`
`I.
`
`Applicant's Statement of the Substan ce of Inte rv iew
`
`REM A RKS
`
`Applicant thanks Examiner James D. Anderson for the courtesy extended during the
`
`interview on October 9, 2013 with Dr. Donna Robertson-Chow (Celgene Corporation, Ass ignee
`
`of the present application), Lei Zhang, M.D. (Celgene Corporat ion), Yeah-Sil Moon (allomey for
`
`Applicant), and Wei Zhang (attorney for Appl icant).
`
`Amendments to the claims and patentability of the claims were discussed during the
`
`interview. Without acqu iescing to the propriety of the rejections and solely to expedite
`
`allowance o f the application, Applicant proposed to amend independent claims 1 and 14 to rec ite
`
`that: ( I) the mantle cel l lymphoma is relapsed, refractory, or relapsed and refractory; and (2) the
`
`compound 3-( 4-amino-I-oxo-I,3-dihydro-isoindol-2-yl)-piperidine-2,6-dione (i. e. , lenalidomide)
`
`or a phannaceutical ly acceptable salt or hydrate thereof is administered for 21 days followed by
`
`seven days rest in a 28 day cycle. Applicant submitted that one skilled in the art would not have
`
`concluded that the compound thalidomide was therapeuticall y elTective in treating mantle cell
`
`lymphoma from the di sclosure of the cited references. In addition, at the time the present
`
`application was filed, the re was an unmet need in therapeutic options for mantle cell lymphoma
`
`patients, in particular those with relapsed, refractory, or re lapsed and refractory mantle cell
`
`lymphoma. Moreover, the therapeutic effect of lena lid om ide in relapsed, refractory, or relapsed
`
`and refractory mantle cell myeloma, as demonstrated in a Phase II clinical study, would have
`
`been unexpected at the time of fili ng this application.
`
`The Examiner agreed that the amended claims would likely to be allowable. Applicant
`
`submits herewith a declaration by Lei Zhang. M.D., under 37 C. F.R. § 1.132, as requested by the
`
`Examiner.

`
`C hlim Amendm ents
`
`Prior to entry of this paper, claims 1-27 were pending in this appl ication. Claims 2, I I
`
`and 12 have been canceled without prejudice. App licant reserve the right to pursue the subject
`
`matter of the canceled claims in one or more re lated applications. Claims I and 14 have been

`
`amended as indicated above. (n addition, claims 3, 13 and 18-23 have been amended in view of
`
`the amendments to claims 1 and 14 and claim cancellation. No new matter has been added.
`
`III.
`
`The Rejection Under 35 U.S.c. § 103(a) Should Be Withdrawn
`
`Claims \-26 remain rejected under 35 U.S.c. § I 03(a) as allegedly being unpatentable
`
`over Zeldis (U.S. Publication No. 200410029832 A I; "Zeldis'") in view of Damaj et al.
`
`(Leukemia , 2003, vol. 17, pages 1914-1915; "Damar), Wi lson et al. (British J of Haemaf%gy,
`
`2002, vol. 119, pages 128-130; "Wilson"), and Kaufmann el 01. (Blood, 2004, vol. 104, no. 8,
`
`pages 2269-2271; "Kaufmann"). (Office Action at 10.) Claim 27 remains rejected under
`
`35 U.S.c. § 103(a) as allegedly being unpatentable over Zeldis in view of Damaj, Wilson, and
`
`Kaufmann as applied to claims 1-26 above, and further in view of Witzig (.1. Clin. Oncol., 2005,
`
`vol. 23, no. 26, pages 6409-6414). (Id. at 19.). The Examiner acknowledges that Zeldis does not
`
`explicitly disclose treating mantle cell lymphoma with lenalidomide, but contends that it teaches
`
`that lenalidomide is more potent than thalidomide in certain biological activities. (See, e.g.,
`
`Office Action at 5, 13-15.) The Examiner then alleges that the secondary references, Damaj,
`
`Wilson and Kaufmann, teach that thalidomide is effective in mantle cell lymphoma, and
`
`therefore would have motivated a person skilled in the art to substitute lenalidomide for
`
`thalidomide to treat mantle cell lymphoma. (See, e.g., id. at 6,-7,18.)
`
`For the reasons stated in the response filed on December 4, 2012, App licant disagrees
`
`with the these rejections. Nevertheless, solely to expedite prosecution of the present application,
`
`Applicant has amended claims I and 14 to define that the mantle cell lymphoma treated with
`
`lenalidomide is relapsed, refractory, or re lapsed and refractory, and that lenalidomide is
`
`administered for 21 days followed by seven days rest in a 28 day cycle. As Applicant explained
`
`in the 1.132 declaration, one skilled in the art would not have concluded based on the disclosure
`
`ofDamaj, Wilson and Kaufmann that the compound thalidomide would be therapeuticall y
`
`effective in treating mantle cell lymphoma. In addition, the efficacy of lena lid om ide in relapsed,
`
`refractory, or relapsed and refractory mantle cell lymphoma, as demonstrated by the response
`
`rates, median duration of response and median overall survival in a Phase II clinical study, would

`Attorney Docket No. 9516· 904·999
`Response to Office Action dated Sep. 19,2013
`FiledonDec.18,2013
`
`have been unexpected and surprising at the time the claimed invention was made. See a/so the
`
`1.132 declaration enclosed herewith.
`
`Therefore, claims 1-26 are believed to be patentable over Zeldis in view of Damaj ,
`
`Wilson and Kaufmann, and the rejection unde r 35 U.S.c. § 103(a) should be withdrawn.
`
`Witzig is cited for the disclosure that among others, proteasome inhibitors represent a
`
`new treatment option for mantle cell lymphoma patient. It does not cure the deficiency of Zeldis
`
`in view of Damaj, Wilson and Kaufmann discussed above. Therefore, the rejection of claim 27
`
`under 35 U.S.C. § 103(a) should also be withd rawn.
`
`IV.
`
`The Double Patenting Rejection Should Be Withdrawn
`
`A. The claims are patentable over the clai ms of the ' 230 patent in view of Zeldis,
`Damaj, Wilson and Kaufmann
`
`Claims 1-1 6 and 18-26 are rejected on the ground of nonstatutory obviousness-type
`double patenting as allegedly being unpatentable over claims 18-26 of U.s. Patent No. 6,281,230
`(the "'230 patent") in view of Zeldis, Damaj, Wilson, and Kaufmann. (Office Action at 23.)
`
`The Examiner acknowledges that the claims of the '230 patent broadl y recite a method of
`
`treating an oncogenic or cancerous disease by adm inistering lenalidomide, but they do not recite
`
`the treatment of mantle cell lymphoma with the specific dosing regimen of lena lid om ide.
`
`Nevertheless, the Examiner contends that the teachings of Zeldis, Damaj, Wilson, and Kaufmann
`
`would teach, suggest and motivate one skilled in the art to adm inister lenalidomide to treat
`
`mantle cell lymphoma, for the reasons provided in the obviousness rejections. (Id.) Applicant
`
`respectfull y disagrees with this rejection.
`
`As acknowledged by the Examiner, none of the asserted claims of the ·230 patent recites
`
`the treatment of re lapsed, refractory, or relapsed and refractory mantie cell lymphoma, or the
`
`dosing regimen in the presen t claims. In addition, as discussed above in connection with the
`
`obviousness rej ec tion, Zeldis, Damaj, Wilson, and Kaufmann do not disclose or suggest methods
`
`of treating relapsed, refractory, or relapsed and refractory mantle cell lymphoma with the
`
`specific dosing regimen of lenalidomide as recited in the claims. Therefore, these secondary
`
`references do not cure the deficiencies of claims J 8-26 of the '230 patent. Lastly, the unexpected

`
`U.S. Pat. Appln. No. 121621,502
`Attorney Docket No. 9516·904·999
`Response to Office Action dated Scpo 19, 2013
`Filed on Dec. 18, 2013
`
`results of lenalidomide in the treatment of relapsed, refractory, or relapsed and refractory mantle
`
`cell lymphoma presented by Appl icant in the 1.132 declaration would rebut any presumption of
`
`obviousness that may have been established by the cited references.
`
`In view of the foregoing, Appl icant respectfully submits that the present claims are
`
`patentable over claims 18·26 of the ' 230 patent in view of Zeldis, Damaj, Wilson and
`
`Kaufmann.
`
`B. The claims are patentable over the claims of the '363 patent in view of Damaj
`
`Claims 1-1 5 and 18-26 are rejected on the ground of nonstatutory obviousness-type
`
`doub le patenting as allegedly being unpatentable over claims 1,7, 9-15 and 17-24 of U.S. Patent
`
`No. 7,468,363 (the "'363 patent") in view ofDamaj. (Office Action at 24.) The Exami ner
`
`acknowledges that the asserted claims of the '363 patent broadly recite a method of treating non(cid:173)
`
`Hodgkin's lymphoma and cutaneous or diffuse large B-celllymphoma by administering
`
`lenal idomide, but not the mantle cell lymphoma. (fd.) Nevertheless, the Examiner contends that
`
`mantle cell lymphoma is an aggressive B-ceillymphoma accordi ng to Damaj and also is a type
`
`or non-Hodgkin's lymphoma as described in the present application. (Jd.) Therefore, it would
`
`have been obvious to one skilled in the art to administer lenalidomide to treat mantle cell
`
`lymphoma. Applicant respectfully disagrees with this rejection.
`
`As acknowledged by the Examiner, none of the asserted claims of the ' 363 patent recites
`
`the treatment of reJapsed, refractory, or re lapsed and refractory mantle ceJllymphoma. Nor is
`
`mantle cell lymphoma disclosed in the specification of the ' 363 patent. Thus, one skilled in the
`
`art, upon reviewing the claims of the ' 363 patent, wou ld not have had a reason to particularly
`
`modify these claims to administer lenalidomide to treat relapsed, refractory, or relapsed and
`
`refractory mantle cell lymphoma. Damaj is directed to the use of thalidomide, not lenalidomide
`
`claimed in the ' 363 patent. [n addition, as di scussed earl ier in connection with the obviousness
`
`rejection, Damaj would not have led one skilled in the art to conclude that thalidomide is
`
`therapeutically effective in treating mantel ce tl lymphoma, let alone motivating the skilled
`
`person to use another compound to treat relapsed, refractory, or re lapsed and refractory mantle
`
`cell lymphoma. Therefore. Damaj does not cure the deficiency of the asserted claims of the '363

`
`patent. Lastly, the unexpected results of lenalidomide in the treatment of relapsed, refractory, or
`
`relapsed and refractory mantle cell lymphoma presented by Applicant in the 1. 132 declaration
`
`would rebut any presumption of obviousness that may have been established by the cited
`
`references.
`
`Therefore, the present claims are patentable over claims 1,7,9- 15 and 17-24 of the '363
`
`patent in view of Damaj. App licant respectfully requests that the rejections under the
`
`obviousness-type double patenting be withdrawn.
`
`CONCLUSION
`
`Appl icant respectfully submits that the present app lication is in condition for allowance.
`
`A favorable disposition to that effect is respectfully requested. Should the Examiner not agree
`
`that all claims are allowable, a further personal or telephonic interview is respectfully requested
`
`to discuss any remaini ng issues and to accelerate allowance of the above-captioned appl ication.
