Brief Summary:
This is a phase 1/2 study evaluating safety, tolerability, and efficacy of lenvatinib as single-agent, and in combination with chemotherapy (ifosfamide and etoposide) in children and adolescents with refractory or relapsed solid malignancies including differentiated thyroid carcinoma (single agent lenvatinib) and osteosarcoma (single agent and combination lenvatinib).

Condition or disease Intervention/treatment Phase
Tumors Solid Malignant Tumors Osteosarcoma Differentiated Thyroid Cancer (DTC) Drug: Lenvatinib Drug: Ifosfamide Drug: Etoposide Phase 1 Phase 2

Detailed Description:

The study consists of 5 cohorts:

Cohort 1 (Single-Agent Dose-Finding) dose-escalation to find the recommended dose (RD) of lenvatinib using time-to-event continual reassessment method (TiTE-CRM) in children and adolescents with relapsed or refractory solid malignant tumors. When the RD is identified, Cohorts 2A, 2B, and 3A will enroll in parallel.

Cohort 2 (Single-Agent Expansion) will evaluate the efficacy of lenvatinib at the RD in children, adolescents, and young adults with

  1. 131 iodine-refractory differentiated thyroid cancer (DTC) [Cohort 2A] or
  2. Relapsed or refractory osteosarcoma [Cohort 2B]

Cohort 3A (Combination Dose-Finding) will determine the RD of lenvatinib in combination with ifosfamide and etoposide in children, adolescents, and young adults with relapsed or refractory osteosarcoma.

Cohort 3B (Combination Expansion) will evaluate the efficacy of lenvatinib at the RD from Cohort 3A in combination with ifosfamide and etoposide in children, adolescents, and young adults with relapsed or refractory osteosarcoma. Participants with osteosarcoma who have enrolled into Cohort 1 or 2B and experienced progressive disease will also be candidates for enrollment in Cohort 3B.

Lenvatinib will be provided as hard capsules containing 1, 4, or 10 mg lenvatinib. Lenvatinib capsules should be dissolved in water or apple juice for those who are unable to swallow capsules.

PD: >= 20% increase in sum of diameters of target lesions, reference-smallest sum recorded in study (sum at baseline if that was smallest). Sum of diameters must have absolute increase of >=5 mm. Appearance of >=1 new lesions also considered PD.

    In acceptability questionnaire, participants were asked to answer the overall acceptability of lenvatinib suspension considering the following elements: taste, appearance, smell and how does it feel in the mouth. Overall acceptability was answered in terms of 7 responses: Super good, really good, good, may be good or may be bad, bad, really bad, super bad. Overall acceptability was the overall acceptance for taste, appearance, smell, and the feeling in mouth. In this measure, number of participants have been reported per their overall acceptability responses.

    b) Urine dipstick less than 2+ for proteinuria. Participants who have greater than or equal to 2+ proteinuria on dipstick urinalysis should undergo a spot protein-creatinine (P/C) ratio that should be Grade less than 2.

    c) No clinical evidence of nephrotic syndrome.

  13. Adequate cardiac function as evidenced by left ventricular ejection fraction (LVEF) greater than or equal to 50%) at baseline as determined by echocardiography.
  14. Adequately controlled blood pressure (BP) with or without antihypertensive medications, defined as:

    BP less than 95th percentile for sex, age, and height/length at screening (as per National Heart Lung and Blood Institute guidelines) and no change in antihypertensive medications within 1-week prior to Cycle 1/Day 1. Osteosarcoma subjects 18 to 25 years should have BP ≤150/90 mm Hg at screening and no change in antihypertensive therapy within 1 week prior to Cycle 1/Day 1.

  15. Washout of 3 weeks in case of prior chemotherapy, 6 weeks if treatment included nitrosoureas; 4 weeks for definitive radiotherapy, and 2 weeks for palliative radiotherapy; 3 months from high-dose chemotherapy and stem cell rescue; 3 weeks from major surgery. Participants must have recovered from the acute toxic effects of all prior anticancer therapy before enrollment into the study.
  16. Written and signed informed consent from the parent(s) or legal representative (guardian) and assent from the minor participant. Written informed consent from subjects ≥18 years.
  17. Willing and able to comply with the protocol, scheduled follow-up, and management of toxicity as judged by the Investigator.

    Cohort 3B (Combination Expansion): Osteosarcoma subjects who progressed in Cohorts 1 or 2B and opt to receive combination therapy.

  18. Osteosarcoma participants receiving combination therapy of lenvatinib with ifosfamide and etoposide should meet only Inclusion Criteria Numbers 6 through 17 (after progression in Cohort 2B).

Exclusion criteria:

  1. Any active infection or infectious illness unless fully recovered prior to dosing.
  2. Any medical or other condition that in the opinion of the investigator(s) would preclude the participant's participation in a clinical study.
  3. Other organ toxicity due to prior anticancer therapy (investigational agent, chemotherapy, or radiation therapy) except alopecia, and ototoxicity due to cisplatin not already covered in the inclusion/exclusion criteria, which has not recovered to Grade less than 2 per Common Terminology Criteria for Adverse Events (CTCAE) v4.0.
  4. Known hypersensitivity to any component of the product (lenvatinib or ingredients).
  5. Concurrent administration of any other antitumor therapy.
  6. Previous treatment with lenvatinib (except for participants previously enrolled into Cohorts 1 or 2B of this study).
  7. Two or more prior vascular endothelial growth factor/vascular endothelial growth factor receptor (VEGF/VEGFR) targeted therapies.
  8. Currently receiving any investigational drug or device in another clinical trial or within 30 days preceding informed consent.
  9. A clinically significant ECG abnormality, including a marked baseline prolonged QT or QTc interval (eg, a repeated demonstration of a QTc interval greater than 480 msec).
  10. Gastrointestinal malabsorption or any other condition that in the opinion of the investigator might affect the absorption of lenvatinib.
  11. Gastrointestinal bleeding or active hemoptysis (bright red blood of at least half teaspoon) within 3 weeks prior to the first dose of study drug.
  12. Active second malignancy within 2 years prior to enrollment ([in addition to the primary tumor types specified by cohort in Inclusion Criterion Number 1], but not including definitively treated superficial melanoma, in-situ, basal or squamous cell carcinoma of the skin).
  13. Previous treatment with ifosfamide and Grade greater than or equal to 3 nephrotoxicity or encephalopathy (Cohorts 3A and 3B).
  14. Females who are breastfeeding or pregnant at Screening or Baseline (as documented by a positive beta-human chorionic gonadotropin [ß-hCG] (or human chorionic gonadotropin [hCG]) test with a minimum sensitivity of 25 IU/L or equivalent units of ß-hCG [or hCG]). A separate baseline assessment is required if a negative screening pregnancy test was obtained more than 72 hours before the first dose of study drug.

    Cohort 3B (Combination Expansion): Osteosarcoma participants who progressed in Cohorts 1 or 2B and opt to receive combination therapy.

  15. Osteosarcoma participants receiving combination therapy of lenvatinib with ifosfamide and etoposide should meet all the exclusion criteria, with the exception of Criterion Number 6.
