`
`Examiner Interview
`
`REMARKS
`
`Applicant would like to thank the Examiner for the courtesy of the telephonic interview
`
`conducted on June 19, 2014 in which the obviousness rejection of record was discussed. No
`
`agreement was reached.
`
`II.
`
`Status of the Claims
`
`As presented above, Claims 1 and 74 are amended to define that the granulated
`
`mesalamine formulation is administered without food. Support for this amendment can be found
`
`e.g., on page 4, lines 31-35 of the application as filed. No new matter is added. Claims 14, 17-
`
`20, 23-31, 70, 73, and 74 remain pending.
`
`II.
`
`Rejections under 35 U.S.C. § 103
`
`Claims 14, 17-20, 23-30, 70, 73 and 74 remain rejected under pre-AIA 35 U.S.C. §
`
`103(a) as allegedly being unpatentable over the Salix article as evidenced by Meyeroff in view
`
`of Endonurse and optionally further in view of Netdoctor. Office Action at 2-12. Claim 31 also
`
`remains rejected under pre-AIA 35 U.S.C. § 103 (a) as allegedly being unpatentable over the
`
`Salix article as evidenced by Meyeroff in view of Endonurse and optionally further in view of
`
`Netdoctor, and further in view of Fischkoff. E. at 10-12. Applicant continues to disagree for at
`
`least the reasons of record and for at least the additional reasons that follow.
`
`However, solely in the interest of expediting prosecution, and in no way acquiescing to
`
`the validity of the Examiner’s rejection, Applicant has amended claims 1 and 74 to indicate that
`
`the granulated mesalamine is administered to the subject without food.
`
`As discussed with the Examiner, unlike other 5-mesalamine drugs available at the time of
`
`the invention, Applicant has demonstrated that the claimed methods are equally safe and
`
`effective when granulated mesalamine is administered to a subject without food.
`
`The Salix article cited by the Examiner is completely silent as to the administration of the
`
`granulated mesalamine with or without food. The press release does not disclose Applicant’s
`
`discovery that the oral mesalamine formulation was equally effective when administered with or
`
`ME1 18392263v.1
`
`5
`
`
`
`Docket No.: 122184—02804
`
`Application No.: 12/573,081
`
`without food. Based on the cited art, one having ordinary skill in the art would have been unable
`
`to come to a conclusion as to the efficacy of the mesalamine formulation when administered
`
`without food. Thus, at the time of filing, one having ordinary skill in the art would have to look
`
`elsewhere for guidance as to the administration of oral mesalamine to a subject with or without
`
`food.
`
`At the time of the invention, there were at least two other oral mesalamine formulations
`
`approved by the FDA. As indicated above, the pending claims are directed to methods of
`
`administering a delayed and extended—release gal mesalamine formulation. The mesalamine
`
`formulation most similar to the one in the pending claims is Lialda®. Lialda® is a delayed and
`
`extended—release oral meslamine tablet that was approved for inducing the remission of active,
`
`mild to moderate ulcerative colitis in 1987. Specifically, Lialda® is a tablet coated with a pH
`
`dependent polymer film, which breaks down at or above pH 6.8, typically in the terminal ileum.
`
`The tablet core contains mesalamine with hydrophilic and lipophilic excipients and provides for
`
`extended release of mesalamine. Lialda® is administered as “two to four 1.2 g tablets taken
`
`once daily with food.” See e.g., the sections on page 1 and 2 of the Lialda® prescribing
`
`information (a copy of which is submitted herewith) entitled “Dosing and Administaration”.
`
`Specifically, the Dosing and Administration section on page 2 sets forth that “[t]he
`
`recommended dosage for the induction of remission in adult patients with active, mild to
`
`moderate ulcerative colitis is two to four 1.2 g tablets taken once daily with a meal for a total
`
`daily dose of 2.4 g or 4.8 g. The recommended dosage for the_maintenance of remission is two
`
`1.2 g tablets taken once daily with a meal for a total_daily dose of 2.4 g. Emphasis added.
`
`Another oral mesalamine formulation available at the time of the invention is Pentasa®.
`
`Pentasa® is a controlled release mesalamine formulation that was approved for administration to
`
`subjects having mild to moderate ulcerative colitis in 1993. Unlike granulated mesalamine,
`
`Pentasa® is not a controlled and extended—release formulation. The Pentasa® label is silent in
`
`regards to administration relative to food.
`
`As indicated above, the cited art does not teach or suggest administering granulated oral
`
`mesalamine with or without food. In fact, the press release is silent as to the need to administer
`
`granulated mesalamine with or without food. At the time of the invention, one of ordinary skill
`
`in the art would look to the teachings of the most similar formulation to determine if
`
`administration with food is required. In this case, the skilled artisan would look to the teachings
`
`ME1 18392263v.1
`
`6
`
`
`
`Docket No.: 122184—02804
`
`Application No.: 12/573,081
`
`related to Lialda® and be of the opinion that it would be necessary to administer a delayed and
`
`extended—release oral mesalamine formulation with food.
`
`However, Applicant’s specification and examples set forth the results of a clinical trial
`
`showing that there is no decrease in efficacy when granulated mesalamine is administered
`
`without food.
`
`As set forth in Example 1, Applicant determined that granulated mesalamine can be
`
`taken with or without food. Specifically, Example 1 sets forth:
`
`[t]he effect of a high fat meal intake on absorption of mesalamine granules (the
`
`same granules contained in granulated mesalamine formulation capsules) was
`
`evaluated in 30 healthy subjects. Subjects received 1.6 g of mesalamine granules
`
`in sachet (2 x 0.8 g) following an overnight fast or a high—fat meal in a crossover
`
`study. Under fed conditions, tmax for both 5—ASA and N—Ac—5—ASA was
`
`prolonged by 4 and 2 hours, respectively. A high fat meal did not affect Cmax for
`
`5—ASA, but a 27% increase in the cumulative urinary excretion of 5—ASA was
`
`observed with a high fat meal. The overall extent of absorption of N—Ac—5—ASA
`
`was not affected by a high fat meal. As granulated mesalamine formulation and
`
`mesalamine granules in sachet were bioequivalent, granulated mesalamine
`
`formulation can be taken without regard to food.
`
`Additionally, Example 4 sets forth the results of another pharmacokinetics study. This
`
`study demonstrates that
`
`the effect of food intake on 5—ASA absorption was evaluated. Healthy subjects
`
`received 1.6 g of granulated mesalamine (2 x 0.8 g) following an overnight fast or
`
`a high—fat meal in a crossover study. Tmax for both mesalamine and N—Ac—5—ASA
`
`was prolonged following a high—fat meal. Based on an 80%: 125% rule for
`
`untransformed data, the plasma Cmax for mesalamine and N—Ac—5—ASA were
`
`equivalent in fed and fasted conditions. A slight increase was seen in mesalamine
`
`AUCO_inf and AUC0_1aS[ (11% and 16%, respectively) following a high—fat meal.
`
`The overall rate and extent of absorption of mesalamine and its N-acetyl
`
`metabolite were not affected by a high—fat meal.
`
`ME1 18392263v.1
`
`
`
`Docket No.: 122184-02804
`
`Application No.: 12/573,081
`
`Accordingly, based on the clinical trial results detailed above, Applicant demonstrated
`
`that, unlike the closest mesalamine formulation available in the art, the claimed granulated
`
`mesalamine extended release oral formulations can be administered without food.
`
`The cited art, including the Salix Press Release and the secondary reference cited by the
`
`Examiner do not teach or suggest that the claimed formulation of granulated mesalamine could
`
`be effectively administered in the absence. In fact, each of the cited references is completely
`
`silent as to the administration of mesalamine with food.
`
`For at least these reasons, one of skill in the art would not have found the claimed
`
`methods obvious in view of the cited references and the knowledge available with regard to
`
`other delayed and extended-release £1 mesalamine formulations at the time that the instant
`
`application was filed. Applicant respectfully requests reconsideration and withdrawal of the
`
`foregoing rejection.
`
`IV.
`
`Final Remarks
`
`Applicant respectfully requests entry of the above amendment, favorable reconsideration,
`
`of this application, and the timely allowance of the pending claims. If a telephone conversation
`
`with Applicant’s agent would help expedite the prosecution of the above—identified application,
`
`the Examiner is urged to call the undersigned agent at (617) 449-6509.
