Here is the design of a clinical trial:

Official Title: Sipjeondaebo-tang for Alleviating Fatigue Measured by Brief Fatigue Inventory and EORTC-QLQ-C30, BR23 Score Change Among Patients With Breast Carcinoma Receiving Chemotherapy

Included conditions:
- Breast Carcinoma

Study Armgroups:
- {'label': 'A group', 'type': 'EXPERIMENTAL', 'description': 'Take Sipjeondaebo-tang on 0\\~2 week, 3\\~5 week of clinical trial period, total of 4 weeks', 'interventionNames': ['Drug: Sipjeondaebo-tang']}
- {'label': 'B group', 'type': 'EXPERIMENTAL', 'description': 'Take Sipjeondaebo-tang on 6\\~8 week, 9\\~11 week of clinical trial period, total of 4 weeks', 'interventionNames': ['Drug: Sipjeondaebo-tang']}

Interventions:
- {'type': 'DRUG', 'name': 'Sipjeondaebo-tang', 'description': 'Herbal medicine which is a compound of 10 herbs.', 'armGroupLabels': ['A group', 'B group'], 'otherNames': ['Deciten granule']}

Primary Outcomes:
- {'measure': 'Brief Fatigue Inventory change', 'timeFrame': '0-5 week'}
- {'measure': 'Brief Fatigue Inventory change', 'timeFrame': '6-11 week'}

Please estimate the sample size based on the assumption: 
Not explicitly stated in the paragraph.
Sample size
        This is a pilot study that examines the feasibility of conducting a large-scaled randomised clinical trial of SJDBT for treating cancer-related fatigue in patients with breast cancer. Considering that a sample size between 24 and 50 has been recommended for a pilot study,17 18 and the sample size of other similar pilot studies, a total of 48 participants will be recruited for the present study.19 20 Thus, 24 participants will be allocated to group A and another 24 to group B.
