Description

WO 96/11007 PCT/US95/12952 1 PARENTERAL PHARMACEUTICAL COMPOSITIONS CONTAINING GF120918A FIELD OF THE INVENTION The present Invention relates to novel pharmaceutical compositions that are useful in preventing malignant cells from becoming resistant to a diverse variety of chemotherapeutic agents.
BACKGROUND OF THE INVENTION The multidrug-resistance inhibitor, chemically known as tetrahydro-6,7-dimethoxy-2-isoquinolinyl)-ethyl]-phenyl}-9,10-dihydro-5-methoxy- 9-oxo-4-acridine carboxamide and its physiologically acceptable salts and solvates is described and claimed in World Patent Application WO 92/12132, filed in the name of Laboratires Glaxo S.A. and published July 23, 1992. Multidrug-resistance is a process whereby tumor cells become resistant to structurally diverse chemotherapeutic agents following exposure to treatment with anti-tumor drugs.
This acquired drug resistance can be a major obstacle in the clinical treatment and management of malignant disease. It has been shown that this type of resistance can be reversed by GF120918, resensitizing multidrug-resistant tumor cells to various chemotherapeutic agents. It has also been seen that certain tumors are intrinsically multidrug-resistant and the use of multidrug-resistance inhibitors are also beneficial in treating tumors of this type.
GF120918A, the hydrochloride salt of N-{4-[2-1,2,3,4-tetrahydro-6,7dimethoxy-2-isoquinolinyl)-ethyl]-phenyl}-9,10-dihydro-5-methoxy-9-oxo-4acridine carboxamide, to be safely and effectively administered to patients parenterally by either intravenous injection or intravenous infusion must be adequately miscible in the blood. Therefore, any combination of the drug and the various excipients, in a liquid form, must be sufficiently compatible with the physiological composition of the blood to allow sufficient admixing. This mixing with the blood allows the compound to be distributed throughout the body in an unremarkable fashion. However, problems exist with the parental administration of GF120918A due to the compounds poor solubility. GF120918A is a weak base and therefore exhibits a higher solubility at a pH less than about 4. Since the pH of the blood is approximately 7.4, the compound alone in solution precipitates upon injection or infusion into the blood stream.
An object of the present Invention is to provide a parenteral formulation that when injected or infused into the blood stream remains miscible and allows WO 96/11007 PCT/US95/12952 2 the active drug to be distributed throughout the body in an unremarkable fashion.
A further object of the present Invention is to provide a parenteral formulation and method of use that will improve or increase the efficacy of a chemotherapeutic agent or restore sensitivity of a tumor to chemotherapeutic agent or reverse or reduce resistance of a tumor to a chemotherapeutic agent; subsequently abating tumor cell multidrug-resistance and decreasing morbidity.

issued May 27, 1980 and October 20, 1981 both to Ladage et al., teach how to increase the solubility of a compound in a formulation. These publications advocate the use of: cosolvents, complexing agents, hydrotropic agents, liposomes, fat emulsions, polyaphrons, dimethylsulfoxide and surfactants. However, even though GF120918A is soluble in the standardized formulations utilized for parenteral administration, precipitation nevertheless occurs upon injection or infusion into the blood stream. This precipitation on infusion occurs as the formulation, a weak base, mixes within the pH neutral blood stream. The novel compositions of the present Invention maintain solubility within the blood stream and prevent precipitation of the drug upon injection or infusion into the blood stream.
SUMMARY OF THE INVENTION The present Invention relates to pharmaceutical compositions that prevent or minimize precipitation upon injection or infusion; comprising: a) a safe and therapeutically effective amount of N-{4-[2-1,2,3,4-tetrahydro- 6,7-dimethoxy-2-isoquinolinyl)-ethyl]-phenyl}-9,10-dihydro-5-methoxy-9oxo-4-acridine carboxamide and its physiologically acceptable salts and solvates; b) a safe and effective amount of a surfactant; WO 96/11007 PCT/US95/12952 3 c) a buffer; and d) a pharmaceutically acceptable carrier or diluent.
DETAILED DESCRIPTION OF THE INVENTION By "safe and therapeutically effective amount," as used herein, means a sufficient amount of a drug or pharmaceutical agent to abate or reverse a multidrug-resistance response of a tissue, system or animal that is being sought by the researcher or clinician without harming the tissues of a mammal, including a human to which the drug is administered.
The compositions of the present Invention employ a safe and therapeutically effective amount of the compound N-{4-[2-1,2,3,4-tetrahydro-6,7dimethoxy-2-isoquinolinyl)-ethyl]-phenyl}-9,10-dihydro-5-methoxy-9-oxo-4acridine carboxamide (GF120918) and its physiologically acceptable salts and solvates, a safe and effective amount of a surfactant, a safe and effective amount of a buffer and a carrier or diluent suitable for pharmaceutical use. These compositions are suitable for administration to mammals, including humans through various parenteral routes. These various parenteral routes particularly include both intravenous bolus injection and intravenous infusion.
Persons who treat cancer and other diseases which become resistant to chemotherapeutic, anti-tumor compounds would use the compositions of the present Invention to resensitize multidrug-resistant cells to chemotherapeutic agents thus abating multidrug-resistance. Therefore, compositions of the present Invention may be administered in conjunction with an antitumor drug.
Examples of suitable antitumor drugs for use in conjunction with compositions of the present include, but are not limited to, Vinca alkaloids vincristine, vinblastine and vinorelbine, anthracyclines daunorubincin, doxorubicin and aclarubincin, taxol, and derivatives thereof taxotere), podophyllotixins (e.g.
etoposide and VP16), mitoxantrone, actinomycin, colchicine, gramidine D, cisplatin, cyclophosphamide, amsacrine or any other chemotherapeutic, antitumor type compounds.
Compositions of the present Invention while being given in conjunction with an antitumor drug, could also be given simultaneously with an anti-tumor drug. This type of administration is acceptable as long as the components of the composition of the present Invention and any antitumor compound given simultaneously are both physically and chemically compatible. In this instance WO 96/11007 PCT/US95/12952 4 "simultaneously" means, sequentially with little or no delay or given together from a common single container where the composition of the present Invention and the antitumor drug are physically mixed.
The medical community, particularly oncologists and other medical professionals who treat persons afflicted with tumor disease recognize that patients suffer various adverse side-effects from the administration of chemotherapeutic anti-tumor drugs. One of the most serious side effects produced by chemotherapeutic anti-tumor drugs is nausea and vomiting. Nausea and vomiting can result in severe consequences leading to increased morbidity and mortality. Compositions of the present Invention may also be administered with various drug formulations to combat side-effects produced by anti-tumor chemotherapy. These other drug formulations may be given either simultaneously or in conjunction with formulations of the present Invention. If given simultaneously by either being admixed in the same syringe for injection or admixed in the same intravenous bag or bottle for infusion the various formulations must be both physically and chemically compatible with compositions of the present Invention. If, however, the formulation given in conjunction with compositions of the present Invention or given together at the same time, but from a different container or is given by another route or given intravenously either prior to or subsequently to compositions of the present Invention physical and chemical reactivity should not be problematic.
Parenteral compositions of the present Invention must be in a sterile form.
Any of the various methods known to persons skilled in the art employed to prepare sterile parenteral preparations that will not degrade components of the present Invention are suitable for use in the compositions sterile preparation.
Parenteral compositions of the present Invention may be packaged, produced or contained in packaging materials such as single use ampoules, vials or intravenous bottles or bags or alternatively in multidose or multiuse vials or containers.
Compositions of the present Invention may also be packaged as articles of manufacture comprising a safe and therapeutically effective amount of GF120918 and its physiologically acceptable salts and solvates; a safe and effective amount of a surfactant; a buffer; and a pharmaceutically acceptable carrier or diluent, packaged as described above. The packaging material may also have labeling and information relating to the pharmaceutical composition printed thereon.
WO 96/11007 PCT/US95/12952 Additionally an article of manufacture may have a brochure, report, notice, pamphlet, or leaflet containing product information. This form of pharmaceutical product information is sometimes, in the pharmaceutical industry, called the "package insert." A package insert may be attached to or included with a pharmaceutical article of manufacture. The package insert and any article of manufacture labeling provides information relating to the pharmaceutical composition. This information and labeling provides various forms of information utilized by health care professionals and patients that describes the composition, its dosage and various other parameters required by regulatory agencies, such as the United States Food and Drug Administration.
The pH of the present compositions range from about 1 to about particularly from about 2.5 to about 4. The essential, as well as possible optional components of the compositions of the present Invention, are described in the following paragraphs.
Essential Components One of the essential components of the present Invention is GF120918 and its physiologically acceptable salts and solvates, described in International Patent Application WO 92/12132 published 23 July 1992. GF120918 is an acridine derivative that is able to reverse or reduce resistance to, increase or restore sensitivity to or improve or increase the efficacy of an chemotherapeutic agent or agents.
The amount of GF120918 administered to prevent, abate or reverse multidrug resistance in a mammal including a human will vary with the nature of the condition being treated and the age and the condition of the patient and will be ultimately at the discretion of the attendant physician or veterinarian. In general, however, doses employed for adult human treatment will typically be in the range of about 1 mg to about 10 gm per day, particularly from about 10 mg to about 1 gm per day and more particularly from about 25 mg to about 750 mg per day. The desired dose may conveniently be presented in a single dose or as divided doses administered at appropriate intervals, for example as two, three, four or more sub-doses per day.
Another of the essential components of by the present Invention is a surface-active agent or a mixture of compatible surface-active agents, sometimes referred to as surfactants. Any compatible surface-active agent is sufficient for use WO 96/11007 PCT/US95/12952 6 in the present Invention, however, nonionic surface-active agents are particularly suitable.
Nonionic surface-active agents are particularly suitable in compositions of the present Invention and can be broadly defined as compounds produced by the condensation of alkylene oxide groups (hydrophilic in nature) with an organic hydrophobic compound which may be aliphatic or alkylaromatic in nature.
Examples of suitable nonionic surfactants include, but are not limited to: pluronics, polyethylene oxide condensates of alkyl phenols, products derived from the condensation of ethylene oxide with the reaction product of propylene oxide and ethylene diamine, ethylene oxide condensates of aliphatic alcohol's, long chain tertiary amine oxides, long chain tertiary phosphine oxides, long chain dialkyl sulfoxides and mixtures of such materials.
The surface-active agent or mixtures of compatible surface-active agents can be present in the compositions of the present Invention from about 0.05% to about 20.0%, particularly from about 0.1% to about 10.0% and most particularly from about 0.5% to about 5.0% by weight of the total composition.
The surface-active agents best suited for inclusion into the present composition are: polyethylene glycol 660 hydroxystearate (SOLUTOL® polyoxyethylene castor oil derivatives (CREMOPHOR® EL, RH40, and poloxamer, polyoxyethylene alkyl ethers (CETOMACROGOL® 1000) and polyoxyethylene sorbitan fatty acid esters (POLYSORBATE® 20, 40, 60, and 80 and TWEEN® 20, 40, 60 and 80). In particular polyethylene glycol 660 hydroxystearate, polyethylene glycol, polyoxyethylene castor oil derivatives and polyoxyethylene sorbitan fatty acid esters are useful in compositions of the present Invention.
Another essential component of the present Invention is a buffer or mixture of buffers. Buffers are compounds or mixtures of compounds which if present in a solution resist changes in the pH of the solution upon the addition of small quantities of acids or bases. Further information about buffers can be found in Remington's Pharmaceutical Sciences, p. 243 45 17th ed. (1985). Examples of buffers suitable for use in compositions of the present Invention include: acetate, phosphate and glutamate.
The last essential component of the present Invention is a suitable carrier or diluent that provides an appropriate vehicle for parenteral delivery of the WO 96/11007 PCT/US95/12952 7 composition without the introduction of untoward side-effects. Persons skilled in the art will quickly realize that any carrier or diluent intended for parenteral administration that is compatible with the essential and any optional components of the present Invention will be suitable. Examples of suitable carriers and diluents include, but are not limited to: dextrose 5% in water and sterile water for injection.
Optional Components In addition to the above described essential components, the compositions of the present Invention can contain a variety of optional parenteral conventional components known to persons skilled in the art. Any optional components included in compositions of the present Invention must be physically and chemically compatible with the essential components of the present Invention.
Optional components include, but are not limited to: cosolvents, including but not limited to, polyethylene glycol (PEG) grades 200 to 600, propylene glycol (1,2propanediol), ethanol and glycerin, preservatives and agents that adjust isotonicity and osmolality. Further information concerning preservatives and agents to adjust isotonicity and osmolality can be found in Remington's Pharmaceutical Sciences, p. 1278 1280, 1455 1472, 17th ed. (1985) Optional components may also include other drugs or combinations of drugs that are physically and chemically compatible with compositions of the present Invention. Possible optional additional drugs include, but are not limited to antitumor chemotherapeutic agents, antinausents including, serotonin 5-HT3 receptor antagonists such as ondansetron and granisetron and various other antinausents such as prochlorperazine, chlorpromazine, perphenazine, thiethylperazine, triflupromazine, droperidol, methochlopramide, trimethobenzamide, dronabinol, pherergan, nabilone and methylpredinisone.
Other additional optional drugs include: antibiotics, antidepressants, antiulcer compounds, analgesics, anticholornergics, antivirals and a myriad of other drugs suitable to treat conditions that also require the administration of compositions of the present Invention.
METHOD OF MANUFACTURE The compositions of the present Invention can be made using methods and techniques that are commonly employed in preparing parenteral preparations within the pharmaceutical industry. Remington's Pharmaceutical Sciences, p.
