Description: ANTI-COCAINE CATALYTIC ANTIBODY Background of the Invention Throughout this application, various publications are referenced by author and date. Full citations for these publications may be found listed alphabetically at the end of the specification immediately preceding Sequence Listing and the claims. The disclosures of these publications in their entireties are hereby incorporated by reference into this application m order to more fully describe the state of the art as known to those skilled therein as of the date of the invention described and claimed herein. Catalytic antibodies have unique potential for the treatment of cocaine addiction and overdose. Cocaine reinforces self-administration by inhibiting a dopamine re-uptake transporter (1) m the mesolimbocortical "reward pathway". No antagonist to cocaine is known (2) , perhaps reflecting the difficulties inherent m blocking a blocker. As an alternative to receptoi -based therapeutics, a circulating agent could interrupt the delivery of cocaine to its binding site in the brain (3) An agent such as an antibody that merely bound the drug could be depleted stoichiometncally by complex formation but an enzyme that bound drug, transformed it and released product would be available for additional binding. Catalytic antibodies, a novel class of artificial enzyme, are inducible for a wide array of reactions and their substrate specificity is programmable to small molecules such as cocaine (4) . Cocaine detoxification is particularly well suited for a catalytic antibody approach First, hydrolysis of the benzoyl ester of cocaine yields the biologically inactive products (5) ecgonme methyl ester and benzoic acid (Figure 1) . The plasma enzyme butyrylcholmesterase deactivates cocaine in humans (6) by means of this reaction. Second, acyl hydrolysis is the best studied of all antibody-catalyzed transformations (7,8) Esterase activity approaching that of natural enzymes has been reported (7) for catalytic antibodies and the large hydrophobic surface of the benzoyl ester is particularly well suited to elicit antibodies with strong binding and catalysis. It has previously described (9) the first catalytic antibodies to degrade cocaine, Mab 3B9 and Mab 6A12 The antibodies were elicited by an immunogenic conjugate (TSA 1) of a phosphonate monoester transition-state analog (Scheme 1) . The rate acceleration of these first artificial cocaine esterases (10 -10') corresponded in magnitude to their relative stabilization of the ground- state to the transition-state (~ K /KJ . Catalytic antibodies with more potent catalytic mechanisms and with higher turnover rates are possible and, it has been estimated, necessary for clinical applications. Increased activity can be pursued either through repeated hybridoma generation or through mutagenesis of catalytic antibodies in hand Howevei , sequencing of the variable domains of Mab's 3B9 and 6A12 revealed 93% homology at the complementarity determining regions (see below) . Such a lack of diversity has been noted previously for catalytic antibodies (10) and limits the opportunities for improving activity since a particular class of homologous catalytic antibodies may fail to optimize to the desired activity. A potential solution to this problem, that would not compromise the core structure of the analog, would be to vary the surfaces of the analog rendered inaccessible by attachment to carrier protein and thereby present distinct epitopes for immunorecognition. The syntheses of three analogs of cocaine hydrolysis with identical phosphonate replacements but differing constructions for the immunoconjugates is now reported. The kinetics and the structural diversity of the catalytic antibodies elicited by these analogs has been characterized. The preferred catalytic antibodies for mutagenesis studies have been identified.

There are five classes of human antibodies. Each has the same basic structure consisting of two identical polypeptides called heavy chains (molecular weight approximately 50,000 Daltons and two identical light chains, (molecular weight approximately 25,000 Daltons) . Each of the five antibody classes has a similar set of light chains and a distinct set of heavy chains. A light chain is composed of one variable and one constant domain, while a heavy chain is composed of one variable and three or more constant domains The combined variable domains of a paired light and heavy chain are known as the Fv region. The Fv determines the specificity of the immunoglobulin, the constant regions have other functions. Ammo acid sequence data indicate that each variable domain comprises three hypervanable regions or loops, called complementarity determining regions flanKed by four relatively conserved framework regions (24) The hypervanable regions have been assumed to be responsible for the binding specificity of individual antibodies and to account for the diversity of binding of antibodies as a protein class In another embodiment, the present invention provides a polypeptide comprising a light chain domain with complementarity determining region 1 having ammo acid sequence RSSXGTITXXNYAN (Seq ID No 73) , complementarity determining region 2 having ammo acid sequence XNNYRPP (Seq ID No. 74) and complementarity determining region 3 having ammo acid sequence ALWYSNHWV (Seq ID No 75) , interposed between appropπoate framework regions, said light chain domain being linked to a heavy chain domain with complementarity determining region 1 having ammo acid sequence DYNMY (Seq ID No 76) , complementarity determining region 2 having ammo acid sequence YIDPXNGXIFYNQKFXG (Seq ID No 78) and complementarity determining region 3 having ammo acid sequence GGGLFAX (Seq ID No: 78) interposed between appropriate framework regions such that said polypeptide assumes a conformation suitable for degrading cocaine . In another embodiment, the invention provides a polypeptide comprising a light chain domain with complementarity determining region 1 having amino acid sequence RSSSGTITANNYGS (Seq ID No. 40) , complementarity determining region 2 having amino acid sequence VSNNRGP (Seq ID No: 41) , complementarity determining region 3 having amino acid sequence ALWNSNHFV (Seq ID No: 42) interposed between appropriate framework regions, said light chain domain being linked to heavy chain domain with complementarity determining region 1 having amino acid sequence TYYIY { Sea ID No: 67) , complementarity determining region 2 having amino acid sequence GMNPGNGVTYFNEKFKN (Seq ID No: 68) and complementarity determining region 3 having amino acid sequence VGNLFAY (Seq ID No: 69) interposed between appropriate framework regions such that the polypeptide assumes a conformation suitable for degrading cocaine. In another embodiment, the invention provides a polypeptide comprising a light chain domain with complementarity determining region 1 having amino acid sequence RSSXSLLYXDGKTYLN (Seq ID No: 79) , complementarity determining region 2 having amino acid sequence LMSTRXS (Seq ID No: 80) and complementarity determining region 3 having amino acid sequence QXFXXYPFT (Seq ID No: 81) interposed between appropriate framework regions, said light chain domain being linked to a heavy chain domain with complementarity determining region 1 having amino acid sequence SDYAWX (Seq ID No: 82) , complementarity determining region 2 having amino acid sequence YIRXXXXTRYNPSLXS (Seq ID No: 83) and complementarity determining region 3 having amino acid sequence XHYYGXXX (Seq ID No: 84) interposed between appropriate framework regions such that the polypeptide assumes a conformation suitable for degrading cocaine. In another embodiment, the invention provides a polypeptide comprising a light chain domain with complementarity determining region 1 having amino acid sequence KSSQSLLYSDGKTYLN (Seq ID No: 43) , complementarity determining region 2 having amino acid sequence LVSKLDS (Seq ID No: 44) and complementarity determining region 3 having amino acid sequence VQGYTFPLT (Seq ID No: 45) interposed between appropriate framework regions, said light chain domain being linked to heavy chain domain with complementarity determining region 1 having amino acid sequence DHWMH (Seq ID No: 72) , complementarity determining region 2 having amino acid sequence TIDLSDTYTGYNQNFKG (Seq ID No: 71) and complementarity determining region 3 having amino acid sequence RGFDY (Seq ID No: 72) interposed between appropriate framework regions such that the polypeptide assumes a conformation suitable for degrading cocaine. The complementarity determining region of the variable domain of each of the heavy and light chains of native immunoglobulin molecules are responsible for antigen recognition and binding. It has also been discovered that biosynthetic domains mimicking the structure of the two chains of an immunoglobulin binding site may be connected by a polypeptide linker while closely approaching, retaining and often improving their collective binding properties. The binding site of the polypeptide comprises two domains, one domain comprises variable domain of an immunoglobulin light chain and the other domain comprises variable domain of an immunoglobulin heavy chain. The two domains are linked by a polypeptide. Polypeptides held the two domains in proper conformation to degrade cocaine. In a preferred embodiment , the invention provides a hybrid single polypeptide chain comprising variable fragment of a light chain and a variable fragment of an heavy chain, wherein the complementarity determining regions and the framework regions come from separate immunoglobulins . In another preferred embodiment, the present invention a humanized single chain polypeptide the framework regions are of human or mammalian origin. The use of mouse non-human antibodies have certain drawbacks particularly m repeated therapeutic regimens. Mouse antibodies, for example, do no fix human complement well, and lack other important immunoglobulin functional characteristics when used m humans. Perhaps, more importantly, antibodies contains stretches of amino acid sequences that will be immunogenic when injected into human patient Studies have shown that, after injection of a foreign antibody, the immune response elicited by a patient against an antibody can be quite strong, essentially eliminating the antibody' s therapeutic utility after an initial treatment. The present invention thus provides hybrid antibodies such as the "humanized" antibodies (e g. mouse variable regions joined to human or to other mammalian constant regions) by using recombinant DNA technology, capable of degrading cocaine. The claimed hybrid antibodies have one or more complementarity determining regions from one mammalian source, and framework regions from human or other mammalian source. The hybrid antibodies of the present invention may be produced readily by a variety of recombinant DNA techniques, with ultimate expression m transfected cells, preferably immortalized eukaryotic cells, such as myeloma or hybridoma cells Polynucleotides comprising a first sequence coding for human-like antibody framework regions and a second sequence set coding for the desired antibody complementarity determining regions can be produced synthetically or by combining appropriate DNA and genomic DNA segments. In order to improve the immunogenicity of the hybrid antibody of the present invention, the human-like immunoglobulin, called acceptor, is selected to have one of the most homologous sequences to the corresponding parts of the immunoglobulin donor. The human-like immunoglobulin framework sequence will typically have about 65% to 70% homology or more to the donor immunoglobulin framework sequences . The hybrid antibodies will typically comprise at least about 3 amino acids from the donor immunoglobulin addition to the complementarity determining regions. Usually, at least one of the amino acid immediately adjacent to the complementarity determining regions is replaced. Also, the amino acid m the human framework region of an acceptor immunoglobulin is rare for that position and the corresponding amino acid in the donor immunoglobulin is common for that position m human immunoglobulin sequences. Finally, the amino acid which is predicted to be within about 3 Angstrom of the complementarity determining region in a three-dimensional immunoglobulin model and capable of interacting with the antigen or with the complementarity determining region of the humanized antibody. When combined into an hybrid antibody, the humanized light and heavy chains or complementarity determining regions and framework regions, of the present invention will be substantially non-immunogenic in humans and retam the capacity of degrading cocaine as the donor antibody.

Hybridomas were prepared by standard methods (9, 17) . Hybridoma cells (~ 2xl0 u ) were placed either into a mouse peritoneum tnat had been pretreated with pristane or into T-150 flask cell culture. The harvested ascites or cell culture super natents were subjected to affinity chromatography on a preparative protein A HPLC column (Bio-Rad) (purity > 90% by SDS-polyacrylamide gel electrophoresis) . Samples of catalytically active antibodies were purified by anion exchange HPLC with an analytic DEAE column (TOSOH HASS TSK-gel) using 0.02 M Tris and a linear gradient pH 8.8/0.0 M NaCl to pH 7.0/0.3 M NaCl without loss of cocaine esterase activity. Protocol for binding studies (CIEIA) Plates were coated with the TSA (tethered to ovalbumin) that elicited the catalytic antibody intended for CIEIA Free TSA 4 . or the TSA-related amides 8_, 13 . , or 1_4, were tested for inhibition of antibody binding to the eliciting TSA by published protocols (20b) . Protocol for kinetic measurements Catalytic antibody m 50 mM phosphate-buffered saline pH 8.0 (except 2A10 and 6A12 at pH 7.0) was incubated with Η-cocame typically at five concentrations. At three time intervals, aliquots were acidified with cold HCl (aqueous) to a final pH of 2 and partitioned with hexane- diethyl ether (1:1) , and the organic phase was assayed by scintillation counting. Background hydrolysis was determined m otherwise identical reactions without antibody, and observed rates were corrected. Assays were performed in triplicate with standard error <10%. As a control, the release of benzoic acid was confirmed by HPLC (Perkm-Elmer) using an analytical reverse-phase C 18 column (VYDAC) with an acetonitrile-water (0.1% trifluoroacetic acid) gradient and the detector set at 220 nm. HPLC analysis of a reaction mixture without antibody showed that the methyl ester of cocaine spontaneously hydrolyzes to benzoyl ecgonine with a t ]/2 = 20 hours (pH 7) . Thus, benzoyl ecognme is not available as a benzoyl esterase substrate at the early reaction times of the Η- cocame hydrolysis assay and the release of benzoic acid is attributed solely to cocaine hydrolysis. Amino acid sequencing Light and heavy chains were separated by SDS- polyacrylamide gel electrophoresis and then electroblotted to a polyvinylidenedifluoride membrane (30) for direct NH 2 -terminal sequencing by automated Edman degradation on an Applied Biosystems 470A or 477A sequencer. To obtain internal sequence, separated bands from 2A10, 19G7, 9A3 and 15A10 were reduced with dithiothreitol, alkylated with lodoacetamide, and cleaved with trypsin (31) in IM urea, 0.05 M NH 4 HC0,, pH 8.0. The peptide fragments were extracted from the membrane, separated by HPLC (Hewlett-Packard) on a reverse-phase C4 column (VYDAC) using an acetonitrile-water (0.07% trifluoroacetic acid) gradient and sequenced. Per cloning of variable domains Mouse hybridoma cell lines producing catalytic antibodies were grown to lx 10 β cells and total RNA was prepared using a microadaptation of the guanidme thiocyanate/ phenol procedure (32) and selection on a oligo (dT) cellulose column. Degenerate and non-degenerate oligonucleotide PCR primers were designed using ammo acid sequences (2A10,15A10) or the data base of Kabat et al . (24) . Restriction endonuclease sites were incorporated into the primers at their 5' prime end to facilitate cloning. The restriction sites utilized were Eco RI , Spe I, Xba I, or Xho I. The sense and antisense oligonucleotide primers for light chain (LC) and heavy chain (HC) of each hybridoma line were as follows: For 9A3 , 19G8, 15A10, 8G4E and 8G4G LC: 5 ' -GGAATTCCACIA/TC/GICCIGGIGAA/GACIG-3 ' and 5'GCTCGAGCC/TTCA/GTGIGTIACITGA/GCA-3' .

The PCR products were purified by electrophoresis in 1.5% agarose gel. Isolated PCR products from each reaction were subcloned into Bluescript plasmid and analyzed by DNA sequence analysis for the presence of open reading frame. Nucleotide sequences were assembled using the IBI MacVector 3 0 program. EXPERIMENTAL RESULTS Synthesis of transition-state analogs Phosphonate monoesters, which stably mimic the geometry and charge distribution of the transition-state for 2nd- order ester hydrolysis by hydroxide, have yielded, in some instances, catalytic antibodies of high activity (8) . However, such analogs are also known to ldiosyncratically fail to elicit any catalytic antibodies and so the rules for analog construction must be defmed empirically (11) . Strategies to improve analog efficiency have been devised, including "bait and switch" (11) and substrate attenuation (12) , but the cost of such expedients is a divergence between analog and substrate structure which results on average in catalytic antibodies with higher values for K.,. Inhalation of vaporized cocaine yields a peak pulmonary vein concentration (13) of 10-30 μM and this is less tnan the K_, of most catalytic antibodies with esterase activity At a sub-saturating concentration of cocaine, a higher K π would result in a lower turnover rate and increase the already limiting requirement for a high k cιr Thus, the construction of a high fidelity analog that differed from cocaine only by a phosphonate replacement at the acyl group and by the incorporation of a tether foi construction of an immunogenic conjugate has been chosen Based on their distances from the locus of reaction and their separation from each other, three tether sites were chosen: at the methyl ester for analog 1, the 4 '-position of the phenyl group for analog 2 , and the tropane nitrogen for analog 3. (Figure 1) The "free TSA" corresponded to the untethered structure 4_ The synthesis of TSA 1 began with the commercially available starting material (-) -ecgonine (Figure 2 > Selective alkylation of the carboxylate salt of (-)- ecgonine with 4-azιdo-1-ιodo-butane yielded ester 5_ m 78% yield.

The unstable monophosphonate product was immediately coupled to carrier protein to yield TSA-l The analog :carrier couplmg ratio was 6:1 for bovme serum albumin (BSA) and 15.1 for ovalbumin based on the incorporation of radiolabel into protein. In support of our assignment of structure to the carrier-bound analog, an aliquot of the monophosphonate was coupled to n-amylamme to yield the expected amide 8_. Synthesis of TSA-2 . required a phenylphosphomc dichloride appropriately substituted at the 4 ' position for elaboration of a tether (Figure 3) . Silylation of 2- (p- bromophenyl) ethanol followed by transmetallation with n- butyl lithium, quenching with diethyl chlorophosphate and desilylation provided alcohol . 9a in 23% yield The tosylate of ,9_a was displaced by azide and transesterification with trimethylsilyl bromide, followed by reaction with oxalyl chloride (16) , provided the required phenylphosphomc dichloride 10 Using the tetrazole catalysis method described above, chloride 1_0 . was coupled with ecgonine methyl ester and, after the addition of methanol, the mixed diester H was obtained m 25% yield. The tether was elaborated from the azide by a sequence of reactions identical to that employed for TSA-i. For the synthesis of TSA-3 . , (Figure 4) N-norcocame was monoalkylated in 75% yield and acid hydrolysis followed by reesteπfication with acidic methanol provided alcohol 15 m 72% yield. Tetrazole-catalyzed synthesis of mixed phosphonate diester lj5 proceeded m 48% yield and the tether was elaborated from the azido moiety as described above . Generation of anti-cocaine catalytic antibodies Balb/C mice were immunized with individual analogs conjugated to BSA and high titer antisera were elicited by each antigen. Monoclonal antibodies were prepared by standard protocols (9,17) and hybridomas secreting analog-specific antibodies as determined by an enzyme- linked immunosorbent assay (ELISA) were selected. All IgG anti-analog antibodies were subcloned, propagated in ascites or cell culture flasks and purified by protein A affinity column chromatography. Catalytic antibodies were identified by their capacity to release 3 H-benzoic acid from 3 H-phenyl-cocaine . The radiolabeled benzoic acid was conveniently partitioned from 3 H-cocaine by extraction of the acidified reaction mixture into organic solvent. Hydrolysis of cocaine with commercially available carboxyl esterase provided a positive control and the production of benzoic acid was confirmed by high performance liquid chromatography. A total of nine catalytic antibodies out of 107 anti-analog antibodies were identified from 9 fusions with TSA 1 yielding 6 out of 50 and TSA 3_ yielding 2 out of 49. TSA-2. generated eight anti-analog antibodies of which one was catalytic. Catalytic antibodies were further purified by DEAE anion exchange chromatography and they retained activity. All enzymes were inhibited completely by 50 μM free TSA 4 . (see below) and the Fab portion of each antibody tested retained catalytic activity; the potent inhibitor of serum esterases, eserine (18) at 1 mM, did not inhibit the activity of any catalytic mAb and 150 μM free TSA 4 . did not inhibit the cocaine esterase activity present in serum (results not shown) . Characterization of catalytic antibodies The rate of hydrolysis of 3 H-phenyl-cocaine in the presence and absence of each monoclonal antibody as a function of substrate concentration has been determined. Production of radiolabeled benzoic acid at time points corresponding to < 5% reaction provided initial rates. A saturation kinetics and obtained a linear Lineweaver-Burk plot for each artificial enzyme has been observed. The first-order rate constants (k cat ) and Michaelis constants (K „.) of the nine catalytic antibodies ranged from 0.011 to 2.3 min 1 and from 150 to 3000 μM, respectively, as shown in Table 1. Table 1. Kinetic parameters for the hydrolysis of 3 H- cocaine by Mab's.

Assays were performed at the pH that optimized k cat /k r : in general pH 7.8; for 6A12, pH 7.4; for 2A10, pH 7.0. The rate acceleration of the most active catalytic antibody, Mab 15A10, was higher and the Michaelis constant lower then those previously reported (9) for Mab 3B9; this corresponds to almost two orders of magnitude improvement in activity at sub-saturating concentrations of cocaine. It has also been reported previously that Mab 3B9 displayed a rate acceleration commensurate with the ratio of K m to the K τ for free TSA 4_. This ratio approximates the affinity of antibody for ground-state relative to transition-state and in the case of Mab 3B9 suggested that the rate acceleration resulted primarily from transition-state stabilization (19) . The inhibition constant (KJ of free TSA A for Mab 15A10 to be 0.23 μM has been determined; the rate acceleration of this catalytic antibody (k car /k unc , ιr = 2.3xl0 4 ) significantly exceeded K-./K, (9.6 x 10 2 ) . The dissociation constant K TSA for all the catalytic antibodies by competitive inhibition enzyme immunoassay (20) has been determined (CIEIA) as shown in Table 2. Table 2.

K rSA determined by CIEIA provides a relative measure of K, and permits assay at very low concentrations of antibody. As shown in Figure 1, a log-log plot of k cac /k uncat vs K / K TSA displayed a linear relationship (r = 0.85) for 7 of the 9 catalytic antibodies, since K ^SΛ is proportional to K , the relationship k cat /k uncar ≤ K_yκ for Mab 3B9 is likelv true for all seven antibodies Mab 15A10 deviated from this line, as expected since k ^r /k uncat exceeded K m /K as described above; Mab 8G4G also apparently deviated as shown. Thus, the rate acceleration for 15A10, and perhaps 8G4G, appears too great to be solely attributed to transition-state stabilization and the participation of chemical catalysis, such as acid-base or nucleophilic catalysis, is likely. Mab 15A10 was not inhibited by the product of cocaine hydrolysis, ecgonine methyl ester, at a concentration of 1 mM Benzoic acid did inhibit with a K 1 of 250 μM However, in humans, benzoic acid plasma levels are markedly suppressed by a rapid and nearly complete conversion to hippuric acid (21) It was found that 1 mM hippuric acid did not inhibit Mab 15A10 Also, there was no inhibition from 1 mM benzoyl ecgonine, a prominent metabolite of cocaine in man (22) Inactivation of Mab 15A10 by repetitive turnover was not observed, after 6 hrs, and > 200 turnovers, the k ca remained > 95% of baseline. The presence of minimal product inhibition by ecgonine methylester was fortuitous; heterologous immunization (23) with TSA 1, 2 , and 3. and the corresponding 1, 2-aminoalcohol analogs of cocaine is planned both for its potential to minimize product inhibition and its capacity to increase the yield of active enzymes The rationale for varying the tether sites of TSA to carrier protein (BSA) was to expose unique epitopes and elect catalytic antibodies specific to each immunogen In order to assess binding specificity, the catalytic antibodies were examined by ELISA with TSA 1 , 2 , and 3_ bound to ovalbumin. Unexpectedly, two groups with broad affinities were identified, a "3B9 group" (Mab's 3B9, 6A12, 2A10, 12H1) that bound all three conjugates ana a "9A3 group" (Mab's 9A3 , 19G8, 15A10, 8G4G, 8G4E) that bound only TSA-1 and 3.. To estimate the affinities for TSA 1, 2 , and 1 within these groups relative K d 's of the corresponding amides 8_, 13 , and 18 by CIEIA has been determined As shown in Table 2, CIEIA confirmed the ELISA result, identifying the same two broad groups of catalytic antibodies The 3B9 group displayed the rank order of affinities. 8 ^ 13 > 18. The relative K d for the amide of the TSA that elicited each antibody ranged from 0 01 μM for Mab 3B9 and 6A12 to 3 μM for Mab 2A10 Mab 12H1 derived from TSA 2 showed a greater affinity for the TSAl-related amide 8 . (0 01 uM) then for the TSA2-related amide 13 . (2 uM) TSA ! could have elicited Mab 12H1 and the affinities of Mab's 3B9, 6A12 and 2A10 for JL3 are also probably sufficient for TSA 2 to have elicited them The very low affinities of the 3B9 group for the TSA3-related amide 18 suggest that TSA 3 . could not have elicited this group The 9A3 group showed a distinctly different pattern with very high affinity for TSAl-related amide 8_ and TSA3- related amide 1_8 but virtually none for TSA2-related amide JL3. Apparently, TSA-1 or TSA-2 could have elicited every member of this group, TSA-2 could not have elicited any To assess the structural diversity of the catalytic Mab's, pcr-cloning and sequencing the variable regions of the heavy and light chains of each antibody were performed. Primers were generally derived from published consensus sequences (24) The 600-700 bp per fragment from each reaction was cloned into pBluescript and independently prepared clones were sequenced in both directions. The deduced primary amino acid structures contained the N- terminal amino acid sequences derived from authentic catalytic antibody samples. Amino acid sequencing also provided primers for pcr-cloning of Mab's 2A10 and 15A10. The complementarity determining regions (CDR's) were aligned for comparison (Table 3) , and several discrete families of anti-cocaine catalytic antibodies were identified. Table 3.

DNA of V H was digested by Nde I and Sphl , and introduced into pUC18 containing a following linker sequence: { SphI) -CATCCGGAGGCGGTGGCTCGGGCGGTGGCGGCTCGGGTGGCTCTGC- ( Ncol) . This plasmid was digested by Ndel and Ncol, and introduced into pET20b containing V L DNA. Then, this plasmid was digested by Xho I and a following sequence that codes flag sequence was introduced, TCGATTACAAGGACGACGATGACAAGC The resulting plasmid was transformed into BL21(DE3) pLysS Cells were grown in LB medium at 37°C At an OD 550 of 0 6 IPTG was added to a final concentration of 2mM, and the cells were further grown for 2 hrs. before harvest. The cells were suspended m 20 of culture volume of binding buffer (5mM ιmιdazole/0.5M NaCl/20mM Tris-HCl, pH 7.9) /6M Urea, disrupted by freezing and thawing and removed debris by centrifugation (lOOOOg x 20 mm) Supernatant was applied to HistBmd Resm Column (Novagen) and eluted with 6M urea/lM ιmιdazole/0.5M NaCl/20mM Tris-HCl pH 7.9 Elisa analysis of the resulting single chain Fv fragment demonstrated binding activity Enzymatic activity was confirmed by the release of the H benzoic acid from the J H phenyl-cocaine. EXPERIMENTAL DISCUSSION The clinical application of a catalytic antibody against cocaine relies on a kinetic argument since a 100 mg dose of cocaine if antagonized solely by antibody binding would require 25 g of antibody (assuming an antibody MW of 150 kD and 2:1 cocaine :antibody stoichiometry) . Active immunization with cocaine tethered to an immunoconjugate would be unlikely to provide more than a few percent of this requirement (25) . Polyclonal gamma globulin can be administered m doses of this magnitude but clearly only enzymatic turnover reduces the antibody requirement to a practical magnitude and, most importantly, allows for the burden of repetitive self- admmistration - the hallmark of addiction The optimization of an anti-cocame catalytic antibody which greatly reduces the cost per dose can be approached through improved analog design, large scale antibody selection (26) and antibody mutagenesis (27) . Mab 15A10 and 8G4G are the preferred candidates for optimization since they are the most active catalytic antibodies, they are structurally distinct (see below) , and Mab 15A10, and possibly 8G4G, could already manifest some element of chemical catalysis. The failure of decades of effort to identify classical receptor blockerε of cocaine, together with the compelling nature of the cocaine problem, justify an exhaustive strategy employing all three approaches. One impediment to this effort is the limited diversity of the antibodies elicited by a given analog Clearly, antibody diversity is not necessary if, by chance, a single class of antibodies ultimately yields a member with the desired kinetic parameters. However, the capacity of a given antibody to be optimized to specification cannot be predicted due to the scarcity of structural data on catalytic antibodies. The generation of a diverse group of anti-cocame catalytic antibodies should improve the prospects for successful optimization whether through repetitive large-scale hydπdoma preparation or through mutagenesis Using the tetrazole catalysis method for phosphonate ester synthesis, three transition-state analogs of cocaine hydrolysis were synthesized. The core phosphonate monoester structure was identical in each and only the tether sites varied. All three elicited catalytic antibodies and a competitive ELISA and CDR sequencing were used to define functional and structural groupingε, respectively. A comparison of the CDR's of the active antibodies delineated four discrete non-overlapping families that were elicited specifically by TSA 1 (3B9-6A12-2A10 and 9A3-19G8-15A10) and TSA 2 (8G4G and 8G4E) . TSA 2 yielded one antibody highly homologous to the 3B9-6A12-2A10 family from TSA 1 and without homology to the antibodies derived from TSA 2- These structural families overlapped in part with two broad groups defined by a CIEIA method in which amides 8_, 12, and 18 (representing TSA 1, 2 and 2, respectively) inhibited the binding of each catalytic antibody to its eliciting TSA. One group defined by CIEIA conεiεted of Mab's 3B9, 6A12, 2A10 and 12H1. This group displayed high affinity for 8_, moderate affinity for 12 and very low affinity for 18. All of the highly homologous members of this group could have been elicited by TSA 1; the one antibody derived from TSA 2 , Mab 12H1, bound TSAl-related amide 8 . with even greater affinity than TSA2-related amide 13. Nonetheless it is possible that most if not all of the group could have been elicited by TSA 2 . since the range of affinities for 12 in this group overlapped with the range of affinities for the amides of the TSA' s that elicited each antibody. In contrast, the very low affinity of 18 for every member of this group suggests that TSA 2 could not yield any member of the group. A strategy to obtain catalytic antibodies against cocaine based only on a TSA tethered at the tropane nitrogen (28) would fail to identify this group of antibodies. The second group defined by CIEIA consisted of five catalytic antibodies from three structural families: 9A3- 19G8-15A10 derived from TSA 1; 8G4G and 8G4E from TSA 2- These five antibodies displayed equally high affinity for amides 8 and 18 . and in principle either TSA 1 or 2 could have elicited every catalytic antibody in this group. That TSA l and 2 did not yield members of a common structural family may reflect the inadequacy of a sample size averaging 3 fusions per analog. None of the five antibodies could have been obtained with TSA 2 . and thus three of the four structural families would not have been identified with this conjugate. TSA 1 elicited the most active catalytic antibody, Mab 15A10. Moreover, based on the high affinity of amide 8_ for all nine catalytic antibodies, TSA 1 could plausibly have elicited every antibody described. This result was unexpected but not a definitive endorsement of TSA 1 as the preferred analog. With more aggressive screening, TSA 2 . or 2 m ay ultimately yield a more active antibody not recognized by TSA 1. Clearly, the failure of a TSA (e.g. TSA 2 . ) to bind to a catalytic antibody (e.g. 15A10) derived from an alternate immunogenic conjugate confirms that the location of the tether limits the catalytic antibodies produced and supports varying the site of attachment to carrier protein. Exhaustive screening of hybridomas from TSA 1, 2 and 2 a πd detailed structural studies of the catalytic antibodies elicited may clarify the rules for analog construction. The pursuit of high activity anti-cocaine catalytic antibodies provides a compelling justification for this effort. REFERENCES FOR THE FIRST SERIES OF EXPERIMENTS 1. Goeders, N. E.; Smith J. E.

SECOND SERIES OF EXPERIMENTS Introduction Cocaine overdose, a potentially fatal syndrome, has long defied development of antagonists. To provide a new approach, a high activity catalytic antibody was elicited using a transition-state analog for the hydrolysis of cocaine to non-toxic products. This antibody protected rats from cocaine-induced seizures and sudden death in a dose-dependent fashion. Consistent with accelerated catalysis, the hydrolysis product ecgonine methyl ester was increased > 10-fold in plasma; a non-catalytic anti- cocaine antibody did not reduce toxicity. This artificial cocaine esterase is the first rationally designed cocaine antagonist and the first catalytic antibody with potential for medicinal use. Cocaine is presently abused in the United States by approximately two million hardcore addicts and over four million regular users (1) . The acute toxicity of cocaine overdose frequently complicates abuse and the potential medical consequences of this syndrome include convulsions ■ and death (2) . Despite decades of effort, however, no useful antagonists to cocaine have been found. This failure is due, in part, to the drug's unique mechanism of action as a competitive blocker of neurotransmitter re-uptake (3) . Thus, cocaine's blockade of a dopamine re-uptake transporter in the central nervous system (CNS) is hypothesized to cause reinforcement (4) and the difficulties inherent in blocking a blocker appear to have hindered the development of antagonists for addiction. For cocaine overdose this problem is compounded by the binding of cocaine at high concentrations to multiple receptors in the CNS and cardiovascular systems. For instance, blockade of serotonin-reuptake transporters contributes to cocaine- mduced convulsions (5,6) ; dopamine-reuptake blockade (6) and dopamine D x receptor binding (7) contribute to lethality; and blockade of norepmephrme-reuptake transporters, as well as blockade of cardiac myocyte Na 4 channels and other ion transporters, contributes to arrhythmias and sudden death (8) . Thus, cocaine overdose may well pose an insurmountable problem for the classical receptor-antagonist approach These difficulties in developing antagonists for cocaine abuse led to a new approach - to intercept cocaine with a circulating agent thereby rendering it unavailable for receptor binding An antibody is an obvious choice for a circulating interceptor but, as noted m the original 1974 report on anti-heroin antibodies, the stoichiometric binding of the drug effectively depletes antibody (9) To overcome the limitations of binding, catalytic antibodies were developed - a novel class of artificial enzyme (10) - with the capacity to bind and degrade cocaine, release product and become available for further binding (11) . Since degradation of cocaine at its benzoyl ester yields non-toxic products, ecgonine methyl ester (12) and benzoic acid (13) (Figure 28A) , a phosphonate monoester transition-state analog for oenzoyl ester hydrolysis (TSA-I, Figure 28B) , was synthesized and with it elicited the first catalytic antibodies to degrade cocaine in vitro (11) . The catalytic activity of these antibodies was insufficient to demonstrate a biologic effect but through repetitive hybridoma preparation with the reagent TSA-I, Mab 15A10, an antibody 100-fold more potent at sub- saturating concentrations of cocaine (14) was generated This antibody is the most potent artificial cocaine esterase to date with a Michaelis constant of 220 μM, a turnover rate of 2.3 mm 1 , and a rate acceleration of 2.3 x 10". The antibody retained >95% of its activity after >200 turnovers and product inhibition, a frequent impediment to useful antibody catalysis (15) , was not observed for the alcohol product ecgonine methyl ester at concentrations up to 1 mM Although Mab 15A10 was inhibited m vitro by benzoic acid (Kd ~ 250 μM) , this acid is rapidly cleared from plasma through coupling to glycine (13,16) and the adduct, hippuric acid, was not an inhibitor m vitro at a concentration of 1 mM. Thus, Mab 15A10 possesses several characteristics essential for a practical m vivo catalyst Using Mab 15A10, the antibody-catalyzed degradation of cocaine was tested to see if it could block the acute toxicity of cocaine overdose in rat . The toxicity of cocaine can vary significantly among individuals depending on endogenous catecholamme levels and this likely explains the variably increased incidence of sudden death in restrained animals (17) and agitated patients (18) . In previouε work (19) , catecholamme levels were standardized through intravenous infusion in conscious, unrestrained animals and, for continuously infused cocaine (1 mg/kg/min) , found that the LD 5( was 10 mg/kg and the LD 9( was 16 mg/kg. Using this method (20) , animals pretreated with Mab 15A10 (21) showed a significant (p<0.001) dose-dependent increase m survival to an LD q0 cocaine infusion (Figure 29) Four of five animals receivmg antibody at 15 mg/kg and all of five receiving antibody at 50 mg/kg survived. In contrast, all eight rats not treated with Mab 15A10 expired before the cocaine infusion was complete. In the animals not treated with Mab 15A10, the mean cocaine dose at death was 7.5±0.6 mg/kg, whereas the five treated with antibody at 5 mg/kg expired at a mean cocaine dose of 8.2+ . 1.0 mg/kg and the single non-survivor in the group treated with antibody at 15 mg/kg expired at 15.9 mg/kg of cocaine . To further quantify the protective effect of the catalytic antibody, the 15A10 (100 mg/kg) and control groups were overwhelmed with intravenous cocaine continuously administered at 1 mg/kg/min until all animals expired (Figures 30A and 30B) . The dose of cocaine at seizure averaged 9.48 mg/kg for saline controls and 32.5 mg/kg for animals treated with Mab 15A10 (p<0.01) (Figure 30A) . The mean lethal dose of cocaine was also increased over 3-fold, from 11.5 mg/kg of cocaine for controls to 37.0 mg/kg for the Mab 15A10 group (p<0.01) (Figure 30B) . Simple binding was an unlikely explanation for the effectiveness of Mab 15A10 since stoichiometric binding of cocaine would be expected to shift the dose-response to cocaine by < 1 mg/kg. However, to exclude this possibility, the action of a binding antibody, Mab ICl, was tested at an equal dose . Mab ICl was elicited by immunization with TSA-I, but the antibody is not catalytically active since it binds free TSA and cocaine with comparable affinity (22) . As expected, Mab ICl was ineffective in blocking cocaine-induced convulsions or death (Figures 30A and 30B) . To demonstrate in vivo catalysis, the plasma concentrations of cocaine hydrolysis products in the 15A10 and control groups were measured by previously developed high-pressure liquid chromatography (HPLC) method (23) . The 15A10 group showed a >10-fold increase in ecgonine methyl ester (24) compared to either the saline (p<0.001) or the Mab ICl (p<0.01) control groups (Figure 30C) . As expected based on its rapid metabolism (13,16), plasma benzoic acid concentrations were not significantly elevated in the 15A10 group (3.85±0.89 μM) compared to the saline control group (2.36±1.05 μM) . Consistent with specific catalysis at the benzoyl ester, the plasma concentration of the methyl ester hydrolysis product, benzoyl ecgonine (Figure 28A) , was not significantly increased in the Mab 15A10 group (7.68 . + 1.07 mM) compared to saline control (5.47+ . 1.01 μM) . Plasma cocaine concentrations in 15A10 and control groups were measured at death by HPLC (23) in order to confirm that Mab 15A10 conferred resistance to cocaine toxicity through a pre-receptor mechanism. A marked elevation of plasma cocaine would be expected if Mab 15A10 acted at or after the binding of cocaine to its receptors. In contrast, plasma cocaine concentrations at death were not significantly different between 15A10 and control groups (Figure 30D) , as expected for a pre-receptor effect and consistent with protection from toxicity through catalyzed degradation of cocaine. The present study provides a proof of the concept for the use of circulating catalytic antibodies to block the toxic effects of cocaine. The incidence of cocaine overdose in the United States is approximately 80,000 cases per year and cocaine-related deaths exceed 3,000 per year (1) . An anti-cocaine catalytic antibody could be a useful therapeutic for patients manifesting serious complications of overdose such as seizures and arrhythmias. Mouse monoclonal 15A10, the first catalytic antibody with potential for medicinal use, is a suitable candidate for mutagenesis to further improve kinetics (25) and protein engineering to enhance human compatibility (26) . Assessment of Mab 15A10 and more active homologs in an animal model based on antibody post-treatment αf cocaine toxicity would precede human trials. Since the original report on anti-cocaine catalytic antibodies (3), others have described variations on the concept of intercepting cocaine before the drug reaches its receptors. For example, intraperitoneal administration of the enzyme butyrylcholinesterase was shown to inhibit toxicity due to intraperitoneal cocaine in mouse (27) . Also, non-catalytic anti-cocaine antibodies were shown to diminish cocaine-induced psychomotor effects and reinforcement in rat (28) . However, catalytic antibodies are likely to be longer- lived in plasma than natural enzymes and, in contrast to typical antibodies, not susceptible to depletion by complex formation with cocaine. Thus, catalytic antibodies have the unique potential to treat both the acute and chronic aspects of cocaine abuse and, as a result, practical experience with acute overdose can provide a foundation for the treatment of chronic addiction.

Male rats (350-400g) were fitted with femoral arterial and venous catheters under pentobarbital anesthesia. After 24 hrs arterial pressure was transduced and catecholammes [norepinephrine (0.725 μg/min) , epinephrine (0.44 μg/min) , and dopamine (0.8 μg/min)] were infused intravenously with co- infusion of cocaine at one mg/kg/min for 16-min. HPLC measurements of catecholamines levels (9) at baseline and at the time of cardiopulmonary arrest were found not to be significantly different between groups (p>0.05) . 21. Hybridoma 15A10 was seeded in a Fibra Cel cell support matrix (Cellagen Plus bioreactor, New Brunswick Scientific Co, New Brunswick, NJ) continuously perfused with RPMI 1640 (GIBCO) medium. Perfusate was concentrated with a prep, scale 10K 6 sq. ft. cartridge (Millipore) and subjected to Protein G chromatography to yield Mab 15A10 >90% pure by SDS-PAGE chromatography. Catalytic activity was comparable to that previously described 1'1 and was completely inhibited by free TSA (50 μM) . Endotoxin levels were < 0. lEU/ml by QCL - 1000 quantatitive chromogenic LAL assay. 22. Mab ICl was obtained from the original hybridoma preparation with TSA-I as described(14) .
