Clinical Data
On April 7, 2014, Idenix Pharmaceuticals, Inc. (the Company or Idenix) issued a press release announcing continued
progress of the Companys program to develop nucleotide prodrug inhibitors for the treatment of hepatitis C virus (HCV) infection. Specifically, Idenix announced:
IDX21437: Topline 7-Day Phase I/II Clinical Results
In
January 2014, Idenix initiated the seven-day proof-of-concept portion of a phase I/II clinical trial for IDX21437. The trial completed enrollment of 44 treatment-naïve, genotype (GT) 1, 2 or 3 HCV-infected patients. Patients were randomized to
receive once-daily doses of placebo, 50 mg, 150 mg, or 300 mg of IDX21437 for seven days. The topline clinical results include:
|
|
|
IDX21437 was well-tolerated with no observed pattern of adverse events or laboratory abnormalities. |
|
|
|
Treatment with IDX21437 exhibited potent pan-genotypic activity in a dose-dependent manner: |
|
|
|
In GT 1 HCV-infected patients (n=8), the mean maximal viral load reduction was 4.2 log10 IU/mL in the 300 mg arm. |
|
|
|
The mean maximal viral load reduction of 4.3 log10 IU/mL was achieved in GT 2 and 3 HCV-infected patients in the 300 mg arm (n=10). |
|
|
|
Based on these findings, the 300 mg dose of IDX21437 has been chosen for the anticipated phase II combination study with samatasvir. |
IDX21459: Phase I Clinical Program
In April 2014, Idenix
initiated enrollment for the healthy volunteer portion of a phase I clinical trial of IDX21459 in Europe. This portion of the study is expected to enroll approximately 50 healthy volunteers and will evaluate once-daily doses of IDX21459 ranging from
10 mg 300 mg. The proof-of-concept portion of the study is expected to enroll a total of 40 treatment-naïve, genotype 1 HCV-infected patients who will receive once-daily doses of placebo, 50 - 300 mg of IDX21459 for seven days. IDX21459
has shown a favorable preclinical profile including potent, pan-genotypic activity and favorable safety with respect to cardiac, mitochondrial and genotoxicity assessments.
Additional Nucleotide Candidates
Idenix also announced
that the Company has elected not to continue its clinical development program for HCV nucleotide prodrug, IDX20963, previously placed on clinical hold by the U.S. Food and Drug Administration.
The full text of the press release is attached hereto as Exhibit 99.1. Exhibit 99.1 is
incorporated by reference into this Current Report on Form 8-K.
