Summary

RATIONALE:

The integrity of the intestinal mucosa is a key factor for the preservation of a normal gut function. Damage of the epithelium (i.e. by chemotherapy) results in significant cellular and molecular alterations that ultimately lead to intestinal dysfunction/failure. This intestinal dysfunction manifests as several pathological processes, such as inability to absorb nutrients, intestinal inflammation, immune system dysregulation, and disequilibrium of normal intestinal microbiota leading to increased risk of infection due to bacterial translocation and septicaemia. Gastrointestinal (GI) mucositis is a well-known, frequent and debilitating side effect of most anticancer regimens with a very high incidence in hemato-oncology. The most common symptoms are nausea, vomiting, weight loss, abdominal cramps and pain, diarrhea, and electrolyte imbalance. Patients may also experience ulceration/bleeding and injury of the lining of the entire gastrointestinal tract from the esophagus to the colon. Currently no therapy is available for the prevention or treatment of GI intestinal injury. Treatment of related symptoms is limited to supportive measures to decrease diarrhea and to preventive antibiotic therapy. The GLP-2 analogue, FE 203799, has a favorable pharmacology profile for clinical development in the intended therapeutic indication of myeloablative chemotherapy-induced GI damage. The data collected from animal studies has shown that FE 203799 stimulates the proliferation of the intestinal epithelium and protects the GI mucosa from chemotherapy-induced injury. Hence, the primary pharmacologic activity of FE 203799 would promote a healthy GI microenvironment, thus preventing intestinal dysfunction and related complications.

PURPOSE: Prevention by FE 203799 of chemotherapy-induced intestinal damage and related complications in patients with lymphoma receiving Melphalan based (BEAM) myeloablative conditioning regimen followed by hematopoietic stem cell transplantation.

Criteria

Inclusion Criteria:

12. Patients must have recovered from the effects of any prior chemotherapy, radiotherapy or surgery; for patients who have been on monoclonal antibody therapy, at least one half-life or 4 weeks (whichever is longer) should have elapsed prior to the first scheduled day of dosing with FE 203799.

13. A female recipient of childbearing potential must meet the following criteria:

1. Participant has a negative pregnancy test at Screening.

2. Participant agrees to use one of the accepted contraceptive regimens from at least 14 days prior to the first administration of the Study Drug, during the study and for at least 90 days after the last dose of the Study Drug. An acceptable method of contraception includes one of the following:

• Abstinence from heterosexual intercourse

• Systemic contraceptives (birth control pills, injectable/implant/insertable hormonal birth control products, transdermal patch)

• Intrauterine device (with or without hormones)

• Diaphragm with spermicidal gel

• Condom with spermicide gel

14. A male patient, with sexual partners who are pregnant, possibly pregnant, or who could become pregnant, agrees to use one of the accepted contraceptive regimens throughout the entire duration of the study and until at least 3 months after the last drug administration. An acceptable method of contraception includes one of the following:

• Abstinence from heterosexual intercourse

• Condom with spermicide

Exclusion Criteria:

1. Patient is unable or unwilling to give informed consent.

2. Patients who are unable to comply with the treatment protocol including appropriate supportive care, follow-up and tests.
