Synergy Pharmaceuticals Inc. (NASDAQ:SGYP), today reported its financial results and business update for the three and six months ended June 30, 2014.
Key Development Highlights:
- On April 28, 2014, we announced the start of our second pivotal phase 3 clinical trial to confirm the safety and efficacy of plecanatide, our lead uroguanylin analog and once-daily oral tablet, in adult patients with chronic idiopathic constipation (CIC). This study is running in parallel with the first pivotal phase 3 CIC trial that was initiated in November 2013 and achieved the halfway mark for total enrollment on July 14, 2014. The CIC registration program includes two randomized, double-blind clinical trials to compare a 12-week regimen of plecanatide (3.0 and 6.0 mg) versus placebo in adult patients with CIC. The primary endpoint for the two pivotal trials is the proportion of patients who are overall responders for the 12-week treatment period. An overall responder for CIC is defined as a weekly responder for at least 9 out of the 12 treatment weeks, including at least 3 of the last 4 weeks. A weekly responder is defined as a patient who has ≥ 3 CSBMs per week and an increase from baseline of ≥ 1 CSBM for that week. Top-line data for the first CIC pivotal trial is expected in the second quarter of 2015.
- On April 30, 2014, we announced positive top-line results from our phase 2b dose-ranging study assessing the efficacy and safety of plecanatide (0.3, 1.0, 3.0 and 9.0 mg) versus placebo in adult patients with irritable bowel syndrome with constipation (IBS-C). Plecanatide 1.0, 3.0 and 9.0 mg doses demonstrated statistically significant improvement in the study’s primary endpoint – complete spontaneous bowel movement (CSBM) frequency- and was safe and well tolerated at all doses. Notably, patients taking the plecanatide 3.0 mg dose consistently experienced statistically significant improvement in key secondary endpoints, including change from baseline versus placebo in worst abdominal pain intensity, stool consistency (BSFS) and met the overall responder endpoint for the 12-week treatment. An overall responder for IBS-C fulfills both ≥30% reduction in worst abdominal pain and an increase of ≥1 CSBMs from baseline in the same week for at least 50% of the weeks (i.e., 6/12 weeks). The overall responder endpoint is the FDA endpoint required for U.S. approval in IBS-C. In addition, patients taking plecanatide 3.0 mg experienced a <10% diarrhea rate.
- On July 8, 2014, we announced a successful End-of-Phase 2 meeting with the FDA and that agreement was reached on the plecanatide pivotal phase 3 IBS-C clinical development plan and primary endpoint for registration trials. The pivotal phase 3 IBS-C program is scheduled to begin in the fourth quarter of this year and will include two trials to evaluate the efficacy and safety of plecanatide 3.0 and 6.0 mg doses, consistent with the ongoing CIC registration trials. IBS-C patients successfully completing either of the 12-week placebo-controlled registration trials will be offered enrollment into a long-term safety trial in order to support the ongoing long-term safety database for the CIC indication.
- On July 17, 2014, we announced the successful completion of patient enrollment for our phase 2 trial of SP-333, our next-generation uroguanylin analog, in adult patients with opioid-induced constipation (OIC). This multi-center, randomized, double-blind clinical trial is designed to compare a 4-week, dose-ranging regimen of once-daily oral SP-333 (1.0, 3.0 and 6.0 mg) versus placebo in patients taking opioid analgesics for chronic, non-cancer pain for at least three months. The primary endpoint of the study is mean change from baseline in the number of SBMs during week 4 of the treatment period. Top-line data for this trial is expected in the fourth quarter of this year.
- On August 7, 2014, we learned that our request to the FDA for a waiver of the requirement to conduct a thorough QT study with plecanatide had been granted.
“We are pleased with the clinical milestones achieved over the last several months along with the positive interactions with the FDA,” said Dr. Gary S. Jacob, Chairman and CEO of Synergy. “We remain focused on the successful execution of our clinical programs as we enter the second half of this year and look to start our second registration program with plecanatide in IBS-C and continue to advance the ongoing pivotal phase 3 CIC trials toward our anticipated NDA filing next year.”
