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 Immutep Limited (ASX: IMM; NASDAQ: IMMP) ("Immutep" or "the Company"), a biotechnology company developing novel immunotherapy treatments for cancer and autoimmune diseases, advises that its Chief Medical Officer and Chief Scientific Officer, Dr. Frédéric Triebel, reported it will present interim results from the three initial patient cohorts of its ongoing TACTI-mel Phase I clinical trial in a global webcast and Q&A (Press release, Immutep, MAY 17, 2018, View Source [SID1234526798]).

Dr. Triebel will also present a subset of these interim results at the 3rd Annual Advances in Immuno-Oncology Congress, on 25 May 2018 in London, UK. The presentation, titled "Two ACTIve Immunotherapies in melanoma (TACTI-mel): results of a phase I trial with metastatic melanoma patients treated with a soluble LAG-3 receptor (LAG-3Ig or eftilagimod alpha) as an antigen presenting (APC) activator combined with pembrolizumab" will be released to the market to coincide with the event and made available on the Company’s website.

Immutep’s current lead product is eftilagimod alpha ("efti" or "IMP321"), a potential first-in-class major histocompatibility complex class II ("MHC II") agonist and antigen presenting cell ("APC") activator. Efti is a soluble LAG-3Ig fusion protein based on the LAG-3 immune control mechanism. This mechanism plays a vital role in the regulation of the T cell immune response. Efti, unlike blocking antibodies, is unique as it uses LAG-3 itself as a tool to activate the immune system via MHC II molecules.

The TACTI-mel Phase I clinical trial is a multi-center, open-label clinical trial evaluating the combination of efti with pembrolizumab (KEYTRUDA) for unresectable or metastatic melanoma. As previously disclosed, interim results from the first three cohorts was expected in H1 2018. The trial remains ongoing, following its expansion by an additional cohort, with results from this additional cohort expected in H2 2018.

About the TACTI-mel clinical trial

The ongoing TACTI-mel (Two ACTive Immunotherapies in melanoma) Phase I clinical trial is a multi-center, open-label, dosing escalating (1, 6 or 30 mg of eftilagimod alpha or "efti") study evaluating the combination of efti with pembrolizumab for 6 months, starting at treatment cycle 5 in unresectable or metastatic melanoma patients that have had either a suboptimal response or had disease progression with pembrolizumab monotherapy (clinicaltrials.gov identifier NCT 02676869). The initial study consists of three cohorts of six patients.

In February 2018, Immutep expanded the TACTI-mel study by an additional cohort of 6 patients at 30 mg of efti in combination with pembrolizumab starting at cycle 1 and with a treatment duration of 12 months. As announced on March 22, 2018, the first patient from this additional cohort has received their first dose.

On May 17, 2018 Provectus and POETIC reported preclinical PV-10 data from pediatric cancer research that will be presented at the 2018 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) ("ASCO") Annual Meeting in Chicago, IL (Press release, Provectus Pharmaceuticals, MAY 17, 2018, View Source [SID1234526789]).

PV-10 induced cell death in pediatric solid tumor cell lines derived from relapsed pediatric neuroblastoma, Ewing sarcoma, rhabdomyosarcoma, and osteosarcoma with a measurable therapeutic window compared to normal cells. Western blot analyses of cells treated with PV-10 indicated induction of apoptosis. Drug combination studies showed synergy with radiation and agents that target mitosis. Xenograft studies showed significant reduction of tumor burden in PV-10-treated mice compared to control animals, with a corresponding increase in overall survival.

Provectus Biopharmaceuticals, Inc. (OTCQB: PVCT, www.provectusbio.com) ("Provectus" or the "Company") is a clinical-stage biotechnology company developing PV-10 as the first small molecule oncolytic immunotherapy for adult and pediatric solid tumor cancers. The Pediatric Oncology Experimental Therapeutics Investigators’ Consortium ("POETIC") is a group of North American academic medical centers developing new pediatric cancer therapies.

Findings will be highlighted in a poster presentation on Saturday, June 2 from 8:00 to 11:30 a.m. CDT in Hall A as part of the Pediatric Solid Tumors topic during the Pediatric Oncology session. The POETIC poster title is "In vitro and xenograft anti-tumor activity, target modulation and drug synergy studies of PV-10 against refractory pediatric solid tumors," the poster board number is 230, and the abstract number is 10557.

This preclinical pediatric cancer research was led by Aru Narendran, MD, PhD and researchers at the POETIC Laboratory for Pre-Clinical and Drug Discovery Studies at the University of Calgary (Canada), together with Tanya Trippett, MD, Director of POETIC and researchers at Memorial Sloan Kettering Cancer Center.
