Study summary

The primary objective is to evaluate the safety and tolerability of RC288; determine the maximum tolerated dose (MTD) and/or maximum administered dose (MAD) of RC288; and determine the recommended phase 2 dose (RP2D), and assess the efficacy of RC288 at the RP2D dose;

Inclusion criteria

  1. Voluntarily participate in this study, sign the form, and be able to adhere to the study protocol;
  2. Age between 18 and 75 years (including 18 and 75 years);
  3. PS score of 0 or 1;
  4. Expected survival ≥12 weeks;
  5. According to v1.1 criteria, based on imaging examinations, there is at least one measurable target lesion;
  6. Sufficient bone marrow, liver, kidney, and blood clotting function

Exclusion criteria

Exclusion Criteria:

  1. Pregnant, breastfeeding, or intending to become pregnant subjects.
  2. Subjects with .
  3. Subjects with unresolved toxicities from prior anti-tumor therapy not recovered to v6.0 Grade 1.
  4. Subjects with known or delayed allergic reactions to any component of the drug or similar drugs.
  5. Subjects with acute, chronic, or symptomatic infections.
  6. Subjects with uncontrolled cardiovascular diseases.
  7. Subjects with confirmed or suspected interstitial lung disease (ILD), drug-related pneumonia, radiation pneumonitis, severely impaired pulmonary function, or other pulmonary diseases.
  8. History of underlying pulmonary disease.
  9. Subjects with a history of cirrhosis ( B or C class).
  10. gastrointestinal disease.
  11. Subjects with uncontrolled diabetes ( ≥ 10%).
  12. Occurrence of hemorrhagic events of Grade ≥2 per NCI CTCAE (v6.0) within 4 weeks prior to screening; or clinical manifestations suggestive of a significant bleeding tendency within 4 weeks prior to screening.
  13. Imaging during the screening period shows tumor invasion or involvement of vital organs, with imaging evidence judged by the investigator to indicate a risk of bleeding or fistula formation.
  14. History of arterial/venous thromboembolic events within 6 months prior to the first dose.
  15. Presence of pericardial effusion or cardiac tamponade, or third-space fluid accumulation that, in the investigator's judgment, cannot be stably controlled by drainage or other methods.
  16. History of active disease requiring systemic therapy within the past 2 years.
  17. History of other invasive within 5 years prior to the first dose, or evidence of residual disease from any previously diagnosed malignancy.
  18. History of other acquired or congenital immunodeficiency diseases, or history of organ transplantation.
  19. History of or current poorly controlled psychiatric disorder.
  20. Poor compliance, and patients who are expected to be unable to cooperate with the completion of trial procedures.
  21. Presence of any other disease, metabolic abnormality, physical examination finding, or laboratory abnormality that, in the investigator's judgment, gives reasonable suspicion of a condition that contraindicates the use of the investigational drug, may affect the interpretation of study results, or places the patient at high risk.
  22. Local or systemic diseases not caused by malignancy, or diseases or symptoms secondary to the tumor, which may lead to higher medical risks and/or uncertainty in survival assessment.
Terms in these criteria, in plain language(12)

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.

Informed consent

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.

ECOG performance status

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.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

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.

RECIST

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.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

CTCAE grade

The US National Cancer Institute’s scale of how severe an adverse event is — any unwanted medical event during a study, such as a symptom, an illness or an abnormal test result, whether or not a treatment caused it. Whether it did is judged separately.

1
Mild.
2
Moderate.
3
Severe.
4
Life-threatening.
5
Death due to the event.

“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.

Hypersensitivity

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.

Investigational drug or device

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.

Child-Pugh class

A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Cancer (malignancy)

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.
