Trial summary

It has been showed that alkylating chemotherapy, particularly the widely used agent temozolomide, may cause high tumor mutational burden (TMB) in certain tumors by causing inactivating mutations in the DNA mismatch repair (MMR) system. Read more about this study

About this study

Official title: Longitudinal Biomarker Study in Endocrine Neoplasms to Study Acquired Resistance to Alkylator Chemotherapy

It has been showed that alkylating chemotherapy, particularly the widely used agent temozolomide, may cause high tumor mutational burden (TMB) in certain tumors by causing inactivating mutations in the DNA mismatch repair (MMR) system. This can cause therapy resistance and tumor progression but may also predict response for immunotherapy. Hypermutation is very uncommon in neuroendocrine tumors. However, small studies indicate that around 30% of pancreatic tumors develop high TMB after alkylating chemotherapy. The aim of this study is therefore to study the occurrence and frequency of DNA hypermutation after alkylating chemotherapy in endocrine neoplasms and to investigate non-invasive methods that may capture the development of hypermutation (imaging, ctDNA etc.).

This is a prospective multicenter study. 94 patients from Swedish endocrine cancer centers in Uppsala, Stockholm, Göteborg and Lund will be included and divided into two groups. Group A will include patients that are about to start treatment with alkylating chemotherapy. Blood samples for liquid biopsy will be collected at baseline and at follow-up and if the tumor progresses, tissue biopsy will be obtained from two different lesions and analyzed with GMS560. Group B will include patients experiencing tumor progression after having received alkylating chemotherapy at any point in their disease course before. At inclusion, both liquid and tissue biopsy will be obtained and analyzed as described above.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of pancreatic neuroendocrine tumor patients with hypermutation and/or mismatch repair deficiency after treatment with alkylating chemotherapy

    Proportion of pancreatic neuroendocrine tumor patients with hypermutation (tumour mutation burden >30) and/or mismatch repair deficiency (by DNA sequencing or immunohistochemistry) in tissue or liquid biopsy at any timepoint after treatment with alkylating chemotherapy.

    Measured: Through study completion, an average of 2 years.

Questions about this trial

What is this clinical trial studying?

An observational study of Neuroendocrine (NE) Tumors and Endocrine Cancer, run by Uppsala University at 1 site in Sweden.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 14 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Lovisa Falkman, MD (+46186110000, lovisa.falkman@uu.se), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of pancreatic neuroendocrine tumor patients with hypermutation and/or mismatch repair deficiency after treatment with alkylating chemotherapy (time frame: Through study completion, an average of 2 years.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Aug 2025.
