Liquidia surges as United Therapeutics settlement removes key litigation risk

Oct 14 (Reuters) – Liquidia shares jumped nearly 37% in premarket trading on Wednesday after the drugmaker settled a years-long legal dispute with United Therapeutics over its lung disease ​drug.

The settlement, announced late on Tuesday, ends six lawsuits ‌over patents, trade secrets, contracts and antitrust claims related to Liquidia’s Yutrepia, an inhaled dry-powder form of the drug treprostinil.

Yutrepia is approved to treat pulmonary arterial hypertension (PAH) and pulmonary hypertension linked to interstitial lung disease (PH-ILD), and competes ‌in ​the market with United Therapeutics’ Tyvaso.

As part ⁠of the settlement, Liquidia will ⁠stop promoting its drug for PH-ILD, but will keep selling it for PAH. It will also pay United Therapeutics about $380.7 million in installments through 2027.

“We expect to fund the outlined ​payments from the ongoing sales of Yutrepia and cash on hand,” Chief Financial Officer Michael Kaseta said.

The deal removes a ⁠major legal risk for Liquidia, whose ⁠shares had lost more than half their value after ​an adverse court ruling last month, while narrowing the competition for ​United Therapeutics’ Tyvaso.

“With the legal overhang removed, we now ‌view Liquidia primarily as a Yutrepia growth story in PAH, with upside from label expansion plus significant pipeline opportunities from L606,” Jefferies analyst Manoj Eradath said.

L606 is Liquidia’s experimental lung disease drug, ⁠currently in late-stage development.

Liquidia will not appeal the ruling and has asked the US Food and Drug Administration to remove PH-ILD from Yutrepia’s label, ⁠the drugmaker said.

J.P. ‌Morgan analyst Jessica Fye said while the outcome ⁠was on par with investor expectations, the ​roughly $380 million ‌payment was “better than expected” for United Therapeutics.

The settlement ​would likely ⁠improve visibility into future Tyvaso growth in PH-ILD, Jefferies analyst Roger Song said.

United Therapeutics said in a regulatory filing that Liquidia would terminate trial cohorts studying PH-ILD and cease publication of related data as part of the settlement.
