Brief Summary:
This study is intended to assess the ability of AZD3427 to reduce pulmonary vascular resistance (PVR) after 24 weeks of treatment in participants with heart failure (HF) and pulmonary hypertension (PH) Group 2

Condition or disease Intervention/treatment Phase
Pulmonary Hypertension (World Health Organization Group 2) Heart Failure Drug: AZD3427 Drug: Placebo Phase 2

Detailed Description:

This study is a randomized, placebo-controlled, multi-centre, dose-ranging study of AZD3427 in participants with heart failure and pulmonary hypertension due to left heart disease (World Health Organisation [WHO] Group 2).

Approximately 220 participants will be randomised to 4 treatment groups (in a 1:1:1:1 ratio) to receive a subcutaneous (SC) injection of AZD3427 or placebo every 2 weeks for 24 weeks.

This study will evaluate 3 dose levels of AZD3427: Dose A, Dose B, and Dose C. Dose modification is not applicable for this study.

The study will be conducted in approximately 60 study centres across an estimated 15 countries.

The study will include approximately 16 study visits: 2 visits during the Screening Period,13 visits during the Treatment Period, and one visit during the Follow-up Period.

The expected total duration of the study is 32 to 37 weeks, depending on the length of the Screening Period.
