Replicor is a clinical-stage company developing novel NUCLEIC ACID-BASED POLYMERS (NAPs): oligonucleotides whose antiviral activity is strictly dependent on the polymer chemistry of oligonucleotides which can be preserved independently of the sequence of nucleotides present. NAPs have a very important safety advantage over all other existing oligonucleotide-based drugs such as aptamers, antisense oligonucleotides and siRNA: because NAP’s activity is not sequence dependent, NAPs can be engineered with sequences which retain antiviral activity but which do not have pro-inflammatory activity or off target effects common with other oligonucleotide-based drugs, rendering them safe and well tolerated.
Replicor has focused its efforts on developing a cure for HBV and HDV. Three POC Phase II clinical trials have demonstrated that NAP therapy (including REP 2139-Ca with immunotherapy (Pegasys® or Zadaxin®)) is well tolerated and results in antiviral responses that include:
Additional clinical trial data for CHB is expected in 2016. Replicor’s latest presentation of clinical data can be viewed here.
