Clinical Trial of Vincristine vs. Prednisolone for Treatment of Complicated Hemangiomas
|Study Design:||Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||A Phase II, Randomized, Clinical Trial Assessing Efficacy And Safety Of Oral Prednisolone vs Intravenous Vincristine In The Treatment Of Infantile|
- Response of Hemangioma (IH) to Treatment [ Time Frame: 6 weeks ] [ Designated as safety issue: Yes ]
Response of IH not confined to the dermis will be coded using the following criteria: Progressive disease: >40% increase in volume by MRI, Partial response: >65% reduction in volume by MRI, Complete response: no visual or radiographic evidence of disease, Stable disease: none of the above or <40% increase or <65% decrease in volume by MRI.
Response of superficial IH will be coded using the following criteria (based on RECIST): Progressive disease: >30% increase in IH size, Partial response: >30% reduction in size, Complete response: no evidence of disease, Stable disease: none of the above.
Our first 3 patients showed limits to using MRI volume to measure IH size/response to therapy. Unlike other solid tumors, the superficial distribution of some IH made getting volume by MRI difficult, resulting in smaller tumor estimation compared to clinical assessment. Based on these observations, we amended the protocol to report response based on RECIST criteria instead of change in IH volume.
- Toxicity to Medications [ Time Frame: Initial visit, 2, 4, 6, 10 and 12 weeks of therapy ] [ Designated as safety issue: Yes ]
Adverse events were closely monitored and recorded at weekly visits during treatment period and for two years after treatment ceased. Laboratory values were taken every other week during the treatment period.
Please see Adverse Events module for more details.

Vincristine is a drug that has been used to treat cancers in children (including infants). It has been effective in treating a small number of infants with hemangiomas, most of whom failed previous therapies including steroids. Vincristine must be administered into a vein. Given the encouraging response data and documented safety record, Vincristine is a good choice for a clinical trial treating infants with complicated hemangiomas.
Vincristine (0.05 mg/kg/dose) will be administered into a vein (PICC line) every week for 12 weeks. If assigned to receive Vincristine, a PICC line will be placed by a doctor who is a specialist in this procedure, an interventional radiologist. This will require sedation and when possible, will be coordinated with sedation for the MRI.
Other Name: VINCRISTINE SULFATE (Oncovin®, VCR, LCR) NSC #67574 (042006)
Active Comparator: 2
The standard treatment for hemangioma at most centers is oral steroids (Prednisolone). Prednisolone has been used to stop the growth of infantile hemangiomas that are life threatening, that could harm important functions, or are likely to result in severe disfigurement (scarring) without treatment.
Prednisolone given at 3 mg/kg/day by mouth for 12 week
Other Name: PREDNISOLONE SODIUM PHOSPHATE SYRUP/SOLUTION 15mg/5 cc (Orapred®)
