A Phase 1/2 Study With BM7PE Immunotoxin in Colorectal Cancer Patients With Metastatic Disease Who Are Refractory to or With Intolerance to Last Line of Standard Chemotherapy.

This phase 1/2 study will evaluate the safety, tolerance and dose of BM7PE treating patients with colorectal cancer who have progressed to standard cell therapy or cannot tolerate such therapy. The study starts as a phase 1 study with the aim of assessing the final dose for this group of patients. Based on the results, the study will continue into a phase 2. The phase 2 study aim to examine overall survival ≥ 9.3 months.

Adjuvant chemotherapy in breast cancer patients has had limited success, which is possibly because of lack of effect on non-proliferating cells accompanied by the emergence of drug-resistant cell clones. Since immunotoxins (ITs) are known to exert proliferation-independent cytotoxicity, we investigated the efficacy of systemically administered anti-carcinoma ITs in nude rat models, simulating micrometastatic disease. The monoclonal antibodies MOC31, BM7 and 425.3, which recognize epithelial glycoprotein 2, MUC-1 mucin and the epidermal growth factor receptor, chemically conjugated to Pseudomonas exotoxin A (PE), inhibited protein synthesis of the 2 breast cancer cell lines at concentrations of 0.3-0.4 ng/ml, except for BM7-PE, which was less efficacious (65 ng/ml). In the MA-11 model in nude rats, a single i. v. dose of 20 microg MOC31-PE prevented development of metastasis in the spinal cord in 11/19 (58%) of the animals. Similarly, 425.3-PE treatment gave 6/9 (66%) long-term survivors. In rats injected intracardially or intratibially with MT-1 cells, treatment with 425. 3-PE prevented metastasis in 4/10 (40%) and intratibial tumor growth in 17/18 (94%) of the rats. Importantly, an equimolar dose of free 425.3 (antibody) was ineffective, whereas PE alone was toxic. With BM7-PE, 5/17 (29%) cures were obtained in the intratibial model. The results demonstrate that systemic short-term treatment with non-toxic doses of the 3 ITs tested can effectively inhibit the development of experimental breast cancer metastasis and/or local tumor growth in bone. The results support the development of the ITs towards clinical evaluation for possible use as short-term adjuvant therapy in patients at high risk of early relapse.
