DANTE FLOT8 - Eine randomisierte, offene Phase-II/III-Studie zur Wirksamkeit und Sicherheit von Atezolizumab in Kombination mit FLOT versus FLOT allein bei Patienten mit Magenkrebs und Adenokarzinom des ösophagogastralen Übergangs und hoher Immunreaktivität (MO30039/MO43340) – Die DANTE Studie

Descrizione riassuntiva della sperimentazione (Fonte di dati: BASEC)

Die DANTE Studie ist eine multizentrische, multinationale Studie (Deutschland, Schweiz). Sie untersucht die die Wirksamkeit und Verträglichkeit der Studienmedikation (Studienarm A) Atezolizumab in Kombination mit FLOT (bestehend aus den Medikamenten 5-Fluorouracil (5-FU), Folinsäure, Oxaliplatin und Docetaxel) zur Vor- und Nachbehandlung des Magentumors oder des Tumors der unteren Speiseröhre. Verglichen wird diese neue Kombination mit der Standardtherapie (Studienarm B) FLOT vor, während und nach der Operation. Patienten werden 1:1 randomisiert, das heisst, Sie haben eine 50% Wahrscheinlichkeit in den Studienarm A oder 50% in den Studienarm B zu kommen. Wir machen diese Studie, um zu prüfen, ob durch die Hinzunahme des Antikörpers Atezolizumab, die Zeit bis zum Fortschreiten oder Wiederauftreten des Tumors verlängert werden kann oder ob es auch langfristig bei mehr Patienten zu gar keinem Rückfall mehr kommt.

Inclusion/Exclusion Criteria (Fonte di dati: WHO)

Gender: All
Maximum age: N/A
Minimum age: 18 Years

Inclusion Criteria:

1. Have provided written informed consent

2. In the investigator's judgement, is willing and able to comply with the study protocol
including the planned surgical treatment

3. Female and male patients* = 18 years of age

4. Diagnosed with histologically confirmed adenocarcinoma of the GEJ (Type I-III) or the
stomach (cT2, cT3, cT4, any N category, M0), or (any T, N+, M0) that:

1. is not infiltrating any adjacent organs or structures by CT or MRI evaluation

2. does not involve peritoneal carcinomatosis

3. is considered medically and technically resectable Note: the absence of distant
metastases must be confirmed by CT or MRI of the thorax and abdomen, and, if
there is clinical suspicion of osseous lesions, a bone scan. If peritoneal
carcinomatosis is suspected clinically, its absence must be confirmed by
laparoscopy. Diagnostic laparoscopy is mandatory in patients with T3 or T4 tumors
of the diffuse type histology in the stomach or upon request of the central
review.

5. No prior cytotoxic or targeted therapy

6. No prior partial or complete esophagogastric tumor resection

7. ECOG = 1

8. Phase II only: Availability of a representative tumor specimen that is suitable for
determination of PD-L1 and MSI status; MSI assessment will be performed locally or
centrally, and result must be available prior to randomization (for details, see
chapter 9). PD-L1 will be assessed centrally but is not used for enrolment of the
patients. The analysis requires paraffin embedded biopsy samples of the tumor.

Phase III only: Assessment of MSI and PD-L1 [and optional TMB/EBV] must be performed
locally and results for either of the following MSI-high, PD-L1 CPS=1, TMB =10/MB or
EBV+ must be available prior to randomization (for details, see chapter 9).

9. Females of childbearing potential must agree to remain abstinent (refrain from
heterosexual intercourse) or use contraceptive methods that result in a failure rate
of <1% per year during the treatment period and for at least 5 months after the last
study treatment. A woman is considered to be of childbearing potential if she is
postmenarcheal, has not reached a postmenopausal state (has not had =12 continuous
months of amenorrhea with no identified cause other than menopause), and has not
undergone surgical sterilization (removal of ovaries and/or uterus). Examples of
contraceptive methods with a failure rate of < 1% per year include bilateral tubal
ligation, male sterilization, hormonal implants, established, proper use of combined
oral or injected hormonal contraceptives, and certain intrauterine devices. The
reliability of sexual abstinence should be evaluated in relation to the duration of
the clinical trial and the preferred and usual lifestyle of the patient. Periodic
abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and
withdrawal are not acceptable methods of contraception.

Males must agree to remain abstinent (refrain from heterosexual intercourse) or use
contraceptive measures, and agree to refrain from donating sperm, as defined below:

a. With female partners of childbearing potential or pregnant female partners, men
must remain abstinent or use a condom plus an additional contraceptive method that
together result in a failure rate of 1% per year during the treatment period and for
at least 3 months after the last dose of study treatment to avoid exposing the embryo.
Men must refrain from donating sperm during this same period. Men with a pregnant
partner must agree to remain abstinent or to use a condom for the duration of the
pregnancy.

10. Criterion integrated in criterion 9.

11. Adequate hematological, hepatic and renal function as indicated by the following
parameters:

- Leukocytes = 3.000/mm?, platelets = 100.000/mm3without transfusion, absolute
neutrophil count (ANC) = 1500/mm3without granulocyte colony-stimulating factor
support, Hemoglobin = 90 g/L (9 g/dL) - Patients may be transfused to meet this
criterion.

- Bilirubin = 1.5 x upper limit of normal, aspartate transaminase and alanine
transaminase = 2.5 x upper limit of normal, alkaline phosphatase = 2.5 x upper
limit of normal

- Serum creatinine = 1.5 x upper limit of normal, or glomerular filtration rate >
45 ml/min (calculated using the Cockcroft-Gault formula)

- Serum albumin = 25 g/L (2.5 g/dL)

- For patients not receiving therapeutic anticoagulation: INR or aPTT = 1.5 x ULN;
for patients receiving therapeutic anticoagulation: stable anticoagulant regimen
*There are no data that indicate special gender distribution. Therefore, patients
will be enrolled in the study gender-independently.

Exclusion Criteria:

1. History of severe allergic, anaphylactic, or other hypersensitivity reactions to
chimeric or humanized antibodies or fusion protein; Known hypersensitivity to Chinese
hamster ovary cell products or to any component of the atezolizumab formulation

2. Any known contraindication (including hypersensitivity) to docetaxel, 5-FU,
leucovorin, or oxaliplatin.

3. Active or History of autoimmune disease including, but not limited to, myasthenia
gravis, myositis, autoimmune hepatitis, systemic lupus erythematosus, rheumatoid
arthritis, inflammatory bowel disease, antiphospholipid antibody syndrome, Wegener's
granulomatosis, Sj?gren's syndrome, Guillain-Barr? syndrome, multiple sclerosis,
vasculitis, or glomerulonephritis. Note: History of autoimmune-related hypothyroidism
on a stable dose of thyroid replacement hormone, or controlled Type 1 diabetes
mellitus on a stable insulin regimen may be eligible based on consultation with the
sponsor's medical monitor. Patients with eczema, psoriasis, lichen simplex chronicus,
or vitiligo with dermatologic manifestations only (e.g., patients with psoriatic
arthritis are excluded) are eligible for the study provided all of following
conditions are met:

- Rash must cover < 10% of body surface area

- Disease is well controlled at baseline and requires only low-potency topical
corticosteroids

- No occurrence of acute exacerbations of the underlying condition requiring
psoralen plus ultraviolet A radiation, methotrexate, retinoids, biologic agents,
oral calcineurin inhibitors, or high potency or oral corticosteroids within the
previous 12 mo
