Testing the Addition of an Anti-cancer Drug, Entinostat, to the Usual Chemotherapy and Immunotherapy Treatment (Atezolizumab, Carboplatin and Etoposide) for Previously Untreated Aggressive Lung Cancer That Has Spread
Study Details
Study Description
Brief Summary
This phase I trial seeks to find out the best dose, possible benefits and/or side effects of entinostat in combination with atezolizumab, carboplatin and etoposide for the treatment of previously untreated aggressive lung cancer that has spread (extensive-stage small cell lung cancer). Entinostat and etoposide may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Carboplatin is a chemotherapy drug that attaches to deoxyribonucleic acid (DNA) and may kill tumor cells. Giving entinostat in combination with atezolizumab, carboplatin and etoposide may work better than atezolizumab, carboplatin and etoposide alone.

Detailed Description
PRIMARY OBJECTIVES:
-
To determine the maximum tolerated dose (MTD) of entinostat in combination with carboplatin, etoposide, and atezolizumab.
-
To determine safety and tolerability of adding entinostat to carboplatin / etoposide / atezolizumab for extensive-stage small cell lung cancer (ES-SCLC).
-
To determine the feasibility of administering entinostat concomitantly with atezolizumab, carboplatin, and etoposide as determined by the proportion of patients who receive 3 or more cycles of the combination.
SECONDARY OBJECTIVES:
- To observe and record anti-tumor activity. II. To determine the proportion of patients who are alive and without disease progression at 9 months (9 month progression free survival [PFS]) after starting entinostat, carboplatin, etoposide, and atezolizumab.
EXPLORATORY OBJECTIVES:
-
To estimate the clinical activity of entinostat plus carboplatin/etoposide/atezolizumab as determined by response rate (RR), progression free survival (PFS), and overall survival (OS).
-
To explore the prevalence of cyclic adenosine monophosphate (cAMP) response element binding protein (CREB) binding protein (CREBBP)/ histone acetyltransferase p300 (EP300) mutations in newly diagnosed ES-SCLC population.
-
To explore the relationship between CREBBP/EP300 mutations and clinical outcomes.
-
To explore immune biomarkers that may predict response to atezolizumab and entinostat and changes in these biomarkers over the course of study treatment.
-
To explore entinostat exposure-response relationships with toxicity and clinical outcomes (PFS and OS).
-
To evaluate baseline atezolizumab clearance as an early biomarker for OS and to assess the relationship between atezolizumab time-varying clearance, cachexia and clinical outcomes (PFS and OS).
OUTLINE: This is a dose-escalation study of entinostat.
INDUCTION THERAPY: Patients receive carboplatin intravenously (IV) over 30-60 minutes on day 1, etoposide IV over 60 minutes on days 1-3, atezolizumab IV over 30-60 minutes on day 1, and entinostat orally (PO) on days 1, 8, and 15. Treatment repeats every 21 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity.
MAINTENANCE THERAPY: Patients receive atezolizumab IV over 30 minutes on day 1 and entinostat PO on days 1, 8, and 15. Treatment repeats every 21 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days, every 3 months for 2 years, then every 6 months for 3 years.

Outcome Measures
Primary Outcome Measures
- Maximum tolerated dose (MTD) [Up to 21 days]
The Bayesian optimal interval (BOIN) design will be used to find the MTD based on safety.
- Grade 3/4 adverse event rate [Up to 30 days]
Defined by Common Terminology Criteria for Adverse Events version 5.0. Will be summarized by frequency and magnitude.
- Number of cycles received of the combination of entinostat, atezolizumab, carboplatin, and etoposide [Up to cycle 4 (1 cycle = 21 days)]
The proportion of participants who receive 3 or more cycles of the combination, will be calculated with a 90% confidence interval.
Secondary Outcome Measures
- 9-month progression free survival (PFS) rate [9 months from study enrollment]
Defined as the proportion of patients alive and without disease progression. Will be estimated with a 90% confidence interval. The Kaplan Meier estimator will be used to estimate survival curves.

To be eligible for this trial, patients should be class II or better
-
The effects of entinostat on the developing human fetus are unknown. For this reason and because histone deacetylase inhibitor (HDACi) agents as well as other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, up to 5 months after the last dose of study treatment. 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 5 months after completion of study treatment
-

-
Patients with uncontrolled intercurrent illness
-

-
Pregnant women are excluded from this study because entinostat is HDACi agent with the potential for teratogenic or abortifacient effects and because of known teratogenic and abortifacient effects of cisplatin and etoposide. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with entinostat, and known risks with cisplatin and etoposide, breastfeeding should be discontinued if the mother is treated with entinostat. These potential risks may also apply to other agents used in this study
