JERUSALEM, June 25, 2019 /PRNewswire/ --- Intec Pharma Ltd. (NASDAQ: NTEC) ("Intec" or "the Company") today announces that results from an earlier Phase 2 clinical study of the Accordion Pill®-Carbidopa/Levodopa (AP-CD/LD) in Parkinson's disease (PD) patients were published in the peer-reviewed journal, Parkinsonism and Related Disorders. The article titled, "Pharmacokinetics and efficacy of a novel formulation of carbidopa-levodopa (Accordion Pill®) in Parkinson's disease" is now available online as an e-publication ahead of print. The article can be accessed here.
The article reviews pharmacokinetic and efficacy data from the Company's phase 2, multicenter, open-label, two-way randomized crossover study that evaluated multiple dose strengths of the AP-CD/LD (50/250 mg, 50/375 mg or 50/500 mg) twice daily in one treatment period and an active comparator in the other treatment period. The article presents results from cohorts 1-4 out of the 6 cohorts of PD patients who participated in the study. Pharmacokinetics (PK) and efficacy were evaluated for AP-CD/LD compared with immediate release Carbidopa/Levodopa (IR-CD/LD). Treatment-emergent adverse events (TEAEs) and patient- and investigator-reported measures were also evaluated.
The PK results showed that compared with IR-CD/LD, treatment with either AP-CD/LD dose demonstrated more stable LD plasma concentrations in both fluctuating and non-fluctuating PD patients, and significantly decreased the LD Cmax (57.1% and 66.8% decreases among fluctuating and non-fluctuating patients, respectively).
According to the study's authors, "Overall, the PK profile of AP-CD/LD 50/375 is similar to the PK of intestinal CD/LD infusion and better than PK parameters reported for other orally administered LD products developed for extended dopaminergic effect." 
Treatment with either AP-CD/LD 50/375 dosed twice per day (Cohort 3) or AP-CD/LD 50/500 dosed twice per day (Cohort 4) significantly improved motor fluctuations compared with participants' current treatment. Cohort 3 significantly reduced mean daily OFF time by 44% (p< 0.001) and Cohort 4 significantly reduced mean daily OFF time by 45% (p< 0.001) compared with IR-CD/LD. In Cohorts 3 and 4, total ON time (ON state without dyskinesia), good ON time (ON state or ON with non-troublesome dyskinesia), the proportion of total ON time during waking hours, and the proportion of good ON time during waking hours significantly increased with both AP-CD/LD 50/375 and AP-CD/LD 50/500, while both bad times (OFF state and/or ON with troublesome dyskinesia) significantly decreased with both AP doses compared with IR-CD/LD.
The results also showed that treatment with either AP-CD/LD 50/375 (Cohort 3) or AP-CD/LD 50/500 (Cohort 4) significantly improved both patient and investigator ratings on the Global Clinical Impression compared with current treatment (p< 0.01).
TEAEs 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 study.
"In addition to more consistent LD plasma concentrations with AP-CD/LD regardless of whether patients were experiencing motor fluctuations, this new delivery platform resulted in decreased OFF time compared with the IR form. Given the high correlation of clinical effect with LD pharmacokinetics, the efficacy of the AP-CD/LD 50/500 dose in Cohort 4 was not unexpected," concluded study author, Peter A. LeWitt, M.D., Departments of Neurology, Henry Ford Hospital and Wayne State University School of Medicine in Bloomington, Michigan. "Importantly, the substantially improved ON time for the AP versus IR was attained without an emergence of troublesome dyskinesia."
"The valuable information gathered in this pilot study has informed and guided the further development of the AP for PD in an ongoing phase 3 multicenter, randomized, placebo-controlled study. In the phase 3 study, both 2x and 3x per day regimens of AP-50/400 and AP-50/500 mg doses are being tested. As these doses are the same or similar to those used in the pilot study reported here, similar stable LD and CD plasma levels within the therapeutic range necessary for PD symptom control are expected from the phase 3 study," added Dr. LeWitt, who is also the Principal Investigator of the global Phase 3 ACCORDANCE clinical study evaluating the AP in PD patients.
