Anti-CD3 monoclonal antibodies induce the proliferation of human T-cells in vitro and activate specific and nonspecific cytolysis by human T-cell clones and human peripheral blood lymphocytes. In vivo administration of anti-CD3 prevents tumor growth of a UV-induced mouse fibrosarcoma. We conducted a phase I trial to determine the toxicity and immunomodulatory properties of low doses of anti-CD3 in 36 patients with cancer. In 23 patients, anti-CD3 was given i.v. over 3 h at 1, 10, 30, and 100 mcg/patient. Five other patients received anti-CD3 at 30 mcg by i.v. bolus. Patients were treated every 3 days for a total of four doses. An additional eight patients received anti-CD3 daily for 14 days at 3 mcg by i.v. bolus, 3-h infusion, or 24-h infusion. Dose-limiting toxicity was headache. Headache was often accompanied by signs and symptoms of meningeal irritation leading to performance of a lumbar puncture in nine patients. The opening pressure was usually elevated, and six patients had a cerebrospinal fluid lymphocytosis with an elevated protein. Increased levels of interleukin 6 were identified in the cerebrospinal fluid. The maximum tolerated dose by 3-h infusion was 30 mcg. There were no objective tumor responses. There was a dose-related increase in the number of peripheral blood lymphocytes expressing the T-cell activation antigen CD69 (Leu 23), but no changes were seen in CD25 (interleukin 2 receptor) expression, and no changes were observed in the serum levels of the soluble interleukin 2 receptor. Even at these low doses of anti-CD3, 8 of 16 patients tested developed human anti-mouse antibodies.

Tumor necrosis factor (TNF) is a cytokine with pleiotropic biological and antitumor effects in vitro and in mouse models. The immunological effects of the molecule as a single agent, however, have not been well studied clinically. We conducted a Phase I trial of TNF in 53 patients with advanced malignancies in order to determine the biological and clinical effects of TNF when administered as a 30-min i.v. infusion three times/week. Dose levels of TNF ranged from 5 to 275 micrograms/m2; doses of TNF were escalated between patient groups. The most common clinical toxicities of TNF consisted of rigors, anorexia, headache, and fatigue. Dose-limiting toxicity consisted of hypotension, fatigue, and nausea. Four patients treated at the maximally tolerated dose of 225 micrograms/m2 received dexamethasone to determine whether the toxicities of TNF could be ameliorated. No significant differences in hypotension or subjective symptomatology were observed in those patients receiving dexamethasone and those who did not or between injections in which dexamethasone was administered and when it was not. One patient with colorectal carcinoma treated with 50 micrograms/m2 had a partial response lasting about 9 months. Biological responses were evaluated in 8 patients treated at the maximally tolerated dose before therapy and 24 h afterward. TNF significantly (P less than 0.05 for all) enhanced serum beta 2-microglobulin, serum neopterin, and serum interleukin-2 receptor (Tac antigen) levels. Indoleamine 2,3-dioxygenase activity was also increased 24 h following the administration of TNF, although this increase was only of borderline statistical significance (P = 0.07). TNF did not enhance granulocyte bactericidal activity. The expression of cell surface proteins on monocytes, including HLA-DR, HLA-DQ, beta 2-microglobulin, and the Fc receptor, and serum interleukin-1 activity also were not significantly increased by the administration of TNF. Thus, in humans TNF caused biological response modulation with evidence of HLA Class I (beta 2-microglobulin) increase and T-cell (Tac antigen) and monocyte (neopterin) activation.

Thirteen patients with DSM-III-R diagnosis of either major depression or bipolar I depression participated in the study. The control group consisted of 10 subjects evaluated for headache or suspected meningitis, none of whom were found to suffer from any organic disease. CSF was withdrawn from all subjects for the measurement of soluble interleukin 2 receptor (sIL-2R). CSF sIL-2R levels were found to be lower in patients as compared to controls (df = 1, 20; F = 84; p<0.000001).
