A Phase 2 interventional study of HG146 in Adenoid Cystic Carcinoma and Head and Neck Cancer, sponsored by HitGen Inc.. Recruiting at 1 site in China. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-09-21.
Sponsored by HitGen Inc. · Phase 2, Interventional, and Treatment
This is a Phase II, open-label, non-randomized, multicenter study to evaluate the clinical efficacy and safety of HG146 in participants with recurrent or metastatic adenoid cystic carcinoma. This study is divided into two stages. 40 participants will be enrolled in the first stage. The efficacy and safty data will apply to make go or no go decision. Then the second stage will continue to enroll 100 Particapants.
86 studies on the registry are indexed under Carcinoma, Adenoid Cystic; 26 are open to participants now.
This study's planned enrollment of 140 is above the median of 37 across 76 interventional studies indexed under Carcinoma, Adenoid Cystic.

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.
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.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.
Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.
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.
The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Started Dec 2024 (actual). Primary completion is estimated for Dec 2028, 48 months after the start.
Of 28 phase 2 interventional studies under Carcinoma, Adenoid Cystic, half reached primary completion within 43 months of starting (the median), counting those still running; a quarter within 32 and three quarters within 67. This study's planned 48 months is above that.
