A Phase 1/2 interventional study of AK138D1 and Ivonescimab in Non-Small Cell Lung Cancer, sponsored by Akeso. Recruiting at 1 site in China. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2026-07-29.
Sponsored by Akeso · Phase 1/2, Interventional, and Treatment
The goal of this clinical trial is to evaluate the safety, tolerability, and efficacy of AK138D1 as monotherapy or in combination with ivonescimab in patients with advanced non-small cell lung cancer.
Participants will receive study treatment with AK138D1 alone or in combination with ivonescimab, undergo safety assessments and tumor evaluations, and be followed for treatment tolerability, antitumor activity, and clinical outcomes.
This is a multicenter, open-label phase Ib/II study of AK138D1 as monotherapy or in combination with ivonescimab in patients with advanced non-small cell lung cancer. The phase Ib portion is designed to evaluate the safety, tolerability, and preliminary antitumor activity of AK138D1 in combination with ivonescimab. The phase II portion is designed to evaluate the safety and efficacy of AK138D1 as monotherapy or in combination with ivonescimab.

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.
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.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.
“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Started Jul 2026 (actual). Primary completion is estimated for Jun 2028, 23 months after the start.
Of 308 industry-sponsored phase 1/2 interventional studies under Carcinoma, Non-Small-Cell Lung, half reached primary completion within 58 months of starting (the median), counting those still running; a quarter within 39 and three quarters within 77. This study's planned 23 months is below that.
Counting every sponsor, half of 431 studies reached it within 63 months; a quarter within 42 and three quarters within 80.
