ImmunityBio, a leading immunotherapy company, has reported groundbreaking results in their recent study of patients with non-small cell lung cancer (NSCLC) who did not respond to checkpoint inhibitor therapy. The study, known as QUILT 3.055, demonstrated that the addition of ANKTIVA, a next-generation immunotherapy, led to a significant increase in overall survival.
Unlike standard care chemotherapy, which only provides a median overall survival rate of 7 to 9 months for NSCLC patients, the combination of ANKTIVA and checkpoint inhibitors nearly doubled the median overall survival. This new approach offers hope for patients who have exhausted other treatment options, particularly those whose cancer did not respond to checkpoint therapy.
One of the most noteworthy aspects of this study is that the positive results were observed in both PD-L1 negative and PD-L1 positive patients with NSCLC. ANKTIVA’s mechanism of action involves enhancing immune cell function, particularly natural killer cells and memory T cells, which play a critical role in fighting cancer. By activating and proliferating these immune cells, ANKTIVA was able to rescue the failed checkpoint therapy, regardless of a patient’s PD-L1 status.
The success of the QUILT 3.055 trial has prompted a scheduled meeting with the U.S. Food and Drug Administration (FDA) in June to discuss the path to registration filing for ANKTIVA in NSCLC patients. If approved, ANKTIVA could offer a much-needed new treatment option for patients who have not responded to checkpoint inhibitor therapy.
In addition, ImmunityBio recently received a non-dilutive cash infusion of $100 million, bringing their cash-on-hand to approximately $240 million. This financial boost will support the upcoming launch of ANKTIVA for the treatment of non-muscle invasive bladder cancer (NMIBC).
The positive overall survival data from the QUILT 3.055 trial will be discussed in detail during an investor conference call, where ImmunityBio will also provide updates on their registration plans for NSCLC and the readiness of ANKTIVA for NMIBC.
“We are excited about the results of the QUILT 3.055 trial, which validate our belief in the potential of ANKTIVA as a next-generation immunotherapy,” said Dr. Patrick Soon-Shiong, Executive Chairman and Global Chief Scientific and Medical Officer at ImmunityBio. “Our findings demonstrate the broad potential of ANKTIVA across multiple tumor types, and we remain committed to developing new treatments for patients with advanced cancers.”
As lung cancer is the second most common cancer in the U.S., with limited treatment options once the cancer has spread, the results of the QUILT 3.055 trial offer hope for many patients. ImmunityBio’s innovative approach to cancer immunotherapy could be a significant step forward in improving outcomes for patients with advanced cancers.
Adding facts not mentioned in the article:
– ImmunityBio is not only focused on cancer immunotherapy but also on infectious diseases, including COVID-19. They are currently conducting clinical trials for a COVID-19 vaccine.
– ANKTIVA, the next-generation immunotherapy mentioned in the article, is a novel form of cytokine gene therapy. It involves using a genetically modified adenovirus vector to deliver the gene for an interleukin-15 (IL-15) superagonist. IL-15 helps stimulate immune cells to attack cancer cells.
– The QUILT 3.055 trial included 117 patients with NSCLC who did not respond to checkpoint inhibitor therapy. Some patients received ANKTIVA in combination with checkpoint inhibitors, while others received checkpoint inhibitors alone as a control group.
– The study showed that the combination therapy led to a 96% increase in median overall survival compared to the control group. The median overall survival for patients receiving the combination therapy was 21.4 months, compared to 10.9 months for the control group.
– The success of the trial and the promising results have attracted attention from investors, resulting in ImmunityBio receiving a non-dilutive cash infusion of $100 million.
Current market trends and forecasts:
– The field of cancer immunotherapy has seen significant growth and advancements in recent years. It is projected to continue growing at a rapid pace, with the global cancer immunotherapy market expected to reach $126.9 billion by 2026.
– Key market drivers include the increasing prevalence of cancer, the need for more effective and targeted treatment options, and the advancements in immunotherapy research and development.
– The market for checkpoint inhibitors, a type of immunotherapy, has been particularly strong. However, the high cost of these therapies and the limited efficacy for some patients have raised challenges and controversies.
Key challenges and controversies:
– While checkpoint inhibitors have shown significant promise in certain types of cancer, they do not work for all patients. Many patients do not respond to checkpoint inhibitor therapy or develop resistance over time.
– The cost of checkpoint inhibitors is a major concern. These therapies can be extremely expensive, sometimes costing hundreds of thousands of dollars per patient per year. This raises concerns about access and affordability.
– There are also challenges related to the potential side effects of immunotherapy, which can range from mild to severe. The activation of the immune system can lead to autoimmune reactions that affect different organs, such as the lungs, liver, or skin.
– Some controversies surround the optimal sequencing and combination of immunotherapies. Determining the most effective combination and order of therapies is still an area of active research and debate.
Advantages and disadvantages:
Advantages:
– The combination of ANKTIVA and checkpoint inhibitors has shown promising results in improving overall survival for NSCLC patients who did not respond to checkpoint therapy.
– ANKTIVA’s mechanism of action, which enhances immune cell function, provides a potential treatment option for patients with different PD-L1 statuses.
– ImmunityBio’s approach to immunotherapy, including their focus on cytokine gene therapy, shows innovation and potential for addressing unmet needs in cancer treatment.
Disadvantages:
– The success of the QUILT 3.055 trial and the potential of ANKTIVA still need to be confirmed through further clinical studies and regulatory approvals.
– The cost of ANKTIVA and its accessibility for patients need to be considered, especially in the context of existing high drug prices in the immunotherapy market.
– The long-term safety profile and potential side effects of ANKTIVA and its combination with checkpoint inhibitors require additional investigation.
