Selinexor & Talazoparib in Advanced Refractory Solid Tumors; Advanced/Metastatic Triple Negative Breast Cancer (START)

Ki vehet részt

• All patients must sign an informed consent in accordance with local institutional guidelines
• All patient must not have received prior PARPi including talazoparib
• All patients must not have prior therapy with selinexor
• Age ≥ 18
• Estimated life expectancy of at least 12 weeks
• Has recovered from acute toxicities from prior anti-cancer therapies to grade 2 or lower
• a) Dose escalation phase: Patients with histologically or cytologically confirmed advanced or metastatic solid tumors who have radiological evidence of progressive disease on study entry that is deemed unlikely to benefit from further conventional therapy, or for which no standard therapy is available; Dose expansion phase: Patients with previously treated, advanced or metastatic histologically or cytologically confirmed triple negative breast cancers. Patients must have evidence of progressive disease on study entry after at least one line of anti-cancer therapy. Patients will be stratified into platinum-naïve (not having been treated with platinums-containing chemotherapy in the neoadjuvant, adjuvant or palliative setting), platinum sensitive (defined as having prior objective response or sustained disease control lasting ≥6 months to platinum-containing chemotherapy in the metastatic setting, or relapsed ≥6 months after completing neoadjuvant or adjuvant platinums-containing chemotherapy), and platinum resistant (defined as having progressive disease as the best response or disease control <6 months to platinum-containing chemotherapy in the metastatic setting, or relapsed <6 months after completing neoadjuvant or adjuvant platinums-containing chemotherapy); There is no upper limit on the number of prior treatments provided all inclusion/exclusion criteria are met. Hormone ablation therapy is considered an anti-cancer regimen. Radiation and surgery are not considered anti-cancer regimens
