A Phase I Study to Evaluate the Safety, Tolerability, and PK of HLX43 in Advanced/Metastatic Solid Tumors
Bu çalışma, ileri evre veya metastatik solid tümörleri (katı organ tümörleri) olan hastalarda HLX43 adlı ilacın güvenliğini, tolere edilebilirliğini ve vücuttaki davranışını (farmakokinetik) değerlendirmektedir. Çalışmaya 18-75 yaş arası, standart tedavisi tükenmiş veya uygun standart tedavisi bulunmayan hastalar (küçük hücreli dışı akciğer kanseri dahil) katılmaktadır. Faz 1 aşamasında yürütülmekte ve davetle katılım almaktadır.

In phase Ia, enroll patients with histologically or cytologically confirmed advanced/metastatic malignant solid tumors, who are refractory to standard treatment, or for which no standard treatment is available; In phase Ib Cohort 1: enroll patients with histologically or cytologically confirmed advanced/metastatic NSCLC, who are refractory to standard treatment, or for which no standard treatment is available (The standard treatment for squamous NSCLC is defined as platinum-containing chemotherapy combined with immune checkpoint inhibitor \[ICI\]. The standard treatment for non-squamous NSCLC with known EGFR mutations is defined as EGFR inhibitors and platinum-containing chemotherapy. The standard treatment for patients with non-squamous NSCLC without EGFR mutations is defined as platinum-containing chemotherapy combined with immune checkpoint inhibitor \[ICI\] therapy); Cohort 2: enroll patients with histologically or cytologically confirmed advanced/metastatic TC, who are refractory to first line platinum based standard treatment; Cohort 3: enroll patients with histologically or cytologically confirmed advanced/metastatic NSCLC, who are refractory to standard treatment and docetaxel treatment (The standard treatment for squamous NSCLC is defined as platinum-containing chemotherapy combined with immune checkpoint inhibitor \[ICI\]. The standard treatment for non-squamous NSCLC with known EGFR mutations is defined as EGFR inhibitors and platinum-containing chemotherapy. The standard treatment for patients with non-squamous NSCLC without EGFR mutations is defined as platinum-containing chemotherapy combined with immune checkpoint inhibitor \[ICI\] therapy); Cohort 4: enroll patients with histologically or cytologically confirmed stage IIIB, IIIC, or IV NSCLC that cannot be treated with surgery or radiotherapy; positive PD-L1 expression (PD-L1 positive is defined as TPS ≥ 1%; PD-L1 expression is subject to the central laboratory result) and no EGFR sensitizing mutation or ALK/ROS gene rearrangement; no previous systemic anti-tumor therapy for NSCLC (Patients who have received adjuvant or neoadjuvant therapy are allowed to be enrolled if the adjuvant/neoadjuvant therapy has been completed at least 6 months before the diagnosis of stage IIIB, IIIC, or IV NSCLC);
4. At least one measurable lesion as per RECIST 1.1 within 4 weeks prior to the first administration;
5. An ECOG performance status score of 0-1 within 7 days prior to the first administration;
6. Life expectancy \> 3 months;
7. The following conditions must be met in terms of the time of the first administration of the investigational product: at least 28 days from the previous major surgery, medical device treatment, locoregional radiotherapy (except for palliative radiotherapy for bone lesions), cytotoxic chemotherapy, immunotherapy, or biological product therapy; at least 14 days from the previous small molecule targeted drug therapy and previous hormone therapy; at least 7 days from the administration of the traditional Chinese medicine for anti-tumor indications, or minor surgery; and recovery of treatment-induced AEs to grade ≤ 1 (CTCAE v5.0, except for alopecia);
8. Subjects who agree to provide archived tumor tissue specimens that meet the testing requirements (either from the most recent surgery or biopsy, preferably within 2 years) or agree to undergo a biopsy to collect tumor tissue for PD-L1 expression testing; Note: Formalin-fixed paraffin-embedded (FFPE) tumor samples (paraffin blocks or unstained sections, which must meet the quality control criteria for testing) collected from sites not receiving radiotherapy during the most recent surgery or biopsy at or after the diagnosis of malignant tumor and pathological reports of such specimens shall also be provided.
9. Adequate organ functions as confirmed by laboratory tests within 7 days prior to the first administration of the investigational product (no blood transfusions or treatment with granulocyte colony-stimulating factor within 14 days prior to the first administration).
10. For patients with hepatocellular carcinoma, Child-Pugh score must be A;
11. Male and female subjects with child-bearing potential must agree to use at least one highly effective contraception method during the study and within at least 6 months (at least 8 months for Japanese subjects) after the last administration of the investigational product; female subjects of childbearing age must have a negative pregnancy test within 7 days prior to enrollment.
Exclusion Criteria:
Subjects who meet any of the following criteria are not allowed to be enrolled:
1. Patients who have history of other malignant tumors within 2 years prior to the first administration, except for cured cervical carcinoma in situ or cutaneous basal cell carcinoma;
2. Patients who previously have immune-related adverse events (irAEs) ≥ grade 3 in immunotherapy;
3. Patients who have history of (non-infectious) interstitial lung disease (ILD) requiring steroids, or current ILD, or suspected ILD that cannot be ruled out by imaging at screening;
4. Subjects who are known to have anaphylaxis to protein preparations/monoclonal antibodies or are allergic to any component in the formulation of the investigational product;

6. Subjects who have any poorly-controlled cardiovascular and cerebrovascular clinical symptoms or diseases, including but not limited to: (1) NYHA Class II or greater heart failure or left ventricular ejection fraction (LVEF) \< 50%; (2) unstable angina pectoris; (3) myocardial infarction or cerebrovascular accident within 6 months (except for lacunar infarction, slight cerebral ischemia, or transient ischemic attack); (4) poorly controlled arrhythmia (including QTc intervals ≥ 450 ms for males and ≥ 470 ms for females) (QTc intervals are calculated by Fridericia's formula); (5) poorly-controlled hypertension (systolic blood pressure \> 150 mmHg and/or diastolic blood pressure \> 100 mmHg after active treatment);
7. Patients who have been assessed as unsuitable for inclusion by the investigator, due to brain metastases, spinal cord compression, or cancerous meningitis with clinical symptoms, or uncontrolled brain or spinal cord metastases that have been evidenced; Note: Patients with asymptomatic or stable brain metastases, spinal cord compression, or cancerous meningitis as judged by the investigator are allowed to be enrolled;
