The diarylquinoline TMC207 for multidrug-resistant tuberculosis.

Background: The diarylquinoline TMC207 offers a new mechanism of antituberculosis action by inhibiting mycobacterial ATP synthase. TMC207 potently inhibits drug-sensitive and drug-resistant Mycobacterium tuberculosis in vitro and shows bactericidal activity in patients who have drug-susceptible pulmonary tuberculosis.

Methods: In the first stage of a two-stage, phase 2, randomized, controlled trial, we randomly assigned 47 patients who had newly diagnosed multidrug-resistant pulmonary tuberculosis to receive either TMC207 (400 mg daily for 2 weeks, followed by 200 mg three times a week for 6 weeks) (23 patients) or placebo (24 patients) in combination with a standard five-drug, second-line antituberculosis regimen.

Early bactericidal activity and pharmacokinetics of the diarylquinoline TMC207 in treatment of pulmonary tuberculosis.

Tibotec Medicinal Compound 207 (TMC207) is a novel diarylquinoline with a unique mode of action that targets mycobacterial ATP synthase. TMC207 exhibits high in vitro activity against mycobacterial strains either susceptible or resistant to all first-line and many second-line drugs, including fluoroquinolones, and has shown exceptional in vivo activity against several mycobacterial species in different animal models. In this early bactericidal activity study, 75 treatment-naïve patients with smear-positive pulmonary tuberculosis were randomized to once-daily oral TMC207 (25 mg, 100 mg, or 400 mg), 600 mg rifampin (RIF), or 300 mg isoniazid (INH) for 7 days.

Pharmacokinetics of itraconazole and hydroxyitraconazole in healthy subjects after single and multiple doses of a novel formulation.

Originally, itraconazole for parenteral administration was licensed in a 40% hydroxypropyl-beta-cyclodextrin (HPBCD) solution for intravenous administration. A novel formulation, the NanoCrystal formulation (NCF), was prepared. NCF consists of drug particles of approximately 200 to 300 nm.

A randomized, double-blind, placebo-controlled study of itraconazole capsules for the prevention of deep fungal infections in immunodeficient patients with HIV infection.

Objectives: To determine whether systemic or deep fungal infections can be prevented, a double-blind, placebo-controlled, phase III trial of itraconazole prophylaxis was undertaken in HIV-infected patients.

Methods: HIV-1 infected patients with CD4 counts < 300 cells/microL were treated with itraconazole (200 mg per day) or matching placebo and followed for 2 years. Development of deep fungal infections, episodes of mucocutaneous candidiasis, change in CD4 count, survival and safety data were collected at each study visit.

Intravenous and oral itraconazole versus intravenous amphotericin B deoxycholate as empirical antifungal therapy for persistent fever in neutropenic patients with cancer who are receiving broad-spectrum antibacterial therapy. A randomized, controlled trial.

Background: Amphotericin B deoxycholate is currently the standard empirical antifungal therapy in neutropenic patients with cancer who have persistent fever that does not respond to antibiotic therapy. However, this treatment often causes infusion-related and metabolic toxicities, which may be dose limiting.

Objective: To compare the efficacy and safety of itraconazole with those of amphotericin B as empirical antifungal therapy.

Intravenous itraconazole followed by oral itraconazole in the treatment of invasive pulmonary aspergillosis in patients with hematologic malignancies, chronic granulomatous disease, or AIDS.

The pharmacokinetics, efficacy, and safety of intravenous (iv) itraconazole (2 days at 400 mg/day, 12 days at 200 mg/day), followed by 12 weeks of oral capsules (400 mg/day) were studied in 31 immunocompromised patients with pulmonary invasive aspergillosis. All patients received iv itraconazole (median duration, 14 days), and 26 then received oral itraconazole (median duration, 78.5 days).

Itraconazole oral solution and intravenous formulations: a review of pharmacokinetics and pharmacodynamics.

Itraconazole is a triazole antifungal agent with a broad spectrum of activity. It is well tolerated and highly efficacious, particularly because its main metabolite, hydroxy-itraconazole, also has considerable antifungal activity. Two new formulations of itraconazole, an oral solution and an intravenous formulation, have recently been developed, which combine lipophilic itraconazole with cyclodextrin.

Itraconazole versus amphotericin B plus nystatin in the prophylaxis of fungal infections in neutropenic cancer patients.

The efficacy and safety of itraconazole oral solution and a combination of amphotericin B capsules plus nystatin oral suspension were compared in the prophylaxis of fungal infections in neutropenic patients. In an open, randomized, multicentre trial, 144 patients received itraconazole oral solution 100 mg bd, and 133 patients received amphotericin B 500 mg tds plus nystatin 2 MU qds. Overall, 65% of itraconazole-treated patients were considered to have had successful prophylaxis, compared with 53% in the polyene group.

Pharmacology of itraconazole.

Itraconazole is a triazole antifungal agent that has a broad spectrum of activity and is well tolerated. Itraconazole is highly efficacious, particularly because its main metabolite, hydroxy-itraconazole, also has considerable antifungal activity. The original capsule formulation of itraconazole may lead to variability in absorption and the plasma concentration.

Pharmacokinetics and safety of a 7-day administration of intravenous itraconazole followed by a 14-day administration of itraconazole oral solution in patients with hematologic malignancy.

The pharmacokinetics and safety of an intravenous hydroxypropyl-beta-cyclodextrin solution of itraconazole administered for 7 days followed by itraconazole oral solution administered at 200 mg once or twice daily for 14 days were assessed in 17 patients with hematologic malignancies. Steady-state plasma itraconazole concentrations were reached by 48 h after the start of intravenous treatment. The mean trough plasma itraconazole concentration at the end of the intravenous treatment was 0.

Itraconazole oral solution for primary prophylaxis of fungal infections in patients with hematological malignancy and profound neutropenia: a randomized, double-blind, double-placebo, multicenter trial comparing itraconazole and amphotericin B.

Systemic and superficial fungal infections are a major problem among immunocompromised patients with hematological malignancy. A double-blind, double-placebo, randomized, multicenter trial was performed to compare the efficacy and safety of itraconazole oral solution (2.5 mg/kg of body weight twice a day) with amphotericin B capsules (500 mg orally four times a day) for prophylaxis of systemic and superficial fungal infection.

A double-blind comparison of itraconazole oral solution and fluconazole capsules for the treatment of oropharyngeal candidiasis in patients with AIDS.

This double-blind trial compared the clinical and mycological efficacy and safety of itraconazole oral solution with those of fluconazole capsules in the treatment of oropharyngeal candidiasis in patients with AIDS. A total of 244 patients were enrolled and randomized to one of three groups for treatment with itraconazole oral solution (100 mg twice daily for 7 days or 100 mg once daily for 14 days) or fluconazole capsules (100 mg once daily for 14 days). Among 194 evaluable cases, complete response (clearance of all symptoms and signs) or marked improvement was noted in 54 of 60 patients (90%) receiving once-daily itraconazole and in 65 of 72 fluconazole-treated patients (90%) at the end of treatment; these results were statistically equivalent (P = .

Repeated-dose pharmacokinetics of an oral solution of itraconazole in infants and children.

The safety, tolerability, and pharmacokinetics of an oral solution of itraconazole and its active metabolite hydroxyitraconazole were investigated in an open multicenter study of 26 infants and children aged 6 months to 12 years with documented mucosal fungal infections or at risk for the development of invasive fungal disease. The most frequent underlying illness was acute lymphoblastic leukemia, except in the patients aged 6 months to 2 years, of whom six were liver transplant recipients. The patients were treated with itraconazole at a dosage of 5 mg/kg of body weight once daily for 2 weeks.

Concentrations in plasma and safety of 7 days of intravenous itraconazole followed by 2 weeks of oral itraconazole solution in patients in intensive care units.

Pharmacokinetics and safety of a hydroxy-beta-propyl solution of itraconazole were assessed in 16 patients in an intensive care unit. On the first 2 days, four 1-h infusions of 200 mg were given at 0, 8, 24, and 32 h. From day 3 to 7, inclusive, a single 1-h infusion of 200 mg of itraconazole was given daily.

Effect of food on the pharmacokinetics of a new hydroxypropyl-beta-cyclodextrin formulation of itraconazole.

Study Objective: To compare the pharmacokinetics of a single 100-mg oral dose of itraconazole administered as 10 ml of a 10-mg/ml itraconazole solution in hydroxypropyl-beta-cyclodextrin under fasting versus postprandial conditions.

Design: Open-label, two-way, randomized, crossover study.

Setting: Janssen Research Foundation, Belgium.

Itraconazole: pharmacology, clinical experience and future development.

Itraconazole is an orally active, broad-spectrum, triazole antifungal agent which has a higher affinity for fungal cytochrome P-450 than ketoconazole but a low affinity for mammalian cytochrome P-450. Itraconazole has a broader spectrum of activity than other azole antifungals and shows interesting pharmacokinetic features in terms of its tissue distribution. These properties have resulted in reduced treatment times for a number of diseases such as vaginal candidiasis, as well as effective oral treatment of several deep mycoses, including aspergillosis and candidiasis.

Oral candidosis: treatment with absorbable and non-absorbable antifungal agents in children.

Oral candidosis in neonates and children is a common infection which occurs often during the first few months after birth, but occasionally also in older children with certain predisposing factors. In neonates, oral candidosis is usually benign, although the symptoms of such an acute infection can be disturbing to both the patient and the parents. In older children developing oral candidosis, specific predisposing factors may be present (e.

Phase II trial: an evaluation of oral saperconazole in acute vaginal candidosis: a comparison of three dosage schedules.

In an open, randomized phase II comparative study, 256 patients with acute vaginal candidosis (less than two episodes of vaginal candidosis in the 6 months preceding study entry) were treated with saperconazole according to one of the following treatment schedules: 2 x 100 mg o.d. for 1 day (87 patients), 2 x 100 mg b.

Oral treatment with itraconazole of aspergilloma in cavitary lung cancer.

We report a case of aspergilloma in a necrotic small cell lung cancer, where poor pulmonary function and performance status of the patient precluded surgical treatment. High dose Itraconazole, a new oral anti-mycotic drug, was given for 13 months. During this treatment there was a decrease of the fungus ball size and no haemoptysis.

A double-blind vehicle-controlled study of R 68 151 in psoriasis: a topical 5-lipoxygenase inhibitor.

Recently the pharmacologic role of leukotrienes (LTs), especially that of LTB4, has been intensively investigated in psoriasis. In vitro, R 68 151 is a potent 5-lipoxygenase inhibitor and consequently reduces LTB4 formation. Therefore the role of an in vitro 5-lipoxygenase inhibitor and its clinical use in psoriasis were evaluated with topical R 68 151 in a double-blind vehicle-controlled study.

Use of topical ketanserin in the treatment of skin ulcers: a double-blind study.

The use of a 2% ointment formulation of ketanserin, an S2-serotoninergic blocking agent, was investigated in a randomized double-blind clinical trial for its effect on the healing of wounds of patients with decubitus, venous, and ischemic skin ulcers. The result demonstrates a significant difference in favor of the ketanserin-treated group (35 patients) versus the placebo-treated group (37 patients) on the basis of two factors: formation of granulation tissue and epithelialization. In addition, a significant difference of 150% in the initial velocity of wound closure was observed in favor of the patients treated with ketanserin.

Itraconazole versus ketoconazole for the prophylaxis of fungal infection in neutropenic children: results of two consecutive nonrandomized studies.

Two consecutive nonrandomized studies were conducted in children with prolonged granulocytopenia to evaluate the prophylactic antifungal activity of ketoconazole and the new triazole itraconazole. The conditions were equivalent in both studies. The incidence of colonization was 10% in the ketoconazole group and 19% in the itraconazole group (this difference is not significant).

Antifungal prophylaxis with itraconazole in prolonged neutropenia: correlation with plasma levels.

Seventy-two patients with haematological malignancies were treated prophylactically with itraconazole during remission induction therapy. The incidence of proven fungal infections was 18%, of which 12.5% were fatal.

Ketoconazole 2% cream versus hydrocortisone 1% cream in the treatment of seborrheic dermatitis. A double-blind comparative study.
