Also, Arrowhead will discuss findings from an ARC-520 study with a background therapy of nucleotide/nucleoside analog inhibitors (NUCs) tenofovir and/or entecavir.
In its release, Arrowhead listed a few of its key findings as follows:
- Arrowhead’s proprietary DPC platform can effectively and consistently knock down target genes in humans.
- ARC-520 achieves significant HBV s-Antigen (HBsAg) reductions in humans, particularly in treatment naïve, HBeAg-positive patients.
- Arrowhead identifies a large target HBV population for ARC-520 and describes a new paradigm for the HBV lifecycle.
- ARC-520 induces deep HBsAg reduction in chronically HBV infected chimps and one of four HBeAg-positive chimps demonstrated signs of immune reactivation during therapy.
- ARC-520 has been well tolerated.
- Arrowhead expands its HBV portfolio by nominating an additional clinical candidate that is complementary to ARC-520.
Arrowhead Research is a biopharmaceutical company developing targeted RNAi therapeutics. The company is leveraging its proprietary Dynamic Polyconjugate delivery platform to develop targeted drugs based on the RNA interference mechanism that efficiently silences disease-causing genes.

Christopher Anzalone, Ph.D., president and CEO of Arrowhead, said:
These are exciting data that represent a significant leap forward for our DPC platform, ARC-520, and the HBV field. We have achieved the highest knockdown ever reported in humans with RNAi and a safety profile that continues to be excellent. We are optimistic that this will ultimately translate into powerful clinical outcomes for ARC-520 and follow-on candidates against multiple indications.
