AML Treatment Breakthrough: Could Breast Cancer Drugs Hold the Key?

Acute myeloid leukemia (AML), a rapidly progressing cancer of the blood and bone marrow, affects over 20,000 Americans annually. While the introduction of venetoclax in 2019, combined with azacitidine, offered a significant step forward in treatment, the development of drug resistance remains a major hurdle. Now, groundbreaking research from Oregon Health & Science University (OHSU) suggests an unexpected ally in the fight against AML: drugs originally developed for breast cancer.

The Venetoclax Resistance Problem

Venetoclax works by targeting a protein that helps leukemia cells survive. However, AML cells are remarkably adaptable. As the National Cancer Institute explains, they often find ways to circumvent the drug’s effects, leading to relapse. “Unfortunately, almost everyone will eventually have drug resistance,” notes Dr. Jeffrey Tyner of OHSU, a co-leader of the Beat AML 1.0 program. Current five-year survival rates hover between 25% and 40%, highlighting the urgent need for new strategies.

Palbociclib: An Unexpected Weapon

The OHSU team, led by Dr. Melissa Stewart, screened over 25 drug combinations and discovered that pairing venetoclax with palbociclib – a CDK4/6 inhibitor used to treat certain types of breast cancer – yielded the most promising results. Published in Cell Reports Medicine, the study revealed that palbociclib effectively blocks the AML cells’ ability to adapt and survive when faced with venetoclax. Essentially, it disrupts the protein production machinery within the cells.

Did you know? CDK4/6 inhibitors like palbociclib work by preventing cells from progressing through the cell cycle, effectively halting their growth and division. This mechanism, successful in breast cancer, appears to have a similar impact on AML cells.

How the Combination Works: Shutting Down Survival Pathways

The research pinpointed a key mechanism: AML cells exposed to venetoclax alone ramp up protein production as a survival tactic. Palbociclib intercepts this process, preventing the cells from compensating for the effects of venetoclax. Genome-wide CRISPR screening further demonstrated that the combination doesn’t rely on the same vulnerabilities as venetoclax alone, suggesting a synergistic effect – the drugs work together to target multiple survival pathways.

Promising Results in Mouse Models

Testing the combination in mouse models implanted with human AML cells carrying venetoclax-resistant mutations showed dramatic improvements. While venetoclax alone offered no survival benefit in these models, the combination therapy extended survival to 11-12 months in the majority of mice. Remarkably, one mouse remained alive even after the study concluded. These findings offer a strong preclinical rationale for clinical trials.

Beyond Palbociclib: Expanding the Horizon

The OHSU team isn’t stopping at palbociclib. They are now exploring other drugs similar to palbociclib, many of which are also approved for breast cancer, to identify additional potential combination therapies. This approach highlights a growing trend in cancer research: repurposing existing drugs for new indications. The FDA actively encourages drug repurposing as a faster and more cost-effective way to bring new treatments to patients.

The Beat AML Initiative and Data-Driven Discovery

This breakthrough is a direct result of the national Beat AML 1.0 program, a collaborative effort to accelerate AML research. Dr. Tyner emphasizes that the combination was initially identified through Beat AML data, and Dr. Stewart’s research validated the prediction, demonstrating both its efficacy and the underlying mechanisms. This underscores the power of large-scale data analysis and collaborative research in driving innovation.

Future Trends in AML Treatment

Personalized Medicine and Genomic Profiling

The future of AML treatment is increasingly focused on personalized medicine. Genomic profiling of AML cells will become standard practice, allowing doctors to tailor treatment regimens based on the specific mutations driving each patient’s cancer. This will likely involve identifying which patients are most likely to benefit from venetoclax-palbociclib or other combination therapies.

The Rise of Immunotherapies

While chemotherapy and targeted therapies remain crucial, immunotherapies – treatments that harness the power of the immune system to fight cancer – are gaining momentum. Cancer Research UK highlights the growing success of immunotherapies in various cancers. Combining immunotherapies with targeted therapies like venetoclax and palbociclib could offer even more potent treatment options.

Liquid Biopsies for Early Detection and Monitoring

Liquid biopsies, which analyze circulating tumor DNA (ctDNA) in the blood, are revolutionizing cancer detection and monitoring. These non-invasive tests can detect minimal residual disease (MRD) – small amounts of cancer cells that remain after treatment – and predict relapse. Liquid biopsies will likely play a key role in monitoring patients treated with venetoclax-palbociclib and adjusting treatment accordingly.

Pro Tip:

Stay informed about clinical trials. Participating in a clinical trial can provide access to cutting-edge treatments and contribute to advancing cancer research. Resources like ClinicalTrials.gov list ongoing trials worldwide.

Understanding the Challenge: High-Risk AML Subtypes

AML, a cancer of the blood and bone marrow, presents unique challenges based on its genetic makeup. Certain subtypes, particularly those with KMT2A rearrangements (KMT2Ar) and NPM1 mutations (NPM1m), are associated with a high risk of relapse and unfavorable prognosis. These patients often have limited treatment options, underscoring the urgent need for innovative therapies.

Menin inhibitors, like revumenib, represent a new class of targeted agents designed to address these specific genetic vulnerabilities. These medications work by blocking the interaction between the menin protein and the KMT2A protein, which is crucial for cancer cell growth. For patients, this can mean a significant difference in outcomes. The data presented at the European Hematology Association Congress (EHA) is very important for understanding future trends.

Promising Results: Revumenib in Action

The phase 2 AUGMENT-101 study evaluating revumenib in R/R AML patients has yielded impressive results. In patients with NPM1m AML, the complete response (CR) plus complete response with partial hematologic recovery (CRh) rate was 26%. The overall response rate reached nearly 50%. Moreover, the median time to first CR/CRh was a mere 2.8 months.

In the same study focused on patients with KMT2Ar acute leukemia, the CR + CRh rate was 22.7%. The median duration of response for these patients was 6.4 months. What’s more, 34% of these patients went on to receive hematopoietic stem cell transplantation (HSCT). Impressively, of those achieving CR + CRh, 61.1% achieved negative minimal residual disease (MRD) status, a critical indicator of successful treatment. This data is changing perspectives on AML.

Did you know? Minimal residual disease (MRD) refers to the small number of leukemia cells that remain in the body after treatment. Achieving MRD negativity is often associated with a better prognosis and reduced risk of relapse.

Efficacy in NUP98r AML

The AUGMENT-101 phase 1 study also looked at revumenib in 5 patients with NUP98r AML. Responses were observed at certain dosages, with 3 patients achieving morphological remission and 1 achieving MRD negativity before proceeding to HSCT. While the patient group was small, this data further expands the potential of revumenib in treating AML subtypes.

Safety Profile: A Key Consideration

One of the most encouraging aspects of revumenib is its favorable safety profile. Throughout the studies, no new safety signals have emerged, making it a well-tolerated option for patients, especially those who may have already undergone multiple rounds of chemotherapy.
