What You Need to Know Before You Apply

What is the purpose of this trial?

This clinical trial is a prospective, multicenter, open-label, randomized, actively controlled, parallel-group Phase 3 clinical trial to evaluate the efficacy, safety and tolerability of treatment with IMA203 administered at the recommended phase 2 dose versus investigator's choice of treatment in patients with previously treated, unresectable or metastatic cutaneous melanoma.

Do I need to stop my current medications to join the trial?

The trial protocol does not specify if you need to stop taking your current medications. However, you cannot have received systemic corticosteroids within 2 weeks before a certain procedure, or any anti-cancer therapy or radiotherapy within 1 week before starting the trial treatment.

Is IMA203 safe for treating skin cancer?

The treatment imiquimod, which may be related to IMA203, has been used safely in humans for skin conditions like basal cell carcinoma and actinic keratosis. It is generally well-tolerated, though it can cause local skin reactions. ^{1 2 3 4 5}

What data supports the effectiveness of the treatment IMA203 for skin cancer?

Research shows that imiquimod, a component used in similar treatments, has been effective in treating various skin cancers, including basal cell carcinoma and melanoma, by boosting the immune response to fight cancer cells. This suggests that treatments like IMA203, which may involve similar mechanisms, could potentially be effective for skin cancer. ^{3 6 7 8 9}

What Are the Treatments Tested in This Trial?

Interventions

• IMA203

Trial Overview The trial tests IMA203 against the investigator's choice from treatments like chemotherapy drugs paclitaxel plus carboplatin, immunotherapies pembrolizumab or ipilimumab, among others. It's randomized and open-label, meaning patients know which treatment they receive. The goal is to compare effectiveness and safety.

How Is the Trial Designed?

Group I: Experimental arm Experimental Treatment 1 Intervention

Non-myeloablative chemotherapy for lymphodepletion (LD) over 4 days using fludarabine (FLU) and cyclophosphamide (CY), one-time administration of IMA203, and adjunctive therapy with low dose interleukin (IL)-2 for up to 10 days, starting approximately 24 h after IMA203 infusion, optional bridging therapy

Group II: Control arm- investigator's choice Active Control 10 Interventions

Investigator's choice of treatment approved by the respective Competent Authority (nivolumab plus relatlimab \[Opdualag®\], lifileucel, nivolumab, pembrolizumab, ipilimumab, or chemotherapy \[e.g., dacarbazine, temozolomide, paclitaxel, alb-bound paclitaxel, or paclitaxel plus carboplatin\]) as determined by the site investigator in accordance with current respective prescribing information (PI) and/or summary of product characteristics (SmPC), optional bridging therapy.

Published Research Related to This Trial

Imiquimod is an effective TLR7 agonist that modifies the immune response and is currently used to treat actinic keratoses and superficial basal cell carcinoma.

The treatment regimen for superficial basal cell carcinoma involves a 6-week application of imiquimod, providing a non-surgical alternative for patients.

Topically applied MS-275, a histone deacetylase inhibitor, significantly reduced tumor burden in a mouse model of skin cancer, indicating its potential efficacy for treating cutaneous squamous cell carcinomas, especially in immunocompromised patients.

MS-275 was effective in inhibiting the growth of patient-derived cancer cells, particularly those from a metastatic site, suggesting that this treatment could be a targeted option for high-risk cases with reduced systemic side effects.

In a study of 25 stage III-IV melanoma patients treated with a combination of monobenzone and imiquimod for 12 weeks, 38% showed local regression of cutaneous metastases, indicating the treatment's efficacy.

The therapy was well-tolerated and induced systemic immune responses, including melanoma-specific antibodies and CD8+ T-cell responses, suggesting it may enhance the body's overall anti-melanoma immunity.

In a study of 12 patients with periocular melanoma in situ, topical 5% imiquimod cream led to complete histologic clearance of atypical melanocytes in 11 patients after a mean treatment duration of 3.9 months, demonstrating its efficacy as a treatment option.

While most patients experienced mild side effects like redness and discomfort, there were no systemic side effects, indicating that imiquimod cream is a safe local treatment for this type of skin cancer.

Imiquimod applied three times a week for one or two shorter treatment courses resulted in a complete clearance rate of 26.8% after the first course and 53.7% overall, indicating its effectiveness in treating actinic keratosis.

After one year, recurrence rates were 39% for those treated with imiquimod, suggesting that while the treatment is effective, long-term follow-up is necessary due to the possibility of lesions returning.

Vehicle-controlled, double-blind, randomized study of imiquimod 5% cream applied 3 days per week in one or two courses of treatment for actinic keratoses on the head. Jorizzo, J., Dinehart, S., Matheson, R., et al.[2018]

The study developed nanostructured lipid carriers (NLCs) for imiquimod (IMQ), which significantly improved the drug's deposition in deeper skin layers compared to the commercial cream, enhancing its potential efficacy for treating skin conditions.

The optimized IMQ-NLC formulation was incorporated into a matrix-type patch, which not only improved drug delivery but also aimed to be more patient-friendly and environmentally sustainable, addressing common issues with topical treatments.

Tirbanibulin 1% ointment is an effective new treatment for actinic keratosis (AK), showing similar efficacy to established treatments like fluorouracil and photodynamic therapy, with an odds ratio of 11.1 for complete clearance.

The systematic review included 46 studies and confirmed that tirbanibulin has a favorable safety profile and can be applied in a single short treatment period, making it a convenient option for patients compared to traditional therapies.

In a study involving 202 patients (118 with actinic keratosis and 84 with superficial basal cell carcinoma), treatment with imiquimod 5% cream showed no significant negative impact on health-related quality of life (HRQoL) as measured by the Skindex-17 and Skin Cancer Index.

While there was a slight dip in HRQoL at the end of the treatment period, overall, the findings suggest that imiquimod treatment does not lead to clinically relevant changes in patients' quality of life, indicating its safety in this regard.

In a study involving 40 elderly patients (median age 78-79) with nonmelanoma skin cancers (BCC and SCC) who were not candidates for surgery, treatment with imiquimod cream 5% showed promising results, with only 3 out of 45 lesions having residual tumors after therapy.

Imiquimod was found to be safe and well-tolerated, and its use as an adjunctive therapy led to improved tumor control compared to traditional methods like electrodesiccation and curettage, suggesting it may be a suitable noninvasive option for elderly patients.
