Palliative Radiotherapy With Lurbinectedin in Patients With Extensive Stage Small Cell Lung Cancer

Recruiting now · Phase 1

Conditions studied: Extensive Stage Lung Small Cell Carcinoma, Stage IV Lung Cancer AJCC v8

In brief

This phase I trial aims to determine if it is safe to use palliative radiotherapy and lurbinectedin at the same time to treat small cell lung cancer that has spread outside of the chest and that has grown after being treated with chemotherapy (extensive stage). Lurbinectedin kills tumor cells by blocks a process called transcription that small cell lung cancer relies on to survive. It also damages the deoxyribonucleic acid (DNA) of tumor cells, which is similar to the way radiation kills tumor cells. Palliative radiotherapy is a routine medical treatment for patients who have lung cancer that has spread to other parts of the body (metastatic), and is used to relieve symptoms caused by cancer or to patients from developing symptoms. This trial may help doctors understand if treating patients with lurbinectedin and palliative radiotherapy at the same time would make them both work better than either one alone or if they could cause more side effects for patients when given together.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Age >= 18 years
Eastern Cooperative Oncology Group (ECOG) performance status =< 3
Patients with pathologically confirmed ES-SCLC who are receiving lurbinectedin or are candidates for lurbinectedin therapy after progression on first-line systemic therapy (either chemotherapy [platinum etoposide] or chemoimmunotherapy) at the discretion of the treating medical oncologist.
Metastatic bone or visceral/lung metastatic disease as assessed computed tomography (CT), magnetic resonance imaging (MRI), bone scan or positron emission tomography (PET)/CT within 90 days prior to RT on this study.
Patients with treated brain metastases are eligible but must require < 10 mg of dexamethasone daily or its glucocorticoid equivalent. Brain metastases will not be treated in the context of this protocol.
Absolute neutrophil count (ANC) >= 1,500/cells/mm\^3
Platelets >= 100,000/cells/mm\^3
Hemoglobin > 7.0 g/dL
Total Bilirubin ≤ 1.5 ULN
Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) =< 3.0 x ULN (=< 5.0x ULN for liver involvement)
Alkaline phosphatase =< 2.5x ULN (=< 5.0x with documented liver or bone metastases)
Based on its mechanism of action, lurbinectedin could cause harm when administered to a pregnant woman. Taken together with the known teratogenicity of RT, female of child-bearing potential (FCBP) must have a negative serum or urine pregnancy test prior to starting protocol therapy. A female of childbearing potential (FCBP) is a sexually mature woman who: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months.
FCBP and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation and 6 months after the final dose of lurbinectedin. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of lurbinectedin administration. FCBP who are currently breastfeeding must discontinue during and up to 2 weeks after the final dose of lurbinectedin.
Completion of all previous cancer-directed therapies (excluding lurbinectedin) for the treatment of cancer >= 3 weeks before the start of study therapy.
Willingness and ability of the subject to comply with scheduled visits, drug administration plan, protocol-specified laboratory tests, other study procedures, and study restrictions.
Evidence of a personally signed informed consent indicating that the subject is aware of the neoplastic nature of the disease and has been informed of the procedures to be followed, the experimental nature of the therapy, alternatives, potential risks and discomforts, potential benefits, and other pertinent aspects of study participation.

You may not qualify if…

An individual who meets any of the following criteria will be excluded from participation in this study:
Pregnancy or breastfeeding within 2 weeks
Patients may not enroll in both safety cohorts
Patients who have received prior RT will be permitted to enroll. However, the metastases treated on this study must be > 2 cm from the following previously irradiated structures:
Spinal cord previously irradiated to > 40 Gy (delivered in =< 3Gy/fraction)
Brachial plexus previously irradiated to > 50Gy (delivered in =< 3Gy/fraction)
Small intestine, large intestine, or stomach previously irradiated to > 45Gy (delivered in =< 3Gy/fraction)
Brainstem previously irradiated to > 50Gy (delivered in =< 3Gy/fraction)
Lungs previously irradiated with prior V20Gy > 35 percent (delivered in =< 3Gy/fraction)
