METHOD OF TREATING GLIOMA CANCER USING TARP GAMMA 8-DEPENDENT AMPA RECEPTOR ANTAGONISTS FIELD OF THE INVENTION id="p-1" id="p-1" id="p-1" id="p-1" id="p-1" id="p-1"
[0001] The embodiment ofs the present invention relat toe methods for treating a malignant glioma comprising administering a therapeutically-ef amoufectintve of a TARP yS-dependent AMPA receptor antagonist.
BACKGROUND OF THE INVENTION id="p-2" id="p-2" id="p-2" id="p-2" id="p-2" id="p-2"
[0002] Glial-derived tumors (/.e., gliomas) are a common type of tumo orir ginati inng the brain rath erthan a metastati brainc cancer. Abou t33% of all brain tumors are gliomas, which originate in the glial cell thats surround and suppo rtneurons in the brain includi, ngastrocytes, oligodendrocytes and ependymal cells Gli. omas are transformed cells that display increased metabol activitic asy a result of the transformatio process.n Neoplasti transformatic canon occur in all glia celll types, there byproducin a glarg rangee of patholog icaland morphological variants.
Most primary brain tumors derive fromd glia cellsl have lost growt controh regulal tion, giving rise to astrocytomas, glioblastomas, or oligodendrocyt omas.In the 2016 Worl dHealt hclassificat ion of brain tumors, there were no less than 36 different subtypes of glioma identified based, on histology and variou biomars kers.1 id="p-3" id="p-3" id="p-3" id="p-3" id="p-3" id="p-3"
[0003] Glioblastoma multifor (GBM)me , also known as glioblastoma, recurr entGMB, and/ograder IV astrocytoma, is an extremely aggressive tumo r.Symptoms are simila tor those of othe brainr tumors, and may include seizure, nausea and vomiting, headache, memory loss, hemiparesis, and progress memory,ive personality, or neurological defici duet to tempor aland fron tallobe involvemen Althot. ugh any brain tumo canr cause seizures, thei developmentr is most commonly associate withd neuroepithe tumorlial s,includi ngGBM. The incidence of epilepsy in patien tswith GBM varies betwee 30%n and 62%, in about two thirds as present ing symptom and in one third developing during the course of the disease.2 id="p-4" id="p-4" id="p-4" id="p-4" id="p-4" id="p-4"
[0004] It is very difficult to treat glioblastoma dues to several complicati factors.ng GBM tumo cellsr are generally very resistant to conventional therapies. These tumors conta inmany different type sof cells, where insome cells may respond well to certa thein rapies, whil eothers may not be affecte atd all .Another complicat ingfact oris that normal brai ncells are relativ ely susceptib tole damage due to conventional therapy, and the brain has a very limite dcapacity to repair itsel comparedf to other organs. The fact that many drugs cannot cross the blood-brain 1 barrier to act on the tumo furtherr limit sthe range of chemotherapie suits able for treating GBM patients. id="p-5" id="p-5" id="p-5" id="p-5" id="p-5" id="p-5"
[0005] GBM has the worst prognosi ofs any central nervous system (CNS) malignancy, despite multimodal treatity ment consisti ngof surgical resecti onof as much of the tumo asr possible, with concomitan or tsequential chemothera radiothpy, erapy, antiangiogenic therapy, immune therapy, gamma knife radiosurge andry, symptomat managemic ent wit h corticostero Prognoids. sisis very poor, with a median survival time of approximat oneely year and the disease is almost invariably fatal, as only about 3% survive for more than 3 years. id="p-6" id="p-6" id="p-6" id="p-6" id="p-6" id="p-6"
[0006] Accordingly, there is a need for new therapeu targtic ets and improved modaliti es for the treatmen of tmalignant gliomas, including GBM.

There are several main type sof cancer Carci. noma is a cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is a cance thatr begin sin bone, cartilage, fat, muscle, bloo dvessels, or other connect iveor support ivetissu e.Leukemia is a cancer that start ins blood-formi tingssue such as the bone marrow, and causes larg numberse of abnormal bloo dcells to be produced and enter the blood. Lymphoma and multipl myelomae are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissue ofs the brain and spinal cord. id="p-37" id="p-37" id="p-37" id="p-37" id="p-37" id="p-37"
[0037] In some embodiment ofs any of the aspects, the cance isr a primary cancer. In some embodiment ofs any of the aspect s,the cance isr a malignant cancer.

Glutamate Receptors id="p-82" id="p-82" id="p-82" id="p-82" id="p-82" id="p-82"
[0082] Glutamate is the primar excity ator neurotransmity in mammaliter an brain.
Glutamatergi signalic ngparticipa tesin a wide range of neural functions includi nglearning and memory, long-te rmpotentiat andion synaptic plasticity. Glutamate receptors can be divided into two families The. ionotropic glutama receptorste form ion channels that activate upon binding agonist opening, a pore through the plasma membrane through which cations can flow. The metabotropic glutamate receptor ares G-protein-coup receptorled actis, vati ngintracellular signal transduct cascades.ion The ionotropic glutamate receptor cans be further subdivided into fou r sub-familie baseds, upon sequence homolo gyand selectivi toty exogenou agons ists. These sub-families are the AMPA a-amino-3-hydroxyl-5-methyl-4-isoxazole- acid),prop NMDionAic (N-methyl-D-aspart ate),kainate, and delta receptors. id="p-83" id="p-83" id="p-83" id="p-83" id="p-83" id="p-83"
[0083] The AMPA subtype of glutamat recepe tor ares glutama sensitite ve ion channels on postsynaptic membranes of excitatory synapses in the central nervous system (CNS) and are largely responsib forle mediatin fastg neurotransmissi acrosson synapt icgaps. AMPA receptor assembls ase tetramers of subunits. Mammals express four AMPA-receptor subunits, calle Glud A1-GluA 4.Each GluA subun itcan be expressed in multipl splicee variants; the two most prominent splice varian tsare called flop and flip .GluA subunits freel formy functional homo- and hetero-tetramers. The majorit ofy RNA encoding GluA2 subunits is edited post- transcription alterially, nga genetically-encoded glutamine to arginine. This RNA editing causes AMPA receptor to spreferenti formally wit htwo GluA2 units, and also prevents calciu mentr y through the activat edreceptor. id="p-84" id="p-84" id="p-84" id="p-84" id="p-84" id="p-84"
[0084] In thei natir ve environment, the pore-forming GluA tetrame direcrs tly or indirectl y associat withe numero usauxiliary protei nswhich modify the trafficking, localization, gating characteristics, and pharmacology of the AMPA recept (AMPAR)or . These auxiliary subunit s include cytoskelet andal anchori ngproteins, other signaling proteins, and several intracellul ar and transmembrane proteins with unknow functn ion. The wide variet ofy protei nswhich can participate in AMPA recept complexesor vastly increases the ability of a neuron to tune the response characteristi of itscs synapses. id="p-85" id="p-85" id="p-85" id="p-85" id="p-85" id="p-85"
[0085] Transmembrane AMPA Recept orRegulatory Proteins (TARPs) are a fairly recen tlydiscovered family of proteins that have been found to associate wit hand modula tethe activi tyof AMPA receptor Severals. TARPs are fairly regiospecifi in thec brain, leading to physiolog icaldifferentiatio of then AMPA recept activior ty. For example, TARP y2 (stargazi n) dependent AMPA receptor ares primar illocaly ized in the cerebellum and cerebral corte andx TARP y8 dependen AMPAt receptor ares localized primari inly the hippocampus, which region is 21 particularly relevant to seizure originati and/oon propagatr ion.It has been theorized that target ingindividu alTARPs may enable selective modulation of specifi brainc circu itswithout globa llyaffecti synaptng ictransmissio16 n.

[0086] AMPA recept antagonistsor are known anticonvulsant agents and thei abir lity to down modula teexcitator neuroty ransmissio is keyn to thei antir -epilepti therapc euti potc ential.
However, since AMPA recept activior tyis so ubiquito usin the CNS, general antagoni smaffec ts most areas of the CNS resulting in undesir edeffects, such as ataxia, sedation, and/or dizziness, which are shared by all known general AMPA receptor antagonists Typical. ly, these general antagonist haves very narrow therapeuti dosinc gwindows, meaning that typically the doses neede dto obtain anti-convulsant activit arey close to or overl apwith doses at which undesired effects are observed.17 id="p-87" id="p-87" id="p-87" id="p-87" id="p-87" id="p-87"

[0089] Several selectiv none, -competitive TARP y8-dependent AMPA recept or antagonist weres subsequently developed to be effective anti-seizure/anti-epile therapeuticptic drugs without the side effects (e.g., sedation, ataxia, and/o dizzinr ess) of general (non-TARP dependent/non-selecti AMPAve) antagonists or TARP y2-dependent AMPA antagonists. Some selective, non-competi tiveTARP y8-dependent AMPA receptor antagonists are described in, for example, U.S. Patent Nos. 8,765,960 and 9,469,632. id="p-90" id="p-90" id="p-90" id="p-90" id="p-90" id="p-90"
[0090] AMPA recept antagonistsor are known anticonvulsant agents, and thei abilir ty to down-modulate excitatory neurotransmission is critical to thei antiepilr eptic therapeuti potentic al.
However, because AMPA recept activor ity is so ubiquito usin the central nervous system (CNS), a non-select AMPAive recept antaor goni approachst affects many areas of the CNS, resulting in undesired effects such as ataxia, sedation fal, ls, and/or dizziness, which are share dby all 22 known general or broad-spectrum AMPA recept antagonior sts. Typically, the doses of these medications needed to obtain anticonvuls activiant tyare close to, or overl apwith, doses at which undesired effects are observed. id="p-91" id="p-91" id="p-91" id="p-91" id="p-91" id="p-91"
[0091] TARPs are a fair lyrecentl discovey red family of proteins that have been foun dto associat withe and modulat thee activit ofy AMPA receptor TARP-s. y8-depende ntAMPA receptor ares localized primari inly the hippocampus a ,region of importance in complex partial seizures and particul arlrelevany tot seizur origie natio and/on propagation.r Research suggest s that selectively targeting individual TARPs may enable selecti vemodulation of specifi braic n circui witts hout global affly ecti ngsynaptic transmissio resuln, ting in improved efficacy, safety, and tolerability. id="p-92" id="p-92" id="p-92" id="p-92" id="p-92" id="p-92"
[0092] ES-481 (previousl knowny as CERC-611, LY3130481, LSN3130481,3130481) was discovered with the goal of retaini ngefficacy in epilept patientsic but avoiding the motori c adverse event (AEs)s that are a known liabili tyof global AMPA recept antaor gonists.
Important ES-481ly, is the first molecul knowne to selectively target and functional blockly region-spec AMPAific receptors after oral dosing. This selectivity was engineered into ES-481 by chemical structure-activit relatiyonshi (SAR)p studies to achieve selecti veblockade of AMPA receptor associates withd the auxiliary protei TARP-y8n (high densit iny hippocampus, a regio n of importance in partial epilepsies) whil esparin AMPAg receptor assocs iate witd hTARP-y2 (high density in cerebellum, which regulates the ataxi aand falli ngassociate witd hFycompa® (perampanel)). id="p-93" id="p-93" id="p-93" id="p-93" id="p-93" id="p-93"

Gliomas id="p-94" id="p-94" id="p-94" id="p-94" id="p-94" id="p-94"
[0094] Glial-derived tumors (/.e., gliomas) are a common type of tumo orir ginati inng the brain rath erthan a metastatic brain cancer. Abou t33% of all brain tumors are gliomas, which originate in the glial cell thats surround and suppo rtneurons in the brain, includi ngastrocytes, oligodendrocy andtes ependymal cells Gli. omas are transformed cells that display increas ed metabol activiic tyas a result of the transformat process.ion They comprise a diverse grou ofp neoplasms that diff erin thei morphology,r thei CNSr location, thei degr ree of invasiveness, their tenden cyfor progressio andn, thei growthr characteristi Neoplastcs. transfic ormatio can occurn in all glia celll types, thereby producin a glarg rangee of patholog icaland morphological variant s.
Most primary brain tumors derive fromd glial cell haves lost growt controh regulal tion, giving rise 23 to astrocytomas, glioblastomas, or oligodendrocytoma In thes. 2016 Worl dHealt hclassificat ion of brain tumors the, re were no less than 36 different subtypes of glioma identified based, on histology and various biomarkers.18 id="p-95" id="p-95" id="p-95" id="p-95" id="p-95" id="p-95"
[0095] Astrocytomas are glial cell tumors develope fromd connect ivetissue cells called astrocytes and are the most common primar intra-axialy brain tumo r,accountin forg nearl halfy of all primary brain tumors They. are most often foun din the cerebrum (the large, outer part of the brain) but, also in the cerebellum (locat edat the base of the brain). id="p-96" id="p-96" id="p-96" id="p-96" id="p-96" id="p-96"
[0096] Astrocytomas can develop in adult ors in children. High-grade astrocytomas, calle gliobd lasto mulma tiforme (GBM), are the most malignant of all brain tumors Gl. ioblastoma symptom ares often the same as those of other gliomas. Pilocytic astrocytomas are low-grade cerebell umgliomas commonl founy din children. In adults, astrocytomas are more common in the cerebrum. id="p-97" id="p-97" id="p-97" id="p-97" id="p-97" id="p-97"
[0097] Brain stem gliomas, also called diffuse infiltrati brainng stem gliomas or diffuse intrinsic pontin glie omas (DIPGs), are rare tumors found in the brain stem. They usually canno t be surgical removely becaused of thei remoter location, where they intertw inewit hnormal brai n tissue and affect the delicate and complex functio thins sarea controls. These tumors occur most often in school-age children where they are responsib forle the greatest number of childhood deaths from primary brain tumors. id="p-98" id="p-98" id="p-98" id="p-98" id="p-98" id="p-98"
[0098] Ependymomas develop from ependymal cells lining of the ventricles or in the spina cord.l Ependymomas are rare, accountin forg just 2% to 3% of primary brain tumors.
However, they account for about 8% to 10% of brain tumors in children and are more likely to affe ctthose younge thanr 10 years old. The most locati onfor ependymomas in children is near the cerebellum, where the tumo canr block the flow of the cerebral spina fluil dand cause increased pressure inside the skull (obstructive hydrocephal us).These tumors can sprea dto other parts of the brain or spina lcord (drop-metastases) due to the flo wof spina fluil d. id="p-99" id="p-99" id="p-99" id="p-99" id="p-99" id="p-99"
[0099] Mixed gliomas (also called oligo-astrocytomas) are made up of more than one type of glial cell Thei. r diagnosis as a distinct tumo typer is controversi andal may be resolved with genetic screening of tumo tisr sue. These tumors are often found in the cerebrum and are most common in adul men.t id="p-100" id="p-100" id="p-100" id="p-100" id="p-100" id="p-100"
[0100] Oligodendrogliomas form from oliogodendrocytes, the support ivetissue cell ofs the brain and are usually foun din the cerebrum. Abou t2% to 4% of primary brain tumors are oliogodendroglioma Theys. are most common in young and middle-ag edadults and more likely to occur in men. Seizures are a very common symptom of these gliomas (affecti 50%ng to 80% of patients) as, well as headache, weakness, or problems wit hspeech. Oligodendrogli omas 24 typically have a bette prognosisr than most other gliomas. They are significant morely favorable in term sof their biological behavior and thei prognosisr for patien tsand can have survivorshi p measured of decades for folks with these tumors that have the most favorabl biomarkere profiles. id="p-101" id="p-101" id="p-101" id="p-101" id="p-101" id="p-101"
[0101] Optic pathway gliomas are a type of low-grade tumo foundr in the optic nerve or chiasm. They often infiltrate the opti cnerves, which send messages from the eyes to the brain.
Peopl ewith neurofibromat areosis more likely to develop them. Optic nerve gliomas can cause vision loss and hormone problems, since these tumors are often locate atd the base of the brai n where hormonal contr isol located. Gliomas affecti nghormone functio mayn be known as hypothalamic gliomas. id="p-102" id="p-102" id="p-102" id="p-102" id="p-102" id="p-102"
[0102] The most importan determit nant of survival for gliomas is the "grade" of the glioma. Increasing grades represent increasing malignancy and decreasing differentiati on, which is associate witd hincreased mitoti activic tyand enhanced cell migration.19■20 Grade I tumors grow slowl andy can sometimes be totall removey byd surgery, while grad eIV tumors are fast-grow aggressiing, ve,and difficu tolt trea t.High-grade gliomas account for 30% of primary brain tumors in adults and are the second most common cause of cancer death in children under 15 years of age. High-grade gliomas are divided by grad einto two categori es: anaplast astrocic ytomas (WHO Grade III) and glioblasto mulma tiforme (GBM; WHO Grade IV).21 id="p-103" id="p-103" id="p-103" id="p-103" id="p-103" id="p-103"
[0103] GBM (Grade IV) tumors are characterize by thed presence of areas of necrotizi tissung thate are surround byed anaplast celic ls with numerous mitosi sand endotheli al proliferat Thision. characterist as ic,wel asl the presence of hyperplastic abnorma bloodl vessels, differenti atesthe tumo fromr Grade III astrocytoma whichs, do not have these features.
GBM tumors usually appea rin the cerebral whit ematter, grow quickly, and can become very larg befe ore causing symptoms. Less than 10% form more slowly, following dedifferentiation of low-grade astrocytoma or anaplast astrocytic oma. These are called secondary GBM tumors and are more common in younger patient (means age 45 versus 62 years). The tumo mayr extend into the meninges or ventricular wall, leading to high protei conten ntin the cerebrospin al flui d(CSF) (>100 mg/dL), as well as an occasional pleocytosis of 10 to 100 cells, mostly lymphocytes. Malignant cells carri edin the CSF may spread (rarely) to the spina lcord or cause meningeal gliomatosis. However, metastasi ofs GBM beyon dthe central nervous system is extremely unusual. Abou t50% of GBM tumors occupy more than one lobe of a hemisphere or are bilatera Tumorsl. of this type usually aris efrom the cerebrum and may rarel exhibity the classic infiltrati acrosson the corpus callosum, producing a butterf (billyateral gliom) a. id="p-104" id="p-104" id="p-104" id="p-104" id="p-104" id="p-104"
[0104] GBM has the worst prognosi ofs any central nervous system (CNS) malignancy, despite multimodal treatity ment consisti ngof surgical resecti onof as much of the tumo asr possible, with concomitan or tsequential chemothera radiothpy, erapy, antiangiogenic therapy, immune therapy, gamma knife radiosurge andry, symptomat managemic ent wit h corticosteroids. Progno sisis very poor, with a median survival time of approximatel oney year and the disease is almost invariably fatal, as only about 3% survive for more than 3 years.

[0107] Research has recently start edto focu ons these pathophysiologi mechanismscal and on the possibiliti fores new mechanism-based anti-epilept treaic tmen ts.Two recen t investigations assessed the effects of perampanel (FYCOMPA®), the first antiepilep drugtic in the class of selecti venon-competiti antave goni ofst AMPA receptors,27 on glioma. Izumot oet al. (2019)28 assessed the effects of perampanel on the response to seizure and tumo­r progression in 13 patients wit hgliomas and uncontrollabl seizures.e Perampanel (4 mg/da yor 8 mg/day) was tested after surgery, radiation, and chemotherapy treatment Epils. epti seizuresc were reporte tod be eliminat edin eight of the 13 patients and volume reduction was detected during the 6 month period. Unfortunat theely, abstract does not specify if the radiatio andn chemotherapy overlapped wit hthe perampanel treatment. The authors concluded that perampanel treatment was effective at control litheng epilepsy and inhibiting tumor progression.
However, the abstract does not discuss the potentia contrl ibu tieffectsng of surgery, radiation, and chemotherapy treatment to sthe observed beneficial effects attributed to perampanel In. contrast to the alleg edbeneficial effects reported by Izumoto etal. (2019), a subsequent report by Mayer etal. (2020)29 indicate thatd perampanel inhibited epileptifor dischargesm in 26 organotypic brain slice ofs glioma but failed to attenuat tumoe growtr orh promote animal survival in rat C6 glioma model. id="p-108" id="p-108" id="p-108" id="p-108" id="p-108" id="p-108"
[0108] Even if perampanel was determined to be effective at attenuati tumorng growth and/o promr otin theg survival of subjects afflict withed a glioma, it shoul bed noted that this drug has significan advert se effects. The drug label has an FDA box warning that the drug cause may cause serious psychiat ricand behavioral changes; it may cause homicidal or suicidal thoughts.30 Other side effects have included dizziness, somnolence, vertigo, aggression, anger, loss of coordinat ionblur, red vision, irritabi litandy, slurred speech. Perampanel also reduces the effectivenes of levos norge streoral contraceptivesl by about 40%.31 Women who may get pregna ntshould not take it as studies in animals show it may harm a fetu s.Perampanel is liable to be abused; very high doses produced euphoria responses simila tor ketamine.

[0109] Severe brain cance rshave been shown that integrat intoe the brain’s wiring.33■34 High-grade gliomas, includi ngglioblastoma, form synapses that hijack electr icalsignal froms healthy nerve cells to drive thei ownr growth. High-grade gliomas form synapses with healthy neurons that transmit electri calsignal tos the cancerous tissu e.The tumors also contai cell-to-n cell electri calconnections known as gap junctions. Togethe ther, two types of connections allow electrical signals from healthy nerve cells to be conducted into and amplified within the tumors. id="p-110" id="p-110" id="p-110" id="p-110" id="p-110" id="p-110"
[0110] High-grade gliomas include glioblastoma, a brain tumo seenr in adults that has a five-yea survivalr rate of 5%; diffuse intrinsi ponc tin glioe ma, a pediatric brain tumo withr a five- year survival rate belo w1%; and other diagnos essuch as pediatri glic oblastoma and diffus e midline gliomas occurring in the spina lcord and thalamus.

[0111] Existing drugs that block electr icalcurrent haves been foun dto reduce growt ofh high-gra degliomas. Perampanel, a seizur medicae tion that blocks activity of neurotransmit ter receptor on sthe receiving end of a synapse, was reported to reduce proliferation of pediatri c gliomas implant edinto mice by 50%.

[0112] AMP-type glutamat recepte ors (AMPARs) are the principa transl duce ofrs fast synapt ictransmission in the mammalian CNS. When high-grade gliomas form synapses with 27 healthy neurons that transmit electr icalsignal tos the cancero tissues,us these connections allow electrical signals from healthy nerves to be conducted and amplified within the tumor; allowing tumo growth.r It was thus hypothesized that the use of selective TARP y8-dependent AMPA recept antagonor ists has the potent ialfor anti-tumorigenic effe ctby slowing down or inhibiting these electri calconnections. id="p-113" id="p-113" id="p-113" id="p-113" id="p-113" id="p-113"

[0135] Cisplati wasn employed as a positive control for thi sstudy. Cisplatin is one of the most effective chemotherapeutic agents to date used for the treatment of many malignancies, includi ngglioma.43 Cisplati causesn tumor cell death by direct DNA damage and by generat ing 34 reactive oxygen intermediates. Cisplat inis the most common platinum chemotherapy drug; it was first approved in the U.S. in 1978. But cisplatin is not without its problem s.It has an extensive list of horrible side effects including severe nausea and vomitin g.These two side effects are, in fact so, bad that the drug's development was almost stopped when it was first tested on peopl e.In addition, tumors can become resistant to platinum-based chemotherapy drugs. id="p-136" id="p-136" id="p-136" id="p-136" id="p-136" id="p-136"

[0145] Female Mus musculus BALB/c nude mice (n=30) were obtained from Beijing Anikeeper Biotech Co., Ltd (Beijing, China). At the initiation of the study, mice were 7-8 weeks old (estimat edage at inoculati on)wit ha body weigh oft 17.0-21.9 g. Mice were housed in Polysulfon IVCe cage (325 mm * 210 mm * 180 mm) up to 4 mice per cage with cardboard cylinder tissu, epaper, and PC tube/club house for environment enrichment and crushed cornc obbedding, autoclaved changed; weekl y.The housing temperature was 20-26°C wit ha 40-70% humidit levely and a light cycle of 12 hour light (7:00 am-7:00 pm) and 12 hours dark.
Mice were provided 0.2 pm filtered reverse, osmosis autoclaved, water and fed standard rodent chow, irradiated, ad libitum.

[0146] The U-87 MG tumo cellr weres maintained in vitro as a monolaye cultr ure in DMEM medium supplemented with 10% heat inactivat feted al bovin eserum at 37°C in an atmosphe ofre 5% CO2 in air. The cells, when in exponent ialgrowt phase,h were harvest edand quantitated by cell count erbefore tumo inoculatr ion.
Selection of Dose id="p-147" id="p-147" id="p-147" id="p-147" id="p-147" id="p-147"
[0147] The dose of ES-481 selected was based on the anti-seizure doses previousl y documented in a mice seizure model s.In addition, the dose of 20 mg/kg ES-481 was also chosen because the expecte antid -seizu dosere in humans is though tot range from approximat 80ely mg to 150 mg per day of ES-481 and thi sdose shoul bed sufficient to inhibit hyperactive electrical conduction in cancerous glioma cells To. assess the potent ialcontribution of ES-481 in combination with temozolom idein this orthotopi xenograftc model a, dose of mg/kg x 5/week x 2 week of temozolom idewas select edin combination with 20 mg/kg x /week x 3 weeks of ES-481. 37 Tumor Inoculation id="p-148" id="p-148" id="p-148" id="p-148" id="p-148" id="p-148"
[0148] After anesthesia by intraperitoneal injection of Ketamine (0.1mL/mouse), head skin of the mouse was sterilized with the 75% alcoh oland then a 2 to 3 mm length incision was made just at the right of the midline and anteri toor the interaur line.al Mice were inoculated intracranially with the tumo cellsr (2 x1q5 cells in 2 pL PBS) at the right fron tallobe 2 mm lateral from the bregma and 0.5 mm from the anteri orat a dept hof 3.5 mm. The incision was stitched using No.6 suture and then sterilize witd hpovidone iodine solution. The mice were kept warm unti theyl recovered from anesthesia The. treatments were start edat day 5 after randomizat ion.
Each grou consistedp of 10 mice.

[0156] For survival analysis, Kaplan-Mei ersurvival curves were generat ed,and a Log Rank test was performed The. event of interest was the anima ldeath. The survival time was defined as the time from the day of tumo cellr inoculati untilon one day before animal death or ethical endpoint. For each grou p,the median survival time (MST), corresponding 95% confidence interval and the increased in life-span (ILS) were calculated. All data were analyzed using SPSS 18.0 and/or GraphPa dPrism 5.0. P < 0.05 was considered statisticall signiy ficant. 39 Results Historical Data with this Model id="p-157" id="p-157" id="p-157" id="p-157" id="p-157" id="p-157"
[0157] Prio tor initiati ngthe prese ntin vivo orthotopic U-87MG human glioblastoma xenograft mouse model study with ES-481, it was well documented in thi smodel tha t,with a temozolomide dose of 75 mg/kg (data not shown) and 100 mg/kg x 5days/week x 2 week (FIG. 5), no animal survived beyond Day 30.
ES 481 Alone or In Combination with Temozolomide id="p-158" id="p-158" id="p-158" id="p-158" id="p-158" id="p-158"
[0158] Althou ghthere was no statistically-signif differicantence in overa survill val betwee vehiclen (Group 1) and ES-481 (Group 2), there was a statistically-signif dificanferencet in the weigh oft the tumors betwee Groupn 1 and Group 2. More impressive was the fact that all of the animal sin ES-481 and temozolomi (Groupde 3) survived and had no tumors presented when sacrificed at Day 41. Table 5 provides the tumo weigr hts and FIG. 6 shows the overal l survival curves for the thre groue ps.

[0159] These data suggest that in, addition to its beneficial anti-seizure/anti-epileptic therapeu effticects, the administrat ofion a selecti veTARP y8-dependent AMPA recept or antagoni likest ES-481 attenuates tumor growt inh subject affls icted with a glioma thereb y producin oneg or more of the follow ingbenefici aleffects: (a) an alleviation of one or more symptom of the glioma; (b) a dela yor slowing of glioma tumor growt and/oh metastasir s; (c) a stabilized state of a glioma tumo orr malignancy; and/or (d) an increased lifespan as compared to that expected in the absence of treatment. id="p-160" id="p-160" id="p-160" id="p-160" id="p-160" id="p-160"
[0160] Surprisingl they, data further indicated that combining the treatment of ES-481 with temozolomide, an alkylati agentng widely used in the treatment of recurrent malignant gliomas, significant andly drastical enhancedly the tumo growtr atth enuati effectson of ES-481 alone. Indeed, all of the animal streat edwith the combination of ES-481 with temozolomi de 40 survived the entire observati periodon of 40 days and none of these animal shad any measurabl tumoe weir ght.
