Title: Fdg-pet evaluation of ewing&#39;s sarcoma sensitivity

Description:
This application is a divisional application of U.S. patent application Ser. No. 12/879,359; filed Sep. 10, 2010; which claims the benefit of U.S. provisional patent application no. 61/241,137; filed Sep. 10, 2009; each of which is herein incorporated by reference in its entirety. 
    
    
     FIELD OF THE INVENTION 
     The field of the invention relates, generally, to methods for treatment of patients with tumors with an IGF1R inhibitor wherein the tumors have been evaluated by PET scan for sensitivity to the inhibitor. 
     BACKGROUND OF THE INVENTION 
     Early prediction of response to a chemotherapeutic treatment is of great value to avoid unnecessary toxicity of ineffective treatment and to get a chance to receive another effective treatment at an early stage. 
     Increased uptake of  18 F-fluorodeoxyglucose (FDG) measured by positron emission tomography (PET) reflects glucose metabolism and proliferative activity of tumor cells. Metabolic imaging with FDG-PET has been used for staging, restaging, and evaluating treatment efficacy in various cancers. Some studies have indicated that FDG-PET is useful for the early evaluation of tumor response to anticancer drugs. 
     FDG-PET has been used to predict chemotherapeutic efficacy of Ewing&#39;s sarcoma tumors. However, the value of FDG-PET scans performed at an early point in a treatment regimen has not been heretofore realized. Specifically, whether the observation of an effect on tumor metabolism (or lack of an effect) at an early point will predict overall sensitivity of the tumor to a given therapy is uncertain. Clearly, a study that clarifies this uncertainty would be useful and would suggest a new method for quick evaluation of Ewing&#39;s sarcoma tumor sensitivity. 
     SUMMARY OF THE INVENTION 
     The present invention addressed this need by providing a method for making an early determination as to the efficacy of an IGF1R inhibitor treatment regimen for Ewing&#39;s sarcoma by way of an FDG-PET analysis of the tumor. 
     The present invention provides, in part, a method for treating a Ewing&#39;s sarcoma tumor (e.g., recurrent or relapsed Ewing&#39;s sarcoma), in a subject (e.g., a human), comprising evaluating glucose metabolism of the tumor after the subject has received a first dose of IGF1R inhibitor (e.g., an isolated antibody or antigen-binding fragment thereof such as an isolated antibody or antigen-binding fragment thereof comprising CDR-H1, CDR-H2 and CDR-H3 of the heavy chain immunoglobulin variable region whose amino acid sequence is set forth in SEQ ID NO: 10, 12, 13, 14, 15, 16, 17 or 18; and CDR-L1, CDR-L2 and CDR-L3 of the light chain immunoglobulin variable region whose amino acid sequence is set forth in SEQ ID NO: 2, 4, 6, 8, 19, 20, 21, 22, 23 or 24; e.g., wherein the antibody or fragment heavy and/or light chain variable region is linked to an immunoglobulin constant domain such as for example, a kappa light chain, a lambda light chain, a gamma-1 heavy chain, a gamma-2 heavy chain, a gamma-3 heavy chain and/or a gamma-4 heavy chain), but before a second dose of the inhibitor; or within 14 days of a first dose of IGF1R inhibitor but before a second dose of said inhibitor; wherein treatment with the IGF1R inhibitor is discontinued if glucose metabolism does not significantly decrease or remain constant after said first dose; and continuing treatment with the IGF1R inhibitor if glucose metabolism does significantly decrease or remain constant after said first dose. Similar methods for determining if a Ewing&#39;s sarcoma tumor is sensitive to an IGF1R inhibitor; for selecting a patient for treatment with an IGF1R inhibitor; for identifying a patient with an IGF1R sensitive tumor; and for evaluating dosage of an IGF1R inhibitor are encompassed by the present invention. These methods are discussed in greater detail herein, e.g., below under the “Biomarkers” section. In an embodiment of the invention, glucose metabolism is evaluated by administering labeled glucose and monitoring its metabolism by the tumor, for example, wherein glucose metabolism is evaluated by  18 F-fluorodeoxyglucose positron emission tomography (FDG-PET). In an embodiment of the invention, the method comprises the step of continuing treatment with the IGF1R inhibitor if glucose metabolism decreases by about 15% to about 25% after said first dose. In an embodiment of the invention, the subject is administered an IGF1R antibody (e.g., as discussed herein) at a dose of about 1 to about 20 mg/kg every two weeks; e.g., about 10 mg/kg every two weeks). In an embodiment of the invention, the subject is administered the IGF1R inhibitor in association with a further chemotherapeutic agent such as aprepitant and/or any other further chemotherapeutic agent discussed herein, for example, below under the “Further chemotherapeutic agents” section. 
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     The present invention provides a method for evaluating whether a Ewing&#39;s sarcoma tumor will be sensitive to an IGF1R inhibitor. The method includes evaluating the tumor&#39;s metabolism of FDG via PET scan. Data presented herein established that a reduction in FDG metabolism, as measured by PET scan, when performed within one to two weeks of initial treatment, is highly predictive of the sensitivity of the tumor for the IGF1R inhibitor. 
     Biomarkers 
     The present invention encompasses a method for treating a Ewing&#39;s sarcoma tumor, in a subject, comprising evaluating glucose metabolism of the tumor after the subject has received a first dose of IGF1R inhibitor, but before a second dose of the inhibitor; or within 14 days of a first dose of IGF1R inhibitor (e.g., 7-14 days, 7-10 days, 1 days, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 8 days, 9 days, 10 days, 11 days, 12 days, 13 days or 14 days) but before a second dose of said inhibitor; wherein treatment with the IGF1R inhibitor (e.g., an isolated anti-IGF1R antibody such as any of those discussed herein) is discontinued if glucose metabolism does not significantly decrease or remain constant after said first dose (e.g., as compared to the level of glucose metabolism before the first dose); and continuing treatment with the IGF1R inhibitor if glucose metabolism does significantly decrease or remain constant after said first dose (e.g., as compared to the level of glucose metabolism before the first dose). 
     For example, in an embodiment of the present invention, the step of evaluating and comparing glucose metabolism of the tumor in a subject receiving an IGF1R inhibitor treatment regimen includes the steps of: 
     (i) administering the radiolabeled glucose to a subject, e.g., FDG (e.g., about 10 to about 20 mCi, e.g., about 10 mCi, about 11 mCi, about 12 mCi, about 13 mCi, about 14 mCi, about 15 mCi, about 16 mCi, about 17 mCi, about 18 mCi, about 19 mC or about 20 mCi), for example via intravenous injection; and
 
(ii) allowing the radiolabeled glucose to incubate for about 75 minutes;
 
(iii) PET scanning or PET/CT scanning at least part of the subject&#39;s body, e.g., a whole body scan from skull base to proximal femurs; and
 
(iv) identifying and evaluating any detected levels of tumoral glucose metabolism in the subject.
 
     If the levels of tumoral glucose metabolism before and after initial treatment with an IGF1R inhibitor are to be compared, the following further steps can be performed: 
     (a) administering a first dose of the IGF1R inhibitor (e.g., 10 mg/kg of anti-IGF1R antibody) to the subject;
 
(b) waiting about 7-14 days (e.g., 7-14 days, 7-10 days, 1 days, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 8 days, 9 days, 10 days, 11 days, 12 days, 13 days or 14 days; but before any second dose is administered) or until a second dose is due under the selected anti-IGF1R treatment regimen; then re-evaluating glucose metabolism by any tumor detected in the first scan(s), e.g., by:
 
(1) administering the radiolabeled glucose to a subject, e.g., FDG (e.g., about 10 to about 20 mCi, e.g., about 10 mCi, about 11 mCi, about 12 mCi, about 13 mCi, about 14 mCi, about 15 mCi, about 16 mCi, about 17 mCi, about 18 mCi, about 19 mC or about 20 mCi), for example via intravenous injection; and
 
(2) allowing the radiolabeled glucose to incubate for about 75 minutes;
 
(3) PET scanning or PET/CT scanning at least part of the subject&#39;s body, e.g., a whole body scan from skull base to proximal femurs;
 
(4) identifying and evaluating any detected levels of FDG metabolism in the subject;
 
(5) comparing the levels of glucose metabolism detected before and after the first dose of IGF1R inhibitor.
 
     FDG-PET scans are well known techniques in the art and are well within the abilities of a practitioner of ordinary skill in the art. 
     In an embodiment of the invention, a significant decrease in glucose (e.g., FDG) metabolism is any measurable amount of decrease that would be recognized by a practitioner of ordinary skill in the art, under the circumstances and in view of the particularities of the patient or subject&#39;s clinical state, would recognize as significant. In an embodiment of the invention, a significant decrease is between about 15% and about 25% (e.g., about 15-20%, about 15-25%, about 20-25%, about 15%, about 16%, about 17%, about 18%, about 19%, about 20%, about 21%, about 22%, about 23%, about 24%, about 25%). 
     The magnitude of radioactivity (e.g., when using an FDG marker) in a tumor cell can be converted from PET signal to absolute radiation units (e.g., using methods commonly known in the art) when evaluating whether a decrease of glucose metabolism has occurred. Alternatively, arbitrary units of PET signal are merely compared when determining whether a decrease in glucose metabolism has occurred. In an embodiment of the invention, tumor-to-background ratios of FDG uptake are compared when making a determination as to whether a decrease of glucose metabolism has occurred. 
     The present invention further encompasses a method for evaluating whether a Ewing&#39;s sarcoma tumor is sensitive to an IGF1R inhibitor comprising evaluating glucose metabolism of the tumor after the subject has received a first dose of IGF1R inhibitor, but before a second dose of the inhibitor; or within 14 days of a first dose of IGF1R inhibitor (e.g., 7-14 days, 7-10 days, 1 days, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 8 days, 9 days, 10 days, 11 days, 12 days, 13 days or 14 days) but before a second dose of said inhibitor; wherein the tumor is determined to be insensitive to the IGF1R inhibitor (e.g., an isolated anti-IGF1R antibody such as any of those discussed herein) if glucose metabolism does not significantly decrease or remain constant after said first dose (e.g., as compared to the level of glucose metabolism before the first dose); and wherein the tumor is determined to be sensitive to the IGF1R inhibitor if glucose metabolism does significantly decrease or remain constant after said first dose (e.g., as compared to the level of glucose metabolism before the first dose). 
     The present invention further encompasses a method for evaluating dosage of an IGF1R inhibitor for treatment of a Ewing&#39;s sarcoma tumor comprising evaluating glucose metabolism of the tumor after the subject has received a first dose of IGF1R inhibitor, but before a second dose of the inhibitor; or within 14 days of a first dose of IGF1R inhibitor (e.g., 7-14 days, 7-10 days, 1 days, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 8 days, 9 days, 10 days, 11 days, 12 days, 13 days or 14 days) but before a second dose of said inhibitor; wherein the dose is determined to be too low if glucose metabolism does not significantly decrease or remain constant after said first dose (e.g., as compared to the level of glucose metabolism before the first dose); and wherein the dose is determined to be sufficient if glucose metabolism does significantly decrease or remain constant after said first dose (e.g., as compared to the level of glucose metabolism before the first dose). 
     The present invention further encompasses a method for identifying a subject with a Ewing&#39;s sarcoma tumor that is sensitive to an IGF1R inhibitor comprising evaluating glucose metabolism of the tumor after the subject has received a first dose of IGF1R inhibitor, but before a second dose of the inhibitor; or within 14 days of a first dose of IGF1R inhibitor (e.g., 7-14 days, 7-10 days, 1 days, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 8 days, 9 days, 10 days, 11 days, 12 days, 13 days or 14 days) but before a second dose of said inhibitor; wherein the subject is identified as having an insufficiently sensitive or insensitive tumor if glucose metabolism does not significantly decrease or remain constant after said first dose (e.g., as compared to the level of glucose metabolism before the first dose); and wherein the subject is identified as having a sufficiently sensitive tumor if glucose metabolism does significantly decrease or remain constant after said first dose (e.g., as compared to the level of glucose metabolism before the first dose). 
     A method for selecting a subject with a Ewing&#39;s sarcoma tumor for receipt of an IGF1R inhibitor treatment of the tumor comprising evaluating glucose metabolism of the tumor after the subject has received a first dose of IGF1R inhibitor, but before a second dose of the inhibitor; or within 14 days of a first dose of IGF1R inhibitor (e.g., 7-14 days, 7-10 days, 1 days, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 8 days, 9 days, 10 days, 11 days, 12 days, 13 days or 14 days) but before a second dose of said inhibitor; wherein the subject is not selected if glucose metabolism does not significantly decrease or remain constant after said first dose (e.g., as compared to the level of glucose metabolism before the first dose); and wherein the subject is selected if glucose metabolism does significantly decrease or remain constant after said first dose (e.g., as compared to the level of glucose metabolism before the first dose).

     In an embodiment of the invention, V H 1 is paired, in an antibody or antigen-binding fragment thereof, with V L a; V H 2 is paired, in an antibody or antigen-binding fragment thereof, with V L b; V H 3 is paired, in an antibody or antigen-binding fragment thereof, with V L c; V H 4 is paired, in an antibody or antigen-binding fragment thereof, with V L d; V H 5 is paired, in an antibody or antigen-binding fragment thereof, with V L e; and/or V H 6 is paired, in an antibody or antigen-binding fragment thereof, with V L f. Methods comprising use of an anti-IGF1R comprising one or more CDRs (e.g., 3 light chain CDRs and/or 3 heavy chain CDRs) from the variable regions set forht herein (e.g., (a)-(f) set forth above) are also included within the scope of the present invention. 
     Positron Emission Tomography (PET)/Computed Tomography (CT) 
     Positron emission tomography (PET) is a nuclear medicine imaging technique which produces an image or picture (e.g., in 3 dimensions) of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide (tracer), which is introduced into the body on a biologically active molecule. Images of tracer concentration (e.g., in 3-dimensional space) within the body can be reconstructed by computer analysis. In modern scanners, this reconstruction is often accomplished with the aid of a CT X-ray scan performed on the patient during the same session, in the same machine. 
     A typical tracer is the biologically active molecule FDG, an analogue of glucose. FDG is [ 18 F]-fluorodeoxyglucose. The concentrations of tracer imaged reflect tissue metabolic activity, in terms of regional glucose uptake. Although use of this tracer results in the most common type of PET scan, other tracer molecules are used in PET to image the tissue concentration of many other types of molecules of interest. 
     “CT” stands for computed tomography. CT uses x-rays and a computer to make an image of sections of your body. A CT scan shows a subject&#39;s organs, bones, and tissues in greater detail than regular x-rays do. For a CT scan, the subject will, generally, receive a contrast enhancing agent by intravenous line (IV), which helps produce an even clearer image. CT exposes the subject to a small amount of radiation. 
     A PET/CT is an imaging tool combines 2 different types of imaging into 1 procedure. PET and CT together produce a more accurate picture of the body than either PET or CT alone. Typically, a PET image is color coded—different colors show various levels of cell activity. A CT scan shows the exact locations of the body&#39;s organs and also can show abnormal growths. When a CT scan is laid over a PET scan, a clinician or doctor can pinpoint the exact location of the PET-detected activity (e.g., tumoral FDG metabolism). They can also see the level and extent of that activity. Even when an abnormal growth is not yet visible on a CT scan, the PET scan can show the abnormal cell activity.

     Therapeutic Methods, Formulations, Dosage and Administration 
     The present invention provides methods for PET imaging a tumor in a subject receiving and/or about to receive IGF1R inhibitor therapy. In an embodiment of the invention, the subject suffers from Ewing&#39;s sarcoma, e.g., recurrent or relapsed Ewing&#39;s sarcoma wherein the subject has failed to respond any further to frontline therapies. 
     The term “subject” or “patient” refers to a mammal such as a human (e.g., a human adult or child) or a mouse, rat, rabbit, dog or other canine, horse, goat or primate such as a monkey, chimpanzee or gorilla. 
     For example, the present invention includes a method for treating a Ewing&#39;s sarcoma tumor, in a subject, comprising evaluating glucose metabolism of the tumor after the subject has received a first dose of IGF1R inhibitor, but before a second dose of the inhibitor; or within about 14 days of a first dose of IGF1R inhibitor but before a second dose of said inhibitor; wherein treatment with the IGF1R inhibitor is discontinued if glucose metabolism does not significantly decrease or remain constant after said first dose; and continuing treatment with the IGF1R inhibitor if glucose metabolism does significantly decrease or remain constant after said first dose. Optionally, if the inhibitor does not exhibit sufficient efficacy, the dose can be increased, followed by a reevaluation of the tumor glucose metabolism relative the tumor glucose metabolism before the increased dose and, e.g., a determination as to whether to continue treatment, discontinue treatment or increase dosage as discussed above. 
     The present invention also includes a method for evaluating the effect of an IGF1R inhibitor on a Ewing&#39;s sarcoma tumor, in a subject, comprising evaluating glucose metabolism of the tumor after the subject has received a first dose of IGF1R inhibitor, but before a second dose of the inhibitor; or within 14 days of a first dose of IGF1R inhibitor but before a second dose of said inhibitor; wherein the inhibitor is determined not to exhibit sufficient efficacy against the tumor if glucose metabolism does not significantly decrease or remain constant after said first dose; and determining that the inhibitor does exhibit sufficient efficacy if glucose metabolism does significantly decrease or remain constant after said first dose. Optionally, if the inhibitor exhibits sufficient efficacy, treatment can be continued; or if the inhibitor does not exhibit sufficient efficacy, the treatment can be discontinued or the dose can be increased, followed by a reevaluation of the tumor glucose metabolism relative the tumor glucose metabolism before the increased dose, and, e.g., a determination as to whether to continue treatment, discontinue treatment or increase dosage as discussed above. 
     The IGF1R inhibitors discussed herein (e.g., anti-IGF1R antibodies and antigen-binding fragments thereof) and compositions thereof are, in an embodiment of the invention, administered at a therapeutically effective dosage. The term “therapeutically effective amount” or “therapeutically effective dosage” means that amount or dosage of an IGF1R inhibitor or composition thereof that will elicit a biological or medical response of a tissue, system, patient, subject or host that is being sought by the administrator (such as a researcher, doctor or veterinarian) which includes any measurable alleviation of the signs, symptoms and/or clinical indicia of a medical disorder, such as cancer (e.g., tumor growth and/or metastasis) including the prevention, slowing or halting of progression of the medical disorder to any degree whatsoever. For example, in one embodiment of the invention, a “therapeutically effective dosage” of any anti-IGF1R antibody or antigen-binding fragment thereof discussed herein (e.g., an anti-IGF1R antibody comprising mature LCC, LCD, LCE or LCF light chain and/or mature HCA or HCB heavy chain) is between about 0.3 and 20 mg/kg of body weight (e.g., about 0.3 mg/kg of body weight, about 0.6 mg/kg of body weight, about 0.9 mg/kg of body weight, about 1 mg/kg of body weight, about 2 mg/kg of body weight, about 3 mg/kg of body weight, about 4 mg/kg of body weight, about 5 mg/kg of body weight, about 6 mg/kg of body weight, about 7 mg/kg of body weight, about 8 mg/kg of body weight, about 9 mg/kg of body weight, about 10 mg/kg of body weight, about 11 mg/kg of body weight, about 12 mg/kg of body weight, about 13 mg/kg of body weight, about 14 mg/kg of body weight, about 15 mg/kg of body weight, about 16 mg/kg of body weight, about 17 mg/kg of body weight, about 18 mg/kg of body weight, about 19 mg/kg of body weight, about 20 mg/kg of body weight), e.g., about once per week to about once every 3 weeks (e.g., about once every 1 week or once every 2 weeks or once every 3 weeks). The therapeutically effective dosage of an IGF1R inhibitor or any further therapeutic agent is, when possible, as set forth in  Physicians Desk Reference  2010; Thomson Reuters; 64 edition (Nov. 15, 2009); and/or in  Physicians&#39; Desk Reference  2009; Thomson Reuters; 63rd edition (Nov. 30, 2008) or in the prescribing information of the relevant drug label (if available), such as the US FDA drug label.

     EXAMPLES 
     The present invention is intended to exemplify the present invention and not to be a limitation thereof. Method disclosed below fall within the scope of the present invention. Methods of the present invention may be modified by any one or more of the parameters set forth in the example below. 
     Example 1 
     Correlation of FDG-PET Signal to Anti-IGF1R Efficacy 
     The present study of FDG-PET signals in subjects receiving anti-IGF1R therapy is ongoing. These data represent that which is available at the time of filing. These data demonstrated that, when evaluated early in the treatment regimen (within 7-14 days of initial dose of anti-IGF1R), a decrease in  18 F-fluorodeoxyglucose metabolism, as measured via single FDG-PET scan, is a valuable predictor of antibody efficacy. 
     Seventy one subjects with Ewing&#39;s sarcoma (relapsed or recurrent) were enrolled on a clinical protocol for treatment with anti-IGF1R (comprising the light chain variable domain comprising amino acids 20-128 (linked to a kappa constant domain) and the heavy chain variable domain comprising amino acid 20-137 of SEQ ID NO: 10 (linked to a gamma-1 constant domain)). 66 were potentially evaluable, and some of these subjects were without PET scan data. Subjects have been followed for up to 30 weeks. In the Ewing&#39;s sarcoma group, 66 potentially evaluable patients have completed at least 4 doses (10 mg/kg every two weeks). Tumor regressions or tumor response to treatment have been observed and reported in at least 10 subjects in the form of partial responses. Stable disease has been observed in 4 or more subjects (decreasing or stable tumor burden but not sufficient for response). Of the responding subjects who had undergone PET scan evaluation after a single dose of anti-IGF1R, 4 out of 4 subjects had improvement in their PET signal after the single dose of anti-IGF1R. Three out of the 4 subjects had a &gt;25% improvement or decrease in the FDG-PET standardized uptake value, and the 4 th  subject had a 15% improvement. 
     Guidelines for Positron Emission Tomography (PET) and Positron Emission Tomography/Computed Tomography (PET/CT) 
     PET-FDG scans described and discussed herein were performed at various clinical sites that received the following operating guidelines. 
     All scans will be performed on a dedicated PET or PET/CT scanner (not a dual-headed SPECT scanner). The same PET or PET/CT scanner must be used for all exams for the same subject. Scanner requirements include:
         Field of View (FOV) appropriate for body imaging   High resolution and high sensitivity   Post injection transmission capability   Reconstruction algorithms with correction for attenuation, scatter and randoms   Ability to calculate Standardized Uptake Values (SUV)       

     Subject Preparation 
     
         
         
           
             Subjects should receive instruction to avoid strenuous exercise for 24 hours prior to a scheduled FDG-PET or FDG-PET/CT scan. 
             Subjects will need to fast (except water) for a minimum of 4 hours prior to radiotracer injection. 
             Subjects are encouraged to maintain well-hydrated status. 
             For all subjects, perform glucose monitoring (finger-stick glucose acceptable). If glucose &gt;150 mg/dl, reschedule exam with optimization of diabetic control. 
             Intravenous (IV) injection of radiotracer should be performed via a well functioning IV catheter. 
             The use of pre-medication to diminish activated brown fat activity may be used as per local site 
             Immediately before and after radiotracer injection, care should be taken to keep the subject warm and comfortable. The subject should sit or lie in a quiet area during the incubation phase. 
           
         
       
    
     Radiopharmaceutical 
     [ 18 ]-fluorodeoxyglucose, (FDG), a glucose analogue, is the only radiotracer that will be used in this study. FDG must be prepared in accordance with the institution&#39;s standard procedure or obtained from commercial vendor. The recommended dose of FDG is 10-20 mCi. 
     Scanning Protocol 
     
         
         
           
             Immediately prior to scanning, subjects should be asked to urinate to minimize the chance that they will need to move during the scan. 
             Baseline scans to be performed approximately 75 minutes (+/−10 minutes) following intravenous injection of radiotracer. The incubation time (time between radiotracer administration and start of emission scan) should be noted for the baseline exam. Follow-up scan incubation time should be within a +/−5-minute window of the baseline exam incubation time. 
             Scan the whole body to include the skull base to proximal femurs. Repeat sequence of anatomic acquisition (neck to pelvis or pelvis to neck) in standard fashion from time point to time point. 
             Acquisition time per bed position as per local site protocol, which should be duplicated at each time point. 
             Perform all scans with attenuation correction.
