`
`
`I.
`
`1.
`
`I, Robert Earhart, M.D., Ph.D., declare as follows:
`
`Introduction
`2.
`
`I am the same Robert Earhart who submitted a declaration in support
`
`of Celltrion’s Petition for Inter Partes Review of U.S. Patent 7,892,549 (the ’549
`
`patent) in March 2017. A detailed description of my background and
`
`qualifications may be found in that declaration, which I refer to as my “first
`
`declaration.”
`
`3.
`
`I am being compensated at my standard rate for my time spent
`
`preparing this declaration, and my compensation is not contingent on the outcome
`
`of any matter or on any of the opinions provided below. I have no financial
`
`interest in the outcome of this proceeding.
`
`4.
`
`I provided my understanding of legal concepts as they relate to this
`
`proceeding in my first declaration. My understanding of those concepts has not
`
`changed since I submitted my first declaration.
`
`5.
`
`I understand that the parties have proposed different definitions for a
`
`person of ordinary skill in the art. (Petition at 43; POR at 35.) In the institution
`
`decision, the Board adopted Patent Owner’s definition, but noted that it does not
`
`discern an appreciable difference in the parties’ respective definitions. (Paper 9 at
`
`9-10.) It further noted that “both parties contend that a person of ordinary skill in
`
`the art would have had experience with breast-cancer research and treatment.” I

`

`
`
`have such experience, including experience in the evaluation of data which either
`
`support or reject the decision to conduct a clinical trial to administer anticancer
`
`treatments in adult patients with solid tumors. My own professional experience of
`
`40 years in strategic clinical program design, protocol development, clinical study
`
`monitoring and conduct under Good Clinical Practice principles, clinical data
`
`analysis, manuscript and report generation, analysis of published clinical trial
`
`reports, and teaching of principles in the field of oncology drug development have
`
`provided me with an intimate understanding of the processes and standards by
`
`which such a person of ordinary skill in the art decides that a given course of
`
`clinical trial development is obvious. I have reviewed both definitions and to the
`
`extent there are difference, those differences do not affect the opinions set forth in
`
`either my first declaration or this declaration.
`
`II. A Person of Ordinary Skill in the Art Would Have Used Standard
`Principles of Combination Therapy with Antibodies
`6.
`
`As discussed in my first declaration, a person of ordinary skill in the
`
`art would have used the principles of combination therapy with antibodies like
`
`trastuzumab, because these principles provided a framework to facilitate clinical
`
`development of combination regimens of anticancer agents. Dr. Susan
`
`Tannenbaum, one of Patent Owner’s experts, argued that these principles were
`
`limited to traditional chemotherapy agents (Ex. 2062 (Tannenbaum Decl.) at
`
`¶ 199), but nothing in the prior art suggests that. The prior art taught that these
`
`
`
`2
`
`
`
`3 of 22
`
`Celltrion, Inc. 1054
`Celltrion v. Genentech
`IPR2017-01122
`
`

`

`
`
`principles “should continue to be used in the design of new regimens” with agents
`
`that showed “demonstrated antitumor activity.” (Ex. 1016 (Abeloff) at 204.)
`
`Throughout my career in drug development, these principles have provided useful
`
`guidance to the construction of successful combination regimens for cancer
`
`treatment, and neglect of these principles has often resulted in failure of well-
`
`intentioned clinical trials to produce advances in the field. Given the promise
`
`shown by trastuzumab, a person of ordinary skill in the art would have been
`
`motivated to use these well recognized principles to develop combination therapies
`
`with antibodies and more traditional chemotherapy agents. Indeed, the prior art
`
`suggests that “progress will best be made by combining [monoclonal antibodies]
`
`with chemotherapy.” (Ex. 1007 (Abrams) at 1164.) I am not aware of any
`
`scientific rationale that suggests that these principles would not apply to the
`
`combination of chemotherapy agents and antibodies.
`
`7.
`
`Given that the prior art taught the promise of antibody therapy in
`
`treating cancer and that the best progress would likely be made in using antibodies
`
`in conjunction with chemotherapy agents, a person of ordinary skill in the art
`
`would have been motivated to pursue combination therapies, and would have used
`
`the well-established principles of combining chemotherapy agents because those
`
`principles provided an adaptable framework with proven success.

`

`
`
`III. A Person of Ordinary Skill in the Art Would Have Relied on
`Preclinical Data Regarding Safety and Efficacy
`8.
`
`Preclinical data provides necessary information regarding the safety
`
`and efficacy of anticancer agents and combination therapies. Information
`
`regarding safe starting dosing, as well as acute toxicity, from preclinical studies is
`
`a necessary step prior to clinical testing in human subjects. This is particularly true
`
`with anticancer agents, which are known to have high degrees of toxicity. (Ex.
`
`1053 (Teicher) at 233-35.) Indeed, the FDA would likely not approve the use in
`
`humans of any drug that had not been shown to be sufficiently effective and safe in
`
`preclinical models. (Ex. 1053 (Teicher) at 295.) That being said, when each
`
`element of a combination therapy had previously been shown to be safe and
`
`effective on its own in clinical studies, it would not be necessary to run preclinical
`
`studies on the combination. (See, e.g., Ex. 1004 (De Vita) at 12 of 122
`
`(“Development of new treatments is based on the effectiveness of the cancer drugs
`
`in rodent models. Combinations of drugs are fashioned based on the effectiveness,
`
`the level of cross-resistance, and the limiting toxicity of the available drugs when
`
`used alone in similar patient populations.”).)
`
`9.
`
`Dr. Robert S. Kerbel, one of Patent Owner’s experts, argued that the
`
`xenografts discussed in Baselga 1996 were of limited utility because the tumors were
`
`injected subcutaneously rather than orthotopically. (Ex. 2061 (Kerbel Decl.) at ¶¶
`
`77-81.) A person of ordinary skill in the art would not have considered the
`
`
`
`4
`
`
`
`5 of 22
`
`Celltrion, Inc. 1054
`Celltrion v. Genentech
`IPR2017-01122
`
`

`

`
`
`location of the tumor injection to be important, because while both methods had
`
`advantages and disadvantages, both were reliable and routinely used. In my
`
`experience, no person of ordinary skill in the art would question the validity of
`
`subcutaneous xenograft studies in comparing proposed combination treatment
`
`regimens. I agree with Dr. Kerbel that in the 1990s subcutaneous testing was more
`
`common than orthotopic (Ex. 1040 (Kerbel), 26:24-27:4), and it remains more
`
`common today. Regardless, since all of the agents tested by Baselga were tested
`
`subcutaneously, it is proper and useful to compare the data for the efficacy of those
`
`agents with each other as all of the tests were done in the same manner.
`
`10. Both Dr. Kerbel and Dr. Tannenbaum criticize Baselga Abstract 53
`
`for using the BT-474 cell line, which overexpress HER2 genes at a higher rate than
`
`what is found in biopsies from patients with HER2+ breast cancer. (Ex. 2061
`
`(Kerbel) at ¶ 62; Ex. 2062 (Tannenbaum) at ¶ 161.) However, a higher rate of
`
`HER2 gene expression is advantageous, rather than detrimental, to the research
`
`process as high level of HER2 expression correlated with poor treatment outcomes.
`
`A person of ordinary skill in the art would consider positive results using the BT-
`
`474 cell line as a motivation to pursue the tested agent. Further, because all of
`
`agents were compared using the same cell lines, the data are properly comparable.
`
`11. The prior art regarding the clinical efficacy of each of trastuzumab
`
`and paclitaxel in humans, i.e., “the species of interest,” and the satisfaction of the
`
`
`
`5
`
`
`
`6 of 22
`
`Celltrion, Inc. 1054
`Celltrion v. Genentech
`IPR2017-01122
`
`

`

`
`
`other principles of combination therapy that I described in my first declaration,
`
`would have motivated a person of ordinary skill in the art to pursue the clinical use
`
`of the combination of paclitaxel and trastuzumab. Because of the positive clinical
`
`data, preclinical results are not necessary before using the combination in humans.
`
`But, the presence of this preclinical data certainly bolsters the motivation to treat
`
`patients with the trastuzumab/paclitaxel combination.
`
`IV. A Person of Ordinary Skill in the Art Would Have Been Motivated
`to Use the Combination of Paclitaxel and Trastuzumab
`12. Dr. Tannenbaum argued that paclitaxel’s approval as a second line
`
`therapy would have given clinicians pause in using it, because “the fact that
`
`paclitaxel was not approved as a first-line treatment suggests that it is not as
`
`efficacious as other treatments and/or there are other reasons (such as toxicity)
`
`limiting paclitaxel to second-line treatments.” (Ex. 2062 (Tannenbaum Decl.) at
`
`¶ 191).) I disagree. First, doctors used paclitaxel as a first-line therapeutic despite
`
`the labelled indication, and the prior art taught that paclitaxel was “highly active as
`
`initial therapy for metastatic breast cancer.” (Ex. 1039 (Reichman) at 1943.)
`
`Paclitaxel also showed efficacy in patients who had anthracycline resistant
`
`metastatic breast cancer. (Ex. 2013 (Dombernowsky) at 14.) Further, the second
`
`line approval for paclitaxel is merely a reflection of how the sponsor of that drug,
`
`Bristol-Myers Squib, performed its clinical trials and not any belief about its
`
`relative efficacy. Paclitaxel had also shown “excellent activity” both in xenografts
`
`
`
`6
`
`
`
`7 of 22
`
`Celltrion, Inc. 1054
`Celltrion v. Genentech
`IPR2017-01122
`
`

`

`
`
`and in breast cancer patients. (Ex. 1053 (Teicher), 112-14; Ex. 1007 (Abrams),
`
`1164; Ex. 1011 (Seidman 1996).)
`
`13. Additionally, a person of ordinary skill in the art would not have
`
`been discouraged in using paclitaxel due to the hypersensitivity reactions that
`
`sometimes occurred. Hypersensitivity reactions, which at the time of the alleged
`
`invention were thought most likely to be related to vehicle rather than the taxane,
`
`are well recognized to be different from allergic reactions that occur with other
`
`agents. (Ex. 1006 (DeVita) at 415.) The prior art taught how to limit these
`
`reactions and that a patient who did suffer from them could be successfully
`
`retreated even after a major hypersensitivity reaction. (Ex. 1007 (Abrams) at 1156;
`
`Ex. 2014 (Fisherman) at 780.) True allergic reactions are mediated by IgE and are
`
`likely to be more severe if the sufferer is exposed repeatedly to the offending
`
`allergen. Vehicle-mediated histamine release reactions, known as hypersensitivity
`
`reactions, can be blunted or eliminated by brief pretreatment with corticosteroids,
`
`and do not contraindicate subsequent administration of taxanes. Neutropenia,
`
`another potential side effect, was predictable and transient in nature, much less
`
`significant with paclitaxel than with docetaxel, and treatable with administration of
`
`G-CSF agents such as filgrastim (Neupogen®) or with prophylactic oral
`
`antibiotics, and the other side effects were generally not dose-limiting. (Ex. 1004
`
`(DeVita) at 50-51.) Given that without treatment, patients with HER2+ metastatic
`
`
`
`7
`
`
`

`Celltrion, Inc. 1054

`IPR2017-01122
`
`

`

`
`
`breast cancer have a very short life expectancy, these reactions were well within
`
`the bounds of accepted and acceptable risks associated with chemotherapy in
`
`general and did not limit the use of paclitaxel.
`
`14. Dr. Tannenbaum also argues that a later publication by the authors of
`
`Seidman 1996 contradict what Seidman 1996 taught regarding the efficacy of
`
`paclitaxel in HER2+ breast cancer patients and that a person of ordinary skill in the
`
`art therefore would not have relied on Seidman 1996. (Ex. 2062 (Tannenbaum
`
`Decl.) at ¶ 183.) Logically, the later article, published in 2002 (see Ex. 2024 (Van
`
`Poznak)), could not have informed the opinion of a person of ordinary skill in the
`
`art in 1996.
`
`15. A close reading of Van Poznak (Ex. 2024) confirms that the later
`
`paper did not negate the finding that HER2+ patients are sensitive to paclitaxel.
`
`Instead, the paper suggests that the results may be “partly in contrast” to their
`
`earlier results. (Ex. 2024 (Van Poznak) at 2323.) Van Poznak hypothesizes that
`
`some of the difference may be attributable to different methods of detecting
`
`whether a sample is HER2+ (id. at 2323-24), and restates its earlier finding: “[o]ur
`
`prior assessment of tumor HER2 expression through monoclonal antibody (4D5)
`
`and the polyclonal antibody (pAB-1) demonstrated that 4D5 positivity was
`
`predictive of positive response to taxane monotherapy.” (Id. at 2320.) If Van
`
`Poznak and Seidman et al. had been convinced that their earlier-reported data was
`
`
`
`8
`
`
`
`9 of 22
`
`Celltrion, Inc. 1054
`Celltrion v. Genentech
`IPR2017-01122
`
`

`

`
`
`incorrect, a POSA would have expected to see a clear statement disavowing their
`
`earlier conclusion.
`
`16. Dr. Tannenbaum criticizes Seidman 1996, stating that it is only an
`
`abstract and is therefore not as reliable as “a more fulsome analysis in a peer-
`
`reviewed journal.” (Ex. 2062 (Tannenbaum Decl.) at ¶ 154.) I disagree with Dr.
`
`Tannenbaum that the abstract format of the reference affects its reliability. Peer
`
`review is most important for analysis and discussion. It is not as important for
`
`short reports of data. The Seidman 1996 abstract simply reports the facts as its
`
`authors observed them: HER2+ patients were sensitive to taxanes. There is no
`
`editorial and no analysis that needs peer review. Absent any allegation of
`
`misconduct on the part of the authors, a person of ordinary skill in the art would
`
`have had no reason to doubt their reported data.
`
`17. Dr. Tannenbaum also argues that a person of ordinary skill in the art
`
`would have been dissuaded from pursuing a combination therapy involving
`
`paclitaxel for patients with HER2+ breast cancer based on Yu (Ex. 2029). (Ex.
`
`2062 (Tannenbaum) at ¶ 58.) In Yu, paclitaxel was tested using cell lines growing
`
`on culture plates. (Ex. 2029 (Yu) at 1360-62.) Cell-line-based in vitro research
`
`such as that reported in Yu is useful for examining specific biochemical questions,
`
`but is less predictive of clinical efficacy than are in vivo tumors of mouse origin,
`
`which in turn are not as good as human cell lines in xenograft models, which in
`
`
`
`9
`
`
`

`
`Celltrion, Inc. 1054
`Celltrion v. Genentech
`IPR2017-01122
`
`

`

`
`
`turn are not as good as clinical trial data in the species of interest (humans). In this
`
`study, the cells were modified by the introduction of foreign genetic material
`
`through an artificial plasmid construct so that they overexpressed HER2, and were
`
`then subjected to further selection to produce a population of cells with consistent
`
`expression of the artificial gene that was introduced and to have reproducible
`
`growth characteristics. Data from such studies are not regarded as definitive for
`
`conclusions about human clinical trials. That is possibly why Genentech
`
`apparently disregarded these results at the time, and did not terminate their ongoing
`
`clinical trial.
`
`V. A Person of Ordinary Skill in the Art Would Have Known that
`Response Rate Was Correlative of Overall Survival
`18. Dr. Tannenbaum argued that the positive results reported in Baselga
`
`1996 regarding the clinical efficacy of trastuzumab would not have provided a
`
`reasonable expectation of success. (Ex. 2062 (Tannenbaum Decl.) at ¶ 222.) I
`
`disagree.
`
`19. A person of ordinary skill in the art would have been motivated to
`
`combine trastuzumab with paclitaxel, with a reasonable expectation of success that
`
`the combination would perform better than no treatment and better than paclitaxel
`
`alone, because of (1) the very low occurrence of severe adverse events with
`
`treatment with trastuzumab (Ex. 1020 (Baselga 1996) at 737-38, Table 3 (out of
`
`768 administrations, there were eleven adverse events)), in combination with (2)
`
`
`
`10
`
`
`
`11 of 22
`
`Celltrion, Inc. 1054
`Celltrion v. Genentech
`IPR2017-01122
`
`

`

`
`
`the expectation of increased efficacy over either therapy alone, and (3) the lack of
`
`overlapping toxicities. (Ex. 1019 (Baselga Abstract 53) (showing positive results
`
`for combination of trastuzumab and a taxoid); Ex. 1053 (Teicher) at 291 (“If … the
`
`new agent X, because of different dose-limiting toxicity, can be added [to the first
`
`agent] without compromising dose, there is a reasonable expectation that A + B +
`
`X will be superior to A + B.”).)
`
`20. Effective dosage amounts of trastuzumab and paclitaxel in breast
`
`cancer patients, together with TTP data, were known in the prior art. (Ex. 1020
`
`(Baselga 1996) at 740 (trastuzumab median TTP was 5.1 months); Ex. 1012 (1995
`
`PDR) at 683 (paclitaxel median TTP was 3.0 or 4.2 months, depending on dose).)
`
`A person of ordinary skill in the art would have had a reasonable expectation that
`
`adding trastuzumab would achieve an extension of TTP over paclitaxel alone based
`
`on the superior TTP of trastuzumab.
`
`21. Based on the positive results reported in the Baselga 1996 Phase II
`
`trial, a person of ordinary skill would have had a reasonable expectation that a
`
`combination treatment with paclitaxel and trastuzumab would extend the time to
`
`disease progression relative to treatment with paclitaxel and relative to no
`
`treatment. Baselga 1996 reported a response rate of 11.6%. (Ex. 1020 (Baselga) at
`
`741.) Patent Owner argued that this response rate would not have provided a
`
`person of ordinary skill in the art an expectation regarding an extension of time to
`
`
`
`11
`
`
`
`12 of 22
`
`Celltrion, Inc. 1054
`Celltrion v. Genentech
`IPR2017-01122
`
`

`

`
`
`disease progression. (POR at 9). I do not agree with Patent Owner’s assessment of
`
`endpoints and how they are used and understood in clinical trials.
`
`22. Response rate (RR), time to progression (TTP), and progression-free
`
`survival (PFS) are clinical surrogate end-points used in drug development efforts to
`
`estimate the likelihood of an improvement in overall survival (OS), which is the
`
`best proof of clinically useful activity. The clinical surrogate end-points are
`
`generally expected to correlate with OS and with each other. This means that the
`
`person of ordinary skill in the art, presented with RR data from a phase II clinical
`
`study, would expect that the data would likely correlate with TTP and OS, when
`
`the treatment is tested in further trials or used in the clinic. Further, the FDA
`
`accepts studies with RR or TTP data in lieu of overall survival data because
`
`experience has shown that these three endpoints often have a positive correlation.
`
`Indeed, a published review of FDA approvals in oncology indications between
`
`1990 and 2002 noted that response rate was accepted as a surrogate for overall
`
`survival as the basis for FDA approval in 26 of 57 approvals. Johnson JR, et al,
`
`End Points and United States Food and Drug Administration Approval of
`
`Oncology Drugs, J CLIN. ONCOL. 2003; 21:1404-1411 (Ex. 1055).
`
`23. Therefore, a person of ordinary skill in the art would have understood
`
`that the response rate results reported in Baselga were likely to correlate with an
`
`extension of time to disease progression and an increase in overall survival.

`
`
`VI. Patent Owner’s Amended Claim Language Does Not Render the
`Claim Patentable Over the Prior Art
`24.
`
`In its Motion to Amend, Patent Owner’s proposed claim amendment
`
`would specify that the comparator for the claim term “extend time to disease
`
`progression without an increase in overall severe adverse events” in the ’441
`
`patent’s claim 1 is treatment with paclitaxel alone. Similarly, Patent Owner’s
`
`proposed claim amendment would specify that the comparator for the claim term
`
`“extend time to disease progression” in the ’549 patent’s claim 11 is treatment with
`
`paclitaxel alone. I have compared Patent Owner’s reasoning set forth in the
`
`Motion to Amend regarding how the proposed claimed language is patentable over
`
`the prior art to the Patent Owner’s arguments in its response regarding the
`
`patentability of the original claim language. The explanation for the proposed
`
`amendments includes nothing that is not also included in the explanation for the
`
`existing claim. Accordingly, my opinion and analysis regarding the obviousness of
`
`the proposed amended claims is identical to my opinion and analysis regarding the
`
`obviousness of the original claims
`
`25.
`
`I have been advised that a claim amendment in an inter partes review
`
`cannot introduce new matter, and that “new matter” is defined as an addition to the
`
`claim that lacks support in the original application that led to the patent.
`
`26. With respect to the proposed amendment to the ’441 patent claims, I
`
`reviewed the specifications of the original patent applications that led to ’441
`
`
`
`13
`
`
`

`
`Celltrion, Inc. 1054
`Celltrion v. Genentech
`IPR2017-01122
`
`

`

`
`
`patent, including the citations provided by Patent Owner on pages 5-6 of the
`
`Motion to Amend in IPR2017-01121. The specifications do not support the
`
`proposed amended claim term “without an increase in overall severe adverse
`
`events” for the trastuzumab/paclitaxel combination compared to paclitaxel alone.
`
`With respect to the data provided in the specification regarding treatment of the
`
`combination compared to paclitaxel alone, the patent application states:
`
`A syndrome of myocardial dysfunction similar to that
`observed with anthracyclines was reported more
`commonly with a combined treatment of AC+H (18%
`Grade 3/4) than with AC alone (3%), T (0%), or T+H
`(2%).
`
`(Ex. 1057 (’441 File History) at 47.)
`
`27. A person of ordinary skill in the art would understand the reference
`
`to “Grade 3/4” to reference severe adverse events, as defined by the Common
`
`Toxicity Criteria scale that was in use at the time. Accordingly this passage says
`
`that severe adverse events were, in fact, more common in the
`
`paclitaxel/trastuzumab arm (T+H, 2%) than in the paclitaxel only arm (T, 0%).
`
`28. The tabular results in the original specification also show the
`
`percentage of adverse events for paclitaxel alone and for the paclitaxel/trastuzumab
`
`combination. (Ex. 1057 (’441 File History) at 47.) Whether or not this table
`
`includes all adverse events or only severe adverse events, the total number of
`
`
`

`
`

`
`

`

`
`
`adverse events for the monotherapy were more than that for the combination (59%
`
`vs. 70%, respectively). (Id.) Accordingly, a person ordinary skill in the art would
`
`not have recognized from the specification that the inventor disclosed a
`
`combination treatment of paclitaxel/trastuzumab that has fewer overall severe
`
`adverse events than paclitaxel alone.
`
`29. With respect to the proposed amendment to the ’549 patent claims, I
`
`reviewed the specifications of the original patent applications that led to ’549
`
`patent, including the citations provided by Patent Owner on pages 5-6 of the
`
`Motion to Amend in IPR2017-01122. The specifications do not support the
`
`proposed amended claim term “in an amount effective to extend the time to disease
`
`progression” for a combination of trastuzumab, paclitaxel, and a third agent,
`
`compared to paclitaxel alone. Specifically, the specification does not report any
`
`experimental data for a triple combination of agents. Accordingly, a person
`
`ordinary skill in the art would not have recognized from the specification that the
`
`inventor has possession of a triple combination treatment that extends TTP
`
`compared to paclitaxel alone.
`
`VII. Materials Considered
`In preparing this Declaration, I reviewed the declarations submitted

`
`31. The Journal of Clinical Oncology (“JCO”) is a peer-reviewed
`
`publication that is generally accepted and regarded as authoritative within the
`
`oncology field. It is generally relied on by physicians, researchers and other
`
`members of the public, including those who are interested in cancer and its
`
`treatments, and has been since 1993. I have relied on JCO throughout my career.
`
`In particular, I have relied on the documents at Exhibits 1055 and 1048, titled End
`
`Points and United States Food and Drug Administration Approval of Oncology
`
`Drugs. Another important publication was Multinational Study of the Efficacy and
`
`Safety of Humanized Anti-HER2 Monoclonal Antibody in Women Who Have
`
`HER2-Overexpressing Metastatic Breast Cancer That Has Progressed After
`
`Chemotherapy for Metastatic Disease, respectively, while preparing this
`
`Declaration. The last was a seminal study from Dr. Slamon, the champion of
`
`trastuzumab clinical development, and his group.
`
`32. The Journal Biotechnology Healthcare was a peer-reviewed
`
`publication that published between 2004 and 2012. The journal was directed to
`
`healthcare payors, and focused on articles regarding the clinical, economic, benefit
`
`design, and health policy implications of biologic medicine. The journal is

`
`archived in the United States National Library of Medicine. I have relied on the
`
`document at Exhibit 1033, titled The Off Label Conundrum, while preparing this
`
`declaration.
`
`33. The Journal of the National Comprehensive Cancer Network
`
`(“JNCCN”) is a peer reviewed publication that is generally accepted and regarded
`
`as authoritative within the oncology field. It is generally relied on by physicians,
`
`researchers and other members of the public, including those who are interested in
`
`cancer and its treatments, and has been since 2003. JNCCN is of particular value
`
`in assessing national cancer demographics and national standards in oncology
`
`practice. I have relied on JNCCN throughout my career. In particular, I have
`
`relied on the document at Exhibit 1034, titled Prevalence and Safety of Off-Label
`
`Use of Chemotherapeutic Agents in Older Breast Cancer Patients: Estimates from
`
`SEER Medicare Data, while preparing this Declaration.
`
`34. The journal Oncology, published by the Cancer Network, is a peer
`
`reviewed publication that is generally accepted and regarded as authoritative
`
`within the oncology field. It is generally relied on by physicians, researchers and
`
`other members of the public, including those who are interested in cancer and its
`
`treatments, and has been since 1987. I have relied on Oncology throughout my
`
`career. In particular, I have relied on the document at Exhibit 1043, titled HER2
`
`Overexpression and Paclitaxel Sensitivity in Breast Cancer: Therapeutic

`
`
`Implications, while preparing this Declaration. Dr. Larry Norton’s group is
`
`particularly well-known and respected in the field of breast cancer research.
`
`35. The Journal of Cancer Research is a peer reviewed publication that is
`
`generally accepted and regarded as authoritative within the oncology field. It is
`
`generally relied on by physicians, researchers and other members of the public,
`
`including those who are interested in cancer and its treatments, and has been for
`
`decades. I have relied on the Journal of Cancer Research throughout my career. In
`
`particular, I have relied on the document at Exhibit 1047, titled Recombinant
`
`Humanized Anti-HER2 Antibody (HerceptinTM) Enhances the Antitumor Activity
`
`of Paclitaxel and Doxorubicin against HER2/neu Overexpressing Human Breast
`
`Cancer Xenografts, while preparing this Declaration. This article from Dr.
`
`Norton’s research team at the University of California San Diego, published in
`
`1998, was selected in 2016 as a classic article on the occasion of the 75th
`
`anniversary of the journal Cancer Research.

`VIII. Conclusion
`
`41.
`
`For all of the reasons discussed above and stated in my first
`
`declaration, it is my opinion that the claims of the '441 patent and proposed
`
`amended claim are obvious in view of the prior art.
