Title A Multicenter, Randomized, Open-Label Phase 3 Study to Investigate the Efficacy and Safety of Aldoxorubicin Compared to Investigator’s Choice in Subjects with Metastatic, Locally Advanced, or Unresectable Soft Tissue Sarcomas Who Either Relapsed or Were Refractory to Prior Non-Adjuvant Chemotherapy

IRB CYT1714

CC 14-816

Hospital Main Campus

Phase Phase 3

Disease Sarcoma, Solid Tumors

Drug Aldoxorubicin

Description

Description

Primary Objective
  • To determine the efficacy of administration of aldoxorubicin compared to investigator's choice of treatment in subjects with metastatic, locally advanced, or unresectable soft tissue sarcomas who have relapsed or were refractory to prior non-adjuvant chemotherapy, as measured by PFS.
Secondary Objectives
  • To evaluate the efficacy of aldoxorubicin as measured by OS, safety of aldoxorubicin compared to investigator's choice in this population assessed by the frequency and severity of AEs, abnormal findings on physical examination, laboratory tests, vital signs, ECHO evaluations, ECG results, and weight, as well as disease control rate and tumor response.
Exploratory Objectives
  • To determine the PK of aldoxorubicin, doxorubicin, and doxorubicinol following IV administration of aldoxorubicin, and to evaluate the exposure-response relationships between aldoxorubicin, doxorubicin, and/or doxorubicinol and PFS, OS, and selected safety parameters, and quality of life.
Inclusion Criteria

Inclusion Criteria

  1. Has provided written informed consent prior to any study related activities.
  2. Age ≥15 years (US only), and 18-80 (ROW), male or female.
  3. Histological confirmation of intermediate or high grade soft-tissue sarcoma as determined by the local pathology report. Archival tissue must be sent to a central pathology lab for review but will not preclude entry onto the study (study-specific biopsies are not allowed). Final assessment of tumor grade and histology will be based on the designation provided by the central pathology review.
  4. An adequate tumor specimen obtained by either excisional biopsy, incisional biopsy or core needle biopsy must be sent to the central pathology lab for evaluation.
  5. Locally advanced, unresectable, and/or metastatic soft-tissue sarcoma of intermediate or high grade with evidence of disease progression by CT or MRI scan, or clinical judgment on or after the last cancer therapy within 6 months prior to randomization.
  6. Relapsed or refractory (lack of response) to ≥1 course of systemic chemotherapy regimen(s), excluding adjuvant or neoadjuvant chemotherapy and is incurable by either surgery or radiation.
  7. Capable of providing informed consent and complying with trial procedures.
  8. ECOG PS 0-2 (Appendix B).
  9. Life expectancy >12 weeks.
  10. Measurable tumor lesions according to RECIST 1.1 criteria.
  11. 11. Women must not be able to become pregnant (e.g., post-menopausal for at least 1 year, surgically sterile, or practicing adequate birth control methods) for the duration of the study. (Adequate contraception includes: oral contraception, implanted contraception, intrauterine device implanted for at least 3 months, or barrier method in conjunction with spermicide).
  12. Males and their female partner(s) of child-bearing potential must use 2 forms of effective contraception (see Inclusion 11 plus condom or vasectomy for males) from the last menstrual period of the female partner during the study treatment and agree to continue use for 6 months after the final dose of study treatment.
  13. Women of child bearing potential must have a negative serum or urine pregnancy test at the Screening Visit and be non-lactating.
  14. Accessibility to the site that optimizes the subject's ability to keep all study-related appointments.
Exclusion Criteria

Exclusion Criteria

  1. Prior exposure to >375 mg/m2 of either doxorubicin or liposomal doxorubicin.
  2. Palliative surgery and/or radiation treatment within 30 days prior to date of randomization.
  3. Exposure to any investigational agent within 30 days of date of randomization.
  4. Exposure to any systemic chemotherapy within 30 days of date of randomization.
  5. An inadequate tumor specimen as defined by the central pathologist.
  6. Current evidence/diagnosis of alveolar soft part sarcoma, extraskeletal myxoid chondrosarcoma, rhabdomyosarcoma, osteosarcoma, GIST, dermatofibrosarcoma (unless transformed to fibrosarcoma), Ewing's sarcoma, Kaposi's sarcoma, mixed mesodermal tumor, clear cell sarcomas.
  7. Evidence of CNS metastasis who have not received prior definitive therapy for their lesions.
  8. History of other malignancies except cured basal cell carcinoma, cutaneous squamous cell carcinoma, melanoma in situ, superficial bladder cancer or carcinoma in situ of the cervix unless documented free of cancer for ≥5 years.
  9. Laboratory values: Screening serum creatinine >1.5xULN, ALT >3xULN, or >5xULN if liver metastases are present, total bilirubin >2xULN, ANC <1,500/mm3, platelet concentration <100,000/mm3, hemoglobin <9 g/dL.
  10. Anion gap > 16 meq/L as determined by the Central Laboratory or arterial blood pH < 7.30, as determined by the Local Laboratory
  11. Clinically evident CHF > class II of the NYHA guidelines (Appendix D).
  12. Current serious, clinically significant cardiac arrhythmias, defined as the existence of an absolute arrhythmia or ventricular arrhythmias classified as Lown III, IV or V (Appendix F).
  13. Baseline QTc >470 msec and/or previous history of QT prolongation while taking other medications.
  14. Concomitant use of medications associated with a high incidence of QT prolongation is not allowed (Appendix G).
  15. History or signs of active coronary artery disease with or without angina pectoris within the last 6 months.
  16. Serious myocardial dysfunction defined by ECHO as absolute LVEF below the institution's lower limit of predicted normal.
  17. Known history of HIV infection.
  18. Active, clinically significant serious infection requiring treatment with antibiotics, anti-virals or anti-fungals. The Medical Monitor should be contacted for any uncertainties.
  19. Major surgery within 30 days prior to date of randomization.
  20. Current or past substance abuse or any condition that might interfere with the subject's participation in the study or in the evaluation of the study results.
  21. Any condition that is unstable and could jeopardize the subject's participation in the study.
