Shares of

In a

from June 13, GlaxoSmithKline announced the results from the “Phase III PETIT2 study evaluating the efficacy of eltrombopag vs. placebo in paediatric patients with chronic immune (idiopathic) thrombocytopenic purpura (cITP).” Eltrombopag, known as Promacta in the U.S. and Revolade in Europe and other countries, met the primary endpoint in the study. The results showed a “statistically significant improvement in platelet counts with almost 40 percent of patients treated with eltrombopag attaining a consistent platelet response for 6 of 8 weeks compared to placebo (39.7 percent vs. 3.4 percent, respectively, p<0.001).” “The PETIT2 study results presented today show an increase in platelet response rate with eltrombopag treatment— an important result given that these children had failed other standard therapies,” said Dr. Rafael Amado, Head of Oncology R&D, GlaxoSmithKline. “We look forward to continuing to assess the potential of eltrombopag in these patients and to moving forward with planned regulatory submissions for a paediatric indication in cITP later this year.”

The financial media outlet noted 100 percent downside for shares of Ligand.

highlighted three main points in its article on Monday:

The article cited Lemelson Capital Management's concern regarding the biotechnology company. The firm wrote, “Ligand's press releases and communications with investors paint an exceedingly optimistic picture of the Company's future growth. Yet the firm's SEC filings reveal a business whose key revenue streams are either in decline, or are likely to diminish entirely. By way of example, collaborative R & D revenues (a substantial part of Ligand's overall sales and business model), have already declined 79 percent in just the last four years, further concentrating the Company's business into just two precariously remaining fragile revenue streams.”

Following Seeking Alpha's report, Roth Capital called the claims “foolish.” The analyst believes the data from the Glaxo's press release should support approval of the drug in pediatric patients with cITP. Roth Capital reiterated a Buy rating and $92.00 price target on Ligand Pharmaceuticals.
