One hundred thirty-eight adults with advanced cancers were treated with Baker's Antifol. The complete response + partial response rate was only 10%. Best responses were obtained in 31 patients with lung adenocarcinoma (complete response + partial response, 13%), in 25 patients with colorectal carcinoma (partial response, 16%), and in 6 patients with renal cell carcinoma (partial response, 50%). Two partial responses occurred in 15 patients with squamous cancer. No significant responses were seen in 27 patients with other adenocarcinomas, 13 with sarcomas, 14 with melanomas, and 8 with miscellaneous tumors. The most frequent toxicities were dermatitis, stomatitis, gastrointestinal symptoms, and mild myelosuppression. The incidence of dermatitis was significantly decreased by shortening the schedule of Baker's Antifol administration from 5 to 3 days. Baker's Antifol has some degree of antitumor activity, and studies of combination of this agent with other effective chemotherapeutic agents are indicated.

Triazinate (Baker's Antifol, NSC 139105) was given to 28 patients as a single agent in the chemotherapy of advanced colerectal carcinoma. The dosage utilized was 250 mg/m2 intravenously, administered daily in three consecutive days. Patients were evaluated at three weeks, six weeks, and then monthly until progression was evident. Various immunologic determinants (i.e., DNCB sensitization, immunoglobulins, recall skin tests, lymphocyte blastogenesis, and circulating lymphocytes, T-cells and B-cells) were obtained prior to treatment and at each re-evaluation. The principal side effects were dermatitis, stomatitis, diarrhea, nausea, somnolence, and leukopenia. There was no discernable effect of Triazinate on the immunologic determinants tested. There was one complete response, and four partial responses, for an objective regression rate of 18%. This study suggests that Triazinate has a definite, though limited, effect on advanced colorectal carcinoma.

Gonadal and other types of leukemic "sanctuaries" are probably the main causes of hematological relapse in the treatment of acute leukemia. The introduction of high-dose Methotrexate (HDM) in a consolidation phase is based on theoretical considerations and the use of HDM in malignant tumors. Three courses of Methotrexate, 500 mg/sq.m. at 3-weekly intervals, has been used as part of a consolidation therapy in Norway during the last two years to 59 children with ALL and one with AML. One child died following HDM. Postmortem examination showed that she was not in complete remission at the time. Among 154 courses of HDM in the 60 patients were eight severe reactions, including six cases of allergic-toxic skin reactions. Two patients developed a Stevens-Johnson's like syndrome. Stomatitis was common in those with toxic reactions. The risk of HDM in patients who are not in complete remission is stressed and the use of rescue therapy with two doses of Leukovorin instead of one is recommended. Forty of forty-two children in 1st complete remission have been in sustained primary remission for 4 to 28 months. Two of these 40 children died after about a year from infections. Only two patients so far have relapsed.

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.

Pyrazofurin was administered to 17 patients with refractory acute myelogenous leukemia in 5-day courses every 2-3 weeks. Doses ranged from 30 to 60 mg/m2/day. Severe stomatitis and dermatitis occurred at doses effective in reducing the leukocyte count (45 mg/m2). Reduction of the dose to 30 mg/m2 resulted in less toxicity and less chemotherapeutic effect. These results indicate that at tolerable doses given as described, pyrazofurin had little antileukemic activity in acute myeologenous leukemia.

A Phase I clinical trial of N-(phosphonacetyl)-L-aspartate, an antimetabolite which inhibits a key enzyme in the de novo pathway of pyrimidine biosynthesis, was conducted. N-(Phosphonacetyl)-L-aspartate was given as an i.v. 15-min infusion once daily for five days; cycles of treatment were repeated every three weeks. Thirty-four patients received treatment. Dose-limiting toxicity was observed at 1500 to 2000 mg/sq m/day and was manifested by skin rash, diarrhea, and stomatitis. Rash and diarrhea usually began during the first week of treatment and persisted up to Day 17 of a cycle of therapy. No consistent hematopoietic, hepatic, or renal toxicity was observed. One partial response in a patient with colon carcinoma was seen and continues at more than eight months. Stable disease was observed in three patients with colon carcinoma, two patients with hypernephroma, one patient with pancreatic carcinoma, and one patient with melanoma. The predictability and reversibility of toxicity and the suggestion of antitumor activity in humans are observations which support the further evaluation of N-(phosphonacetyl)-L-aspartate in Phase II studies.

Pyrazofurin was administered to 21 patients with solid tumors at a dose of 200 mg/m2 iv weekly, because this dose had been shown to be well-tolerated and pharmacologic effects of a single dose at this level persisted for up to 7 days. An anemia consistent with a disturbance in rbc production was seen in most patients. Other toxic effects included stomatitis, rash, and myelosuppression. No complete or partial responses were noted, but two patients with alveolar cell carcinoma of the lung each had stable disease for 12 months. Most of the patients in this study tolerated the weekly dosage schedule well with only minimal myelosuppression, suggesting that this agent and schedule might be acceptable for use in combination chemotherapy. Several theoretic reasons favor the use of pyrazofurin in this manner. Pyrazofurin should also be evaluated more fully in patients with polycythemia vera, mycosis fungoides, and psoriasis, since other orotidylate decarboxylase inhibitors have been shown to be effective in these diseases.

The complementation properties of the virus progeny released from cells mixedly infected with mutants of vesicular stomatitis virus belonging to four different complementation groups have been examined. The group IV mutant, tsW16B, was tested in combinations with three group I mutants (tsW4, tsW28, and tsG11), one group II mutant (tsG22), and one group III mutant (tsW29). Virus stocks were grown from isolated plaques appearing on the cell monolayers used to assay the mixed infection yields and tested, in a second series of mixed infections, for their ability to complement each of the two parents. It was found that the virus harvested from each one of the first series of mixed infections contained mutants of both parental types.

A group of RNA viruses, echovirus, poliovirus, reovirus, respiratory syncytial virus and Semliki Forest virus have been examined for ability to grow in enucleate African green monkey kidney (BSCi) cells. Semliki Forest virus produced an almost normal yield of virus but poliovirus, echovirus, reovirus and respiratory syncytial virus, although showing clear evidence of virus replication when compared with a nuclear DNA virus (pseudorabies virus) gave much lower yields than those from nucleate cells. Analysis of enucleate cells infected with echovirus and reovirus showed no evidence of a specific block in the synthesis of any virus-specified polypeptide. Infection with vesicular stomatitis virus at intervals after enucleation demonstrated a diminishing ability to support virus growth with increasing time. It is suggested that the yield of virus obtained from an enucleate cell is related to the length of the growth cycle of the virus, the reduced yield obtained with some viruses reflecting the declining ability of the enucleate cell to support virus growth.

Pseudotypes of vesicular stomatitis virus were prepared with avian sarcoma viruses and avian leukemia viruses representing five different subgroups. These pseudotypes display a host range restricted to that of the avian tumor virus when assayed on avian cells and are neutralized by subgroup-specific antisera. The efficiency of penetration of mammalian cells was assayed by using these vesicular stomatitis virus pseudotypes. Pseudotypes of avian tumor viruses belonging to subgroup D and of B77 virus were able to plate on mammalian cells with a high efficiency, whereas pseudotypes of other strains were not. The efficiency of penetration of the vesicular stomatitis virus pseudotypes was 10-2-to 10-3-fold higher than the efficiency of transformation of the corresponding avian tumor virus strain assayed on mammalian cells, suggesting that there are postpenetration blocks to the expression of transformation in these cells.
