2B1 is a bispecific murine monoclonal antibody (BsMAb) with specificity for the c-erbB-2 and Fc gamma RIII extracellular domains. This BsMAb promotes the targeted lysis of malignant cells overexpressing the c-erbB-2 gene product of the HER2/neu proto-oncogene by human natural killer cells and mononuclear phagocytes expressing the Fc gamma RIII A isoform. In a Phase I clinical trial of 2B1, 15 patients with c-erbB-2-overexpressing tumors were treated with 1 h i.v. infusions of 2B1 on days 1, 4, 5, 6, 7, and 8 of a single course of treatment. Three patients were treated with daily doses of 1.0 mg/m2, while six patients each were treated with 2.5 mg/m2 and 5.0 mg/m2, respectively. The principal non-dose-limiting transient toxicities were fevers, rigors, nausea, vomiting, and leukopenia. Thrombocytopenia was dose limiting at the 5.0 mg/m2 dose level in two patients who had received extensive prior myelosuppressive chemotherapy. Murine antibody was detectable in serum following 2B1 administration, and its bispecific binding properties were retained. The pharmacokinetics of this murine antibody were variable and best described by nonlinear kinetics with an average t 1/2 of 20 h. Murine antibody bound extensively to all neutrophils and to a proportion of monocytes and lymphocytes. The initial 2B1 treatment induced more than 100-fold increases in circulating levels of tumor necrosis factor-alpha, interleukin 6, and interleukin 8 and lesser rises in granulocyte-monocyte colony-stimulating factor and IFN-gamma. Brisk human anti-mouse antibody responses were induced in 14 of 15 patients. Several minor clinical responses were observed, with reductions in the thickness of chest wall disease in one patient with disseminated breast cancer. Resolution of pleural effusions and ascites, respectively, were noted in two patients with metastatic colon cancer, and one of two liver metastases resolved in a patient with metastatic colon cancer. Treatment with 2B1 BsMAb has potent immunological consequences. The maximum tolerated dose and Phase II daily dose for patients with extensive prior myelosuppressive chemotherapy was 2.5 mg/m2. Continued dose escalation is required to identify the maximally tolerated dose for patients who have been less heavily pretreated.

A phase II trial investigating the anti-tumour effects of recombinant human interleukin 6 (rhIL-6) in patients with metastatic renal cell cancer was carried out. RhIL-6 (150 microgram) was administered as a daily subcutaneous injection for 42 consecutive days on an outpatient basis. Forty-nine patients were studied, 12 with and 37 without previous immunotherapy. Forty patients were evaluable for response. A partial remission was noted in two patients, stable disease in 17 and progressive disease in 21. Toxicity was moderate and reversible and consisted mainly of fever, flu-like symptoms, nausea, weight loss and hepatotoxicity. Anaemia, leucocytosis and thrombocytosis and induction of acute phase protein synthesis were noted in most patients. In 15% of the patients anti-IL-6 antibodies developed, and were neutralising in only one patient. Baseline plasma IL-6 concentrations did not correlate with tumour behaviour before or after rhIL-6 treatment. In conclusion, rhIL-6 can be safely administered on an outpatient basis for prolonged period of time and has moderate, reversible toxicity. Its administration induces IL-6-antibody production in only a minority of patients. Antitmour effects of rhIL-6 in metastatic renal cancer are limited.

Cancer anorexia-cachexia syndrome (CACS), which is characterized by progressive weight loss (WL) and anorexia (A), is present in 50% of advanced cancer patients and in 80% of terminally ill cancer patients. One of the most controversial aspects of CACS is its oetiopathogenesis; experimental studies have identified certain cytokines [Tumour necrosis factor alpha (TNF-alpha), interleukin 1 (IL-1), interleukin 6 (IL-6), and gamma interferon (gamma-IFN)] as possible co-factors in the onset of the syndrome. The aim of our study was to investigate the correlation between serum levels of circulating cytokines and severity of CACS. The following series of parameters was identified in 61 patients with advanced and terminal cancer: stage of disease; Karnofsky performance status (KPS) and clinical symptoms; biohumoral, anthropometric and immunological situation; level of circulating cytokines. All these parameters were evaluated for a possible link with WL/A. Our data do not show any significant correlation between circulating cytokines and WL/A. A direct correlation was identified between WL/A and nausea (P = 0.03 and P < 0.001, respectively) whereas inverse correlations were observed for both factors as regards arm circumference (P < 0.001 for both), wrist circumference (P < 0.001 for both), KPS (P < 0.001 and P = 0.003, respectively) and creatinine (P = 0.005 and P = 0.03, respectively). Other biochemical factors, such as haemoglobin, haematocrit, glycaemia, prealbumin, sodium and chlorine were also correlated with at least one of two clinical parameters in question. Unexpected results were seen in the increases in CD20 and CD4 and in the CD4/CD8 ratio. Serum levels of these cytokines do not, therefore, appear to be critical in the onset of CACS. On the contrary, our findings confirmed the clinico-laboratory picture that is characteristic of CACS. If we consider the possibility that CACS is provoked by an aspecific response of the host's defence mechanisms against prolonged neoplastic attack, the increase in CD4 (helper lymphocytes) could be linked to the persistent response.
