Health condition and Intervention

Section to complete information about the primary medical condition(s) or problem(s) studied and, a characteristics of the intervention(s).

Health condition(s) or Problem(s) studied:

Cervical epidermoid carcinoma, stage IB2-II.

Intervention(s):

Study group (CIGB-300, 35 mg): Doses of 35 mg resuspended in 1 ml of water for injection, applied by intratumor route in 3 cycles of daily applications for 3 days in the weeks 1, 3 and 5, respectively. In each cycle, the product will be administered as unique treatment (simple agent), and after the last cycle (week 5) the conventional chemo-radiotherapy (CRT) treatment will begin. Conventional chemo-radiotherapy consists in cisplatin 40 mg/m2, once per week, during 6 weeks, concomitant to 5040 cGy of external beam radiotherapy given in 28 fractions. This will be followed by 2600 cGy of intracavitary radiotherapy given in 4 high dose fractions (650 cGy/day) over 2 weeks. Study group (CIGB-300, 70 mg): Doses of 70 mg resuspended in 1 ml of water for injection, applied by intratumor route in 3 cycles of daily applications for 3 days in the weeks 1, 3 and 5, respectively. In each cycle, the product will be administered as unique treatment (simple agent), and after the last cycle (week 5) the conventional CRT treatment will begin. Conventional chemo-radiotherapy consists in cisplatin 40 mg/m2, once per week, during 6 weeks, concomitant to 5040 cGy of external beam radiotherapy given in 28 fractions. This will be followed by 2600 cGy of intracavitary radiotherapy given in 4 high dose fractions (650 cGy/day) over 2 weeks. These two dose levels were well-tolerable in the previous study CERVIFARM-300, where 70 mg was the maximum tolerable dose.

Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

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 y 24h 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 y 24h after the first dose. The urine will be collected at intervals during this sampling period to determine the excreted magnitude and renal clearance.

Key secondary outcomes:

Safety variables: Presence of severe adverse events (Yes, No). Measuring time: at each administration. Presence of clinical Adverse Events (AE). Measuring time: at each administration. - 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 and 12h after each dose. Laboratory tests hemoglobin, white blood cells counts, globular sedimentation rate, coagulation parameters, glucemy, transaminases, bilirubin, alkaline phosphatase, urea, creatinine). Measuring time: Before and 24 hours after each CIGB-300 cycle. Afterwards weekly during chemo-radiotherapy and each three months during a one-year follow-up. Histamine plasmatic levels (ELISA techniques). Measuring time: At baseline, 5min, 15min,30min and 60min after the first dose. 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: Before and 24 hours after each cycle and whenever it is required by safety requirements. Biweekly during CRT and quarterly until complete 1 year after CRT. Imagenological evaluation (Tumor size using abdominal and transvaginal ultrasonography, CT scans, MRI, according to the evaluation criteria for solid tumors-RECIST). Measuring time: Before CIGB-300 treatment. After the last CIGB-300 cycle (week 5). After the whole treatment quarterly until complete 1 year. Biological response: Expression of B23/nucleophosmin in tumors (Immunohistochemistry análisis) in paraffin-embedded tumor biopsies will be carried out. Measuring time: before CIGB-300 treatment and 24 hours after the third (last) cycle. Anti-B23 (nucleophosmin) antibodies (ELISA techniques). Measuring time: At baseline, 24h after 3rd cycle and 3 months after chemo-radiotherapy.
