LUGANO, Switzerland, May 4, 2016 /PRNewswire/ --
- In the Trial, Elsiglutide Reduced the Incidence of Chemotherapy-induced Diarrhea in Colorectal Cancer Patients Receiving 5-FU Based Chemotherapy Regimens, but not Sufficiently to Meet the Primary Endpoint for Statistical Significance
- Elsiglutide was Observed to be Safe and Well Tolerated in This Patient Population
- Helsinn is Working on Potential Development Options for Elsiglutide to be Decided Following a Full Evaluation of the Phase IIb Data Set
Helsinn, the Swiss pharmaceutical Group focused on building quality cancer care, announces top-line results from its clinical Phase IIb dose-finding trial to assess the efficacy of elsiglutide in the prevention of diarrhea induced by chemotherapy in patients with colorectal cancer. The results showed a positive numerical but not statistically significant effect of elsiglutide on the primary endpoint, defined as the proportion of patients experiencing a maximum grade ≥ 2 diarrhea during the first cycle of chemotherapy. In the trial, elsiglutide demonstrated a favorable safety and tolerability profile.
Elsiglutide is a novel GLP-2 analogue invented by Zealand. Global development and commercialization rights to the compound are licensed to Helsinn for its therapeutic use in the field of cancer supportive care. Results from a previous clinical Phase IIa trial conducted by Helsinn have shown that elsiglutide reduces the severity of chemotherapy-induced diarrhea (CID) in colorectal cancer patients with a good safety profile. Diarrhea is one of the most debilitating side effects associated with cancer treatment and in particular chemotherapeutic agents containing 5-Fluorouracil (5-FU). No effective approved treatment for chemotherapy-induced diarrhea exists today.
Riccardo Braglia, Helsinn Group Vice-Chairman and CEO, commented on the results:
"Obviously we are truly disappointed with the primary outcome of this trial and our team will now thoroughly analyse all the trial results. We will then evaluate the best path forward for this program, while acting, as we always do at Helsinn, in the best interest of patients and with our focus on improving the everyday lives of cancer patients."
The Phase IIb trial with elsiglutide was conducted at 45 centers across five EU countries (Germany, Czech Republic, Hungary, Poland and Bulgaria), Belarus, Russia and Ukraine and included a total of 497 colorectal cancer patients treated with 5-FU based chemotherapy (FOLFOX or FOLFIRI). Of the total number of patients, 13 received additional treatment with a monoclonal antibody and were not included in the primary trial population. All patients in the trial were randomized to treatment with one of three doses of elsiglutide (10 mg, 20 mg, or 40 mg) or placebo, administered subcutaneously once-daily over four consecutive days in the first two chemotherapy cycles. All patients were followed for three cycles.
Helsinn is working on potential options for the further development of elsiglutide. The company will evaluate the full set of data generated from the Phase IIb trial and discuss the results with medical experts with the objective of fully understanding the outcome for elsiglutide and evaluate next possible steps.
About chemotherapy-induced diarrhea (CID)
Diarrhea is one of the most debilitating side effects associated with cancer treatment. CID is associated with weight loss, malnutrition, fatigue, loss of fluids and electrolytes imbalance that, in case of persistent and severe diarrhea, can result in life-threatening dehydration, renal insufficiency, and may contribute to cardiovascular morbidity. The incidence and severity of CID varies considerably with the nature and dose of the cytotoxic therapy and frequencies. A high incidence of diarrhea of any grade (between 30-80%) has been reported in colorectal cancer patients receiving chemotherapeutic agents containing 5- Fluorouracil (5-FU) alone or in combination with oxaliplatin or irinotecan. Other chemotherapeutic agents commonly administered to patients with lung, breast or neuroendocrine cancers may cause diarrhea to a lesser extent.
The occurrence of CID has a potential negative impact on the compliance of patients with their chemotherapy regimens and schedules, which can result in a delay in therapy, dosage reduction or discontinuation of therapy. Changes to chemotherapy treatment resulting from CID may ultimately affect the patient's clinical outcome, and impact on overall health care resource consumption. The occurrence of CID can significantly impair patients' quality of life.
Elsiglutide is a novel, potent and selective GLP-2 analogue invented by Zealand for the prevention of chemotherapy-induced diarrhea (CID). GLP-2 is a native peptide, secreted upon ingestion. It plays a key role in intestinal growth and tissue formation by promoting regeneration of the epithelial surface of the digestive system.
Elsiglutide is under development by Helsinn as a potential first-ever therapy against chemotherapy-induced diarrhea.
Global development and commercial rights to elsiglutide for its use in cancer supportive care outside the Nordic countries are licensed to Helsinn (www.helsinn.com).
About the Phase IIb dose-ranging trial with elsiglutide
The trial was a randomized, stratified, double-blind, double-dummy, parallel group, placebo-controlled, dose finding, multicenter, multinational, Phase IIb trial in patient with colorectal cancer receiving 5-fluorouracil (5-FU)-based chemotherapy (FOLFOX or FOLFIRI). Patients received, starting from the day of chemotherapy administration, a single daily dose subcutaneously of elsiglutide 10, 20 or 40 mg or placebo for four consecutive days. Each patient was in the study for three consecutive chemotherapy cycles. The treatment period for each patient was four consecutive days of the first two chemotherapy cycles.
Two populations were planned for this study. The population receiving FOLFOX or FOLFIRI without monoclonal antibody was defined as the target population (at least 120 patients per treatment group, for a total of 480 patients), while the population concomitantly receiving monoclonal antibody was defined as the additional population (up to 30 patients per treatment group, total maximum of 120 patients). The primary endpoint was the proportion of patients with diarrhea of grade >2 or more during the first cycle of chemotherapy. The primary analysis took into consideration only the target population.
