For adjunctive or simultaneous therapeutic administration according to the invention, the NK3 antagonist such as talnetant or its pharmaceutically acceptable salts or solvates and the other active ingredient or their pharmaceutically acceptable salts, derivatives or solvates may each be administered in pure form, but each of the components may be formulated into any suitable pharmaceutically acceptable and effective composition which provides effective levels of the respective component in the body. The choice of the most appropriate pharmaceutical compositions for each component is within the skill of the art, and may be the same form or different forms for each of the components. Suitable formulations include, but are not limited to tablets, capsules, powders, granules, lozenges, suppositories, reconstitutable powders, or liquid preparations such as oral or sterile parenteral solutions or suspensions.
For simultaneous administration as a combined composition of an NK3 antagonist such as talnetant and the other active ingredient or agents according to the invention, the NK3 antagonist such as talnetant or its pharmaceutically acceptable salts or solvates and the other active ingredient and their pharmaceutically acceptable salts, derivatives or solvates may be administered together in pure form, but the combined components may be formulated into any suitable pharmaceutically acceptable and effective composition which provides effective levels of each of the components in the body. The choice of the most appropriate pharmaceutical compositions for the combined components is within the skill of the art. Suitable formulations include, but are not limited to tablets, sub-lingual tablets, buccal compositions, capsules, powders, granules, lozenges, suppositories, reconstitutable powders, or liquid preparations such as oral or sterile parenteral solutions or suspensions.
In one embodiment, in order to obtain consistency of adjunctive administration or simultaneous administration, the compositions of each of the components, or of the combination of the components is in the form of a unit dose.
Unit dose presentation forms of the components, or of the combination of the components, for oral administration may be tablets and capsules and may contain conventional excipients such as binding agents, for example syrup, acacia, gelatin, sorbitol, tragacanth, or polyvinylpyrrolidone; fillers, for example lactose, sugar, maize- starch, calcium phosphate, sorbitol or glycine; tabletting lubricants, for example magnesium stearate; disintegrants, for example starch, polyvinylpyrrolidone, sodium starch glycollate or microcrystalline cellulose; or pharmaceutically acceptable wetting agents such as sodium lauryl sulphate.
The solid oral compositions may be prepared by conventional methods of blending, filling, tabletting or the like. Repeated blending operations may be used to distribute the active agent throughout those compositions employing large quantities of fillers. Such operations are of course conventional in the art. The tablets may be coated according to methods well known in normal pharmaceutical practice, in particular with an enteric coating.
Oral liquid preparations for the components, or for the combination of the components, may be in the form of, for example, emulsions, syrups, suspensions or elixirs, or may be presented as a dry product for reconstitution with water or other suitable vehicle before use. Such liquid preparations may contain conventional additives such as suspending agents, for example sorbitol, syrup, methyl cellulose, gelatin, hydroxyethylcellulose, carboxymethylcellulose, aluminium stearate gel, or hydrogenated edible fats; emulsifying agents, for example lecithin, sorbitan monooleate, or acacia; non-aqueous vehicles (which may include edible oils), for example almond oil, fractionated coconut oil, oily esters such as esters of glycerine, propylene glycol, or ethyl alcohol; preservatives, for example methyl or propyl p-hydroxybenzoate or sorbic acid; and if desired conventional flavouring or colouring agents.
For parenteral administration (for example intravenous, intravascular or subcutaneous administration) of the components, or of the combination of the components, fluid unit dosage forms are prepared utilizing the component or the combination of the components and a sterile vehicle, and, depending on the concentration used, can be either suspended or dissolved in the vehicle. In preparing solutions the components or the combination of the components can be dissolved in water for injection and filter sterilized before filling into a suitable vial or ampoule and sealing. Advantageously, adjuvants such as a local anaesthetic, a preservative and buffering agents can be dissolved in the vehicle. To enhance the stability, the composition can be frozen after filling into the vial and the water removed under vacuum. Parenteral suspensions are prepared in substantially the same manner, except that the component is suspended in the vehicle instead of being dissolved, and sterilization cannot be accomplished by filtration. The components, or the combination of the components can be sterilized by exposure to ethylene oxide before suspending in the sterile vehicle. Advantageously, a surfactant or wetting agent is included in the composition to facilitate uniform distribution of the component or the combination of the components.
The components or the combination of the components may also be formulated as depot preparations. Such long acting formulations may be administered by implantation (for example subcutaneously or intramuscularly) or by intramuscular injection. Thus, for example, the components or the combination of the components of the invention may be formulated with suitable polymeric or hydrophobic materials (for example as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt.
The compositions of each of the components or of the combination or of the components may contain from 0.1% to 99% by weight, such as from 10-60% by weight, of the active material, depending on the method of administration.
In one embodiment, for adjunctive or simultaneous administration, the unit dose of the talnetant component is in the range of 10-600 milligrammes, each unit dose being administered up to four times daily. In one embodiment, the unit dose of the talnetant component is in the range 100-600 milligrammes, each unit dose being administered up to four times daily. The daily and unit doses of the active ingredient will depend upon which active ingredient is employed, but will typically be the recommended or approved dosage for the specific active ingredient when administered as monotherapy. In one embodiment, adjunctive administration of talnetant may permit lower doses of the active ingredient than those normally recommended when the active ingredient is prescribed as monotherapy. Typical daily doses of the active ingredients suitable for use in adjunctive or simultaneous administration according to the invention are shown in Table 1.
Example
The following 3 arm patient study may be performed to evaluate the efficacy and safety of talnetant as adjunctive schizophrenia therapy: talnetant (600mg BID) plus risperidone (2mg BID) will be compared to risperidone (2mg BID) plus placebo and placebo plus placebo in subjects with an acute exacerbation of schizophrenia. This will be an international multicenter, double-blind, randomized study.
Male and female subjects, aged more than 18 years and having an acute exacerbation of schizophrenia (minimum PANSS score of 70) who fulfil the screening criteria will enter a 1-7 day Screening Phase. At the end of the Screening Phase, baseline evaluations will be conducted to determine eligibility for randomization into the Treatment Phase of the study. Eligible subjects will be randomized (1 :1 :1 ) to treatment with risperidone plus talnetant, risperidone plus placebo or placebo plus placebo for a 6-week, double-blind treatment period. All subjects will also return for follow-up assessments 2-weeks after stopping study medication.
The Screening Phase begins with the Screen Visit and can last from 1 to 7 days. At the Baseline visit, evaluations will be conducted to determine eligibility for randomization into the Treatment Phase of the study for all subjects. Subjects who have a PANSS score that has not changed by more than 20% since the initial Screen Visit remain eligible for study participation. Subjects not meeting these criteria are withdrawn from the study. The Treatment Phase will begin the day after the Baseline Visit. Eligible subjects will be randomized (1:1:1) to treatment with risperidone (2mg BID) plus talnetant (600mg BID), risperidone (2mg BID) plus placebo or placebo plus placebo for a 6-week, double-blind treatment period. No dose adjustments will be permitted with risperidone. Subjects with significant tolerability issues will be dropped from the study. No other antipsychotic medications will be permitted during the screening or treatment phase of the study, although certain rescue medications will be specified and permitted.
Subjects will remain in-patient for the duration of the treatment period. The primary efficacy measure, the PANSS total, will be administered at Screen, Baseline, and weekly through the 6-week treatment period. Secondary efficacy measures will be assessed at specific visits.
