Studien-Informationen

Detailed Description:

The primary objectives of the study are to demonstrate superiority of Dato-DXd relative to

ICC by assessment of PFS in participants with locally recurrent inoperable or metastatic TNBC

who are not candidates for PD-1/PD-L1 inhibitor therapy, per BICR and to demonstrate

superiority of Dato-DXd relative to ICC by assessment of OS in participants with locally

recurrent inoperable or metastatic TNBC who are not candidates for PD-1/PD-L1 inhibitor

therapy.

Ein-/Ausschlusskriterien

Inclusion Criteria:

Age

1. Participant must be ≥ 18 years at the time of screening. Type of Participant and

Disease Characteristics

2. Histologically or cytologically documented locally recurrent inoperable TNBC, which

cannot be treated with curative intent, or metastatic TNBC. TNBC is defined as:

- Negative for ER with < 1% of tumour cells positive for ER on IHC.

- Negative for progesterone receptor with < 1% of tumour cells positive for

progesterone receptor on IHC.

negative by in situ hybridisation per the ASCO-CAP HER2 guideline

3. No prior chemotherapy or other systemic anti-cancer therapy for metastatic or locally

recurrent inoperable breast cancer.

4. Not a candidate for PD-1/PD-L1 inhibitor therapy, defined as:

- Participants whose tumours are PD-L1-negative, or

- Participants whose tumours are PD-L1-positive and have:

1. relapsed after prior PD-1/PD-L1 inhibitor therapy for early-stage breast

cancer,

2. comorbidities precluding PD-1/PD-L1 inhibitor therapy, or

3. no regulatory access to pembrolizumab [participant's country does not have

regulatory approval at the time of screening]).

5. At least 1 measurable lesion not previously irradiated that qualifies as a RECIST 1.1

TL at baseline and can be accurately measured at baseline as ≥ 10 mm in the longest

diameter (except lymph nodes, which must have short axis ≥ 15 mm) with computed

tomography (CT) or magnetic resonance imaging (MRI), and is suitable for accurate

repeated measurements.

6. ECOG PS 0 or 1 with no deterioration over the previous 2 weeks prior to baseline or

day of first dosing.

7. Eligible for one of the chemotherapy options listed as ICC (paclitaxel,

nab-paclitaxel, capecitabine, carboplatin, or eribulin), based on DFI and prior taxane

exposure, per investigator assessment.

8. Has had an adequate treatment washout period before Cycle 1 Day 1, defined as:

- Major surgery: ≥ 3 weeks.

- Radiation therapy including palliative radiation to chest: ≥ 4 weeks (palliative

radiation therapy to other areas ≥ 2 weeks).

- Corticosteroid therapy for central nervous system metastatic disease: > 3 days.

- Anti cancer therapy including hormonal therapy: ≥ 3 weeks (for small molecule

targeted agents: ≥ 2 weeks or 5 half-lives, whichever is longer).

- Nitrosoureas or mitomycin C: ≥ 6 weeks.

- Antibody-based anti cancer therapy: ≥ 4 weeks with the exception of receptor

activator of nuclear factor kappa-B ligand (RANKL) inhibitors (eg, denosumab for

the treatment of bone metastases).

times the terminal elimination half-life of the agent, whichever is longer.

- Chloroquine/hydroxychloroquine: > 14 days.

9. Written confirmation of tumour sample needs to be available prior to enrolment and

tumour samples should be available prior to randomisation. All participants must have

a FFPE metastatic (excluding bone) or locally recurrent inoperable tumour sample

(block preferred, or a minimum of 20 freshly cut slides) available, collected ≤ 3

months prior to screening. If neither an adequate FFPE block nor the minimum of 20

slides are available from the most recent biopsy, or if a biopsy is not feasible for

safety reasons, and this is clearly documented, an archival tumour specimen obtained

before the diagnosis of locally recurrent inoperable or metastatic breast cancer may

be submitted, pending approval by the Global Study Team.

10. Participants with a history of previously treated neoplastic spinal cord compression

or asymptomatic, stable brain metastases, who require no treatment with

corticosteroids or anticonvulsants may be included in the study, if they are no longer

symptomatic and have recovered from acute toxic effects of radiotherapy. A minimum of

2 weeks must have elapsed between the end of radiotherapy and Cycle 1 Day 1. A minimum

of 3 days must have elapsed between the end of corticosteroid therapy for central

nervous system metastatic disease and Cycle 1 Day 1.

11. Adequate organ and bone marrow function within 7 days before randomisation as follows:

- Haemoglobin ≥ 9.0 g/dL (red blood cell/plasma transfusion is not allowed within 1

week prior to screening assessment).

- Absolute neutrophil count ≥ 1.5 × 10^9/L (granulocyte colony stimulating factor

administration is not allowed within 1 week prior to screening assessment).

- Platelet count ≥ 100 × 10^9/L (platelet transfusion is not allowed within 1 week

prior to screening assessment).

- Total bilirubin (TBL) ≤ 1.5 × upper limit of normal (ULN) or < 3 × ULN in the

presence of documented Gilbert's syndrome (unconjugated hyperbilirubinemia).

- Except in the setting of HBV, Alanine aminotransferase (ALT) and aspartate

aminotransferase (AST) ≤ 2.5 × ULN for AST/ALT (< 5 × ULN in participants with

liver metastases). See Exclusion Criterion 5 for requirements in the setting of

HBV.

- Calculated CrCL ≥ 30 mL/minute as determined by Cockcroft Gault

12. Minimum life expectancy of 12 weeks.

Sex

13. Male or female. Contraceptive use by men or women should be consistent with local

regulations regarding the methods of contraception for those participating in clinical

studies.

Reproduction

14. Negative pregnancy test (serum) for women of childbearing potential.

15. Female participants must be at least 1 year post-menopausal, surgically sterile, or

using at least 1 highly effective form of birth control (a highly effective method of

contraception is defined as one that can achieve a failure rate of less than 1% per

year when used consistently and correctly.) Women of childbearing potential who are

sexually active with a non sterilised male partner must agree to use at least 1 highly

effective method of birth control. They should have been stable on their chosen method

of birth control for a minimum of 3 months before Cycle 1 Day 1 and continue for at

least 7 months after the last dose. Female participants must refrain from egg cell

donation or retrieval for their own use, and breastfeeding from enrolment throughout

the study and for at least 7 months after the last dose of study drug. Any non

sterilised male partner of a woman of childbearing potential must use a male condom

plus spermicide (condom alone in countries where spermicides are not approved)

throughout this period.

16. Male participants who intend to be sexually active with a female partner of

childbearing potential must be surgically sterile or use an acceptable method of

contraception from the time of screening throughout the total duration of the study

and the drug washout period (at least 6 months after the last dose of study

intervention), in addition to the female partner using a highly effective

contraceptive method, to prevent pregnancy in a partner. Male participants must not

donate or bank sperm during this same time period. Preservation of sperm should be

considered prior to randomisation. Not engaging in heterosexual activity (sexual

abstinence) for the duration of the study and drug washout period is an acceptable

practice, if this is the preferred usual lifestyle of the participant. Periodic or

occasional abstinence, the rhythm method, and the withdrawal method are not acceptable

methods of contraception.

Informed Consent

17. Capable of giving signed informed consent, which includes compliance with the

requirements and restrictions listed in the ICF and in this protocol.

18. Provision of signed and dated written Optional Genetic Research Information informed

Studien-Rationale

Primary outcome:

1. Progression Free Survival (PFS) (Time Frame - From randomization until progression as assessed by BICR or death due to any cause (anticipated to be up to 26 months)):
PFS is defined as time from randomisation until progression per RECIST 1.1 as assessed by BICR, or death due to any cause. The analysis will include all randomised participants, as randomised, regardless of whether the participant withdraws from randomised therapy, receives another anti-cancer therapy or clinically progresses prior to RECIST 1.1 progression. However, if the participant progresses or dies immediately after 2 or more consecutive missed visits, the participant will be censored at the time of the latest evaluable assessment prior to the 2 missed visits. The measure of interest is the hazard ratio [HR] of PFS.

2. Overall Survival (OS) (Time Frame - From randomisation until the date of death due to any cause (approximately 42 months)):
OS is defined as the time from randomisation until the date of death due to any cause. The analysis will include all randomised participants, by treatment group as randomised. The measure of interest is the hazard ratio [HR] of OS.

Secondary outcome:

1. Objective Response Rate (ORR) (Time Frame - From randomisation up until progression (anticipated to be up to 26 months)):
ORR is defined as the proportion of participants who have a confirmed CR or PR, as determined by BICR/investigator assessment, per RECIST 1.1. The analysis will include all randomised participants, by treatment group as randomised. Data obtained from randomisation up until progression, or the last evaluable assessment in the absence of progression, will be included in the assessment of ORR, regardless of whether the participant withdraws from therapy. Participants who go off treatment without a response or progression, receive a subsequent anti-cancer therapy, and then respond will not be included as responders in the ORR. The measure of interest is the odds ratio of the ORR.

2. Duration of Response (DoR) (Time Frame - From the date of first documented confirmed response until date of documented progression per RECIST 1.1, as assessed by BICR/investigator assessment or death due to any cause (anticipated to be up to 26 months)):
DoR is defined as the time from the date of first documented confirmed response until date of documented progression per RECIST 1.1, as assessed by BICR/investigator assessment or death due to any cause. The analysis will include all randomised participants as randomised who have a confirmed response, regardless of whether the participant withdraws from therapy, receives another anti-cancer therapy or clinically progresses prior to RECIST 1.1 progression. The measure of interest is the median of DoR,

3. Progression-Free Survival (PFS) by Investigator assessment (Time Frame - From randomisation until progression per RECIST 1.1 as assessed by the investigator, or death due to any cause (anticipated to be up to 26 months)):
PFS is defined as time from randomisation until progression per RECIST 1.1 as assessed by the investigator, or death due to any cause. The analysis will include all randomised participants, as randomised, regardless of whether the participant withdraws from randomised therapy, receives another anti-cancer therapy or clinically progresses prior to RECIST 1.1 progression. The measure of interest is the hazard ratio [HR] of PFS.

4. Disease Control Rate (DCR) (Time Frame - At least 11 weeks after randomization to 23 months):
DCR at 12 weeks is defined as the percentage of participants who have a confirmed CR or PR or who have SD, per RECIST 1.1, as assessed by BICR/investigator assessment and derived from the raw tumour data for at least 11 weeks after randomisation. The analysis will include all randomised participants by treatment group as randomised. Data obtained from randomisation up until progression, or the last evaluable assessment in the absence of progression, will be included in the assessment of DCR, regardless of whether the participant withdraws from therapy. Participants who receive a subsequent anticancer therapy prior to Week 11 will not be considered to have disease control in the analysis. The measure of interest is the odds ratio of the DCR.

5. Time to deterioration (TTD) in pain in participants treated with Dato DXd compared with ICC (Time Frame - From the date of randomisation to the date of deterioration (from randomization to 18 weeks post-progression)):
TTD in pain as measured by the pain scale from EORTC IL146. TTD is defined as time from the date of randomisation to the date of deterioration. Deterioration is defined as change from baseline that reaches a clinically meaningful deterioration threshold. The analysis will include all randomised participants. The measure of interest is the hazard ratio [HR] of TTD in pain.

6. Time to deterioration (TTD) in physical functioning in participants treated with Dato DXd compared with ICC (Time Frame - From the date of randomisation to the date of deterioration (from randomization to 18 weeks post-progression)):
TTD in physical functioning as measured by the physical functioning scale from EORTC IL146. TTD is defined as time from the date of randomisation to the date of deterioration. Deterioration is defined as change from baseline that reaches a clinically meaningful deterioration threshold. The analysis will include all randomised participants. The measure of interest is the hazard ratio [HR] of TTD in physical functioning.

7. Time to deterioration (TTD) in breast and arm symptoms in participants treated with Dato DXd compared to ICC (Time Frame - From the date of randomisation to the date of deterioration (from randomization to 18 weeks post-progression)):
TTD in breast symptoms as measured by the breast symptoms scale from EORTC IL116 TTD in arm symptoms as measured by the arm symptoms scale from EORTC IL116 TTD is defined as time from the date of randomisation to the date of deterioration. Deterioration is defined as change from baseline that reaches a clinically meaningful deterioration threshold. The analysis will include all randomised participants. The measure of interest is the hazard ratio [HR] of TTD in breast symptoms/arm symptoms.

8. Time to deterioration (TTD) in GHS/QoL in participants treated with Dato DXd compared with ICC (Time Frame - From the date of randomisation to the date of deterioration (from randomization to 18 weeks post-progression)):
TTD in GHS/QoL as measured by the GHS/QoL scale from EORTC IL146. TTD is defined as time from the date of randomisation to the date of deterioration. Deterioration is defined as change from baseline that reaches a clinically meaningful deterioration threshold. The analysis will include all randomised participants. The measure of interest is the hazard ratio [HR] of TTD in GHS/QoL.

9. Time to First Subsequent Therapy (TFST) (Time Frame - From randomisation until the start date of the first subsequent anti-cancer therapy after discontinuation of randomised treatment, or death due to any cause (anticipated to be up to 26 months)):
TFST is defined as the time from randomisation until the start date of the first subsequent anti-cancer therapy after discontinuation of randomised treatment, or death due to any cause. The analysis will include all randomised participants as randomised, regardless of progression status. The measure of interest is the hazard ratio [HR] of TFST.

10. Time to Second Subsequent Therapy (TSST) (Time Frame - From randomisation until the start date of the second subsequent anti cancer therapy after discontinuation of first subsequent treatment, or death due to any cause (anticipated to be up to 26 months)):
TSST is defined as the time from randomisation until the start date of the second subsequent anti cancer therapy after discontinuation of first subsequent treatment, or death due to any cause. The analysis will include all randomised participants as randomised, regardless of progression status on study treatment or first subsequent treatment. The measure of interest is the hazard ratio [HR] of TSST.

11. Progression Free Survival 2 (PFS2) (Time Frame - From randomisation to the earliest of the progression event (following the initial progression), subsequent to first subsequent therapy, or death (anticipated to be up to 26 months)):
PFS2 will be defined as the time from randomisation to the earliest of the progression event (following the initial progression), subsequent to first subsequent therapy, or death. The date of second progression will be recorded by the investigator in the eCRF and defined according to local standard clinical practice. The analysis will include all randomised participants as randomised regardless of whether the participant withdraws from subsequent therapy and regardless of missed visits. The measure of interest is the hazard ratio [HR] of PFS2.

12. Pharmacokinetics of Dato-DXd (Time Frame - From first dose to end of treatment (anticipated to be up to 26 months)):
Concentration of Dato DXd, total anti-TROP2 antibody, and MAAA-1181a in plasma.

13. Immunogenicity of Dato-DXd (Time Frame - From first dose to end of treatment safety follow-up (anticipated to be up to 26 months)):
Presence of ADAs for Dato-DXd (confirmatory results: positive or negative, titres).

14. Safety of Dato-DXd (Time Frame - From first dose to end of treatment safety follow-up (anticipated to be up to 26 months)):
Safety will be evaluated in terms of AEs (graded by CTCAE version 5.0)
