We have now completed the inclusion of 1,440 women in the Karisma-2 double-blinded clinical trial at the breast centre at Södersjukhuset in Stockholm and at Unilabs in Lund.
Karisma-2 is adose optimisation study using tamoxifen for preventive use.Women were randomised to five arms of tamoxifen or placebo and are treated for six months.
Tamoxifen is used by breast cancer patients to lower the risk of a breast cancer recurrence. It has been shown that perfectly healthy women lower their risk of breast cancer by 50% if they use tamoxifen. However, tamoxifen is not used for prevention due severe side effects.
Preliminary results are expected in late autumn 2019.
