What is the purpose of this trial?

This trial tests the safety and effectiveness of a new treatment called DCSZ11 for individuals with advanced or spreading solid tumors. It examines how DCSZ11 works alone and with pembrolizumab to assess its potential in fighting cancer. The trial includes various parts to determine the optimal dose and combination with standard treatments like doxorubicin for soft tissue sarcoma and tebentafusp for uveal melanoma. Individuals with advanced cancer unresponsive to standard treatments might be suitable for this trial. Participants should have a tumor that can be biopsied and meet other specific health criteria. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the chance to be among the first to receive this new treatment.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, you cannot have received systemic anticancer treatments or investigational products within 14 days before the first dose of the study drug.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that DCSZ11, whether used alone or with pembrolizumab, remains in the early testing stages, so limited safety information is available. Previous patients have demonstrated that pembrolizumab is generally safe for treating advanced cancers, though it can cause side effects like tiredness or skin problems.

Since DCSZ11 is being tested in a Phase 1 trial, the main goal is to assess its safety and determine the right dose. Researchers are just beginning to evaluate how well people can tolerate it. Current studies are crucial for understanding more about DCSZ11’s safety, especially when combined with other treatments. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about DCSZ11 because it represents a novel approach to treating advanced cancers, which traditionally rely on chemotherapy, radiation, or surgery. Unlike these standard treatments, DCSZ11 is being tested in combination with pembrolizumab, an immunotherapy drug that helps the immune system target cancer cells more effectively. This combination has the potential to enhance the body's natural defenses against cancer, offering a promising new avenue for patients with limited options. Additionally, DCSZ11 is being explored in different dosing strategies and combinations, such as with doxorubicin for soft tissue sarcoma and tebentafusp for uveal melanoma, which could lead to more personalized and effective treatment regimens.

What evidence suggests that this trial's treatments could be effective for advanced cancer?

Research has shown that pembrolizumab can effectively shrink tumors and extend the lives of people with various advanced cancers. It has been particularly successful in treating non-small-cell lung cancer and other tumors with specific markers. In this trial, researchers are testing a new drug, DCSZ11, to determine if it can enhance these effects when combined with pembrolizumab for advanced or spreading solid tumors. DCSZ11 is an anti-CD93 monoclonal antibody that targets a protein involved in tumor growth and spread. Participants in this trial may receive either the combination of DCSZ11 and pembrolizumab or DCSZ11 alone, as researchers assess the safety and effectiveness of these treatments in combating advanced cancers. ^{1 2 3 5 6}

Trial Overview

The trial is testing DCSZ11 alone and combined with Pembrolizumab in patients with various types of solid tumors that haven't responded to standard therapies. It's an early-phase study looking at how well these drugs work together for treating cancer.

How Is the Trial Designed?

Group I: Phase 1b Standard of Care Experimental Treatment 2 Interventions

Phase 1b - Standard-of-Care (SOC) Combinations Safety Lead-in/ Expansion in Select Indications A safety lead-in using the BOIN design followed by a Simon two-stage like design will be used to evaluate DCSZ11 in combination with standard of care in select indications. Patients will receive DCSZ11 IV at one of the dose escalation dose levels/schedule (or dose/schedule selected for optimization/expansion). Once the safety lead-in is completed, a Bayesian continuous toxicity monitoring will be used to monitor for unacceptable toxicity in expansions. The following SOC combination expansion cohorts will be enrolled: * 1b SOC Cohort 1: Doxorubicin combination in soft tissue sarcoma * 1b SOC Cohort 2: Tebentafusp combination in uveal melanoma

Group II: Phase 1b Dose Expansions Experimental Treatment 2 Interventions

Dose expansion to further investigate the safety, tolerability, and preliminary evidence of antitumor activity of the combination with pembrolizumab in select tumor indications.

Group III: Phase 1a Dose Escalation Monotherapy Experimental Treatment 1 Intervention

Dose escalation to investigate the safety and tolerability of DCSZ11.

Group IV: Phase 1a Dose Escalation Combination Experimental Treatment 2 Interventions

Dose escalation to investigate safety and tolerability, and determine DCSZ11 Phase 1b doses in combination with pembrolizumab.
