    Measured: From Day1 to Day15 after first dose of AP505

  2. AE Assessment

    All AEs and SAEs will be collected, regardless of the relationship to the IP.

    Measured: From screening to follow-up period which includes safety follow-up (30/60/90 days after last dose) and survival follow-up (every 3 months until subject loss to follow-up, death, withdrawal of consent, or study termination, whichever occurs first).

  3. Determine the maximum tolerated dose (MTD)

    Measured: From first dose of AP505 until 28 days after the last dose of AP505

  4. Determine the recommended phase II dose (RP2D)

    Measured: From first dose of AP505 until 28 days after the last dose of AP505

    Measured: From first dose until 7 days after treatment discontinuation/ termination

  5. To characterize the immunogenicity profile of AP505 in patients with advanced solid tumors

    Immunogenicity indicators: the level of anti-drug antibody (ADA).

    Measured: From C1D1 (Cycle 1 is 15 days ; Cycle 2 onwards: each cycle is 28 days), until safety follow up (up to 90 days after the last dose).

  6. To characterize the immunogenicity profile of AP505 in patients with advanced solid tumors

    Immunogenicity indicators: the level of NAb (if ADA is positive).

    Measured: From C1D1 (Cycle 1 is 15 days ; Cycle 2 onwards: each cycle is 28 days), until safety follow up (up to 90 days after the last dose).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AP505 in people with Advanced Solid Tumors, run by AP Biosciences Inc. at 1 site in Taiwan.

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 17 inclusion and 39 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: under way, not looking for participants, as of the sponsor's last update on 9 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. 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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Dose-Escalation : DLT Assessment (time frame: From Day1 to Day15 after first dose of AP505). 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 9 Dec 2024.
