An observational study in Adenocarcinoma (NOS), Anal Cancer and Bladder Cancer, sponsored by AstraZeneca. Recruiting at 18 sites in United States. Open to participants aged 18 Years to 130 Years. Per ClinicalTrials.gov, last updated 2026-09-25.

This study will evaluate the effectiveness of T-DXd in patients with HER2-positive (IHC 3+) locally advanced, unresectable, or metastatic solid tumors who have received prior systemic treatment for metastatic or advanced disease and have no satisfactory alternative treatment options in a real-world setting in the US
This study is a multicenter, hybrid, observational study of approximately 100 prospectively enrolled patients with HER2-positive (IHC 3+) solid tumors in the US initiated on trastuzumab deruxtecan (T-DXd) as per FDA label in routine clinical practice and enrolled at the point of starting treatment with T-DXd. Patients with locally advanced, unresectable, or metastatic HER2-positive (IHC 3+) solid tumors who have received prior systemic treatment for metastatic or advanced disease and have no satisfactory alternative treatment options will be eligible for inclusion. Patients with breast, colorectal, non-small cell lung cancer (NSCLC), gastric/gastroesophageal junction (GEJ) cancers, and haematological malignancies are not eligible for this study.
Approximately 30 sites will be selected including community oncology practices, hospital systems and academic medical centers (AMCs), with a focus on enrolling a patient population representative of real-world care with the majority of patients from community settings. The primary objective of the study is to assess real world response rate and real world duration of response, and the secondary objective is to assess real world time to treatment discontinuation and real world time to next treatment.

The study will enroll patients for whom a clinician decision has been made for treatment with T-DXd as part of routine clinical practice and in line with the FDA label, but who have not yet started therapy with T-DXd

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
HER2 is a protein, made from the ERBB2 gene, that drives the growth of some cancers. A study may look for a level of the protein, extra copies of the gene, or a particular change in it.
In breast cancer, protein tests are read as HER2-positive, HER2-low or HER2-negative; other cancers use their own rules. Check which test result the study requires.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Counting every sponsor, half of 139 studies reached it within 50 months; a quarter within 33 and three quarters within 94.
