AMXT 1501 + DFMO for Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores a new cancer treatment combining two drugs, AMXT 1501 and DFMO (also known as Eflornithine), to determine safe dosage levels and assess initial anti-cancer effects. The study targets individuals with advanced solid tumors that standard methods cannot treat or have resisted previous treatments. This includes specific cancers such as breast, ovarian, and lung cancers, among others. Eligible participants are those with these advanced cancers who have seen their current therapies fail and are willing to try a new treatment approach. As a Phase 1 trial, participants will be among the first to receive this new treatment, aiding researchers in understanding its effects in people.
Will I have to stop taking my current medications?
The trial protocol does not specify if you need to stop taking your current medications. However, certain medications like enzyme-inducing anticonvulsants and high doses of biotin are not allowed. It's best to discuss your specific medications with the trial team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that the combination of AMXT 1501 and DFMO is safe and well-tolerated in patients with advanced cancer. Studies found that this treatment did not cause unexpected side effects, and patients managed it without serious issues. This suggests it could be a safe option for those considering participation in a clinical trial. However, as with any trial, there is always a chance of side effects, so discussing any concerns with a doctor is important.12345
Why are researchers excited about this trial's treatments?
Researchers are excited about AMXT1501 + DFMO because they represent a novel approach to cancer treatment. Unlike most current treatments that target cancer cells directly with chemotherapy or radiation, this combination aims to disrupt the cellular processes that cancer cells rely on for growth. AMXT1501 works by blocking specific transport mechanisms within the cancer cells, while DFMO inhibits a key enzyme necessary for cell division. This dual action could potentially lead to more effective treatment outcomes with fewer side effects compared to traditional therapies.
What evidence suggests that this trial's treatments could be effective for cancer?
Research has shown that the combination of AMXT 1501 and DFMO affects polyamine metabolism, crucial for the growth and survival of neuroblastoma and other cancers. Animal studies demonstrated that this combination can significantly slow tumor growth. The FDA granted this combination "orphan drug" status, highlighting its potential to improve neuroblastoma treatment. In this trial, participants will join either the Escalation arm, involving dose escalation of DFMO with a fixed dose of AMXT 1501, or the Expansion arm, which will further characterize safety and early anti-tumor activity at the proposed RP2D level. Early trials focused on ensuring the safety and tolerability of this combination in patients with advanced cancer, laying the groundwork for further research into its effectiveness.13678

Are You a Good Fit for This Trial?
This trial is for patients aged 12 and older, weighing over 40 kg, with various advanced solid tumors where standard treatments have failed or are not available. Participants must be able to take oral medication, use an at-home infusion pump, provide a CSF sample and tumor tissue biopsy, and agree to contraception use. Exclusions include recent cancer treatment within the last 4-6 weeks, uncontrolled seizures in DIPG/DMG patients, significant cardiovascular disease within the past 6 months, active liver disease or infections like HIV.Inclusion Criteria

- DFMO
Trial Overview
The study tests AMXT 1501 dicaprate combined with IV DFMO on safety and optimal dosing levels in cancer patients. It's a Phase 1B/2A trial focusing on those with unresectable or metastatic solid tumors including ovarian cancer and gliomas among others.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
The expansion cohort will include up to 40 evaluable patients at a proposed RP2D level of AMXT1501 and DFMO defined by AMXT1501-101A study to further characterize safety at proposed RP2D dose level with repeat dosing, and characterize early anti-tumor activity.
Dose escalation of DFMO with AMXT1501 fixed dose will follow a 3 + 3 dose escalation design. The AMXT 1501 starting dose administered in the first cohort will be 1200mg total daily dose (200 mg capsules; 3 capsules in morning; 3 capsules in evening) along with IV DFMO administered in continuous infusion at 2mL/hr over a 28 days per cycle. The patient can be treated for additional 28 day treatment cycles as deemed appropriate by their study investigator. Dose escalation of DFMO alone will increase per cohort.
