• mice previously receiving a dose of 3 mg were administered ibudilast at a dose of 18 mg/Kg during Test Cycle 9.
• ibudilast at a dose of 12 mg/Kg reduced ethanol in alcohol dependent mice.
• ibudilast at a dose of 12 mg/Kg or 18 mg/Kg is effective at reducing ethanol intake in alcohol dependent mice to ethanol intake levels for mice in the control group (FIG. 2).
• Decreased ethanol intake moreover, does not result from a general suppression of ingestive behavior. Ibudilast was observed to reduce ethanol drinking in alcohol dependent mice at doses that did not affect ethanol drinking in mice in the control group.
• decreased ethanol intake was associated with significant increases in concurrent water intake. While Ibudilast, especially at the 9 mg/Kg dose, produced transitory reductions in 24-hour food intake, but not water intake in P and HAD rats this effect diminished over the 5-day test phase.
• ibudilast 50 mg BID
• Human studies were conducted to test that: (1) ibudilast (50 mg BID) does not adversely alter the cardiovascular response to alcohol administered intravenously; (2) ibudilast (50 mg BID) alters the subjective response to alcohol administered intravenously and alcohol-induced cravings; and (3) ibudilast (50 mg BID) alters stress- induced and cue-induced craving.
• TLFB TLFB Back
• the study comprised a treatment group and a placebo group and each participant completed a daily assessment questionnaire to address changes in mood, withdrawal effects, alcohol cravings, and address issues pertaining to other side effects.
• ibudilast 50 mg 5 x 10 mg capsules twice daily (BID) or placebo (PBO).
• BID twice daily
• PBO placebo
• each participant in the test group received 20 mg of ibudilast twice a day (bid) on days 1 and 2 of the study.
• the dose was increased to two separate doses of 50 mg each on days 3-6.
• participants Upon reaching a stable target dose of ibudilast (or placebo), participants completed a stress-exposure paradigm on day 5 (PM), an alcohol cue-exposure on day 6 (AM), and an intravenous alcohol challenge on day 6 (PM). Following the intravenous alcohol challenge, participants were monitored for 24 hours and then discharged. Following a 5-10 day washout period study participants were readmitted to the CTRC where they received the opposite treatment (IBUD or PBO) for the second part of the study. See Figure 3.
• IV-A Intravenous Alcohol Administration
• Infusion was performed by the study nurse under the supervision of the study physician using a 6% alcohol IV infusion.
• An alcohol infusion nomogram provides a formula for obtaining the rate of infusion based on the participant's gender and weight.
• male participants' were infused at a rate determined by the following formula: 0.166- ml/minute X weight in kilogram while the rate of infusion for female participants was calculated as 0.126-ml/minute X weight in kilograms.
• Breath alcohol content was monitored every 3 to 5 minutes during infusion until target BrAC's of .02 g.dl, .04 g.dl, .06 g.dl, and .08 g.dl were obtained, following which infusion rates were reduced to half the original rate to maintain stable BrAC levels during the testing phase.
• the present study also assessed the reactivity of participants to alcohol cues at each dose of medication such that participants served as their own controls. Repeated cue assessments may be useful because studies have indicated that not all alcohol dependent patients are cue reactive. The CR assessments followed well-established procedures and participants received standardized instructions about the assessment as they became acclimated to the psychophysiological monitors.
• CR assessment sessions began with a 3 -minute relaxation period, in which participants were asked to sit quietly and do nothing. Participants then held and smelled a glass of water for 3 minutes as a standard procedure to control for the effects of simple exposure to any potable liquid, followed by a second 3 -minute relaxation period. Next, each participant held and smelled a glass of their preferred alcoholic beverage for three minutes. During each trial, the participant was asked to sniff the beverage for 5 consecutive seconds upon hearing a tone sound. Thirteen tone sounds were administered during each 3- minute block of time. The intervals between tone sounds were varied to ensure that each participant receives the same olfactory exposure.
• each participant rated his/her urge to drink alcohol using the 11 -point Likert scale (e.g., "none at all” to "extremely strong urge”).
• Heart rate beats per minute; BPM
• blood pressure systolic, diastolic, and mean arterial pressure [MAP]
• BPM heart rate
• MAP mean arterial pressure
• Therapeutic efficacy of ibudilast was gauged based on the compound's ability to attenuate or abolish cue-induced cravings for alcohol consumption.
• SR Stress Reactivity Assessment
• Ibudilast was well tolerated and safe during the study. No subjects dropped out of the study for adverse event-related reasons and there were no dose reductions of ibudilast during the course of the study. Out of the 24 potential adverse drug effects, only headache was reported in significantly greater frequency during the ibudilast vs. placebo regimens (p ⁇ 0.05); specifically 4 vs. 0 instances). In the context of alcohol consumption, ibudilast did not affect heart rate or blood pressure either as a main effect or as a moderator of alcohol's effects across the BrACs (p's > 0.35).
• Ibudilast did not affect subjective response to alcohol during the infusion.
• Baseline scores for depressive symptomology were collected.
• Responses to Alcohol Challenge e.g., alcohol-induced stimulation, positive affect, negative affect, "liking,” and “wanting" were compared between subjects with higher BDI scores (more depressive symptomology) and dysphoria and subjects with lower BDI scores (less depressive symptomology) and dysphoria.
