To evaluate whether palifermin (rHuKGF) administered as a single dose is non-inferior to 3 consecutive doses of palifermin in reducing the incidence of severe oral mucositis (World Health Organization \[WHO\] grade 3 and 4).

Administered as one daily intravenous bolus.

Cyclophosphamide is administered at a total dose of 100 mg/kg given in 1 dose on Day -2
Number of Participants With Severe Oral Mucositis (WHO Grade 3 and 4)
Participants underwent evaluations of oral mucosal (OM) surfaces (mucositis assessments) daily during hospitalization and daily thereafter until severe OM returned to grade ≤ 2. A trained evaluator documented the findings using the World Health Organization (WHO) oral toxicity scale according to the following: Grade 0 = None; Grade 1 = Soreness, erythema; Grade 2 = Erythema, ulcers, ability to eat solids; Grade 3 = Ulcers, requires liquid diet; Grade 4 = Alimentation not possible.
Time frame: Up to Day 28
Duration of Severe Oral Mucositis (WHO Grade 3 and 4)
The duration of severe oral mucositis (OM) was calculated as the number of days from the onset of severe OM (first time a WHO grade 3 or 4 was observed) to the day when severe OM was resolved (first time WHO grade 2 or less was observed after last WHO grade 3 or 4). Durations of 0 days were assigned to those participants who did not experience any WHO grade 3 or 4 during the study.
Time frame: Up to Day 28
Area Under the Curve (AUC) of Mouth and Throat Soreness Score
The Oral Mucositis Daily Questionnaire (OMDQ) is a self-reported tool that evaluates overall health, mouth and throat soreness (MTS) and activity limitations due to MTS. The OMDQ was completed once daily beginning with the first day of study drug administration through Day 28. The area under the curve of mouth and throat soreness score was assessed from the question "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). A higher value in MTS AUC indicates worse self-assessed MTS.
Time frame: From the first day of study drug administration through Day 28
Number of Participants With Parenteral or Transdermal Opioid Analgesic Use
Includes nonprophylactic intravenous opioid analgesics (fentanyl, morphine, morphine sulphate, hydromorphone, meperidine) and transdermal opioid analgesics (fentanyl patch) for the indication of oral mucositis and dysphagia.

Etoposide may be administered (optional) as a single intravenous infusion over 4 hours on the day after the last fTBI fraction.
Administered as one daily intravenous bolus.
Time frame: Up to Day 28
Number of Participants With WHO Grades 2, 3 or 4 Oral Mucositis
Participants underwent evaluations of oral mucosal (OM) surfaces (mucositis assessments) daily during hospitalization and daily thereafter until OM returned to grade ≤ 2. A trained evaluator documented the findings using the World Health Organization (WHO) oral toxicity scale according to the following: Grade 0 = None; Grade 1 = Soreness, erythema; Grade 2 = Erythema, ulcers, ability to eat solids; Grade 3 = Ulcers, requires liquid diet; Grade 4 = Alimentation not possible.
Time frame: Up to Day 28
Duration of WHO Grade 2, 3 or 4 Oral Mucositis
The duration of grade 2, 3 or 4 oral mucositis (OM) was calculated as the number of days from the onset of grade 2, 3 or 4 OM (first time a WHO grade 2, 3 or 4 was observed) to the day when WHO grade 2 - 4 OM was resolved (first time WHO grade less than 2 was observed after last WHO grade 2, 3 or 4). Durations of 0 days were assigned to those participants who did not experience any WHO grade 2, 3 or 4 during the study. OM was evaluated using the World Health Organization (WHO) oral toxicity scale according to the following: Grade 0 = None; Grade 1 = Soreness, erythema; Grade 2 = Erythema, ulcers, ability to eat solids; Grade 3 = Ulcers, requires liquid diet; Grade 4 = Alimentation not possible.
Time frame: Up to Day 28
Number of Participants With WHO Grade 4 Oral Mucositis
Participants underwent evaluations of oral mucosal (OM) surfaces (mucositis assessments) daily during hospitalization and daily thereafter until OM returned to grade ≤ 2. A trained evaluator documented the findings using the World Health Organization (WHO) oral toxicity scale according to the following: Grade 0 = None; Grade 1 = Soreness, erythema; Grade 2 = Erythema, ulcers, ability to eat solids; Grade 3 = Ulcers, requires liquid diet; Grade 4 = Alimentation not possible.
