A Study of Palifermin for the Reduction of Oral Mucositis in Patients With Locally Advanced Head and Neck Cancer Receiving Postoperative Radiotherapy and Concurrent Chemotherapy

29 mai 2017 mis à jour par: Swedish Orphan Biovitrum

A Phase 1/2 Study to Evaluate Safety, Pharmacokinetics, Pharmacodynamics and Preliminary Efficacy of Weekly Doses of Palifermin (rHuKGF) for the Reduction of Oral Mucositis in Subjects With Locally Advanced Head and Neck Cancer (HNC) Receiving Postoperative Radiotherapy With Concurrent Chemotherapy

Oral Mucositis associated with adjuvant radiation and concurrent chemotherapy in postoperative Head and Neck setting

Aperçu de l'étude

Description détaillée

This study consisted of 2 phases. The acute oral mucositis (OM) evaluation phase includes the time from randomization to the time of severe OM (WHO Grade 3 or 4) resolution (up to Week 12 or up to Week 15 for participants whose severe OM is not resolved at Week 12). In the acute OM evaluation phase, participants were randomized to receive either a single IV bolus dose of palifermin or placebo at 120 μg/kg, 3 days before the start of radiotherapy, plus 7 once-weekly palifermin or placebo doses at the same dose level during a 7-week radio/chemotherapy course. In the long-term follow up phase, participants are followed until death, withdrawal of consent, or loss to follow-up. The long-term follow up phase is still ongoing.

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Comparateur placebo: Placebo
Three days before the start of radiotherapy (Day -3), participants received a single intravenous (IV) bolus injection of matching placebo. During radiotherapy (beginning on Day 1), participants received a weekly single IV bolus injection of matching placebo after the last radiation fraction of that week (usually on Fridays) until grade ≥3 oral mucositis occurred, or for a maximum 8 doses (completion of radiotherapy). Participants also received cisplatin 100 mg/m^2 on days 1, 22 and 43.
Administered by intravenous (IV) bolus injection
Once daily irradiation of 20 centigray (cGy)/day x 33 fractions for a total target dose of 6600 cGy (conventional radiation therapy using standard fractionation [one fraction per day])
100 mg/m^2 intravenously (IV) on days 1, 22 and 43.
Expérimental: Palifermin
Three days before the start of radiotherapy (Day -3), participants received a single intravenous (IV) bolus injection of palifermin at 120 μg/kg. During radiotherapy (beginning on Day 1), participants received a weekly single IV bolus injection of palifermin at 120 μg/kg after the last radiation fraction of that week (usually on Fridays) until grade ≥3 oral mucositis occurred, or for a maximum 8 doses (completion of radiotherapy). Participants also received cisplatin 100 mg/m^2 on days 1, 22 and 43.

Mesure des résultats
Description de la mesure
Délai
Number of Participants With Adverse Events (AEs)
Délai: Up to Week 12 (or Week 15 for participants with severe OM was not resolved by Week 12)
An adverse event is an undesirable medical occurrence (sign, symptom, or diagnosis) or worsening of a pre-existing medical condition occurring after start of study drug up to the end of acute oral mucositis (OM) evaluation phase, whether or not considered to be study drug related. If severe OM was not resolved by Week 12, AEs were documented until resolution of severe OM or Week 15, whichever occurred first. A serious AE is any event that is fatal, life threatening, requires or prolongs hospitalization, is a persistent or significant disability/incapacity or is a congenital anomaly/birth defect. The intensity of AEs was graded according to the Common Terminology Criteria for Adverse Events (CTCAE) v3 based on the following: Grade 1 = Mild AE, Grade 2 = Moderate AE, Grade 3 = Severe AE, Grade 4 = Life-threatening or disabling AE, Grade 5 = Death related to AE. A Protocol-specific Limiting Toxicity (PSLT) is any non-hematologic Grade 3 or 4 AE considered related to study drug.
Up to Week 12 (or Week 15 for participants with severe OM was not resolved by Week 12)
Ratio of Ki67-positive Cells Before and After Palifermin Treatment
Délai: Day -3 predose and 24 or 48 hours post-dose
The effect of palifermin on cell proliferation was to be assayed by staining for the cell cycle proliferation marker Ki67 in buccal mucosal biopsy samples taken prior to the first dose and either 24 or 48 hours after the first dose. Due to the small sample size, this analysis was not performed.
Day -3 predose and 24 or 48 hours post-dose
Pharmacokinetics of Palifermin
Délai: Day -3, predose and at 2, 5, 15, 30, 60, and 90 minutes and 2, 4, 6, 8, 10, 12, 24 and 48 hours after the first dose
Due to the small sample size this analysis was not performed.
Day -3, predose and at 2, 5, 15, 30, 60, and 90 minutes and 2, 4, 6, 8, 10, 12, 24 and 48 hours after the first dose

Patient-Reported Mouth and Throat Soreness Score
Délai: Assessed daily up to Week 12 (or Week 15 if severe oral mucositis not resolved ≤ adapted RTOG/EORTC Grade 2 by Week 12).

The average patient-reported mouth and throat soreness (MTS) score as reported on question 3 of the Oral Mucositis Questionnaire for Head and Neck Cancer [OMQ-HN]): "How much mouth and throat soreness did you experience in the past 24 hours?" Participants answered on a scale from 0 (no soreness) to 4 (extreme soreness).

Due to the small sample size this analysis was not performed.

Assessed daily up to Week 12 (or Week 15 if severe oral mucositis not resolved ≤ adapted RTOG/EORTC Grade 2 by Week 12).
Number of Participants With Disease Progression by Week 12
Délai: Up to Week 12
Disease progression was determined by clinical examination and histopathologic examination by the Investigator.
Up to Week 12
