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.

what about starting a petition online to get this drug approved in europe?
medhelp is too small but maybe avaz or similar websites might help.i dotn think we can get it approved this way but we spread the word among hbvers about this drug

That's great idea ! Maybe some collecting money online for research ? There is over 200m of people chronically infected so if everyone give 1$...
Thanks for the abstracts :)
I wonder how much time we need to define those patients who achieved seroconversion as "functionally cured" ? 6m, 12m after finishing peginf ?

I am waiting for their presentation-slides...they are much more informative...probably in few days on their website.
There should be another abstract dealing with HbeAg positive HBV patients only. I believe this will be an oral Plenary presentation, hopefully questions can be asked and answered.
