M7824 and Topotecan or Temozolomide in Relapsed Small Cell Lung Cancers

Safety Run-In and Phase II Trial of M7824 and Topotecan or Temozolomide in Relapsed Small Cell Cancers

BACKGROUND:

• Small cell lung cancer (SCLC) is an aggressive cancer with a poor prognosis. Although highly responsive to chemotherapy initially, SCLC relapses quickly and becomes refractory to treatment within a few months.
• The inability to destroy residual SCLC cells despite initial chemosensitivity suggests the existence of a highly effective deoxyribonucleic acid (DNA) damage response network. SCLC is also characterized by high DNA replication stress (retinoblastoma (RB1) inactivation, MYC and CCNE1 activation).
• There is only one Food and Drug Administration (FDA) approved treatment for patients with relapsed SCLC after first-line chemotherapy: topotecan, which inhibits religation of topoisomerase I-mediated single-strand DNA breaks leading to lethal double-strand DNA breaks. Temozolomide, an oral alkylating agent, which causes DNA damage by alkylating guanine at position O6 also has activity in relapsed SCLC, particularly for brain metastases.
• Preliminary evidence indicates that disruption of the immune checkpoint programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) pathway can yield responses in a subset of SCLC patients, but response rates (approximately equal to 10%) are lower than non-small cell lung cancer (NSCLC) and other tumors with comparable tumor mutational burden indicating additional immunosuppressive mechanisms at play in the SCLC tumor microenvironment.
• M7824 (MSB0011359C) is a bifunctional fusion protein consisting of an anti-programmed death ligand 1 (PDL1) antibody and the extracellular domain of transforming growth factor beta (TGF-beta) receptor type 2, a TGF-beta trap.
• Safety data from the dose-escalation study in solid tumors as well as preliminary data from expansion cohorts show that M7824 has a safety profile similar to other checkpoint inhibiting compounds.
• Combining immunotherapy, and chemotherapy could synergistically improve the anticancer activity of immunotherapy. Combination of chemotherapy with immunotherapy have improved outcomes in NSCLC and melanoma leading to Food and Drug Administration (FDA) approvals of such combinations.
• We hypothesize that increased DNA damage induced by topotecan and temozolomide will complement the anti-tumor activity of M7824, in recurrent SCLC.

OBJECTIVE:

- The primary objective of the trial is to determine the efficacy (using objective response rate) of M7824 plus topotecan or temozolomide in relapsed SCLC.

ELIGIBILITY:

• Subjects with histological or cytological confirmation of SCLC.
• Subjects must be greater than or equal to 18 years of age and have a performance status (Eastern Cooperative Oncology Group (ECOG) less than or equal to 2.
• Subjects must not have received chemotherapy or undergone major surgery within 2 weeks and radiotherapy within 24 hours prior to enrollment.
• Subjects must have adequate organ function and measurable disease.

DESIGN:

• Arm A (M7824 monotherapy): Up to 10 patients may be treated with M7824 monotherapy to obtain safety and pharmacokinetic (PK) data, and a preliminary estimate of clinical responses to M7824 in SCLC. Patients with progressive disease on Arm A may then receive M7824 plus temozolomide as per description of treatment for Arm C.
• Arm B (M7824 plus topotecan) and Arm C (M7824 plus temozolomide) will be administered in 3 and 4-week cycles respectively; these arms will have a safety run-in followed by efficacy analysis. Up to 10 patients with extrapulmonary small cell cancer will be enrolled in arm C to receive the combination of M7824 and temozolomide.
• Optional tumor biopsies will be obtained at pre-treatment on cycle 1 day 1 (C1D1) and C1D15 for Arm C; pre-treatment on C1D1 and cycle 2 day 1 (C2D1) for arms A and B.
• Every subject of each arm of the safety run-in will be observed for at least 7 days after first dose of M7824 before the subsequent subject can be treated. Subjects who are not evaluable for dose-limiting toxicity (DLT) will be replaced and not included into evaluation.

ARMS:

• Arm A (3-week cycles): M7824 monotherapy 2400 mg every 3 weeks until disease progression or a criterion in Protocol is met. Patients with progressive disease on Arm A may then receive 1200 mg M7824 every 2 weeks plus temozolomide 200 mg/m^2/day on days 1-5 every 4 weeks.
• Arm B (3-week cycles): M7824 2400 mg plus topotecan 1 mg/m(2) on days 1-5 every 3 weeks until disease progression or a criterion in Protocol is met.
• Arm C (4-week cycles): M7824 1200 mg every 2 weeks plus temozolomide 200 mg/m(2)/day on days 1-5 every 4 weeks until disease progression or a criterion in Protocol is met.

Detailed Description

Background

Small cell lung cancer (SCLC) is an aggressive cancer with a poor prognosis. Although highly responsive to chemotherapy initially, SCLC relapses quickly and becomes refractory to treatment within a few months.

Extrapulmonary small cell cancers are extremely rare and management of systemic disease with chemotherapy is patterned after the approach used in SCLC.

The inability to destroy residual SCLC cells despite initial chemosensitivity suggests the existence of a highly effective deoxyribonucleic acid (DNA) damage response network. SCLC is also characterized by high DNA replication stress (retinoblastoma (RB1) inactivation, MYC and CCNE1 activation). Similarly, extrapulmonary small cell cancers have no standard treatments and it appears that although these cancers can arise by different mechanisms, they have in common high replication stress, that may be susceptible to DNA damage and immune checkpoint blockade.

There is only one Food and Drug Administration (FDA) approved treatment for patients with relapsed SCLC after first-line chemotherapy: topotecan, which inhibits religation of topoisomerase I-mediated single-strand DNA breaks leading to lethal double-strand DNA breaks. Temozolomide, an oral alkylating agent, which causes DNA damage by alkylating guanine at position O6 also has activity in relapsed SCLC, particularly for brain metastases.

Preliminary evidence indicates that disruption of the immune checkpoint programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) pathway can yield responses in a subset of SCLC patients, but response rates (approximately 10%) are lower than NSCLC and other tumors with comparable tumor mutational burden indicating additional immunosuppressive mechanisms at play in the SCLC tumor microenvironment.

M7824 (MSB0011359C) is a bifunctional fusion protein consisting of an anti-programmed death ligand 1 (PD-L1) antibody and the extracellular domain of transforming growth factor beta (TGF- beta) receptor type 2, a TGF- beta trap.

Safety data from the dose-escalation study in solid tumors as well as preliminary data from expansion cohorts show that M7824 has a safety profile similar to other checkpoint inhibiting compounds.

Combining immunotherapy, and chemotherapy could synergistically improve the anticancer activity of immunotherapy. Combination of chemotherapy with immunotherapy have improved outcomes in non-small cell lung cancer (NSCLC) and melanoma leading to FDA approvals of such combinations.

We hypothesize that increased DNA damage induced by topotecan and temozolomide will complement the anti-tumor activity of M7824, in recurrent SCLC.

Objective

The primary objective of the trial is to determine the efficacy (using objective response rate) of M7824 plus topotecan or temozolomide in relapsed SCLC.

Eligibility

Subjects must be greater than or equal to 18 years of age and have a performance status Eastern Cooperative Oncology Group (ECOG) less than or equal to 2.

Subjects must not have received chemotherapy or undergone major surgery within 2 weeks and radiotherapy within 24 hours prior to enrollment.

Subjects must have adequate organ function and measurable disease.

Design

Arm A (M7824 monotherapy): Up to 10 patients may be treated with M7824 monotherapy to obtain safety and PK data, and a preliminary estimate of clinical responses to M7824 in SCLC. Patients with progressive disease on Arm A may then receive M7824 plus temozolomide as per description of treatment for Arm C.

Arm B (M7824 plus topotecan) and Arm C (M7824 plus temozolomide) will be administered in 3 and 4-week cycles respectively; these arms will have a safety run-in followed by efficacy analysis. Up to 10 patients with extrapulmonary small cell cancer will be enrolled in arm C to receive the combination of M7824 and temozolomide.

Optional tumor biopsies will be obtained at pre-treatment on cycle 1 day 1 (C1D1) and C1D15 for Arm C; pre-treatment on C1D1 and cycle 2 day 1 (C2D1) for arms A and B.

Every subject of each arm of the safety run-in will be observed for at least 7 days after first dose of M7824 before the subsequent subject can be treated. Subjects who are not evaluable for dose-limiting toxicity (DLT) will be replaced and not included into evaluation.

• Ability of subject to understand and the willingness to sign a written informed consent document.
• The effects of the trial treatment on the developing human fetus are unknown; thus, women of childbearing potential and men must agree to use highly-effective contraception prior to study entry, for the duration of study participation and up to 6 months for women and 3 months for men after the last dose of study drug. Men should not donate sperm during participation in the study and for up to 3 months after the last dose of study drug. 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.

EXCLUSION CRITERIA:

• Subjects with tumor amenable to potentially curative therapy per principal investigator (PI).
• Subjects who are receiving any other investigational agents. Prior immunotherapy, topotecan and temozolomide are allowed.
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to (study agent) or other agents used in study.
• Subjects with symptomatic brain metastases will be excluded from trial secondary to poor prognosis. However, subjects who have asymptomatic brain metastases, and those had treatment for their brain metastasis and whose brain disease is stable without steroid therapy for 2 weeks may be enrolled (replacement doses less than or equal to 10 mg of prednisone or equivalent per day are allowed).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Proportion of Evaluable Participants Who Experience a Partial Response (PR) or Complete Response (CR) Reported Along With an 80% Confidence Interval.	The fraction of evaluable participants who experience a PR or CR will be determined and this fraction will be reported along with an 80% confidence interval. Response was measured by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. Partial response is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters. Complete response is disappearance of all target lesions and any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm.	6 weeks (Arm B) or 8 weeks (Arm C)
Proportion of Evaluable Participants Who Experience a Partial Response (PR) or Complete Response (CR) Reported Along With an 95% Confidence Interval.	The fraction of evaluable participants who experience a PR or CR will be determined and this fraction will be reported along with an 95% confidence interval. Response was measured by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. Partial response is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters. Complete response is disappearance of all target lesions and any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm.	6 weeks (Arm B) or 8 weeks (Arm C)
Number of Participants Experiencing a Dose-limiting Toxicity (DLT) by Grade and Type	Fraction of participants experiencing a dose-limiting toxicity (DLT) by grade and type assessed by the CTCAE. Grade 3 is severe. Grade 4 is life threatening. Grade 5 is death related to adverse event. The occurrence of any of the following toxicities will be considered a DLT if judged by the Investigator to be possibly, probably or definitely related to study drug administration: Grade 4 non-hematologic toxicity (not laboratory). Grade 4 hematologic toxicity lasting ≥7 days. Grade 3 non-hematologic toxicity (not laboratory, specifically nausea, vomiting and diarrhea) lasting >5 days despite optimal supportive care. Febrile neutropenia Grade 3 or Grade 4. Thrombocytopenia <25,000/mm3 if associated with a bleeding event which does not result in hemodynamic instability but requires an elective platelet transfusion, or a life-threatening bleeding event which results in urgent intervention.	3 weeks for Arm A; First cycle (Arm B - 3 weeks and Arm C- 4 weeks)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Proportion of Grade 3 and/or Grade 4 Adverse Events	Safety of the agent will be assessed by determining the grade of adverse events noted in each participant and reporting the fraction with grade 3 and/or grade 4 adverse events. Adverse events were assessed by the Common Terminology Criteria for Adverse Events (CTCAE) v5.0. Grade 3 is severe. Grade 4 is life-threatening.	Document adverse events from the first study intervention through 30 days after the participant received the last study treatment administration, approximately 30-353 days
Progression Free Survival (PFS)	PFS is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first. PFS will begin at the on-study date and will consider progressions as well as death without progression as an event. Progression was measured by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 and is at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study. The appearance of one or more new lesions is also considered progressions. PFS was measured using the Kaplan-Meier method and is reported along with a 95% confidence interval.	At 6 months
Duration of Response (DOR)	Duration of overall response is measured from the time measurement criteria are met for complete response (CR) or partial response (PR) (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented using the Kaplan-Meier method and reported along with a 95% confidence interval. Response is measured by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. Complete response is disappearance of all target lesions and any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Partial response is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters. Progression is at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study. The appearance of one or more new lesions is also considered progressions.	At 6 months
Overall Survival (OS)	OS is defined as the date of on-study to the date of death from any cause or last follow up. OS was measured using the Kaplan-Meier method and is reported along with a 95% confidence interval.	maximum of 67.14 months
