Outcome Measures

Primary Outcomes (1)

  • duration in months from beginning of treatment till development of CRPC

    time till development of CRPC \[Castrate resistant prostate cancer\], is defined by disease progression despite androgen depletion therapy (ADT) and may present as either a continuous rise in serum prostate-specific antigen (PSA) levels, the progression of pre-existing disease, and/or the appearance of new metastases.

    2 years

Secondary Outcomes (2)

  • CRPC free survival

    4 years

  • Overall patients' survival

    4 years

Study Arms (2)

Investigational arm

ACTIVE COMPARATOR

Metformin will be added to standard of care

Drug: Metformin

Control arm

NO INTERVENTION

Patients will treated according to Standard of care only

Interventions

Metformin will be added as a daily treatment to the standard treatment in both neoadjuvant and adjuvant settings of locally advanced cases and lifelong to metastatic cases. The starting daily dose of metformin is 850mg Once daily, to be increased to 850 mg if tolerated

Also known as: Cidophage
