Sobi agreed to acquire Dova Pharmaceuticals for $27.50/share or approximately $915 million, with an additional $1.50/share CVR linked to FDA label expansion. Lead asset is Doptelet (avatrombopag) for thrombocytopenia in chronic liver disease and chronic ITP. Sobi completed the acquisition by merger on November 12, 2019. The CVR required FDA approval of Doptelet in chemotherapy-induced thrombocytopenia (CIT) by December 31, 2022; that approval was not obtained — the Phase 3 CIT trial reported in 2022 and avatrombopag remains approved only in chronic liver disease and chronic ITP — so the contingent $1.50/share milestone lapsed.

Did it work? Outcome assessment

Strategic verdict
Achieved Stated Rationale
Financial impact
Accretive
Sobi acquired Dova for up to ~US$915M (US$27.50/share cash plus a US$1.50/share CVR tied to a CIT approval), closing November 12, 2019. The acquired product Doptelet (avatrombopag) became a meaningful Sobi growth asset, generating SEK 3,870M (~US$370M) of revenue in full-year 2024. Sobi continued expanding the label (e.g., FDA approval for pediatric ITP in July 2025), indicating successful commercial integration and a return on the purchase price.
Pipeline outcome
Assets Advanced
Doptelet (avatrombopag) was advanced commercially and through label expansion. It remained approved for thrombocytopenia in chronic liver disease patients undergoing procedures and in chronic ITP; Sobi secured an FDA approval for pediatric persistent/chronic ITP in July 2025 following a December 2024 NDA acceptance, broadening the franchise.

Key facts

Disease & market context

Thrombocytopenia (Chronic Liver Disease and Chronic ITP)

$1.9B Evaluate peak sales projection for Doptelet across ITP+CLD

Disease Overview

Thrombocytopenia is a low platelet count that increases bleeding risk; in chronic liver disease (CLD) it complicates invasive procedures, while in chronic immune thrombocytopenia (ITP) the immune system destroys platelets. Both populations historically relied on platelet transfusions or first-generation TPO receptor agonists; oral once-daily TPO-RAs without dietary restrictions or hepatotoxicity warnings remain commercially attractive.

Competitive Landscape

The TPO receptor agonist class is led by Novartis' Promacta/Revolade (eltrombopag), an oral TPO-RA with a >$1.5B annual run rate but encumbered by food-related dietary restrictions and a hepatotoxicity warning. Amgen's Nplate (romiplostim) is a peptibody injection used in chronic ITP; Rigel's Tavalisse (fostamatinib, SYK inhibitor) launched in 2018 as a chronic-ITP option for refractory patients; rituximab and steroids remain off-label staples. Doptelet (avatrombopag) was FDA-approved in May 2018 for thrombocytopenia in CLD undergoing procedures and June 2019 for chronic ITP, differentiating on a cleaner clinical profile vs. Promacta — no dietary restrictions, no hepatotoxicity warning. By acquiring Dova for up to $915M ($27.50/share + $1.50 CVR tied to chemotherapy-induced thrombocytopenia/CIT approval), Sobi gained a US hematology callpoint adjacent to its Synagis/Kineret/Gamifant franchise, with Evaluate projecting $1.88B peak across approved indications. However, BioPharma Dive noted Q2 2019 Doptelet sales of $3.5M missed Wall Street's $5.6M, with Jefferies' Eun Yang flagging payer restrictions.
