XOMAZYME-Mel (XMMME-001-RTA) is an immunoconjugate comprised of ricin A chain conjugated to a murine monoclonal antibody directed against high molecular weight melanoma antigens. Although not necessarily related to increased toxicity or decreased efficacy, the development of anti-immunoconjugate antibodies may limit repetitive dosing with an immunoconjugate. We evaluated the role of cyclosporine A in blocking the antibody response in patients with melanoma treated with XMMME-001-RTA. Patients received cyclosporine in divided daily doses to achieve serum levels by HPLC of 150-200 ng/ml on days 1-22. On day 3, XMMME-001-RTA was begun at dosages 0.2-0.6 mg/kg daily for 5 days. Treatment was repeated every 35 days. Three patients were treated in each dosage tier (0.2, 0.4, 0.6 mg/kg). Nine patients were entered and all nine were evaluable. Patients had histologically confirmed melanoma. Metastatic sites included skin, soft tissue, and lymph nodes (seven), lung (two), liver (one), and spleen (one). There were four men and five women aged 46-75 years. Toxicities included myalgia, arthralgia, hypoalbuminemia, fatigue, elevations in liver function tests, and increased peripheral edema. Four patients received two to five repeated dosages of XMMME-001-RTA. One wheal-and-flare reaction from an immunotoxin test dose of XMMME-001-RTA was noted after five cycles. After a test dose subsequent to one cycle, two patients experienced chest tightness without ECG changes and were removed from the study. All toxicities resolved without sequelae. One patient experienced partial lymph node remission for 9 months. A second patient had stable mediastinal disease for 20 months. XMMME-001-RTA is safe when given repeatedly with cyclosporine.

Following extensive phase II trials of the combination of dacarbazine and interferon-alpha 2a we performed a prospective, randomized, controlled trial of this combination versus dacarbazine alone as systemic therapy for symptomatic, measurable metastatic malignant melanoma. The two treatment arms were well matched for age, sex, performance, status, relapse-free survival, prior therapy and sites of disease. Therapy consisted of dacarbazine given in combination in escalating doses of 200 mg/m2, 400 mg/m2 and 800 mg/m2 i.v. every 3 weeks, or alone at 800 mg/m2 i.v. every 3 weeks. Interferon was administered subcutaneously starting at 3 mU daily on days 1-3, 9 mU daily on days 4-70, then 9 mU three times per week. Therapy was continued for at least 6 months unless overt progressive disease was observed. Eighty seven patients were randomized to the combination and 83 patients to dacarbazine alone. Response rates were respectively, complete 7% and 2%, and partial 14% and 15%, for a total response rate of 21% (95% confidence limits 13-31%) and 17% (95% confidence limits 10-27%). Median duration of response was 258 and 286 days, and survival of the whole groups 229 and 269 days respectively. Toxicity was worse in the combination arm, with more patients experiencing fatigue, nausea and anorexia, flu-like symptoms and neutropenia. However quality of life was not significantly different in either group, except that fatigue, as measured at week 12 by LASA scales, and activity, as measured by the functional living index, were both improved in the combination.(ABSTRACT TRUNCATED AT 250 WORDS)

The primary purpose of this study was to determine if a psychoeducational nursing intervention including (a) health education, (b) stress management, and (c) the teaching of coping skills could enhance the coping behavior and affective state of newly diagnosed Stage I/II malignant melanoma patients. The secondary purpose was to determine if this intervention could be implemented by a nurse and integrated into the overall patient care program. Sixty-one patients were randomized to a control condition or an experimental condition that received and educational manual plus 3 h of individual nurse teaching. Despite randomization, experimental patients had significantly higher baseline distress. By 3 months there was a complete reversal of the baseline trend in Profile of Mood States (POMS) total mood disturbance (TMD), suggesting that the experimental subjects were experiencing less distress over time. Between-group analysis of change scores found significant decreases in experimental subjects for POMS TMD, fatigue, and Brief Symptom Index (BSI) somatization. Within-group analysis found significant experimental decreases for BSI somatization, anxiety, grand total, General Severity Index, and Positive Symptom Distress Index as well as for POMS anxiety, fatigue, confusion, vigor, and TMD. No significant changes were found for controls. Experimental patients were using significantly fewer ineffective passive resignation coping strategies than controls at 3 months.

Thirty-four patients with advanced malignant melanoma were treated with recombinant alpha-interferon (IFN) and chemotherapy consisting of carboplatin, vinblastine, and bleomycin (CVB). CVB was given for four cycles and IFN for 1 year or until progression. Of the 34 analyzed patients, 17 (50%) achieved an objective response, including two complete (6%) and 15 partial responses (44%). Responses were noted in cutaneous, lymph node, and pulmonary sites, with a median time to disease progression of 5 months (range, 3-20 months). The median survival from onset of therapy was 8 months (range, 1-22 months) for the 34 patients. Ninety-four percent of the patients experienced flu-like symptoms and 82% fatigue or weakness. Leukopenia grade 3-4 was observed in four patients (12%). There were two toxicity-related deaths (6%); one from bleomycin-induced pneumonitis and one from neutropenic sepsis. It is concluded that the addition of IFN to CVB regimen, in this study, showed no apparent advantage on response rates, disease-free interval, or survival. The observed treatment-related mortality was unacceptably high. IFN administered as maintenance therapy following CVB conferred no survival benefit.

Twenty-five patients with metastatic malignant melanoma were treated with isotretinoin (13-cis-retinoic acid) orally at 1 mg/kg daily and recombinant interferon alfa-2a (INF-alpha) subcutaneously at 3 million units daily for 16-48 weeks. Therapy was well tolerated; fatigue and hyperlipidemia were the most frequent dose-limiting toxicity and necessitated dose reductions in 14 patients. Two patients achieved a complete response, and 3 responded partially for a total response rate of 20% (95% confidence interval: 4-36%). Responses occurred primarily in patients with limited tumor burden and disease confined to the skin and lymph nodes. Significant elevations in peripheral blood 2'-5'-oligoadenylate synthetase activity and natural killer activity were observed with therapy. The magnitude of these changes, however, was not predictive of response. Biopsy specimens of two responding lesions showed extensive necrosis of tumor. One specimen showed large aggregates of melanophages in association with tumor. The combination of isotretinoin and IFN-alpha is an active, easily administered regimen with acceptable toxicity for metastatic malignant melanoma.

A phase II study was undertaken to evaluate the clinical efficacy and safety of docetaxel in patients with malignant melanoma. Between April 1992 and February 1996, 37 patients with metastatic malignant melanoma and no prior chemotherapy were treated with docetaxel 100 mg m-2 administered intravenously over 1 hour every 21 days. Patients were premedicated prior to each course with dexamethasone and diphenhydramine. Toxicity and follow-up were provided. Objective responses were seen in two out of 35 patients evaluable for response, one complete response and one partial response. These two responses were of a duration of greater than two years. The most common toxicity was grade 4 neutropenia, which occurred in 92% of patients; 49% required hospitalization for an episode of neutropenic fever. Additional patients had reversible grade 3-4 toxicities including nausea, vomiting, diarrhea, stomatitis, arthralgias, myalgias, peripheral neuropathy and fatigue. Eighteen patients had hypersensitivity reactions, two were grade 3-4. Fluid retention, grade 1-3 was observed in seven patients. Alopecia occurred in most patients. Docetaxel has definite but low-level activity against malignant melanoma. Further investigation of this drug should be considered in multidrug combination programs.

High response rates in patients with metastatic melanoma have been achieved with combination chemoimmunotherapy. A response rate of 62% in 45 patients has been reported for treatment with dacarbazine, bleomycin, vincristine, lomustine (BOLD) plus interferon alpha (IFN-alpha). We conducted a multicentre phase II study to confirm these results. Melanoma patients with distant metastases were treated as outpatients with dacarbazine 200 mg m(-2) on days 1-5, vincristine 1 mg m(-2) on days 1 and 4, bleomycin 15 mg on days 2 and 5 i.v. and lomustine 80 mg orally on day 1, repeated every 4 weeks. IFN-alpha-2b was initiated s.c. on day 8 at 3 MU daily for 6 weeks, and 6 MU t.i.w. thereafter. Forty-three patients entered the study. The median number of metastatic sites was three (range 1-5), and 81% of patients had visceral metastases. Nine patients had brain metastases, and seven patients were systemically pretreated. Among the 41 patients that were evaluable for response, the response rate was 27% (95% CI 14-3%), with one complete and ten partial remissions. The response rate in 25 previously untreated patients without brain metastases was 40% (95% CI 21-61%). Median duration of response was 6 (range 2-14+) months; median overall survival was 5 (1-26) months. The main toxicity was malaise/fatigue. We confirm that BOLD plus IFN-alpha has activity in metastatic melanoma. The lower response rate in our study compared with the previous report is probably related to patient selection, as in the previous study 46% of patients had stage III disease, whereas all our patients had stage IV disease, which is associated with a worse prognosis.

Two forms of recombinant interferon-alpha (IFN-alpha2a and IFN-alpha2b) have been approved by the Food and Drug Administration for a variety of clinical indications, including hairy cell leukemia, hepatitis, acquired immunodeficiency syndrome-related Kaposi's sarcoma, chronic myelogenous leukemia (IFN-alpha2a only), and adjuvant therapy for melanoma (IFN-alpha2b only), based on their proven clinical efficacy and acceptable safety profiles. The continued postmarketing monitoring of adverse reactions associated with IFN-alpha therapy has revealed some new toxicities. The most common adverse events associated with IFN-alpha therapy are flu-like symptoms, fatigue, anorexia, and central nervous system and psychiatric reactions. In particular, the incidence of depression has only recently been fully appreciated. Some of these side effects, particularly chronic fatigue, anorexia, and neuropsychiatric reactions, may become dose limiting. New approaches to minimize and manage the side effects of IFN-alpha therapy are needed.

Amyloid deposition in skeletal muscle is a well-recognized but rare occurrence. Sixteen such cases seen in a 17-year period (1979 to 1996) out of a total of 3,937 muscle biopsy specimens (0.004%) form this study group. Either Congo red or sulfated alcian blue stains were routinely performed in each biopsy to screen for amyloid. Patients in this study (eight men, eight women) ranged in age from 42 to 90 years (mean, 61 years) at initial presentation. The most common symptoms at presentation included weakness/fatigue (n = 10), autonomic symptoms (n = 8), and weight loss/decreased appetite (n = 7). Five patients had a concomitant malignancy (myeloma, n = 3; malignant carcinoid tumor, n = 1; melanoma, n = 1). Two patients had known hereditary forms of amyloidosis. Five patients had amyloid diagnosed on another organ biopsy (excluding peripheral nerve). Histologically, amyloid was deposited in the interstitium or perivascular region in 14 muscles and endomysial region in seven muscles. All cases were confirmed with Congo red staining (apple green birefringence) or by electron microscopic identification of fibrillary amyloid material. Scattered angular atrophic esterase-positive muscle myofibers indicative of acute denervation atrophy were seen in 14 muscles. Eight muscles showed small group atrophy, and seven showed myofiber type grouping. Scattered regenerating muscle fibers were seen in nine cases, degenerating myofibers in six, and foci of chronic endomysial and perivascular inflammation in two. Four muscles showed type II muscle fiber atrophy. A concomitant sural nerve biopsy specimen was evaluated in seven patients; all seven contained amyloid, confirmed either by Congo red staining or electron microscopic examination. In two nerves, there was a mild loss of myelinated axons; four had a moderate loss, and one, severe loss. Six of seven nerves showed predominantly axonopathic changes. In conclusion, (1) the prevalence rate of amyloid myopathy in muscle biopsy specimens was low (in this series, 0.004%); (2) only a minority of patients had multiple myeloma, and most presented with muscle weakness/fatigue or autonomic symptoms; (3) most of the muscles showed neurogenic features histologically; (4) all concomitant sural nerve biopsy specimens contained amyloid, and most showed a predominance of axonopathic changes.

This study examined the effects of moderate and prolonged exercise on 1) lung tumor metastases and 2) alveolar macrophage antitumor response in vitro. C57B1/6 mice were assigned to either Ex-30 (30-min run), Ex-F (run to fatigue), Ex-F-24 h (run to fatigue 24 h before tumor injection), or Con (rested in lanes above the treadmill). Mice received intravenous injections of syngeneic B16 melanoma cells 30 min postexercise. Lungs were removed 7 or 10 days later, and tumor foci were counted. Ex-F had fewer tumors than either Ex-30 or Con, whereas Ex-F-24 h also showed a strong trend toward fewer tumors. The initial localization of tumor cells in the lungs after injection was not different among groups. For the in vitro experiment, mice were killed immediately after exercise or 8 h later. Alveolar macrophages were removed and cultured in vitro with B16 melanoma cells. The growth of the tumors cultured with macrophages from Ex-F was lower than Con after exercise and, to a lesser extent, 8 h later. In Ex-30, this effect was only found immediately after exercise. The data suggest that prolonged exercise has a protective effect on lung tumor metastases and enhances alveolar macrophage antitumor cytotoxicity.
