A Phase IB and Randomized Open-Label Phase II Study of Berzosertib (M6620, VX-970) in Combination With Carboplatin/Gemcitabine/Pembrolizumab in Patients With Chemotherapy-Naïve Advanced Non-Small Cell Lung Cancer of Squamous Cell Histology
Description
Brief Summary
This phase Ib/II trial studies the best dose of carboplatin when given together with
berzosertib, gemcitabine and pembrolizumab and to see how well it works in treating patients
with stage IV squamous cell non-small cell lung cancer that has spared to other placed in the
body (advanced). Berzosertib may stop the growth of tumor cells by blocking some of the
enzymes needed for cell growth. Chemotherapy drugs, such as carboplatin and gemcitabine, work
in different ways to stop the growth of tumor cells, either by killing the cells, by stopping
them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal
antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and
may interfere with the ability of tumor cells to grow and spread. Giving berzosertib together
with carboplatin, gemcitabine, and pembrolizumab may work better in treating patients with
squamous cell non-small cell lung cancer compared to carboplatin, gemcitabine, and
pembrolizumab alone.
Detailed Description
I. To determine the recommended phase 2 dose (RP2D) of carboplatin in combination with
berzosertib (M6620) and gemcitabine/pembrolizumab, in patients with squamous cell non-small
cell lung cancer (Sq-NSCLC). (Lead-in Phase 1B) II. To compare progression-free survival
(PFS) of carboplatin/gemcitabine/pembrolizumab with and without berzosertib (M6620, VX-970)
in patients with Sq-NSCLC, as measured by a hazard ratio in an intent-to-treat analysis.
(Phase 2)
SECONDARY OBJECTIVES:
I. To compare progression-free survival (PFS) of carboplatin/gemcitabine/pembrolizumab with
and without berzosertib (M6620, VX-970) in patients with Sq-NSCLC, as measured by a hazard
ratio in an as-treated analysis.
II. To compare PFS of carboplatin/gemcitabine/pembrolizumab with and without berzosertib
(M6620, VX-970) in patients with ataxia telangiectasia mutated (ATM)-deficient Sq-NSCLC, as
measured by a hazard ratio.
III. To compare overall survival (OS) and overall response rate (ORR) of
carboplatin/gemcitabine/pembrolizumab with and without berzosertib (M6620, VX-970), in
patients with chemotherapy-naive Sq-NSCLC.
IV. To determine the systemic drug exposure of berzosertib (M6620, VX-970) and gemcitabine,
as correlates of efficacy and toxicity.
V. To determine the safety and tolerability of berzosertib (M6620, VX-970) in combination
with carboplatin/gemcitabine/pembrolizumab.
VI. To observe and record anti-tumor activity.
EXPLORATORY OBJECTIVES:
I. To identify molecular subpopulations of patients who have increased sensitivity to the
berzosertib (M6620, VX-970)/carboplatin/gemcitabine/pembrolizumab combination.
II. To explore the prognostic and predictive qualities of the ATM immunohistochemistry (IHC)
assay for clinical response and PFS.
III. To explore inflammation-associated gene signatures and clinical response.
OUTLINE: This is a phase Ib, dose de-escalation study of carboplatin followed by a phase II
study. Patients are randomized to 1 of 2 arms.
ARM A: Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1,
gemcitabine hydrochloride IV over 30 minutes on days 1 and 8, carboplatin IV over 30 minutes
on day 1, and berzosertib IV over 60 minutes on days 2 and 9. Treatment repeats every 21 days
for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients
then receive pembrolizumab IV over 30 minutes on day 1 and berzosertib IV over 60 minutes on
days 2 and 9. Cycles repeat every 21 days for up to 9 months in the absence of disease
progression or unacceptable toxicity. Patients then receive pembrolizumab alone IV over 30
minutes on day 1. Cycles repeat every 6 weeks for up to 1 more year in the absence of disease
progression or unacceptable toxicity. Patients undergo magnetic resonance imaging (MRI) scans
and/or computed tomography (CT) scans, and undergo blood specimen collection on study.
ARM B: Patients receive pembrolizumab, gemcitabine hydrochloride, and carboplatin as in Arm
A. Patients undergo MRI scans and/or CT scans, and undergo blood specimen collection on
study.
After completion of study treatment, patients are followed up every 3 months for 12 months.

- Patients must be willing to comply with birth control requirements: The effects of the agents in this study (or similar agents) on the developing human fetus are either unknown, or known to be teratogenic, embryotoxic, and fetotoxic in mice and rabbits. For this reason, 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, and for 6 months after completing treatment administration. 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.

- Patients with severe bone marrow depression or significant bleeding are not eligible
- Patients with psychiatric illness/social situations that would limit compliance with study requirements are not eligible
- Berzosertib (M6620, VX-970) is primarily metabolized by CYP3A4; therefore, concomitant administration with strong inhibitors of CYP3A4 (e.g. clarithromycin, itraconazole, ketoconazole, HCV and HIV protease inhibitors, nefazodone, posaconazole, telithromycin, voriconazole) or strong inducers of CYP3A4 (e.g. carbamazepine, rifampin, phenobarbital, phenytoin, St. John's wort) should be avoided. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
- Pregnant women are excluded from this study because the agents in this study may have the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with the study agents, breastfeeding should be discontinued if the mother is treated with the study agents berzosertib (M6620, VX-970), pembrolizumab, gemcitabine, or carboplatin
- Berzosertib (M6620, VX-970) should be used with caution in patients with clinical evidence of germline defects in their deoxyribonucleic acid (DNA) damage repair pathway (for example, patients with Li-Fraumeni syndrome or ataxia telangiectasia) due to a possible increase in the toxicity of DNA-damaging agents when paired with berzosertib (M6620, VX-970)
- Patients must not have received or be scheduled to receive radiation therapy within 7 days or less from gemcitabine administration
