Background : ALX-0081 is a bivalent Nanobody ® based on the variable domain of naturally occurring heavy-chain only antibodies. It binds with high affinity to the A1 domain of von Willebrand Factor (vWF) and thereby blocks the interactions between platelets and vascular collagen. It selectively prevents thrombus formation under high shear stress conditions. Aim : Test ALX-0081 single IV infusions (60 minutes) dosed from 0.5mg to 12mg total in 40 male healthy volunteers in double-blind, randomized, placebo controlled study and assess pharmacokinetic (PK), pharmacodynamic (PD), safety and immunogenicity. Results : ALX-0081 displayed non-linear pharmacokinetic properties, following a 2 compartment model. Ristocetin induced platelet aggregation (RIPA) was analyzed as marker for PD effect with full inhibition (defined as measured levels dropping <10%) observed at ALX-0081 concentrations of ~ 400ng/ml. All subjects dosed ≥ 2mg achieved full RIPA inhibition at 1h post-dosing for maximum of 12h. ALX-0081 treatment was well tolerated and safe, no signs of bleeding were reported and no immunogenic response was detected. Target related mild and transient reductions of vWF and FVIII plasma levels were observed and all events were fully reversible. Phase Ib study design : double-blind, randomized, placebo controlled, multiple ascending dose study. ALX-0081 added to standard anti-thrombotic regimen (ASA, clopidogrel, UFH) in patients with stable angina undergoing elective PCI. Single-dose escalation will be followed by multiple dosing (up to 4 doses in 24h). Dose escalation will be guided by safety and efficacy marker. Endpoints: safety, pharmacological profile, biomarker (RIPA, RICO and ACT) and early clinical outcome (MACE, IMR, molecular marker). Conclusion : ALX-0081 can be administered safely over a wide range of dose-regimen. First results of the phase Ib study in stable angina patients will be presented.

Psychotropic Compound

SummaryModafinil is a new psychotropic compound with central α1, adrenergic-stimulant activity in animals. In the present study, its pharmacological activity in man was evaluated in the sleep-deprivation induced psychomotor and cognitive impairment paradigm. This was a double-blind placebo-controlled study involving 12 healthy volunteers. Standard psychomotor and memory tasks were used, including critical flicker fusion frequency determination (CFF), choice reaction time and short- and long-term memory evaluation. Results revealed a clear antagonism by modafinil of the psychomotor and cognitive impairment induced by sleep-deprivation in most tasks 6 h after drug administration, and marginal effects 18 h after. These results therefore support a psychostimulant activity of modafinil in man.

Chloride channels modulate gastrointestinal neuromuscular functions in vitro. Lubiprostone, a selective type 2 chloride channel (ClC-2) activator, induces intestinal secretion and has been shown to relieve constipation in clinical trials; however, the effects of lubiprostone on gastric function and whole gut transit in humans are unclear. Our aim was to compare the effects of the selective ClC-2 activator lubiprostone on maximum tolerated volume (MTV) of a meal, postprandial symptoms, gastric volumes, and gastrointestinal and colonic transit in humans. We performed a randomized, parallel-group, double-blind, placebo-controlled study evaluating the effects of lubiprostone (24 μg bid) in 30 healthy volunteers. Validated methods were used: scintigraphic gastrointestinal and colonic transit, SPECT to measure gastric volumes, and the nutrient drink (“satiation”) test to measure MTV and postprandial symptoms. Lubiprostone accelerated small bowel and colonic transit, increased fasting gastric volume, and retarded gastric emptying. MTV values were reduced compared with placebo; however, the MTV was within the normal range for healthy adults in 13 of 14 participants, and there was no significant change compared with baseline measurements. Lubiprostone had no significant effect on postprandial gastric volume or aggregate symptoms but did decrease fullness 30 min after the fully satiating meal. Thus the ClC-2 activator lubiprostone accelerates small intestinal and colonic transit, which confers potential in the treatment of constipation.
