Objectives
The primary objective of this study is to determine the **progression-free survival rate (PFSR)** at 3 months in patients with advanced Angiosarcoma and Undifferentiated Pleomorphic Sarcoma, utilizing the Response Evaluation Criteria in Solid Tumors (RECIST v1.1). This is clinically relevant as it provides an early indicator of the treatment's efficacy in halting disease progression, which is crucial for assessing the potential benefit of the therapeutic regimen.
Secondary objectives include:
- Determining the **objective response rate (ORR)** and duration of response (DOR) using RECIST v1.1, which helps in evaluating the proportion of patients who experience a predefined amount of tumor size reduction and the duration of this response.
- Assessing **progression-free survival (PFS)** and **overall survival (OS)**, which are critical endpoints for understanding the long-term benefits of the treatment.
- Evaluating the **safety and tolerability** of the combination of pembrolizumab and propranolol, ensuring that the treatment is not only effective but also safe for patients.
- Determining the **quality of life (QoL)** of patients, which is essential for understanding the impact of the treatment on patients' daily living and well-being.
- Exploring the association between anti-tumor activity and specific **biomarker measures** in tumor tissue and peripheral blood, which may provide insights into the mechanisms of action and potential predictive markers of response.
Participants
The clinical trial involves participants diagnosed with **Advanced Angiosarcoma** and **Undifferentiated Pleomorphic Sarcoma**. The study population includes both male and female subjects aged 18 years and older. Participants are required to have a histologically confirmed diagnosis of unresectable locally advanced or metastatic forms of the disease, having shown progression or lack of clinical benefit from first-line standard chemotherapy. The trial population was selected based on specific inclusion criteria, including an Eastern Cooperative Oncology Group Performance Status (ECOG PS) score of 2 or less, and the ability to comply with study requirements. Participants must have evaluable disease as defined by the Response Evaluation Criteria in Solid Tumors (RECIST version 1.1). The trial also considers vulnerable populations. However, the sponsor has not provided information regarding the total number of participants. Lifestyle considerations such as diet and physical activity are not specified in the available data.
Plans and Procedures
The clinical trial is designed to evaluate the efficacy of **propranolol hydrochloride** in combination with **pembrolizumab** for the treatment of advanced **angiosarcoma** and **undifferentiated pleomorphic sarcoma**. This is a phase II, open-label study with a primary objective to determine the progression-free survival rate at three months, assessed by the Response Evaluation Criteria in Solid Tumors (RECIST v1.1). The trial employs a randomized, controlled design to ensure the reliability of the results. The estimated duration of the trial is from December 2022 to December 2028, with a maximum treatment period of 104 weeks for each participant.
Participants will undergo a series of study visits, beginning with an inclusion (screening) visit to confirm eligibility based on specific criteria, such as age, performance status, and laboratory values. Following the screening, eligible participants will be enrolled and receive treatment according to the study protocol. Regular follow-up visits will be scheduled to monitor the participants' response to treatment, assess any adverse events, and ensure compliance with the study requirements. The end-of-study visit will occur at the conclusion of the treatment period or upon early termination, where final assessments will be conducted.
The expected length of participant involvement is up to 104 weeks, depending on individual response and tolerance to the treatment. Conditions that may lead to early termination from the study include significant adverse events, disease progression, or withdrawal of consent by the participant. The study will adhere to ethical guidelines, ensuring that all participants provide informed consent and are aware of their rights throughout the trial. The trial's endpoints include the percentage of patients achieving complete response, partial response, or stable disease at three months, as well as secondary endpoints such as median progression-free survival, overall survival, and quality of life assessments.
Treatment
The clinical trial involves the administration of **PROPRANOLOL HYDROCHLORIDE**, a beta-blocker, in the form of film-coated tablets. The active substance, propranolol hydrochloride, is of chemical origin. The maximum daily dose is 80 mg, with a total maximum dose of 58,240 mg over a treatment period of up to 104 weeks. The medication is administered orally. Participant compliance with the dosing schedule will be monitored throughout the study to ensure adherence to the prescribed regimen.
**KEYTRUDA** (pembrolizumab) is also utilized in this trial. It is provided as a 25 mg/mL concentrate for solution for infusion. Pembrolizumab is a protein-based therapeutic agent, specifically classified under the ATC code L01FF02. The maximum daily dose is 2 mg/kg, with a total maximum dose of 68 mg/kg over the same treatment period of 104 weeks. The administration route is intravenous, and the infusion schedule will be closely monitored to ensure proper dosing and participant compliance.
No non-experimental treatments, such as standard-of-care therapy, placebo, or comparator treatments, are specified in this study. The trial aims to evaluate the efficacy of the experimental medications in achieving the main objective, which is to determine the progression-free survival rate at 3 months using the Response Evaluation Criteria in Solid Tumors (RECIST v1.1).
Efficacy
Efficacy in the clinical trial will be assessed using several key endpoints. The primary endpoint is the percentage of patients alive with complete response (CR), partial response (PR), and stable disease (SD) according to the Response Evaluation Criteria in Solid Tumors (RECIST v1.1) at 3 months. Secondary endpoints include the percentage of patients with CR and PR, including the duration of these responses using RECIST v1.1, median progression-free survival (PFS) and overall survival (OS), adverse events as per the Common Terminology Criteria for Adverse Events (CTCAE) v5.0, and patient-reported outcomes using the 30-item European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ C30).
The main objective of the trial is to determine the progression-free survival rate (PFSR) at 3 months, evaluated by RECIST v1.1. Efficacy assessments will be conducted at specified intervals throughout the trial, with the primary endpoint being evaluated at the 3-month mark. The trial will utilize validated scales and criteria, such as RECIST v1.1 and CTCAE v5.0, to ensure consistent and reliable measurement of efficacy parameters. The trial is designed to provide comprehensive data on the efficacy of the treatment regimen in patients with advanced **Angiosarcoma** and Undifferentiated Pleomorphic Sarcoma.
