Study Description

Brief Summary:

This study aims to evaluate the efficacy and safety of preoperative Durvalumab in patients with early small (cT1N0) triple negative breast cancer tumors. This study will recruit patients with early HR-negative breast cancer all invasive types (ER < 1%, PR < 1%, HER2 negative) and TILs >=5%, eligible for a short-term treatment with Durvalumab. A total of 200 patients are planned to be enrolled in the study and which will receive 2 administrations of durvalumab 10mg/kg.

After study treatment, patients:

• In whom surgery is the first standard treatment strategy (i.e. after study treatment) no biopsy is required at the end-of-treatment visit.
• In whom neo adjuvant therapy is the first standard treatment strategy (i.e. after study treatment) a breast ultrasound guided biopsy is mandatory at the EoT visit. If the biopsy-proven residual disease is demonstrated, patients will have the option to receive standard neoadjuvant therapy at the discretion of the treating investigator. Those with a complete response may proceed directly to surgery.

Arms and Interventions

Arm	Intervention/treatment
Experimental: Durvalumab; All patients enrolled in the study will receive 2 administrations of durvalumab 10mg/kg monotherapy before any standard treatment.

Outcome Measures

Primary Outcome Measures :

1. pCR rate after 2 administrations of durvalumab [ Time Frame: Assessed at Day 29 (for patients performing surgery) or at Day 22 (for patients starting neoadjuvant systemic treatment) ]
   Defined as the absence of invasive disease in the breast and negative axillary nodes (ypT0/yTis ypN0)

Secondary Outcome Measures :

1. Evaluation of objective response rate (ORR) [ Time Frame: After 2 administrations of durvalumab ]
   To assess if 2 administrations of durvalumab are associated with decreased tumor size as determined by the RECIST1.1
2. Severity of adverse events [ Time Frame: From baseline to 30 days after last administration of durvalumab ]
   as assessed by CTCAE v5.0
3. Incidence of adverse events [ Time Frame: From baseline to 30 days after last administration of durvalumab ]
   as assessed by CTCAE v5.0
4. Nature of adverse events [ Time Frame: From baseline to 30 days after last administration of durvalumab ]
   as assessed by CTCAE v5.0

Eligibility Criteria

• Ages Eligible for Study: 18 Years and older (Adult, Older Adult)
• Sexes Eligible for Study: Female
• Accepts Healthy Volunteers: No

Criteria

Inclusion Criteria:

• Patient should understand, sign, and date the written informed consent form (including the consent to collect tissue, blood and stool samples, as specified by the protocol) prior to any protocol-specific procedures performed. Patient should be able and willing to comply with study visits and procedures as per protocol.
• Female patients aged 18 years or older
• Histologically confirmed untreated invasive carcinoma of the breast (ER < 1%, PR < 1%, HER2 negative) as locally determined
• Tumor infiltrating lymphocites (TILs) ≥ 5% in breast tumor biopsy as locally determined
• Breast cancer clinical TNM stage I (cT1N0 as measured by radiological imaging). Bilateral, multicentric and multifocal tumors are allowed, assuming tumor evaluations and pre- and post-treatment biopsies are performed in the same target lesion. Only the largest tumor will be measured to determine the study eligibility.
• No evidence of metastatic disease or confirmed lymph node involvement
• Eastern Cooperative Oncology Group (ECOG) performance status 0/1
• Patients of child-bearing potential are eligible, provided they have a negative serum β-hCG pregnancy test within 2 weeks or urine pregnancy test within 48 hours prior to the first dose of study treatment, and agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods with a failure rate of < 1% per year during the treatment period and for 3 months after the last dose of durvalumab Note: A woman is considered of childbearing potential following menarche and until becoming post-menopausal (≥ 12 months of non-therapy-induced amenorrhea) unless permanently sterile. Permanent sterilization methods include hysterectomy, bilateral oophorectomy and bilateral salpingectomy.
• Sexually active women of childbearing potential must agree to use a highly effective method of contraception supplemented by a barrier method, or to abstain from sexual activity during the study and for at least 3 months after the last study treatment administration. Female subjects should also refrain from breastfeeding throughout this period.

Note: A highly effective birth control method is a one, which can achieve a failure rate of less than 1% per year when used consistently and correctly. Such methods include: combined (estrogen and progestogen containing) hormonal contraception; progestogen-only hormonal contraception associated with inhibition of ovulation; intrauterine device (IUD); intrauterine hormone-releasing system (IUS); bilateral tubal occlusion; vasectomized partner (on the understanding that this is the only one partner during the whole study duration), and sexual abstinence during the entire period of risk associated with study treatment. To prevent the risk of interaction between the study drug and hormonal contraceptives, hormonal contraceptives should be supplemented with a barrier method (preferably male condom). Following methods are considered as unacceptable methods (non-exhaustive list): periodic abstinence (calendar, symptothermal, post-ovulation methods) and withdrawal (coitus interruptus).
