Phase I Non-Myeloablative Trial With 90Y-Humanized MN-14 (Anti-CEA) Antibody for Relapsed or Refractory Small Cell Lung Cancer (SCLC)
- Determine the dose limiting toxicity and maximum tolerated dose of yttrium Y 90
anti-CEA monoclonal antibody MN-14 in patients with relapsed or refractory small cell
- Determine the dosimetric and pharmacokinetic properties of this treatment regimen in
the blood, normal organs, and tumors of these patients.
- Determine the stability and complexation with circulating carcinoembryonic antigen of
this radioantibody in the plasma of these patients.
- Determine the antibody response of these patients treated with this regimen.
- Determine the antitumor effects of this treatment regimen in these patients.
OUTLINE: This is a dose escalation study of yttrium Y 90 anti-CEA monoclonal antibody MN-14
(90Y-hMN-14). Patients are stratified according to prior radiotherapy (yes vs no).
Patients undergo pretherapy imaging with indium In 111 anti-CEA monoclonal antibody MN-14 IV
over 30-40 minutes on day -7 or -6 followed by external scintigraphy on days -7 or -6 to 0.
Patients who show positive localization of at least one documented tumor site receive
90Y-hMN-14 IV over 30-40 minutes on day 0.
Cohorts of 3-6 patients receive escalating doses of 90Y-hMN-14 until the maximum tolerated
dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2
of 3 or 2 of 6 patients experience dose limiting toxicity.
Patients are followed at 2, 4, 8, and 12 weeks; every 3 months for 2 years; and then every 6
months for 3 years.
PROJECTED ACCRUAL: A total of 15-30 patients will be accrued for this study within 10-14
Primary Purpose: Treatment
