FLAX, DAVID COTTA, and CYNTHIA M. HARDMAN, Administrative Patent Judges. COTTA, Administrative Patent Judge. DECISION ON APPEAL This is an appeal under 35 U.S.C. § 134 involving claims to a method for delivering drugs across the blood-brain-barrier. The Examiner rejected the claims on appeal as anticipated under 35 U.S.C. § 102(a)(1) and as obvious under 35 U.S.C. § 103(a). Oral argument was heard on January 30, 2020. We affirm. 1 We use the word “Appellant” to refer to “applicant” as defined in 37 C.F.R. § 1.42. According to Appellant, the real party in interest is 2-BBB Medicines B.V. App. Br. 3. Appeal 2019-001991 Application 14/692,422 2 STATEMENT OF THE CASE The Specification discloses that the blood brain barrier (“BBB”) comprises “physical and functional barriers within the blood vessels of the brain” that “serve to protect neurons.” Spec. ¶ 11. “These barriers . . . exclud[e], efflux[] and metaboliz[e] potential neurotoxic compounds (including plasma proteins, cytokines, antibodies, drugs, bacteria and viruses) from blood and brain.” Id. “For the uptake of essential nutrients, . . . the blood-brain barrier is equipped with specific carrier systems and uptake receptors.” Id. “Currently marketed CNS drugs are . . . usually either very small and potent water soluble compounds (~300 Da) or highly lipid soluble compounds, so that these compounds can cross the blood-brain barrier by diffusion.” Id. According to the Specification, given their size, large molecule “biopharmaceutical drugs are unlikely candidates for chemical modifications to enhance their permeability across the blood-brain barrier.” Id. Instead, biopharmaceutical drugs “rely on invasive and harmful technologies to patients, like direct and local stereotactic injections, intrathecal infusions and even (pharmacological) disruption of the blood-brain barrier.” Id. Not surprisingly, these techniques can have “severe neurological consequences.” Id. Thus, according to the Specification, “[i]nnovative CNS drug delivery technologies are . . . highly awaited.” Id. The Specification discloses, that “[i]t is an object of the invention to provide for a safe, effective and versatile approach for carrying cargo such as large proteins and liposomes containing drugs and genes across the cell membrane and across a blood-tissue barrier such as the blood-brain barrier for inter alia CNS drug targeting.” Id. ¶ 14. Appeal 2019-001991 Application 14/692,422 3 Claims 1, 4, 7, 9, 11–14, 17, 18, and 24 are on appeal. Claim 1 is representative and reads as follows: 1. A method for delivering a drug across the blood-brain barrier (BBB), comprising administering to a subject in need thereof an effective amount of a conjugate comprising: a glutathione conjugated via the thiol group in its cysteine moiety to a nanocontainer comprising lipid-polyethylene glycol (PEG) on its surface and an encapsulated drug, wherein the thiol group is conjugated to the lipid-PEG, such that the drug: (a) is delivered across the BBB, (b) accumulates to a lesser extent in at least one of lung, liver and kidney than does the drug encapsulated in a similarly administered control nanocontainer (i) which is not conjugated to a glutathione or (ii) to which the PEG alone is linked, and (c) accumulates to a greater extent in brain than does the drug encapsulated in a similarly administered control nanocontainer (i) which is not conjugated to a glutathione or (ii) to which the PEG alone is linked. App. Br. 11. The claims stand rejected as follows: Claims 1, 4, 7, 9, 11, 14, 17, and 18 were rejected under 35 U.S.C. § 102(b) as anticipated by Wang2 as evidenced by Ananda.3 Claims 1, 4, 7, 9, 11–14, 17, and 18 were rejected under 35 U.S.C. § 103(a) as obvious over the combination of Wang, Ananda, and Chong.4 2 Wang et al., US Patent No. 7,446,906, issued Nov. 4, 2008 (“Wang”). 3 Ananda et al., Analysis of Functionalization of Methoxy-PEG as Maleimide-PEG, 374 Analytical Biochemistry 231–242 (2008) (“Ananda”). 4 Chong et al., Treatment of Acute Nipah Encephalitis with Ribavirin, 49(6) Ann. Neurol. 810–813 (2001) (“Chong”). Appeal 2019-001991 Application 14/692,422 4 Claims 1, 4, 7, 9, 11–14, 17, 18, and 24 were rejected under 35 U.S.C. § 103 as obvious over the combination of Wang, Ananda, Chong, and Meyding-Lamadé.5 FINDINGS OF FACT 1. Wang discloses “a delivery system comprising a carrier or an active compound and a glutathione or a glutathione derivative grafted thereon.” Wang, 2:48–50. “[T]he active compound can pass through the blood-brain-barrier (BBB), such as brain endothelial cells, with the targeted carrier and has a cell penetration rate of about 0.01–100%.” Id. at 3:4–6. 2. Wang’s disclosed compounds comprise “a moiety comprising a vitamin E derivative or a phospholipid derivative, a polyethylene glycol (PEG) or a polyethylene glycol derivative bonded thereto, and a glutathione (GSH) or a glutathione derivative bonded to the polyethylene glycol or the polyethylene glycol derivative.” Id. at 3:7–13. 3. Wang discloses that the polyethylene glycol derivative in its genus of disclosed compounds “may comprise carboxylic acid, maleimide, PDP, amide, or biotin.” Id. at 3:58–59. 5 Meyding-Lamadé et al., Experimental Herpes Simplex Virus Encephalitis: A Combination Therapy of Acyclovir and Glucocorticoids Reduces Long- Term Magnetic Resonance Abnormalities, 9 Journal of NeuroVirology 118– 125 (2003) (“Meyding-Lamadé”). Appeal 2019-001991 Application 14/692,422 5 4. GSH includes four locations available for conjugation. This is illustrated in the below figure reproduced from Appellant’s Reply Brief. Reply Br. 2. The above figure shows that GSH includes a thiol group (“SH”), a primary amino group (“NH2”), and two electrophilic groups that are available for conjugation. Id. Of these four locations available for conjugation, two – the thiol group and the primary amino group – may react with a maleimide. Id.; see also, id. at 7. 5. Example 1 of Wang illustrates a method by which a compound comprising GSH conjugated to a PEG derivative may be prepared. The method is illustrated below: Appeal 2019-001991 Application 14/692,422 6 Wang 4:7–50. The above illustration depicts a method for preparing TPGS- Glutathione. Id. In the compound produced by the above method (compound 6), TPGS specifies d-alpha tocopheryl polyethylene glycol. Id. at 5:20–22. 6. Dr. Swann testifies that Example 1 of Wang “uses a trityl (Trt) ‘protecting’ group that requires a very strong acid – trifluoroacetic acid (TFA) – in a halogenated solvent for its removal, bypassing more Appeal 2019-001991 Application 14/692,422 7 conventional protection measures.” Swan Decl. ¶ 11 n. 8.6 Dr. Swann further testifies that “the sulfhydryl group is only deprotected in the final step, after the glutathione has been conjugated to the PEG derivative.” Id. According to Dr. Swann, “the exemplified method by which Wang conjugated PEG to glutathione demonstrates a significant effort to preserve the sulfhydryl group.” Id. ¶ 11. 7. Forman7 discloses: The tripeptide, γ-˪-glutamyl-˪-cysteinyl-glycine known as glutathione (GSH) . . . is the most important low molecular weight antioxidant synthesized in cells. It is synthesized by the sequential addition of cysteine to glutamate followed by the addition of glycine. The sulfhydryl group (-SH) of the cysteine is involved in reduction and conjugation reactions that are usually considered as the most important functions of GSH. These reactions provide the means for removal of peroxides and many xenobiotic compounds, however, GSH is also involved in regulation of the cell cycle. Forman, 2. 8. Dr. Swann testifies that “Wang’s efforts to protect the sulfhydryl group when producing a glutathione-PEG conjugate would be consistent with the efforts of a skilled artisan, who recognizes and appreciates the significance of protecting the sulfhydryl group to preserve the biological function of glutathione.” Swann Decl. ¶ 11. 6 Declaration of Peter W. Swann under 37 C.F.R. § 1.132, dated January 7, 2018 (“Swann Decl.”). 7 Forman et al., Glutathione: Overview of its Protective Roles, Measurement, and Biosynthesis, 30 Molecular Aspects of Medicine 1–12 (2009) (“Forman”). Forman was cited by Appellant as evidence that the sulfhydryl group (–SH) of the cysteine in the reduced form of GSH is involved in reactions that are usually considered the most important functions of GSH. App. Br. 7–8. Appeal 2019-001991 Application 14/692,422 8 9. Dr. Swann testifies that “a skilled person would be wary of conjugating a biologically inactive molecule such as lipid-PEG to that sulfhydryl group in the reduced form, as such a modification would be expected to significantly impair or extinguish the biological function of the glutathione.” Id. ¶ 10. 10. Ananda discloses: The reaction of maleimides with thiols is one of the best known site-specific, simple, and quantitative protein chemical modification reactions. Accordingly, maleimide-PEG reagents have evolved as the most desirable protein PEGylation reagents. Ananda, 231. 11. Ananda discloses: Proteins generally have a very limited number of reactive thiols from their cysteine residues, and accordingly these have been used for site specific PEGylation of proteins. If and when maleimide-PEG-reactive thiols are absent, the introduction of cysteine residues as the target sites by site-directed mutagenesis has also been advanced as a strategy for site-specific PEGylation reaction. Id. (internal citations omitted). 12. Wang II8 discloses: “a delivery system comprising a carrier or an active compound, and a glutathione ligand or a glutathione derivative ligand. The glutathione ligand or the glutathione derivative ligand is covalently bound to the carrier or the active compound.” Wang II 2:59–63. 13. Wang II discloses: “The sulfhydryl group (–SH) of the 8 Wang et al., US Patent No. 8,067,380, issued Nov. 29, 2011 (“Wang II”). Wang II was cited by Appellant for its disclosure of glutathione derivatives “in which ‘[t]he sulfhydryl group (–SH) of the glutathione is replaced’ with sulfonic acid (–SOOOH) or an –SR group, wherein R may comprise C1–C10 alkyl or lactoyl (-CO-CH(OH)-CH3).” App. Br. 6. Appeal 2019-001991 Application 14/692,422 9 glutathione ligand may be modified to form the glutathione derivative ligand.” Id. at 3:17–18. In one exemplary glutathione derivative ligand, “the original sulfhydryl group (–SH) of the glutathione ligand is replaced by –SR,” where “R may comprise C1-10 alkyl or lactoyl (-CO-CH(OH)-CH3).” Id. at 3:33–35. In another exemplary glutathione derivative ligand, “the original sulfhydryl group (–SH) of the glutathione ligand is replaced by sulfonic acid (–SOOOH).” Id. at 3:50–52. 14. Wang II discloses that “the active compound may pass through the blood brain barrier, such as brain endothelial cells, with a cell penetration rate of about 0.01-l00%.” Id. at 3:55–58. 15. The Examiner finds, and Appellant does not dispute, that “Wang II teaches that liposomes carrying on their surface S-derivatives of GSH are capable of binding to and cross[ing] the BBB.” Ans. 8. 16. Kannan9 discloses that “S-GSSG [S-labeled glutathione disulfide] uptake by the brain is minimal in the presence or absence of γ- glutamyl transpeptidase. Thus, although shared and specific uptake of GSSG and GSH do exist in some tissues, BBB transport appears to be specific for GSH.” Kannan 969. 17. Kannan studied the effect of S-hexyl GSH and S-octyl GSH on uptake of GSH by injecting these compounds together with tracer GSH into the intracarotid artery of male Sprague-Dawley rats. Id. at 965. Kannan 9 Kannan et al., Transport of Glutathione at Blood-Brain Barrier of the Rat: Inhibition by Glutathione Analogs and Age-Dependence, 263(3) Journal of Pharmacology and Experimental Therapeutics 964–790 (“Kannan”). Kannan was cited by the Examiner as evidence that “S-derivatives of GSH (i.e., obtained by coupling via the native thiol) retain the ability to bind the BBB transporter.” Ans. 8. Appeal 2019-001991 Application 14/692,422 10 discloses that S-hexyl GSH inhibited uptake of GSH by 76% and S-octyl GSH inhibited uptake of GSH by 79%. Id. at 966. 18. Kannan discloses: The apparent higher affinity of GSH analogs10 than GSH for this transport system suggest that it functions as a broad specificity transport system and not solely for GSH. The exact kinetic mechanism of inhibition of GSH uptake by GSH analogs remains to be determined. Although the inhibition of GSH transport may be competitive through a shared transport mechanism, an allosteric mechanism(s) has not been ruled out. Regardless of the mechanism of inhibition, the results provide strong support for the view that GSH transport across the BBB is mediated by a specific carrier system. Id. at 969. ANTICIPATION Appellant argues claims 1, 4, 7, 9, 11, 14, 17, and 18 together. App. Br. 4–7. We designate claim 1 as representative. In finding that Wang anticipates claim 1, the Examiner found that Wang disclosed “a conjugate produced by reacting GSH with DSPE-PEG- maleimide (Mal), wherein the conjugate is further incorporated into nanoliposomes, wherein the nanoliposomes encapsulate an active compound, and wherein GSH is capable of targeting the nanoliposomes to the blood-brain-barrier (BBB) via its ability to bind the GSH transporter found on the BBB.” Ans. 3–4. The Examiner further found that Wang disclosed using its composition to “deliver the active compound across the BBB to the brain.” Id. at 4. While Wang does not expressly disclose where 10 GSH analogs include S-hexyl GSH, S-octyl GSH, GSH-monoethyl ester and BSP-GSH. Kannan 965. Of these, we understand at least S-hexyl and S-octyl GSH to be derivatized at the sulfhydryl group. Appeal 2019-001991 Application 14/692,422 11 conjugation of PEG-Mal to GSH occurs, the Examiner found that the ordinary artisan would have “at once envisioned that Wang et al. teach GSH coupling to PEG-Mal via the reaction between the native thiol group of GSH and Mal group of PEG.” Id. Appellant does not dispute that Wang discloses all of the elements of claim 1 with the exception of the requirement that the lipid-PEG be conjugated to GSH “via the thiol group in [GSH’s] cysteine moiety.” See generally, App. Br.; see also generally Reply. Br. Instead, Appellant contends that the ordinary artisan would not have at once envisaged binding GSH to PEG via its native thiol group because Wang makes a “significant effort” to maintain the native thiol group and because this was consistent with the understanding in the art at the time that preservation of the thiol group was necessary to maintain the biological functioning of GSH. Reply Br. 3, 5. Accordingly, this case turns on whether the ordinary artisan would have “at once envisaged” binding GSH to PEG-Mal via GSH’s native thiol group. We have reviewed the arguments presented and the evidence of record. Based on our review, we agree with the Examiner that the ordinary artisan would have at once envisaged conjugating Wang’s PEG-Mal species to GSH via GSH’s native thiol. Wang discloses a delivery system that transports an active compound across the BBB. FF1. The delivery system comprises compounds in which GSH or a GSH derivative is conjugated to PEG or a PEG derivative. FF2. Wang specifically identifies five species of PEG derivatives, including, of particular relevance here, PEG-Mal. FF3. When PEG-Mal binds to GSH, as disclosed in Wang (see FF2, FF3), the native thiol group of GSH is one of a Appeal 2019-001991 Application 14/692,422 12 very limited number of locations where it can bind. FF4. The native thiol group would have been the natural location for conjugation to PEG-Mal and the ordinary artisan would have at once envisaged conjugating PEG-Mal to the native thiol because GSH has a thiol group and the reaction of maleimides with thiols is one of the “best known site-specific, simple, and quantitative protein chemical modification reactions.” FF10; see also FF11. In Wrigley, the Federal Circuit explained that where a “prior art reference . . . discloses a genus and the claim at issue recites a species of that genus . . . the issue of anticipation turns on whether the genus was of such a defined and limited class that one of ordinary skill in the art could ‘at once envisage’ each member of the genus.” 683 F.3d at 1361; see also Kennametal, Inc. v. Ingersoll Cutting Tool Company, 780 F.3d 1376, 1381– 1382 (Fed. Cir. 2015) (holding that a prior art reference disclosed five binding agents (one of which was ruthenium) and three coating techniques (one of which was PVD) anticipated a claim drawn to the specific combination of ruthenium and PVD). Here, Wang’s disclosure of PEG-Mal conjugated to GSH (FF2, FF3) comprises a genus of two species – PEG-Mal bound to GSH’s thiol group, and PEG-Mal bound to GSH’s primary amino group.11 FF4. Given the limited size of Wang’s PEG-Mal/GSH genus and 11 At oral argument, counsel for Appellant argued that PEG-Mal could also be conjugated to GSH by “functionaliz[ing] one of the electrophilic sites on it to make it a nucleophilic site.” Tr. 7. This argument was not made in Appellant’s briefing and is thus waived. Moreover, even if we were to consider it and credit it, these additional binding sites do not expand the genus disclosed in Wang sufficiently to change our analysis. In re Petering, 301 F.2d 676, 682 (C.C.P.A. 1962); Bristol-Myers Squibb Co. v. Ben Venue Labs., Inc., 246 F.3d 1368, 1380 (Fed. Cir. 2001) (“[T]he disclosure of a small genus may anticipate the species of that genus even if the species are not themselves recited.”). Appeal 2019-001991 Application 14/692,422 13 the knowledge in the art regarding maleimide/thiol conjugation (e.g., FF10, FF11), we agree with the Examiner that the ordinary artisan would have at once envisaged GSH bound to PEG-Mal via its native thiol from Wang’s disclosure of PEG-Mal bound to GSH. Appellant argues that the ordinary artisan would not have at once envisaged conjugating PEG-Mal to the native thiol of GSH because the native thiol was understood to be “necessary to maintain the biological functioning of GSH.” Reply Br. 5; see also, App. Br. 5. As support, Appellant cites Forman, which teaches that in GSH, “[t]he sulfhydryl group (–SH) of the cysteine is involved in reduction and conjugation reactions that are usually considered as the most important functions of GSH.” FF7. Appellant also provides the testimony of Dr. Peter Swann, who opines that in view of Forman the ordinary artisan would have been “wary of conjugating a biologically inactive molecule such as lipid-PEG to that sulfhydryl group in the reduced form, as such a modification would be expected to significantly impair or extinguish the biological function of the glutathione.” FF9. We are not persuaded because the Examiner has presented evidence that S-derivatives of GSH – i.e., GSH in which the native thiol has not been preserved – were known to cross the BBB. In particular, Wang II discloses a delivery system in which compounds comprising S-derivatives of GSH are used to deliver active compounds across the BBB. FF12–14. The Examiner finds, and Appellant does not dispute, that “Wang II teaches that liposomes carrying on their surface S-derivatives of GSH are capable of binding to and cross[ing] the BBB.” FF15. This finding is consistent with Kannan, which found that two S-derivatives of GSH – S-hexyl GSH and S-octyl GSH – inhibited GSH Appeal 2019-001991 Application 14/692,422 14 uptake across the BBB by 76% and 79%. FF17. From this, Kannan concluded that “inhibition of GSH transport may be competitive through a shared transport mechanism.” FF18. Kannan qualified this by stating that “[t]he exact kinetic mechanism of inhibition of GSH uptake by GSH analogs remains to be determined” and “an allosteric mechanism(s) has not been ruled out.” Id. In addition, Kannan discloses that glucothione disulfide (GSSH), another S-derivative of GSH, does not cross the BBB. FF16; see also, Swaan Decl. ¶ 23 (testifying that the “conjugation of the lipid-PEG to the sulfhydryl group of glutathione would be expected to be sterically similar to the oxidized form (GSSG), in which the sulfur of the glutathione is hidden and not nucleophilic”). However, considering Kannan and Wang II together, we find that the ordinary artisan would have understood that some S-derivatives of GSH were capable of crossing the BBB. In sum, given that GSH already comprises a thiol (FF4), that thiol was well known to react with maleimides (FF10, FF11), that there are a limited number of alternative sites where PEG-Mal could conjugate to GSH (FF4), and that S-derivatives of GSH were known to cross the BBB (FF12–15, FF17–18), we agree with the Examiner that, based on Wang’s disclosure, the ordinary artisan would have at once envisioned conjugating GSH to PEG- Mal via the reaction between GSH’s native thiol and the maleimide group of PEG. This evidence is counterbalanced, to some extent, by evidence suggesting that in Wang’s Example 1, Wang made a significant effort to preserve the native thiol. See FF5–6, FF8. However, weighing all the evidence, we are not persuaded that Wang’s efforts to preserve the native thiol group in Example 1, assuming such preservation was an intent of the Example, would have prevented the ordinary artisan from at once envisaging Appeal 2019-001991 Application 14/692,422 15 PEG-Mal conjugated to GSH’s thiol group. Wang is not limited to its specific examples. See In re Mills, 470 F.2d 649, 651 (CCPA 1972) (“[A] reference is not limited to the disclosure of specific working examples.”); see also Wang 9:10–12 (“While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto.”). Accordingly, we affirm the Examiner’s rejection of claim 1. Because they were not argued separately, claims 4, 7, 9, 11, 14, 17, and 18 fall with claim 1. OBVIOUSNESS In finding claims 1, 4, 7, 9, 11–14, 17, and 18 obvious over the combination of Wang, Ananda, and Chong, the Examiner applied Wang as discussed above in connection with the Examiner’s anticipation rejection and relied upon Chong as teaching limitations recited in dependent claims 12 and 13 relating to the use of ribavirin. Ans. 5–6. Similarly, in finding claims 1, 4, 7, 9, 11–14, 17, 18, and 24 obvious over the combination of Wang, Ananda, Chong, and Meyding-Lamadé, the Examiner applied Wang as discussed above in connection with the Examiner’s anticipation rejection and relied upon Meyding-Lamadé as teaching that limitation recited in dependent claim 24 relating to the use of a glucocorticoid. Id. at 6. Appellant does not challenge the Examiner’s findings that the additional limitations recited in dependent claims 12, 13, and 24 would have been obvious over the cited art, instead arguing that it would not have been obvious to conjugate PEG-Mal to GSH via the native thiol group and that the ordinary artisan would not have expected that a compound in which a lipid-PEG was conjugated to the GSH via the native thiol group would cross the BBB. App. Br. 7–10; Reply Br. 8–9. We do not find these arguments Appeal 2019-001991 Application 14/692,422 16 persuasive. For the reasons already discussed, we agree with the Examiner that Wang anticipates the method of claim 1. We have discussed above why Wang anticipates claim 1 and “[i]t is well settled that ‘anticipation is the epitome of obviousness.’” In re McDaniel, 293 F.3d 1379, 1385 (Fed. Cir. 2002) (quoting Connell v. Sears, Roebuck & Co., 722 F.2d 1542, 1548 (Fed. Cir. 1983)). We also agree with the Examiner that the additional limitations of claims 12 and 13 would have been obvious over the combination of Wang, Ananda, and Chong and that the additional limitations of claim 24 would have been obvious over the combination of Wang, Ananda, Chong, and Meyding-Lamadé for the reasons provided by the Examiner in the Answer and Final Office Action. Ans. 5–6; Final Act. 3–5. Accordingly, we affirm the Examiner’s rejection of claims 1, 4, 7, 9, 11–14, 17, and 18 as obvious over the combination of Wang, Ananda, and Chong, and the Examiner’s rejection of claims 1, 4, 7, 9, 11–14, 17, 18, and 24 as obvious over the combination of Wang, Ananda, Chong, and Meyding-Lamadé Appeal 2019-001991 Application 14/692,422 17 CONCLUSION In summary: Claims Rejected 35 U.S.C. § Basis Affirmed Reversed 1, 4, 7, 9, 11, 14, 17, 18 102(b) Wang 1, 4, 7, 9, 11, 14, 17, 18 1, 4, 7, 9, 11– 14, 17, 18 103(a) Wang, Ananda, Chong 1, 4, 7, 9, 11–14, 17, 18 1, 4, 7, 9, 11, 14, 17, 18, 24 103(a) Wang, Ananda, Chong, Meyding- Lamadé. 1, 4, 7, 9, 11, 14, 17, 18, 24 Overall Outcome 1, 4, 7, 9, 11, 14, 17, 18, 24 AFFIRMED Copy with citationCopy as parenthetical citation
