Trial overview
These clinical trials are studying AUTOLOGOUS T-CELLS TRANSDUCED WITH THE LENTIVIRAL LV-R11KEA ENCODING T-CELL RECEPTOR TARGETING PATIENT-SPECIFIC TUMOR-ASSOCIATED ANTIGENS in cancer patients.[1][2] The studies are looking at whether the treatment is safe, tolerable, and active against tumors.[1][2]
One study includes people with solid tumors, which are cancers that form a tumor mass.[1] The other study focuses on previously treated, unresectable or metastatic cutaneous melanoma, a type of skin cancer.[2]
Who can participate
The first trial is for patients with solid tumors.[1] The second trial is for patients with cutaneous melanoma that has already been treated and cannot be removed by surgery or has spread to other parts of the body.[2]
These are study-specific groups, so participation depends on the cancer type and the exact trial rules.[1][2]
Trial phases and design
The solid tumor study is a Phase 1/2 interventional trial.[1] Phase 1 checks early safety and helps find the right dose, while Phase 2 looks more closely at whether the treatment works against cancer.[1]
The melanoma study is a Phase 3 interventional trial.[2] It compares AUTOLOGOUS T-CELLS TRANSDUCED WITH THE LENTIVIRAL LV-R11KEA ENCODING T-CELL RECEPTOR TARGETING PATIENT-SPECIFIC TUMOR-ASSOCIATED ANTIGENS with investigator’s choice of treatment.[2]
The Phase 1/2 study includes IMA203 and IMA203CD8, and it also studies IMA203 with nivolumab in some parts of the trial.[1] The Phase 3 study compares IMA203 against several treatment options chosen by the investigator, such as nivolumab, paclitaxel, temozolomide, pembrolizumab, ipilimumab, dacarbazine, carboplatin, paclitaxel albumin-bound, and Opdualag.[2]
What the trials measure
The first trial measures treatment-emergent adverse events, adverse events of special interest, serious treatment-emergent adverse events, and dose-limiting toxicities in Phase 1.[1] A dose-limiting toxicity is a side effect that may stop the dose from being increased or continued.[1]
In Phase 2 of the first study, the main cancer outcome is objective response rate, which means the number of patients whose tumors shrink or disappear based on scan review using RECIST 1.1.[1] RECIST 1.1 is a standard method for measuring tumor change on scans.[1]
The Phase 3 melanoma trial measures progression-free survival, using a blinded independent central review and RECIST 1.1.[2] This means experts who do not know which treatment was given review the scans to see how long the cancer stays from getting worse.[2]
Important study details
Both studies are listed as Authorised and are interventional trials, which means the researchers assign a treatment and then measure the results.[1][2]
The solid tumor study has an enrollment of 543 patients, and the melanoma study has an enrollment of 384 patients.[1][2] These numbers show that the studies include a relatively large group for testing safety and effectiveness.[1][2]
The brief study goals for the solid tumor trial are to evaluate safety, tolerability, maximum tolerated dose or recommended Phase 2 dose, and anti-tumor activity.[1] The melanoma trial aims to evaluate the efficacy of IMA203 compared with control treatment.[2]
Why these trials matter
These studies are important because they test the treatment in different cancer settings, from broad solid tumors to advanced melanoma.[1][2] They also use different trial phases, which helps researchers learn first about safety and later about how well the treatment may work compared with other options.[1][2]
For patients, the key question in these trials is whether AUTOLOGOUS T-CELLS TRANSDUCED WITH THE LENTIVIRAL LV-R11KEA ENCODING T-CELL RECEPTOR TARGETING PATIENT-SPECIFIC TUMOR-ASSOCIATED ANTIGENS can help control cancer while remaining safe enough to study further.[1][2]
