Prospective Clinical Trial Evaluating Metronomic Chemotherapy in Patients With High-grade, Operable, Non-metastatic Osteosarcoma of the Extremity

February 10, 2016 updated by: Antônio Sérgio Petrilli, Grupo de Apoio ao Adolescente e a Crianca com Cancer
Preclinical models show that a daily antiangiogenic regimen at low-dose may be effective against chemotherapy-resistant tumors. The aim of this study is to evaluate the efficacy of maintenance therapy with continuous oral cyclophosphamide and methotrexate in patients with high grade, operable, non-metastatic osteosarcoma (OST) of the extremities. The primary end point is event-free survival (EFS) from randomization.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study design includes a backbone of 10 weeks of preoperative therapy using MAP (High-dose methotrexate, cisplatin, and doxorubicin). Following surgery, non-metastatic patients were randomized by blocks to complete 31 weeks of MAP or to receive 73 weeks of maintenance therapy following MAP; while metastatic patients received maintenance therapy in combination with MAP since the beginning of treatment.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 day to 30 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Patients with high-grade malignancy osteosarcoma , biopsy-proven , newly diagnosed , previously untreated . Patients with osteosarcoma as a second malignancy should also be eligible .
  2. Patients with any primary site , with or without metastases at diagnosis , will be accepted and treated.
  3. Patients < 30 years.
  4. Patients must have normal body function and adequate renal function defined as serum creatinine < 1.5 x the normal value or creatinine clearance > 60ml/min/1 ,73m2 .
  5. Patients must have adequate hepatic function, defined as total bilirubin < 1.5 x normal, aspartate aminotransferase (AST or SGOT) and alanine aminotransferase (ALT or SGPT) < 2.5 x normal.
  6. Patients must have adequate cardiac function defined by a shortening fraction > 27 % by echocardiogram or ejection fraction > 47 % by radioisotopic angiogram .

  7. If pre- chemotherapy amputation is necessary, the patient is included in the study and eligible to survival analyzes, however the pathological analyze response will be not performed.

    Obtain material for pathological and molecular study is recommended .

  8. Whenever possible a central catheter should be placed against the intensity of chemotherapy and need for forced hydration .
  9. Patient or legal guardian must sign a consent form which will be explain the type of treatment and procedures that the patient will be submitted .

Exclusion Criteria:

  1. Disease progression ( increase of at least 20% of the extent of the lesion, taking as reference the smallest measurement recorded from the start of treatment, or the appearance of one or more lesions );
  2. Any properly documented clinical situation , which at the discretion of the attending physician , patient can not follow with chemotherapy , for safety reasons ;
  3. The evaluation of cardiac aspects will be done carefully , so will exclude patients with 20% reduction in the ejection fraction of the left ventricle compared to baseline or with a ventricular ejection fraction < 45 % regardless of baseline;
  4. The patient refusal to continue treatment ;
  5. Nephrotoxicity , neurotoxicity and ototoxicity grade 4 ;
  6. Delay greater than 40 days for the realization of the next treatment cycle , not related to toxicity;
  7. Refusal of surgery ; 8 . Variation above 20% of the recommended dose without justification.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
