Helsinn Announces That Phase 2/3 Pivotal Trials for NEPA (netupitant 300 mg +
oral palonosetron 0.50 mg), Will be Published in the Annals of Oncology

LUGANO, Switzerland, July 10, 2014 /PRNewswire/ --
Helsinn Group, the company focused on building quality cancer care, today
announces that the complete results of the three Phase 2/3 pivotal trials for
the investigational oral fixed-dose combination capsule of netupitant 300 mg +
oral palonosetron 0.50 mg (NEPA), which is licensed to Eisai Inc. in the
United States, have been published, together with an accompanying editorial,
in the July issue of Annals of Oncology.
The first study (Hesketh, et al) was a pivotal, Phase 2, randomized,
double-blind, dose-ranging study in 694 patients undergoing cisplatin-based,
highly emetogenic chemotherapy. Three different doses of oral netupitant (100,
200 and 300 mg) in combination with oral palonosetron (0.50 mg) plus
dexamethasone were compared with oral palonosetron (0.50 mg) plus
dexamethasone. All NEPA doses showed significantly higher overall (0-120 hour)
complete response rates (no emesis, no rescue medication), the primary
endpoint, compared with oral palonosetron, with the highest NEPA (300 mg) dose
studied showing an incremental benefit over lower NEPA doses for all efficacy
endpoints. On the basis of these results, this dose combination was selected
for continued development.
The second study (Aapro, et al) was a multinational, randomized, double-blind,
parallel-group Phase 3 study in 1455 chemotherapy-naïve patients receiving
anthracycline-cyclophosphamide moderately emetogenic chemotherapy. Patients
were randomized to receive either oral NEPA plus dexamethasone or oral
palonosetron plus dexamethasone, all administered only on Day 1 prior to
chemotherapy. The percentage of patients who met the primary endpoint of
complete response in the delayed (25-120 hours) phase was significantly higher
in the NEPA group compared with the oral palonosetron group, which was also
seen in the acute (0-24 hours) and overall (0-120 hours) phases post
The third multinational, double-blind, Phase 3 study (Gralla, et al) in 413
patients was designed primarily to demonstrate the safety of NEPA over
multiple cycles of either highly (24% of patients) or moderately emetogenic
chemotherapy (76% of patients). Patients were randomly assigned (at a 3:1
ratio) to receive NEPA plus dexamethasone or aprepitant plus oral palonosetron
and dexamethasone. Patients completed 1961 total chemotherapy cycles with 75%
of patients completing ≥4 cycles. The adverse event profile was consistent
with that expected for patients
undergoing cytotoxic chemotherapy, with the most frequently reported
treatment-related events being headache and constipation.
As a strong advocate for adherence to evidence-based antiemetic guidelines
such as those issued by the American Society of Clinical Oncology (ASCO), the
European Society for Medical Oncology (ESMO) and the Multinational Association
of Supportive Care in Cancer (MASCC), Dr. Aapro suggested that this fixed-dose
NEPA combination provides an opportunity to overcome some of the barriers
interfering with guideline adherence and in doing so offers potential for
improving prevention of CINV for patients. He added that these papers in
Annals of Oncology have raised such interest that the authors were pleased to
be invited to contribute to a "research highlight" summary which is in the
July issue of Nature Reviews Clinical Oncology .
Helsinn ' s Chief Executive Officer, Riccardo Braglia , commented: "We are
delighted to see that Phase II/III pivotal trials for NEPA, licensed to Eisai
in the United States, will be published in the Annals of Oncology . The two
efficacy studies met their primary end points showing that oral NEPA has
significantly higher complete response rates compared with oral palonosetron,
whilst the safety study confirmed the safety profile for NEPA. Overall, the
studies suggest NEPA will be a useful addition for patients to prevent CINV.
This underscores Helsinn's commitment to excellence in cancer supportive
About Netupitant 300 mg + Oral Palonosetron 0.50 mg (NEPA)
NEPA is currently under review by the U.S. Food and Drug Administration (FDA)
and the European Medicines Agency (EMA). NEPA is an investigational
single-day, oral, fixed-dose combination of a selective NK  receptor
antagonist, netupitant, and a 5-HT  receptor antagonist, oral palonosetron,
believed to target two critical signaling pathways associated with
chemotherapy-induced nausea and vomiting (CINV).
