Inhibitex reports third quarter financial results and recent corporate developments

-4.25 log10 IU/mL reduction in HCV RNA levels observed with once-daily administration of 200 mg INX-189-

ATLANTA, Nov 04, 2011 (BUSINESS WIRE) -- ---Conference Call Today at 9:00 a.m. EDT-

Inhibitex, Inc. /quotes/zigman/92379/quotes/nls/inhx INHX +104.29% today announced its financial results for the third quarter ended September 30, 2011 and provided an update on several recent corporate developments, including top-line safety and antiviral data from the first cohort in its ongoing clinical trial designed to evaluate higher doses of INX-189, an oral nucleotide polymerase inhibitor, being developed to treat chronic infections caused by hepatitis C virus (HCV), administered as monotherapy or in combination with ribavirin for seven days.

"We are very pleased with the progress we have made in the clinical development of INX-189 over the past several months, as well as the continued potent, dose-dependent antiviral activity it is demonstrating as monotherapy in genotype 1 treatment-naive HCV patients," stated Russell H. Plumb, President and CEO of Inhibitex, Inc. "We look forward to expanding the scope of our Phase 2 program to include interferon-free combinations of INX-189 with other antiviral agents in HCV genotype 1, 2, and 3 patients in 2012."

Recent Corporate Developments

INX-189 for Chronic Hepatitis C -- The Company today reported top-line safety and antiviral data from the first cohort of its ongoing clinical trial of INX-189, which is primarily designed to further evaluate the safety, tolerability, pharmacokinetics and antiviral activity of higher doses of INX-189, administered as monotherapy, or in combination with ribavirin, for seven days in treatment-naive patients with chronic HCV genotype 1. In this study, 200 mg INX-189, dosed once-daily for seven days, continued to demonstrate potent and dose-dependent antiviral activity with a median HCV RNA reduction from baseline of -4.25 log10 IU/mL. Further, 200 mg INX-189 was generally well tolerated, and there were no serious adverse events (SAE) or dose dependent adverse events (AE) observed.

In September, the Company announced the initiation of this trial, which includes other planned cohorts of 100 mg INX-189 dosed once daily in combination with ribavirin, 100 mg INX-189 dosed twice daily as monotherapy, 100 mg INX-189 dosed with food, and possibly higher monotherapy doses of INX-189. Earlier this year, the Company reported positive top-line safety and antiviral data from its initial multiple ascending dose Phase 1b clinical trial of INX-189, whereby INX-189, when dosed once-daily at 9 mg, 25 mg, 50 mg and 100 mg for seven days, demonstrated dose-dependent antiviral activity with median HCV RNA reductions from baseline of -0.64, -1.00, -1.47, and -2.53 log10 IU/mL, respectively.

The Company also reported today that it has initiated a Phase 1 drug/drug interaction study in healthy volunteers of INX-189 and an HCV direct acting antiviral compound, the objective of which is to evaluate the safety, tolerability and pharmacokinetics of the two compounds in contemplation of the Company expanding its Phase 2 clinical development program to include interferon-free combinations of INX-189 with other antiviral agents in HCV genotype 1, 2, and 3 patients in 2012. The Company anticipates that this study will be completed by year-end.

In September, the Company also announced the commencement of a 90-patient randomized, placebo controlled, response-guided, Phase 2 clinical trial to evaluate the safety, tolerability and antiviral activity of INX-189 in combination with pegylated interferon and ribavirin in chronic HCV-infected genotype 2 and 3 treatment-naive patients. This ongoing clinical trial is designed to evaluate three once-daily doses of INX-189 (25 mg, 50 mg and 100 mg) administered in combination with pegylated interferon and ribavirin for 12 weeks, and includes a control arm in which patients will receive placebo and standard of care treatment (a combination of pegylated interferon and ribavirin for 24 weeks). Each INX-189 combination treatment cohort in the trial is expected to include 25 patients, and the control arm is expected to include 15 patients. Patients in the INX-189 containing treatment arms that achieve an extended rapid viral response, or eRVR, defined as having HCV RNA below the level of detection after 28 days and 12 weeks of dosing, will stop all therapy after 12 weeks. Those patients who do not achieve an eRVR will continue receiving pegylated interferon and ribavirin for 12 additional weeks. Patients will be followed for 24 weeks after end-of-treatment to determine if they achieve a sustained viral response (SVR), which is the currently accepted definition of cure for chronic HCV infections. The Company anticipates completing enrollment in this trial around year end.

The Company is presenting two abstracts at the upcoming annual meeting of the American Association for the Study of Liver Diseases (AASLD) in San Francisco beginning November 4, 2011. On August 2, 2011, AASLD posted the titles of these abstracts on its website, which are:

-- Antiviral Activity and Safety of INX-08189, a Nucleotide Polymerase Inhibitor, Following 7-Days of Oral Therapy in Naive Genotype-1 Chronic HCV Patients

-- Preclinical Characterization of a Series of Highly Potent Phosphorodiamidate Nucleotide Analogue Inhibitors of Hepatitis C Polymerase.

FV-100 -- In August, the Company announced its intentions to file a protocol and other associated submissions, including a patient reported outcomes (PRO) dossier, to the FDA for a proposed Phase 2b trial of FV-100 in order to obtain feedback on the protocol, its PRO methodology, and a regulatory pathway that could potentially support an indication for the reduction of shingles-associated pain and/or the incidence of post-herpetic neuralgia (PHN). The Company anticipates submitting these documents to the FDA this month. Subject to satisfactory regulatory review and feedback concerning the proposed clinical endpoints and the potential to support an indication for the reduction of shingles-associated pain and/or incidence of PHN, the Company will determine whether it will initiate the proposed Phase 2b study of FV-100 in 2012.

Third Quarter 2011 Financial Results

As of September 30, 2011, the Company held $53.7 million in cash, cash equivalents, short-term and long-term investments.

The Company reported a net loss in the third quarter of 2011 of $5.3 million, which was the same net loss it reported in the third quarter of 2010. While the net loss in each of these quarters was essentially the same, the net loss in the third quarter of 2011 resulted from an increase in milestone revenue earned in the quarter that was offset by higher research and development expense. Basic and diluted net loss per share was $0.07 for the third quarter of 2011, as compared to $0.08 for the third quarter of 2010.

Revenue for the third quarter of 2011 increased to $1.3 million from $0.3 million in the third quarter of 2010 due to a $1.0 million milestone earned and received from our licensee and collaborator, Pfizer, Inc. associated with the initiation of a Phase 1/ 2 clinical trial of a 4-antigen Staphylococcus aureus (S. aureus) vaccine (SA4Ag) during the quarter.

Research and development expense increased to $5.7 million in the third quarter of 2011 from $4.7 million in the third quarter of 2010. The $1.0 million increase was primarily due to a $0.4 million increase in direct costs incurred with the initiation of both the Phase 2 genotype 2/3 clinical trial of INX-189 and the additional clinical trial of INX-189 designed to evaluate higher doses of INX-189 administered as monotherapy or in combination with ribavirin for seven days, as well as an increase in non-direct expenses of $0.6 million related to an increase in research and development personnel and higher use of laboratory supplies.

General and administrative expense was $0.9 million in the third quarter of 2011, which was the same amount as reported in the third quarter of 2010.
