Benzoquinolizine-2-carboxylic acid-containing compositions

Description

FIELD OF THE INVENTION

[0001] This invention relates to topical compositions of an antibacterial benzoquinolizine-2-carboxylic acid, incorporated either as the single therapeutic ingredient in hitherto undescribed pharmaceutical compositions, or as an ingredient in novel combination with at least one agent selected from a retinoid, an antifungal agent, another antibacterial compound and/or a steroid/non-steroid anti-inflammatory agent, to processes for preparation of the compositions, to use of the compositions in preparation of a medicament, and to a method of therapeutic or prophylactic use of such a composition for the treatment of dermal, ophthalmic, otic and nasal infections, with or without attendant inflammation.

BACKGROUND OF THE INVENTION

[0002] Topical compositions are useful for a wide range of dermal infection-originating disorders, ranging from those that are skin-related to those that are related to specific body parts, such as ophthalmic, otic and nasal disorders. The incidence and epidemiology of these different disorders is well documented in the scientific and patent literature.

[0003] The use of a benzoquinolizine-2-carboxylic acid antibacterial to treat infections represents the current state of the art in the field of dermal pharmaceutical compositions and methods of treatment. For example, a topical dermal composition containing the benzoquinolizine-2-carboxylic acid, RS-(±)-9-fluoro-6,7-dihydro-8-(4-hydroxypiperidin-1-yl)-5-methyl-1-oxo-1H,5H-benzo[i,j]quinolizine-2-carboxylic acid, is marketed by Wockhardt Limited, India under the name NADOXIN™(Nadifloxacin 1%) Cream.

[0004] Although RS-(±)-9-fluoro-6,7-dihydro-8-(4-hydroxypiperidin-1-yl)-5-methyl-1-oxo-1H,5H-benzo[i,j]quinolizine-2-carboxylic acid, from chemical considerations, belongs to the class of benzoquinolizine-2-carboxylic acids, it is classified from considerations of its antibacterial mode of inhibition of one or both of the essential Type II DNA topoisomerase enzymes viz. DNA gyrase and Topoisomerse IV, and its common quinolone core moiety, as a quinolone antibacterial, with its given name analogous in terminology to drugs like ciprofloxacin and levofloxacin.

[0005] RS-(±)-9-fluoro-6,7-dihydro-8-(4-hydroxypiperidin-1-yl)-5-methyl-1-oxo-1H,5H-benzo[i,j]quinolizine-2-carboxylic acid has also been utilized in other dermal antibiotic compositions:

[0006] ACUATIM™ Cream, Otsuka Pharmaceuticals, Japan

[0007] ACUATIM™ Lotion, Otsuka Pharmaceuticals, Japan

[0008] In the field of ophthalmic pharmaceutical formulations and methods of treatment, the current state of the art embraces the use of quinolone antibiotics such as ciprofloxacin, ofloxacin, norfloxacin, and lomefloxacin as outlined in U.S. Pat. No. 6,395,476 and WO 0018404 (PCT /US 99/22625), the contents of which are incorporated herein by reference.

[0025] Compounds disclosed in the above-cited Indian and U.S. patents and patent applications include for instance,

[0026] RS-(±)-9-fluoro-6,7-dihydro-8-(4-hydroxypiperidin-1-yl)-5-methyl-1-oxo-1H,5H-benzo[i,j]quinolizine-2-carboxylic acid, also referred herein as RS-(±)-nadifloxacin or nadifloxacin,

[0027] S-(−)-9-fluoro-6,7-dihydro-8-(4-hydroxypiperidin-1-yl)-5-methyl-1-oxo-1H,5H-benzo[i,j]quinolizine-2-carboxylic acid also referred to herein as S-(−)-nadifloxacin and hydrates thereof, and

[0028] S-(−)-9-fluoro-6,7-dihydro-8-(4-hydroxypiperidin-1-yl)-5-methyl-1-oxo-1H,5H-benzo[i,j]quinolizine-2-carboxylic acid arginine salt, also referred to herein as S-(−)-nadifloxacin arginine salt and polymorphs and hydrates thereof.

[0029] RS-nadifloxacin and S-nadifloxacin, in particular, exhibit strong antibacterial activity against Gram-positive, Gram-negative and anaerobic bacteria, resistant Gram-positive organisms such as methicillin-resistant Staphylococcus aureus (MRSA), quinolone-resistant Staphylococcus aureus, coagulase negative staphylococci, such as methicillin-resistant Staphylococcus epidermidis (MRSE), enterococci, betahemolytic streptococci and viridans group of streptococci, mycobacteria and newly emerging nosocomial pathogens such as Chryseobacterium meningosepticum, and Gram-negative pathogens such as E. coli, Klebsiella, Proteus, Serratia, Citrobacter and Pseudomonas. Recently, it has also been shown that S-(−)-nadifloxacin, in particular exhibits potent antibacterial activity against glycopeptide intermediate S. aureus (GISA), vancomycin intermediate S. aureus (VISA) and vancomycin-resistant S. aureus (VRSA).

[0030] Many Gram-positive organisms have developed significant levels of resistance to other antibiotics. About 65% of all cases of bacterial keratitis and about 85% of all cases of bacterial conjunctivitis are attributable to infection by gram-positive organisms such as those listed above. The causative organism of acne vulgaris is Propionibacterium acnes. The incidence of acne vulgaris is very high, specially among adolescents. Among new emerging diseases are pyoderma gangrenosum and necrotising fascitis. Pyoderma gangrenosum is a chronic destructive ulcerating wound disorder of unknown etiology, and pathophysiology. S. aureus is most often the infecting microorganism. Necrotising fascitis is a life threatening bacterial infection causing necrosis of the fascia, underlying skin and vasculature. It progresses rapidly, has a frightening 74% mortality and a high risk of systemic activity. The Group A beta-hemolytic streptococci (GABHS) are frequently identified in necrotising fascitis. Gonzalez M., Necrotising fascitis and gangrene of the upper extremity. Hand Clinics, 14(4), 635-645 (1998); Misago N. et.al., Necrotising fascitis due to group A Streptococci: A clinicopathology study of six patients. J. of Dermatology, 23, 876-883(1996). Another type of nacrotising fascitis involves several bacteria occurring with facultative and anaerobic bacteria. However, the infection is commonly polymicrobial in etiology (Geeham D M & Pemberton L B, Management of Wound Infection in the I.C.U. Critical Care Nursing Quarterly, 69-77, 1997, November), other causative enzymes including Clostridium, Peptococcus E. coli Pseudomonas, S. pyogenes S. aureus, S. epidermidis, S. marcescens (Douglas M, Necrotising fascitis: A nursing perspective, J. of Advanced Nursing, 24, 161-66, (1996);Gillen P B, Necrotising fascitis: Early recognition and aggressive treatment remain important, J. of Wound and Ostomy Care Nursing, 22 (5), 219-221, 1995). Bacterial resistance to antibiotics is an increasingly recurrent phenomenon. The need for pharmaceutical compositions specifically to treat infections arising from such emerging and resistant microorganisms thus assumes urgent significance.

[0031] The etiology of acne, its epidemiology, its psychosocial effects leading to impaired academic and social functioning, its effects on employment status, its consequences on the overall well-being and quality of life of the patient with acne, and the aims of treating it are described in U.S. Pat. Nos. 5,543,417 and 6,365,623 B1 and references contained therein, all of which are included herein by reference. Acne is a disease with multifactorial pathogenesis including among other factors that of proliferation of Propionibacterium acnes. Among conventional topical treatments such as the antibiotics erythromycin and esters thereof, neomycin, clindamycin and esters thereof, tetracycline or the more recent RS-(±)-9-fluoro-6,7-dihydro-8-(4-hydroxypiperidin-1-yl)-5-methyl-1-oxo-1H,5H-benzo[i,j]quinolizine-2-carboxylic acid, and anti-seborrhoeic or keratolytic agents such as benzoyl peroxide, salicylic acid, azelaic acid used for the removal of comedones in acne, are the topical retinoids such as tretinoin, isotretinoin and those listed in U.S. Pat. No. 4,717,720, U.S. Pat. No. 5,587,367 and U.S. Pat. No. 6,462,064 and references contained therein, all of which are included herein by reference. U.S. Pat. No. 5,587,367 discloses a pharmaceutical or cosmetic dermal composition containing a combination of a retinoid with a second agent, such a second agent being a sterol.

[0032] The compositions of this invention comprise a combination of an antibacterial benzoquinolizine-2-carboxylic acid such as herein described and a retinoid such as herein described resulting in a synergistic effect for the treatment of epidermic keratinization disorders, epithelial or epidermic proliferation disorders and/or disorders of the sebaceous function, for instance disorders selected from the group consisting of acne vulgaris, comedonic or polymorphic acne, acne rosaria, nodulocystic acne, acne conglobata, senile acne and secondary acnes.

[0033] Allergic inflammatory conditions of the skin are manifested by macules, papules or raised wheals involving part/s of the body. At cellular level there is a breakdown of phospholipids in the cell membrane and this gives rise to mediators like leukotrienes, platelet activating factor, prostaglandins and histamine. A steroid is generally administered to alleviate the symptoms of erythema, the immune response and the related itching which are normally associated with the above-mentioned group of bacterially-infected or invaded immunologic and/or allergic inflammatory dermal disorders. It is undesirable to use steroids alone for topical treatment for extended periods of time. Steroids can penetrate the skin and cause undesirable effects, including skin atrophy, suppression of the hypothalamic-pituitary-adrenal axis, Cushing's syndrome, glycosuria, hyperglycemia, etc. Combinations of antibacterials and steroids are disclosed in U.S. Pat. No. 4,604,384, WO 2002/039993, WO 02/30395 A1, WO 00/18404, U.S. Pat. No. 6,395,746, and WO 00/18404.

[0034] Fungal diseases refer to fungal infections, including yeast infections, of keratinized and non-keratinized epithelial tissues, for example skin, nails, mucosa and the like and includes tinea pedis, tinea capitis, tinea corporis, tinea versicolor, nail fungal diseases (distal subungual onychomycosis caused by dermatophyte infection), scalp disorders, tinea cruris, and candidiasis (cf. U.S. Pat. No. 6,075,056, incorporated herein by reference). Antifungal agents are useful in treating dermatophytoses such as trichophytid, endodermophytosis, favid and deepseated trichophytid and fungal infections such as mucocutaneous mycosis and deep-seated candidiasis (cf. WO 2000062776, incorporated herein by reference).

[0035] None of the references cited above specifically contemplates formulating a benzoquinolizine-2-carboxylic acid antibiotic in topical combination compositions using one or more ingredients selected from the group of a retinoid, an antibacterial, a steroid/non-steroid antiinflammatory agent and/or an antifungal agent.

[0036] None of the references cited above specifically contemplates formulating a benzoquinolizine-2-carboxylic acid antibiotic in a combination therapy or coformulation of a benzoquinolizine-2-carboxylic acid antibacterial agent having a high degree of activity against gram-positive bacterial with one or more antibacterial agents effective against gram-negative bacteria and/or with a retinoid, steroid/non-steroid anti-inflammatory agent and/or antifungal agent.

SUMMARY OF THE INVENTION

[0037] It is an aspect of this invention to provide topical compositions of an antibacterial benzoquinolizine-2-carboxylic acid, incorporated either as the single therapeutic ingredient in pharmaceutical compositions, or as an ingredient in combination with at least one agent selected from the group of a retinoid, an antifungal agent, an antibacterial and/or a steroid/non-steroid anti-inflammatory agent, to processes for preparation of the compositions, to use of the compositions in preparation of a medicament, and to a method of therapeutic or prophylactic use of such a composition for the treatment of dermal, ophthalmic, otic and nasal infections, with or without attendant inflammation.

DETAILED DESCRIPTION OF THE INVENTION

[0038] In accordance with this invention, any benzoquinolizine-2-carboxylic acid, antimicrobial drug or one of its chiral isomers i.e. one having a benzoquinolizine-2-carboxylic acid moiety as part of its chemical structure, can be formulated in a composition either as a single ingredient or in combination with one or more ingredients selected from the group of retinoid, an antifungal agent, an antibacterial and/or a steroid/non-steroid anti-inflammatory agent and one or more acceptable excipients, carriers, or diluents.

[0039] One embodiment of this invention relates to antibacterial benzoquinolizine-2-carboxylic acid-containing dermal compositions with at least one adjunct retinoid ingredient resulting in a synergistic effect for the treatment of epidermic keratinization disorders, epithelial or epidermic proliferation disorders and/or disorders of the sebaceous function, for instance disorders selected from the group consisting of acne vulgaris, comedonic or polymorphic acne, acne rosaria, nodulocystic acne, acne conglobata, senile acne and secondary acnes.

[0040] Another embodiment of this invention relates to antibacterial benzoquinolizine-2-carboxylic acid-containing dermal compositions with at least one steroid ingredient resulting in a synergistic effect for the treatment of bacterially infected or invaded immunologic and/or allergic inflammatory disorders, for instance selected from the group consisting of contact dermatitis, seborrhoeic dermatitis, erythema multiformae, pyodermic-related wounds and infective eczema and ophthalmic, otic or nasal disorders. The formulation of this invention has the advantages of combining an agent useful for treating the dermal and other body part/s bacterial diseases and disorders with a steroid capable of reducing the associated inflammation, with the ability to rapidly eradicate bacterial infections and eliminate the symptoms thereof, and as a consequence minimize the risk of undesirable side effects. Such a formulation would ideally deliver the antibacterial agent and the steroid to the skin and other body part/s, and maintain the combination on the skin and other body part/s for the period of time necessary to effect treatment, but minimize the penetration of the skin or other body part/s with respect to the active ingredients, thus avoiding the potential steroid effects noted above.

[0041] Still another embodiment of this invention relates to antibacterial benzoquinolizine-2-carboxylic acid-containing dermal and other body part/s compositions with at least one antifungal agent ingredient resulting in a synergistic effect for the treatment of bacterially infected fungal diseases.

[0042] An antifungal agent is any agent that prevents the growth of or kills a fungal organism such as antifungal polyene macrolides such as amphotericin B, and nystatin, azole antifungal agents such as clotrimazole, miconazole, and ketoconazole, arylmethylamine antifungal agents such as butenafine and terbinafine (cf. EP 0310122B1, incorporated herein by reference), fluorinated pyrimidines, halogenated phenolic ethers, thiocarbamates, allylamines, benzylamines. In addition, antifungal agents can be agents that interpolate fungal cell wall components or act as cell wall inhibitors. Specific antifungal agents within the scope of the invention include, without limitation, the squalene epoxidase inhibitor, butenafine, and the ergosterol biosynthesis inhibitor, miconazole.

[0043] Still another embodiment of this invention relates to an antibacterial benzoquinolizine-2-carboxylic acid-containing dermal and other body part/s compositions with at least one antifungal agent ingredient and at least one steroid resulting in a synergistic effect for the treatment of bacterially infected, inflammatory fungal diseases. WO 99/20261 (incorporated herein by reference) describes inflammation of mucosal tissue, fungus-induced mucositis and rhinositis, other fungus-induced mucositis conditions such as chronic otitis media, and methods and materials for treating them. Topical compositions are described for psoriatic infections (WO 9949835, incorporated herein by reference), and for cutaneous mycosis including candidiasis, vulvitis, etc., (JP 07233088 (incorporated herein by reference).
