`
`REMARKS
`
`Immunex Corporation
`3382-US-CNT2
`
`Claims 21, 22, 23, and 35 have been amended, claims 27 and 38 have been cancelled without
`
`prejudice or disclaimer, and new claims 42-46 are presented. Applicants reserve the right to
`
`pursue cancelled or amended subject matter in one or more timely filed related applications.
`
`Support for the amendments to claims 21 and 35 can be found at page 9, line 28 of the
`
`specification as filed. The amendment to claim 22 is merely clarifying, and fully supported
`
`at, for example, p.13, line 5 of the specification. The amendment to claim 23 is also to clarify
`
`the language. New claims 42-46 are supported in the specification at, for example, page 5,
`
`line 1. No new matter has been added by way of these amendments.
`
`Rejection
`
`35 U.S.C. § 103(a)
`
`Claims 21-23, 25, 26, 28-35 and 37-40 are rejected under 35 U.S.C. § 103(a) as allegedly
`
`being obvious over Kakuta et al. (US Patent Application No. 2003/0190316), as evidenced by
`
`Moreland et al. (Ann. Intern. Med. 1999; 130:478-486). The Office Action asserts that
`
`Kakuta et al. teach that pharmaceutical compositions containing antibodies are stabilized in
`
`formulations with L-arginine (citing paragraphs [0084] and [0085]), and that it would have
`
`been obvious to a person of ordinary skill in the art to substitute the p75 TNF receptor Fe
`
`fusion protein, whose Fe region is derived from an antibody, for antibodies in the
`
`formulations of Kakuta et al. Page 3 of the Office Action. Further, the Office Action states
`
`that one of ordinary skill in the art would have had a reasonable expectation of success
`
`because of the similarity between etanercept and an antibody, and in view of the teachings of
`
`Kakuta that high stable concentrations of protein can be achieved in the presence of L(cid:173)
`
`arginine, and further in view of the high skill in the art of making liquid pharmaceutical
`
`preparations of high molecular weight proteins. However, the Office Action indicated that
`
`Claims 27, 36 and 41 are objected to as being dependent upon a rejected base claim, but
`
`would be allowable if rewritten in independent form including the relevant limitations of the
`
`base and intervening claims.
`
`Applicants gratefully acknowledge the Examiner's indication of allowable subject matter in
`
`claims 27, 36, and 41, and respectfully traverse the rejection of the remaining claims. At the
`
`outset, Applicants submit that Kakuta et al. does not teach at the cited paragraphs that
`
`5
`
`Ex. 2014-0005
`
`
`
`USSN 13/401,496
`Response to Office Action
`April21, 2014
`
`Immunex Corporation
`3382-US-CNT2
`
`pharmaceutical compositions containing antibodies can be stabilized with L-arginine.
`
`Instead, Kakuta et al. teach at paragraphs [0084] and [0085] that a basic amino acid such as
`
`L-arginine can be ''used for adjusting the pH" (Kakuta at paragraph 84).
`
`Even assuming that Kakuta et al. did suggest that L-arginine could stabilize an antibody
`
`composition (which it does not), that would still not lead one of skill to expect it would
`
`stabilize a fusion protein which contains a completely different structure with a large non(cid:173)
`
`antibody component. In other words, the teaching relating to one protein cannot simply be
`
`transferred to another protein. As can be taken from Wang et al., 1999, Int. J. Pharmaceutics,
`
`185(2):129-188 (ofrecord, cited as D15 on the IDS)
`
`"there is no single pathway to follow in the selection of a suitable
`
`stabiliser(s)" (emphasis added, Wang et al., page 178, left column, last
`
`paragraph, lines 1-10).
`
`Moreover, according to the post-published document Daugherty et al, 2006, Advanced Drug
`
`Delivery Reviews, 58, pp. 686-706 (included on the Information Disclosure Statement filed
`
`with this response), a rather wide spectrum of agents can reduce protein aggregation rates and
`
`"[s]tudies have shown that different proteins benefit from different types
`
`o[anti-aggregating [actors, consistent with the notion that the interfacial
`
`surfaces that drive interactions leading to aggregation are protein
`
`specific" (emphasis added, page 693, paragraph bridging the columns).
`
`Further,
`
`" ... the interfacial surface of each antibody drug is unique and thus
`
`requires specific fOrmulations components to provide maximal stability
`
`and retention of activity" (emphasis added, Dauherty et al., page 690,
`
`right column, first paragraph, last sentence)
`
`Hence, even very similar antibodies may differ in aggregation behaviour (Dauherty et al.,
`
`page 693, left column, penultimate paragraph, last sentence) and stability requirements,
`
`which is due to the differences in surface-exposed amino acids that mediate antigen
`
`specificity (Dauherty et al., page 690, right column, first paragraph, penultimate sentence).

`
`Nevertheless, in order to advance prosecution, the limitation of claim 27 has been written into
`
`claim 21 and 35, and claim 27 has been cancelled. As the Office Action indicated claim 27
`
`would be allowable if rewritten in independent form, Applicant submits that this amendment
`
`renders the outstanding obviousness rejection moot. Applicants respectfully request
`
`withdrawal.
`
`CONCLUSION
`
`Applicants submit that the pending claims are patentable, and a favorable action is
`
`requested. Should the Examiner believe that any issues could be resolved by way of a
`
`teleconference, the Examiner is invited to telephone the undersigned representative of the
`
`Applicants, to discuss resolution thereof.
