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 .
Priority
This instant application is a 35 USC 371 National Stage filing of international application No. PCT/US21/52269 filed on 28 Sep. 2021 and claims benefit under 35 USC 119(e) to US provisional application No. 63/086,163 filed on 1 Oct. 2020.
Information Disclosure Statement
The information disclosure statements (IDSs) submitted on 30 Mar. 2023, 18 Apr. 2023, 18 Apr. 2023, 3 May 2023, and 28 Jul. 2024 have been considered by the examiner.
Claim Rejections - 35 USC § 112
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.
Claims 9 and 13 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.
In claim 9, it is not clear if the following recitations are merely examples, alternate names, abbreviations or required limitations: “(DTIC)” “(nitrogen mustard)”, “(BCNU)”, “(CCNU)”, “(ara-C)”, “(Adriamycin)”, or “(VP-16)”.
Claim 9 contains the trademark/trade names Adriamycin and VP-16. Where a trademark or trade name is used in a claim as a limitation to identify or describe a particular material or product, the claim does not comply with the requirements of 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph. See Ex parte Simpson, 218 USPQ 1020 (Bd. App. 1982). The claim scope is uncertain since the trademark or trade name cannot be used properly to identify any particular material or product. A trademark or trade name is used to identify a source of goods, and not the goods themselves. Thus, a trademark or trade name does not identify or describe the goods associated with the trademark or trade name. In the present case, the trademark/trade names are used to identify/describe pharmaceutic preparations for the treatment of cancer and, accordingly, the identification/description is indefinite.
In claim 13, the recitation of “other PSMA ligands/inhibitors” is indefinite because it is not clear what qualifies as other PSMA ligands/inhibitors, as this is neither a term of art nor clearly defined in the specification.
Claim Rejections - 35 USC § 103
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 (i.e., changing from AIA to pre-AIA ) 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 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claim(s) 1-26, 48, and 61 is/are rejected under 35 U.S.C. 103 as being unpatentable over Bander et al. (WO 2018/204477 A1; published 8 Nov. 2018; see IDS filed 30 Mar. 2023), in view of Bander et al. (WO 02/098897 A2; published 12 Dec. 2002; see attached 892; “Bander et al. II”) and Liu et al. (Cancer Res.; published 1998; see attached 892).
Bander et al. teach methods and reagents for tumor targeting with greater efficacy and less toxicity (see title). Bander et al. teach a method of treating cancer comprising a first agent couple to a first cancer therapeutic component and providing a second agent comprising a second targeting component coupled to a second therapeutic component (see abstract). The invention has devised a way to overcome the MTD of a targeted agent in order to achieve improved efficacy ([0009], [0023]). The cancer is prostate cancer, neuroendocrine cancer, breast cancer, or non-Hodgkin’s lymphoma ([0026]). Neuroendocrine tumors include carcinoid tumors, etc ([0072]). The first and second agent may target different molecular targets on the same cell or may bind to the same receptor (e.g., PSMA) expressed by the same cell type or HER1 and HER2 expressed on the same cell type ([0041]-[0042]). The first and second therapeutic component is a radionuclide selected from 177Lu, etc ([0045]-[0046]) or a chemotherapeutic agent selected from the group consisting of busulfan, etc ([0048]). Doses can range from 25% to about 100% of the MTD ([0051], [0053]). In one embodiment the first agent is J591-177Lu and the second agent is PSMA617-177Lu or PSMA I&T-177Lu ([0071]). In one embodiment the first and second component target the somatostatin receptor ([0073], [0076]) or the HER receptor family ([0078]) and the cancer is breast cancer ([0077]-[0078]). The cancer may be non-Hodgkin’s Lymphoma and the first and second component target CD20 ([0080]-[0081]). Bander et al. disclose a method of treating/imaging cancer in a subject comprising administering to the subject having cancer a composition comprising J591-177Lu (i.e. 75 µCi) and PSMA-617-177Lu (200 µCi) well below its MTD (example 2; Figs. 2, 3). (This reads on method and composition that administers to a subject having human prostate cancer cells a combination therapeutic for treating cancer comprising (i) a first targeting component coupled to a cancer therapeutic (PSMA-617-177Lu; small molecule), and (ii) a second agent comprising a second targeting component coupled to a second therapeutic component (J591-177Lu; antibody) wherein the second agent increases the uptake and internalization of the first or an targeting component wherein the first and second agents are different and target the same molecular target (PSMA) and target a cancer cell receptor.) Where the target molecule/receptor is internalized additive amounts of the 2 will therefore be internalized. If the 2 targeting agents have different properties and are non-overlapping, the 2 agents can be co-administered to result in additive binding/uptake by targeted cells without causing any added toxicity ([0104]). The tumor gets additive dosing while the non-target normal tissues do not receive additive doses ([0109]). Bander et al. teach human subjects (pg. 22).
Bander et al. do not disclose the instant methods of treating/imaging, combination therapeutic or imaging system wherein the second agent comprises a second targeting component alone such as J591. Bander et al. do not further exemplify a method optionally wherein the subject is human and optionally wherein the maximum tolerated dose of cancer therapeutic is given during the administering of the combination or a method wherein the cancer therapeutic is busulfan or wherein the subject is human. Bander et al. do not further exemplify a method wherein the cancer is a neuroendocrine cancer such as carcinoid tumors or wherein the first or second targeting components target the somatostatin receptor-2 isoform.
Bander et al. II teach modified antibodies to prostate-specific membrane antigen and uses thereof (see title). Bander et al. II teach J591 [0010], [0012]). Bander et al. II teach that the antibody can be administered alone in non-derivatized unconjugated form ([0059], [0061], [p0087) to thereby ablate or kill the PSMA-expressing cancer by e.g. antibody dependent cell killing mechanisms ([0070],[0076], [00118], [00254]). Combinations of the anti-PSMA antibody and a drug are in the scope of the invention ([0062], [0077], [0078], [00269]). Bander et al. teach internalization ([0014], [0267]).
Liu et al. teach constitutive and antibody induced internalization of prostate membrane antigen (see title). Liu et al. that in the presence of mAb J591 to PSMAext, the rate of internalization of PMSA increased up to 3-fold in a dose dependent manner reaching a maximum rate at an antibody concentration of 1-2 µg/mL (pg. 4058; Fig. 4,
It would have been obvious to a person of ordinary skill in the art before the effective filing date to modify the combinations and method of Bander et al. (combinations and methods comprising J591-177Lu and PSMA-617-177Lu for the treatment of PSMA expressing cancers) so that the second agent antibody such as J591-177Lu is administering alone in unconjugated form as in J591 without a therapeutic component as taught and made obvious by Bander et al., Bander et al. II and Liu et al. because the J591 alone would have been expected to provide simplified compositions and methods (e.g. fewer (radio)synthesis steps) wherein the J591 alone in combination with PSMA-617-177Lu would have been expected to advantageously enable additive internalization of the PSMA-617-177Lu whereby improving PSMA-617-177Lu imaging and therapy and efficacy.
It would have been obvious to a person of ordinary skill in the art before the effective filing date to further modify Bander et al. so that the first and second targeting agents target different targets on the same cell as taught by Bander et al. because it would have been expected to enable an equivalent method of treating cancer using a second agent that induces internalization of the first agent. It would have been obvious to a person of ordinary skill in the art before the effective filing date to further modify Bander et al. so that the subject is human and so that the maximum therapeutic dose of the cancer therapeutic is given during the administering as taught by Bander et al. because it would have been expected to advantageously enable maximal therapeutic efficacy optionally in human subjects. It would have been obvious to a person of ordinary skill in the art before the effective filing date to further modify Bander et al. so that the cancer therapeutic agent is a chemotherapeutic agent such as busulfan as taught by Bander et al. because it would have been expected to enable enhanced chemotherapeutic treatment of PSMA expressing cancer such as prostate cancer. It would have been obvious to a person of ordinary skill in the art before the effective filing date to further modify Bander et al. so that first and second therapeutic agent target somatostatin receptor-2 isoform and so that the cancer is a neuroendocrine cancer such as a carcinoid tumor or so that the first and second component target the HER receptor family and the cancer is breast cancer or so that the first and second component target is CD20 and cancer is non-Hodgkin’s lymphoma as taught by Bander et al. because it would have been expected to advantageously enable a simplified and equivalent combination treatments of carcinoid tumors, breast cancer, and non-Hodgkin’s lymphoma where the second agent improves internalization of the first agent.
Double Patenting
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.
