Clinical applications of <[censored]> peptides

One prospective randomised study in patients with malignant melanoma, thymus peptides caused an increased tumour-free period, a longer survival time and increased quality of life (4). One prospective, randomised study in intermediate- and high-grade Non-Hodgkin?fs lymphoma, patients were treated with thymus peptides in addition to standard chemotherapy. The treated patients tolerated thymus peptides quite well and had a significantly higher complete response rate than those patients who did not receive thymus peptides (5). One prospective, randomised study in patients undergoing colorectal surgery showed, that the patients, who received thymus peptides in addition to Cefotetan, did significantly better in lowering the rate of abdominal abscesses and upper respiratory tract infections (6). One prospective, randomised study in women with advanced breast cancer could document, that those women, receiving thymus peptides in addition to their chemotherapy regimen, tolerated the chemotherapy significantly better and reduced the rate of secondary infections (7,8). One prospective, randomised study in breast cancer patients showed that thymus peptides protect the bone marrow functions against the haematological toxicities and recovery during and after high dose of Mitoxantrone (9). Another study also showed significant benefit in complete response rate to therapy and prevention of myelosuppression and secondary infections when thymus peptides were added to the regimen (10,11). Therefore, in the Cologne Model, thymus peptides are used:

1) To enhance bone marrow function and protect the patient against myelosuppression of standard chemotherapy;
2) To support bone marrow recovery after radiation and chemotherapy;
3) To prevent secondary infections due to immunosuppression caused by standard chemotherapy and surgical interventions;
4 )To increase complete and partial response rate to anticancer therapies;
5) To improve lymphocyte function and biological defence mechanisms.
