Onderzoek naar de optimalisering van de behandeling van Gastro-Intestinale Stroma tumoren (GIST) door het monitoren van mutaties in circulerend tumor DNA (ctDNA): GALLOP-11 studie

Acronym

GALLOP-11

Reference code

NCT05178030

Intervention model

Prospective observational cohort study

Full description

This is an observational, non-interventional, multicenter study. The study will be performed within the Dutch GIST consortium (NKI-AvL, Erasmus MC, Radboud UMC, LUMC and UMCG). Patients diagnosed with GIST with a KIT exon 11 mutations that can be detected by our ddPCR assay are eligible. In this way we will study a homogenous patient population with GIST that (usually) responds very well to initial TKI treatment. Therefore, the KIT mutation status must be known. Patients can enter the study at any time point of their disease trajectory. Patients included in GALLOP-11 will have follow-up as described in the European Society of Medical Oncology and Dutch guidelines but with blood draws for ctDNA assessment at similar time points.

The primary objective is the negative predictive value (NPV) of the ddPCR assay result in relation to the results of the CT-scan and/or MRI scan (according to RECIST 1.1) at the same time point. Concordance of these results will be determined, from which the negative predictive value (NPV) of our ddPCR assay will be calculated. This is considered the most important value, as the most harmful scenario would be to miss progressive disease because not seen on ctDNA while it could have been seen on CT (and/or MRI). That would mean that ctDNA analysis is not reliable enough to replace CT-scan (and/or MRI) follow-up in the future.

To determine the negative predictive value, at least 250 patients need to have an evaluable follow-up strategy. To pursue a solid follow-up period within an achievable timeline, patients with at least four ctDNA measurements, accompanied by a CT-scan (and/or MRI scan), will be considered evaluable for the NPV analysis. Patients who have progression within four scans are always evaluable, since a positive outcome outweighs negative outcomes because it is known that ctDNA should have had measured change once it is seen on CT-scans (and/or MRI scans).

Inclusion criteria

  1. Patients with GIST with a biopsy confirmed primary KIT exon 11 mutation covered by our KIT exon 11 ddPCR assay (mutation/deletion within target sequence of c.1665_1736);
  2. Patients with an indication for at least 4 CT-scans concomitant with regular laboratory examination in a neoadjuvant, adjuvant and/or palliative care trajectory within the time frame of the study;
  3. Age ≥18 years;
  4. Written informed consent provided

Exclusion criteria

  1.  Patients who are unable to comply with study procedures and follow up

  14. 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.

15. 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)
  1. 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.
  2. Before patient registration/randomization, written informed consent must be given according to ICH/GCP, and national/local regulations.

Dutch title

De waarde van een risicovoorspellingstool (PERSARC) voor effectieve behandelbeslissingen voor patiënten met wekedelen sarcomen.

Acronym

VALUE-PERSARC

Reference code

NL76563.058.21

Intervention model

High-grade extremity STS patients will either receive standard care (control group) or care with the use of PERSARC; i.e. PERSARC will be used in multidisciplinary tumour boards to guide treatment advice and in consultation in which the oncological/orthopaedic surgeon informs the patient about his/her diagnoses and discusses the benefits and harms of all relevant treatment options (intervention group).

Full description

Currently, there is no consensus about the optimal treatment for patients with high grade soft tissue sarcomas (STS) which are localized in the extremities. To ensure overall survival, there is a tendency to operate with wide resection margins, but this has a high impact on quality of life especially when limb function must be sacrificed. (Neo)adjuvant radiotherapy allows for narrower surgical margins but is associated with significant short -and long-term side-effects. As evidence on the best treatment is lacking, treatment choice for individual patients should be driven by their weighing of the benefits and harms of the treatment options in light of their personal situation.
However, current treatment decision-making in STS care is one-size fits all, and not informed by individualized risks of treatment options and patients’ preferences. Consequently, there is no guarantee that patients with STS will receive treatment that is appropriate for their situation, and patients experience uncertainty about which treatment is best for their personal situation (decisional conflict).
From literature it is known that decision supporting interventions contribute to a better informed choice and less decisional conflict. Therefore, our research group developed a validated personalized risk assessment tool (Personalised Sarcoma Care: PERSARC) which provides patients and STS professionals insight into the personalized risks and benefits of each treatment option based on patient’s age, tumor size, tumor depth and histology in their decision-making process.
It is hypothesized that use of PERSARC leads to significantly less decisional conflict in patients and more informed decisions compared to usual care (treatment decisions without use of PERSARC) by reducing the uncertainty regarding risks and benefits of treatment options in high-grade extremity STS patients.

Inclusion criteria

Patients (>= 18 years) with primarily diagnosed (histologically confirmed) grade 2-3 extremity STS, who do not have a treatment plan yet and will be treated with curative intent. Patients with sarcoma subtypes or treatment options other than those mentioned in the PERSARC app are unable to participate. Furthermore, patients need to be Dutch fluency and literacy and mentally competent.

Exclusion criteria

  1. Patient that are treated without curative intent
  2. Patient that needs to be treated with chemotherapy or isolated limb perfusion
  3. Patients were surgery is not indicated
  4. Sarcoma subtypes not mentioned in the PERSARC app

Full description

The investigators will follow the EORTC QLG questionnaire development guidelines. First, a computerized search of the academic literature will be performed to identify all relevant HRQoL issues for and existing HRQoL questionnaires currently used among patients with sarcoma. In parallel, semi-structured interviews will be conducted worldwide with patients with sarcoma(N=179) and health care professionals (HCPs; N=35; phase 1a). The patient sample will be stratified to capture diversity across the sarcoma population tumour location (extremities, axial, head and neck, thorax, retroperitoneal/intra-abdominal and gynecological), stage (localized vs. metastatic disease ) and type or lines of treatment.

This list of HRQoL issues generated by the a) literature search, b) relevant items from the Item Library, and c) semi-structured patient and HCP interviews, and will be consolidated into a comprehensive list of issues for all languages of collaborating countries.

In phase 1b, the new list of HRQoL issues will be presented to another group of patients with sarcoma(N=475) and HCPs (N=72). Patients and HCPs will be asked to rate the HRQoL issues on relevance (4point Likert scale) and to prioritize the 10 most important issues.

Inclusion criteria

  1. Age at diagnosis 18 years or older
  2. Having a confirmed diagnosis of sarcoma

Exclusion criteria

  1. Having any psychiatric condition or cognitive impairment that would hamper participation in interview/completion of self-reported questionnaires.
  2. Patients with a Gastrointestinal Stroma Tumour (GIST) diagnosis, as they are quite unique in terms of type of disease and treatment.
  3. Patients with Kaposi sarcoma, as this disease occurs quite often in people with AIDS
  4. Patients with Carcinosarcoma as this disease is generally seen as a carcinoma

Intervention model

Randomization between the standard arm A of 50 Gy in 5 weeks or arm B with hypofractination of 14x3Gy

Full description

Currently, soft tissue sarcomas (STS) are preoperatively irradiated in a conventionally fractionated regimen of 25 x 2 Gy in five weeks. Recent radiobiological investigations, however, suggest sensitivity to (modest) hypofractionation. Within this study, patients will be randomized to receive either the conventional schedule of 25 x 2 Gy or a shorter preoperative regimen of 14 x 3 Gy, in the hypothesis that both the postoperative wound complication rate until 30 days after surgery, as well as the local control probability at two years are comparable in both arms.

Inclusion criteria

  1. Histologically confirmed newly diagnosed intermediate to high grade soft tissue sarcoma localized to the extremities, trunk and chest wall or the head and neck area, for which the standard treatment is a combination of and radiotherapy and surgery (deep seated and/or > 5cm in largest tumor diameter and/or an anticipated close resection margin and/or grade II/III according to the FNCLCC definition)
  2. Absence of regional and/or distant disease. Patients staged by at least a CT scan of the chest (. Staging may also be performed by FDG-PET scanning and or total body MRI scans. Patients with an uncertain metastatic status (e.g. small indifferent lung nodules) and patients with a low metastatic burden not precluding the application of both preoperative radiotherapy and definitive surgery, are allowed to participate
  3. WHO Performance Status ≤ 2
  4. Able and willing to undergo preoperative radiotherapy
  5. Able and willing to undergo definitive surgery
  6. Able and willing to comply with regular follow-up visits
  7. Able and willing to complete patient reported outcome questionnaires (health-related quality of life and cost effectiveness)

Exclusion criteria

  1. Prior malignancies; except another malignancy and disease-free for ≥ 5 years, or completely resected non-melanomatous skin carcinoma or successfully treated in situ carcinoma
  2. Patients with recurrent sarcomas who underwent prior radiotherapy to the target lesion (if the primary sarcoma was managed by surgery only and no perioperative RT, patients are eligible)
  3. Ewing sarcoma and other PNET family tumors, rhabdomyosarcomas (both pediatric and adult), osteosarcomas
  4. Any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial

Towards a Minimally Invasive Approach of Atypical Lipomatous Tumors: the MINIMALIS trial

To develop a minimally invasive approach of both diagnosing and treating atypical lipomatous tumors, saving these patients a biopsy, surgery-related complications and morbidities amongst others.

Period

06/24/2020 until 06/24/2028

Dutch title

Op weg naar een minimaal invasieve benadering van atypische lipomateuze tumoren: de MINIMALIST studie

Acronym

MINIMALIST

Intervention model

Prospective single center observational cohort study. Two-arm parallel assignment (active surveillance or surgery).

Full description

Rationale: Patients with an atypical lipomatous tumor (ALT) have an excellent prognosis, approaching 100% survival after 10 years of follow-up. Currently, we might be ‘overtreating’ these patients with surgery and radiotherapy, thereby inducing morbidity and even mortality. Despite this excellent prognosis, active surveillance is barely applied in these patients. Furthermore, survival might not be the only appropriate outcome to measure, and other outcomes, such as health-related quality of life (HRQoL), might have become more relevant. Second, it can be very difficult to distinguish between ALTs and lipomas based on imaging. Therefore, these patients currently need a painful and invasive biopsy for pathological examination to make the distinction. Finally, due to the rarity and heterogeneity of liposarcomas, it is a challenge to collect a large homogeneous set of tissue samples for translational research.

Objective: The aim is to develop a minimally invasive approach of both diagnosing and treating ALTs, saving these patients a biopsy, surgery-related complications and morbidities amongst others. As a first step towards a minimally invasive diagnosis, a radiomics model was developed on a retrospective cohort to distinguish lipomas from ALTs based on MRI scans. In the current study, one of the objectives is to prospectively validate this radiomics model. Second, to prevent the ‘overtreatment’ of ALT patients, the aim is to explore the feasibility and safety of active surveillance (AS) as a treatment option for ALTs, including evaluating the HRQoL. Lastly, the objective is to build a biobank of the biopsies and, if applicable, resection specimens obtained during the study for future translational research.

Inclusion criteria

  1. Aged ≥18 years
  2. Primary or recurrent lipomatous tumor suspected for lipoma or atypical lipomatous tumor
  3. Adequate understanding of the Dutch or English language (to fill out the HRQoL questionnaires)

Exclusion criteria

  1. Tumor localization in the mediastinum, retroperitoneum or testis/scrotum
  2. Diagnosis through excisional biopsy
  3. Any type of treatment for the current tumor (i.e. in case of recurrence, treatment of the prior tumor(s) is allowed)
  4. Signs/suspicion of dedifferentiation in the biopsy specimen at time of diagnosis
  5. Unable to undergo regular MRI-scans (for example because of a pacemaker, claustrophobia)
  6. Systemic treatment for any other concurrent malignancy
  7. Currently receiving radiotherapy at affected site for other concurrent disease
  8. Incapable to understand the study, to sign informed consent or to fill out the HRQoL-questionnaires

Cemiplimab treatment in patients with locally advanced and metastatic secondary angiosarcomas

To evaluate the overall response rate after 24 weeks of cemiplimab treatment in patients with locally advanced or metastatic secondary angiosarcomas

Period

10/01/2021 until 10/01/2025

Dutch title

Behandeling met cemiplimab in patiënten met lokaal vergevorderd en/of uitgezaaid secundair angiosarcoom

Reference code

NCT04873375

Intervention model

Single group assignment

Full description

The purpose of this study is to evaluate the overall response rate after 24 weeks of cemiplimab treatment in patients with locally advanced or metastatic secondary angiosarcomas

Inclusion criteria

  1. Adult patient aged ≥ 18 years
  2. Histologically confirmed diagnosis of progressive unresectable locally advanced or metastatic secondary angiosarcoma
  3. Patients in the first line of systemic treatment unfit for chemotherapy and patients in advanced lines of systemic treatment
  4. Measurable disease per RECIST 1.1 or per physical examination / daylight photography (WHO Offset Publication No. 48) as determined by the investigator]
  5. Tumour tissue material available (archival or recent tumour biopsy)
  6. WHO ECOG 0-2
  7. Hepatic function:
    • Total bilirubin ≤ 1.5 x ULN (if liver metastases: ≤ 3 x ULN).
    • Transaminases ≤ 3 x ULN (if liver metastases: ≤ 5 x ULN).
    • Patients with Gilbert’s Disease and total bilirubin up to 3x ULN may be eligible after communication with and approval from the medical monitor
    • Alkaline phosphatase ≤ 2.5 x ULN (if liver OR bone metastases ≤5 x ULN)
  8. Renal function: serum creatinine ≤ 2 x ULN or estimated CrCl > 30 mL/min.
  9. Creatine phosphokinase (CPK) (also known as CK [creatine kinase]) elevation ≤ grade 2
  10. Bone marrow function:
    • Hemoglobulin ≥ 9.0 g/dL
    • ANC ≥ 1.5 x 109/L
    • Platelet count ≥ 75 x 109/L
  11. Expected life expectancy of at least 3 months as judged by the investigator

 

Exclusion criteria

  1. Ongoing or recent (within 5 years) evidence of significant autoimmune disease that required treatment with systemic immunosuppressive treatments, which may suggest risk for irAEs. The following are not exclusionary: vitiligo, childhood asthma that has resolved, type 1 Diabetes mellitus, residual hypothyroidism that required only hormone therapy, or psoriasis that does not require systematic treatment
  2. Prior treatment with immune checkpoint inhibitors
  3. Continuous immunosuppressive corticosteroid treatment (doses > 10 mg prednisone daily or equivalent) within 4 weeks prior to the first dose of cemiplimab. Note: patients who require a brief course of steroids (e.g. as prophylaxis for imaging studies) are not excluded
  4. Active uncontrolled infection requiring therapy, including infection with HIV, active infection with HBV or HCV
  5. History of pneumonitis within the last 5 years
  6. Untreated brain metastasis(es) that may be considered active
    • Note in clarification: Patients with previously treated brain metastases may participate provided that the lesion(s) is (are) stable (without evidence of progression for at least 6 weeks on imaging obtained in the screening period), and there is no evidence of new or enlarging brain metastases, and the patients do not require any immunosuppressive doses of systemic corticosteroids for management of brain metastasis(es) within 28 days of the first dose of cemiplimab
  7. Patients with allergy or hypersensitivity to cemiplimab or to any of the excipients must be excluded. Specifically, because of the presence of trace components in cemiplimab, patients with allergy or hypersensitivity to doxycycline or tetracycline are excluded
  8. History of documented allergic reactions or acute hypersensitivity reaction attributed to antibody treatments
  9. Patients with a history of solid organ transplant (patients with prior corneal transplants may be allowed to enroll after discussion with and approval from the medical monitor)
