Key result

Avatrombopag sustains platelet response for ~12 weeks in ITP and cuts transfusions in chronic liver disease.

  • P<0.0001

Why the study?

Does avatrombopag improve platelet response and reduce the need for platelet transfusions or rescue procedures in adult patients with chronic ITP or CLD?

Population

Adult patients with chronic ITP or chronic liver disease scheduled for an invasive procedure

Comparison

Avatrombopag vs placebo

Design

Narrative review of phase III clinical trials

Overview

Supports avatrombopag as oral option for refractory ITP and periprocedural CLD thrombocytopenia; extends TPO-RA class evidence to second-generation agents.

Structured PICO

Does avatrombopag improve platelet response and reduce the need for platelet transfusions or rescue procedures in adult patients with chronic ITP or CLD?

P
Population
A review of clinical evidence for avatrombopag in adult patients with chronic immune thrombocytopenia and thrombocytopenia associated with chronic liver disease.
I
Intervention
Avatrombopag (orally administered second generation thrombopoietin receptor agonist)
C
Comparator
Placebo (in the context of the discussed phase III studies)
O
Outcome
Platelet response (in ITP) and requirement for platelet transfusion or rescue procedures for bleeding caused by surgery (in CLD)surrogate

Main Result

Absolute Event Rate: 12% vs 0.1%

p-value: p=<0.0001

Avatrombopag is an effective oral treatment for increasing platelet counts in chronic ITP and preventing bleeding events in CLD patients undergoing invasive procedures.

Limitations

  • Lack of completed head-to-head trials against active comparators like eltrombopag or lusutrombopag
  • Potential risk of thromboembolic events and bone marrow reticulin fibrosis with long-term use

Cite This Study

Anthony Markham (2021) conducted a review in Thrombocytopenia (chronic ITP and CLD). Avatrombopag vs. Placebo was evaluated on Cumulative mean number of weeks of platelet response without needing rescue therapy (ITP trial) (p=<0.0001). Avatrombopag significantly increased the cumulative weeks of platelet response in chronic ITP (12 vs 0.1 weeks) and reduced the need for platelet transfusions in patients with chronic liver disease compared to placebo.
