The purpose of this study is to evaluate the safety and tolerability (including incidence of central nervous system [CNS] related events such as lightheadedness and dizziness), of multiple oral doses of AL-794 in healthy volunteers (HV). Also, to evaluate the pharmacokinetics of ALS-033719 and ALS-033927 in plasma after multiple oral doses of AL-794 in HV.

Review

Author: Hurt, Aeron C ; Hayden, Frederick G ; Mifsud, Edin J

Current influenza antivirals have limitations with regard to their effectiveness and the potential emergence of resistance. Encouragingly, several new compounds which inhibit the polymerase of influenza viruses have recently been shown to have enhanced pre-clinical and clinical effectiveness compared to the neuraminidase inhibitors, the mainstay of influenza antiviral therapy over the last two decades. In this review we focus on four compounds which inhibit polymerase function, baloxavir marboxil, favipiravir, pimodivir and AL-794 and discuss their clinical and virological effectiveness, their propensity to select for resistance and their potential for future combination therapy with the most commonly used neuraminidase inhibitor, oseltamivir.

BackgroundAL-794 is an orally active prodrug of ALS-033719, which selectively inhibits the endonuclease domain of influenza virus A and B polymerase.MethodsIn a phase 1, double-blinded, randomized, placebo-controlled study, healthy subjects were inoculated intranasally with influenza virus (A/Perth/16/2009 H3N2) after confirmation of infection or on day 4. Subjects received 50 mg of AL-794, 150 mg of AL-794, or placebo twice daily for 5 days. Viral load, influenza symptoms, pharmacokinetics, and safety were evaluated.ResultsA total of 61 subjects were inoculated. In 42 infected subjects, the mean peak viral load for 50-mg AL-794 recipients, 150-mg AL-794 recipients, and placebo recipients was 3.54, 2.77, and 3.72 log10 50% tissue culture infectious doses (TCID50)/mL, respectively. The mean influenza viral load area under the curve in the corresponding treatment groups was 137, 87.5, and 142 log10 TCID50/mL·h, respectively, and the median time to virus nondetection was 117, 75.3, and 108 hours, respectively. AL-794 was well tolerated, and no viral resistance to ALS-033719 was identified.ConclusionFollowing oral administration of AL-794, significant dose-dependent antiviral activity was noted, with a greater decrease in viral load, symptoms, and mucus weight at the 150-mg dose, compared with the 50-mg dose, and no safety concerns for either dose or placebo.Clinical Trials RegistrationNCT02588521.

Background This double-blind, first-in-human Phase I study evaluated pharmacokinetics, safety and tolerability of AL-794 (prodrug of ALS-033719), a potent endonucle-ase inhibitor of influenza A and B in healthy volunteers. Methods Healthy adult volunteers were randomized to AL-794 (50–2,000 mg single ascending doses, fasting) or placebo (5 cohorts, n=6:2 AL-794: placebo/cohort) in part 1, and AL-794 (50–600 mg multiple ascending doses, twice-daily, fed or fasted) or placebo (3 cohorts, n=8:2 AL-794: placebo/cohort) for 7 days in part 2. In part 3, 8 healthy volunteers from part 1 received 450 mg AL-794 ( n=6) or placebo ( n=2) following a high-fat meal. All dosing was done with an oral suspension. Blood and urine samples for pharmacokinetics were collected at scheduled times and analysed for ALS-033719 and ALS-033927 (inactive glucuronide) plasma concentrations using LC-MS/MS. Results ALS-033719 plasma concentrations increased dose proportionately up to 150 mg but less than proportionately above 150 mg. Steady-state was generally achieved by the third dose. ALS-033719 exposure increased following administration with a standard meal (19%–33%) or high-fat meal (3–3.6-fold). ALS-033927 was the major metabolite observed. Renal elimination was negligible (0.2%). Seventeen AL-794-treated healthy volunteers reported ≥1 treatment-emergent adverse event (TEAE; part 1: n=6, 24%; part 2: n=11, 69%). The most common TEAEs were headache (part 1: n=3; part 2: n=5) and dizziness (part 1: n=2; part 2: n=6). Conclusions AL-794 up to 200 mg twice daily achieved ALS-033719 exposures which are expected to be efficacious and were generally tolerated. Further studies are planned to characterize safety and antiviral activity.
