Plain-language summary
The dose escalation phase of this trial identifies the safety, side effects and best dose of ceralasertib (AZD6738) when given in combination with trastuzumab deruxtecan (DS-8201a) in treating patients with solid tumors that have a change (mutation) in the HER2 gene or protein and have spread to other places in the body (advanced). The dose expansion phase (phase Ib) of this trial compares how colorectal and gastroesophageal cancers with HER2 mutation respond to treatment with a combination of ceralasertib and trastuzumab deruxtecan versus trastuzumab deruxtecan alone. Ceralasertib may stop the growth of tumor cells and may kill them by blocking some of the enzymes needed for cell growth. Trastuzumab deruxtecan is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called deruxtecan. Trastuzumab attaches to HER2 positive cancer cells in a targeted way and delivers deruxtecan to kill them. Ceralasertib and trastuzumab deruxtecan may be safe, tolerable and effective in treating patients with advanced solid tumors expressing the HER2 protein or gene.

Inclusion Criteria:
* DOSE-ESCALATION PHASE: Must have histologically confirmed advanced solid tumor including but not restricted to breast cancer, gastric or gastroesophageal cancer, colon cancer, endometrial cancer, salivary gland tumors, and hepatobiliary tumors
* DOSE-EXPANSION PHASE: Must have histologically confirmed advanced/metastatic gastroesophageal cancer (cohort A) or colorectal cancer (cohort B)
* DOSE-EXPANSION PHASE: Patients must have a biopsiable lesion and provide consent for on treatment biopsy
* Age \>= 18 years. Because no dosing or adverse event data are currently available on the use of AZD6738 in combination with DS-8201a in patients \< 18 years of age, children are excluded from this study
* Patients must have HER2-positive or HER2-expressing tumors determined by a Clinical Laboratory Improvement Act (CLIA)-certified laboratory. As a rule, for HER2 immunohistochemistry (IHC) scoring system trastuzumab for gastric cancer (TOGA) criteria used for gastric/gastroesophageal junction (GEJ) cancers will be employed (Note: in escalation phase, for breast cancer patients that are included, breast cancer criteria can be used). Specific requirement of HER2 status is outlined below:
* HER2 expression (1-3+) by IHC locally and confirmed centrally OR
* HER2 expression (1-3+) by IHC tested centrally OR
* HER2 amplification based on fluorescence in situ hybridization (FISH) or next generation sequencing
* Must have received at least one line of systemic chemo…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Since this is a Phase 1 trial combining DS-8201a and AZD6738, the main goal is still figuring out the safest dose — what does that mean for how much is known about the risks versus potential benefits for someone in my situation?
2The trial is listed as 'active not recruiting,' which means they're no longer enrolling new patients — is there a related or follow-on study that I might actually be eligible to join, given my cancer type and HER2 status?
3One of the things this trial is measuring is how the combination affects DNA damage and repair pathways in tumor tissue — would that require extra biopsies, and is that something my current health situation could handle?
4DS-8201a, also known as trastuzumab deruxtecan, has been linked to a serious lung side effect called interstitial lung disease in other studies — is that a risk worth weighing carefully given my overall health, and how would my doctors monitor for it?
5Given that this trial covers many different HER2-expressing cancer types, how does the evidence from this combination compare to whatever standard treatment options currently exist for my specific cancer type and stage?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
