Studie zu Immuntherapie plus Tumorablation oder Bestrahlung bei Patienten mit Lebermetastasen eines Darmkrebs

Datenbasis: BASEC (Import vom 29.03.2024), WHO (Import vom 29.03.2024)
Geändert: 23.12.2023, 16:46
Krankheitskategorie: Dickdarm- und Mastdarmkrebs

Zusammenfassende Beschreibung der Studie (Datenquelle: BASEC)

Bei Patienten, welche an dieser Studie teilnehmen, werden ausgewählte Lebermetastasen entweder bestrahlt oder mit Radiofrequenzablation (Abtötung von Tumorgewebe durch Hitze) behandelt. Welche der beiden Methoden zur Anwendung kommt, entscheidet der behandelnde Arzt. Zeitgleich zur Bestrahlung oder Tumorablation erhalten die Teilnehmer die Medikamente Durvalumab und Tremelimumab. Bei diesen Medikamenten handelt es sich um Immuntherapien, welche das körpereigene Immunsystem zur Bekämpfung des Tumors aktivieren. Danach erhalten die Studienteilnehmer über ein Jahr alle 4 Wochen weiterhin das Medikament Durvalumab. Es ist die Hypothese der Studie, dass durch die Bestrahlung oder Tumorablation die Immuntherapie in ihrer Wirksamkeit verstärkt wird.

Inclusion/Exclusion Criteria (Datenquelle: WHO)


INCLUSION CRITERIA

- Histologically confirmed CRC

- Patients with CRC liver metastases, with or without extrahepatic disease, in which
curative treatment is not possible by resection and or local ablation/radiotherapy.

- = 18 years of age at time of study entry

- WHO performance status 0 to 1

- Body weight > 30kg

- Measurable disease according to RECIST 1.1

- Stable disease or partial remission by RECIST 1.1 criteria after at least 3 months
systemic therapy for CRC. Patients following first- or second-line treatment are
eligible. Note: if patient receives maintenance treatment after the first line
treatment, she/he remains eligible for this study

- Complete responders or partial responders with a 80% or more decrease in the sum of
measures (longest diameter for tumor lesions and short axis measure for nodes) of
target lesions following systemic therapy, taking as reference the sum of diameters
from baseline scan prior to initiation of first line therapy are excluded as well as
patients with almost complete cystic degeneration of liver metastases. Note: The
interval between last dose of systemic treatment and first dose of study drugs must be
maximum 8 weeks (in case bevacizumab was administered as part of the systemic
treatment, a minimum 21 days wash out period is required from last administration to
planned local ablative treatment initiation).

- Liver metastases amenable to ablation or stereotactic radiotherapy (SBRT) at
completion of systemic therapy:

- For SBRT: allowing a total ablated volume of at least 25 cm3 and a maximum of 40 cm3
with a maximum of two lesions treated with SBRT

- For RFA: allowing a total ablated volume of at least 25 cm3 and a maximum advised
volume of 120 cm3

- At least two measurable liver metastases, or at least 1 measurable liver metastasis
and 1 measurable extrahepatic lesion should remain untreated by ablation or SBRT to
allow response monitoring according to RECIST 1.1 and iRECIST.

- Limited extra hepatic disease is allowed, including up to 2 extra hepatic metastatic
sites, either lung, abdominal, pelvis, bone, or localized lymph node metastases. Each
will be counted separately as one site. So, two abdominal lesions will be counted as 1
extra-hepatic site; one lung and one abdominal lesion will be counted as two sites.
Individual extrahepatic lesions should be = 5 cm.

- Availability of tumor sample for biomarkers testing (MSI, PDL-1, etc) (archival tissue
from primary tumor or biopsy)

- Adequate normal organ and marrow function before initial systemic treatment as well as
at baseline as defined below:

- Absolute neutrophil count (ANC) = 1.5 x 109/L (> 1500 per mm3)

- Platelet count = 100 x 109/L (>100,000 per mm3)

- Serum bilirubin = 1.5 x institutional upper limit of normal (ULN). This will not apply
to subjects with confirmed Gilbert's syndrome (persistent or recurrent
hyperbilirubinemia that is predominantly unconjugated in the absence of hemolysis or
hepatic pathology), who will be allowed only in consultation with their physician.

- AST (SGOT)/ALT (SGPT) = 5 x institutional upper limit of normal

- Creatinine = 1.5 x institutional ULN or measured or calculated creatinine clearance
>40 mL/min by the Cockcroft-Gault formula (Appendix E)

- Hemoglobin = 9.0 g/dL at baseline

- Patient with following medical conditions are eligible:

- Patients with vitiligo or alopecia

- Patients with hypothyroidism (eg, following Hashimoto syndrome) stable on hormone
replacement

- Any chronic skin condition that does not require systemic therapy

- Patients with celiac disease controlled by diet alone

- No history of another malignancy or a concurrent malignancy. Exceptions include
patients who have been disease-free for 5 years, or patients with a history of
completely resected non-melanoma skin cancer or successfully treated in situ carcinoma
are eligible, for example cervical cancer in situ.

- Women of child bearing potential (WOCBP) must have a negative serum pregnancy test
within 72 hours prior to the first dose of study treatment. Note: women of
childbearing potential are defined as premenopausal females capable of becoming
pregnant (i.e. females who have had any evidence of menses in the past 12 months, with
the exception of those who had prior hysterectomy). However, women who have been
amenorrhoeic for 12 or more months are still considered to be of childbearing
potential if the amenorrhea is possibly due to prior chemotherapy, antiestrogens, low
body weight, ovarian suppression or other reasons.

- Patients of childbearing / reproductive potential should use adequate birth control
measures, as defined by the investigator, during the study treatment period and from
screening to 90 days after the last dose of durvalumab monotherapy or 180 days after
the last dose of durvalumab + tremelimumab combination therapy the last study
treatment. 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 (estrogen 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) Note: please refer to Appendix J for Clinical Trial Facilitation Group
(CTFG) guidelines.

- Female subjects who are breast feeding should discontinue nursing prior to the first
dose of study treatment, from screening to 90 days after the last dose of durvalumab
monotherapy or 180 days after the last dose of durvalumab + tremelimumab combination
therapy.

- Subject is willing and able to comply with the protocol for the duration of the study
including undergoing treatment and scheduled visits and examinations including follow
up.

- Before patient registration, written informed consent must be given according to
ICH/GCP, and national/local regulations
