23 Days ago


  •  PDC-1421 high-dose data meets primary endpoint on MADRS scale in ITT clinical trial population
  • PDC-1421 low-dose and PDC-1421 high-dose each proved safe, were well-tolerated, and had no serious adverse events associated with them in Phase II clinical trial
  • Company is planning for end-of-Phase II meetings with regulatory authorities to discuss path forward for Phase III pivotal trials

                      

FREMONT, CA, Nov. 14, 2019 (GLOBE NEWSWIRE) -- via NEWMEDIAWIRE -- American BriVision (Holding) Corporation (OTCQB: ABVC) (the “Company”), a clinical-stage biopharmaceutical company developing therapeutic solutions in oncology/hematology, CNS, and ophthalmology, today issued a full clinical study report (CSR), under the U.S. Food and Drug Administration (FDA) and Taiwan FDA (TFDA) clinical protocol code of BLI-1005-002, for ABV-1504 major depressive disorder (MDD) Phase II study. 

This study consisted of:

  • Part I - an open label, dose escalation study conducted in 12 adult patients for 4 weeks across multiple centers with PDC-1421 low-dose (380 mg) and PDC-1421 high-dose (2 x 380 mg), three times per day
  • Part II - a double-blinded and placebo-controlled trial conducted in parallel groups across 60 adult patients for 6 weeks in multiple centers and randomized (1:1:1) between PDC-1421 low-dose (380 mg), PDC-1421 high-dose (2 x 380 mg), and placebo, three times per day

The study was conducted by Stanford University and five major medical centers in Taiwan. PDC-1421 is the active pharmaceutical ingredient of ABV-1504. 

The clinical study report (CSR) provided the following key study results:

  1. PDC-1421 high-dose (2 x 380 mg) met the prespecified primary objective by demonstrating a highly significant 13.2-point reduction in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score in Intention-To-Treat (ITT) population, averaged over the 6-week treatment period from baseline (i.e., overall treatment effect), as compared to a 9.2-point reduction in the placebo group. In the per protocol population, the high-dose cohort had a 13.4-point reduction in MADRS as compared to an 8.6-point reduction in the placebo group. 
  2. In the ITT population, a greater reduction in net change in HAM-D-17 (Hamilton Depression Rating Scale-17) at week 6 was observed in the high-dose group (-10.95) compared to placebo group (-8.70). A significant group difference in net change in HAM-D-17 and HAM-A (Hamilton Anxiety Rating Scale) at week 2 was also found. Post-hoc, pair-wise comparisons demonstrated a significant difference between high-dose group and placebo group in HAM-D-17 (High dose -7.90 vs. Placebo -4.30; adjusted p = 0.039) and HAM-A (High dose -5.38 vs. placebo -2.90; adjusted p = 0.022), suggesting that subjects who took two PDC-1421 capsules three times per day showed greater improvement compared to those in the placebo group by week 2 (net change = 3.6 for HAM-D-17 and 2.48 for HAM-A). 
  3. Percentage of “responders” in MADRS at week 6 was highest in the high-dose group (High-dose vs. Placebo = 52% [n=11] vs. 35% [n=7] in ITT population; 53% [n=8] vs. 29% [n=4] in the per protocol population).
  4. For the safety endpoint, both the low and high doses of PDC-1421 were safe and well tolerated with no serious adverse events. 

“We believe that the Phase II results of our lead drug candidate PDC-1421 for MDD enable us to initiate End-of-Phase II meetings (EOP2) with the FDA and TFDA regulatory authorities to discuss Phase III and NDA-related plans and an eventual road map for market launch,” said Dr. Howard Doong, Chief Executive Officer of the Company.

As of March 2018 the World Health Organization has reported that more than 300 million people worldwide and of all ages suffer from MDD, also known as clinical depression. Figures from 2017 suggest that MDD affects over 17 million adults, or approximately 7% of the population over age 18, in the U.S., and it is the leading cause of disability in the U.S. for ages 15-44.
