A Phase I study was carried out with ricin, a plant toxin acting by inhibiting protein synthesis, on 54 cancer patients with advanced disease. Ricin was given as i.v. bolus injections every two weeks at dose levels ranging from 4.5 to 23 micrograms/sq m of estimated body surface area. Ricin was well
OBJECTIVE
Ricin-mAb35 is an immunotoxin targeted against skeletal muscle. Previously, we have shown that injection of ricin-mAb35 into rabbit extraocular muscle results in long-term muscle loss, and we have proposed this as a potential treatment for strabismus. In this study, we assessed the effects
To determine the maximally tolerated dose of a ricin A chain-conjugated antimelanoma antibody (XomaZyme-Mel), 20 patients with metastatic melanoma were treated with escalating doses of the murine immunotoxin given as single intravenous infusion over 30 minutes. The starting dose was 0.6 mg/kg and
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
This Phase II trial was undertaken to determine the safety, toxicity, and potential efficacy of the B-cell restricted immunotoxin anti-B4-blocked ricin (Anti-B4-bR) when administered as adjuvant therapy to patients in complete remission (CR) after autologous bone marrow transplantation (ABMT) for
We conducted a trial of a murine monoclonal antimelanoma antibody-ricin A chain immunotoxin (XOMAZYME-MEL) in 22 patients with metastatic malignant melanoma. The dose of immunotoxin administered ranged from 0.01 mg/kg daily for 5 days to 1 mg/kg daily for 4 days (total dose: 3.2 to 300 mg). Side
Acute steroid-resistant graft-versus-host disease (AGVHD) after allogeneic bone marrow transplantation is frequently fatal. A new treatment for this T-lymphocyte-mediated condition uses an immunotoxin, H65-RTA, comprised of a monoclonal antibody that recognizes the CD5 lymphocyte differentiation
Since MRD is the major cause for relapses of malignant diseases, strategies utilizing ITs to target tumor cells surviving conventional treatment have attracted scientific and clinical interest. Many different ITs against various blood-borne as well as solid malignancies have demonstrated specific
H65-RTA is an immunoconjugate that consists of the A chain of ricin (RTA), a ribosomal-inhibiting protein, coupled to a murine monoclonal antibody (H65) directed against the pan-T-cell antigen CD5. The CD5 antigen is heterogeneously expressed on cutaneous T-cell lymphoma tumor cells, but is not
