Background and study aims
This research study aims to explore the potential benefits of using bitter ginger, specifically a natural compound called zerumbone found in bitter ginger plants (Zingiber zerumbet), in cancer patients who have limited treatment options. Bitter ginger has been found to possess several properties, such as anti-inflammatory, antioxidant, and analgesic effects. The study aims to assess whether bitter ginger can improve the quality of life and symptom control in these patients.

Who can participate?
Adult patients over the age of 18 years with advanced solid tumors who have exhausted their treatment options are eligible to participate in this study. The study included both male and female patients with various types of cancers.

What does the study involve?
This pilot study was conducted at a single center and involved a total of 35 patients. Participants were given 400 mg of zerumbone, derived from bitter ginger, twice a day for a duration of eight weeks. The patients visited the clinic for three appointments during the study period, where they underwent clinical examinations, and blood tests, and completed specific questionnaires to assess their quality of life, anxiety, depression, fatigue, and sleep quality. Adverse events were also monitored.

What are the possible benefits and risks of participating?
The study is expected to show promising results in improving the quality of life of patients, particularly in the emotional, social, and activity dimensions. Patients may experience improvements in anxiety, depression, and fatigue. Bitter ginger is generally well-tolerated, with only a few mild side effects expected. However, it is important to note that this is a pilot study with a small number of participants and further research with a larger sample size and a control group is needed to confirm these preliminary findings.

Where is the study run from?
The study was conducted at the clinical oncology outpatient clinics of Anchieta Hospital in São Bernardo do Campo and Mario Covas State Hospital in Santo André, both in São Paulo, Brazil. It was affiliated with the ABC Foundation School of Medicine.

When did the study start and how long is it expected to run for?
June 2018 to February 2023

Who is funding the study?
The study was funded through a partnership between the ABC School of Medicine, the National Institute for Research in the Amazon (Instituto Nacional de Pesquisas da Amazônia - INPA), and the Biozer Laboratory.

Scientific titleBitter ginger (Zingiber zerumbet) for patients with advanced cancer: A pilot clinical study
Study objectivesZerumbone is a natural compound found in bitter ginger plants (Zingiber zerumbet) that shows antiproliferative, antioxidant, anti-inflammatory, and analgesic properties. This study aims to investigate the role of zerumbone in improving the quality of life and symptom control in cancer patients with no treatment options
Ethics approval(s)

Approved 20/08/2018, ABC Foundation School of Medicine (Faculdade de Medicina da Fundação ABC; FMABC) (Avenida Príncipe de Gales 821, Santo André, 09060-650, Brazil; +55114993-5453; cep@fmabc.br), ref: 93459418.1.0000.0082

Health condition(s) or problem(s) studiedPatients with advanced solid tumors without any more specific anti-neoplastic treatment options
InterventionIn this pilot study, patients were recruited from clinical oncology outpatient clinics in São Bernardo do Campo and Santo André, São Paulo, Brazil. Zingiber zerumbet (ZZ) rhizomes were collected from Manaus, Amazonas, Brazil, and processed to obtain crude and hydroalcoholic extracts. The extracts were analyzed using thin-layer chromatography (TLC) and high-performance liquid chromatography (HPLC) to identify their components. The Zingiber zerumbet rhizome extract was encapsulated in 400 mg gelatin capsules and given to participants to be administered twice a day for eight weeks. Adherence to the treatment was monitored by evaluating the returning medication packages. The protocol involved three visits: the first visit (T = 0) before initiating the treatment, followed by two other visits every four weeks until week eight of treatment. At each visit, the patients underwent anamnesis, clinical examination, blood collection, and specific questionnaire assessments.
