MiRaDor Trial marks first-ever joint effort by MEDSIR and Oncoclinicas & Co in pioneering breast cancer research

  • The MiRaDor trial, a proof-of-concept study, aims to evaluate the usefulness of ctDNA analysis to detect Minimal Residual Disease in early breast cancer patients who are at high risk of relapse



  • This marks the first-time MEDSIR and Oncoclínicas will join forces to perform a trial together, with MEDSIR taking the lead in launching the advanced platform for patient monitoring and Oncoclínicas & Co contributing from multiple recruiting centers



  • In 2022, MEDSIR and Oncoclínicas forged a strategic partnership, uniting their efforts to advance independent clinical research throughout Latin America and drive global independent oncological investigations

SAN ANTONIO, Dec. 6, 2023 /PRNewswire/ -- MEDSIR presented today the design of the MiRaDor trial, a proof-of-concept study, conducted in collaboration with  Oncoclínicas & Co, which aims to evaluate the usefulness of ctDNA analysis to detect minimal residual disease in patients who had hormone receptor positive/HER2 negative early breast cancer and are at high risk of relapse.  The study will evaluate if serial blood sample analysis (with a periodicity of 3 months during the first year, and every 6 months afterwards) is able to identify early if cancer has returned, even before this can be detected by commonly used imaging tests. Additionally, it will evaluate if serial blood sample analysis can early identify if the patients are responding to a specific breast cancer treatment. The study will also assess patients with 90% decreases in baseline ctDNA at 6, 9, and 12 months, along with those with 70% and 50% decreases at corresponding intervals. 

This momentous partnership marks the first time these two entities will work together to recruit patients and conduct a trial, with MEDSIR being responsible for launching the advanced platform for patient monitoring and active participation from Oncoclínicas & Co across multiple recruiting centers. The genesis of this collaboration can be traced back to 2022 when MEDSIR — a global company specializing in the strategic design of independent clinical research — and Oncoclínicas & Co — considered one of the largest and most respected groups in oncology, hematology, and radiotherapy in Latin America — forged a strategic partnership, pooling their efforts to propel independent clinical research across Latin America and spearhead global investigations in oncology. 

The absence of an accurate test to determine relapse risks with standard-of-care treatment highlights the critical need for methods capable of swift identification and prediction of recurrence risk, as well as assessing treatment effectiveness in a more expedited manner. In response to this imperative, the innovative companies united forces for the first-time to launch this platform for enhanced patient monitoring, which will commence in December 2023 until June 2028.

This pioneer platform systematically assesses how circulating tumor DNA (ctDNA) changes over time and in response to treatment, serving as a valuable tool in determining patients who are likely to experience disease recurrence. Moreover, it holds the potential to contribute significantly to the analysis of the efficacy of escalating new therapies for patients undergoing a relapse.

Recent advancements in liquid biopsy methods, specifically circulating tumor DNA (ctDNA) analysis, have created a non-invasive alternative to traditional biopsies. ctDNA, small tumor DNA fragments present in the bloodstream, allows for the detection of minimal residual disease (MRD), often undetectable by standard tests. The MiRaDor trial integrates these innovative liquid biopsy methods into its two-phase structure: surveillance and treatment.

The surveillance phase will involve 1,260 patients with HR[+]/HER2­ early breast cancer undergoing endocrine therapy. Blood samples will be collected and ctDNA will be analyzed at multiple intervals to monitor changes over time. Patients with positive ctDNA results, without evidence of progression by imaging, will move to the treatment phase. In this subsequent phase, 40-60 patients will be assigned to one of four arms: (A) standard endocrine therapy (control group); (B) giredestrant (a selective estrogen degrader); (C) giredestrant + abemaciclib (a cyclin-dependent kinase 4/6 inhibitor); or (D) giredestrant + inavolisib (for patients with a PIK3CA mutation). Treatment and ctDNA assessments will continue until evidence of disease progression, physician's or patient's decision, or study completion.

The MiRaDor clinical trial embodies a pivotal step towards advancing breast cancer patient care. Beyond its primary goal of early detection through the correlation of ctDNA changes with treatment efficacy, the study envisions itself as a transformative platform for heightened patient monitoring. This strategic approach not only facilitates the timely identification of patient progression but also enables swift therapeutic interventions, ultimately contributing to individualized and enhanced patient outcomes.

Lastly, the significance of MiRaDor lies not only in its cutting-edge technology and strong strategic and scientific foundation but also in its role as the inaugural collaboration between MEDSIR and Oncoclínicas & Co in patient recruitment and trial execution. This milestone underscores MEDSIR's commitment to developing innovative clinical trials that have the potential to revolutionize the management of breast cancer patients, offering new ways for improved care and treatment strategies.
