Adenoid Cystic Carcinoma and Carbon Ion Only Irradiation (ACCO)

November 29, 2023 updated by: Klaus Herfarth, MD, Heidelberg University
Adenoid cystic tumors are rare tumors of the head and neck region. Despite their slow growth, re-irradiation is often necessary due to the high metastatic risk. Patients are usually irradiated with photons or, as here at the Heidelberg University Hospital, with a combination of carbon ions and photons. So far, there is no data from Europe available for the sole irradiation with carbon ions. The present ACCO (Adenoid Cystic Carcinoma and Carbon ion Only irradiation) study, a prospective, open-label, phase II, single-arm, investigator-initiated study, will therefore investigate the sole radiotherapy of carbon ions in this tumor entity. Irradiation is applied - significantly shorter than the combination therapy - in about 4 weeks (22 fractions); patients are followed up for further 5 years after the start of therapy. Carbon ions alone are expected to increase local tumor control rates from 60% to 70% after 5 years (primary objective criterion of this study). In order to reject the null hypothesis with a power of 80% and a significance level of 5%, 175 patients are included (including a drop-out rate of 15%). Secondary objective criteria are progression-free survival, overall survival, acute and late toxicity, and quality of life.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

  • Informed consent
  • KI > 60% or ECOG 0/1 (minimum: self-sufficiency, normal activity or work not possible)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
