What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new treatment called ADRX-0405 to determine its safety and effectiveness for individuals with certain advanced cancers. The main goal is to identify the highest dose patients can tolerate without serious side effects. The trial targets cancers such as prostate cancer that no longer respond to standard treatments, as well as advanced gastric and lung cancers. Individuals diagnosed with these specific cancers may be suitable candidates for the trial. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.

Will I have to stop taking my current medications?

The trial requires that you stop taking any anticancer or investigational therapy at least 14 days before starting, or 4 weeks for certain prostate cancer treatments. Routine antimicrobial prophylaxis is allowed, but active infection treatments are not.

Is there any evidence suggesting that ADRX-0405 is likely to be safe for humans?

Research has shown that ADRX-0405 appears promising in early lab studies. Animals tolerated it well, with no serious side effects reported. These initial studies suggest the drug is safe and effective against various tumors.

However, studies in humans are still ongoing. Some side effects have emerged during these trials. For instance, ADRX-0405 can decrease white blood cells, which are crucial for the immune system. Researchers continue to study the exact effects on humans.

In this early trial phase, researchers focus on understanding how the drug works in the body and its safety. This phase is crucial for determining the best dose that balances effectiveness and safety. While the treatment shows potential, more information from these human studies will help clarify its safety. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for solid tumors, which often include chemotherapy or targeted therapies, ADRX-0405 is unique because it focuses on a novel mechanism that targets specific tumor pathways. Researchers are excited about this treatment because it aims to selectively attack cancer cells with potentially fewer side effects than traditional chemotherapy. Additionally, ADRX-0405 might overcome resistance issues seen with current therapies, offering new hope for patients whose tumors have stopped responding to existing options.

What evidence suggests that ADRX-0405 might be an effective treatment for solid tumors?

Research has shown that ADRX-0405 is promising in early lab studies, performing well across various tumor types. These studies suggest it might target and treat solid tumors by delivering medicine directly to cancer cells. The treatment has demonstrated favorable absorption and elimination rates in the body. Although human studies provide limited information, early results indicate that ADRX-0405 could help treat advanced solid tumors. This trial includes a Phase 1a Dose Escalation arm to identify the maximum tolerated dose and a Phase 1b Dose Expansion arm to further evaluate its effectiveness in subjects with previously treated mCRPC. More detailed information is expected as ongoing trials continue. ^{1 3 6 7 8}

Published Research Related to This Trial

4-Demethoxydaunorubicin (4-DMDR) was tested in 32 patients with metastatic non-small cell lung cancer, showing only marginal activity with a major response rate of 3.3%, indicating limited efficacy at the studied dose of 40-50 mg/m2 every 21 days.

The most common side effect observed was leukopenia occurring 10-14 days after treatment, suggesting that while 4-DMDR may have less cardiotoxicity than daunorubicin, its overall therapeutic benefit in this patient population is minimal.

In a phase I trial involving 16 adult patients with solid tumors, the new drug 4-demethoxydaunorubicin was found to have a maximum tolerated dose of 18 mg/m2, with myelosuppression, particularly leucopenia, being the main dose-limiting side effect.

The study suggests that a starting dose of 15 mg/m2 every 3-4 weeks is appropriate for future phase II trials, indicating a potential for further investigation into its efficacy and safety in treating solid tumors.

In a study of 13,917 cancer patients, 297 hazardous drug-drug interactions (DDIs) were identified, with proton pump inhibitors (PPIs), dexamethasone, and fluoroquinolones being the most common culprits affecting oral antineoplastic agents (OAAs).

The research highlighted that younger patients, those taking multiple medications, and those on targeted therapies are at a higher risk for these hazardous DDIs, emphasizing the need for careful monitoring by healthcare providers when prescribing OAAs.

Patients with small-cell lung cancer (SCLC) had significantly higher pre-treatment levels of soluble death receptor 5 (sDR5) compared to healthy controls, indicating a potential biomarker for the disease.

Post-treatment levels of sDR5 decreased significantly after first-line chemotherapy and were strongly correlated with treatment responses and overall survival, suggesting that sDR5 could be used to predict patient outcomes in SCLC.

Human osteosarcoma cells developed resistance to adriamycin (ADR) after repeated high-dose exposure, showing cross-resistance to other drugs like methotrexate and vincristine, but also collateral sensitivity to cisplatin.

Combining ADR treatment with verapamil, a calcium antagonist, enhanced the inhibition of growth in ADR-resistant osteosarcoma cells, suggesting a potential strategy to overcome drug resistance.

In a study involving 16 patients with metastatic ovarian cancer, treatment with 4'deoxydoxorubicin at a dose of 30 mg/m2 every 3 weeks resulted in no clinical responses, indicating it is ineffective for this patient group.

The treatment was associated with infrequent toxicities, primarily neutropenia and thrombocytopenia, but overall, the lack of efficacy led to the conclusion that further investigation of 4'deoxydoxorubicin in this context is not warranted.

In a study involving 17 patients with advanced gastric adenocarcinoma, 4'-deoxydoxorubicin (DxDx) showed limited efficacy, with only one patient achieving a partial response lasting 2.5 months.

The treatment was associated with significant side effects, including severe myelosuppression in 69% of patients, leading to dose reductions, and a median survival of only 3.3 months after starting treatment.

In a study of 16 patients with advanced small cell lung cancer, 4-Demethoxydaunorubicin (4-DMDNR) did not lead to complete or partial responses, but 9 patients experienced minor radiographic improvements and 6 reported transient symptomatic relief.

The treatment was generally well-tolerated with mostly minor side effects, and importantly, there was no evidence of cardiotoxicity; however, one patient did experience severe neutropenia leading to septicaemia.

In a phase II study involving 18 patients with non-small cell lung cancer, the oral treatment with 4-demethoxydaunorubicin resulted in significant hematologic toxicity, with eight patients experiencing severe side effects (ECOG grade 3 or 4).

Despite the observed toxicity, there were no responses to the treatment, indicating that 4-demethoxydaunorubicin may not be effective for this patient population.

The treatment was well-tolerated, with mild to moderate hematologic toxicity and no observed cardiac toxicity, making it a safer alternative to traditional doxorubicin, which is known for its higher toxicity.

In a phase I trial involving 51 adults with advanced gastrointestinal solid tumors, 4-demethoxydaunorubicin (4-dm DNR) was safely administered in oral capsules, with no fatal toxicity observed at doses up to 25.0 mg/m2.

However, dose-limiting granulocytopenia and non-hematologic toxicity occurred at doses of 22.5 mg/m2 or higher, and no therapeutic responses were recorded, indicating limited efficacy of the treatment.
