Trial overview
The main study of Art6043 is Phase 1/2 and is listed as authorised.[1] It is an interventional study, which means the researchers give a treatment and then measure what happens.[1]
This trial is studying people with advanced solid tumors and metastatic solid tumors.[1] The study also includes a breast cancer part for patients with HER2-negative locally advanced or metastatic breast cancer with a gBRCA mutation.[1]
The planned enrollment is 120 people.[1]
Who can participate
The trial includes adults with advanced or metastatic solid tumors in Part A.[1] In simple words, this means cancers that are no longer early stage and may have spread.[1]
Part B2 is for patients with HER2-negative locally advanced or metastatic breast cancer who also have a gBRCA mutation.[1] This is a more specific group, so the study can look at whether Art6043 may have early signs of benefit in that population.[1]
What the study measures
In Part A, the main safety measure is the incidence of dose-limiting toxicities, often called DLTs.[1] DLTs are side effects serious enough to limit how much treatment can be given.[1]
Part A also measures the incidence and severity of adverse events using CTCAE v5.0.[1] Adverse events are any unwanted medical problems seen during the study, and severity means how mild or serious they are.[1]
In Part B2, the main efficacy measure is progression-free survival (PFS) based on RECIST v1.1.[1] PFS is the time during which the cancer does not get worse, and RECIST v1.1 is a standard way to measure tumor changes on scans.[1]
Study design and treatment groups
The study tests Art6043 orally, meaning it is taken by mouth.[1] The trial also includes olaparib, listed in the source as Lynparza, in some treatment groups.[1]
According to the trial summary, Part A is designed to find the maximum tolerated dose (MTD) and/or the recommended Phase 2 dose (RP2D) of Art6043, both as a single treatment and in combination with olaparib.[1] The MTD is the highest dose people can take without too many serious side effects, and the RP2D is the dose chosen for later testing.[1]
Part B2 compares Art6043 plus olaparib with olaparib alone in the breast cancer group to look for early signs that the combination may work better.[1]
Why this trial matters for patients
This trial is mainly an early research study, so its first job is to learn about safety and dose, not to prove long-term benefit.[1] That is why the trial focuses on DLTs, adverse events, and dose selection in Part A.[1]
For patients with HER2-negative breast cancer and a gBRCA mutation, the study also asks whether the combination approach may delay cancer growth compared with olaparib alone.[1] This helps researchers decide whether Art6043 should be studied further in larger trials.[1]
