-
Histologically or cytologically confirmed extensive stage small cell lung cancer without prior specific systemic therapy aside from induction with platinum, etoposide, and atezolizumab. Measurable disease is not required for eligibility.
-
Receipt of at least 3 cycles (and no more than 4 cycles) of platinum plus etoposide and atezolizumab during the induction phase, without tumor progression as determined by CT scan and brain MRI. Patients should be able to start the study treatment no more than 6 weeks from the last dose of induction chemo/immunotherapy. This period may be extended to 8 weeks in patients requiring brain radiotherapy after completion of induction chemo/immunotherapy for brain metastases.
-
At least 18 years of age.
-
ECOG performance status ≤ 1
-
Normal bone marrow and organ function as defined below:
- Absolute neutrophil count ≥ 1.5 K/cumm
- Platelets ≥ 100 K/cumm

- AST(SGOT)/ALT(SGPT) ≤ 2.5 x IULN (≤ 5 x IULN for patients with liver metastases)

- Urine protein ≤ 1+ or urine protein to creatinine ratio ≤ 1; if UPC ratio is > 1 on urinalysis, then 24-hour urine collection for protein must be obtained and level must be < 1,000 mg for patient enrollment

-
Patients receiving therapeutic non-Coumadin anticoagulation are eligible, provided they are on a stable dose (per investigator judgment) of anticoagulant.
-
The effects of atezolizumab and vorolanib on the developing human fetus are unknown. For this reason, women of childbearing potential 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. Should a woman become pregnant or suspect she is pregnant while participating in this study, she must 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 the study, and 31 weeks after last dose of study treatment. Women must use birth control for at least 31 weeks after last dose of study treatment. Women must not be breastfeeding.
-
Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable).

- Gastrointestinal perforation, and/or fistula, or risk factors for perforation within 6 months prior to enrollment.
- Grade 3 or 4 gastrointestinal bleeding within 3 months prior to enrollment.
- History of active autoimmune disease, including but not limited to systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, vascular thrombosis associated with antiphospholipid syndrome, Wegener's granulomatosis, Sjögren's syndrome, Bell's palsy, Guillain-Barré syndrome, multiple sclerosis, vasculitis, or glomerulonephritis.
- History of idiopathic pulmonary fibrosis, pneumonitis (including drug-induced), organizing pneumonia (i.e., bronchiolitis obliterans, cryptogenic organizing pneumonia, etc.), or evidence of active pneumonitis on screening chest CT scan.
- Hemoptysis (defined as bright red blood or ≥ ½ teaspoon) within 28 days prior to Cycle 1 Day 1 or with radiographic evidence of intratumor cavitation or radiologically documented evidence of major blood vessel invasion or encasement by cancer.
- Serious or non-healing wound, ulcer, or bone fracture within 28 days prior to Cycle 1 Day 1.
- Undergone major surgery within 28 days prior to Cycle 1 Day 1, or minor surgery/subcutaneous venous access device placement within 7 days prior to Cycle 1 Day 1, or has elective or planned major surgery to be performed during the course of the clinical trial.

- Primary Outcome Measures
Name Time Method Kaplan Meier Estimate of Progression-free Survival at 6 Months 6 months * Progression-free survival is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first.
* Progressive disease (PD): At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study.) In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression.)
* Kaplan-Meier product limit estimator will be used to estimate progression-free survival (PFS) at 6 months, with the inclusion of 90% confidence interval.
- Secondary Outcome Measures
Name Time Method Progression-free Survival Up to 3 years post start of treatment (up to 5 years) * Progression-free survival is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first. Subjects lost to follow-up will be excluded from the analysis.
* Progressive disease (PD): At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study.) In addition to he relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression.)Safety and Tolerability of Treatment Regimen as Measured by the Number of Participants With Adverse Events From the start of treatment until 90 days after completion of treatment (up to 27 months). The descriptions and grading scales found in the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 will be utilized for all toxicity reporting.
Overall Survival Up to 3 years post start of treatment (up to 5 years) Overall survival is defined as the length of time from the start of study treatment that patients diagnosed with the disease are still alive. Kaplan-Meier product limit estimator will be used to estimate the overall survival rate.
