Aspoxicillin (ASPC), a new penicillin for injection, was evaluated for its efficacy and safety in 29 children with bacterial infection (Table 1), and the following results were obtained. MICs of ASPC to 26 strains of isolated organisms are shown in Table 2. MICs to 4 out of 13 strains of H. influenzae were higher than 6.25 micrograms/ml. MICs to 5 strains of S. pneumoniae were lower than 0.78 microgram/ml and 1 out of 3 strains of S. aureus and 1 strain of E. coli showed higher MICs than 100 micrograms/ml. ASPC was administered in 3 or 4 divided doses at a daily dosage ranging from 21 to 98 mg/kg by 30 minutes drip infusion or intravenous injection to 29 patients (16 cases of pneumonia, 8 cases of tonsillitis, 3 cases of bronchitis, 1 case of urinary tract infection, 1 case of impetigo) and the following clinical results were obtained: excellent; 11 cases, good; 11 cases, fair; 3 cases, poor; 1 case. The overall efficacy rate was 85% (Table 3, 4). No clinical side-effects were observed in any of the patients. Leukopenia was noted in 1 case. Slight elevation of GOT and GPT was noted in 2 cases, and minimal elevation of GOT was observed in other 2 cases (Table 5). These data suggest that ASPC is an useful new antibiotic in the treatment of children with susceptible bacterial infection and may be used as the first choice antibiotic for the treatment of respiratory tract infection in children.

A phase II study of recombinant interferon alpha A (Ro 22-8181) for malignant brain tumors was jointly conducted at 21 medical institutes in order to evaluate its clinical effects and side effects. Treatment started with exclusive administration of Ro 22-8181 at 3 X 10(6) U/day, which was increased appropriately after confirmation of its safety, until an optimum dose permitting long-term administration was achieved for each patient. The dose thus determined was intramuscularly administered daily. Among those treated, 39 patients were available for evaluation. The percentage of partial responses according to the "Criteria for the Evaluation of Clinical Effects of Cancer Chemotherapy on Solid Tumor" by Koyama and Saito was 10.3% (4/39). Histologically, this was 7.1% (1/14) for glioblastoma and 14.3% (3/21) for malignant astrocytoma. Side effects included fever (57.3%), anorexia (34.1%), general fatigue (31.7%), leukopenia (52.4%) and thrombocytopenia (30.5%), and increased GOT and GPT (40.2%). In view of the success even in previously treated patients, and the side effects observed, Ro 22-8181 may be accepted as a useful addition to the treatment of malignant brain tumors.

A cooperative study was carried out in 32 institutions throughout the country to evaluate the clinical efficacy of recombinant human leukocyte A interferon (rIFN-alpha A, Ro 22-8181) on malignant tumors of the urogenital tract. The responses were evaluated according to the "Criteria for the Evaluation of Clinical Effects of Cancer Chemotherapy on Solid Tumor" proposed by Koyama and Saito. Out of 269 cases which were examined in the present study, 138 cases were evaluable. Among 108 cases with renal cell carcinoma, efficacy was observed in 15 cases; complete response (CR) in 2 cases and partial response (PR) in 13 cases, indicating an efficacy rate of 13.9%. PR was obtained in 1 case out of 14 with bladder cancer and 1 case out of 6 with tumors of the renal pelvis and ureter. Main subjective and objective adverse reactions observed were fever, malaise, anorexia and nausea and/or vomiting. Laboratory test abnormalities consisted of leukopenia, thrombocytopenia and elevation of GOT X GPT. All of these disappeared with discontinuation of rIFN-alpha A or after administration of its therapeutic dose.

A Phase II study of recombinant leukocyte A interferon (rIFN-alpha A, Ro 22-8181) was performed in 121 patients with hematological malignancies at 33 institutions from July, 1982 to May, 1984. Patients received Ro 22-8181 by intramuscular injection daily for more than 4 weeks. Daily doses were escalated from 3 X 10(6) to 6X, 9X, 18X, 36X and 50X 10(6) units every 3-7 days. Among 70 evaluable cases, complete or partial responses were observed in 15 patients (21.4%). One complete and 10 partial responses (22.4%) were noted in 49 cases of multiple myeloma, 2 partial remissions (18.2%) in 11 cases of malignant lymphoma and 2 partial remissions (25.0%) in 8 cases of leukemia. Side effects included fever (57.0%), anorexia (34.2%), nausea-vomiting (22.8%), malaise (19.0%), leukopenia (44.3%), thrombocytopenia (45.6%) and increase of GOT or GPT (26.6% or 22.8%). They were all not serious and disappeared quickly after the discontinuation of Ro 22-8181.

A healthy twenty-month-old boy ingested a maximal dose of valproate from which about 750 mg/kg were absorbed. Cerebral coma, which lasted for twenty hrs, was followed by an undisturbed period of approximately sixteen hrs. Death from cardiorespiratory failure due to severe bronchopneumonia occurred 46.5 hrs after the ingestion of the drug. The serum valproic acid concentration reached a peak of 1061 micrograms/ml within three hours, and fifteen minutes before death it had fallen to 187 micrograms/ml. The half-life of 16.6 hrs was within the range usually found. Metabolic acidosis, hypernatraemia and hyperosmolarity could be corrected, unlike the hypocalcaemia, which developed later. Bilirubin, GOT, GPT, gamma-GT, alkaline phosphatase, blood glucose, diastase, urea, creatinine, haemoglobin as well as PT and PTT and the platelet count were all normal. Leucopenia with 1,600 per microliter developed only during the bronchopneumonial stage. The histo-pathological findings were acute hypoxic damage of the myocardium, kidneys and certain neurones of vulnerable areas of the brain (neuronal microvesiculation and tigrolysis) in addition to a severe cerebral oedema in the final stage. A morphological substrate of an acute valproate encephalopathy was not demonstrable. The liver showed no necrosis or cholostasis. The vertebral marrow was inconspicuous. All the results indicate that liver function was not impaired in spite of the initial maximal concentration of valproic acid. In all probability the patient might have survived the acute valproate intoxication had it not been for the bronchopneumonia.

A clinical Phase I study of recombinant human interferon alpha A (Ro 22-8181) was performed in patients with malignant tumors; twenty of them received an American product and seven others a domestic product. Both products were administered in single intramuscularly injected doses of 18, 36, 50, 75 and 100 X 10(6)U. Main side effects included fever and influenza-like symptoms (headache, chill/shivering, general fatigue, lumbago), and digestive symptoms (anorexia, nausea/vomiting). Numbness of fingers or limbs and somnolence were also observed in higher dose groups, but these symptoms all disappeared on the day of administration or by the 3rd day after administration. Abnormal laboratory findings included leukopenia, granulocytopenia, lymphocytopenia, thrombocytopenia and increased GOT/GPT/LDH, but these returned to normal by the 10th day after administration. The peak blood concentration was correlated with the dose, falling to the base line 72 hr after administration. The American product and the domestic product were nearly comparable in the type and incidence of their side effects, and also produced generally comparable blood concentrations. Furthermore, increased anti-IFN-alpha antibody titer was not observed in any of the patients; and the Prick Test proved negative in all of them. No significant changes were observed in any immunological parameters, either.

A phase II study on recombinant human leukocyte A interferon (rIFN-alpha A) was carried out in 30 patients with urogenital cancers. Each patient received rIFN-alpha A by i.m. injection every day for at least 4 weeks. The initial daily dose was 3 X 10(6) U, being escalated at intervals of 3 days or more up to 50 X 10(6) U. The results are summarized as follows: In aged patients, the daily dose appropriate for everyday i.m. injection was considered to be 9 X 10(6) U or below, judging from the adverse reactions observed. According to Koyama and Saito's response criteria, partial response (PR) and minor response (MR) were obtained, respectively, in 3 and 1 out of 12 patients with renal cell carcinoma, while PR was seen in 1 out of 9 with urothelial cancer. No response was observed in patients with testicular cancer and in those with prostatic cancer. Various kinds of adverse reactions were recognized and each patient showed one reaction or more. Fever, fatigue, leukopenia, anemia, thrombocytopenia and elevation of GOT and GPT were observed relatively frequently. Among these, fatigue and thrombocytopenia were regarded as dose limiting factors.

Recombinant human leukocyte (alpha) interferon was administered i.m. at the initial dose of 3 X 10(6) U/day to 27 patients with measurable metastatic renal cell carcinoma during the past 2 years. The results of 22 of these patients were evaluable. Three patients (13.6%) showed partial response; 3 patients (13.6%), minor response; 7 patients (31.8%), no change; and 9 patients (40.9%), progressive disease. Major toxicity consisted of fever (55.5%), anorexia (44.4%), malaise (22.2%), elevation of GOT/GPT (48.1%), leukopenia (44.4%) and thrombocytopenia (29.6%). When the 3 patients who showed stabilization (S) and the 2 patients who showed mixed effects (ME) among the 7 patients who showed no change are classified into the responded group, half the patients had some response to interferon. Characteristics of these responders (PR + MR + ME + S) were good performance status, relatively longer disease-free interval, metastases limited to the lungs or metastasis to lungs and one other organ excluding the liver, and frequency of interferon-induced thrombocytopenia. Interferon administration is still being continued to 4 patients on an outpatient basis, 5 patients are hospitalized and 13 patients have died. In conclusion, patients with pulmonary metastases seem to be the best responding group for interferon treatment in renal cell carcinoma and further trials, especially combined regimens with chemotherapy and/or other kinds of interferon should be tested.

A multicenter cooperative clinical trial was carried out on S6472 (a long-acting preparation of cefaclor (CCL)) to evaluate its effectiveness and safety in the treatment of infectious diseases in the field of otorhinolaryngology. The results are as follows: The clinical efficacy of the drug could be evaluated in 114 patients. An efficacy rate of 65.8% was obtained. The efficacy rate for each disease was found to be 60.0% for acute suppurative otitis media, 12.5% for chronic suppurative otitis media and 44.4% for acute exacerbation of chronic suppurative otitis media. The overall efficacy rate for all cases of suppurative otitis media was 46.4%. The efficacy rate for acute tonsillitis was found to be 93.1%. In the treatment of acute exacerbation of chronic tonsillitis, the efficacy of the drug was rated as excellent or good in all cases. The overall efficacy rate for all cases of tonsillitis was found to be 93.9%. In the treatment of other infectious diseases, the efficacy was rated as excellent or good in all cases. When the cases by resistant organisms to CCL were excluded from the evaluation, the overall efficacy rate of the drug was found to be 74.2%. The bacteria could be identified in 106 cases. Regarding the bacteriological efficacy of single infections, its bacterial elimination rate was found to be 81.1% for Gram-positive bacteria including S. aureus, S. epidermidis, etc., while it was 42.9% for Gram-negative bacteria. The overall elimination rate of bacteria in single infections was 73.1%. The bacterial elimination rate for mixed infections was found to be 85.7%, whereas it was 76.8% when the single and mixed infections were combined. Regarding side effects, 1 case each of diarrhea, soft stool and rash, or 3 cases in total (2.4%), were recorded in a total of 123 patients. However, the severity of each side effect was mild. Regarding abnormal laboratory findings, there were 1 case each of an increase in S-GPT, leukopenia and complication of eosinophilia and thrombocytopenia, or 3 cases in total (7.0%). Each of these adverse reactions was, however, transient in nature, and no serious cases were observed. On the basis of the above results, it was concluded that S6472 can provide sufficient clinical efficacy when it is administered at daily dosage of 750 mg or 1,500 mg in 2 divided doses after the breakfast and dinner.

Cefotaxime (CTX) was microbiologically and clinically studied in surgery. CTX shows excellent antibacterial activity in vitro against Gram-negative bacilli including E. coli. Klebsiella spp., and Proteus spp. in comparison with cefmetazole (CMZ) and cefazolin (CEZ). Antibacterial activity of CTX is found to be superior to that of CEZ and equal to that of CMZ against Gram-positive bacteria (S. aureus and S. epidermidis). The antibacterial activity of CTX against anaerobic bacteria exceeds that of CEZ and almost equal to that of CMZ. It also showed minimum inhibitory concentration values which, clinically speaking, offer great expectation. CTX is also superior to CMZ and CEZ in its antibacterial activity against P. aeruginosa. Clinical studies were carried out in the group A for which CTX was administered a drug of first choice for postoperative infections in surgery, and in the group B for which CTX was administered as a drug of second choice since the antibiotic of first choice had been ineffective for these cases. As a result, high effective rates were obtained in both groups (80.3% for the group A, and 77.1% for the group B). With reference to the group B, an effectiveness rate of 100% was obtained for the cases in which CEZ had been ineffective and 55.6% was obtained for 10 cases in which mainly combination of CMZ had been ineffective. Side effects appeared in 3 cases (1 case each of tinnitus and malaise, vomiting and nausea, and fever) with an incidence rate of 1.46%. Abnormal clinical laboratory findings appeared in 4 cases (1 case each of leukopenia and increase in GOT and GPT; eosinophilia; increases in platelet and monocyte; and increases in GOT, GPT and A1-P) with an incidence rate of 1.95%.
