Evaluation of Clinical Efficacy and Safety of Nuvastatic in Cancer Asthenia

All stage I-IV solid tumors patients are planned to receive or already receiving chemotherapy or radiotherapy including palliative chemotherapy and radiotherapy meeting the eligibility criteria will be consented and pre-screened for fatigue using Brief Fatigue Inventory (BFI). Subjects will be administered a BFI questionnaire prior to the commencement of their chemotherapy (preferably 1st chemotherapy cycle) or radiotherapy treatment.

Patients will be assessed again using the BFI questionnaire on day 1 of their next chemotherapy cycle or the following week of radiotherapy. Patients will not be considered for study enrolment if the fatigue severity does not increase by at least one score from the previous assessment during the pre-screening. Those with newly developed fatigue or worsening of their fatigue score (i.e. from moderate to severe, mild to moderate, or mild to severe) will be consented for study enrolment. The subject who signed informed consent, pre-screened and is subsequently eligible for study enrolment/randomization will be enrolled into either Nuvastatic TM or Placebo group

Inclusion criteria

Males or females, ≥ age 18 Patients with solid tumors, Stage I-IV Patients who received, receiving, or plan to receive chemotherapy and/or ≥ 1 week of radiotherapy.

ECOG 0-2 Life expectancy ≥ 6 months Ability and willingness to provide written informed consent and comply with study requirement

Exclusion criteria

• Known allergy to Nuvastatic TM (C5OSEW5050ESA) or any of the excipient used in the preparation of the investigational product 2. Any other known existing condition that contraindicates with the use of investigational product 3. Inability to take or consume the investigational product per protocol-specified route of administration including peptic ulcer disease, chronic gastritis, hypotension, and systolic blood pressure <90mmgHg.
• Inability to understand local language (s) for which BFI, EORTC-QLQ- C30, FACIT-F, visual analogue scale for fatigue questionnaire 5. Any condition (e.g. Psychological, geographical, etc.) that does not permit compliance with the study or follow up procedures 6. Participation in any other clinical study using an investigational medicinal product or device within 28 days prior to baseline visit 7. Treatment with medications or supplements frequently associated with fatigue, such as interferon (within the last four months), beta-blockers, calcium channel blockers, benzodiazepines, sedating antihistamines, antidepressants, antipsychotics, or melatonin. In select instances, patients using these medications may be enrolled if, in the opinion of the investigators, their fatigue is clearly unrelated to the medication.
• Untreated or uncontrolled comorbidities that influence fatigue, including thyroid disorders (TSH> 5 mcIU/mL), anemia (Hemoglobin< 9 g/dL), major depression, active substance abuse, or other conditions as determined by the enrolling physician. Comorbidities that are adequately controlled will not exclude patients.
• Chronic renal failure patients with raised serum potassium levels and abnormal renal function 10. Untreated sleep disorders such as obstructive sleep apnea or restless leg syndrome 11. Decompensated cirrhosis (encephalopathy, gastrointestinal bleeding, ascites, bilirubin > 2) within the last six months 12. Patients planning to travel outside the time zone during the study period 13. Known or suspected significant gastrointestinal motility disorder, obstruction, or structuring disease 14. Severe malnutrition according to WHO criteria. 15. Upon examination, the patients may be deemed to have any of the following conditions:

a. Bipedal edema b. Visible severe wasting c. Weight for height more than 3 standard deviations below the median of international reference population d. Fever related to systemic infection (especially Gram-negative coliforms such as Escherichia coli and Klebsiellapneumoniae), neutropenic sepsis e. Respiratory distress f. Heart failure g. Electrolyte abnormalities (hypophosphataemia, hypokalemia/ hyperkaliemia, hypoglycemia, etc.) h. Marked anorexia i. Profuse diarrhea j. Shock

• The patient is female and is pregnant or fertile and is not practicing adequate methods of contraception, is planning to become pregnant within 1 month of the study, is breastfeeding.

Females who choose to defer breastfeeding until 5 days after the last dose of study drug to allow the elimination of the drug from breast milk will be eligible.
