About

RATIONALE: Monoclonal antibodies, such as BB-10901, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them.

PURPOSE: This phase I trial is studying the side effects and best dose of BB-10901 in treating patients with relapsed or refractory solid tumors.

Full description

OBJECTIVES:

Primary

Determine the safety and tolerability of BB-10901
Determine the maximum tolerated dose of this drug in these patients.

Secondary

Determine the pharmacokinetics of this drug in these patients.
Determine the efficacy of this drug in these patients.

OUTLINE: This is an open-label, multicenter, dose-escalation study.

Patients receive BB-10901 IV over 40 minutes once daily on days 1-3.* Treatment repeats every 21 days

NOTE: *Patients who do not tolerate 3 consecutive daily infusions of BB-10901 may receive infusions of BB-10901 on 3 alternate days, upon approval by the investigator and/or the independent Safety Review Board.

Cohorts of 4-6 patients receive escalating doses of BB-10901 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 4-6 patients experience dose-limiting toxicity in course 1. Up to 40 patients are treated at the MTD.

After completion of study treatment, patients are followed for short term and long term follow up and survival.

PROJECTED ACCRUAL: Approximately 100 patients will be accrued to this study.

Inclusion and exclusion criteria

DISEASE CHARACTERISTICS During Dose Escalation:

Histologically or cytologically confirmed diagnosis of 1 of the following:
- Small cell lung cancer (SCLC)
- Other pulmonary tumors of neuroendocrine origin, including neuroendocrine carcinoma or non-SCLC with neuroendocrine features
- Non-pulmonary small cell carcinoma
- Metastatic carcinoid tumor
- Other CD56-positive solid tumor
Diagnoses other than SCLC must have confirmation of tumor CD56 expression before study entry
Relapsed or refractory disease
Must have received at least 1 but no more than 3 prior chemotherapy regimens* and recovered from any acute toxicities
- No prior chemotherapy for carcinoid or neuroendocrine tumors

DISEASE CHARACTERISTICS During MTD Expansion:

Relapsed or refractory Small cell lung cancer (SCLC)
Metastatic Merkel Cell carcinomas
Ovarian carcinomas

At the MTD:

SCLC patients must have received one, but no more than 1 prior chemotherapy regimen Merkel and Ovarian patients must have received at least one prior chemotherapy regimen. Ovarian patients must have received at least one platinum-based regimen.
