Admitted to hospital for a suspected or confirmed diagnosis of CAP defined by radiographic evidence of new or worsening infiltrate and one or more of the following signs and/or symptoms of lower respiratory tract infection
Requires supplemental oxygen to treat hypoxemia (or requires an increased level of supplemental oxygen if on chronic oxygen therapy)
Timeline
Screening 3 weeks
Treatment Varies
Follow Up 30 days, 90 days, and 180 days

ATTACC-CAP Trial Summary
This trial will compare the effects of heparin to usual care on outcomes for people admitted to hospital with pneumonia.
Who is the study for?
Adults hospitalized with community-acquired pneumonia (CAP) needing oxygen, expected to stay at least 72 hours post-randomization. They must have a primary diagnosis of CAP with new or worsening lung infiltrates and symptoms of lower respiratory infection. Excluded are those admitted over 72 hours, on chronic ventilation, not using thromboprophylaxis, needing full anticoagulation for other reasons, suspected COVID-19, in ICU on life support measures at enrollment time, or with bleeding risks.Check my eligibility
What is being tested?
The trial is testing if therapeutic-dose heparin improves outcomes compared to standard care in hospitalized patients with CAP. It's an international study where participants are randomly assigned to receive either heparin or usual care and the results will be evaluated adaptively as they come in.See study design
What are the potential side effects?
Heparin can cause bleeding problems including bruising easily and prolonged bleeding from cuts. Some may experience allergic reactions like rashes or itching. Rarely it can lead to a drop in platelets causing clotting issues known as HIT (heparin-induced thrombocytopenia).

Experimental Treatment
Active Control
Group I: Therapeutic-Dose HeparinExperimental Treatment1 Intervention
Participants randomized to the investigational arm will receive a pragmatic strategy of therapeutic-dose low molecular-weight heparin (LMWH) or unfractionated heparin (UFH) administered daily for up to 14 days or until hospital discharge, whichever occurs first. Participants should start receiving study drug as soon as possible following randomization.
Group II: Usual CareActive Control1 Intervention
Participants randomized to the control arm will receive usual care thromboprophylactic dose anticoagulation according to local practice. To ensure adequate separation between the study groups, the dose of heparin/LMWH used in the usual care arm should not equal more than half of the approved therapeutic dose for that agent according to local VTE treatment protocols.
