Cognitive Impairment and Diminished Neural Responses Constitute a Biomarker Signature of Negative Symptoms in Psychosis.

The treatment of negative symptoms (NS) in psychosis represents an urgent unmet medical need given the significant functional impairment it contributes to psychosis syndromes. The lack of progress in treating NS is impacted by the lack of known pathophysiology or associated quantitative biomarkers, which could provide tools for research. This current analysis investigated potential associations between NS and an extensive battery of behavioral and brain-based biomarkers in 932 psychosis probands from the B-SNIP database.

Binding of the D3-preferring antipsychotic candidate F17464 to dopamine D3 and D2 receptors: a PET study in healthy subjects with [C]-(+)-PHNO.

Rationale: F17464, a dopamine D3 receptor antagonist with relatively high D3 selectivity (70 fold vs D2 in vitro), exhibits an antipsychotic profile in preclinical studies, and therapeutic efficacy was demonstrated in a randomized placebo-controlled clinical trial in patients with schizophrenia (Bitter et al. Neuropsychopharmacology 44(11):1917-1924, 2019).

Objective: This open-label study in healthy male subjects aimed at characterizing F17464 binding to D3/D2 receptors and the time course of receptor occupancy using positron emission tomography (PET) imaging with a D3-preferring tracer, [C]-(+)-PHNO.

Randomized, double-blind, placebo-controlled study of F17464, a preferential D antagonist, in the treatment of acute exacerbation of schizophrenia.

F17464, a highly potent preferential D3 antagonist, is a novel compound in development for schizophrenia treatment. This phase II, double-blind, randomized, placebo-controlled, parallel-group study in five European countries evaluated the efficacy and safety of F17464, 20 mg twice daily, versus placebo over 6 weeks in patients with acute exacerbation of schizophrenia. Change from baseline to Day 43 of the Positive and Negative Syndrome Scale (PANSS) total score was the primary outcome.

Efficacy and safety of a new 5% minoxidil formulation in male androgenetic alopecia: A randomized, placebo-controlled, double-blind, noninferiority study.

Background: Androgenetic alopecia (AGA) is the most common cause of hair loss in men. Topical minoxidil solutions can help to treat AGA but have to be applied continuously to be effective.

Objectives: A new minoxidil formulation with improved cosmetic characteristics (DC0120, Pierre-Fabre Dermatologie) was tested for noninferiority vs a comparator minoxidil product (ALOSTIL , Johnson & Johnson) in stimulating hair growth in men with AGA.

Randomized trial of the efficacy and safety of a new oral spray for drug-induced xerostomia.

The aim of this study was to evaluate the efficacy, safety, and tolerability of three formulations of DC161 oral spray, a saliva substitute, and a comparator in relieving drug-induced xerostomia. This was an open-label, randomized, 4-period, cross-over study in adult subjects with drug-induced xerostomia and documented hyposalivation. During each of the four 1-day periods, one product (one of three DC161 formulations or the comparator) was applied at T0 and then at T4h (before a meal).

Adjunctive levetiracetam in children, adolescents, and adults with primary generalized seizures: open-label, noncomparative, multicenter, long-term follow-up study.

Purpose: To evaluate the long-term efficacy and tolerability of adjunctive levetiracetam (LEV) in patients with uncontrolled idiopathic generalized epilepsy (IGE).

Methods: This phase III, open-label, long-term, follow-up study (N167; NCT00150748) enrolled patients (4 to <65 years) with primary generalized seizures (tonic-clonic, myoclonic, absence). Patients received adjunctive LEV at individualized doses (1,000-4,000 mg/day; 20-80 mg/kg/day for children/adolescents weighing <50 kg).

Efficacy and safety of levetiracetam as adjunctive therapy in adult patients with uncontrolled partial epilepsy: the Asia SKATE II Study.

This study evaluated the safety and efficacy of levetiracetam as adjunctive therapy for partial seizures in everyday clinical practice in Asian populations. Patients aged > or =16 years (N=251) with inadequately controlled partial epilepsy were recruited from 29 centers across Asia. Levetiracetam was added to existing antiepileptic medication for 16 weeks at a starting dose of 500 or 1000 mg/day and titrated to a maximum of 3000 mg/day according to clinical response.

Clinical pharmacology of levetiracetam for the treatment of epilepsy.

Levetiracetam is an antiepileptic drug that is mainly indicated for the adjunctive treatment of partial-onset seizures in adults and children and of myoclonic and primary generalized tonic-clonic seizures in patients with idiopathic generalized epilepsy. In Europe, levetiracetam is also indicated as monotherapy for partial-onset seizures in patients with newly diagnosed epilepsy. Synaptic vesicle protein 2A is the primary molecular target for its anticonvulsive effect but additional mechanisms may also contribute.

Efficacy and safety of levetiracetam as adjunctive treatment of refractory partial seizures in a multicentre open-label single-arm trial in Korean patients.

This prospective, open-label study evaluated the efficacy and safety of adjunctive levetiracetam (LEV) in Korean adults with uncontrolled partial epilepsy. Study patients had to have an average of at least 1 and not more than 14 partial seizures per month (averaged over a 3-month historical baseline) despite the use of one or two AEDs. Patients initially received LEV 1000 mg/day (administered bid) and could increase to 2000 mg/day after 2 weeks, and to 3000 mg/day after another 2 weeks, to obtain adequate seizure control.
