Trial Outcomes & Findings for Capecitabine and Temozolomide for Treatment of Recurrent Pituitary Adenomas (NCT NCT03930771)

Last Updated: 2022-08-09

Results Overview

Evaluation of Target lesions: Complete Response (CR): Disappearance of all target lesions. Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum onstudy (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression). Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.

Measure	All Patients All subjects will receive: 1. Capecitabine (oral 5-Fluorouracil) 1500mg/m2 orally per day (divided into two doses with maximum daily dose of 2500mg) on days 1 through 14. 2. Temozolomide (second generation alkylating agent) 150 to 200 mg/m2 orally on days 10 through 14. After completion of 6 cycles, patients achieving a complete or partial tumor response may continue to receive capecitabine temozolomide at the investigator's discretion in the absence of disease progression or unacceptable toxicity. Patients will be monitored for six months after they come off the study (either after completing 6 cycles or in setting of disease progression or unacceptable toxicity). Capecitabine: 1500mg/m2 orally per day (divided into two doses with maximum daily dose of 2500mg) on days 1 through 14. Temozolomide: 150 to 200 mg/m2 orally on days 10 through 14.

SECONDARY outcome

Timeframe: At baseline and every 8 weeks, up to 6 months

Serum prolactin, IGF-1, ACTH, FSH, LH and TSH levels are used to assess changes in pituitary hormone function. These tests will only be repeated if found to be abnormal at baseline.
