Primary
| Measure | Time frame |
|---|---|
| Biodistribution and Pharmacokinetics Biodistribution (Body gammagraphy. Distribution of the radiolabeled peptide in tumor and main source organs). Measuring time: 10 min, 1h, 2h, 4h, 8h, 12h, 16h, 24h, 36h and 48h after the first administration. Pharmacokinetic studies in serum, whole blood and urine (measurement of activity, and quantification of CIGB-300 serum by ELISA and HPLC). Measuring time: Immediately, 5 min, 15 min, 30 min, 1h, 2h, 4h, 8h, 12h, 16h, 24h, 36h and 48h after the first dose. The urine will be collected at intervals during this sampling period to determine the excreted magnitude and renal clearance. Safety variables: Presence of severe adverse events (Yes, No). Measuring time: until 24 hours after each administration. Presence of clinical Adverse Events (AE). Measuring time: until 24 hours after each administration. Then, patients will be followed during and at 3, 6, 9, and 12 months after chemo-radiotherapy. - Appearance of AE (Yes, No) - Type of AE (name of the AE) - Duration of AE (time from appearance to end of the event) - Intensity of AE (mild, moderate, severe) - Relation of causality (remote, possible, probable, very probable) - Result of AE (recuperate, improvement, persist or sequels) - Attitude concerning the studied treatment (without changes, dose modification, temporal or definitive treatment discontinuation). Vital signs (body temperature in Celsius degrees, heart rate in beats per minute, blood pressure in mmHg and respiratory rate in breaths per minute). Measuring time: before each dose, at 30min, 1h, 1h, 2h, 3h, 4h, 12h and 24h after each dose. Laboratory tests (complete blood count, glucemy, creatinine, transaminases). Measuring time: At baseline, and 21 days after treatment. Later weekly during chemo-radiotherapy and each three months during a one-year follow-up. Histamine plasmatic levels ( ELISA techniques). Measuring time: At baseline, 15min and 24h after the first dose; and at any other moment if a possible histamine rele | — |
Secondary
| Measure | Time frame |
|---|---|
| Therapeutic response: Clinical colposcopic evaluation (Size of the tumoral lesion in diameters and area of the tumor surface captured by digital picture and measured using MADIP software). Measuring time: At baseline and 21 days after treatment. Later each three months during a one-year follow-up after chemo-radiotherapy. Imagenological evaluation (Tumor size using abdominal and transvaginal ultrasonography, CT scans, MRI, according to the evaluation criteria for solid tumors-RECIST). Measuring time: At baseline and 21 days after treatment. Later each three months during a one-year follow-up after chemo-radiotherapy. | — |
