RESUMEN
PURPOSE: To evaluate the toxicity and efficacy of combination chemotherapy with paclitaxel and gemcitabine in patients with advanced transitional-cell carcinoma of the urothelial tract. PATIENTS AND METHODS: Fifty-four patients with advanced unresectable urothelial carcinoma entered this multi-centered, community-based, phase II trial between May 1997 and December 1999. All patients were treated with paclitaxel 200 mg/m(2) by 1-hour intravenous (IV) infusion on day 1 and gemcitabine 1,000 mg/m(2) IV on days 1, 8, and 15; courses were repeated every 21 days. Patients who had objective response or stable disease continued treatment for six courses. RESULTS: Twenty-nine of 54 patients (54%; 95% confidence interval, 40% to 67%) had major responses to treatment, including 7% complete responses. With a median follow-up of 24 months, 16 patients (30%) remain alive and nine (17%) are progression-free. The median survival for the entire group was 14.4 months; 1- and 2-year actuarial survival rates were 57% and 25%, respectively. Seven (47%) of 15 patients previously treated with platinum-based chemotherapy responded to paclitaxel/gemcitabine. Grade 3/4 toxicity was primarily hematologic, including leukopenia (46%), thrombocytopenia (13%), and anemia (28%). Ten patients (19%) required hospitalization for neutropenia and fever, and one patient had treatment-related septic death. CONCLUSION: The combination of paclitaxel and gemcitabine is active and well tolerated in the first- or second-line treatment of patients with advanced transitional-cell carcinoma of the urothelial tract. Response rate and duration compare favorably with those produced by other active, first-line regimens. This regimen should be further evaluated in phase II and III studies, as well as in patients with compromised renal function.

PURPOSE: To evaluate the toxicity, response rate and short-term survival associated with the chemotherapy combinations of docetaxel plus cisplatin or carboplatin when used for the treatment of patients with metastatic carcinoma of unknown primary site. PATIENTS AND METHODS: Twenty-six patients were treated with docetaxel 75 mg/m2 i.v. and cisplatin 75 mg/m2 i.v. given every three weeks (study A) and subsequently, 47 patients were treated with docetaxel 65 mg/m2 and carboplatin (AUC dose = 6) every three weeks (study B). Stable or responding patients received a maximum of eight courses of therapy. Patients who were known to be in treatable subset groups were excluded from these trials. The majority of patients had two or more sites of metastasis; about 45% had adenocarcinoma and 50% poorly differentiated carcinoma. RESULTS: In study A, 6 of 23 (26%) assessable patients had a major response to therapy. The median survival was eight months and one-year survival 42%. Seven patients were removed from the study early for grade 3 or 4 nausea and vomiting. In study B, 9 of 40 assessable patients (22%) had a major response to therapy. Median survival was eight months and one-year survival 29%. Toxicity associated with this regimen was predominantly myelosuppression. Comparisons of the two sequential trials showed no differences in response rates or survivals (P = 0.75). CONCLUSIONS: Docetaxel and cisplatin (study A) is an active combination in carcinoma of unknown primary site, but associated with substantial gastrointestinal toxicity. A combination of docetaxel plus carboplatin (study B) is better tolerated and produced a similar response rate, median survival and one-year survival. Comparative phase III trials will be necessary to unequivically prove a survival advantage for any form of therapy in these patients. However, the survival for patients with carcinoma of unknown primary site receiving docetaxel-based chemotherapy is comparable to the survivals for several other groups of advanced cancer patients, such as non-small cell lung cancer, receiving various types of chemotherapy.

The purpose of this trial was to determine the toxicity and antineoplastic activity of cisplatin, carboplatin, tamoxifen, and interferon-alpha (IFN-alpha) in patients with advanced melanoma. Eleven patients with metastatic melanoma were enrolled. The patients received carboplatin 400 mg/m2 i.v. on day 0; cisplatin 25 mg/m2 i.v. on days 7, 14, and 21; tamoxifen 20 mg p.o. b.i.d. on days 0-27; and interferon-alpha 5 million units/m2 subcutaneously 3 times per week. Cycles were repeated every 28 days. Patients were assessed for tumor response at the end of 2 cycles. Toxicity was severe, with 14 of 24 cycles given requiring some form of dose reduction. Carboplatin dose reductions were related to bone-marrow toxicity, whereas IFN-alpha caused fatigue, arthralgias, myalgias, and fever. The overall response rate was 18% (2 partial responses [PRs]). The combination of cisplatin, carboplatin, tamoxifen, and IFN-alpha is active in advanced melanoma; however, the toxicity is unacceptable.

We performed a prospective, randomized study to determine whether subcutaneous administration of interleukin-2 (IL-2) in combination with an autologous renal cell vaccine is feasible and can potentiate antitumor immunity. Seventeen patients with metastatic renal cell carcinoma underwent surgical resection with preparation of an autologous tumor cell vaccine. Patients were vaccinated intradermally twice at weakly intervals with 10(7) irradiated tumor cells plus bacillus Calmette-Guérin, and once with 10(7) tumor cells alone. Patients were randomized to one of three groups: no adjuvant IL-2, low-dose IL-2 (1.2 x 10(6) IU/m2), or high-dose IL-2 (1.2 x 10(7) IU/m2). IL-2 was administered subcutaneously on the day of vaccination and the subsequent 4 days. Immune response was monitored by delayed-type hypersensitivity (DTH) response to tumor cells as compared with normal autologous renal cells. Sixteen of 17 patients received vaccine therapy. Four patients developed cellular immunity specific for autologous tumor cells as measured by DTH responses; two had received no IL-2 and two had received high-dose IL-2. There were two partial responses (PR) noted, both in patients who received high-dose IL-2. One responding patient was DTH(+) and one was negative. A third patient who was DTH(+) after vaccination with no IL-2 had a dramatic PR after receiving IL-2 subcutaneously in a subsequent protocol. Prospective testing of response to recall antigens indicated that only 5 of 12 tested patients were positive, including both clinical responders. These data suggest that subcutaneously administered adjuvant IL-2 does not dramatically augment the immunologic response to autologous renal cell vaccines as determined by the development of tumor-specific DTH response.

PURPOSE: Although high-dose interleukin-2 (IL-2) can produce durable remissions in a subset of responding patients with renal cell carcinoma (RCC), this occurs in the setting of significant toxicity. The purpose of this study is to define the maximum-tolerated dosage (MTD) of IL-2 and interferon alfa-2a (IFN alpha-2a) that can be administered chronically on an outpatient basis. PATIENTS AND METHODS: Fifty-three patients with advanced cancer of variable histology with good prognostic features were treated in six cohorts. Patients in cohorts one through five received IL-2 (1.5 or 3.0 x 10(6) million units (mU)/m2) Monday through Friday and IFN alpha-2a (1.5 or 3 x 10(6) mU/m2) daily for a 4-week cycle. In cohort six, IFN alpha-2a was given three times a week. Immunologic monitoring, including serum levels of soluble IL-2 receptor (sIL-2R) and neopterin, flow cytometry, and natural killer cell (NK) activity, were measured. Patients were evaluated for toxicity, response, and survival. RESULTS: Almost all patients developed grade I/II toxicities commonly associated with cytokine therapy. Symptoms were most severe with the first treatment of each week. Dose-limiting toxicities included grade III fatigue, hypotension, and creatinine elevations. The MTD was 1.5 mU/m2 daily x 5 given subcutaneously repeated weekly for IL-2 and 1.5 mU/m2 daily subcutaneously (dose level 3) for IFN. Six of 25 assessable patients with RCC (24%) achieved a partial response (PR), including four of eight patients who were previously untreated. There were no objective responses in patients with other tumors, including 12 melanoma patients. CONCLUSION: IL-2 and IFN alpha-2a can be given with tolerable toxicities on an outpatient basis and shows significant activity in patients with metastatic RCC.

BACKGROUND: The rising incidence of malignant melanoma and the lack of curative therapies for metastatic disease represent a therapeutic challenge. New agents effective in treating this disease are needed. PURPOSE: Because of the additive antitumor effects of interleukin 1 alpha (IL-1 alpha) and indomethacin in vivo, we conducted a phase II trial of this combination in patients with melanoma. We used the recommended dose determined from our phase I trial to ascertain the antitumor activity of the combination. METHODS: From August 1, 1990, through July 28, 1992, 49 patients entered the study. They were stratified into two groups based on the presence of visceral (n = 14) and nonvisceral (n = 35) metastases. The patients received 7 days of both IL-1 alpha (O.1 micrograms/kg per day by intravenous bolus) infusion) and indomethacin (50 mg orally every 8 hours). At least two cycles of therapy, repeated at 21-day intervals, were planned. Additional treatment was given to those patients who had stable or responding lesions. A chi-squared test for homogeneity of proportions was used to compare groups on several measures. All P values resulted from two-sided tests. RESULTS: Fever, chills, and hypotension were among the most common side effects. None of the 14 patients with visceral metastases responded to the treatment. Of the 35 patients with non-visceral metastases, three showed a partial response for 6 months each and one showed a complete response for more than 34 months; the response rate was 11% (95% confidence interval [CI] = 5%-26%). All responding patients required phenylephrine for treatment of IL-1 alpha-induced hypotension, whereas six (19%) of 31 of the nonresponding patients with nonvisceral metastases required phenylephrine (P = .0008). The response rate in women was higher; three of 10 women (30%; 95% CI = 11%-60%) responded, whereas one of 25 men (4%; 95% CI = 0%-20%) responded (P = .029). All three women were positive for human leukocyte antigen (HLA) B7 expression (P = .011). CONCLUSIONS: The combination of IL-1 alpha and indomethacin has minimal antitumor activity in melanoma patients. All responses were confined to patients with nonvisceral metastases. IL-1 alpha-induced hypotension, gender, and HLA B7 expression were positively associated with response. IMPLICATIONS: Administration of higher doses of IL-1 alpha alone has been shown to produce hypotension in a large proportion of patients but can be given safely with phenylephrine support. Because of the association of hypotension with antitumor activity, treatment with higher IL-1 alpha doses alone may be a strategy for attaining better response rates.

We conducted a phase I/II trial of 5-fluorouracil (5-FU), calcium leucovorin (LV), zidovudine (AZT) and dipyridamole (DP), (FLAP) in patients with metastatic colorectal cancer, renal cell carcinoma and malignant melanoma. AZT and DP were given to enhance the biochemical modulation and antitumor activity of 5-FU and LV. All patients received 5-FU (370 mg/m(2) i.v. bolus day 0-4), LV (50 mg/m(2) p.o. every 4 h day 0-4) and DP (50 mg/m(2) p.o. every 6 h days 0-27). In the phase I portion of the study, AZT was dose escalated in cohorts of 5 patients each, from 50 mg p.o. every 6 h days 0-27 to the MTD of 200 mg p.o. every 6 h days 0-27. Thirty-three patients received 200 mg of AZT in the phase II portion of the trial. Eleven patients developed grade III and 5 patients developed grade IV leukopenia. Four patients developed grade III and 21 patients developed grade IV neutropenia, with six febrile neutropenic episodes. Six patients experienced grade III anemia and four grade III thrombocytopenia. Diarrhea or stomatitis of greater than or equal to grade III occurred in six and four patients, respectively. Fifty-eight percent (19 of 33) of patients required dose reductions of AZT for hematologic toxicity (13 of 19 in the first treatment cycle). At the 200 mg AZT dose level, there were two partial responses in nine colorectal cancer patients (22%), no objective responses in 14 patients with renal cell carcinoma or in 14 patients with melanoma. FLAP does not have significant activity in melanoma, renal cell carcinoma or 5-FU-treated colorectal cancer patients, although it may have activity in untreated colon cancer.
RESUMEN
T-gamma lymphoproliferative disease (T-gamma LPD) is a chronic disorder of mature T cells that is associated with neutropenia and autoimmune phenomena. Although the progression of the lymphoproliferation is indolent, it is often associated with a monoclonal proliferation of T-cell-type large granular lymphocytes (LGL) that manifest multiple in vitro suppressor and cytotoxic activities. We considered the possibility that the granulocytopenia or anemia might represent an autoimmune disorder mediated by the monoclonal LGL via T-cell receptor (TCR) recognition of an antigen involved in hematopoiesis. Therefore, in an effort to characterize the usage of the TCR alpha- and beta-chain genes in patients with T-gamma LPD, we cloned and sequenced TCR alpha- and beta-chain mRNAs derived from the T-cell type LGL of five patients. The five patients studied did not use a common V alpha nor a common J alpha segment. However, an unusual finding was observed in one of the patients where the occurrence of a single variable-diversity-junctional (VDJ) rearrangement of the beta chain confirmed the monoclonal origin of the LGL proliferation. In accord with this evidence for monoclonality, many of the cells studied used a common V alpha (V alpha 19.1). In contrast to this common V alpha usage, there was a marked diversity of the J alpha segments and N-region addition that were associated with the V alpha 19.1 segment. This pattern of common V alpha usage associated with different N and J alpha segments suggests an immune-mediated selection process affecting the TCR alpha chain occurring after the transformation event that established the clone. We suggest that the T-cell-type LGL malignant clone might have developed autoreactivity conferred by the selected TCR alpha chain and that this autoreactivity might be implicated in this patient's anemia.

PURPOSE: In an effort to improve outcome in patients with metastatic or high-risk localized Ewing's sarcoma family of tumors (ESF) and rhabdomyosarcoma (RMS), we explored the role of consolidation therapy with total-body irradiation (TBI) plus autologous bone marrow transplantation (ABMT). PATIENTS AND METHODS: Ninety-one patients were entered onto one of three consecutive protocols from 1981 to 1986. Induction therapy consisted of four or five cycles of vincristine, doxorubicin, and cyclophosphamide (VAdriaC); in the earlier series, patients received one or two cycles with dactinomycin instead of doxorubicin. Irradiation of the primary site was used for local control. Patients who attained a complete response (CR) to induction therapy were eligible for consolidation with 8 Gy TBI plus VAdriaC and ABMT. RESULTS: Nineteen patients were ineligible for consolidation after failing to achieve or maintain a CR following induction therapy; all 19 are dead of disease. Seven eligible patients elected to forgo consolidation; three of seven are long-term event-free survivors. Sixty-five patients received consolidation therapy; 20 of 65 are long-term event-free survivors. A local control rate of 83% was achieved using radiation therapy as the primary modality of local control. Patients with metastatic disease at diagnosis fared substantially worse than did patients with localized tumors (6-year event-free survival [EFS] rate, 14% v 38%; two-sided P [P2] = .008). CONCLUSIONS: Consolidation of patients with metastatic or high-risk localized pediatric sarcomas with 8 Gy TBI plus ABMT has failed to improve the outcome of this group of patients. Metastatic disease at diagnosis continues to confer the poorest prognosis. New therapeutic strategies are needed to consolidate more effectively the remissions that can be achieved in the majority of these patients.

Interferon-gamma (IFN-gamma) is a potent monocyte/macrophage activating agent that in animal models exhibits a bell-shaped dose-response curve of immunomodulatory activity and antitumor efficacy. Previous clinical trials of IFN-gamma conducted at the maximal tolerated dose (MTD) have been associated with low response rates that may have been due to failure to treat at an optimal immunomodulatory dose (OID). The objective of this study was to test the hypothesis that optimal immunomodulatory activity of IFN-gamma in patients with metastatic melanoma would be obtained at a dose below the MTD. Groups of five patients each were given daily subcutaneous injections of IFN-gamma at doses of 0.01, 0.1, or 0.25 mg/m2. In vivo immunomodulation was assessed by serial measurement of serum neopterin and by flow cytometry. IFN-gamma doses of 0.1 or 0.25 mg/m2 induced significantly greater immunomodulation of monocyte-associated immune parameters than 0.01 mg/m2. Changes in immunologic parameters included marked elevation of serum neopterin levels, significant increases in monocyte expression of CD64, beta 2-microglobulin, and HLA-ABC, and decreased monocyte expression of CD14. The most dramatic decreases in CD14 expression were observed on monocytes obtained from patients treated at 0.25 mg/m2. The 0.25-mg/m2 dose group had significantly lower white blood cell counts on day 14. No bell-shaped curve of immunologic response was observed over the dosage range tested. Based on the similarity of the immunologic effects at 0.1 and 0.25 mg/m2, treatment at the MTD of IFN-gamma (0.25 mg/m2) represents treatment at the OID for patients with metastatic malignant melanoma.

PURPOSE: This phase I study was conducted to determine the maximum-tolerated dose (MTD) and the immunologic properties of levamisole in cancer patients when administered alone and in combination with interferon gamma (IFN-gamma). PATIENTS AND METHODS: Twenty patients with advanced cancer and 36 patients with completely resected melanoma (n = 33) or renal cell cancer (n = 3) received levamisole orally every other day for six doses at 1.0, 2.5, 5.0, or 10.0 mg/kg. Ten days later, patients restarted levamisole and began IFN-gamma 0.1 mg/m2 by subcutaneous injection every other day. Blood samples were collected for measurement of neopterin and soluble interleukin-2 receptor (sIL-2R), and for flow-cytometric analysis. RESULTS: The MTD of levamisole was 5 mg/kg, and this was not changed by the addition of IFN-gamma. Dose-related increases in serum levels of neopterin and sIL-2R were noted. Multiple doses of > or = 5 mg/kg of levamisole were required to elicit immune changes, which were more prominent in patients with minimal tumor burdens. Increased expression of CD64 and class I and class II major histocompatibility antigens on monocytes was also observed. The combination of IFN-gamma and levamisole did not result in greater immunologic effects than those observed in previous trials of IFN-gamma alone. CONCLUSION: Levamisole induces dose-related immunologic changes in patients with large or minimal tumor burdens. These changes may be involved in the beneficial effects noted in recent adjuvant trials of levamisole. Ongoing clinical trials should correlate immune changes with response, and trials exploring different schedules of administration using higher, more immunologically active, doses of levamisole should be performed.

PURPOSE: A phase I trial was undertaken because interleukin-1 alpha (IL-1 alpha) possesses antiproliferative, immunostimulatory, antiinfection, myeloprotective, and myelorestorative properties that could be beneficial in cancer treatment. PATIENTS AND METHODS: In this phase I trial, IL-1 alpha was administered intravenously (IV) during a 15-minute period daily for 7 days to patients with advanced solid malignancies. RESULTS: The maximum-tolerated dose (MTD) of IL-1 alpha alone was 0.3 microgram/kg. A second group of patients received indomethacin plus IL-1 alpha based on preclinical studies, which indicated that indomethacin could abrogate IL-1 alpha-induced hypotension; however, the MTD of IL-1 alpha plus indomethacin was 0.1 microgram/kg lower than IL-1 alpha alone. Fever, chills, headache, nausea, vomiting, and myalgia were common but were not dose-limiting. Hypotension resulted from a marked decrease in systemic vascular resistance and required pressors at 0.3 and 1.0 micrograms/kg IL-1 alpha. Dose-limiting toxicities included hypotension, myocardial infarction, confusion, severe abdominal pain, and renal insufficiency. IL-1 alpha treatment caused a significant, dose-related increase in the total WBC count (mainly segmented neutrophils and neutrophilic bands). Bone marrow cellularity increased because of enhanced numbers of relatively mature myeloid cells and megakaryocytes. Platelet counts decreased during therapy but were significantly elevated above baseline values 1 to 2 weeks posttreatment; this may have been an effect of IL-6 that was shown to be induced by IL-1 alpha treatment. Significant increases in triglycerides, cortisol, C-reactive protein, thyroid-stimulating hormone and decreases in cholesterol, testosterone, and protein-C were observed with treatment. CONCLUSION: We conclude that at doses of IL-1 alpha that can be given safely to cancer patients, significant, potentially beneficial hematopoietic effects occur.

OBJECTIVE: Based upon their individual clinical activity and combined effects in animal models or in vitro, we wished to evaluate a regimen of cisplatin, interferon-alpha, and IL-2 in patients with metastatic melanoma. DESIGN: Phase II pilot study. SETTING: Referral-based US Government clinical research unit. PATIENTS: Nine patients with metastatic malignant melanoma. INTERVENTION: Cisplatin 75-100 mg/m2 was administered intravenously over 30 minutes on days 1 and 8. Interferon-alpha 2a 5 Mu/m2 body surface area (BSA) was given subcutaneously for 4 days beginning 1 day before each dose of cisplatin. Beginning on day 15 and day 22, IL-2 was administered by intravenous continuous infusion at 3 Mu/m2 BSA/d for 96 hours and by daily intravenous bolus concurrent with daily subcutaneous doses of interferon-alpha 2a. MAIN OUTCOME MEASURES: Antitumor response and toxicities. RESULTS: The study was stopped due to renal and hematopoietic toxicity and severe, delayed nausea and vomiting associated with the cisplatin-interferon treatment. Three of 9 patients achieved a partial response (duration 2.5, 4, 14+ months), and an additional patient had a 50% reduction in measurable tumor volume before undergoing resection of residual disease. Overall response rate was 45%. CONCLUSION: This regimen was associated with excessive toxicity, and the lack of complete responses in a patient cohort with favorable characteristics for response (good performance status, predominance of skin and lymph node metastatic sites) suggests that it had no advantage over less toxic treatment regimens.

We have performed a phase IB study of polyinosinic-polycytidylic acid complexed with poly-L-lysine and carboxymethylcellulose (poly-ICLC) in combination with interleukin 2 (IL-2) in 25 patients with a variety of cancers. Patients received weekly or biweekly poly-ICLC by i.m. injection, at doses ranging from 0.01 to 1.0 mg/m2, for 1 month. This was followed by 2 months of outpatient therapy with biweekly i.m. poly-ICLC in combination with IL-2 (3 x 10(6) units/m2) given i.v. by 24-h continuous infusion twice weekly, using a portable infusion pump. No objective tumor responses were observed. Toxicity was moderate at all poly-ICLC doses tested and increased only slightly following the addition of IL-2. No increases in peripheral blood natural killer (NK) activity were observed after treatment with poly-ICLC alone. However, high dose poly-ICLC (greater than or equal to 0.3 mg/m2) in combination with IL-2 resulted in NK activity greater than that seen using the same dose of IL-2 in combination with lower poly-ICLC doses. Increases in the number and percentage of CD56+ cells were evident only after initiation of IL-2 therapy and were unaffected by the poly-ICLC dose. In the majority of patients, these increases were preferentially associated with the subset of CD56+ cells coexpressing CD8, while the CD56+/CD16+ population was elevated to a lesser extent. Moderate increases in serum neopterin levels and 2',5'-oligoadenylate synthetase activity in peripheral blood mononuclear cells were noted at 72 h following initial treatment with 1.0 mg/m2 poly-ICLC. No induction of alpha or gamma interferon was detected. This study shows that the addition of poly-ICLC to a well tolerated IL-2 regimen can significantly enhance NK activity. Poly-ICLC can be used to enhance IL-2-induced NK lytic activity without increases in the dose and, therefore, the toxicity of IL-2 treatment.

BACKGROUND: Experiments in animal tumor models suggest that the antitumor effects of interleukin-2 (IL-2) or IL-2 in combination with lymphokine-activated killer (LAK) cells can be enhanced by chemotherapy agents such as cyclophosphamide or doxorubicin or by the biologic agent interferon alpha. PURPOSE: We determined the toxicity and clinical response rate of an IL-2-LAK cell regimen modified by the addition of moderate, immunomodulatory doses of chemotherapy and sequenced with interferon alfa-2a (IFN alpha-2a) in patients with metastatic melanoma and renal cell carcinoma. METHODS: IL-2 (3-6 million units/m2 per day) was administered by continuous infusion on days 0-5 and days 11-16. LAK cells were infused on days 11 and 12 or on days 11, 12, and 14. Low doses of cyclophosphamide (300 mg/m2) and doxorubicin (25 mg/m2) were given on day 9 before the LAK cell infusions. Following the IL-2-LAK cell infusion, IFN alpha-2a (12 million units/m2) was administered for a total of nine doses to complete a cycle of treatment. A total of 89 patients were enrolled in the study. RESULTS: For each histology, there were eight partial responses in 40 assessable patients, for an overall response rate of 20% (90% confidence interval = 10%-33%). The median response duration was 5 months, although two patients with renal cell carcinoma and one patient with metastatic melanoma had almost complete disappearance of tumor and are still responding after 26+, 22+, and 26+ months, respectively. Toxic effects were severe in patients receiving the highest dose of IL-2 administered in this study and similar to those reported with other high-dose IL-2-LAK cell regimens. Although toxic effects were completely reversible in most patients, there were four treatment-related deaths. CONCLUSIONS: This regimen is active in patients with metastatic melanoma and renal cell carcinoma and produces meaningful responses in a small percentage of these patients; however, it is not clear whether cyclophosphamide, doxorubicin, and IFN alpha-2a as used in this protocol appreciably augmented the antitumor activity of the IL-2-LAK cell regimen.

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.

In light of in vitro and preclinical animal model data suggesting potential additive or synergistic antitumor effects from the combined use of interferon-gamma (IFN-gamma) and tumor necrosis factor-alpha (TNF-alpha), we conducted a phase I study employing escalating doses of each agent in 36 patients with solid tumors to determine the maximum tolerated dose (MTD). Patients were given an intramuscular (i.m.) injection of IFN-gamma, followed 5 min later by an i.m. injection of TNF-alpha, each agent in different sites, every other day for ten doses over 20 days. Patients received 10, 50, or 100 micrograms/m2 of each agent throughout the treatment course. No dose modifications were made. Patients suffering serious toxicity had therapy stopped and were considered to be off-study. All patients experienced fatigue, and 36% spent over half their time in bed on treatment days. Fever and chills were nearly universal. Mild to moderate elevations in serum transaminase levels were noted in 44% of patients, and 44% developed transient microscopic hematuria. Although 81% of patients had anorexia, only 17% of patients lost more than 3 kg of body wt during the 3 weeks of therapy. Because two of three patients receiving 100 micrograms/m2 of both agents developed serious toxicity (one fever greater than 105 degrees F, one thrombocytopenia 43,000/mm3), the MTD was established to be 100 micrograms/m2 of IFN-gamma plus 50 micrograms/m2 of TNF-alpha. The use of aspirin did not significantly alter the toxic effects of the agents. One patient with melanoma had a mixed response and one patient with mesothelioma transiently cleared his ascites of malignant cells.
