, or 2. The components are then added together to give a total score (0 to 10) that is recorded at 1 and 5 minutes after birth. | At birth, at 1 minute and 5 minute |

The ASQ-3 covers five areas of child development that includes: personal social, gross motor, fine motor, problem solving, and communication. Parents complete the questionnaire independent of professionals, indicating for each item "yes" if child performs the item, "sometimes" indicating an occasional or emerging skill, or "not yet" indicating that the child does not yet perform the behavior | Up to 24 months |
