AVAX reports positive interim results in M-Vax study

March 15, 2000 07:05 PM Eastern Time
KANSAS CITY, Mo., March 15 (Reuters) - AVAX Technologies Inc. AVXT said on Wednesday it received positive interim results from a low-dose Phase 2 study of M-Vax, a therapeutic cancer vaccine for post-surgical, stage III metastatic melanoma made by modifying a patient's own tumor cells with a molecule called a "hapten."

The purpose of the ongoing study is to evaluate M-Vax's ability to stimulate an immune response against a patient's own tumor cells utilizing a lower vaccine dose than previously tested.

Lowering the vaccine dose reduces the amount of tumor tissue required for manufacturing and thereby expands the number of eligible patients, AVAX said in a news release.

Preliminary results from 23 patients demonstrated that 65 percent of them responded favorably to the lower dose, as measured by a delayed type hypersensitivity test (DTH), a skin test that measures a patient's immune response against the patient's own tumor cells.

The data obtained from this study to date show the same magnitude of positive immunological responses as seen after higher dose M-Vax treatment in earlier studies, the company said.

Results in these earlier studies indicated a strong correlation between positive clinical outcomes and M-Vax's ability to induce an immunological response against a patient's own tumor cells.

Follow-up of over 350 patients to date continues to support this correlation
