Intec Pharma Completes Enrollment of Pivotal Phase 3 Clinical Trial of Accordion Pill™ Carbidopa/Levodopa for the Treatment of Advanced Parkinson's Disease Patients
"We are delighted to achieve this important milestone as it leads us one step closer to potentially bringing a new and much-needed baseline levodopa treatment to advanced PD patients," stated
"We continue to be pleased with the Phase 3 development program for AP-CD/LD as an improved baseline therapy for advanced PD patients. We remain encouraged that more than 90% of eligible patients are electing to enroll in the open label extension (OLE) study as these data will provide the long-term safety required for our regulatory submission. In addition, we initiated a pharmacokinetic (PK) study of three times per day (TID) dosing with AP-CD/LD 50/500 mg and look forward to obtaining these data, as this was a common dosing regimen in the ACCORDANCE study. We believe understanding this PK profile in advanced PD patients will be important for commercial launch. Plans with our commercial manufacturing partner,
About the Phase 3 ACCORDANCE Clinical Trial
The Phase 3 ACCORDANCE clinical trial of AP-CD/LD is a multi-center, global, randomized, double-blind, double-dummy, active-controlled, parallel-group study in adult subjects with advanced PD. Preliminary analysis of the baseline data for the enrolled population shows:
- Average age at study entry was 63 and 65% of enrolled patients were male;
- Entering patients had a diagnosis of PD for 8.8 years on average;
- More than 40% of entering patients required in excess of 800 mg daily of a levodopa (LD) preparation;
- Average daily OFF time for patients upon entering the study was approximately 6.1 hours; and
- Approximately 32% of patients were enrolled in the U.S.
Prior to the 13-week randomized portion of the study, the ACCORDANCE study had two open label periods of 6 weeks each during which all patients in these open label periods were first stabilized and optimized on the active comparator, Sinemet, and then on AP-CD/LD.
The primary efficacy endpoint of the study is the change from baseline to endpoint in the percent of daily OFF time during waking hours based on Hauser home diaries. The study is 90% powered to be statistically significant for a one-hour difference in OFF time between Sinemet and AP-CD/LD.
Secondary endpoints currently include change from baseline to endpoint in "ON time" without troublesome dyskinesia during waking hours, CGI-I at endpoint as recorded by physician and patient and change from baseline through endpoint in the Unified Parkinson's Disease Rating Scale (UPDRS) Score domains.
All patients completing the 13-week randomized period are eligible to continue in an OLE study in which they will receive treatment with AP-CD/LD for an additional 12 months. To date, more than 90% of eligible patients have elected to enter the OLE study.
The Accordion Pill Carbidopa/Levodopa (AP-CD/LD) is a gastric-retentive drug delivery system containing carbidopa and levodopa in both immediate and controlled-release modes. The innovative gastric retentive qualities of AP-CD/LD provides controlled release levodopa to be discharged slowly in the stomach over 8–12 hours, allowing the active ingredients to be absorbed more steadily in the upper GI tract, where levodopa is absorbed. This results in a more stable and predictable PK profile.
Results from a Phase 2 clinical study of AP-CD/LD 50/500 mg dosed twice daily showed a
statistically significant reduction of 45% in OFF time (n=18) and a statistically significant reduction of 42% in ON time with troublesome dyskinesia time (n=18). Together, the proportion of good ON time during waking hours was increased from approximately 61% to approximately 77%.
About Parkinson's Disease
Parkinson's disease is the second most common neurodegenerative disorder in the elderly and it is estimated to affect more than two million people in the U.S. and
The majority of Parkinson's disease patients are treated with LD. However, LD treatment is associated with motor complications, mainly wearing "OFF" periods and LD-induced dyskinesia.
The efficacy and adverse effects of LD are directly related to plasma levels of the drug. Current formulations of LD provide only limited efficacy as LD has a very short half-life of approximately 90 minutes and its absorption is confined to the upper part of the gastrointestinal tract (narrow absorption window). Consequently, stabilizing LD plasma levels remains a major factor for improving anti-parkinsonian control in advanced Parkinson's disease patients.
