About

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

Full description

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.

Inclusion criteria

• History of newly diagnosed histologically confirmed squamous cell carcinoma (American Joint Committee on Cancer [AJCC] Stage II, III, IVA, or IVB) involving either the oral cavity, oropharynx, nasopharynx, hypopharynx, or larynx, post surgical resection (R0, R1)
• Scheduled to receive adjuvant concurrent chemoradiation treatment within 12 weeks of surgery
• High-risk subject defined by presence of at least one of the following: R1 resection margins; T3 or T4 tumor stage; 3 or more positive lymph node metastases; <3 lymph node metastases with extracapsular extension of the disease
• Radiation treatment field to receive planned dose of at least 50Gy to areas of the oral cavity/oropharynx mucosa that can be visualized

Exclusion criteria

• Tumors of the lips, paranasal sinuses, salivary glands, or of unknown primary tumors
• Metastatic disease (M1) / Stage IV C
• Presence or history of any other primary malignancy
• History of pancreatitis
• Prior radiotherapy to the site of disease
• Prior chemotherapy
• Other investigational procedures
• Thirty days or less since receiving an investigational product or device in another clinical trial. Current enrollment in another clinical trial is not permitted unless the sole purpose of the trial is for long-term follow-up/survival data

Masking: Double Blind

---

5 participants in 2 patient groups, including a placebo group

Placebo

Placebo Comparator group

Description:

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.

Treatment:

Drug: Cisplatin

Drug: Placebo

Radiation: Radiotherapy

Palifermin

Experimental group

Description:

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.

Treatment:

Drug: palifermin

Drug: Cisplatin

Radiation: Radiotherapy
