Antineoplastons (PDQ®): Complementary and alternative medicine - Health Professional Information [NCI] - Human / Clinical Studies

continued...

In addition to antineoplaston AS2-5 injections, two patients also received injections of antineoplaston AS2-1, and one patient received antineoplaston A10 after surgical intervention for a recurrence. Patients received other drugs such as antibiotics, analgesics, anti-inflammatory agents, anti-emetics, bronchial dilators, diuretics, corticosteroids, antihistamines, and uricosuric agents.

Side effects included chills and fever in two patients; swelling of the joints, bone pain, and redness of hands and feet in one patient; increase in platelet count in one patient; and an increase in plasma globulin in one patient.

Two patients were classified as having achieved complete remission, four patients were classified as having stable disease, six had disease progression, and one patient had a mixed response. During the study, eight patients discontinued treatment and were lost to follow-up, and three patients died. At the time of study publication, one patient who was given A10 after surgical intervention for recurrence was reported to be free of cancer for a period of slightly more than 4 years.[5]

Antineoplaston A2

In a 1987 study, 15 patients received antineoplaston A2 through intravenous subclavian catheter. Minor side effects were noted in four patients: fever, chills, and muscle pain. Of the 15 patients, 9 had objective response to treatment: complete tumor response in 7 and partial tumor response in 2. Five patients had stable disease, and one had disease progression. Follow-up showed three patients with complete response were cancer-free 5 years after treatment, and three patients were known to have survived for 4 years from the beginning of the study. Three patients were followed for 2 years, at which time they discontinued AS2-1 therapy. Five patients died within 2 years of the start of the study, and one patient was lost to follow-up.[6]

Antineoplaston A3

In 1987, 24 patients with 25 various malignancies participated in a retrospective nonconsecutive case series study of antineoplaston A3. Patients who had more than 6 weeks' anticipated survival and who continued the treatment for more than 6 weeks were eligible. Antineoplaston A3 was administered through subclavian vein catheter in 23 patients. One patient received IM injections. Length of treatment was 44 to 478 days. Side effects, which occurred only once during treatment, included fever and chills in four patients, vertigo in two patients, headache in two patients, flushing of the face in one patient, nausea in one patient, and tachycardia in one patient. In addition, there was an increase in platelets, white blood cell counts, and reticulocyte counts. Tumor response was complete in five patients, and partial response was seen in five patients. Stable disease was reported in nine patients, while six patients had disease progression. One patient received radiation therapy before entering the study, so tumor response cannot be attributed solely to A3. Six patients discontinued treatment during the study; no reasons were reported.[7]
