"We are delighted to have received the Rare Pediatric Disease Designation for Controlled IL-12 from the FDA. This milestone for Ziopharm emphasizes the significant unmet need for children living with DIPG," said Laurence Cooper, M.D., Ph.D., Chief Executive Officer of Ziopharm. "Currently, there are no viable treatment options for this type of brain tumor. We are working with the FDA to advance Controlled IL-12 as a new gene therapy for this aggressive disease, which has historically been largely seen as incurable."

The FDA grants Rare Pediatric Disease Designation for serious and life-threatening diseases that primarily affect children ages 18 years or younger and fewer than 200,000 people in the United States. If Ziopharm’s Biologics License Application (BLA) for Controlled IL-12 in DIPG is approved, the Company may be eligible to receive a priority review voucher from the FDA, which can be redeemed to obtain priority review for any subsequent marketing application or may be sold or transferred to another company for their program.

About DIPG
In children, the incidence of brain cancer is approximately 4.84 per 100,000, according to the National Cancer Institute. Glioma in the pontine region of the brain, or DIPG, accounts for approximately 10-15 percent of all cases of pediatric brain tumors, with about 150-300 new diagnoses per year in the United States.1 Median survival ranges from 8-11 months.2 There are no curative options.

About Controlled IL-12 (Ad-RTS-hIL-12 plus veledimex)
Ziopharm’s Controlled IL-12 platform is an investigational gene therapy designed to induce and control the production of human interleukin 12 (hIL-12), a master-regulator of the immune system. The Company has treated more than 175 patients, including more than 125 patients with rGBM, with Ad-RTS-hIL-12 plus veledimex and administered more than 1,300 doses of veledimex across three types of solid tumors, building a significant safety profile, mechanistic dataset and evidence of anti-tumor effects.

Controlled IL-12 is being studied in a phase 1/2 trial (NCT03330197) designed to evaluate the safety and tolerability of a single intratumoral injection of Ad-RTS-hIL-12 given with up to 14 days of oral veledimex in children with gliomas. Up to 12 patients with DIPG may be enrolled in phase 1 of the study, which is being conducted at leading pediatric cancer centers across the United States, including Lurie Children’s Hospital in Chicago, Dana-Farber Cancer Institute in Boston and University of California in San Francisco.

Fighting breast cancer with nanotech, immunotherapy

On September 14, 2020 A team of scientists led by aresearcher at the Case Western Reserve University School of Medicine reported that it is making strides to fight deadly metastatic breast cancer by combining nanotechnology with immunotherapy (Press release, Case Western Reserve University, SEP 14, 2020, View Source [SID1234565160]).

Efstathios "Stathis" Karathanasis, an associate professor of biomedical engineering, is directing the novel technique—sending nanoparticles into the body to wake up "cold" tumors so they can be located and neutralized by immune cells. The team also includes researchers from Cleveland Clinic and Duke University.

Nanotechnology manipulates matter at the nanoscale—microscopically at dimensions measured by nanometers or one-billionth of a meter—to create structures, devices and systems for medical and other uses.

Immunotherapy uses drugs to help a patient’s immune system fight cancer, as opposed to chemotherapy, which uses drugs to directly kill cancer cells, according to the National Cancer Institute (NCI).

The NCI recently awarded a five-year, $3 million grant to Karathanasis and his team to continue their research, initially on animal models with an eye toward human trials. Much of the groundwork behind the project is described in a paper published in Cancer Research, the official journal of the American Association for Cancer Research (AACR) (Free AACR Whitepaper).

"We believe our work shows that this combination of nanotechnology with cancer immunotherapy encompasses an inherent promise to treat the most hard-treat metastatic cancers," Karathanasis said. "Our work has been to design a nanoparticle that triggers an activation of antigen-presenting cells in the tumor. Within a few weeks, the patient can have adapted T cells that recognize and fight the cancer."

Metastatic cancer problem
Breast cancer is the second-leading cause of death from cancer in women in the United States (behind skin cancer), killing more than 42,000 a year; metastatic breast cancer will cause the vast majority of those deaths. Also called Stage IV Cancer, it is breast cancer that has spread to another part of the body, most commonly the liver, brain, bones, or lungs.

Metastatic cancer cells are often considered stealth killers, "ticking time bombs that remain dormant until they emerge as incurable tumors," Karathanasis said.

That means one of the most difficult aspects of diagnosing and treating metastatic breast cancer is that the cells often cannot be found until it is too late for successful treatment.

"They are just sitting there, without dividing, or doing it so slowly that they cannot be detected or treated by any current therapy," Karathanasis said.

And immunotherapy, while offering cancer patients new hope as the science continues to develop, is only successful about 20% of the time.

"When immunotherapy works, it’s highly effective by using our most potent weapon, our own immune system. But cancer cells hijack and recruit the local immune cells in tumors making them dysfunctional, unfortunately," Karathanasis said. "If there are no danger signals from the body, the immune system doesn’t know there is an enemy."

Nanotechnology solution
Karathanasis, an engineer by training who began to work on nanotechnology solutions to medical problems about two decades ago, has devised a way to get the tumor to notify the body’s innate immune system—and the other immunotherapeutic interventions—of its presence.

Initially, when a tumor appears in the body, our immune cells should recognize it and send out cells to try to "kill the enemy" and also "memorize" it, so they can come back and kill it again in the case of tumor recurrence, Karathanasis said.

But then, the tumor adapts and essentially goes undercover, repressing any immune cells, so that it cannot be found by the standard surveillance of the immune system.

Karathanasis and his team have engineered a nanoparticle to "trigger the antigen-presenting cells in the tumor to start generating fresh signals," he said.

The research team also includes: William Schieman, the Goodman-Blum Professor in Cancer Research, Case Western Reserve School of Medicine; Li Lily Wang, associate staff, Cleveland Clinic Lerner Research Institute; and Christopher Hoimes (Duke University School of Medicine).

"We are taking a cold tumor and making it ‘hot’ again," Karathanasis said. "We are unlocking the immune system, which has been repressed by the tumor. We regenerate the cycle of immunity."

New study from MD Anderson and BridgeBio’s Navire Pharma shows SHP2 inhibition overcomes multiple therapeutic-resistance mechanisms in lung cancer

On September 14, 2020 New preclinical research from The University of Texas MD Anderson Cancer Center and BridgeBio Pharma, Inc. affiliate Navire Pharma, Inc., reported that finds that the novel SHP2 inhibitor IACS-13909 is able to overcome multiple therapeutic-resistance mechanisms in non-small cell lung cancer (NSCLC), suggesting a possible new approach to treating cancers that have developed resistance to the targeted EGFR inhibitor osimertinib (Press release, MD Anderson, SEP 14, 2020, View Source [SID1234565159]).

The data is published today in Cancer Research, a journal of the American Association for Cancer Research (AACR) (Free AACR Whitepaper). IACS-13909 is a potent and selective allosteric SHP2 (Src homology 2 domain-containing phosphatase) inhibitor developed through collaboration between Navire and MD Anderson’s Therapeutics Discovery division. Based on these data, Navire plans to launch a clinical study of SHP2 inhibitors by the end of 2020 at multiple US sites, including MD Anderson.

IACS-13909 was initially discovered as an SHP2 inhibitor by a team of scientists in MD Anderson’s Institute for Applied Cancer Science (IACS) and Translational Research to Advance Therapeutics and Innovation in Oncology (TRACTION) platforms, both engines within the Therapeutics Discovery division.

"Tyrosine kinase inhibitors, like osimertinib, appear initially effective in suppressing tumor growth, but multiple mechanisms of resistance can develop while a patient is still receiving treatment," said Nancy Kohl, Ph.D., a senior author of the study and member of Navire’s scientific advisory board. "This study shows that IACS-13909’s ability to inhibit a protein downstream of multiple signaling pathways is a promising approach in overcoming these common tumor-resistance mechanisms."

Osimertinib is a targeted EGFR inhibitor used as a front-line option for treating patients with NSCLC harboring specific EGFR mutations. However, NSLCs frequently develop osimertinib resistance over time, either through additional mutations in EGFR that block activity of the drug, or by activating compensatory signaling pathways.

SHP2 is a protein that acts downstream in these pathways, and it is required for full activation of the MAPK signaling pathways, which is known to fuel tumor growth, proliferation and survival.

"Our findings show that IACS-13909 is capable of suppressing tumor cell proliferation in vitro and causing tumor regression in vivo for lung cancers harboring a variety of activated kinases as the oncogenic driver," said lead author Yuting Sun, Ph.D., co-project lead and senior research scientist with TRACTION at MD Anderson. "These data suggest that targeting SHP2 could provide a viable strategy for overcoming osimertinib resistance occurring through a variety of mechanisms."

These results were consistent when IACS-13909 was used as a single agent and in combination with osimertinib in vivo. The combination treatment in vitro led to prolonged, more durable responses in tumors that were sensitive to osimertinib and stimulated tumor regression in osimertinib-resistant models.

"Through our collaboration with the Therapeutics Discovery team at MD Anderson, we continue to uncover SHP2’s critical role in activating multiple different pathways related to cancer’s onset and growth," said Eli Wallace, chief scientific officer of oncology at BridgeBio, Navire’s parent company. "This study further supports the very reason that Navire was founded – to develop novel SHP2 insights into targeted medicines for patients in need. We look forward to advancing our lead SHP2 inhibitor into the clinic later this year."

The ongoing research is supported by Navire through a global licensing and development agreement, and the Therapeutics Discovery division is supported in part by MD Anderson’s Moon Shots Program. MD Anderson has an institutional financial conflict of interest with Navire, and the research is managed according to MD Anderson’s Institutional Conflict of Interest Management and Monitoring Plan.
