Abstract Title: COTI-2, a potent orally available small molecule targeting mutant p53, with promising efficacy as monotherapy and combination treatment in preclinical tumor models
Session Date and Time: Saturday, June 2nd, 2018 1:15 PM – 4:45 PM Central Time
Session Location: McCormick Place South, Hall A, Poster Board 28

Phase 1b/2a Trial of COTI-2
The ongoing Phase 1 trial of COTI-2 is currently evaluating COTI-2 as a monotherapy for the potential treatment of gynecological malignancies and head and neck squamous cell carcinoma ("HNSCC"). In 2017, the Company announced top-line data from the gynecological malignancies arm of the trial demonstrating COTI-2 was generally safe and well-tolerated. COTI-2 also exhibited an encouraging pharmacokinetic/pharmacodynamic profile and signals of efficacy. In March 2018, the Company submitted a protocol amendment to the FDA for to expand the trial to evaluate COTI-2 in combination with various standard of care chemotherapy regimens in a wide spectrum of cancers. Primary outcome measures will evaluate safety and tolerability and determine the maximum tolerated dose and recommended Phase 2 dose for COTI-2 as a combination therapy. Secondary and exploratory outcome measures will evaluate pharmacodynamics and various signals of efficacy. Pending regulatory approval, the Company expects to implement the protocol amendment mid-calendar 2018.

On May 17, 2018 Veru Inc. (NASDAQ: VERU), a urology and oncology biopharmaceutical company, reported the publication of data from preclinical studies of VERU-111, a novel oral alpha and beta tubulin inhibitor, showing potent activity in a highly resistant model of human prostate cancer (Press release, Veru, MAY 17, 2018, View Source [SID1234529113]). An abstract of the data was published as part of the upcoming 2018 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in Chicago.

Oral VERU-111 was evaluated in the 22Rv1 prostate cancer model, which represents a highly resistant and aggressive form of the disease possessing androgen receptor splice variants that are commonly found in prostate cancer resistant to hormonal approaches like abiraterone and enzalutamide. In the same model, docetaxel administered by injection did not have significant effect on tumor growth. Animals receiving docetaxel lost weight on the study, a surrogate for toxicity, whereas those on VERU-111 either maintained or gained weight while receiving the drug.

"The findings in this clinically relevant model of prostate cancer provide us with additional support and enthusiasm for evaluating VERU-111 in a Phase 1/2 clinical trial, which is scheduled to commence later this year. This is an animal model in which few drugs have been shown to be active. In addition, VERU 111 may be effective against other tumor types known to be sensitive to taxanes that are already FDA approved," said Mario Eisenberger, MD, the Dale Hughes Professor of Oncology at The Johns Hopkins University.

"Oral VERU-111 has shown positive and encouraging signs to become an important therapeutic option for a particularly challenging form of prostate cancer. We are studying VERU-111 in multiple other cancers, the data of which is also being published at ASCO (Free ASCO Whitepaper) this year. We have begun performing the required toxicity studies and our IND submission and first clinical studies are planned for later this year," said Mitchell Steiner, M.D., Chairman, President and Chief Executive Officer of Veru.

About VERU-111
VERU-111 is a novel oral therapy targeting alpha and beta tubulin for the treatment of metastatic prostate, breast, endometrial, ovarian, and other cancers. In 2017, there were approximately 161,000 new cases of prostate cancer in the U.S. and about 25% of these men will die from the disease. In the U.S., 5% of men with prostate cancer will have metastatic cancer and up to 30% of men with high-risk, localized prostate cancer will develop metastatic cancer following initial therapy. The median survival of patients with metastatic prostate cancer ranges from 3.2 to 4.5 years. For these men, the 1st line therapy is androgen deprivation therapy, or medical castration. Although most will initially respond, nearly all these patients will progress to metastatic castration resistant prostate and have a poor prognosis with an average survival of 1.5 years. New 2nd line hormonal agents, like XTANDI (enzalutamide) and ZYTIGA (abiraterone/prednisone) have resulted in an additional four to five months of average survival, but nearly all men on these agents will develop progressive metastatic prostate cancer.

Drugs like VERU-111 that target tubulin, the subunits of microtubules, have been shown to be the most effective targeted cytotoxic chemotherapy for the treatment of metastatic prostate cancer. Microtubules are critical for cancer cell replication to stimulate genes for cancer cell proliferation. Docetaxel and cabazitaxel are examples of FDA-approved chemotherapy drugs that are given intravenously (IV) that target tubulin to treat metastatic prostate cancer. Although effective, the challenges for this class of chemotherapy drugs, also known as taxanes, include that they must be given intravenously (IV) and that the cancer cells develop resistance to taxanes. There are also serious safety concerns with IV taxanes which include serious hypersensitivity reactions, myelosuppression and neurotoxicity such as peripheral neuropathy and muscle weakness.

Unlike taxanes which bind to just the beta subunit of tubulin, VERU-111 binds strongly to both the alpha and beta subunits of tubulin. VERU-111 has: high oral bioavailability; less resistance as it does not interact with multiple drug resistance proteins so it cannot be pumped out of the cancer cell; minimal drug to drug interactions and high activity against many tumor types including: prostate cancer resistant to drugs like enzalutamide, AR-V7 positive and taxanes, as well as triple negative breast cancer, ovarian cancer, pancreatic cancer, lung cancer, and melanoma. In preclinical studies, VERU-111 appears to have less toxicity and less suppression of white blood cells compared to taxanes and other chemotherapy agents.

Production of the VERU-111 active pharmaceutical ingredient and preclinical safety toxicology studies required for an IND are expected to be completed in 2018. We anticipate filing an IND in 2018 and Phase 1/2 studies are planned for late 2018. Phase 1 studies of VERU-111 are planned in men who have metastatic prostate cancer that has progressed while taking androgen deprivation therapy and abiraterone or enzalutamide as well as in patients with metastatic breast, endometrial, and ovarian cancers. In the U.S., there is a $5 billion annual market for 2nd line hormone therapies for prostate cancer and a $4.8 billion annual market for IV-given taxanes and vinca alkaloids chemotherapies (docetaxel $1 billion and cabazitaxel $500 million in prostate cancer) per Decision Resources Group and Allied Market Research. Second line hormonal therapies like enzalutamide and abiraterone/prednisone have almost complete cross-resistance and should not be used in sequence for the treatment of metastatic prostate cancer. VERU-111 could be substituted for IV given docetaxel and cabazitaxel antitubulin chemotherapies. VERU-111 could also be developed as an oral dosing alternative to chemotherapies for the treatment of metastatic breast, endometrial and ovarian cancers as these tumors that responded to IV taxane chemotherapies.

On May 17, 2018 Inovio Pharmaceuticals, Inc. (NASDAQ:INO) reported a poster presentation of additional prostate cancer data (Abstract #229675) at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) annual meeting to be held in Chicago, June 1-5, 2018 (Press release, Inovio, MAY 17, 2018, View Source [SID1234526752]). Previously reported data from a Phase 1b clinical trial demonstrated that Inovio’s cancer immunotherapy (INO-5150) slowed PSA rise in patients with biochemically recurrent prostate cancer. Additional analyses show clinically meaningful PSA stabilization post-administration of Inovio’s immunotherapy in patients with no documented disease progression during the study. Of note, this effect was also observed in the patients with the fastest PSA doubling at the time of study entry.

The multi-center Phase 1b study enrolled 62 patients with biochemically relapsed prostate cancer following definitive local therapy. Under the trial design, eligible patients received INO-5150 (DNA plasmids encoding prostate specific antigen (PSA) and prostate specific membrane antigen (PSMA)) alone or co-administered with INO-9012 (IL-12 plasmid) delivered intramuscularly followed by EP using the CELLECTRA-5P device. Of the 61 evaluable patients, 77% (47/61) demonstrated T cell immunogenicity, and 38% (19/50) exhibited CD38+, Perforin+CD8+ T cell responses. Additional analyses are underway to elucidate the correlation between immunologic efficacy and clinical benefit. For more information, please visit ClinicalTrials.gov (Identifier: NCT02514213).

Dr. J. Joseph Kim, Inovio’s President & CEO, said, "The additional results from our Phase 1b INO-5150 study continue to support our rationale that Inovio’s T cell generating INO-5150 could be an important agent as an immunotherapy as it provides strong and durable immune responses in a particularly difficult-to-treat prostate cancer patient population. We remain diligent on establishing an outside partnership to further advance INO-5150 and I look forward to sharing additional observations from our prostate cancer development program later this year."

INO-5150 was generated using Inovio’s proprietary ASPIRE technology process to enable significant production of engineered PSA and PSMA antigens with genetic sequences differentiated from native human PSA and PSMA sequences. This patented approach is designed to help the body’s immune system overcome its "self-tolerance" to prostate cancer cells and mount a strong targeted CD8+ killer T cell response to eliminate the cancerous cells displaying these antigens. PSMA is also one of 3 antigens comprising INO-5401, which is being tested in two separate Phase 1/2 trials as an immunotherapy to treat glioblastoma and metastatic bladder cancer in combination with Regeneron and Genentech/Roche’s checkpoint inhibitors, respectively.

Independently, as part of the active, ongoing collaboration, two additional posters are being presented at the ASCO (Free ASCO Whitepaper) meeting that provide details on the ongoing trials of AstraZeneca/MedImmune’s MEDI0457 (formerly called INO-3112 which MedImmune in-licensed from Inovio) in abstract #TPS6093 and #5525.

"Following our positive results for selinexor in the STORM study in patients with penta-refractory multiple myeloma, we are pleased to be presenting updated results of selinexor combinations in earlier lines of myeloma treatment," said Sharon Shacham, PhD, MBA, President and Chief Scientific Officer of Karyopharm. "In the previously reported Phase 1b/2 STOMP study results, selinexor has shown robust anti-myeloma activity and a manageable safety profile in patients with relapsed or refractory myeloma after at least one prior therapy. The STOMP results not only provide the underlying clinical rationale for the ongoing pivotal Phase 3 BOSTON study evaluating selinexor in combination with once weekly Velcade, but also provide supportive data for selinexor as a potential new backbone therapy in combination with approved myeloma therapies, often with synergistic activity. We look forward to sharing these updated STOMP results from the Velcade, Pomalyst and Darzalex arms with the medical community at EHA (Free EHA Whitepaper) this year."

About Selinexor

Selinexor (KPT-330) is a first-in-class, oral Selective Inhibitor of Nuclear Export / SINE compound. Selinexor functions by binding with and inhibiting the nuclear export protein XPO1 (also called CRM1), leading to the accumulation of tumor suppressor proteins in the cell nucleus. This reinitiates and amplifies their tumor suppressor function and is believed to lead to the selective induction of apoptosis in cancer cells, while largely sparing normal cells. To date, over 2,400 patients have been treated with selinexor. In April 2018, Karyopharm reported positive top-line data from the Phase 2b STORM study evaluating selinexor in combination with low-dose dexamethasone in patients with penta-refractory multiple myeloma. Selinexor has been granted Orphan Drug Designation in multiple myeloma and Fast Track designation for the patient population evaluated in the STORM study. Karyopharm plans to submit a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) during the second half of 2018, with a request for accelerated approval for oral selinexor as a new treatment for patients with penta-refractory multiple myeloma. The Company also plans to submit a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) in early 2019 with a request for conditional approval. Selinexor is also being evaluated in several other mid- and later-phase clinical trials across multiple cancer indications, including in multiple myeloma in a pivotal, randomized Phase 3 study in combination with Velcade (bortezomib) and low-dose dexamethasone (BOSTON) and as a potential backbone therapy in combination with approved therapies (STOMP), and in diffuse large B-cell lymphoma (SADAL), liposarcoma (SEAL), and an investigator-sponsored study in endometrial cancer (SIENDO), among others. Additional Phase 1, Phase 2 and Phase 3 studies are ongoing or currently planned, including multiple studies in combination with one or more approved therapies in a variety of tumor types to further inform Karyopharm’s clinical development priorities for selinexor. Additional clinical trial information for selinexor is available at www.clinicaltrials.gov.
