Neocarzinostatin (NCZ), an acidic polypeptide antibiotic, was given to 47 patients with cancer and leukemia, and tolerance to two schedules, a single dose given as a 2 hour infusion and a continuous infusion over 5 days was investigated. Immediate reactions, including fever, chills, rigor, hypertension and mental confusion, were dose-limiting for the 2 hour infusion schedule, occurring at 3000 U/m2 and higher. Continuous administration for 5 days eliminated the immediate reactions and then hematological toxicity--often prolonged leukopenia and thrombocytopenia--became dose-limiting. Other toxicities of NCZ at both dose schedules included anemia, fever and chills, anorexia, nausea and vomiting, hepatic dysfunction, azotemia, hypophosphatemia, aminoaciduria, stomatitis, phlebitis and/or cellulitis at the venous infusion site and pruritus. Patients with solid tumors who had received little or no prior chemotherapy and had good bone marrow reserve tolerated up to 6000 U/m2/24 hours X 5 days. One patient with previously treated acute myelocytic leukemia was induced into a good partial remission lasting 10 weeks.

During the first week of March 1974, a hospitalized patient being evaluated for hyperproteinemia and hypertension experienced fever, chills, and myalgia and showed pulmonary signs consistent with diffuse pneumonia. Subsequently, the findings from serologic tests confirmed that the patient had viral influenza. Seven other compromised hosts on the same ward developed symptoms of pneumonic influenza, and serologic data on three of the seven confirmed influenza A2. Additionally, a previously healthy young adult admitted with acute respiratory distress died of nonbacterial complications and was shown to have community-acquired influenza. The unusual features of the epidemic were the intrahospital localization of the epidemic in compromised hosts, the high rate of pneumonic complications, the low rate of secondary bacterial infection, and the severity of the viral pneumonia in the community-acquired case.

Treatment with the monoclonal antibody OKT3 specific for the CD3 complex associated with the T cell antigen receptor can reverse acute rejection of human renal allografts. However, efficacy of anti-CD3 antibodies for treatment of patients with acute graft-versus-host disease after marrow transplantation has not been established. The dose-limiting side effects resulting from T cell activation induced by some anti-CD3 antibodies in vivo have discouraged their use for this application. We now report a phase I-II study of GVHD treatment with the anti-CD3 antibody BC3, a monoclonal murine IgG2b that, unlike OKT3, does not activate T cells. Fourteen patients were treated with BC3 after progression of acute GVHD despite treatment with cyclosporine and corticosteroids, and three patients received BC3 as primary treatment for GVHD. BC3 was administered at a dose of 0.1 or 0.2 mg/kg/day for seven or eight days. Five patients achieved complete resolution of GVHD, eight patients had partial improvement, two patients had no change, and two patients had progression of GVHD on therapy. Responses were sustained in 8 of 13 patients. Mild chills, fever, hypertension, and chest discomfort occurred in various combinations following 6 of 17 (35%) initial infusions of BC3 and following 4 of 99 (4%) subsequent infusions. In each instance it was possible to continue BC3 therapy without adjusting the dose or treatment schedule. In each patient treated, the absolute count of peripheral blood lymphocytes decreased transiently but returned to baseline within 22 hr after the first infusion. Circulating T cells had surface CD3 molecules saturated by the infused antibody in all but one patient. Four patients survived longer than one year after treatment with antibody BC3, and 13 patients died of infection or organ failure. Administration of the nonmitogenic anti-CD3 antibody BC3 was associated with improvement in the clinical manifestations of GVHD with minimal acute toxicity. Efficacy of antibody treatment did not depend on depletion of circulating T cells. Therefore, antibody BC3 may be achieving therapeutic immunosuppression by modulating T cell function. Controlled studies in patients treated earlier in the course of GVHD should determine whether antibody BC3 can improve survival.

Besides general complications of immunosuppression such as increased susceptibility to opportunistic infections or malignancy, individual immunosuppressive agents are associated with specific side effects. Nephrotoxicity is the major side effect of cyclosporine (CsA). Various attempts have been made to minimize this toxicity, such as monitoring drug blood levels, modifying the protocol, and coadministering other agents. Other side effects caused by CsA are hepatotoxicity, hyperkalemia, hypertension, tremor, gum overgrowth, and hirsutism. Azathioprine (AZA) causes dose-related bone marrow suppression, commonly leading to leukopenia. Careful monitoring of complete blood cell count and dosage adjustment according to white blood cell count are usually adequate to prevent serious leukopenia. The side effects of corticosteroids are numerous and include slow wound healing and de novo insulin-dependent diabetes mellitus. Many complications are dose related, and with low dosage or discontinuation of steroids, their frequency rapidly decreases. Antilymphoblast and antithymocyte globulins (P-ALG) are foreign antibodies and may cause allergic-type reactions such as fever, chill, and hypotension. The initial side effect of monoclonal antibody (muromonab-CD3, OKT3) is similar to that of P-ALG. It includes high fever, shaking chills, headache, rigors, and hypotension. To prevent it, acetaminophen, an antihistamine, and a steroid usually are administered before injection. Because this agent is also associated with high frequency of pulmonary edema, it should not be given to any patient who has more than 3% body weight gain during the week prior to therapy. In rare case, it causes aseptic meningitis or encephalopathy, which is manifested by fever, severe headache, and seizure.

Sixteen patients with relapsed non-Hodgkin's lymphoma underwent autologous bone marrow transplantation and infusion of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF). Treatment consisted of involved-field radiotherapy, cyclophosphamide 60 mg/kg/d intravenously (IV) for 2 days, and fractionated total body irradiation (1,200 cGy). Autologous bone marrow was thawed and infused IV, followed 3 hours later by the first infusion of IV rhGM-CSF 11 micrograms/kg/d over 4 hours. Infusions of rhGM-CSF were continued daily until either both neutrophil count exceeded 1,500/microL and platelet count exceeded 50,000/microL, or until 30 days after marrow re-infusion. Toxicities encountered were mild and included fever, chills, hypertension, alopecia, rash, diarrhea, stomatitis, myalgias, and synovial (knee) effusions. Neutrophil recovery greater than 500/microL occurred a median of 14 days (range, 9 to 30 days) after marrow infusion, significantly earlier than in a comparable group of historic controls who recovered counts at a median time of 20 days (range, 12 to 51 days) (P = .00002). Median time to self-sustaining platelet counts greater than 20,000/microL was 23.5 days (range, 12 to 100 days), comparable with the historic group (P = .38). One bacteremia (central venous catheter exit site infection with Staphylococcus epidermidis) and one local infection (Giardia lamblia in stool) occurred. Patients received a median of 11.4 (range, 4.4 to 20.2) x 10(4) colony-forming unit granulocyte-macrophage (CFU-GM) progenitors per kg. Stem cell progenitors CFU-GM, CFU-granulocyte, erythroid, monocyte, megakaryocyte (CFU-GEMM), and burst-forming unit-erythroid (BFU-E) were detected in the bone marrow as early as 7 days after marrow re-infusion, and increased in proportion to peripheral blood counts, but by 30 to 60 days still remained much lower than before transplant. Neutrophils transiently decreased in 13 of 16 patients (median decrease, 42%) within 24 to 72 hours of discontinuing rhGM-CSF infusions. These data suggest that rhGM-CSF therapy enhances neutrophil recovery by forcing stem cells to produce mature elements at an enhanced rate but may not affect marrow stem cell and early progenitor population sizes.

A 70-year-old woman was treated for renal cell carcinoma with recombinant human tumor necrosis factor, 450,000 U/m2 of body surface area, daily for 5 days, once a month. She had had psoriasis for 25 years. After two courses of recombinant human tumor necrosis factor her psoriasis resolved. A 40-year-old man with severe psoriasis was subsequently treated with a total of seven complete and incomplete 5-day courses of recombinant human tumor necrosis factor at doses of 50,000 to 300,000 U/m2/day. Significant toxicity (fever, chills, hypertension, and hypotension) was encountered. Partial resolution of the lesions was seen. Tumor necrosis factor is an active agent in psoriasis.

Fluosol, a perfluorcarbon emulsion, has the ability to carry oxygen in solution. In conjunction with oxygen breathing and radiation, Fluosol has been shown in animal models to enhance local tumor control. In September 1985, a Phase I/II Study was instituted to evaluate the effect of this adjuvant therapy with radiation in non small cell carcinoma of the luing. Fifty patients were enrolled in the study which was closed for accrual in November 1987. Five patients were withdrawn prior to the institution of radiation: one patient diagnosed with bone metastasis and four patients withdrawn due to mild to moderate reactions to Fluosol. Of the 49 patients administered Fluosol, 34 mild to moderate adverse reactions were noted in 22 patients to either the test dose/infusion (16 reactions including withdrawn patients) or post infusion (18). Flushing, dyspnea and hypertension (test dose/infusion) and chills and/or fever (postinfusion) were the typical symptoms. Transient elevation of blood chemistries (SGOT, SGPT, alkaline phosphatase, BUN) were noted in some patients. Six patients had transient depression of WBC counts (toxicity scores of 1 or 2) and two patients had transient depression of platelets (toxicity score of 1). None of these altered treatment. Forty-five patients received Fluosol of which 34 completed the planned therapy. Six patients were diangosed with metastatic disease during therapy and three patients died of their disease during treatment. One patient was withdrawn due to ineligibility and one patient withdrawn due to moderate reactions to Fluosol during the 3rd and 4th infusions. The total dose of Fluosol was escalated from 42 mL/Kg to 49 mL/Kg in 5, 6, or 7 weekly infusions. Patients breathed 100% oxygen for a minimum of one-half hr prior to and during radiation treatment. Radiation therapy was administered at a daily fraction of 165 to 200 cGy per fraction to a total dose of 5940 to 6800 cGy. Seventeen of 34 patients (50%) achieved a complete response to treatment and 11 patients (32%) had a partial response. Thirteen patients remain alive (range of 12 to 20 months) including 10 of 17 complete responders, 2 of 11 partial responders, and 1 treated with chemotherapy postradiation. The median absolute survival time of the patients completing therapy was 15.5 months and the 12 and 18 month absolute survival rates were 81% and 74%, respectively. The 45 patients starting protocol therapy had a median absolute survival of 9.2 months with a 12-month and 18-month survival of 45% and 35%, respectively.(ABSTRACT TRUNCATED AT 400 WORDS)

A phase I clinical trial of the macrophage activator, muramyl tripeptide-phosphatidylethanolamine has been carried out in 37 patients (47 courses) at doses of 0.01-6.0 mg/m2 intravenously twice weekly for 4 weeks. Activation of peripheral blood monocytes and drug toxicity were used as the parameters to monitor the trial. Toxicity was acute systemic responses of fever, chills, and hypertension without a clear dose response. No major organ-related toxicity was seen. A dose of 4.0 mg/m2 biweekly produced activation of blood monocytes; a dose of 6.0 mg/m2 produced inhibition. There was one complete response of 3 months duration in a patient with renal cell carcinoma with pulmonary metastases. The optimum dose for phase II studies is in the range of 1-4 mg/m2 twice weekly for 4 weeks, a dose that is well tolerated.

A murine IgG1 antibody specific for the IL-2-binding site on the human lymphocyte IL-2 receptor beta chain (CD25) was evaluated in 11 patients who developed acute graft-versus-host disease following allogeneic marrow transplantation. All patients had received cyclosporine and methotrexate for prophylaxis of GVHD, either alone (4 cases), or in combination with antithymocyte globulin (4 cases) or with prednisone (3 cases). Patients had developed GVHD at 7-53 days (median 12) after transplantation and had failed treatment with corticosteroids for 3-44 days (median 19). Residual GVHD was of grade II severity in 4 patients, grade III in 5 patients, and grade IV in 2 patients. Sequential patients received monoclonal antibody in escalating doses from 0.1 mg/kg/day to 1.0 mg/kg/day for 7 days. Side effects were fever, respiratory distress, hypertension, hypotension, and chills occurring in 11 of 72 (14%) antibody infusions. Trough antibody levels greater than 6 micrograms/ml were achieved in patients treated with 0.5 or 1.0 mg/kg/day. Four of eight evaluable patients had an IgM antibody response, and one had an IgG response to the murine immunoglobulin. Clinical response of GVHD was evaluated in 10 patients who received the entire course of the antibody treatment. Among 7 patients treated within 40 days from transplantation, one patient had a complete response in the skin as the only involved organ, and 3 patients had a partial response, 2 in the skin and one in the gastrointestinal tract. No responses were achieved with liver disease at anytime or in any organ in patients treated beyond 40 days after transplantation. Since administration of this antibody was well tolerated and some efficacy was observed in patients with acute GVHD treated early after transplantation, there is a rationale for testing this antibody as an agent for prophylaxis of GVHD.

Sixteen previously treated (with only one prior regimen) patients with histologically proven metastatic or locally recurrent colorectal carcinoma were treated with recombinant tumor necrosis factor (rTNF) administered by 30-minute i.v. infusions twice daily for 5 consecutive days every other week for 8 weeks. Patients received 100 micrograms/m2 twice daily on day 1 of cycle 1 with escalation to 150 micrograms/m2 twice daily thereafter. Patients were concomitantly treated with indomethacin 25 mg every 6 hours and acetaminophen 650 mg every 4 hours to obviate fever and chills. Toxicities included: nausea/vomiting (69%), headache (25%), chills (69%), pain at tumor sites (63%), hypotension (31%), and hypertension (38%). Hematologic toxicity included leukopenia less than 2000 cells/mm3 (38%) and thrombocytopenia less than 100,000 cells/mm3 (13%). Liver function abnormalities occurred independently of the site or extent of metastatic disease and inconsistently in each treatment cycle. Four patients developed bilirubinemia greater than 2.5 x baseline values (range, 2.5 to 10.3 U/L); five patients had greater than 2.5 x elevations in alkaline phosphatase (range, 624 to 1663 U/L). Two patients developed retinal vein thrombosis in the absence of hemostatic abnormalities. In both instances, this complication occurred several weeks after completion of therapy. No objective responses were noted in 14 evaluable patients (95% confidence interval: 0 to 0.23). Three patients had stable disease for a median duration of 4.5 months. In conclusion, i.v. rTNF at this dose and schedule has no demonstrable antitumor efficacy. Twice-daily i.v. administration of this agent is associated with more hepatotoxicity than previously reported in trials using subcutaneous or once daily i.v. administration. Retinal vein thrombosis may be a late complication of i.v. rTNF at this dose and schedule.
