OncLive: Why is ongoing research regarding RAS inhibition imperative for the management of pancreatic cancer?
Smaglo: The understanding of RAS mutations in pancreatic cancer has progressed significantly over the years. Initially labeled as “undruggable,” the urgency to identify effective therapies targeting RAS mutations has not diminished, as these alterations are prevalent in approximately 80% to 90% of pancreatic cancer cases. This prevalence suggests that most patients might qualify for targeted treatment if we can ascertain their specific mutation statuses and advance the development of therapies focused on RAS.
The RAS inhibition area has remained a priority in research efforts. However, in recent years, clinical trials highlighting novel agents that significantly inhibit RAS have emerged. This offers newfound hope for patients dealing with a disease historically treated with chemotherapy alone.
Considering the success of targeted therapies for different targets in other tumor types, what has been the biggest challenge in developing RAS inhibitors?
Development challenges have included identifying drugs capable of effectively targeting RAS alterations across various pathways. The goal has been to inhibit these alterations meaningfully and address the complexity of an individual’s cancer, particularly given that there is substantial heterogeneity concerning RAS status within tumors, necessitating a broader approach to treatment.
The difficulty has been compounded by the need for a drug that can effectively reach and act on the pathway to elicit a therapeutic effect across the diverse RAS alterations within a cancer population.
For novel RAS inhibitors under development, what differentiates them from prior agents? How has this class of drugs evolved?
A significant advancement in the field is the recognition that not all KRAS mutations are alike, prompting discussions centered around the precise biochemistry of individual patient mutations. Understanding the specific mutation and its location within the protein structure is now crucial in determining appropriate drug therapies.
Historically, the focus has been predominantly on targeting specific mutations. The highlighted success story thus far has been the targeting of KRAS G12C mutations, which, albeit effective for a small subset of patients (approximately 2% to 3% of pancreatic cases), emphasizes a need for broader strategies as other mutations remain prevalent within the patient population.
Research indicates that targeting multiple forms of KRAS mutations simultaneously, through the development of pan-RAS inhibitors, may yield improved results compared to solely focusing on a limited number of specific mutations.
Within the RAS inhibitor space, what is current research focusing on?
Current research predominantly explores innovative agents within later-line therapy regimes for metastatic pancreatic cancer, following initial chemotherapy. For many patients, this entails a sequencing of treatments using fluorouracil-based or gemcitabine-based combinations.
The encouraging outcomes from late-line trials have sparked interest in evaluating the feasibility of incorporating RAS inhibitors earlier in treatment schedules. This includes considerations for integration into first- or second-line therapies or their application as maintenance therapies post-chemotherapy.
Given the heterogeneity of RAS alterations and the presence of other alterations in pancreatic cancer, what is the importance of molecular testing to identify the specific genetic components of a patient’s disease?
It is critical for individuals with pancreatic cancer to undergo next-generation sequencing soon after diagnosis. While the immediate focus is often on KRAS status, acquiring this genetic information promptly can be beneficial as clinical trial options continue to expand, allowing for more targeted therapeutic interventions down the line.
The significance of early molecular testing cannot be overstated, as ongoing research continues to evolve rapidly, presenting new treatment avenues that may emerge as viable options in subsequent therapeutic lines.
What are the challenges in diagnosing pancreatic cancer before it reaches an advanced stage?
One significant hurdle in diagnosing pancreatic cancer early is that localized forms of this disease often present with few or no symptoms. By the time noticeable symptoms appear, the cancer is frequently more advanced.
Innovative research involving circulating tumor DNA holds promise for early detection of pancreatic cancer. An effective approach would allow primary care physicians to order simple blood tests to screen for potential cancers, subsequently leading to further diagnostic evaluations.
Survival outcomes for pancreatic cancer remain starkly lower than those of other cancers diagnosed at analogous stages. Thus, early detection coupled with comprehensive post-operative therapies is essential to enhancing patient outcomes.
Outside of the RAS pathway, what other potential therapeutic approaches currently being investigated could provide additional treatment options for this patient population?
Research into immunotherapy for pancreatic cancer has generated significant interest, with numerous trials exploring methods to modify the tumor environment to enhance immune system recognition of the cancer. Researchers are optimistic about utilizing these insights in developing effective combination strategies with immune checkpoint inhibitors.
Trials investigating cellular therapies, including CAR T-cell modifications and vaccine approaches, are also underway, drawing attention to the potential power of an enhanced immune response against pancreatic cancer.
In honor of Pancreatic Cancer Awareness Month, what would be your message for colleagues about the ongoing research in this space?
Smaglo conveys a message of optimism to his colleagues amid ongoing research in this critical area. Despite the historically disheartening nature of pancreatic cancer outcomes, advancements in RAS inhibitors and other therapeutic strategies are igniting a renewed sense of hope.
Reflecting on successes in other cancer types, such as melanoma’s breakthroughs with immunotherapy, Smaglo believes that the field is on the cusp of significant advancements, potentially leading to more favorable long-term outcomes for those affected by pancreatic cancer.
