Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
I. To compare the progression-free survival (PFS) between the combination of iadademstat plus immune checkpoint inhibitor (ICI) versus ICI maintenance alone.
SECONDARY OBJECTIVES:
I. To compare objective response rate (ORR) and overall survival (OS) between treatment arms.
II. To evaluate the safety of combination iadademstat plus ICI.
EXPLORATORY OBJECTIVES:
I. To assess whether detection of circulating tumor deoxyribonucleic acid (DNA) (ctDNA) minimal residual disease correlates with disease progression.
II. To assess whether iadademstat impacts the correlation of ICI (atezolizumab or durvalumab) baseline and time varying clearance with clinical outcomes (PFS and OS) and the presence of cachexia.
III. To explore exposure response relationships of iadademstat in combination with ICIs.
IV. To characterize changes to small cell lung cancer (SCLC) subtype throughout treatment.
OUTLINE: This is a phase I dose-escalation study of iadademstat in combination with atezolizumab and durvalumab followed by a randomized phase II study.
PHASE I: Patients receive iadademstat orally (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 intravenously (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.
PHASE II: Patients are randomized to 1 of 2 arms.
ARM I: Patients 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.
ARM II: Patients 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.
All patients also undergo multi-gated acquisition (MUGA) or echocardiogram (ECHO), brain magnetic resonance imaging (MRI) or brain computed tomography (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.
After completion of study treatment, patients are followed up every 3 months for up to 12 months.

* Albumin ≥ 3 g/dL
* Total bilirubin ≤ 1.5 institutional upper limit of normal (ULN)
* Aspartate aminotransferase (AST)(serum glutamic oxaloacetic transaminase \[SGOT\])/ alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase \[SGPT\]) ≤ 3 × institutional ULN unless liver metastases are present, in which case it must be ≤ 5 × ULN
* Glomerular filtration rate (GFR) ≥ 45 mL/min
* Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial
* For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated
* Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load

* Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial
* Evidence of post-menopausal status or negative urinary or serum pregnancy test for female pre-menopausal patients. Pregnant women are excluded from this study because atezolizumab and durvalumab are monoclonal antibody agents with the potential for teratogenic or abortifacient effects. Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply:
* Women \< 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy).
* Women ≥ 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses \>1 year ago, had chemotherapy-induced menopause with last menses \> 1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy)
* The effects of iadademstat, atezolizumab, and durvalumab on the developing human fetus are unknown. For this reason and because monoclonal antibody agents are known to be teratogenic, women of child-bearing potential and males with females of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to registration, for the duration of study participation, and for 150 days after the last dose of study medication. 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.
* Females of childbearing potential must agree to:
* Use effective contraception during the trial and 150 days after the end of treatment.
* Practice true abstinence during the trial and 150 days after the end of treatment.
* Have a negative urine pregnancy test at screening.
* Not to donate or freeze egg(s) during the course of this study or within 150 days after receiving their last dose of study drug.
* Male patients even if surgically sterilized (i.e., status post-vasectomy) must agree to:
* Use effective contraception during the entire study treatment period and through 150 days after the last dose of study drug.
* Not to donate or freeze sperm during the course of this study or within 150 days after receiving their last dose of study drug.
* Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with atezolizumab and durvalumab, female participants who are breastfeeding must agree to discontinue breastfeeding. These potential risks may also apply to iadademstat
* Ability to understand and the willingness to sign a written informed consent document. Legally authorized representatives may sign and give informed consent on behalf of study participants
* Patients with grade ≥ 2 neuropathy will be evaluated on a case-by-case basis after consultation with the study physician

* Treatment with systemic immunostimulatory agents (including, but not limited to, interferon \[IFN\]-α or interleukin \[IL\]-2) within 4 weeks or five half-lives of the drug (whichever is longer) prior to cycle 1, day 1
* Treatment with systemic immunosuppressive medications (including, but not limited to, prednisone, cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-tumor necrosis factor \[anti-TNF\] agents) within 2 weeks prior to registration or anticipation of need for systemic immunosuppressive medication during study treatment, with the following exceptions:
* Patients who have received acute, low dose, systemic immunosuppressant medications or one-time pulse dose of systemic immunosuppressant medication (e.g., 48 hours of corticosteroids for a contrast allergy) are eligible after Principal Investigator confirmation has been obtained.
* Patients who have received mineralocorticoids (e.g., fludrocortisone), corticosteroids for chronic obstructive pulmonary disease (COPD) or asthma, or low-dose corticosteroids for orthostatic hypotension or adrenocortical insufficiency are eligible
* History of allergic reactions attributed to compounds of similar chemical or biologic composition to iadademstat, atezolizumab, or durvalumab. In particular, a history of severe allergic, anaphylactic, or other hypersensitivity reactions to chimeric antibodies, fusion proteins, or Chinese hamster ovary cell products or to any component of the atezolizumab formulation
* Atezolizumab Concomitant Medication Considerations: Patients are not allowed to receive immunostimulatory agents, immunosuppressive medications, or herbal and natural remedies
* Durvalumab Concomitant Medication Considerations: Patients are not allowed to receive immunosuppressive medications, EGFR TKIs, or herbal and natural remedies
* Iadademstat Concomitant Medication Considerations: Patients are not allowed to receive prophylactic hematopoietic colony stimulating factors, any complementary or alternative medicine \[any of various systems of healing or treating disease (as non-prescription drugs, herbal medicine and homeopathy)\]. Use of these types of treatments must be terminated 1 week prior to registration
* History of allogenic organ transplantation
* Patients with active tuberculosis (TB)
* Patients with uncontrolled intercurrent illness or any other significant condition(s) that would make participation in this protocol unreasonably hazardous
