SAN DIEGO--([ BUSINESS WIRE ])--Shareholder Rights Law Firm [ Johnson & Weaver, LLP ] announces it is investigating whether certain officers and directors of Vertex Pharmaceuticals Inc. (NASDAQ: VRTX) breached their fiduciary duties to the company and violated federal securities laws by making false and misleading statements about the results of clinical trials for drugs related to the treatment of Cystic Fibrosis (aCFa). Specifically, on May 7, 2012, Vertex issued a press release claiming that the CF patients who received two of its drugs during clinical trials showed significant improvement in their lung functions. On this news, Vertexas stock price jumped from $37.41 per share to $58.12 per share. Between May 7 and May 25, certain officers and directors sold over $22 million of their personally owned shares. Beginning on May 29, however, Vertex issued a series of press releases in which it admitted that the results from its clinical trials were not as positive as previously indicated. On this news, Vertexas stock price dropped from a high of $64.85 to a low of $51.18. Notably, Senator Charles Grassley has sent a letter to the SECas chairwoman asking her to probe into whether Vertexas officers and directors illegally profited from improper stock sales. According to Senator Grassley, a[i]t could appear that these . . . executives potentially took advantage of the spike in the stock knowing the news of the clinical data being overstated would be made public eventually, which in turn would negatively affect the stock value.a
