Who may be able to join

  • Understand and sign the informed consent form voluntarily.
  • ≥18 years old when signing the informed consent, regardless of sex.
  • Have histologically or cytologically confirmed unresectable advanced, recurrent, or metastatic solid tumors (including but not limited to small cell lung cancer, glioblastoma, urothelial carcinoma, endometrial cancer, cervical cancer, ovarian cancer, breast cancer, and liver cancer) for which standard therapy has failed or was intolerable, and currently no standard treatment is available.

  • For glioblastoma: at least one measurable intracranial tumor lesion according to the RANO 2.0 criteria. For other solid tumors: at least one measurable lesion according to RECIST v1.1 criteria. Note: Target lesions can be located in previously irradiated areas, but must be confirmed by imaging to show disease progression after radiation.
  • For glioblastoma: KPS score ≥60. For other solid tumors: ECOG performance status of 0 or 1.
  • Meet the following laboratory criteria (without receiving any blood products, hematopoietic growth factors, albumin, or other treatments within 14 days prior to testing, except iron supplements):
  • Hematology: Hemoglobin (Hb) ≥100 g/L, absolute neutrophil count (ANC) ≥1.5×10^9/L, platelet (PLT) count ≥100×10^9/L.
  • Biochemistry: 1) Dose escalation phase: Serum creatinine (Cr) ≤ upper limit of normal (ULN); total bilirubin (TBIL) ≤1.25×ULN; alanine aminotransferase (ALT), aspartate aminotransferase (AST) ≤1.5×ULN (for subjects with liver metastases or hepatocellular carcinoma: ≤3×ULN). 2) Cohort expansion phase: Cr ≤1.5×ULN; TBIL ≤1.5×ULN; ALT, AST ≤2.5×ULN (for subjects with liver metastases or hepatocellular carcinoma: ≤5×ULN).
  • Coagulation: International normalized ratio (INR) ≤1.5×ULN; prothrombin time (PT) and activated partial thromboplastin time (APTT) ≤1.5×ULN (for participants receiving prophylactic anticoagulation, the INR and APTT should be within a safe and effective therapeutic range as judged by the investigator).
  • Urinalysis: Urine protein <2+; if ≥2+, a 24-hour urine protein quantification should be performed. <1 g/24 h can be enrolled but ≥1 g/24 h is prohibited. without quantification when urine protein ≥2+ is not allowed.
  • Expected survival ≥12 weeks.
  • Cohort Expansion Phase: 1) Cohort 1: Histologically or cytologically confirmed small cell lung cancer (SCLC) that has progressed or recurred after at least two lines of systemic chemotherapy (including a platinum-based regimen). Note: A new line of treatment is defined as a change in treatment due to disease progression, not due to toxicity or other reasons. Re-initiation of the same treatment regimen after initial progression is considered a new line of treatment. 2) Cohort 2: Recurrent or progressive glioblastoma confirmed by histopathology or imaging, which has progressed or recurred after at least one prior treatment with temozolomide.

About this study

Official title: A Phase 1 Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of CS231295 in Subjects With Advanced Solid Tumors

This trial is a single-arm, open-label, first-in-human study of CS231295, comprising two phases: dose escalation (including single-dose and multiple-dose) and cohort expansion. The Dose-Limiting Toxicity (DLT) observation period includes 6 days for single-dose and the first cycle (28 days) for multiple-dose. The overall study consists of screening period, treatment period, and follow-up period.

The primary objectives of this study are to evaluate the safety, tolerability and pharmacokinetic (PK) characteristics of CS231295 in patients with advanced solid tumors, and to recommended Phase 2 dose(s) (RP2D) of CS231295 in appropriate tumor(s).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CS231295 in people with Neoplasms and Glioblastoma, Adult, run by Chipscreen Biosciences, Ltd. at 2 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 38 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 25 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Xinhang Wang (+86 0755-36993500 ext. 3550, xinhwang@chipscreen.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

incidence of dose-limiting toxicity (DLT) (time frame: 34 days after, that is 6 days after single-dose and 28 days after first administration in multiple-dose). The study lists 11 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 May 2025; AzTrials last refreshed its copy on 8 Nov 2026.
