Inclusion criteria

  1. Age ≥18 years.

Exclusion criteria

Exclusion Criteria:

  1. Presence of other well-documented driver gene mutations (e.g., ALK fusion, ROS1 fusion, KRAS activating mutations, MET exon 14 skipping, mutations, RET fusion).
  2. Histological or phenotypic transformation (e.g., NSCLC to SCLC transformation, epithelial-to-mesenchymal transition) confirmed by tumor tissue obtained within 6 months prior to first dose.
  3. ≥ Grade 2 toxicities (per v6.0) attributed to prior anti-tumor therapy (excluding alopecia and stable neurotoxicity).
  4. History of other primary .
  5. Inadequate bone marrow reserve or hepatic/renal organ function.
  6. cardiac abnormalities or severe/uncontrolled/active cardiovascular disease.
  7. Poorly controlled diabetes mellitus or hypertension.
  8. Significant clinical bleeding tendency or history of severe arterial/venous thromboembolic events.
  9. Severe or uncontrolled active infection.
  10. Continuous systemic therapy (>30 days) within 30 days prior to first dose, or requirement for long-term (≥30 days) corticosteroid use.
  11. Active infectious diseases (e.g., active virus [HBV] infection).
  12. Clinically significant gastrointestinal disorders.
  13. Hepatic encephalopathy, hepatorenal syndrome, or cirrhosis ≥ class B.
  14. Other pulmonary diseases that may interfere with assessment or management of drug-related pneumotoxicity.
  15. History of severe neurological or psychiatric disorders.
Terms in these criteria, in plain language(10)

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.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

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.

HER2

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.

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.

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.

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.

Corticosteroids (steroids)

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.

Hepatitis B tests

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.

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.

Study arms

  • Experimental
    HS-10504 group

    Drug: HS-10504

  • Active comparator
    Platinum-Based Doublet Chemotherapy Group

    Drug: platinum-based doublet chemotherapy (Pemetrexed and Cisplatin/Carboplatin)

Interventions

  • HS-10504 tablet

  • Drugplatinum-based doublet chemotherapy (Pemetrexed and Cisplatin/Carboplatin)

    Participants will receive 4 cycles of standard platinum-based doublet chemotherapy (selected by the investigator based on participant's condition and tolerance): * Option 1: Pemetrexed 500 mg/m² IV infusion + Cisplatin 75 mg/m² IV infusion on Day 1 of each 21-day cycle. * Option 2: Pemetrexed 500 mg/m² IV infusion + Carboplatin AUC 5 IV infusion on Day 1 of each 21-day cycle. * Substitution Rule: Cisplatin and carboplatin may be substituted if intolerable due to safety, while maintaining 4 total cycles of platinum-based therapy.
