Clinical Trial Summary

In this alpha-radioimmunotherapy study groups of 3 patients with recurring epithelial ovarian cancer treated by salvage chemo-therapy and being in complete or good partial remission will receive one intra peritoneal infusion of 211 astatine (211At)-MX35 F(ab')2 . Patients will receive a single dose of MX35 F(ab')2 radiolabeled with increasing activity concentration of 211At in 1.0 - 2 L Extraneal® solution starting at an activity concentration of 50 megabecquerel per litre (MBq/L).

Description:

• Five days prior to therapy the patient is provided with a central intra venous line and an abdominal catheter will be introduced during laparoscopy. To investigate the access to the whole abdominal cavity and possible catheter leakage, a 99mTc-colloid, will be infused intra peritoneally (IP) within 1.0 L of a gluco-polymer (Extraneal®).

• At the day of treatment vital signs will be measured prior to and after the 30 min infusion and at least every second hour during the first 6 hours after infusion, daily for the remainder of the in-hospital stay and at a minimum at 2, 3, 4 and 8 weeks after the IP infusion. Blood samples will be obtained for pharmacokinetic analyses every hour after completion of the IP infusion for 8 hours, then every 6 hours, together with sampling from the i.p. catheter.

• SPECT imaging of the whole abdominal cavity and thorax including the thyroid may be performed following completion of the IP infusion and at approx 8 or 20hrs post infusion.

• Physical examination and electrocardiogram will be done prior to and 4 weeks after the IP infusion. Clinical biochemical and hematological parameters will be monitored weekly after treatment. Blood samples to evaluate immunogenicity as well as cancer antigen-125 (CA-125) will also be taken at 2 and 8 weeks after treatment.

• The first patient will be observed for at least 4 weeks with any observed toxicity is Grade 2 or less, before the additional patient is accrued at the dose level.

• Dosimetry safety criteria: Based upon published data on maximal tolerated absorbed dose (Gy) recalculated to equivalent dose (Sv) with the assumption that the relative biological effectiveness (RBE) = 5, a limit for organ doses is defined. If any organ would reach the defined limit the study will be stopped.
