1.0 PROTOCOL SUMMARY AND/OR SCHEMA
Efficacyof a nti-GD2 xxxxx xxxx l a ntibody (MoAb) therapy is prove n. This is a single-arm, ope n- labe l, open access study to provide the a nti- GD2 murine IgG3 MoAb 3F8 combined with
gra nuloc yte-ma crophage colony stimulating factor (GM-CSF) to patients with high-risk
ne uroblastoma (NB). This immunotherapy has shown efficacya ga inst minima l residual disease (MRD) in suc h patie nts. 3F8 is not yet lice nsed by the Food a nd Drug Administra tion (FDA) and commerc ia lly a va ilable but is listed on the FDA site as xxxxx n designa xxx.1a
2.0 OBJECTIVES AND SCIEN TIFIC AIM S
The objec tive of this ope n access protocol is to provide 3F8 to patie nts with high-risk NB. The treatme nt IND will collect additiona l usa ge, tolerability a nd safetydata.
3.0 BACK GROUND AND RATIONALE
3.1 Dise ase background: NB is the most common extracrania l solid tumor of childhood; 50-60% of patie nts prese nt with an unresectable prima ry tumor a nd metastases in bone marrow (BM).1 Inte nsive induction che motherapy a nd aggressive surgery ha ve improved re mission rates in xxxxx xxxxx nts2-4; results ha ve been less impressive in adolesce nts a nd adults in whom NB is espec ia lly c he moresistant.5,6 Realization of an effective xxxxxx xx for eradicating MRD ha s remained a formidable c halle nge. Post-surgica l use of loca l radiotherapy he lps control MRD in the primary site.7 Mye loabla tive therapy with a utologous ste m-ce ll tra nspla ntation (ASC T) has been the most common approac h for eradicating MRD in dista nt sites. The vita min A derivative 13-cis-retinoic ac id (isotretinoin) he lped to prolong relapse- free surviva l in a ra ndomized study.8 Immunotherapy using the a nti- GD2 c h14.18 MoAb plus GM-CSF and interle ukin-2 in a lterna ting c ycles improved outcome in a ra ndomized study.9 The se results ha ve made treatme nt with isotre tinoin a nd anti-GD2 MoAb sta ndard of care for high-risk NB.
3.2 Rationale for immunothe rapy : Various strategie s have undergone c linica l testing to induce or a ugme nt immune- media xxx attack aga inst ca nce x. Xxxx ver, few c linica l trials have used xxxxx xxxx l a ntibody-targeted immunothe rapy a ga inst solid tumors in childre n or adults, espec ia lly with antibody-depe nde nt ce llular c ytotoxic ity (ADCC) as t he princ ipa l unde rlying immune cytotoxic mec ha nism. Also, an antineoplastic role for gra nuloc ytes has received sca nt atte ntion.10 A treatme nt progra m combining 3F8 a nd GM-CSF thus represe nts an a ttempt to he lp fill a gap in the e merging fie ld of immunotherapy.
3.3 Rationale for 3F8 : 3F8 is a murine IgG3 MoAb tha t is well suited for targeted immunotherapy. The reasons are se xxxx x. First, the inte nsive c he mothe rapy required to produce the minima l disea se state optima l for immunotherapy in NB patie nts res ults in prolonged se vere lymphope nia.11 This setting is unfa vorable for active immunotherapy but a llows passive immunotherapy since the patie nt will be unable to reject alloge ne ic, xe noge ne ic, or ge netica lly- engineered a ntibodie s. Second, 3F8 recognizes the ga nglioside GD2.12 This targe t a ntige n is expressed at high density on NB (but ha s restric xxx distribution in xxxxx l huma n tissues), is not modulated from the cell surface whe n bound by antibodies, a nd is ge netica lly stable (unlike tumor- assoc ia xxx a ntige ns suc h as immunoglobulin idiotypes on lymphoma ce lls).13-15 Third, scintigraphy using 131I-3F8 confirms tha t 3F8 loca lizes se lec tive ly to GD2(+) tumor deposits in patie nts.16 The exce lle nt targeting pote ntia l of 3F8 was evidenced by its high tumor to non-tumor ratio, the high perce nt injected dose per gra m uptake, a nd the limited, if any, nonspecific liver a nd spleen
uptake.16,17 Fourth, 3F8 media tes destruction in vitro of GD2(+) huma n solid tumor ce lls by huma n comple me nt18 and by human lymphoc ytes, cultured monocyte s, and ne utrophils.19-21 Fina lly, the capac ity of 3F8 to activa te comple me nt on NB ce lls (which lack decay acce xxxx xxxx factor22) ra ises the possibility, not only of comple me nt- mediated lysis in patie nts, but also of the re lease of
comple me nt fragme nts that ma y e lic it an infla mma tory influx of gra nuloc ytes capable of lysing 3F8-
labe led tumor ce lls. F urthe rmore, the deposition of comple me nt fragme nts C3b a nd iC3b on NB ce lls may enha nce ADCC beca use the receptor for iC3b – variously ca lled Mac-1, CR3, CD11b/CD18, or άMβ2-inte grin – is a key ele me nt in a nti- GD2 MoAb- mediated tumor cell kill by ne utrophils,23,24 whic h are the most abunda nt circulating c lass of le ukoc yte.
3.4 Rationale for GM -CSF: GM-CSF has the pote ntia l for a mplifying 3F8 a ntitumor activity in patie nts via effects on gra nuloc yte s a nd tissue -based macropha ges. Reasons for combining GM-CSF with 3F8 include the following. F irst, gra nuloc yte production is only tra nsie ntly suppressed with che motherapy a nd GM-CSF increases numbers of c ircula ting neutrophils a nd eosinophils, does not affect comple me nt le ve ls, a nd is well tole rated compared to other cytokines suc h as interleukin-
2.2 5 Second, gra nuloc ytes from patie nts receiving c he motherapy and from xxxxx l volunte ers are effective in mo unting ADCC a ga inst NB ce lls via non-oxida tive mec ha nisms, a nd GM-CSF enha nces this cytotoxicity.24,26-30 Third, eosinophilic infiltra tion of some ca ncers has fa vorable prognostic significa nce, a nd eosinophils e xhibit pote nt a ntitumor activity in animal mode ls.31,32 Fourth, activated monoc ytes- mac ropha ges effic ie ntly pha goc ytose N B ce lls, a nd e xposure in vitro or in vivo to GM- CSF primes monoc ytes- macropha ge s for grea ter a ntineoplastic cytotoxic ity.33-38 Fifth, GM-CSF enha nce s the prolife ration, ma turation, a nd function of a ntige n-prese nting ce lls, inc luding antige n processing a nd prese nta tion by macropha ges a nd de ndritic ce lls25,39,40 - effects that might promote induction, or antitumor activity, of an idiotypic network. 41-44 Fina lly, GM-CSF is not a growth factor for NB ce lls in vitro.45
3.5 GM -CSF-me diatedactivationof ne utrophils : Neutrophils are the predomina nt c lass of circula ting le ukoc ytes; c he motherapy only tra nsie ntly decreases the ir numbers a nd large ly spares the ir c ytotoxic capabilities. The se features are adva nta geous for immune-based attack a ga inst cance r.10 We and others ha ve shown tha t Mac-1 (CD11b/CD18), FcRII, a nd Fc RIII are required for optima l ADCC in a syste m using huma n ne utrophils as effectors, huma n N B ce lls as targe ts, a nd c linica lly active a nti- GD2 MoAbs as mediators.23,24 Effic ie nt tumor-ce ll kill occ urs despite the large size of the targets (whic h precludes a role for pha goc ytosis) a nd the ir relative resista nce to reac t ive oxyge n species.29 GM-CSF enha nceme nt of ADCC in this syste m corre la tes with upre gulation of Mac-1 and with incre ased e xoc ytosis of azurophil (primary) gra nules whic h conta in cathepsin G a nd defe nsins capable of lysing N B ce lls.30 To eluc idate the c ytotoxic mec hanisms of anti-GD2 MoAb- media xxx ADCC, we used blocking MoAbs, ne utrophils de void of Mac-1 (from donors with le ukoc yte adhesion defic ie nc y), a nd ne utrophils that do not generate reactive oxyge n species (from donors with c hronic gra nulomatous disea se),23 while othe rs used blocking MoAbs, e lec tron microscopy, a nd ne utrophils from hea lthy donors as well as from patie nts.24 Activa tion of ne utrophils by GM-CSF is correlated with improved anti-NB effects of treatme nt with a nti-GD2 MoAb.46
3.6 Clinical e xpe rience with 3F8 plus GM -CSF: The optima l method of using GM- CSF with the aim of enha ncing ADCC in patie nts with solid tumors has only rece ntly been eluc xxx xxx. In the past, we c hose to administe r GM-CSF by a 2- hr iv infusion (followed by a 1-hr interval before starting 3F8 infusion) because GM-CSF disappea rs rapidly (<2-3 hr) from the blood with that schedule.47,48 We wished to a void the prolonged (>12 hr) bioa ctive le ve ls in blood assoc ia xxx with the
subc uta neous (sc) route; our concern was tha t high serum le ve ls of GM-CSF might impede gra nuloc yte trafficking into tissues.49 Xxxx ve r, for circulating tumor ce lls in BM or blood, this conce rn is dwarfed by the more pote nt antitumor effects fromprolonged c ytokine e xposure following subc uta neous injection.25
The 03-077 study of 3F8+sc GM-CSF immunothe rapy plus isotretinoin e nrolled patie nts in 1st comple te/ve ry good partia l re mission (CR/VGP R) (n=85), patie nts with primary refractory NB in BM (n=79), a nd patie nts in >2 CR/VGP R (n=101). Sa lie nt findings included:
1) Ac ute toxicitie s were ma na geable which a llowed outpa tie nt treatme nt. This finding sta nds in xxxxx contrast with studie s using other anti-GD2 MoAbs either alone or in combination with interle ukin-2, where treatme nt is inpatie nt, often in an intensive care unit, with complic ations suc h as capillary leak syndrome.9
2) For patie nts in 1st CR/VGPR, prior mye loabla tive therapy + ASCT had no impac t on 5- year progression-free surviva l (PFS) 62% or xxx xxxx surviva l (OS) 81%.50 This supports the welcome possibility of a voiding the risk of significa nt ac ute a nd long-term toxic ities of mye loabla tive therapy.
3) For patie nts with prima ry refractory NB, CR rate in BM by histology was 87% a nd CR rate of metaiodobe nzylgua nidine (MIBG) scans was 38%. These results vividly doc ument the anti-NB activity of a nti- GD2 MoAb immunotherapy, i.e., the possibility of overcoming histologica lly- and/or radiologica lly- visible c he moresista nt NB in BM using an a nti- GD2 MoAb regime n tha t has ma na geable toxic ity a nd is administe red outpatie nt.
4) Patie nts treated in >2 CR/VGPR achie ved 48- month PFS 33% a nd OS 53%, with no adve rse impac t if patie nts had received anti-GD2 MoAb a nd isotre tinoin as part of initial (pre-re lapse) therapy a nd with only 2/35 very long-term relapse- free survivors having received ASCT as part of xxxxx xx. These results are noteworthy, give n tha t studies show <5% long-term OS after relapse51-55 and a nti- GD2 MoAb, isotretinoin, a nd ASCT are sta nda rd treatme nts for newly-dia gnosed patie nts.56 Inde ed, the results support a c ha nge in mind-set: no longe r should relapse of high-risk NB be considered “invariably xxxxx l”,57 but rather a cura tive xxxxxx xx should be applied.
5) Positive MRD after 2 c yc le s of 3F8+scGM-CSF was a significa ntly adverse indepe nde nt prognostic factor for all groups of patie nts.50,58,59 This finding should be taken into account whe n determining subseque nt therapy in a given patient.
6) Corre lative studie s highlight the a nti- neoplastic pote nc y of mye loid effectors whe reas lymphoc ytes are the effectors usua lly he ra lded in ca ncer immunothe rapy.
7) GM-CSF by sc route is associated with be tter PFS and OS tha n by iv route,60 as used in the predecessor study of 3F8+ivGM-CSF. 61
3.7 Is otre tinoin (13 -cis-retinoic acid) was shown in a ra ndomized na tiona l study to decrease the risk of relapse in patie nts treated in complete re mission.8 This age nt has subseque ntly become sta ndard of care for N B patie nts in complete re mission. It will be used in this protocol after patie nts are evalua xxx for response (a nd for toxic ity) to 3F8/GM-CSF.
3.8 Inte rpre tatio ns and implicatio ns The ease of administra tion of the treatme nts (a subc uta neous injection, whic h is give n at home, a nd a 30- minute intra ve nous infusion in the
outpatie nt c linic), plus the ir tra nsie nt ac ute side-effects, are compatible with wide spread usa ge of this regimen be yond our hospita l – a strong positive factor in furthering product de ve lopme nt.
In addition to the outpatie nt treatme nt with a nti- GD2 MoAb, the Memorial S loa n-Kette ring Cancer Center (MSKCC) ne urobla stoma treatme nt progra m remains unique in that ASC T is not included a nd the immunothe rapy is a va ilable for patie nts in >2nd C R/VGP R. Results to date, as summa rized in section 3.6, are highly e ncouraging a nd ma y have implications world-wide.

5.0 THERAPEUTIC/DIAGNOSTIC AGENTS
5.1 3F8 xxxxx xxxx l a ntibody (IND number of BB-IND-8449)
m3F8 is an investigationa l new drug de ve loped at MSKCC and ma nufac tured by a qua lified CMO in complia nce with GMP guida nce appropria te for phase I c xxxxxx x xxxx ls. The final produc t specifications, a na lytical test me thods a nd stora ge conditions/stability are described in the CMC section of this IND. Brie fly, m3F8 is purified by column chromatography followed by viral filtra tion a nd fina le sterile filtra tion. The fina l produc t is tested to assure tha t it is free of aggre gates, nuc leic ac id, murine viruses, bacteria, fungi, mycoplasma a nd pyroge ns. m3F8 is also tested for a ntibody specificity. For iv administration, 3F8 should be diluted into 10 ml 5% huma n serum a lbumin a nd millipore (0.2 µm) filtered before use. Route of Administra tion: iv infusion.
5.2 Sargra mostim (YEAST-DERIVED HUMAN RECOMBINANT GRANULOCYTE- MACROPHAGE COLONY STIMULATING FACTOR; GM-CSF)
5.2.1 Source and Pharmacology: Yeast derived recombina nt huma n GM-CSF.
5.2.2 Supplier: LEUKINE (sargra mostim) is distributed by Ge nzyme Corpora tion, Cambridge, MA a nd ma nufac tured by Ba yer HealthCare P ha rmace utica ls, Seattle, WA.
5.2.3 Formulation and Stability: Sargra mostim is a va ilable as a sterile, white, preserva tive- free, 250 mc g single use via l of lyophilized powder or a 500 mc g/1 mL injectable solution.
The 250 mcg via ls require aseptic reconstitution with 0.5 mL Sterile Water for Injection, USP (without preserva tive ). During reconstitution, the Sterile Water for Injec tion, USP should be directed at the side of the via l and the xxxxx nts ge ntly swirled to a void foa ming
during dissolution. Avoid e xce ssive or vigorous agitation; do not shake. The reconstituted sargra mostim solutions are clear, colorless, isotonic with a pH of 7.4 ± 0.3, a nd conta in 500 mc g/mL of sargra mostim. The single-use 250 mc g via ls contain no a ntibacteria l preserva tive, and the refore should be administered as soon as possible, and within 6 hours following reconstitution. The y are inte nded for single use only a nd should not be re-entered or re used. Do not sa ve a ny unused portion for later administration. Do not use be yond the e xpira tion date printed on the via l.
Via xx xxxxx ining 500 mc g/1 mL of sargra mostim are already in solution and are multiple dose vials. For subcuta neous administration, further dilution is not required. Liquid sargra mostim may be stored for up to 20 da ys at 2-8°C once the vial has been entered. Disca rd a ny remaining solution after 20 da ys.
Store sargra mostim powder, or reconstituted solutions, under refrigeration at 2-8°C (36-46°F); do not free ze or shake.
Aseptic tec hnique should he employed in the preparation of all sargra mostim solutions. To assure correct conce ntration following reconstitution, care should be e xerc ised to eliminate any air bubbles from the needle hub of the syringe used to prepare t he dilue nt. Parenteral products should be inspec xxx visually for particula te matter a nd discolora tion prior to administration whe ne ver solution a nd conta iner permit.
5.2.4 Route of Administration: Subcuta neous
5.3 13-cis-Re tinoic Acid (NDC #0000-0000-00,0004-0169, 0004-0156-01-
ISOTRETINOIN, ACCUTANE)
5.3.1 Source and Pharma cology: The e xact mec ha nism of retinoic acid- induced matura tion of tumor ce lls is not known. In ne uroblastoma cell lines it has been shown to down regulate MYCN RNA and protein e xpression, a nd suc h down re xxxx tion correlates with the ability of isotre tinoin to induce tumor cell growth arrest. Rece nt studie s using ge ne tra nsfection direc tly implica te down re gulation of MYCN expre ssion by isotretinoin as a key eve nt in achie ving susta ined arrest of ne uroblastoma cell prolife ration. Retinoic acid also appears to enhance xxxxx l hematopoietic differe ntiation by increasing the responsive ness of mye loid a nd erythroid proge nitor ce lls to the action of mye loid colony stimulating activity and erythropoie tin, respective ly. Me tabo lism: Retinoic ac id is 99.9% bound in plasma (almost entire ly to albumin) a nd has a ha lf- life of 10-20 hours. The major me tabolite is 4-
oxoisotretinoin, a nd e xcre tion is in the urine a nd feces. A single oral dose of 100mg/m2
isotretinoin will produce peak plasma leve ls of 1-2mM. The mea n peaktime as 3.2 hours after 80mg ora lly, with a termina l t½ of 10 to 20 hours. Administering 160 mg/m2/day to childre n after ASCT ha s beenshown to achie ve 13-c is-retinoic acid le ve ls of 5 to 7 micromula r.
5.3.2 Formulation a nd Stability: Isotretinoin, whic h is the 13-cis xxxxx r of retinoic ac id, will be used. This is a ye llow--orange crysta lline powder with a molec ula r weight of
300.44. Isotretinoin is sensitive to light a nd oxyge n, a nd so it should not be re moved from the capsule for longe r than one hour prior to administration to the patie nt a nd it should be kept in subdued light as much as possible.
5.3.3 Guide lines for Administration: Take orally with fat-conta ining food or milk to enha nce absorption. Administra tion of the entire capsule is to be encouraged a nd sma ll childre n can be trained to swallow them using similar sized ca ndy.
5.3.4 Supplier: Isotretinoin is a va ilable commerc ia lly under the trade na me ACCUTANE (Roc he Xxxxxxxx xxxx) in 10mg, 20mg, a nd 40mg soft ge latin capsules. See package insert for further information.

8.7 Pregna ncytest, if applicable
9.0 TREATMENT/INTERVENTION PLAN
9.1 Schedule : The total dosa ge of 3F8 per cycle is 100 mg/m2, administered at 20 mg/m2/day a nd infused iv over ~1.5 hr or le ss (0.5 hr is c ustomary), with a na lgesics a nd antihista mines used as needed for e xpected side -effects. 3F8 is started after GM-CSF administration. GM-CSF is dosed at 250 mc g/m2/day from day –5 to day +1 (Wednesda y to Tuesda y is c ustomary), a nd is 500 mc g/m2/day thereafter (i.e., on da ys +2 to +4; Xxxxxxxx y to Xxxxx y), as in the predecessor protocol. 61 Patie nts come off study for PD or a life- threatening grade 4 toxic ity from 3F8; othe rwise, patients will continue treatme nt through 24 months. It is e xpec xxx that patie nts will receive ~4-to-10 cycles. Patie nts may receive local radiation the rapy.
For Group 1 and 2 patie nts (enrolled respectively on study in 1st or >2nd CR/VGP R,
i. e., with no evide nce of disease), the break between end of a c yc le a nd start of ne xt cyc le is approxima tely 2-to-4 weeks through 4 c yc le s; subsequent breaks are ~6-8 weeks. Isotretinoin is started after c yc le 2 of 3F8/GM-CSF. It is only to be started after c yc le 1 if HAMA deve lops a nd precludes time ly administration of c yc le 2. Road map/sc hema is in section 4.2.
For Group 3 patie nts (e nrolled on study for treatme nt of prima ry refractory disea se), the break between e nd of a cyc le of 3F8/GM-CSF and start of ne xt c yc le is approxima tely 2-
to-4-weeks through 4 cyc les after achie ve ment of CR in BM; subseque nt breaks are ~ 6-8 weeks. Isotretinoin is started after c yc le 2 of 3F8/GM-CSF. It is only to be started after cyc le 1 if HAMA deve lops a nd preclude s time ly administra tion of cyc le 2. Road ma p/sc he ma is in section 4.2.
Patie nts who deve lop early HAMA, whic h precludes time ly treatme nts with 3F8/GM- CSF, are e ligible to receive low-dose ma inte na nc e regime ns suc h as irinoteca n a lone,68 te mozolomide a lone,69 irinoteca n-te mozolomide,70 or cyc lophospha mide-topoteca n.71 These patie nts can also receive a nti- HAMA a ge nts such as rituxima b a nd c yc lophospha mide. The y resume treatment with 3F8/GM-CSF if HAMA becomes ne gative.
9.2 3F8/GM-CSF treatme nt sc hedule (one c yc le).
Da ys -5 to -1: GM-CSF 250 mc g/m2/da y, subc uta neously. Da ys 0 a nd +1: GM-CSF 250 mc g/m2/da y, subc uta neously.
3F8 20 mg/m2/day by iv infusion ove r ~1.5 hr or le ss (usua lly 0.5 hr).
Da ys +2 to +4: GM-CSF 500 mc g/m2/da y, subc uta neously.
3F8 20 mg/m2/day by iv infusion ove r ~1.5 hr or le ss (usua lly 0.5 hr).
Note: The da ily GM-CSF is not administered if the absolute ne utrophil count (ANC) is >20,000/ µl. The last doc ume nted ANC count will be used to determine whe ther GM-CSF will be administered or not. If HAMA de velops, cyc les are deferred until HAMA titer decreases to <1000 Elisa units/ml. Emla cream (lidoca ine 2.5% a nd priloca ine 2.5%) can be used to pre ve nt pain from GM-CSF shots.
9.3 Isotretinoin is administered at 160 mg/m2/d, divided into two doses, x14 days. This treatme nt can be repeated after a minimum rest period of 14 days, for a total of 6 c yc les. I t is not taken on the same da ys as 3F8. All patients receive a minimum of 2 c ycles of 3F8/GM- CSF before starting isotretinoin (only to be started after cyc le 1 if HAMA de ve lops a nd precludes timely administra tion of c yc le 2). All patie nts take a total of 6 c yc le s of isotretinoin, but those patie nts who ha ve persiste nce of disease (but no progressive disease) can take this age nt until BM a nd MIBG show CR. Dose reductions due to e xpec xxx side effects of isotretinoin (e.g., he adac hes, dry skin, etc.) are a llowed.
10.0 EVALUATION DURING TREATMENT/IN TERVENTION

13.2 All patie nts come off study if there is a life-threa tening grade 4 toxicity c lea rly attributable to 3F8.
13.3 The investigators will make e very reasonable effort to keep each patie nt in the study until all pla nned treatme nts a nd assessme nts ha ve been performed. The investiga tors may discontinue study drug treatme nt for the following reasons:
• Adve rs e e ve nts , including unacceptable toxic ity or e xacerbation of underlying disease, associated with study drug administration a nd necessitating discontinuation of treatme nt. Patie nts who are removed from the study due to adverse e ve nts will be treated a nd followed according to established, acceptable medica l practic e. All pertine nt informa tion conce rning the outcome of suc h treatme nt will be e nte red in the Case Report Form or on the Serious Eve nt Report, as applicable.
• Withdrawal of co ns e nt. The patie nt's desire to withdraw from the study may occ ur at any time. The investiga tor should carefully consider whethe r the patie nt’s withdra wal of conse nt is due to an adverse e ve nt, a nd if so, record the adverse eve nt as the reason for withdrawa l.
• Withdrawal by the phys ician for c linica l reasons not related to study drug treatme nt, for e xa mple, c linica l need to administer a concomita nt medication that is e xc luded by the protocol, in the abse nc e of an adve rse e ve nt.
• Vio lationof the s tudy pro tocol, including fa ilure to return for required treatme nts or
assessme nts.
14.0 BIOSTATISTICS
This tria l concerns the a nti-NB activity of 3F8/GM-CSF. The response e ndpoints are relapse- free surviva l for patie nts treated in C R/VGP R (Groups 1 a nd 2) a nd CR of BM disease for patie nts with prima ry refractory NB (Group 3). Response will be assessed a nd compa red to historica l data, in the xxxxx xt of the large e xpe rie nce with the 03-077 predecessor study (section 3.7).
We will treat NB patients with 3F8/GM-CSF provided the y mee t e ligibility criteria of this protocol. This protocol will re ma in ope n until such a time tha t 3F8 is licensed for broader use (i.e., as an FDA- approved drug). All enrolled patie nts who receive a ny 3F8 will be conside red in the e va luation of safety/toxic ity.
