Assessment

Primary outcomes

Hemostasis rate (ITT analysis; assessment at 4 weeks +/- 1 week from treatment start)

Hemostasis is defined as meeting all of the following:
1. No blood transfusion during the 14 days prior to the efficacy assessment date.
2. No procedures intended to control bleeding for the index lesion between the radiotherapy date and the assessment date (i.e., surgery, endoscopic hemostasis, trans-arterial embolization, or any radiotherapy other than the study treatment).
3. Hemoglobin greater than or equal to 8.0 g/dL at the time of assessment.

Key secondary outcomes

- Hemostasis rate: assessed in ITT at Week 2 (+/-1 week) and Week 8 (+/-2 weeks); in PP at Week 2 (+/-1 week), Week 4 (+/-1 week), and Week 8 (+/-2 weeks)
- Use of antiemetics: record presence/absence, timing, drug name, and dose from pre-registration assessment to 2 weeks after treatment start
- Change in hemoglobin: difference from baseline at Week 2 (+/-1 week), Week 4 (+/-1 week), and Week 8 (+/-2 weeks)
- Change in transfusion volume: for Week 4 assessment, compare total transfusion volume during 20 days before vs 20 days after treatment start; for Week 8 assessment, compare during 40 days before vs 40 days after
- Rebleeding rate: among patients with hemostasis, evaluate presence of rebleeding as per protocol definition
- Time to rebleeding: time from first hemostasis to rebleeding; deaths censored
- Salvage hemostatic treatment: record presence/absence of surgery, endoscopic hemostasis, embolization, or radiotherapy for the target lesion; in applicable cases, assess hemostasis at Week 4 (+/-1 week) from salvage treatment
- Overall survival: from registration to death from any cause
- Symptom score: NRS (0-10) for nausea, appetite loss, fatigue, dyspnea, pain, and stress at baseline, Week 1 (+/-3 days), Week 2 (+/-1 week), Week 4 (+/-1 week), and Week 8 (+/-2 weeks)
- QOL score: EQ-5D-5L at baseline, Week 2 (+/-1 week), Week 4 (+/-1 week), Week 8 (+/-2 weeks), and Month 6 (+/-1 month)
- Adverse events: graded per CTCAE v5.0 (JCOG Japanese translation)

4. Received blood transfusion for tumor bleeding within 4 weeks before registration, or hemoglobin level <8.0 g/dL in a blood test within 4 weeks before registration
5. No prior hemostatic treatment by surgery, endoscopy, or endovascular therapy, or such treatment was performed but was ineffective
6. No confirmed active bleeding from sites other than the target lesion for study treatment
7. No prior radiotherapy to the planned treatment field
