Trial Summary

What is the purpose of this trial?

This is a multicenter, randomized, open label phase lll trial to assess whether preoperative chemotherapy, as an adjunct to curative-intent surgery, improves the prognosis of high risk DDLPS (dedifferentiated Liposarcoma) and LMS (Leiomyosarcoma) patients as measured by disease free survival. After confirmation of eligibility criteria, patients will be randomized to either the standard arm or experimental arm.

Do I need to stop my current medications for this trial?

The trial protocol does not specify if you need to stop taking your current medications. However, if you have uncontrolled high blood pressure, you may need to adjust your antihypertensive medication before joining the study. It's best to discuss your current medications with the trial team.

What data supports the idea that Preoperative Chemotherapy + Surgery for Sarcoma is an effective treatment?

The available research shows that using preoperative chemotherapy before surgery for sarcoma can lead to better outcomes. For example, in osteosarcoma, this approach has resulted in a 93% disease-free survival rate over a median of 20 months. This means that most patients did not show signs of the disease during this period. Additionally, preoperative chemotherapy can make surgery less invasive, allowing for limb-sparing procedures instead of more drastic surgeries. This treatment strategy also helps identify patients who might need different therapies if the initial chemotherapy isn't effective, improving overall treatment results.12345

What safety data exists for preoperative chemotherapy and surgery for sarcoma?

The safety data for preoperative chemotherapy and surgery for sarcoma is limited and varies. Real-world data suggests that perioperative chemotherapy is used in high-risk, localized soft tissue sarcoma, but potential toxicity from cytotoxic chemotherapy is substantial. There is little consensus on the indications for chemotherapy in the adjuvant/neoadjuvant setting. Some studies have evaluated toxicity and survival outcomes, but the efficacy and safety remain controversial, with few prospective studies available. Adjuvant chemotherapy is standard for certain sarcoma subtypes, but not for low- and intermediate-risk disease, and the benefits for high-risk disease are not convincingly demonstrated.678910

Is surgery a promising treatment for sarcoma?

Yes, surgery is a promising treatment for sarcoma, especially when combined with preoperative chemotherapy. This approach can make surgeries easier and safer, potentially allowing for less invasive procedures and better outcomes.17111213

Eligibility Criteria

This trial is for adults with high-risk leiomyosarcoma or liposarcoma in the retroperitoneal or pelvic spaces, who haven't had previous treatments. Tumors must be a certain size and meet specific criteria. Patients need to have good organ function, no severe illnesses, not be pregnant or breastfeeding, and agree to use effective birth control.

Inclusion Criteria

My diagnosis was confirmed with specific tests for MDM2 and CDK4.
I have a specific type of sarcoma (DDLPS) that is considered high risk but operable.
Criteria for non-resectability are: Involvement of the superior mesenteric artery, aorta, coeliac trunk and/or portal vein. Involvement of bone. Growth into the spinal canal. Progression of retro-hepatic inferior vena cava leiomyosarcoma towards the right atrium. Infiltration of multiple major organs like liver, pancreas and/or major vessels. Tumor not previously treated (no previous surgery (excluding diagnostic biopsy), radiotherapy or systemic therapy). Patient must have radiologically measurable disease (RECIST 1.1), as confirmed by imaging within the 28 days prior to randomization. CT thorax abdomen pelvis with IV contrast is the preferred imaging modality. In case of any contra-indications (medical or regulatory), it is allowed to perform a non-contrast CT thorax + MRI abdomen & pelvis. ≥ 18 years old (no upper age limit). WHO (World Health Organization) performance status ≤ 2. Adequate haematological and organ function: Haematological: haemoglobin > 9.0 g/dL or 5.6 mmol/L, absolute neutrophils > 1.5 x 109/L, platelets > 100 x 109/L Note: Platelet transfusions is allowed to achieve these baseline values. Renal: estimated glomerular filtration rate (eGFR) > 50 ml/min/m2; No proteinuria CTCAE ≥ grade 2. Hepatic: Bilirubin ≤ 1.0 times upper limit of normal (1.0xULN) of institutional limits, ALT (alanine aminotransferase) and/or AST (aspartate transaminase) ≤1.5 x ULN. If isolated elevated bilirubin <2 x ULN and Gilberts syndrome suspected, suggest repeating bloods after food. If bilirubin improves to meet the criteria above this is acceptable. More severe persistent hepatic impairment of whatever cause would exclude the patient from treatment till resolved. Heart: Clinically normal cardiac function based on left ventricular ejection fraction (LVEF ≥ 50%) as assessed either by multi-gated acquisition scan (MUGA) or cardiac ultrasound and 12 lead ECG without clinically relevant abnormalities. American Society of Anesthesiologist (ASA) score < 3. Women of child bearing potential (WOCBP) must have a negative serum pregnancy test within 7 days prior to the first dose of study treatment or surgery. Note: a woman is considered of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming post menopausal unless permanently sterile. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. However in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient. Patients of childbearing / reproductive potential should use highly effective birth control measures, as defined by the investigator, during the study treatment period and for at least 6 months after the last dose of treatment or date of surgery. A highly effective method of birth control is defined as a method which results in a low failure rate (i.e. less than 1% per year) when used consistently and correctly. Such methods include: Combined (oestrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal). Progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable). Intrauterine device (IUD). Intrauterine hormone-releasing system (IUS). Bilateral tubal occlusion. Vasectomized partner. Sexual abstinence (the reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient). Female subjects who are breast feeding should discontinue nursing prior to the first day of study treatment and until 6 months after the last study treatment. Before patient registration/randomization, written informed consent must be given according to ICH/GCP, and national/local regulations.

Findings from Research

Preoperative chemotherapy for soft tissue sarcoma can help determine the effectiveness of treatment, potentially allowing for less invasive surgical options and reducing major surgical complications.
The approach to using chemotherapy, surgery, and radiation therapy must be tailored to each patient based on tumor stage and grade, ensuring optimal tumor control while minimizing side effects.
Preoperative chemotherapy in soft tissue sarcoma.Lokich, JJ.[2013]
Primary systemic chemotherapy followed by delayed surgery has shown better outcomes for osteogenic sarcomas compared to immediate surgery, allowing for limb preservation and reducing the time lost to postoperative therapy.
At Memorial Sloan Kettering Cancer Center, patients who did not respond favorably to preoperative chemotherapy were switched to alternative regimens, resulting in a 93% disease-free survival rate over a median of 20 months, suggesting that this tailored approach could be beneficial for treating other aggressive tumors.
[New therapeutic results in osteosarcoma].Urban, C., Rosen, G.[2022]
In a study of 81 sarcoma patients who underwent pulmonary metastasectomy after chemotherapy, measurable progression of lung metastases post-chemotherapy was identified as a significant predictor of poor survival outcomes, with a hazard ratio of 4.025.
Patients who experienced progression after chemotherapy had a five-year survival rate of 0%, compared to 32% for those without progression, highlighting the critical impact of post-chemotherapy disease status on prognosis.
Progression after chemotherapy is a novel predictor of poor outcomes after pulmonary metastasectomy in sarcoma patients.Stephens, EH., Blackmon, SH., Correa, AM., et al.[2022]
