BI 765063: monoclonal antibody, SIRPα antagonist, a a myeloid checkpoint inhibitor.
BI 754091: monoclonal antibody, PD-1 checkpoint inhibitor.

Randomized to arm SIRPα inhibitor monotherapy or combination SIRPα inhibitor+ anti PD-1
Trial will assesses patients for SIRPα polymorphism in blood sampling (patient DNA) in a central laboratory for eligibility.
CRC explicitly mentioned in the solid tumors to treat.
Therapies that block the CD47/SIRPα axis stimulate phagocytosis of cancer cells in vitro and anti-tumour immune responses in vivo. Phagocytosis in response to CD47/SIRPα-blocking agents results in antigen uptake and presentation, thereby linking the innate and adaptive immune systems.

Inclusion Criteria

Inclusion Criteria:

Signed and dated, written informed consent form (ICF) prior to any trial-specific procedures.
Male or female aged ≥ 18 years (no upper limit of age) at the time of ICF signature.
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
Life expectancy of at least 3 months.
Patients with a SIRPα polymorphism including at least one V1 allele will be selected (i.e., homozygous V1/V1 or heterozygous V1/V2 in separate cohorts in escalation [Step 1] and only homozygous V1/V1 in expansion cohorts [Step 2]); SIRPα polymorphism will be assessed in blood sampling (patient DNA) in a central laboratory; V1 allele is understood to include V1 and V1-like alleles.

In Step 1: Patients with histologically or cytologically documented advanced/metastatic primary or recurrent malignancies who failed or are not eligible to standard therapy;

In Step 2: Cohort C1: Patients with histologically or cytologically advanced/metastatic primary or recurrent unresectable documented MSS colorectal tumors, whose disease relapsed after standard of care and who received no prior anti-PD-L1 inhibitors.

Cohort C2: Patients with histologically or cytologically advanced or metastatic documented MSS endometrial carcinoma whose disease relapsed after standard of care and who received no prior anti-PD-L1 inhibitors.

Patients with at least one measurable lesion as per RECIST v1.1.

Patients must agree to pre- and on-treatment tumor biopsies. Fresh tumor biopsy may come either from the primary tumor or from a metastasis. Cytological material is not accepted. Archival tumor biopsy is acceptable, if done within 4 weeks before the first treatment administration.

Biopsy sites should be carefully selected by the investigator so that it is safe for the patient and subsequent biopsy can be performed at the same location; also if possible should be distinct from the measurable lesion;

Adequate biological parameters defined as:

Absolute neutrophil count (ANC) ≥ 1.5 x 10^9/L.
Hemoglobin (Hb) level ≥ 10 g/dL. (without recent red blood cell transfusion within 2 weeks prior to study entry)
Platelet count ≥ 100 x 10^9/L.
Total bilirubin level ≤ 1.5 X Upper Limit Normal (ULN), except for patients with Gilbert's syndrome from whom total bilirubin < 3.0 x ULN or direct bilirubin < 1.5 x ULN is authorized. Aspartate transaminase (AST) and alanine transaminase (ALT) ≤ 2.5 x ULN. Serum creatinine ≤ 1.5 ULN; or creatinine clearance > 50 mL/min (Chronic Kidney Disease Epidemiology [CKD-EPI] formula).
INR ≤ 1.5 (except if patient treated with anti-vitamin K); anticoagulation with anti-vitamin K and Low Molecular Weight Heparin [LMWH] is allowed;
Prior major treatment-related surgery completed at least 28 days before study drug administration;

In all cohorts :

An interval of at least 28 days since the last chemotherapy, approved immunotherapy, biological or investigational therapy, radiation or tyrosine kinase inhibitor (TKI) therapy (sunitinib, sorafenib) must have elapsed before the first study drug administration(s);
And all toxicities related to previous anticancer therapies have resolved to normal value or ≤ to Grade 1 prior to the study treatment administration, except alopecia.
Women must not be breastfeeding;

Women of childbearing potential (WOCB) must agree to use highly effective methods of contraception (i.e. one that results in a less than 1% per year failure rate when used consistently and correctly), prior to study entry, during the study and for 5 months after the last dose of study drug.

Highly effective methods of contraception are defined as one of the following methods: combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal), progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable), intrauterine device (IUD), intrauterine hormone-releasing system (IUS), bilateral tubal occlusion, vasectomised partner, sexual abstinence.

Male patient with WOCBP partner must be willing to use male contraception (condoms) during the study and until 5 months after last dose of study drug. WOCBP partners of male subjects participating in the study may use hormone based contraceptives as one of the acceptable methods of contraception since they will not be receiving study drug (i.e.; oral hormonal contraception, cap, diaphragm, or sponge with spermicide).
Females of childbearing potential must have a serum negative pregnancy test within 7 days prior to first administration. Females who are postmenopausal for at least 1 year (defined as more than 12 months since last menses) or are surgically sterilized do not require this test.
Capable of understanding and complying with protocol requirements.
Patients must be affiliated to a social security system or an equivalent system.

Exclusion Criteria

Exclusion Criteria:

Patient with symptomatic/active central nervous system (CNS) metastases; Patient with previously treated brain metastases are eligible, if there is no evidence of progression for at least 28 days before the first study treatment administration, as ascertained by clinical examination and brain imaging (MRI or CT) during the screening period;
Other tumor location necessitating an urgent therapeutic intervention (e.g., palliative care, surgery or radiation therapy, such as spinal cord compression, other compressive mass, uncontrolled painful lesion, bone fracture).

Presence of other active invasive cancers, other than the one treated in this trial, within 5 years prior to screening.

Except appropriately treated basal cell carcinoma of the skin, or in situ carcinoma of uterine cervix, or other local tumors considered cured by local treatment;

Patient with active autoimmune disease or a documented history of autoimmune disease, that requires systemic treatment (i.e. corticosteroids or immunosuppressive drugs).

Except patients with vitiligo, resolved childhood asthma/atopy, alopecia, or any chronic skin condition that does not require systemic therapy, patients with autoimmune-related hypothyroidism on a stable dose of thyroid replacement hormone and/or controlled Type 1 diabetes mellitus on a stable insulin regimen may be eligible.

Known severe infusion related reactions to monoclonal antibodies (Grade ≥ 3 NCI-CTCAE v5.0) and patients removed from previous anti-PD-1 or anti-PD-L1 therapy because of a severe or life-threatening immune-related adverse event (irAE) (Grade ≥ 3 NCI-CTCAE v5.0);
Patients receiving systemic treatment with any immunosuppressive medication within one-week prior treatment start; Steroids of max. 10 mg prednisolone equivalent per day are allowed, topical and inhaled steroids are not considered as immunosuppressive.
Patients with interstitial lung disease or active, non-infectious pneumonitis.
