Biopharmaceutical company Actelion Ltd. said Friday that it had been approached by Johnson & Johnson about a possible deal.
Shares rose 16% to 182.40 Swiss francs on the SIX Swiss Exchange.
J&J didn't immediately respond to a request for comment.
Last year, Switzerland-based Actelion reported revenue of 2.05 billion francs ($2.02 billion) and a profit of 551.9 million francs.
Actelion, which had its initial public offering at the turn of the century, focuses on drugs for pulmonary arterial hypertension, a type of high blood pressure that affects arteries in the lungs and in the heart.
Bloomberg reported Thursday that J&J had made an initial bid for the specialty drug company.
Shares of J&J rose 0.7% to $113.88 in morning trading in the U.S.
