DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 112(a)
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
Claims 1, 7, 9, 10, 15, 16, 18-30 and 34 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, because the specification, while being enabling for methods of treating cancer where such treatment does not encompass the prevention of cancer, does not reasonably provide enablement for methods of treating cancer where such treatment encompasses the prevention of cancer. The specification does not enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the invention commensurate in scope with these claims.
With regard to rejections under 35 USC 112(a) or 35 USC 112, first paragraph, the following factors are considered (MPEP 2164.01(a)): a) Breadth of claims; b) Nature of invention; c) State of the prior art; d) Level of ordinary skill in the art; e) Level of predictability in the art; f) Amount of direction and guidance provided by the inventor; g) Working examples and; h) Level of experimentation needed to make or use the invention based on the content of the disclosure.
The claims are extraordinarily broad:
“A method of treating a cancer in a subject, the method comprising administering to the subject in need thereof a therapeutically effective amount of an ATR inhibitor and a therapeutically effective amount of a PARP inhibitor, wherein the cancer has been previously identified as a cancer having a loss of function of ATM, BRCA2, RNAse H2A, RNAse H2B, CDK12, or a combination thereof, or wherein the cancer has been previously identified as an ALT+ cancer” (claim 1). Dependent claims 7, 9, 10, 15 and 16 define the dosage or dosage regime. Dependent claims 18-23 and 34 further define the cancer. Dependent claims 24-29 further define the ATR inhibitor. Dependent claim 30 further defines the PARP inhibitor.
The examiner notes that the specification explicitly teaches that the instant methods of treatment encompass prevention (page 23, [0091]).
b,c) The nature of the invention is determined in part by the state of the prior art.
As even a cursory perusal of the medicinal arts reveals, they have not advanced to the point where complex diseases with a significant genetic component, such as cancer, can be said to be prevented by the simple administration of a drug combination.
d) The level of skill in the art is considered to be relatively high.
e) The level of predictability in the art is considered to be relatively low.
The basis of all modern medicine and biology is, of course, chemistry. Yet even under the best of circumstances, and more than two hundred years after Lavoisier laid the foundations of its modern practice, chemistry remains an experimental science. Neither the medicinal/biological arts nor the chemical arts upon which they are based have advanced to the point where certainty has replaced the need for clinical and/or laboratory experimentation.
Cancer is neither a simple disease, nor a single disease. While some cancers can be treated in some hosts using specific compounds, the effective treatment - let alone prevention - of various forms of cancer remains highly unpredictable in the art.
Note that the amount of guidance or direction needed to enable the invention is inversely related to the amount of knowledge in the state of the art as well as the predictability in the art (MPEP 2164.03).
f,g) The amount of direction provided by the inventor is considered to be determined by the specification and the working examples. Inventor’s data do not demonstrate that the instant methods prevent cancer.
h) It would clearly require an extraordinary - and thus undue - amount of experimentation (clinical trials, etc.) in order to determine if, in fact, the instant methods are actually efficacious in the prevention of cancer.
Claim Rejections - 35 USC § 112(b)
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claim 7 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
It is unclear how a therapeutically effective amount can also be a subtherapeutic regime (amount). This appears to be a direct contradiction in terms. Note that while an applicant may be his own lexicographer, applicant may not distort art-recognized terms. Note MPEP 2173.05(a)(III).
Clarification is in order.
Claim 9 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
The term standard in the limitation “…the lowest standard starting dosage…” is a relative term which renders the claim indefinite. The term is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. Without a clear definition of what exactly this lowest standard starting dosage might be, the metes and bounds of the claim are unclear.
Claim 10 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
The term standard in the limitation “…the lowest standard maintenance dosage…” is a relative term which renders the claim indefinite. The term is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. Without a clear definition of what exactly this lowest standard maintenance dosage might be, the metes and bounds of the claim are unclear.
Claims 26-29 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
The numbered compounds (“…43, 57, 62, [etc.]…”) are unclear because they are undefined. These compounds are members of a set of compounds which are listed in Table 1 (page 38ff) of the specification. Note, however, that incorporation by reference to a specific figure (in this case a diagramed compound) or table is permitted only in exceptional circumstances where there is no practical way to define the invention in words and where it is more concise to incorporate by reference than duplicating a drawing or table into the claim. Incorporation by reference is a necessity doctrine, not for applicant’s convenience (MPEP 2173.05(s)).
Claim Rejections - 35 USC § 112(d)
The following is a quotation of 35 U.S.C. 112(d):
(d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.
The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph:
Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.
Claim 23 is rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, fourth paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. In the present instance, the claim fails to further limit the subject matter of the claim upon which it depends (independent claim 1). The claim merely repeats a limitation already explicitly present in claim 1.
Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements.
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 1, 22, 30 and 34 are rejected under 35 U.S.C. 102(a)(1) as being clearly anticipated by Clinical Cancer Research (2017), 23(12), pp. 3097-3108, cited in the IDS.
The reference teaches that combinations of a PARP inhibitor with an ATR inhibitor, or a CHK1 inhibitor (CHK1 being a downstream kinase of ATR), were synergistic in causing tumor suppression in a BRAC2MUT patient-derived xenograft (ovarian cancer) mouse model with the PARP inhibitor/ATR inhibitor combination inducing tumor regression and in most cases complete remission (abstract; page 3100, column 1, CHK1 or ATR inhibition is synergistic with PARP inhibition; page 3103, column 1, Combination therapy is more effective than PARPi alone in a BRAC2MUT PDX model; page 3104, column 2, Discussion). Olaparib (AZD2881) is the PARP inhibitor and Ceralasertib (AZD6738) is the ATR inhibitor (page 3098, column 1, text line 15; page 3098, column 2, PDX studies).
