Definitions
- the invention relates to liposomally encapsulated taxol. its manufacture and its use. Areas of application of the invention are medicine and the pharmaceutical industry.
- Taxol is a natural substance found in the bark of various yew species (Taxazeen), which is derived from these barks [J. Amer. Chem. Soc, 93: 2325 (1971)] or more recently also by chemical synthesis [J. Amer. Chem. Soc, 1110: 5917-5919 (1988)]. Taxol has a completely new mode of action compared to previously known cytostatics [Ann. NY. Acad. Be. 466: 733-744 (1986); Sartorelli, A. (ed.): Molecular Actions and Targets for Cancer Chemotherapeutic Agents. Academic Press, New York, 1981, pp. 483-507].
- Taxol shows a clear antineoplastic activity against various tumors, e.g. against implanted B16 melanoma, P388 leukemia and against human breast tumors.
- Taxol is severely limited due to its low water solubility.
- Solubilizers such as Cremophor (polyethoxylated castor oil) and alcohol improve the solubility, but lead to the use
- Taxol as an almost water-insoluble substance can be dissolved with high efficiency in the lipid phase of liposomes of a suitable composition, so that the toxicities observed by Cremophor EL in humans, including increased chylomicron formation, should no longer occur.
- the therapeutic effectiveness of free, liposomally encapsulated and nanoparticulate taxol is compared in vitro on two leukaemias, the P388 and the L1210. While the inhibition of growth of the P388 cells was the same for all 3 drug forms, the L1210 was more sensitive to the nanoparticulate form.
- Taxol liposomes produced show improved stability.
- Taxol-liposome combinations are claimed, of which in particular
- Vesicles with a positive charge based on cardiolipin, phosphate idylcholine and cholesterol were produced and examined.
- the aim of the invention is to provide liposomally encapsulated taxol with a high taxol content and higher stability, and thus increased therapeutic effectiveness.
- the task is to develop specific forms of Taxol encapsulation and to use them, possibly in combination with other free or liposomally encapsulated substances, for the treatment of different types of tumors and localizations.
- the focus is also on preventing the dose-limiting neutropenic effect of the unencapsulated taxol, e.g. by combination with liposomal carboplatin.
- the invention also relates to a pharmaceutical preparation which contains the liposomally encapsulated taxol according to the invention and pharmaceutically customary excipients and additives.
- a practically advantageously usable mixture contains 0.98 mg taxol in 50 mg phosphatidylcholine (98% of the amount of taxol used).
- the liposomal encapsulation takes place by high pressure homogenization or by spontaneous vesicle formation.
- a prefabricated liposome mixture in solid or liquid form is combined with taxol, subsequently homogenized several times (preferably twice) at 5-160 MPa and optionally subsequently lyophilized.
- the production process for the production of a taxol-containing liposomal preparation by means of high-pressure homogenization, and possibly the release of liposomes from such a preparation comprises the following steps:
- REPLACEMENT LEAF Liposomes according to Example 1 were used for animal experiments. It could be shown, inter alia, on a human mamma carcinoma (MaTu) that this liposome preparation compared to free taxol (4 days of therapy, 12.5 mg / kg per day) after only one application of 50 mg / kg showed improved therapeutic efficacy with lower haematotoxicity (Fig. 1 + 2).
- the encapsulants used are a) a natural, semi-synthetic or fully synthetic amphiphile, such as a lipid, a surfactant or an emulsifier, b) a charged lipid component and / or a saturated lipid component, an ether lipid component, c) a polymer d) a carrier liquid and optionally additional auxiliaries, such as Contains nano particles.
- the amphiphile preferably has the formula I given in claim 3.
- the charged lipid component used is preferably: the anion of dicethylphosphate, palmitic acid, stearic acid, the anion of a phospholipid, such as phosphatidylserine or phosphatidic acid, or the anion of a sphingolipid such as sulfatide.
- phosphatidylglycerol is used as the charged lipid component.
- the invention can equally be implemented with neutral lipid components such as phosphatidylcholine or saturated lipid components such as dipalmitoylphosphatidylcholine.
- the polymer used is e.g. Polyethylene glycol of molecular weight 2000-10000.
- Physiological saline is generally used as the carrier liquid.
- aqueous medium in volume fractions of 1 to 30% of the volume of the preparation and mechanical mixing e.g. the three-dimensional gel structure is disassembled and the preformed liposomes released by manual shaking or using a vortex mixer.
- the liposome dispersion can be filtered through filters with a pore size of 0.1 ⁇ m to 1 ⁇ m.
- the preparation according to the invention which contains liposomes in a tight package (liposome gel), is suitable as an active substance depot which slowly releases the active substance, either in dissolved form or in the form of individual liposomes containing active substance.
- This preparation can be applied by injection (e.g. i.m., i.p.) or implantation. However, insertion into body cavities or application to mucous membranes, the cornea of the eye (cornea) or areas of the skin is also possible.
- the preparation thus serves as a carrier of the active ingredient and, if necessary, for its modified release.
- the preparation according to the invention which contains liposomes in free-flowing form, is suitable as a carrier of the active ingredient.
- This preparation can be applied by injection (e.g. i.v., i.m.) or also by introducing it into body cavities or by applying it to mucous membranes, the cornea of the eye (comea) or areas of skin.
- the encapsulated liposomes according to the invention lead to a distribution of the liposomal active ingredient in the body, which selectively brings about a high and long-lasting active ingredient concentration at the site of action and thus to an improvement in the action or an improvement in the ratio of action to side effect.
- the taxol / encapsulant / propellant mixture of metered dose aerosols is sprayed and forms after the evaporation of
- preformed taxol liposomes can be nebulized. This route is particularly preferable if direct use against lung metastases is intended.
- the liposomally encapsulated taxol can be used as a cytostatic. This can be used alone or in combination with other active ingredients such as carboplatin or liposomally encapsulated carboplatin. Preference is given to use against him tumors, malignant melanomas, liver metastases, pulmonary metastases, breast carcinomas and against urogenital carcinomas. During treatment i.a. A human breast carcinoma on the nude mouse showed a significant tumor volume inhibition after a single administration of 50 mg kg liposomally encapsulated taxol compared to the treated taxol group (4x12.5 mg / kg).
- a lipid film consisting of 1500 mg of egg phosphatidylcholine and 30 mg of taxol is dispersed in 30 ml of sterile, calcium-free phosphate-buffered (pH 7.2-7.4) sodium chloride solution.
- the resulting dispersion of multilayer liposomes is treated in a high pressure homogenizer (Gaulin Mikrolab 40) at 700 bar.
- the resulting liposome dispersion (SUV) can be stored for a short time at 4 degrees Celsius and is suitable for parenteral (IV) application. Gel formation or lyophilization is suitable for longer storage.
- Liposomes produced as in Example 1 are aerosolized with a suitable nebulizer (e.g. Aero-Tech II) and thus made accessible for inhalation.
- a suitable nebulizer e.g. Aero-Tech II
- 200 mg taxol, 200 mg encapsulant according to claim 2 and 400 ul ethanol (90%) are metered into a pressurized gas container.
- a metering valve e.g. Perfect Valois DF 10/150 ACT
- 10 ml of liquefied dimethyl ether are added to the preparation, so that the clear to opalescent or slightly cloudy solution is formed.
