Brief Summary
This phase I/II trial tests the safety, side effects, and best dose of iadademstat when given together with atezolizumab or durvalumab, and studies the effect of the combination in treating patients with small cell lung cancer that has spread outside of the lung in which it began or to other parts of the body (extensive stage) who initially received standard of care chemotherapy and immunotherapy. Iadademstat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as atezolizumab or durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Adding iadademstat to either atezolizumab or durvalumab may be able to stabilize cancer for longer than atezolizumab or durvalumab alone in treating patients with extensive stage small cell lung cancer.

Study Arms (3)
Phase I (iadademstat, atezolizumab, durvalumab)
EXPERIMENTALPatients in Phase I receive iadademstat PO on days 1, 8, 15, and 22 or days 1 and 15 of each cycle. Patients also continue receiving their initial ICI treatment, either atezolizumab IV over 30-60 minutes on day 1 of each cycle or durvalumab IV over 60 minutes on day 1 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo MUGA or ECHO, brain MRI or brain CT during screening, and CT scans and blood and urine sample collection throughout the trial. Patients may also undergo an optional tumor biopsy on study.
Phase II Arm II (atezolizumab, durvalumab)
ACTIVE COMPARATORPatients in Phase II Arm II continue receiving their initial ICI treatment, either atezolizumab IV over 30-60 minutes on day 1 of each cycle or durvalumab IV over 60 minutes on day 1 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo MUGA or ECHO, brain MRI or brain CT during screening, and CT scans and blood and urine sample collection throughout the trial. Patients may also undergo an optional tumor biopsy on study.
Phase II, Arm I (iadademstat, atezolizumab, durvalumab)
EXPERIMENTALPatients in Phase II Arm I receive iadademstat PO on days 1, 8, 15, and 22 or days 1 and 15 of each cycle. Patients also continue receiving their initial ICI treatment, either atezolizumab IV over 30-60 minutes on day 1 of each cycle or durvalumab IV over 60 minutes on day 1 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo MUGA or ECHO, brain MRI or brain CT during screening, and CT scans and blood and urine sample collection throughout the trial. Patients may also undergo an optional tumor biopsy on study.

Eligibility Criteria
You may qualify if:
- Patients must have histologically or cytologically confirmed small cell lung cancer (SCLC)
- Patients who have been treated with platinum etoposide chemotherapy plus either atezolizumab or durvalumab immunotherapy for at least 4 cycles, and no more than 6 cycles, with either a radiographic response or stable disease. Patients are eligible if a maximum of 2 cycles of atezolizumab or durvalumab were omitted with initial treatment
- Age ≥ 18 years. Because no dosing or adverse event data are currently available on the use of iadademstat in combination with atezolizumab and durvalumab in patients \<18 years of age, children are excluded from this study
- Body weight ≥ 50 kg
- Patient is able to swallow oral medications
- Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2 (Karnofsky ≥ 60%). This assessment for eligibility will take place after patients have received 4 cycles of standard of care (SOC) chemotherapy-ICI
- Leukocytes ≥ 2,000/mcL
- Lymphocyte count ≥ 500/mcL
- Absolute neutrophil count ≥ 1,500/mcL
