REP 2139 (Гепа Б)

[Water]

HBsAg and HDV RNA reduction with REP 2139-Ca and peg-INF alpha 2a in chronic HBV/HDV infection.

Nucleic acid polymers (NAPs) inhibit the release of HBsAg and the NAP REP 2139 can efficiently clear HBsAg from the blood of patients with HBV mono-infection. REP 2139-Ca therapy combined with pegylated interferon alpha-2a is being evaluated in Caucasian patients with HBV/HDV co-infection (NCT02233075).

Patients received REP 2139-Ca once weekly for 15 weeks (500 mg) by 2 h IV infusion, followed by combined therapy for 15 weeks with pegylated interferon alpha-2a (180ug SC qW) with 250 mg REP 2139-Ca. Patients then transition to 33 weeks of pegylated interferon alpha-2a monotherapy. HDV RNA, HBV DNA, HBsAg and anti-HBs are followed every two weeks using standard assays (Robogene RT- PCR, Abbott RealTime HBV, Abbott Architect).
On treatment, observed HBsAg reductions are currently *5 logs in 6 patients (all \1 IU / ml), *3 logs in three patients and *0.5 to 1.5 logs in three patients. HDV RNA is currently undetectable in ten patients (*5 to 8 log reduction from baseline) with *3 and *5 log reductions observed in the other two patients. Substantial elevation (389–15,408 mIU/ml) of serum anti-HBs and the development of liver flares were only observed with the onset of exposure to pegy- lated interferon alpha-2a and was only evident in patients with serum HBsAg \1 IU / ml at the start of immunotherapy.
REP 2139-Ca is able to achieve rapid reductions in serum HBsAg and HDV RNA in Caucasian patients with HBV/HDV infection. REP 2139-Ca may become an important new therapeutic option for patients with chronic HBV/HDV infection.

За 15 недель (+33 недели на пегах только) существенно уменьшил колво HBV и HBsAg, тем самым является потенциальным средством лечения как Гепатита Б, так и Гепатита Д.

Replicor Inc., a privately held biopharmaceutical company targeting a cure for patients with chronic hepatitis B virus (HBV) and chronic HBV and hepatitis delta virus (HDV) co-infection, will present preclinical and updated clinical data on REP 2139-Ca based combination therapies in HBV infection and HBV / HDV co-infection at the 25th Annual Meeting of the Asia Pacific Association for the Study of the Liver to be held from February 20 -24, 2016 in Toyko, Japan. Three presentations on Replicor technology will be made during the meeting:

HBV RNA is emerging as a potential new marker of viremia in patients with HBV infection. In patients with HBeAg positive HBV infection, treatment with REP 2139-Ca and immunotherapy (in the REP 102 protcol), not only leads to reduction / clearance of HBsAg and HBV DNA and the appearance of anti-HBs but also to reduction of HBV RNA as well. The characterization of the HBV RNA response in the REP 102 protocol was done in collaboration with the lab of Dr. Hendrik Reesink at the Amsterdam Medical Center, and will be presented by Dr. Reesink in the Presidential Plenary Session on February 22nd.

An update on the clinical response data from HBV /HDV co-infected patients completing REP 2139-Ca / peg-interferon combination therapy and transitioning to peg-interferon monotherapy in the REP 301 protocol will be presented in an oral presentation on Feb 22nd (O-130).

A poster presentation on the effects of combined treatment with REP 2139-Ca and tenofovir disoproxil fumarate and entecavir on serum and liver virema in vivo will be presented on Feb 22nd (P-0329).

These pre-clinical and clinical studies continue to advance Replicor’s understanding of the antiviral effects of REP 2139-Ca based combination therapies and how these can be used to benefit patients with HBV infection or HBV / HDV co-infection.
