Abstract
The invention relates to a sustained release pharmaceutical formulation adapted for administration by injection containing the compound fulvestrant, 7alpha-[9-(4,4,5,5,5-pentafluoropentylsulphiny1)nony1]oestra-1,3,5(10)-triene-3,17beta-diol, at concentration of at least 100mg/ml in solution in a ricinoleate vehicle which additionally comprises at least one alcohol and a non-aqueous ester solvent which is miscible in the ricinoleate vehicle.
Description
The present invention relates to be applicable to sustained release pharmaceutical formulation by drug administration by injection, described pharmaceutical preparation inclusion compound fulvestrant, promptly 7 α-[9-(4; 4; 5,5,5-five fluorine amyl group sulfinyls) nonyl] female-1; 3; 5 (10)-triolefins-3,17-isoallopregnane-3 is as the solution in the ricinoleate carrier; the concentration of chemical compound fulvestrant is at least 100mg/ml, and comprises at least a pure and mild a kind of non-aqueous ester solvent that can be miscible with described ricinoleate carrier in addition.
The blocking-up estrogen action is very important to treating many optimum and virulent mastopathy and genital diseases.Premenopausal women achieves the above object surgical operation, radiotherapy or the measure of internal medicine medicine of ovary defunctionalization by execution, and the postmenopausal women then uses aromatase inhibitor.
The alternative medicine of blocking-up estrogen action is with estrogen antagonist medicine antagonism estrogen action.These medicines combine and competition with estrogen receptor (ER) in being present in estrogen response histiocyte nuclear.Conventional on-steroidal estrogen antagonist medicine (as tamoxifen) effective competition ER combination, but its curative effect usually is subject to the part agonism that they presented, and cause to block fully estrogen-mediated activity (Furr and Jordan, Pharmacology ﹠amp; Therapeutics, 25:127-206,1984; May and Westley, J Biol Chem 262:15894-15899,1987).
Because on-steroidal estrogen antagonist medicine may have agonist properties, impel thus and seek novel chemical compound, this compounds should combine with ER with high-affinity, but does not activate replying of any normal transcription hormone, thereby does not have estrogen action.This quasi-molecule will be " pure " estrogen antagonist medicine, with the similar part of tamoxifen tangible difference be arranged, and can eliminate estrogenic Nutrition fully.This compounds is referred to as estrogen receptor downward modulation regulator (E.R.D).Design and the ultimate principle of testing novel pure antiestrogen medicine are seen Bowler etc. 1989, Wakeling1990a, 1990b, 1990c; Wakeling and Bowler 1987,1988.
At 7 α bit strips the estradiol steroid analog of alkyl sulfenyl base side chain being arranged is the examples of compounds (Bowler etc. 1989) that the first kind does not have estrogen activity.Chemical compound 7 α-[9-(4 to have selected one of them; 4; 5; 5; 5-five fluorine amyl group sulfinyls) nonyl] female-1,3,5-(10)-triolefin-3; 17-isoallopregnane-3 has carried out intensive research, and its reason is that this chemical compound has pure estrogen antagonist activity and its estrogen antagonist usefulness obviously is better than other existing estrogen antagonist medicine.About 7 α-[9-(4,4,5; 5,5-five fluorine amyl group sulfinyls) nonyl] female-1,3; 5 (10)-triolefins-3, the results of in vitro studies of 17-isoallopregnane-3 and early stage clinical experience impel this medicinal do treatment estrogen of exploitation to rely on disease (as breast carcinoma and some optimum gynaecopathia) medicine.
7 α-[9-(4,4,5,5,5-five fluorine amyl group sulfinyls) nonyl] is female-1,3,5 (10)-triolefins-3, and the international generic name of 17-isoallopregnane-3 or ICI 182,780 is a fulvestrant, uses this title hereinafter.When mentioning fulvestrant, should comprise its pharmaceutically acceptable salt and its any possible solvate.
Fulvestrant is similar to estradiol in conjunction with the affinity of ER, and at the external growth stimulation of blocking estradiol to the human breast cancer cell fully; In this respect, it is stronger and more effective than tamoxifen.Fulvestrant is blocked estradiol fully at rat, mice, the intravital uterotrophic effect of monkey, also blocks the uterus nutritional activities of tamoxifen.
Because fulvestrant does not have clinical effective estrogen antagonist medicine such as tamoxifen or the distinctive estrogen-like stimulation activity of toremifene fully, so its therapeutic activity strengthens, it is faster, more complete or the persistent period is longer that characteristic shows as tumor regression; Incidence rate reduction of treatment resistance and tumor are soaked the power of attacking and are reduced.
In perfecting the adult rat body, give fulvestrant can not damage the dosage that rings bone density or can not cause gonadotrophin secretion to increase, degenerated in the uterus.If also like this in human body, then these results of study are of crucial importance clinically.Bone density reduces to have limited endometriosis is continued to adopt the time of blocking the estrogen action therapy.Fulvestrant is not blocked hypothalamic ER.The blocking-up estrogen action also causes or aggravates hot flush and other menopausal symptoms; Fulvestrant will can not produce these effects, because it can not pass through blood brain barrier.
European Patent Application No. 0138504 disclosed some steroid derivatives is effective estrogen antagonist medicine.The disclosure comprises the data that relates to the steroid derivatives preparation.Especially it is female-1,3 to disclose chemical compound 7 α-[9-(4,4,5,5,5-five fluorine amyl group sulfinyls) nonyl] in embodiment 35,5 (10)-triolefins-3, and 17-isoallopregnane-3 has specifically been enumerated this chemical compound in claim 4.The chemical compound that it also discloses that invention can provide use with pharmaceutical composition (steroid derivatives and the pharmaceutically acceptable diluent or carrier that comprise this invention) form.Point out that wherein described compositions can be the form that is fit to oral or parenterai administration.
The same with other steroid type chemical compound, some physical property of fulvestrant makes them be difficult to preparation.Even compare with other steroid, fulvestrant also is lipophilic especially molecule, and its water solublity is extremely low, approximately 10ngml-1 (being the solute estimator in water/solvent mixture, because can not the so low solute amount of measurement in the water only arranged).
At present, many business-like steroid release injectable preparations are arranged.General these preparations use oil to make solvent, and wherein may add excipient.
At US 5,183, among 814 embodiment 3, the oily injection preparation of fulvestrant has been described, described preparation contains the Oleum Ricini (making the volume of making solution is 1ml) of fulvestrant 50mg, benzyl alcohol 400mg and q.s.At US 5,183, the described preparation of the industrial-scale production described in 814 relates to use high concentration alcohol.Therefore, need to reduce the determining alcohol in the fulvestrant preparation, will prevent fulvestrant from preparation, to precipitate simultaneously and separate out.
Following table has been listed the dissolubility of fulvestrant in various different solvents.
The dissolubility of fulvestrant
| Solvent | Dissolubility (mg/ml, 25 ℃) |
| Water | ????0.001 |

Used term " pharmaceutical preparation " is meant that medicine adds the combination of preparations carrier in this.Term " final preparation " is all identical with " pharmaceutical preparation " implication with " final pharmaceutical preparation ".
Used term " preparations carrier " is meant the combination (and therefore not comprising medicine itself) of all excipient that are used for described pharmaceutical preparation in this.
Because following reason must be paid attention to the difference between pharmaceutical preparation and preparations carrier.For example, if the concentration of excipient " A " (y% weight/volume) is the concentration that records in preparations carrier, after adding, medicine will cause the concentration of excipient A in final pharmaceutical preparation to be lower than concentration y so.Concentration with " preparations carrier " expression to be converted to the concentration in " final pharmaceutical preparation ", must use displacement value.
" displacement value " is defined as replacing the weight portion of the chemical compound of a weight portion preparations carrier.Displacement value can be used for determining the amount of the metathetical preparations carrier of combined thing.Displacement value is used to calculate the definite composition in the final preparation of excipient ratios.The amount of the required preparations carrier of density influence preparation correct concentration pharmaceutical preparation of chemical compound.One weight portion density equals the chemical compound of preparations carrier will replace isopyknic preparations carrier.The carrier that the replaceable halfbody of chemical compound of twice preparations carrier density is long-pending.Therefore must use displacement value that chemical compound is revised with regard to concrete preparations carrier.
When each component of preparation is used term % weight/volume (percentage by weight of every volume of formulation), for fear of any doubt, we are meant the component that has constant weight percentage ratio in the unit volume preparation, and for example 1% weight/volume preparation is meant and comprises the 1g component in the 100ml preparation.Further following illustrating also.
| X% weight/volume preparation | The weight of x in the 1ml preparation |
| ????30％ ????20％ ????10％ ????5％ ????1％ | ????300mg ????200mg ????100mg ????50mg ????10mg |
When using integer representation % weight/volume preparation, they are meant the number through suitably rounding up.For example 4.6% will be rounding to 5%.
Should understand in when preparation, may comprise excessive dosage and make doctor on duty or nursing staff give required dosage.Therefore, when needs 5ml dosage, have in preparation that the excessive of the highest 0.25ml is suitable, preferably have the excessive of the highest 0.15ml.In general preparation will leave in phial or the prefilled syringe, be preferably to contain the unit dose prefilled syringe of described preparation in this, and these have constituted other features of the present invention.
Described pharmaceutically acceptable alcohol can comprise a kind of alcohol or two or more pure mixture, is preferably the mixture of two kinds of alcohol.The pharmaceutically acceptable alcohol that is preferred for parenteral is the mixture of ethanol, benzyl alcohol or ethanol and benzyl alcohol.
Described pharmaceutically-acceptable non-aqueous ester solvent can comprise the mixture of a kind of pharmaceutically-acceptable non-aqueous ester solvent or two or more these kind solvents, preferably only is a kind of ester.The non-aqueous ester solvent of the preferred pharmaceutical compositions of parenteral is selected from benzyl benzoate, ethyl oleate, isopropyl myristate, isopropyl palmitate or their any mixture.
Those skilled in the art understand the requirement (such as the requirement of American Pharmacopeia, British Pharmacopoeia, European Pharmacopoeia and Japanese Pharmacopoeia) that described pharmaceutically acceptable alcohol satisfies standards of pharmacopoeia qualitatively and may comprise some water and other organic solvents, and for example ethanol is that content is the ethanol of 94.9-96.0% (volume) when measuring for 15.56 ℃ in the American Pharmacopeia.Dehydrated alcohol in the American Pharmacopeia is that 15.56 ℃ of following ethanol contents are not less than the ethanol of 99.5% (volume).
Those skilled in the art understand the requirement (such as the requirement of American Pharmacopeia, British Pharmacopoeia, European Pharmacopoeia and Japanese Pharmacopoeia) that described pharmaceutically-acceptable non-aqueous ester solvent satisfies standards of pharmacopoeia qualitatively.
The combination of the pure and mild pharmaceutically-acceptable non-aqueous ester solvent of preferred pharmaceutical compositions is described below in preparation:
Used term ricinoleate excipient is meant the oil of the ratio of glyceryl triricinoleate in its composition for (at least 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% or 95% weight/volume).Described ricinoleate carrier can be an artificial oil, and also being fit to is Oleum Ricini, and all meets standards of pharmacopoeia as mentioned above.
We find that uncannily above-mentioned preparation of the present invention provides the release of secular gratifying fulvestrant after intramuscular injection.
Though we find that at other solubilization excipient of preparation injection back be that pure and mild pharmaceutically-acceptable non-aqueous ester solvent disappears fast from preparations carrier and injection site, preparation of the present invention still can discharge the fulvestrant of treatment produce effects level in long-time.
Used term " slow release " is meant the continuous release of at least 4 weeks of acquisition, at least 5 weeks and preferred at least 8 all fulvestrants in this.Under a preferable feature, can obtain at least 8 all i.e. slow release of 2 months, more preferably obtain the slow release at least 12 weeks or 3 months.
Should understand doctor on duty and may wish with divided dose intramuscular injection administration, promptly the 5ml preparation is divided into two independent 2.5ml order administrations, and this is another feature of the present invention.
Simply fulvestrant is added to be dissolved in and to expect to obtain good release profiles in the oil-based fluid preparation.
The dosage of preferred intramuscular injection administration is 5ml.
Conventional other excipient that uses of described formulation art be can use, for example anti-oxidation and antisepsis agent, coloring agent or surfactant comprised.The preferred optional excipient is a surfactant, more preferably antioxidant.
As mentioned above, fulvestrant can be used for treating estrogen dependent conditions for example breast carcinoma and gynaecopathia (as endometriosis).
Except that fulvestrant, the molecule of another similar type is at present just in clinical research.Infer SH-646 (11 β-fluoro-7 α-(14,14,15,15,15-five fluoro-6-methyl isophthalic acid 0-sulfo--6-azepine pentadecyls) female-1,3,5 (10)-triolefins-3,17-isoallopregnane-3) also be the chemical compound that has with fulvestrant same function mode, and it have very similarly chemical constitution.Think that this chemical compound also has similar physical property to fulvestrant, so the present invention also applies for this chemical compound protection together.
Except substituting the fulvestrant with SH-646, other features of this invention as mentioned above.

(a) with 3 months the body giving drugs into nose being carried out in these 7 kinds of pharmaceutical preparatioies studies for kinetics (PK); The result is shown in Fig. 1,2 and 3.
The pharmacokinetic interpretation of result
Pro-blood plasma level comparison variation in the same old way in 30 days is big; After this change to similar in the same old way.After 2 months, levels of drugs equals 1 month level in the same old way, shows that comparison action time is long in the same old way.This release profiles is amazing because with localized precipitation medicine not to compare in the same old way, think that originally the localized precipitation that is subjected to the test preparation injection site can destroy its release profiles.
Pro-notices in 30 days that curve has some differences, therefore they is divided into two groups (preparation F7 has shown intermediate characteristic).
The A group, early stage rapid release (50% benzyl benzoate and low Oleum Ricini≤15%)-referring to Fig. 2 A
The B group, low release, more flat curve (≤30% benzyl benzoate and higher Oleum Ricini 〉=20%)-referring to Fig. 2 B
