About this study

Official title: An Open-Label, Non-randomized, Multi-center Phase I Study Evaluating the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of Bi-Ligand-Drug Conjugate CBP-1018 in Patients With Advanced Solid Tumors

This is an open-label, non-randomized, multi-center, phase I study of bi-ligand-drug conjugate CBP-1018 in patients with advanced solid tumors. This study will be conducted in 2 parts: Part A (Dose Escalation) and Part B (Dose Expansion). Both parts include screening period, treatment period, end of treatment (EOT)/withdrawal, safety follow-up (SFU) and long-term-follow-up (LTFU). CBP-1018 will be administrated on eligible subjects until disease progression, unacceptable toxicity, withdrawal of consent or Sponsor's decision to stop the study, etc.

Read the detailed description

Part A (Dose Escalation) is to evaluate the safety, tolerability, PK and preliminary efficacy of CBP-1018 and determine the MTD and RP2D of CBP-1018 administrated iv Q2W (4 weeks/cycle), utilizing accelerated titration at lower doses (0.03 mg/kg and 0.06 mg/kg) and an i3+3 design at following doses (0.08 mg/kg,0.10 mg/kg,0.12 mg/kg and 0.14mg/kg, etc.), respectively. The DLT evaluation period will be 28 days from the first dose of CBP-1018. Up to 2 subjects will be allowed under DLT evaluation period at the same time. The interval between the first treatment of CBP-1018 to the 2 subjects under DLT evaluation period at the same time, is at least 1 week. Safety monitoring committee (SMC), comprised of Investigators and sponsor's medical personnel, etc., will be responsible for safety monitoring, dose escalation safety review and justification, MTD/RP2D determination, and other critical study decisions. A higher dose level may be added on the decision of SMC, if MTD is not observed at 0.14mg/kg. Intermediate dose levels among planned dose levels may also be added by SMC for further exploration. RP2D may be the same dose level as MTD or lower than it. Up to 10 additional subjects will be enrolled in one or more dose levels that have been shown to be safe and tolerable to better estimate the RP2D and better characterize the safety, efficacy, and pharmacodynamics for CBP-1018. Different schedules (QW or Q3W, for example) may be explored in Part A, according to emerging clinical and PK data, either.

Part B (Dose Expansion) is to further evaluate the efficacy and safety profile of CBP-1018 in 4 tumor-specific cohorts:

  • Cohort 1 (Metastatic castration resistant prostate cancer, mCRPC);Cohort 2(Advanced renal cell cancer, RCC); Cohort 3 (Advanced lung cancer, LC); Cohort 4 (Other advanced solid tumors).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CBP-1018 in people with Solid Tumor, run by Coherent Biopharma (Suzhou) Co., 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 20 inclusion and 18 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: status not confirmed, as of the sponsor's last update on 28 Aug 2024. 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?

Results are not available in the source record.

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

Contact Jiangang Yu, Ph D (0512-85550899 ext. 8010, jiangang.yu@coherentbio.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence and severity of Adverse Events (AEs) in Part A (time frame: 12 months). The study lists 4 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 28 Aug 2024.
