&#xD;
          3. Patients must have written documentation of IDH1 mutation at the R132 locus by&#xD;
             immunohistochemistry or DNA sequencing in their tumor.&#xD;
&#xD;
          4. Histopathological diagnosis of a glioma of WHO grade II or III at initial diagnosis.&#xD;
             Documentation of diagnosis by pathology report is sufficient for eligibility.&#xD;
&#xD;
          5. First line management with observation alone or external beam radiation after surgery.&#xD;
             Notes or records from the treating oncologist or radiation oncologist are required for&#xD;
             documentation of treatment history.&#xD;
&#xD;
          6. Patients must have unequivocal progression on brain MRI after observation or external&#xD;
             beam radiation. If a patient was initially diagnosed with a non-enhancing tumor and&#xD;
             the tumor develops new contrast-enhancement at progression, they will be excluded&#xD;
             except for the following exceptions:&#xD;
&#xD;
               1. Patients with tumors that were contrast-enhancing at initial diagnosis of grade&#xD;
                  II or III glioma will be allowed if their tumors are contrast-enhancing at&#xD;
                  progression as well.&#xD;
&#xD;
               2. If a patient with a grade II or III glioma has a tumor that develops new&#xD;
                  contrast-enhancement at progression, the enhancing portion of the progressive&#xD;
                  tumor must be biopsy proven WHO grade II or III at progression.&#xD;
&#xD;
          7. Measurable tumor of at least 1 cm x 1 cm in diameter by MRI. The measurable tumor may&#xD;
             be contrast-enhancing or non-enhancing.&#xD;
&#xD;
          8. Interval of at least 12 weeks from the completion of any prior radiotherapy and&#xD;
             registration. If patients have not passed an interval of at least 12 weeks, they may&#xD;
             still be eligible if they meet one or more of the following criteria:&#xD;
&#xD;
               1. New areas of tumor outside the original radiotherapy fields as determined by the&#xD;
                  investigator, or&#xD;
&#xD;
               2. Histologic confirmation of tumor (as opposed to pseudo-progression or radiation&#xD;
                  necrosis) through biopsy or resection&#xD;
&#xD;
          9. Collection of an archival tumor block with a minimum of 1 cm2 surface area of viable&#xD;
             tumor or at least 20 unstained 5 micron slides from the most recent surgery.&#xD;
&#xD;

&#xD;
         11. An interval of at least 2 weeks (to start of study agent) between prior surgical&#xD;
             resection of glioma, or one week for stereotactic biopsy of glioma.&#xD;
&#xD;
         12. Adequate hematologic, hepatic, and renal function defined by absolute neutrophil count&#xD;
             ≥1.0 x 109/L, hemoglobin ≥8 g/dL, platelet count ≥ 75 x 109/L (may have been&#xD;
             transfused), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤3 x&#xD;
             upper limit of normal (ULN), total bilirubin &gt; 1 x ULN, and serum creatinine &gt;1.5 x&#xD;
             ULN&#xD;
&#xD;
        Exclusion Criteria:&#xD;
&#xD;

&#xD;
          3. Unable to tolerate a contrast-enhanced brain MRI or if MRI is contraindicated&#xD;
&#xD;
          4. Two weeks since any major surgery treatment (mediastinoscopy, insertion of a central&#xD;
             venous access device and insertion of a feeding tube are not considered major surgery)&#xD;
             prior to registration, with the exception of stereotactic biopsy for glioma, in which&#xD;
             case an interval of 1 week until registration is allowed.&#xD;
&#xD;
          5. Patients who are currently receiving treatment with a prohibited medication or herbal&#xD;
             remedy that cannot be discontinued at least one week prior to the start of treatment.&#xD;

&#xD;
               3. Other herbal preparations and supplements&#xD;
&#xD;
               4. Inhibitors of UGT1A1&#xD;
&#xD;
          6. Prior exposure to a therapy targeting IDH1, including targeted inhibitors of IDH1 and&#xD;

             cyclophosphamide, etoposide, etc. Chemotherapy is associated with hypermutation&#xD;
             phenotype at recurrence and therefore patients who have had prior treatment with these&#xD;
             agents are excluded.&#xD;
&#xD;
          8. Rapidly progressing neurological symptoms related to underlying disease requiring&#xD;
             increasing doses of corticosteroids. Steroid use for management of gliomas is allowed&#xD;
             but the dose must be stable for at least 1 week preceding the baseline MRI/CT. If the&#xD;
             corticosteroid dose is increased between the date of imaging and the initiation of&#xD;
             study treatment, a new baseline MRI is required.&#xD;
&#xD;
          9. Malignant disease, other than that being treated in this study. Exceptions to this&#xD;
             exclusion include the following: malignancies that were treated curatively and have&#xD;
             not recurred within the prior 2 years from the time of registration; completely&#xD;
             resected basal cell and squamous cell skin cancers; any malignancy considered to be&#xD;
             indolent and that has never required therapy; and completely resected carcinoma in&#xD;
             situ of any type.&#xD;

             clinically significant, uncontrolled heart disease, including acute myocardial&#xD;
             infarction or unstable angina &lt; 3 months prior to the first dose of IDH305.&#xD;
&#xD;
         11. Any other medical condition that would, in the investigator's judgment, prevent the&#xD;
             patient's participation in the clinical study due to safety concerns or compliance&#xD;
             with clinical study procedures such as the presence of other clinically significant&#xD;
             cardiac, respiratory, gastrointestinal, renal, hepatic, infectious, psychiatric or&#xD;
             neurological disease.&#xD;
&#xD;
         12. Patients with Gilbert's syndrome or other heritable diseases of bile processing.&#xD;
&#xD;
         13. Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a&#xD;
             female after conception and until the termination of gestation, confirmed by a&#xD;
             positive hCG laboratory test.&#xD;
&#xD;
         14. Women of child-bearing potential (WOCBP), defined as all women physiologically capable&#xD;
             of becoming pregnant, unless they are using highly effective methods of contraception&#xD;
             during dosing and for 30 days after the use of the investigational medication. Highly&#xD;
             effective contraception methods include:&#xD;
&#xD;
               -  Total abstinence (when this is in line with the preferred and usual lifestyle of&#xD;
                  the patient). Periodic abstinence (e.g., calendar, ovulation, post-ovulation&#xD;
                  methods) and withdrawal are not acceptable methods of contraception&#xD;
&#xD;
               -  Female sterilization (have had surgical bilateral oophorectomy with or without&#xD;
                  hysterectomy), total hysterectomy, or tubal ligation at least six weeks before&#xD;
                  taking study treatment. In case of oophorectomy alone, only when the reproductive&#xD;
                  status of the woman has been confirmed by follow up hormone level assessment&#xD;
&#xD;
               -  Male sterilization (at least 6 months prior to screening). The vasectomized male&#xD;
                  partner should be the sole partner for that patient&#xD;
&#xD;
               -  Combination of any two of the following (a+b, a+c, or b+c):&#xD;
&#xD;
                    1. Use of oral, injected or implanted hormonal methods of contraception or&#xD;
                       other forms of hormonal, for example hormone vaginal ring or transdermal&#xD;
                       hormone contraception.&#xD;
&#xD;
                         -  In case of use of oral contraception women should have been stable on&#xD;
                            the same pill for a minimum of 3 months before taking study treatment.&#xD;
&#xD;
                    2. Placement of an intrauterine device (IUD) or intrauterine system (IUS)&#xD;
&#xD;
                    3. Barrier methods of contraception: condom or occlusive cap (diaphragm or&#xD;
                       cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal&#xD;
                       suppository&#xD;
&#xD;
         15. Women are considered post-menopausal and not of child bearing potential if they have&#xD;
             had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile&#xD;
             (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral&#xD;
             oophorectomy (with or without hysterectomy), total hysterectomy or tubal ligation at&#xD;
             least six weeks prior to screening. In the case of oophorectomy alone, only when the&#xD;
             reproductive status of the woman has been confirmed by follow up hormone level&#xD;
             assessment is she considered not of child bearing potential.&#xD;
&#xD;
         16. Sexually active males must use a condom during intercourse while taking the drug and&#xD;
             for 30 days after stopping treatment and should not father a child in this period. A&#xD;
             condom is required to be used also by vasectomized men as well as during intercourse&#xD;
             with a male partner in order to prevent delivery of the drug via semen.&#xD;
