Exclusion Criteria:
Arm A (advanced solid tumors)
1. Systemic anti-cancer treatment (investigational or approved) within 28 days or 5 half-lives of that drug (whichever is shorter) of the first dose of NBM-BMX.
2. Curative radiation therapy within 28 days or palliative RT within 7 days of the first dose of NBM-BMX.
3. Currently taking strong inhibitors (e.g., gemfibrozil) or inducers of CYP2C8.
4. Any of the following within 6 months of the first dose of NBM-BMX: pulmonary embolism events, deep vein thrombosis (DVT) events, myocardial infarction, severe/unstable angina, coronary/peripheral artery bypass graft, congestive heart failure, or cerebrovascular accident including transient ischemic attack.
5. A positive test for hepatitis B (HBsAg) and/or hepatitis C (anti-HCV antibody), unless the HBV DNA level and/or HCV RNA level is below the limit of detection.
6. Known history of human immunodeficiency virus (HIV) infection.
7. Men and women of childbearing potential who are unwilling to use highly effective contraceptive methods during the study period.
Highly effective contraceptive methods include implants, injectables, combined oral contraceptives, intra-uterine devices (IUDs), sexual abstinence, surgical sterilization or a partner who is sterile.
8. Females who are pregnant or breastfeeding.
9. Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that would impart, in the judgement of the investigator and/or sponsor, excess risks associated with study participation or study drug administration.
Arm B (newly diagnosed GBM)
1. Prior systemic therapy (including Gliadel wafer implant), immunotherapy, investigational agents, or radiotherapy for glioblastoma.
2. Currently taking strong inhibitors (e.g., gemfibrozil) or inducers of CYP2C8.
3. Corticosteroid use of \> 8 mg/day dexamethasone or equivalent within 5 days before the first dose of NBM-BMX.
4. A history of hypersensitivity reaction to temozolomide or dacarbazine.
5. Any of the following within 6 months of the first dose of NBM-BMX: pulmonary embolism events, deep vein thrombosis (DVT) events, myocardial infarction, severe/unstable angina, coronary/peripheral artery bypass graft, congestive heart failure, or cerebrovascular accident including transient ischemic attack.
6. A positive test for hepatitis B (HBsAg) and/or hepatitis C (anti-HCV antibody), unless the HBV DNA level and/or HCV RNA level is below the limit of detection.
7. Known history of human immunodeficiency virus (HIV) infection. Note: HIV testing is not required.
8. Men and women of childbearing potential who are unwilling to use highly effective contraceptive methods during the study period and for at least 6 months after the final dose of temozolomide.
Highly effective contraceptive methods include implants, injectables, combined oral contraceptives, intra-uterine devices (IUDs), sexual abstinence, surgical sterilization or a partner who is sterile.
9. Female who are pregnant or breastfeeding.
10. Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that would impart, in the judgement of the investigator and/or sponsor, excess risks associated with study participation or study drug administration.
