Alfasigma USA Acquires ZELNORMTM (tegaserod) for Reintroduction to the US Market
Alfasigma USA has acquired the brand ZELNORM (tegaserod), a treatment for IBS-C, from Sloan Pharma
In March 2019, ZELNORM was approved for reintroduction by the FDA for the treatment of adult women less than 65 years of age with IBS-C.
Alfasigma USA plans to relaunch the brand in the United States, making ZELNORM available by prescription in the coming weeks.

The US Food and Drug Administration (FDA) has approved the reintroduction of tegaserod oral tablets (Zelnorm, Sloan Pharma) for irritable bowel syndrome with constipation (IBS-C) in women younger than age 65, US WorldMeds Holdings has announced.
"We are excited about what the reintroduction of Zelnorm means for patients suffering from irritable bowel syndrome with constipation. We have continually heard from patients and clinicians alike that the IBS-C community is eager to have Zelnorm return to the US a s an available treatment option," P. Breckinridge Jones, CEO of US WorldMeds, said in the news release.
"The re-approval of Zelnorm is very good news for patients. We believe it will provide renewed access to a treatment option where other new medications have been insufficient for meeting patients' needs," added Jeffery Roberts, patient advocate and founder of the IBS Patient Group.
Tegaserod for IBS-C has had a checkered past. The drug was first approved by the FDA in 2002 for the short-term treatment of women with IBS-C. It was suspended from the US market in March 2007 due to potential cardiovascular (CV) safety concerns.
In July 2007, the FDA announced that it would allow restricted use of the drug for IBS-C and chronic idiopathic constipation in women younger than 55 years with no history of heart problems.
Last October, following a safety review, the FDA's Gastrointestinal Drugs Advisory Committee (GIDAC) recommended overwhelmingly (11 yes, 1 no) to recommend reintroducing tegaserod for IBS-C in women without a history of CV ischemic disease and who have no more than one risk factor for CV disease.
The committee reviewed clinical data from 29 placebo-controlled trials and newly-available sources of treatment outcome data.
Pooled data from the clinical trials showed a statistically nonsignificant trend toward increased angina among those who took the drug in the clinical trial on which the drug's approval was based in 2002; however, a recent analysis of 18,000 participants in the entire clinical database found adverse CV events in 13 of 11,614 patients (0.11%) taking tegaserod, compared with only one patient (0.01%) out of 7031 in the placebo group, a difference that was statistically significant, according to information in an FDA briefing document for the committee.
"While an imbalance in CV safety events associated with tegaserod was noted, the strength of the signal was difficult to interpret due to limitations of the meta-analysis â€" for example, the trials were not designed to specifically evaluate CV safety, were of short duration, included a low CV-risk population, and involved retrospective assessment of CV information. In addition, the etiology of [CV ischemic] events related to the use of tegaserod is not well understood," the FDA explained in the briefing document.
Tegaserod is the only selective serotonin-4 (5-HT4) receptor agonist approved to treat IBS-C, US WorldMeds notes in the release.
In clinical trials, patients taking tegaserod experienced improvement in some of the most bothersome IBS-C symptoms; in the first 4 weeks, significantly more tegaserod-treated patients than placebo-treated patients reported an improvement in abdominal pain/discomfort and bloating. The frequency of bowel movements also increased from a median number of 3.8 per week at baseline to 6.3 per week at month 1, the company said.
Zelnorm will be available by prescription for patients in the coming months, according to the company.
