Ten of 23 patients with advanced measureable adenocarcinoma of the pancreas achieved an objective response after treatment with a regimen consisting of streptozotocin, mitomycin-C and 5-fluorouracil (SMF). The median duration of response is in excess of 7 months and responding patients have lived significantly longer than patients with progressive disease (7.5 + months vs. 3 months). The SMF regimen was adequately tolerated. Principal toxicities included myelosuppression, which was generally mild, nausea and vomiting. There was reversible nephrotoxicity in the form of proteinuria in 30% of patients and persistent axotemia in 9% of patients.

Streptozotocin (STZ) has shown antitumor activity against various tumors in man, but the clinical usefulness of this drug has been limited, mainly because of renal and gastrointestinal toxicity. Nineteen patients with advanced cancer of various types were given a mean dose of 3.4 g/m2 of STZ by continuous iv infusion over 5-6 days each month for one or two monthly cycles. Basic serum and urine studies were performed immediately before and after each treatment cycle. Following STZ treatment, no significant changes in BUN or creatinine were seen. Four patients in whom initial tests for proteinuria were negative developed grade 1 or 2+ proteinuria after completion of the treatment cycle. No myelosuppression or renal failure was observed. Six patients had no nausea or vomiting, seven patients had nausea only, three patients had nausea and vomiting which were well-controlled with antiemetics, and three patients had uncontrollable nausea and vomiting. Confusion, lethargy, and depression were noted in five patients who had no prior central nervous system abnormalities; these effects appeared during treatment or in the immediate posttreatment period. Two patients with diffuse non-Hodgkin's lymphoma had complete remission, while several other patients had documented improvement. Although central nervous system toxicity may be a limiting factor, prolonged STZ infusions may have significant clinical promise.

Spiroplatin was investigated in a multicentre phase I study. 67 patients with advanced solid tumours received 151 cycles either by short-term or prolonged infusion, repeated every 3 weeks, at 2.5-40 mg/m2. Myelosuppression and renal toxicity were dose-limiting. Proteinuria, which was dose- and schedule-dependent, indicated glomerular and tubular damage. The maximum tolerated doses (MTD) for poor-risk and good-risk patients were 35 and 40 mg/m2, respectively. The area under the curve (AUC) at the MTD did not correspond with the AUC at the LD10 in mice with ratios of 0.3 for free platinum and 2.6 for total platinum; these were not suitable for predicting the MTD. 1 complete response was observed in a patient with breast cancer and lung metastases and 1 partial response in a patient with adenocarcinoma of the lung. The recommended dose for phase II studies was 30 mg/m2 by 4 h infusion every 3 weeks.

Carbetimer (carboxyimamidate) was administered at a dose of 6,500 mg/m2/day intravenously for 5 consecutive days to 14 patients with measurable metastatic or recurrent colorectal cancer in a single institution phase II study of the Northern California Oncology Group. A total of 38 cycles of therapy were administered; nine patients completed at least three cycles of treatment. No partial or complete responses were observed. One patient did have a greater than 50% response in the liver while developing new retroperitoneal lymphadenopathy and is considered a nonresponder. Carbetimer was well tolerated with elevations of calcium from 10.2 to 12.5 mg/dl in nine patients, prolongation of prothrombin time and partial thromboplastin time in 14 patients, proteinuria in 10 patients, dizziness in six patients, nausea in two patients, and venous pain during infusion in three patients. Myelosuppression was not observed. Carbetimer at this dose and schedule is inactive in the treatment of colorectal cancer.

Recombinant human gamma interferon (Biogen) and vinblastine were administered in a phase I study. Side effects included fever and chills, nausea and vomiting, acute symptomatic hyponatremia, reversible myelosuppression, hepatitis, transient hypotension, congestive heart failure, renal insufficiency, and nonselective proteinuria. In most patients, additional host factors contributed to these toxic effects. Side effects occurred despite dose reduction; therefore, protocol accrual was prematurely closed. No correlation between serum concentrations and toxicity was noted. Median serum vinblastine concentration was 1.04 ng/ml; median serum interferon concentration was 17.3 IU/ml.

Carboplatin has been developed for clinical trials as a less nephrotoxic, less emetogenic analog of cisplatin. In preclinical tumor models it was less potent than the parent compound on a molar basis, but reduced toxicity allowed comparable antitumor doses to be given. In phase I studies its dose-limiting toxicities were reversible myelosuppression, especially thrombocytopenia. Leucopenia and anemia occurred to a lesser degree. Other reported toxicities included nausea, vomiting, malaise, myalgia, arthralgia, ototoxicity, hypomagnesemia, and proteinuria. Nausea and vomiting occurred frequently, but was much less severe than that observed with cisplatin. The incidence of serum creatinine elevations was low. The increase was usually reversible and occurred only in association with administration of aminoglycosides, or abnormal pretreatment renal function. Recommended phase II doses by schedule are: bolus every 4 weeks, 400-500 mg/m2 (560 mg/m2 in children); 24 hour continuous infusion every 4 weeks, 320-400 mg/m2; weekly bolus for 4 consecutive weeks with 2 weeks rest, 100-125 mg/m2 (175 mg/m2 in children); bolus for 5 consecutive days every 4 weeks, 77-95 mg/m2. Objective responses were observed during these phase I studies in adult patients (head and neck, breast, renal carcinomas) and children (osteosarcoma, brain stem lesions). In addition to phase II evaluations in all major tumor types, plans for phase III studies in selected tumors are underway.

The Phase I study of N-7-(p-hydroxyphenyl)-mitomycin C (KW 2083, M 83) was performed. The dose-limiting toxicity was leukopenia and thrombocytopenia and a maximum tolerable dose was 70 mg/m2. Nonhematologic toxicities included nausea (44%), vomiting (13%), diarrhea (2.7%), azotemia (8.1%), proteinuria (5.4%), alopecia (8.1%) and elevated hepatic enzymes (2.7%). This Phase I study indicates that the recommended starting dose for Phase II studies for patients without significant myelosuppression would be 50 mg/m2 at 6 week intervals in an intravenous push. KW 2083 should be avoided in patients with impaired renal functions and proteinuria because of permanent renal damages caused by the drug.

A phase I trial of diglycoaldehyde (Inox) in children with leukemia established that the maximum tolerated dose of a 5-day schedule was 1.5 g/m2/day. A phase II study was undertaken by the Children's Cancer Study Group to evaluate the efficacy of this dose. Forty-seven children with acute leukemia refractory to conventional forms of therapy were entered in the study: 29 patients with acute lymphocyte leukemia/acute undifferentiated leukemia and 18 with acute nonlymphocytic leukemia. Inox was administered at a dose of 1.5 g/m2 as a 4-6 hour iv infusion daily for 5 days every 14 days. Toxic effects included myelosuppression, proteinuria, nausea, vomiting, diarrhea, local tissue reactions, hypocalcemia, transitory serum amylase elevation, and transitory hypotension. There was one life-threatening episode of drug-related renal toxicity. Of the 27 patients who received a minimum of two courses, partial remissions were observed in two patients with acute nonlymphocytic leukemia. Inox was inactive against advanced acute lymphocytic leukemia.

We attempted to ascertain renal, hematologic, and neurologic tolerance to ifosfamide (IFX) in pediatric patients previously treated with large single and cumulative doses of cis-Diamminedichloroplatinum-II (CDP) for osteosarcoma (OS). Twenty OS patients were treated with CDP: initially 150 mg/m2 was administered every 2 weeks for a maximum of seven courses. Later, other agents, including additional CDP, were also administered. Twelve patients were treated with intra-arterial CDP, one with intra-arterial, and later intravenous CDP, and seven with intravenous CDP. Patients who relapsed were treated with IFX. Renal function was monitored by measuring creatinine clearance, serum electrolytes, total protein, albumin and CO2 content, and urine analysis during IFX therapy. Prior to initiation of IFX, creatinine clearance was above 60 ml/min/m2 in all except one patient who had developed a hemolytic uremic syndrome (HUS). Cumulative CDP doses ranged from 300 to 22,500 mg/m2, and cumulative IFX doses 12 to 128 gm/m2. Myelosuppression was monitored by obtaining routine hemograms midway between each course of treatment. Neurologic tolerance was assessed by reviewing the medical records for any abnormality. The interval between CDP and IFX ranged from 1 to 64 months. All patients experienced a progressive reduction in creatinine clearance with CDP. The reduction in creatinine clearance, measured from base-line after three to four courses varied from 10 to 53.7%, after four to seven courses from 19 to 78%, and after seven courses from 12 to 80.5%. In all patients except five, including the HUS patient, creatinine clearance remained above 60 ml/min/m2 during IFX therapy. Twelve patients developed hypo-magnesemia in the vicinity of 1.4 to 1.6 mg/dl during CDP treatment and required magnesium supplementation. They were asymptomatic and the abnormality did not affect IFX tolerance. Fourteen patients intermittently displayed variable degrees of glycosuria, phosphaturia, and/or proteinuria during IFX therapy. This was considered to be a forma frustre type of Fanconi's syndrome. Approximately 80% of courses of IFX were associated with reversible myelosuppression. No neurologic abnormalities were detected. The abnormalities detected during IFX treatment were not major, did not give rise to symptomatology, and did not require discontinuation of therapy. Renal abnormalities were considered a forma frustre type of Fanconi's syndrome. Provided a creatinine clearance of 60 ml/min/m2 is accepted as a prerequisite for treatment, and no major preexisting renal disease is present, IFX is well tolerated by most patients previously exposed to very high cumulative doses of CDP.

Since their initial description in 1957, the interferons (IFNs) have been increasingly used to treat a wide array of diseases. Acute adverse effects, i.e. 'flu-like' syndromes, hypo- or hypertension, tachycardia, headache, myalgias and gastrointestinal disorders, occur within the first hour or day after starting treatment. They are seldom treatment-limiting and are easily manageable. Sub-acute and chronic effects develop after several days, usually within 2 and 4 weeks of therapy. The most typical is neurological toxicity, including fatigue/asthenia, and behavioural and cognitive changes. Such symptoms may seriously impair quality of life and result in treatment discontinuation. Seizures have seldom been described. Other infrequent central nervous system adverse effects include vertigo, cramp and oculomotor nerve paralysis. Distal paraesthesias and peripheral neuropathy have been reported. IFN-associated autoimmunity is quite rare but a matter of concern. Biological or clinical manifestations usually require several months to become apparent. Autoantibodies have been shown to develop in most patients but have been inconsistently associated with clinical symptoms of systemic lupus erythematosus, rheumatoid-like arthritis and thyroiditis. Both hypo- and hyperthyroidism have been described but are usually reversible. Other infrequent autoimmune reactions include diabetes, pemphigus and worsening of multiple sclerosis. Although several patients present with a pre-existing autoimmune disorder, no predisposing factor has been clearly established. While hypotension and tachycardia are the most frequent acute cardiovascular complications, a few additional cases of cardiac arrhythmias and myocardial ischaemia have been reported after a short course or several weeks of treatment. These latter complications do not appear to be dose-dependent or age-related. Isolated cases of congestive heart failure have also been described. Mild proteinuria has been observed in 15 to 25% of patients, but acute renal toxicity is uncommon. A transient rise in serum aminotransferase levels is frequently noted during the first stage of therapy, especially in patients receiving the highest dosages. Direct hepatotoxicity is extremely rare. Autoimmune hepatitis, which is ill-diagnosed as chronic viral hepatitis, and de novo induction of autoimmune hepatitis, account for the majority of liver diseases. Haematotoxicity is relatively common but mild to moderate, and develops gradually during the first weeks of treatment. Neutropenia is the most common haematological toxicity, but is usually not dose-limiting and resolves rapidly upon drug discontinuation. Myelosuppression, autoimmune and immune allergic haemolytic anaemias and thrombocytopenias have seldom been described. Cutaneous adverse effects comprised nonspecific erythema and hair loss and, less frequently, vasculitis, local ulcerations at the site of injection and exacerbation of psoriasis.(ABSTRACT TRUNCATED AT 250 WORDS)
