Phase I study of monoclonal antibody-ricin A chain immunoconjugate Xomazyme-791 in patients with metastatic colon cancer.

The immunoconjugate XMMCO-791/RTA consists of ricin A chain bound to a murine monoclonal antibody MoAb 791T. This monoclonal antibody (MoAb) binds to a glycoprotein of 72 kD, which is expressed on human colorectal carcinoma, ovarian carcinoma, and osteogenic sarcoma. XMMCO-791/RTA was tested in a Phase I trial with proposed dose escalation steps of 0.

Treatment of osteoarthritis of the knee. A comparison of flurbiprofen and aspirin.

The analgesic efficacy of flurbiprofen (Ansaid, Upjohn) and aspirin were compared in a 12-week, double-blind, randomized, parallel, multicenter study of 147 patients with osteoarthritis of the knee. Flurbiprofen (73 patients) was administered two, three, or four times a day in total daily doses of 100, 150, or 200 mg; aspirin (74 patients) was also given two, three, or four times a day in total daily doses of 2,000, 3,000, or 4,000 mg. Flurbiprofen was found effective in controlling pain and other symptoms of osteoarthritis.

Flurbiprofen in the treatment of rheumatoid arthritis. A comparison with aspirin.

This large-scale, double-blind study compared 200 mg per day of flurbiprofen (Ansaid, Upjohn) with 4,000 mg per day of aspirin in 822 patients with definite or classical rheumatoid arthritis who were evaluated for up to 52 weeks. Overall response to therapy was similar in both groups. By the end of the study, however, significantly more patients remained in the flurbiprofen (54 percent) than in the aspirin group (40 percent).

Safety of flurbiprofen in the treatment of ankylosing spondylitis, osteoarthritis, and rheumatoid arthritis. A summary of liver and kidney assay data.

The safety of flurbiprofen (Ansaid, Upjohn) was assessed after pooling data on kidney and liver function collected from nine separate phase III clinical trials involving 1,677 patients (941 receiving flurbiprofen and 736 receiving comparison drugs) with ankylosing spondylitis, osteoarthritis, or rheumatoid arthritis. Multiple categories were created to discern the effects of treatment, disease, age (under 60 and 60 years or older), and duration of exposure to flurbiprofen. No clinically significant trends in kidney or liver function were detected in any category following the administration of flurbiprofen.

Flurbiprofen in the treatment of acute gout. A comparison with indomethacin.

The relative efficacy and safety of flurbiprofen (Ansaid, Upjohn) and indomethacin were compared in 29 patients with monoarticular gouty arthritis of less than 48 hours' duration. A loading dose of 400 mg of flurbiprofen or 200 mg of indomethacin was administered for 24 hours, followed by 200 mg of flurbiprofen per day or 100 mg of indomethacin per day for a maximum of five days. Based on global assessment of improvement, at least 50 percent of patients in both treatment groups showed improvement within 24 hours.
