Twenty-eight evaluable patients with metastatic cancer refractory to standard therapy received escalating doses of muramyl tripeptide phosphatidylethanolamine (MTP-PE) (.05 to 12 mg/m2) in phosphatidylserine (PC):phosphatidylcholine (PS) liposomes (lipid:MTP-PE) ratio 250:1). Liposomal MTP-PE (L-MTP-PE) was infused over 1 hour twice weekly; doses were escalated within individual patients every 3 weeks as tolerated for a total treatment duration of 9 weeks. Routine clinical laboratory parameters, acute phase reactants and various immunologic tests were monitored at various time points during treatment. Toxicity was moderate (less than or equal to grade II) in 24 patients with chief side effects being chills (80% of patients), fever (70%), malaise (60%), and nausea (55%). In four patients L-MTP-PE treatment was deescalated due to severe malaise and recurrent fever higher than 38.8 degrees C. The maximum-tolerated dose (MTD) was 6 mg/m2. Significant (P less than .05) increases in WBC count, absolute granulocyte count, ceruloplasmin, beta 2-microglobulin, c-reactive protein, monocyte tumoricidal activity, and serum IL-1 beta were found. Significant decreases in serum cholesterol were also observed. Clearance of intravenously (iv)-infused technetium-99 (99mTc)-labeled liposomes containing MTP-PE in four patients was biphasic; gamma camera scans revealed uptake of radiolabel in liver, spleen, lung, nasopharynx, thyroid gland, and tumor (two patients). No objective tumor regression was seen. In view of its definite immunobiologic activity and lack of major toxicity, additional phase II and adjuvant trials of L-MTP-PE are warranted.

The use of alpha interferon (alpha IFN) and, more recently, of the purine analogues deoxycoformycin (dCF) and 2-chlorodeoxyadenosine (2-CdA) has dramatically improved the prognosis of patients affected by hairy cell leukemia (HCL). DCF has been shown to induce an higher and more durable response rate than IFN, with only moderate myelosuppression and relatively few side effects. In this paper, we report our experience with dCF in a series of 38 HCL patients who had progression of their disease after IFN therapy. Serum interleukin-1 beta (IL-1 beta), soluble interleukin-2 receptors (sIl-2R) and Tumor Necrosis Factor alpha (TNF alpha) levels were also evaluated before, both during and after treatment in order to monitor clinical response. Two schedules of treatment were employed: 23 patients were treated with the EORTC protocol and the following 15 with the NCI regimen. The overall response rate was 94.7%; no significant differences in response rates were observed between the two schedules. In respect to toxicity, we recorded nausea and in two cases a cutaneous rash. Four patients experienced localized herpes zoster and one had a fungal pneumonia. Median overall survival after therapy is 38.5 months, 55 percent of patients enrolled in the EORTC schedule and 77% of those who received the NCI program are currently in CCR at 3 years. Serum IL-1 beta and sIL-2R levels significantly decreased after treatment, while no significant changes in serum TNF alpha levels were observed. In our study, dCF was confirmed as an effective agent in HCL, inducing an high response rate with only moderate side effects.(ABSTRACT TRUNCATED AT 250 WORDS)

The macrophage activator muramyl tripeptide-phosphatidyl ethanolamine (MTP-PE) was infused in liposomal form in 14 metastatic cancer patients (4 mg i.v. during 30 min twice weekly for 12 weeks). Clinical, pharmacokinetic and immunological parameters were studied before and 0.5, 2, 4, 24 and 72h after start of drug infusion in week 1, 4, 8 and 12. No tumor regressions were seen. Tumors progressed in 11 patients, in 4 of them within 2 months; 3 patients had stable disease. The intensity and frequency of side effects (fever and nausea) diminished from week 1 to 12. The rate of disappearance of total and free MTP-PE from blood was rapid and mean serum concentration-time curves remained unchanged throughout 12 study weeks. MTP-PE caused a marked increase of serum TNFa, IL-1 receptor antagonist (IL-1ra) and IL-6 in week 1, but not thereafter. In contrast, MTP-PE caused a persistent, 2-fold increase in serum neopterin and young forms of granulocytes (bands) during week 1 to 12. Before therapy, monocyte tumor cytotoxicity and in-vitro monocyte derived TNFa, IL-1 beta and IL-6 production were low in 9 patients (group L, < 15%) and high in 5 patients (group H, > 40%). Monocyte cytotoxicity and in-vitro cytokine production was transiently enhanced in week 1 in group L, it declined under therapy in group H. In conclusion, MTP-PE induced marked initial immunomodulation; the extent of the ex vivo monocyte cytokine and tumor cytotoxic response was dependent on pre-therapy cell activity. A decrease of the cytokine and IL-1ra response during prolonged therapy contrasted with a persistent increase of neopterin and juvenile blood granulocytes. The long lasting biologic effects may be relevant to direct future clinical studies with liposomal MTP-PE in an adjuvant setting.

To define the toxicity profile of recombinant human interleukin-6 (rhIL-6) and to study its effect on hematopoiesis, biochemical parameters and other cytokines, rhIL-6 was administered in a phase I-II study to 20 patients with breast carcinoma or nonsmall cell lung cancer. RhIL-6 doses were 0.5, 1.0, 2.5, 5.0, 10, and 20 micrograms/kg/d, with at least three patients per dose level. RhIL-6 was administered 24 hours by continuous intravenous infusion followed by subcutaneous (SC) administration for 6 days, partly on an outpatient basis. RhIL-6-related side effects were fever, headache, myalgia, and local erythema. Starting at 2.5 micrograms/kg/d, these side effects were compounded by nausea, reversible increase in liver enzymes, and anemia. Flu-like symptoms were controllable up to and including 10 micrograms rhIL-6/kg/d with acetaminophen. RhIL-6 increased platelet counts with a decrease in mean platelet volume and increased leukocytes caused by neutrophil, monocyte, and lymphocyte increase, with an increase in T cells and natural killer cells at 1.0 and 2.5 micrograms rhIL-6/kg/d. The reversible anemia was characterized by a decrease in serum iron, and an increase in ferritin and erythropoietin without reticulocytosis. RhIL-6 reduced total cholesterol levels and a dose-related increase of C-reactive protein and serum amyloid A plasma levels was observed. Serum IL-6 levels were increased, especially at 10 and 20 micrograms/kg/d, whereas no change in IL-1 beta and tumor necrosis factor alpha levels was observed. RhIL-6 can be administered with controllable side effects in this setting, up to and including a SC dose of 10 micrograms/kg/d on an outpatient basis, and has a promising stimulating effect on leukopoiesis and thrombopoiesis.
