Eredeti leírás

About 10-20% of all individuals with breast cancer have a so-called triple-negative tumor (TNBC). This type of breast cancer has a particularly unfavorable course and a higher mortality rate compared to other forms of breast cancer. Research studies show that it is important for individuals with TNBC to achieve a so-called pathologic complete response (pCR) to treatment. In the phase II study SAKK 66/22, it is being investigated whether the administration of the drug INT230-6 before surgery for breast cancer can increase the rate of pCR in the tumor and affected lymph nodes. The tolerability of INT230-6 as well as other factors such as response to treatment and the possibility of breast-conserving surgery are also being examined.A teljes eredeti leírásKevesebb

If multifocal or multicentric disease TNBC needs to be confirmed for each focus; Measurable disease in the breast with at least one lesion with a diameter ≥ 1.5cm that is evaluable per RECIST v1.1, visible in ultrasound and injectable; Male or female subject Age ≥ 18 years; ECOG performance status 0-1; Adequate bone marrow function (administration of G-CSF, EPO and/or blood transfusion within 14 days before registration is not allowed):; neutrophil count ≥ 1.5 x 109/L; platelet count ≥ 100 x 109/L; hemoglobin ≥ 90 g/L; Adequate hepatic function:; total bilirubin ≤ 1.5 x ULN, or direct bilirubin ≤ ULN for subjects with total bilirubin levels > 1.5 x ULN; AST and ALT ≤ 2.5 x ULN,; Albumin 30 ≥ g/L; Lactate Dehydrogenase (LDH) <2.5 ULN; Adequate renal function: estimated glomerular filtration rate (eGFR) ≥ 50 ml/min/1.73 m2 (according to CKD-EPI formula); Adequate cardiac function: Left ventricular Ejection Fraction (LVEF) ≥ 50% as determined by echocardiography (ECHO); Adequate coagulation function:; INR ≤ 1.5 x ULN unless the patient is receiving anticoagulant therapy; aPTT ≤ 1.5 x ULN unless the patient is receiving anticoagulant therapy; If the patient is receiving anticoagulant therapy, the treating physician must determine that the anticoagulation can be stopped at least 24 hours prior to injection; Women of childbearing potential must use highly effective contraception, are not pregnant or lactating and agree not to become pregnant during trial treatment and until 7 months after the last dose of INT230-6 or 6 months after standard of care treatment. A negative pregnancy test before inclusion into the trial is required for all women of childbearing potential. (www.swissmedicinfo.ch); Men agree not to donate sperm or to father a child by using effective contraception during trial treatment and until 6 months after the last dose of INT230-6 or standard of care treatment (www.swissmedicinfo.ch).

Kizáró feltételek: Unfavorable relation between tumor size and breast size as determined by judgement of the treating physician, surgeon and/or investigator, where tumor shrinkage during neoadjuvant immunochemotherapy is required for breast conserving surgery to be considered; Prior chemotherapy, targeted therapy, radiation therapy or anti-PD-L1 agent for previous breast cancer or Ductal Carcinoma in Situ (DCIS) on the same side; Concurrent bilateral breast cancer; Concomitant treatment with any other experimental drug for recent breast cancer diagnosis in another clinical trial; Receipt of live attenuated vaccine (including yellow fever vaccine) within 30 days prior to registration; Diagnosis of immunodeficiency, concomitant or prior use of immunosuppressive medication within 7 days before registration, with the exceptions of local (intranasal, topical and inhaled) corticosteroids, or systemic corticosteroids which must not exceed 10 mg/day of prednisone or a dose equivalent corticosteroid, and the premedication for chemotherapy; Any concomitant drugs contraindicated for use with the trial drug according to the Investigator Brochure (IB) and the immuno-chemotherapy treatment according to the approved product information; Inflammatory Breast Cancer cT4d; Known history of human immunodeficiency virus (HIV) or active chronic hepatitis C or hepatitis B virus infection or any uncontrolled active systemic infection requiring intravenous (iv) antimicrobial treatment; Active autoimmune disease that required systemic treatment in past 2 years (e.g., with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroid hormone replacement, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment; History of (non-infectious) pneumonitis that required steroids or current pneumonitis; Known history of tuberculosis; Known history of allogeneic organ or stem cell transplant; Known hypersensitivity to trial drug or to any component of the trial drug or immuno-chemotherapy treatment; Incapacitated adults and any other serious underlying medical, psychiatric, psychological, familial or geographical condition, which in the judgment of the investigator may interfere with the planned staging, treatment and follow-up, affect patient compliance or place the patient at high risk from treatment-related complications; Severe or uncontrolled cardiovascular disease (congestive heart failure NYHA II or IV; unstable angina pectoris, history of myocardial infarction and acute coronary syndrome requiring stenting/bypass surgery within the last six months, serious arrhythmias requiring medication (with exception of atrial fibrillation or paroxysmal supraventricular tachycardia), significant QT-prolongation, uncontrolled hypertension; Concomitant anticoagulation with warfarin or equivalent vitamin K antagonists (e.g. phenprocoumon), factor Xa inhibitors (e.g. rivaroxaban, apixaban), direct thrombin inhibitors (e.g. dabigatran) or platelet inhibitors/antiplatelet agents that cannot be stopped 24 hours before the administration of INT230-6. Aspirin (up to 300 mg/day) is allowed; History of invasive malignancy ≤3 years prior to signing informed consent (except treated basal cell or squamous cell skin cancer or in situ cervical cancer); Unfavorable tumor location that can potentially result in an unfavorable cosmetic outcome (e.g. high upper inner quadrant) and/or close skin contact by judgment of the treating physician, surgeon and/or investigator; The following histological subtypes of TNBC are excluded: Classic adenoid cystic carcinoma, secretory carcinoma, low-grade adenosquamous carcinoma, tall cell carcinoma with reversed polarity, high-grade metaplastic.
