Safety and Efficacy of ALD518 for Reducing Oral Mucositis in Head and Neck Cancer Subjects

Phase 2TerminatedNCT01403064

CSL Behring76 enrolled

Overview

The purpose of this study is to evaluate the safety and efficacy of ALD518 in modifying the course of oral mucositis in subjects with head and neck cancer receiving concomitant chemotherapy and radiotherapy

This was a Phase 2, placebo-controlled, double-blind study in subjects newly diagnosed with head and neck cancer (who had not received previous treatment for oral mucositis) and who were receiving concomitant chemotherapy and radiotherapy. Subject eligibility, including tumor staging, was assessed during the screening period, which was to occur within 30 days prior to the initiation of radiation therapy. The radiation therapy treatment period was approximately 7 weeks, depending on the subject's prescribed radiation plan. Prior to the randomized portion of the trial, the first 7 subjects enrolled in the study entered a safety run-in evaluation and received a total of 2 doses of open-label clazakizumab 160 mg IV, 4 weeks apart (Day 0 and Week 4 of radiation); these subjects were not eligible for the randomized portion of the study. Subsequent to completion of the safety run-in, eligible subjects were randomized 1:1:1 to treatment with 2 doses of clazakizumab 160 mg, or clazakizumab 320 mg, or placebo, administered IV 3 weeks apart (Day 0 and Week 3 of radiation therapy). All subjects were to be followed for 4 weeks post last day of radiotherapy treatment for the primary efficacy and safety assessments and then for up to an additional 12 months of long-term follow-up.

Outcomes

Primary Outcomes

Percent of Participants With Adverse Events, Serious Adverse Events and Clinically Significant Laboratory Abnormalities

Time frame: Up to 15 months

Number of Participants With Adverse Events, Serious Adverse Events and Clinically Significant Laboratory Abnormalities

Time frame: Up to 15 months

Percent of Participants With All Grades of Oral Mucositis (OM) at a Radiation Dose of 55 Gy

Gray (Gy) is used as a unit of the radiation quantity absorbed dose that measures the energy deposited by ionizing radiation in a unit mass of matter being irradiated, and is used for measuring the delivered dose of ionizing radiation in applications such as radiotherapy. The 55 Gy ulcerative OM assessment is defined as the first ulcerative OM assessment that occurred on the day of or after the subject received the radiation therapy that first resulted in their cumulative dose of radiation being ≥ 55 Gy

Time frame: Up to 12 weeks

Number of Participants With All Grades of OM at a Radiation Dose of 55 Gy

The 55 Gy ulcerative OM assessment is defined as the first ulcerative OM assessment that occurred on the day of or after the subject received the radiation therapy that first resulted in their cumulative dose of radiation being ≥ 55 Gy

Time frame: Up to 12 weeks

Secondary Outcomes

Percent of Participants With Ulcerative OM at Varying Cumulative Radiation Doses (Gy)

The ulcerative OM assessment at a specific cumulative radiation dose (35 Gy, 45 Gy, 55 Gy or 65 Gy) is defined as the first ulcerative OM assessment that occurred on the day of or after the subject received the radiation therapy that first resulted in the specific cumulative dose of radiation being ≥35 Gy, ≥45 Gy, ≥55 Gy or≥ 65 Gy

Time frame: Up to 12 weeks

Number of Participants With Ulcerative OM at Varying Cumulative Radiation Doses (Gy)
