Niraparib Added to Anti-PD-L1 Antibody Maintenance in SLFN11-positive, Extensive-disease SCLC

Recruiting now · Phase 2

Conditions studied: SCLC,Extensive Stage, SLFN11-positive

In brief

RAISE is an international, multicentre, single-arm phase II trial. The trial treatment consists of the addition of niraparib, 200 mg orally once daily to anti-PD-L1 antibody maintenance. The primary objective of this trial is to assess the clinical efficacy of the addition of niraparib to anti-PD-L1 monoclonal antibody maintenance treatment in patients with SLFN11-positive ED-SCLC which has not progressed following standard first-line chemo-immunotherapy.

Who can join

You may qualify if…

• Inclusion criteria for SLFN11-expression testing
• Written IC part 1: for SLFN11-screening must be signed and dated by the patient and the investigator prior to sending any tumour material to the central laboratory.
• Histologically or cytologically confirmed ED-SCLC (stage IV according to the 8th TNM classification).
• Availability of FFPE tumour tissue for screening.
• Inclusion criteria for trial participation
• Written IC part 2: for trial participation must be signed and dated by the patient and the investigator prior to any trial-related intervention.
• High SLFN11-expression on FFPE tumour material:
• SLFN11-expression is determined at the central screening laboratory in Basel. Overexpression is defined as detectable protein expression by IHC in ≥20% of tumour cells.
• Patients must have received standard first-line chemo-immunotherapy, consisting of 4 cycles of platinum-etoposide chemotherapy in combination with an anti-PD-L1 antibody (atezolizumab or durvalumab). Patients who started the immunotherapy at chemotherapy cycle 2 are eligible.
• ED-SCLC must not have progressed during or after standard chemo-immunotherapy (as per RECIST v1.1).
• Patients must be candidates for ongoing maintenance treatment with immune-checkpoint inhibition.
• Adequate haematological function:
• Adequate renal function:
• Adequate liver function:
• ECOG PS 0-2
• Age ≥18 years
• Women of childbearing potential, including women who had their last menstruation in the last 2 years, must have a negative urinary or serum pregnancy test within 4 weeks before enrolment and within 3 days before treatment start.

You may not qualify if…

• Symptomatic brain metastases
• Any clinically active cancer, other than SCLC Exception: malignancies with negligible risk of metastases or death (e.g. 5-year OS rate of >90%), such as adequately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, localised prostate cancer, ductal carcinoma in situ, or stage I uterine cancer. Hormonal therapy for non-metastatic prostate or ductal carcinoma in situ is allowed.
• Consolidating thoracic radiotherapy. Palliative radiotherapy to the brain or to bones is allowed.
• History of idiopathic pulmonary fibrosis, organising pneumonia (e.g., bronchiolitis obliterans), drug-induced pneumonitis, or idiopathic pneumonitis, or evidence of active pneumonitis on screening chest computed tomography (CT) scan.
• Any lung disease requiring systemic steroids in doses of >10 mg prednisolone (or equivalent dose of other steroid).
• Any serious concomitant systemic disorders (for example active infection, unstable cardiovascular disease) which in the opinion of the investigator would compromise the patient's ability to complete the trial or interfere with the evaluation of the efficacy and safety of the protocol treatment.
• Inadequately controlled hypertension, defined as systolic blood pressure >150 mmHg and/or diastolic blood pressure >95 mmHg.
• The patient must be considered stable and hypertension medically controlled.
• History of myelodysplastic syndrome/acute myeloid leukemia (MDS/AML).
• Prior Reversible Encephalopathy Syndrome (PRES)
• Severe renal or hepatic impairment.
• Any clinically significant gastrointestinal (GI) abnormalities that may alter absorption such as malabsorption syndrome or major resection of the stomach and/or bowels.
• Treated with live vaccine within 30 days before enrolment.
• Hypersensitivity to niraparib or any of its excipients (e.g., tartrazine).
• Women who are pregnant or in the period of lactation.
• Sexually active men and women of childbearing potential who are not willing to use an effective contraceptive method during the trial and within the required timelines after last dose of niraparib treatment.
• Judgment by the investigator that the patient is unlikely to comply with trial procedures, restrictions and requirements.
