Critères
Tous
1. Male or female patients (who are ≥18 years of age at the time of signing the
informed consent) who have a pathologically documented breast cancer that is:
- Advanced/unresectable (patients who can be treated with curative intent are not
eligible) or metastatic.
- HER2-negative (IHC 0, 1+ or IHC 2+/ISH-) based on local assessment according to
ASCO/CAP guidelines 1.
- Documented as hormone receptor-negative (both oestrogen receptors and
progesterone receptors are negative [oestrogen receptors and progesterone
receptors < 10%]) as per GEFPICS guidelines in the metastatic setting 2.
2. Patients need to provide an adequate tissue sample: provided from either a new
biopsy of a metastatic site or the most recent archival biopsy taken at the time of
diagnosis of metastatic disease, if performed within 1 month of the ICF signature.
Additionally, an archival sample of the primary tumor may be submitted (if
available) in addition to any recent archival tissue provided.
3. Patients who have early relapsed triple negative breast cancer i.e.:
- Patients who have received neo/adjuvant chemotherapy in the localized stage.
- Radiological and anatomopathological evidence of disease recurrence or
metastasis while on (neo)adjuvant treatment or within 12 months from the end of
all treatments with curative intent.
4. Patients with germinal pathological BRCA1/2 mutations are eligible to the study if
they have received prior treatment with PARP inhibitor.
5. ECOG PS of 0 to 2.
6. LVEF ≥ 50% within 28 days before enrolment.
7. Adequate organ and bone marrow function within 14 days prior to treatment
assignment.
8. At least one lesion, not previously irradiated (and different from the biopsy site),
that qualifies as a RECIST 1.1 target lesion at baseline.
9. An adequate treatment washout period before randomization/enrolment.
10. Patients with leptomeningeal or brain metastases can be included in the trial if
symptoms are controlled with corticosteroids until 10 mg/day of prednisone or
equivalent. Patients with brain metastases must receive radiotherapy if indicated,
before study entry. Anticonvulsant therapy must be stable for at least 14 days prior
to C1D1.
Reproduction
11. Evidence of post-menopausal status or negative serum pregnancy test for females of
child-bearing potential who are sexually active with a non-sterilized male partner.
For women of child-bearing potential, a negative result for a pregnancy test (A
negative serum pregnancy test at screening visit and a negative serum or urine
pregnancy test within 72 hours prior to first study treatment administration).
Women will be considered post-menopausal if they have been amenorrhoeic for at least
12 months without an alternative medical cause. The following age-specific
requirements apply:
- Women < 50 years of age would be considered post-menopausal if they have been
amenorrhoeic for 12 months or more following cessation of exogenous hormonal
treatments and if they have luteinizing hormone and follicle-stimulating
hormone levels in the post-menopausal range for the institution.
- Women ≥ 50 years of age would be considered post-menopausal if they have been
amenorrhoeic for 12 months or more following cessation of all exogenous
hormonal treatments, had radiation-induced menopause with last menses> 1 year
ago, had chemotherapy-induced menopause with last menses > 1 year ago).
12. Women who are surgically sterile (i.e., bilateral salpingectomy, bilateral
oophorectomy, or complete hysterectomy) are eligible.
13. Female patients of child-bearing potential who are sexually active with a
non-sterilized male partner must use at least one highly effective method of
contraception from the time of screening and must agree to continue using such
precautions for 7 months after the last dose of study treatment. Not all methods of
contraception are highly effective. Female patients must refrain from egg cell
donation and breastfeeding while on study and for 7 months after the last dose of
study treatment. Not engaging in sexual activity for the duration of the study and
drug washout period is an acceptable practice; however, periodic, or occasional
abstinence, the rhythm method, and the withdrawal method are not acceptable methods
of contraception.
14. Non-sterilized male patients who are sexually active with a female partner of
child-bearing potential must use a condom with spermicide from screening to 4 months
after the final dose of study treatment. Not engaging in sexual activity for the
duration of the study and drug washout period is an acceptable practice; however,
periodic, or occasional abstinence, the rhythm method, and the withdrawal method are
not acceptable methods of contraception. It is strongly recommended for the female
partners of a male patient to also use at least one highly effective method of
contraception throughout this period. In addition, male patients should refrain from
fathering a child or donating sperm during the study and for 4 months after the last
dose of study treatment. Preservation of sperm should be considered prior to
enrollment in this study.
15. Female patients must not donate, or retrieve for their own use, ova from the time of
screening and throughout the study treatment period, and for at least 7 months after
the final study treatment administration. Preservation of ova should be considered
prior to enrollment in this study Informed Consent
16. Patient must understand, sign and date the written informed consent form (ICF) prior
to any protocol-specific procedures performed. Patient should be able and willing to
comply with study visits and procedure as per protocol.
17. Patient must be affiliated to a social security system or beneficiary of the same.
Exclusion Criteria:
1. Evidence of untreated spinal cord compression or with leptomeningeal or brain
metastases, requiring more than 10 mg/day of prednisone or equivalent.
Note: Untreated spinal cord compression: patients can enter the study after adequate
treatment of spinal cord compression.
2. Uncontrolled intercurrent illness, including but not limited to, ongoing or active
infection, uncontrolled or significant cardiovascular disease, severe pulmonary
function compromise, serious chronic gastrointestinal conditions associated with
diarrhea, or psychiatric illness/social situations that would limit compliance with
study requirements, substantially increase risk of incurring AEs or compromise the
ability of the patient to give written informed consent.
3. Has a clinically significant corneal disease.
4. Has a history of non-infectious ILD/pneumonitis including radiation pneumonitis that
required steroids, has current ILD/pneumonitis, or has suspected ILD/pneumonitis
that cannot be ruled out by imaging at screening.
5. Uncontrolled or significant lung disease or prior pneumonectomy.
6. Active connective tissue or inflammatory disorders requiring treatment, or active or
prior documented autoimmune disease within the past 5 years. Of note, patients with
vitiligo, Grave's disease or psoriasis not requiring systemic treatment (within the
past 2 years) are not excluded. Patients with type 1 diabetes or hypothyroidism
stable under treatment or not requiring systemic treatment are eligible.
7. Active primary immunodeficiency.
8. Has active or uncontrolled hepatitis B or C virus infection.

which are not attributable to HBV infection iii. Start or maintain antiviral
treatment if clinically indicated as per the investigator
9. Patients with known controlled HIV infection and undetectable HIV-DNA are eligible
to the trial.

well controlled: undetectable viral RNA, CD4+ count ≥ 350, no history of
AIDS-defining opportunistic infection within the past 12 months, and stable for at
least 4 weeks on the same anti-HIV medications (meaning there are no expected
further changes in that time to the number or type of antiretroviral drugs in the
regimen). If an HIV infection meets the above criteria, monitoring of viral RNA load
and CD4+ count is recommended. Patients must be tested for HIV during the screening
period if acceptable by local regulations or an institutional review board
(IRB)/ethics committee (EC).
10. Any concurrent systemic therapy (e.g. chemotherapy, targeted therapy,
immunotherapy..), radiotherapy, investigational agent , or biological therapy for
