E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria | 1. Age: At time of study enrollment, patients must be a. Part 1 (including PK expansion cohort): from birth to <18 years of age; b. Part 2: from birth to <18 years of age (except as noted below); Note: Patients <2 years of age will only be enrolled in Europe, however, enrollment of patients <2 years of age will not begin until definitive juvenile animal toxicity data is available. 2. Diagnosis a. Part 1 – Patients with any recurrent or refractory solid tumors or lymphoma (not CNS) that have a known or expected dysfunction of VEGFR-1, -2, and -3; FGFR-1, or CSF-1R pathways (based on literature) are eligible. Patients must have had histologic verification of malignancy at original diagnosis or relapse. b. Part 2 – Recurrent or refractory osteosarcoma, Ewing sarcoma, RMS, or NRSTS (EU/UK only). Patients must have had histologic verification of malignancy at original diagnosis or relapse. 3. Disease status: Patients must have measureable or evaluable disease for part 1 dose escalation; for part 2, patients must have measurable disease by RECIST version 1.1. 4. Therapeutic options: Patient’s current disease state must be one for which there is no known curative therapy. 5. Performance level: Karnofsky ≥50 for patients ≥16 and <18 years of age and Lansky ≥50 for patients <16 years of age (see Appendix 1 of the study protocol), Eastern Cooperative Oncology Group (ECOG) ≤2 for patients ≥18 years of age. (Note: Patients who are unable to walk because of paralysis, but who are using a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.) For further details regarding inclusion criteria please refer to the study protocol. | |
E.4 | Principal exclusion criteria | 1. Pregnancy or breastfeeding: Pregnant or breastfeeding females will not be entered into this study due to risks of fetal and teratogenic AEs as seen in animal toxicity studies. Pregnancy tests must be obtained in females who are postmenarchal. 2. Concomitant medications a. Corticosteroids: patients receiving corticosteroids who have not been on a stable or decreasing dose of corticosteroid for at least 7 days prior to enrollment are not eligible (if used to modify immune AEs related to prior therapy, ≥14 days must have elapsed since last dose of corticosteroid). b. Investigational drugs: patients who are currently receiving another investigational drug are not eligible. c. Anticancer agents: patients who are currently receiving other anticancer agents are not eligible. d. QTc agents: patients who are receiving drugs that prolong QTc within the last 7 days are not eligible. e. Patients may not be on clozapine, natalizumab, leflunomide, tofacitinib, or warfarin as these may interact with gemcitabine. f. Patients who are receiving medications that are strong inhibitors or inducers of CYP3A4 3. Thyroid replacement therapy: Patients who require thyroid replacement therapy are not eligible if they have not been receiving a stable replacement dose for at least 3 weeks prior to study enrollment. 4. Patients who have uncontrolled infection are not eligible. 5. Patients who have major surgery or significant traumatic injury within 28 days of the first dose of study treatment are not eligible. a. Central line placement or subcutaneous port placement is not considered major surgery. External central lines must be placed at least 3 days prior to enrollment and subcutaneous ports must be placed at least 7 days prior to enrollment. For further details regarding exclusion criteria please refer to the study protocol. | |
