Phase II Trial of High Dose Interleukin-2 Followed by Intermittent Low Dose Temozolomide in Patients With Metastatic Malignant Melanoma

Detailed Summary

The investigators have observed that many patients who had received high dose Interleukin-2 (IL2) and failed to respond to it but who then go immediately to temozolomide seemed to enjoy extremely good responses which seem better quality and longer duration than typically observed for temozolomide alone. To date, the investigators have observed 5 sequentially treated patients with metastatic melanoma who had failed high dose IL-2 but who then went on to receive immediate temozolomide. Two of these patients had complete responses and 3 had very strong partial response. In a recent phase II study of extended low dose temozolomide alone given in the same manner as the post IL-2 patients noted above, the response rate was 12.5% and all of these were partial responses only. The responses that the investigators observed were at a much higher rate of response as well as much better quality than expected for temozolomide. The responses were also better than those observed when temozolomide was given first and then followed by high dose IL-2. The investigators concluded that perhaps the major benefit the investigators observed was a result of the prior high dose IL-2 therapy modulated by the temozolomide and that the sequence of treatment was clearly crucial for this response.
