About this study

Official title: A Multi-center, Open-label, Phase 1/2a Trial to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of KAT-101 in Subjects With HCC

NLP-KAT-101 is a Phase 1/2a dose escalation and expansion study to investigate the safety, tolerability, PK, and preliminary efficacy of oral + intratumoral (IT) KAT in subjects with HCC.

Read the detailed description

Phase 1 will identify the optimal dose for oral alone, IT alone and the recommended Phase 2 dose (RP2D) dose for oral + IT together. Once the RP2D is identified, additional subjects will be enrolled into Phase 2a (dose-expansion) to further investigate the efficacy and safety of oral + IT KAT at the RP2D.

Being tested
KAT-101, KAT-201
Medical subject headings
Carcinoma, Hepatocellular, Fibrolamellar hepatocellular carcinoma

Study groups in NCT05603572
Study groupRoleWhat they receive
Oral experimental armExperimentalOral administration (KAT-101) taken once per day for 4 consecutive days out of 7 (4 days on / 3 days off weekly). Each cycle is 28 days. Treatment will continue for up to 12 cycles until progressive disease (PD), unacceptable toxicity, or any reason for discontinuing its administration, whichever occurs first.
Receives: Drug: KAT-101
IT experimental armExperimentalIT administration (KAT-201) will be injected via percutaneous IT injection with ultrasound and/or computed tomography (CT) guidance once a week (on Day 1 weekly). Each cycle is 28 days. Treatment will continue for up to 2 cycles until PD, unacceptable toxicity, or any reason for discontinuing its administration, whichever occurs first.
Receives: Drug: KAT-201
Oral + IT experimental armExperimentalOnce optimal oral and IT dose are determined, oral + IT will be administered as follows: oral administration (KAT-101) will be taken once per day for 4 consecutive days out of 7 (4 days on / 3 days off weekly). Treatment will continue for up to 12 cycles (each cycle 28 days). IT administration (KAT-201) will be injected via percutaneous IT injection with ultrasound and/or CT guidance once a week (on Day 1 weekly). Treatment will continue for up to 2 cycles (each cycle 28 days) until PD, unacceptable toxicity, or any reason for discontinuing its administration, whichever occurs first.
Receives: Drug: KAT-101; Drug: KAT-201

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To determine the Recommended Phase 2 Dose (RP2D) for oral + IT administration

    RP2D is defined as the dose at which dose escalation (oral + IT) ceases

    Measured: 24 months

Secondary outcomes (6)
  1. To evaluate the safety and tolerability of KAT (oral, IT, and oral + IT) in subjects with HCC

    Measured as the number of AEs per CTCAE and changes in laboratory values compared to baseline.

    Measured: 54 months

  2. To evaluate the preliminary anti-tumor activity of KAT for oral + IT administration

    Overall response rate (ORR) is defined as the proportion of subjects with a best overall response (BOR) by Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) and/or mRECIST; disease control rate (DCR), defined as the proportion of subjects with a BOR of CR, PR, or stable disease (SD); duration of response (DOR), defined as the length of time from the time of response (CR or PR) to the time of PD or death; progression-free survival (PFS), defined as the time from the date of treatment initiation to PD or death; overall survival (OS), defined as the length of time from the date of treatment initiation to death from any cause.

    Measured: 54 months

  3. To assess maximum concentration (Cmax) of KAT (oral and oral + IT)

    Blood samples will be drawn to determine Cmax of KAT

    Measured: 54 months

  4. To assess median time to the maximum drug concentration (Tmax) of KAT (oral and oral + IT)

    Blood samples will be drawn to determine Tmax of KAT

    Measured: 54 months

  5. To assess half lives (T1/2) of KAT (oral and oral + IT)

    Blood samples will be drawn to determine T1/2 of KAT

    Measured: 54 months

  6. To assess area under the curve (AUC) of KAT (oral and oral + IT)

    Blood samples will be drawn to determine AUC of KAT

    Measured: 54 months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing KAT-101 and KAT-201 in people with Hepatocellular Carcinoma and Fibrolamellar Carcinoma, run by Primocure Pharma at 1 site in South Korea.

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 5 inclusion and 20 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: stopped early, as of the sponsor's last update on 27 Oct 2026. 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 South Korea. 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

The study was stopped early (reason given: discontinued enrollment). Results are not available in the source record.

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?

To determine the Recommended Phase 2 Dose (RP2D) for oral + IT administration (time frame: 24 months). 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 27 Oct 2026.
