Intec Pharma Reports Top-Line Phase 3 Trial Results of Accordion Pill-Carbidopa/Levodopa in Advanced Parkinson's Disease PatientsJERUSALEM, July 22, 2019 -- (Healthcare Sales & Marketing Network) -- Intec Pharma Ltd. (NASDAQ: NTEC) ("Intec" or "the Company") today announces top-line data from the Company's pivotal Phase 3 trial (the ACCORDANCE trial) evaluating the safety and efficacy of the Accordion Pill®-carbidopa/Levodopa (AP-CD/LD) compared with immediate release CD/LD (IR-CD/LD; Sinemet®) as a treatment for the symptoms of advanced Parkinson's disease (PD). The company announced that the ACCORDANCE study did not achieve statistical superiority to Sinemet on the primary endpoint of reduction in daily OFF time.
Levodopa is the most widely used and most effective drug for the symptomatic therapy of PD. However, chronic levodopa therapy is problematic due to the development of motor complications, which can be disabling, difficult to treat, and may limit the usefulness of the drug. OFF periods and dyskinesia are some of the most prevalent motor complications for advanced PD patients and they have a significant impact on quality-of-life and healthcare costs.
Key Findings of the ACCORDANCE Trial
- AP-CD/LD provided treatment for Parkinson's disease symptoms but did not demonstrate a statistically significant reduction in OFF time over that obtained with IR-CD/LD under the conditions established in the protocol.
- Treatment-emergent adverse effects (TEAEs) observed with AP-CD/LD were generally consistent with the known safety profile of CD/LD formulations and no new safety issues were observed throughout the double-blinded study, during the gastroscopy safety sub-study or the 12-month open-label extension (OLE) study.
"We sincerely thank the patients, families and clinical trial sites involved in this study for their commitment to advancing research in Parkinson's disease. We hope the body of clinical data we have gathered can ultimately be used to benefit PD patients," stated R. Michael Gendreau, Chief Medical Officer of Intec Pharma. "Upon our on-going preliminary review of the data, we have noted that certain subsets of patients performed particularly well. In those patients, we see a meaningful reduction in OFF time. We will continue to analyze the full data set and expect that such findings will help inform our strategy for AP-CD/LD moving forward."
The ACCORDANCE Phase 3 Clinical Trial
The Phase 3 ACCORDANCE study is a multi-center, global, randomized, double-blind, double-dummy, active-controlled, parallel-group study in adult subjects with advanced PD. The study was conducted at over 90 clinical sites throughout the U.S., Europe and Israel. Prior to the 13-week randomized and double-blinded 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 then optimized on the active comparator, Sinemet, and then on AP-CD/LD. The study enrolled 462 patients in the Sinemet titration period to provide for the 320 patients that were randomized into the 13-week, double-blinded portion of the study.
All patients completing the 13-week randomized period were eligible to continue in an open-label extension study in which they receive treatment with AP-CD/LD for an additional 12 months. More than 90% of eligible patients elected to enter the OLE study.
Primary and Secondary Endpoints
The primary efficacy endpoint of the study was the change from baseline to endpoint in the percent of daily OFF time during waking hours based on Hauser home diaries. The study was 90% powered to detect a one-hour difference in OFF time between Sinemet and AP-CD/LD. Under the protocol and conditions of the ACCORDANCE study, AP CD/LD did not demonstrate statistical superiority to Sinemet on daily OFF time.
Secondary endpoints 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 Parts 2 and 3. AP-CD/LD also did not achieve statistical superiority on these endpoints.
Safety and Tolerability
Treatment-emergent adverse effects observed with AP-CD/LD were generally consistent with the known safety profile of CD/LD formulations. No new safety issues were observed throughout the double-blinded study, during the gastroscopy safety sub-study or the 12-month open-label extension (OLE) study.

About the Accordion Pill Technology
The Accordion Pill is a drug delivery system that uses biodegradable polymeric films, which combine and load drugs and actives ingredients onto these films, folds them into an undulated shape and then places them inside a capsule. This innovative drug delivery system has a number of unique advantages based on its gastric retentive properties. With the Accordion Pill, drug is released slowly in the stomach over hours, allowing the body to absorb it more steadily. When the pill is done, it simply dissolves in the GI tract.
The Accordion Pill carbidopa/Levodopa (AP-CD/LD) is a gastric-retentive drug delivery system containing carbidopa and levodopa in both immediate and extended-release modes. The innovative gastric retentive qualities of AP-CD/LD provide extended-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.
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 Europe. There are estimated to be more than 600,000 Parkinson's disease patients in the U.S. who experience motor fluctuations, a condition where with disease progression patients experience both "wearing off" (where they have trouble with movement), and "dyskinesias" or uncontrolled movements. More than 400,000 of these patients in the U.S. experience in excess of one hour per day of motor fluctuations.
The majority of Parkinson's disease patients are treated with LD. However, LD treatment is often 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.
