The terms used herein are defined as follows. If a definition set forth in the present application and a definition set forth in a provisional application from which priority is claimed are in conflict, the definition in the present application shall control the meaning of the terms.
The term “effective amount” when used in connection with an active ingredient denotes an amount of the active ingredient that, when administered to a subject for treating rhinitis, produces an intended therapeutic benefit in a subject. The term “active ingredient” (used interchangeably with “active” or “active substance” or “drug”) as used herein includes mometasone or its salt and olopatadine or its salt.
In the context of present invention, the effective amount of mometasone or its salt can range from about 0.01 mg to about 10 mg or preferably from about 0.02 mg to about 5 mg.

By “salt” or “pharmaceutically acceptable salt”, it is meant those salts and esters which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, and allergic response, commensurate with a reasonable benefit to risk ratio, and effective for their intended use. Representative acid additions salts include hydrochloride, furoate, hydrobromide, sulphate, bisulphate, acetate, oxalate, valerate, oleate, palmitate, stearate, laurate, borate, benzoate, lactate, phosphate, tosylate, mesylate, citrate, maleate, fumarate, succinate, tartrate, ascorbate, glucoheptonate, lactobionate, and lauryl sulphate salts.

The pharmaceutical composition may be in the form of a solution or a suspension, but preferably the composition is in the form of a suspension (more preferably, a single phase suspension), wherein mometasone or its salt is present in particle form and olopatadine or its salt is present in dissolved form. The mometasone or its salt and olopatadine or its salt may be present at a weight ratio of about 1:3 to about 1:106, or from about 1:5 to about 1:53 or preferably from about 1:5 to about 1:36.

In one embodiment, the composition is a suspension and includes a hydrocolloid in a sufficient amount to prevent phase separation (i.e., separation of the particles and solution) after 3 or 6 months of storage at 25±2° C. and 60%±5% relative humidity (RH) or at 40±2° C. and 75%±5% RH. In one embodiment, the aqueous pharmaceutical composition is a single phase suspension which remains a single phase suspension even after 3 or 6 months of storage at 25±2° C. and 60%±5% RH or at 40±2° C. and 75%±5% RH.
In some embodiments, the present invention provides an aqueous pharmaceutical composition comprising (a) mometasone or its salt, (b) olopatadine or its salt, and (c) a fibrillar network comprising a cellulosic material. The fibrillar network may have interfibrillar spaces. In one embodiment, the interfibrillar spaces contain one or more mometasone particles. In some embodiments, the mometasone or its salt is present in particulate form having an average particle size of less than about 15 μm. In further embodiments, the mometasone particles are equidistantly, or substantially equidistantly, spaced within the fibrillar network. The average distance between adjacent mometasone particles may be spaced sufficiently to provide consistent delivery of a fixed amount (or an effective amount) of both the mometasone (or its salt) and olopatadine (or its salt), for example, for 30, 60 or 120 doses (e.g., by nasal spray administration). In some embodiments, the fibrillar network is at least partially responsible for the ability of the compositions of the present invention to provide consistent dosing of a fixed amount, or an effective amount, of the active ingredients to the target site. The olopatadine or its salt in such compositions may be in dissolved form.
The term ‘stable’ as used in connection with aqueous suspensions refers to a composition when shaken and then stored for at least 24 hours at ambient condition does not show phase separation on visual inspection. Preferably, such stable composition does not show phase separation for a period of at least 3 days, or at least 5 days, or at least 7 days. In one aspect, the ‘stable’ composition of the present invention shows, upon shaking (e.g., for 1 minute) and visual inspection, no lump formation and a total impurity content of no more than 1.0% after storage at ambient conditions (at about 25° C. and a relative humidity of about 60%) for a period of at least 6 months.
In the context of the present invention, the drug content and impurities can be determined by various analytical techniques such as HPLC, LC-MS, TLC and the like.
It was observed that when various pharmaceutical compositions for nasal administration comprising mometasone or its salt and olopatadine or its salt were prepared, the compositions generally showed physical separation in the suspension composition. This physical instability further leads to lack of dose uniformity. Surprisingly, it was found that addition of a hydrocolloid at certain concentrations (e.g. at a concentration of at least about 0.1% w/w) in the suspension composition yielded a physically stable composition (with no separation) suitable for nasal administration.

The study consisted of a screening visit, 3 single-dose treatment periods with washout periods of 7 to 14 days between dosing in each treatment period, an early withdrawal visit if applicable, and a follow-up telephone call (or visit) 1 to 7 days after completing the third treatment period.
A total of 30 subjects were randomized to 1 of 6 treatment sequences and received at least 1 dose of study drug. All 30 subjects were included in the safety analysis set and the pharmacokinetic subset. All but 2 subjects completed the study per protocol. The safety analysis set consisted of 30 subjects: 29, 29, and 30 subjects in the safety analysis set received a single dose of the fixed dose combination of mometasone furoate and olopatadine hydrochloride nasal spray, olopatadine hydrochloride nasal spray, and PATANASE® nasal spray, respectively. The pharmacokinetic subset consisted of 30 subjects: 29, 29, and 30 subjects in the pharmacokinetic subset received a single dose of the fixed dose combination of mometasone furoate and olopatadine hydrochloride nasal spray, olopatadine hydrochloride nasal spray, and PATANASE® nasal spray, respectively.
Quantifiable concentrations of olopatadine were observed until the last time point (48 hours). All 3 treatments were well tolerated. No subject died or reported a serious adverse event; and only one subject discontinued due to a treatment-emergent adverse event (mild oropharyngeal pain) in this study. Treatment-emergent adverse events and treatment-related treatment emergent adverse events were evenly distributed across the 3 treatments. All treatment-emergent adverse events were mild. There was no clinically significant effect of any of the treatments on laboratory values, vital sign measurements, or ECG parameters.
