Clinical Trial Summary

The purpose of this study was to determine an effective and safe dose of sotatercept (ACE-011) for the treatment of chemotherapy-induced anemia (CIA) in participants with metastatic non-small cell lung cancer (NSCLC) who are being treated with first-line platinum based chemotherapy.

Description:

The ACE-011-NSCL-001 Phase 2a study was an open-label, randomized, dose-ranging study designed to assess the efficacy, safety, tolerability, pharmacokinetic and quality of life of sotatercept for treatment of CIA in participants with advanced or metastatic solid tumors treated with platinum-based chemotherapeutic regimens. Other objectives included the effect of sotatercept treatment on bone metabolism, the evaluation of the expression of Activin A and other proteins/biomarkers (including myostatin and follistatin) and the assessment of renal function biomarkers. The study consisted of a Screening Period, a Treatment Period of approximately 6 months (up to 4 doses of sotatercept at either 15 mg or 30 mg administered subcutaneously every 42 days) and a Post-treatment Follow-up Period or End of Treatment (42 days after the last dose of sotatercept). The study was terminated early due to a slower than expected rate of enrollment as a result of substantial changes in the standard of care for cancer participants with anemia which resulted in challenges to timely accrual and completion of the study. Therefore, 26 participants were randomized into the study and the planned Part 2 of the study consisting of a double-blind, randomized, placebo-controlled Phase 2b/3 study conducted at the optimal dose of sotatercept in up to 750 participants with metastatic NSCLC was not performed. Due to the small sample size and variability of the data, changes were made to modify the study endpoints and revise them to be exploratory only.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants Who Experienced a Hematopoietic Response	A hematopoietic response was defined as an increase in a participant's hemoglobin (Hgb) of =1.0 g/dL above the study baseline value for 4 consecutive weeks, in the absence of red blood cell transfusion and/or erythropoiesis-stimulating agents.	Up to Day 28
Secondary	Number of Participants Who Experienced One or More Adverse Events (AEs)	An AE is any untoward medical occurrence in a study participant administered a pharmaceutical product that does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not related to the medicinal product.	Up to approximately 6 months
Secondary	Time to Progression (TTP)	TTP was defined as the time from date of randomization to date of diagnosis of progressive disease	Up to 6 months
Secondary	Progression Free Survival (PFS)	PFS was defined as the time from the start of study drug therapy to the first observation of disease progression or death due to any cause, whichever came first	Up to 12 months
Secondary	Overall Survival (OS)	OS was defined as the time between randomization and death	Up to 24 months
Secondary	Overall Response Rate (ORR)	Overall Response was defined as the percentage of participants who achieved an objective confirmed complete (CR) or partial response (PR). Response was determined according to Response Evaluation Criteria in Solid Tumors (RECIST) v 1.1 guidelines. CR: The disappearance of all known disease and no new sites or disease-related symptoms confirmed at least 4 weeks after initial documentation. All sites must be assessed, including non-measurable sites, such as effusions, or markers. PR: At least a 30% decrease in the sum of the longest diameters of target lesions, taking as a reference the baseline sum of the longest diameters confirmed at least 4 weeks after initial documentation and no new non-target lesions and/or unequivocal progression of existing non-target lesions. PR is also recorded when all measurable disease has completely disappeared, but a non-measurable component (i.e., ascites) is still present but not progressing.	Up to 12 months
Secondary	Number of Participants Who Experienced an Improvement in Quality of Life Scores	Participants were to be assessed on improvement of quality of life using the Functional Assessment of Chronic Illness Therapy (FACIT) Fatigue Scale (Version 4.0) and the Lung Cancer Symptom Scale (LCSS). The FACIT Fatigue score ranges from 0 to 52, with 0 representing the best outcome and 52 representing the worst outcome. The LCSS is a 9-item patient-rated scale, 6 of which measure major symptoms (loss of appetite, fatigue, cough, dyspnoea, pain, and haemoptysis), and 3 of which are summation items related to total symptomatic distress, activity, and overall quality of life. Participants responses are measured using the mean score on the 9-item visual analogue scales, with 100-mm lines, with 0 representing the best outcome and 100 representing the worst outcome.	Up to 6 months
Secondary	Area Under the Concentration Versus Time Curve From Time 0 to 28 Days (AUC0-28d) of Sotatercept Following a Single Dose	AUC0-28d is a measure of the mean concentration levels of a drug in the plasma from time 0 to 28 days.	Pre-dose 1 Day 1, 4 hours post-dose Day 1, Day 5, Day 8, Day 11, Day 15, Day 22, Day 28
Secondary	Area Under the Concentration Versus Time Curve From Time 0 to Infinity (AUC0-inf) of Sotatercept Following a Single Dose	AUC0-inf is the area under the plasma concentration versus time curve from time zero (pre-dose) to extrapolated infinite time.	Pre-dose 1 Day 1, 4 hours post-dose Day 1, Day 5, Day 8, Day 11, Day 15, Day 22, Day 29, Day 36, pre-dose 2 Day 43
Secondary	Maximum Plasma Concentration (Cmax) of Sotatercept Following a Single Dose	Cmax is a measure of the maximum amount of drug in the plasma after a dose is given.	Pre-dose 1 Day 1, 4 hours post-dose Day 1, Day 5, Day 8, Day 11, Day 15, Day 22, Day 29, Day 36, pre-dose 2 Day 43
Secondary	Time to Maximum Concetration (Tmax) of Sotatercept Following a Single Dose	Tmax is a measure of the time it takes for a drug to reach maximum concentration in the plasma after the dose is given.	Pre-dose 1 Day 1, 4 hours post-dose Day 1, Day 5, Day 8, Day 11, Day 15, Day 22, Day 29, Day 36, pre-dose 2 Day 43
Secondary	Apparent Terminal Half-life (t1/2) of Sotatercept Following a Single Dose	t1/2 is the elimination half-life of study drug: the time it takes for half of the study drug in the blood plasma to dissipate.	Pre-dose 1 Day 1, 4 hours post-dose Day 1, Day 5, Day 8, Day 11, Day 15, Day 22, Day 29, Day 36, pre-dose 2 Day 43
Secondary	Apparent Serum Clearance (CL/F) of Sotatercept Following a Single Dose	Apparent serum CL is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes.	Pre-dose 1 Day 1, 4 hours post-dose Day 1, Day 5, Day 8, Day 11, Day 15, Day 22, Day 29, Day 36, pre-dose 2 Day 43
Secondary	Apparent Volume of Distribution (Vz/F) Following a Single Dose of Sotatercept	Vz/F is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug.	Pre-dose 1 Day 1, 4 hours post-dose Day 1, Day 5, Day 8, Day 11, Day 15, Day 22, Day 29, Day 36, pre-dose 2 Day 43
