Evaluating NBL-020 Injection for Advanced Malignant Tumors

A Phase I Study to Evaluate the Safety, Tolerability, Pharmacokinetic Characteristics, and Preliminary Anti-tumor Activity of NBL-020 Injection in Subjects With Advanced Malignant Tumors.

This study is testing a new injection called NBL-020 to see if it is safe and effective for people with advanced malignant tumors.

What this trial studies

This study evaluates the safety and tolerability of NBL-020 injection in patients with advanced malignant tumors. It consists of two parts: a dose escalation phase to determine the maximum tolerable dose and a dose expansion phase to further assess the efficacy and safety of the determined doses. Participants will receive the injection every three weeks, with adjustments made based on safety and efficacy data. The study aims to gather critical information on dosing regimens and potential therapeutic benefits of NBL-020.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with confirmed advanced solid tumors or skin T-cell lymphoma who have exhausted standard treatment options.

Not a fit: Patients with non-malignant tumors or those who are not able to provide adequate tumor tissue samples may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced malignant tumors.

How similar studies have performed: While this approach is novel, similar studies targeting advanced malignant tumors have shown promise in evaluating new therapies.

Eligibility criteria

Inclusion Criteria:

1. Those who are 18 years old or older (based on the date of signing the informed consent form) and voluntarily sign the informed consent form;
2. For malignant tumors confirmed by histology or cytology, only solid tumor subjects were included in dose escalation study. In addition to solid tumors, additional skin T-cell lymphoma subjects could be considered in dose expansion study;
3. Must be willing to provide tumor tissue samples that can meet the requirements of biomarker testing (fresh biopsy tissue is preferred; if fresh tissue cannot be provided, tumor tissue samples within 2 years can be provided), and tumor samples will be tested by the central laboratory. If tumor tissue does not meet the testing requirements, additional biopsy may be required;
4. If the standard treatment fails or toxicity is intolerable, or there is no standard treatment, the enrolled subjects must fully recover from previous treatment, with an AE level of 0-1 (except for alopecia, pigmentation, or other toxicity that the researcher believes is not a safety risk to the subjects);
5. For subjects with solid tumor, there is at least one measurable lesion that meets the RECIST 1.1 standard at the baseline (the measurable lesion area has not received radiotherapy in the past, or there is evidence that the lesion has unequivocal progressed after radiotherapy);
6. ECOG PS score 0-1 points;
7. Expected survival time ≥ 3 months (12 weeks);
8. Good organ function (no blood transfusion or growth factor support treatment received within 2 weeks before blood collection for relevant examinations), including:

   1. Absolute value of neutrophils (ANC) ≥ 1.5 × 10\^9/L；
   2. Hemoglobin (Hb) ≥ 90 g/L;
   3. Platelets ≥ 100 × 10\^9 /L;
   4. Creatinine ≤ 1.5 times the upper limit of normal value (ULN) or creatinine clearance rate ≥ 50 mL/min (Cockcroft Fault formula);
   5. Total bilirubin ≤ 1.5 × ULN (≤ 3 × ULN for Gilbert's syndrome）;
   6. Alanine aminotransferase (AST) and aspartate aminotransferase (ALT) ≤ 2.5 × ULN (≤ 5 × ULN for subjects with liver metastasis);
   7. Coagulation function: activated partial thromboplastin time(APTT), international standardized ratio (INR) ≤ 1.5 × ULN.

   Note: If the subject does not meet the requirements during screening, a re-examination is allowed.
9. The subjects must agree to take effective contraceptive measures from the signing of the informed consent form until 6 months after the last administration. Women of childbearing age tested negative for serum pregnancy within 7 days before the first dose of the investigational drug.

Exclusion Criteria:

1. Subjects with a history of severe allergies to monoclonal antibodies;
2. Active pia mater lesions or uncontrolled brain metastases exist. Subjects with suspected or confirmed brain metastasis can be enrolled as long as they are asymptomatic and do not require treatment (such as radiotherapy, surgery, or corticosteroid therapy) to control the symptoms of brain metastasis. For subjects with brain metastasis requiring treatment, their symptoms remain stable (without hormone maintenance treatment, without symptoms of brain metastasis) for 2 weeks after treatment, and they can be enrolled.
3. Subjects with active autoimmune diseases or a history of autoimmune diseases, but with the following diseases are allowed to be included in the study: well controlled type I diabetes, well controlled hypothyroidism only requiring hormone replacement treatment, skin diseases without systemic treatment (such as vitiligo, psoriasis or alopecia), or subjects who are expected to have no relapse under the condition of no external trigger factors;
4. Having a history of primary immunodeficiency, a history of allogeneic organ transplantation, or a history of allogeneic hematopoietic stem cell transplantation;
5. Chronic hepatitis B (HBsAg and/or HBcAb positive but HBV DNA\<2000 IU/mL can be included), chronic hepatitis C (HCV antibody positive but HCV RNA negative can be included), and HIV antibody positive;
6. The toxicity of previous anti-tumor treatments has not returned to ≤ Grade 1 (except for alopecia, pigmentation, or other toxicity that the researchers believe is not a safety risk to the subjects);
7. Have a history of serious cardiovascular disease, including but not limited to:

   1. Serious cardiac rhythm or conduction abnormalities, including but not limited to ventricular arrhythmias requiring clinical intervention, third degree atrioventricular block, within 6 months prior to the first dose of the investigational drug;

Uncontrollable serous cavity effusion that requires frequent drainage or medical intervention (such as pleural effusion, abdominal effusion, pericardial effusion, etc., which requires additional intervention within 2 weeks after the intervention, excluding exfoliative cytology testing of the exudate) within 7 days before the first dose of the experimental drug;
9. Severe or active infections (including tuberculosis infections) that require systemic antibacterial, antifungal, or antiviral treatment within 14 days before the first use of the experimental drug, except for subjects with viral hepatitis receiving antiviral treatment;

Inhalation or local application of corticosteroids, adrenal hormone replacement therapy, and short-term (≤ 7 days) use of corticosteroids to prevent contrast agent allergies are allowed.
