Cancer Targeted Technology Files Investigational New Drug Application for CTT1403, a Novel Radiotherapeutic Drug for Prostate Cancer

On November 6, 2018 Cancer Targeted Technology (CTT), a privately-held Seattle-based biotechnology company, reported that it filed an Investigational New Drug Application (IND) with the FDA to move forward a radiotherapeutic drug, CTT1403, into human clinical trials for prostate cancer (Press release, Cancer Targeted Technology, NOV 6, 2018, View Source [SID1234530938]). CTT1403 is a peptidomimetic drug that targets Prostate Specific Membrane Antigen (PSMA). PSMA is over-expressed on prostate cancer and this expression increases as the cancer metastasizes and becomes hormone-resistant. Unlike other drugs, CTT’s molecules bind irreversibly to PSMA. This distinctive mode of binding enhances uptake and results in rapid and extensive internalization of these drugs by tumor cells, leading to increased uptake within the tumor. CTT1403 is labeled with the radionuclide 177-Lutetium and, unlike other PSMA-targeted drugs in clinical development, contains a unique albumin binding component. The albumin binding moiety on CTT1403 acts to increase the circulation of the drug in the body and further substantially increases the dose of drug that accumulates at the tumor sites. Once targeted to the tumor, the radionuclide on CTT1403 leads to tumor cell destruction. CTT1403 has shown excellent safety results to date in animal studies and CTT1403 treatment results in prolonged survival of animals with prostate cancer tumors

"We are very excited with the potential for CTT1403 to make a difference in men with advanced stage prostate cancer. This is a highly innovative molecule that combines excellent PSMA-targeting characteristics, already proven effective in prostate cancer, with the ability to enhance circulation time allowing for greater anti-tumor effects," stated Dr. Beatrice Langton-Webster, CTT’s CEO and Principal Investigator for the clinical program. The unique chemical structure for CTT1403 was designed by Dr. Cliff Berkman, Professor of Chemistry at Washington State University (WSU) and consultant to CTT as its Chief Scientific Officer. The work to discover and progress CTT1403 through preclinical development to IND was funded by a $2.3M Small Business Innovation Research contract from the NIH.

CTT recently completed clinical trials of CTT1057, the companion PET diagnostic to CTT1403, with excellent safety and imaging results. CTT1057 is undergoing further development and commercialization by CTT’s licensing partner AAA/Novartis. CTT1057 and CTT1403 can act as a theranostic pair to both diagnose and treat prostate cancer. Phase I clinical trials for CTT1403 are expected to start January, 2019.

Yuhan signs $1.25 billion licensing deal with Janssen

On November 6, 2018 South Korean pharma company Yuhan Corp (KS: 000100) reported it has licensed out its new clinical-stage lung cancer drug to Janssen Biotech, a unit of US healthcare giant Johnson & Johnson (NYSE: JNJ), in a deal potentially valued at up to $1.25 billion, according to the Korea Herald and other local media (Press release, Genosco, NOV 6, 2018, View Source [SID1234531533]).

11/16/2018 Yuhan signs $1.25 billion licensing deal with Janssen View Source 2/3 Yuhan said it had entered a licensing and cooperation agreement with Janssen to develop lazertinib, a novel clinical-stage therapeutic candidate for the treatment of patients with non-small cell lung cancer (NSCLC).

Following news of the agreement, shares of Yuhan spiked 29.78% to close at 231,000 won on Monday.
Deal includes $50 million upfront payment
Under the terms of the agreement, Yuhan will receive an upfront payment of $50 million and is eligible to receive up to $1.205 billion in potential
development and commercial milestone payments, along with tiered double-digit royalties on future net sales.
"Yuhan is committed to developing lazertinib as an effective treatment option for patients suffering from NSCLC. And Janssen, with strong
scientific expertise in lung cancer and oncology, is the best strategic partner to achieve this mission," said Lee Jung-hee, president and chief
executive of Yuhan, adding: "We are excited to start this collaboration and dive into advancing this treatment regimen with a focus on improving
the lives of people who suffer from lung cancer."
The compound is currently in an ongoing Phase I/II clinical trials in Korea. Interim results showed that lazertinib exhibited robust disease activity
in patients with NSCLC with acquired resistance to EGFR-TKIs, with or without brain metastasis and was well tolerated with low rates of Grade 3
or higher adverse events.
In 2015, US firm Genosco partnered globally with Yuhan for development and commercialization of lazertinib, on which data from a Phase I/II
study in NSCLC were presented at the annual American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) meeting in June this year.
Results from the open-label, multi-center dose-escalation, Phase I/II study of lazertinib (YH25448, GNS-1480) for patients with advanced EGFRTKI-resistant
NSCLC with or without CNS metastasis concluded that lazertinib was well-tolerated with low rates of Grade 3 or higher adverse
events (AE) and exhibited robust activity in patients with NSCLC with acquired resistance to EGFR-TKIs, with or without brain metastasis.

"The expanded agreement we have signed with Roche, covering up to three new targets, speaks to the compelling and ongoing value proposition of our ENHANZE technology," said Dr. Helen Torley, president and chief executive officer. "The overall progress we made recently with the initiation of two Phase 1 trials combining ENHANZE with Alexion’s ALXN1210 and Bristol-Myers Squibb’s BMS-986179, an investigational anti-CD-73 antibody, reinforces our confidence in the potential for $1 billion in royalty revenue in 2027 and for up to $1 billion in cumulative lifetime milestone payments associated with our partners’ programs."

"Turning to our second potential growth engine, PEGPH20, we continue to make good progress with our pivotal HALO-301 pancreas cancer study and in our exploration of the pan tumor potential of PEGPH20. We are pleased to have moved into the randomization phase of our study in patients with cholangiocarcinoma and gall bladder cancer in August. Interest is high, with enrollment progressing very well in the randomization phase to date."

Third Quarter 2018 and Recent Highlights Include:

Halozyme licensed its ENHANZE drug-delivery technology to Roche for exclusive development of a new undisclosed clinical stage therapeutic target, with an option for Roche to select two additional targets within four years. Halozyme will receive an initial payment of $25 million, which will be recognized as revenue in the fourth quarter, with the potential to earn additional payments of up to $160 million to $165 million per target, subject to the achievement of specified development, regulatory and sales-based milestones. Halozyme will also receive mid-single digit royalties on sales of commercialized products.
Bristol-Myers Squibb has dosed the first subject in a Phase 1 clinical trial evaluating the safety, pharmacokinetics and pharmacodynamics of BMS-986179. This investigational anti-CD-73 antibody is being tested in combination with Halozyme’s proprietary ENHANZE drug delivery technology.
Alexion continuing to progress ALXN1210 with ENHANZE, which advanced into Phase 1 clinical testing in the third quarter of 2018.
Health Canada approves a subcutaneous (SC) formulation of trastuzumab (Herceptin SC) for the treatment of patients with HER2-positive breast cancer. Additionally, the U.S. Food and Drug Administration accepted a Biologics License Application from Genentech for a subcutaneous (SC) formulation of trastuzumab (Herceptin SC) in July 2018.
Data presentations from two clinical trials for PEGPH20 (pegvorhyaluronidase alfa) in patients with advanced pancreas and metastatic breast cancer at ESMO (Free ESMO Whitepaper) 2018. These data reinforce the potential for PEGPH20 in combination with chemotherapy and its ability to degrade tumor hyaluronan, which could allow for greater penetration of chemotherapy and improved access of the immune system to the tumor.
Janssen continuing in multiple ongoing trials of a subcutaneous formulation of DARZALEX (daratumumab) in support of plans for commercialization. Halozyme’s ENHANZE technology has the potential to enable a 15-ml injection to be delivered in five minutes or less. Ongoing trials in patients with multiple myeloma, amyloidosis and smoldering myeloma include four Phase 3 studies. Two additional Phase 3 trials, which are listed on clinicaltrials.gov, are planned and expected to begin shortly.
Progress continues in the HALO-301 trial in screening and enrolling patients. The company projects that an interim analysis of the first primary endpoint of progression free survival will be conducted upon achievement of the target number of events in the December 2018 to February 2019 time frame. The trial is investigating PEGPH20 in combination with ABRAXANE (nab-paclitaxel) and gemcitabine in first-line metastatic pancreas cancer patients with high levels of tumor hyaluronan (HA-High).
Strengthened management team and board of directors, with the appointment of Benjamin Hickey as Chief Commercial Officer and Bernadette Connaughton to the board of directors.
Third Quarter 2018 Financial Highlights

Revenue for the third quarter was $25.6 million compared to $63.7 million for the third quarter of 2017. The year-over-year decrease was driven by a one-time $30 million upfront license fee from Roche received in the prior year and an expected decrease in bulk rHuPH20 sales to partners and research and development reimbursements. The decrease was offset by a 9 percent growth in royalties on a reported basis from partner sales. Revenue for the third quarter included $18.7 million in royalties and $3.7 million in HYLENEX recombinant (hyaluronidase human injection) product sales.
Research and development expenses for the third quarter were $35.5 million, compared to $34 million for the third quarter of 2017.
Selling, general and administrative expenses for the third quarter were $14.9 million, compared to $13.3 million for the third quarter of 2017.
Net loss for the third quarter was $27.9 million, or $0.19 per share, compared to net income in the third quarter of 2017 of $2.7 million, or $0.02 per share.
Cash, cash equivalents and marketable securities were $364.4 million at September 30, 2018, compared to $469.2 million at December 31, 2017.
Financial Outlook for 2018

For the full year 2018, the company is updating its prior guidance ranges for net revenue, operating expenses, operating cash burn and year-end cash, and is now expecting:

Net revenue of $150 million to $160 million, an increase from the prior range of $125 million to $135 million, driven by the $25 million upfront payment from the recent Roche ENHANZE license agreement expected in the fourth quarter;
Operating expenses to $220 million to $230 million, a reduction from the prior range of $230 million to $240 million;
Operating cash burn of $50 million to $60 million compared to the prior range of $75 million to $85 million; and
Year-end cash balance of $340 million to $350 million, an increase from the prior range of $310 million to $320 million, driven by the $25 million upfront payment from the recent Roche ENHANZE agreement, and the reduction in operating expenses, partially offset by changes in our working capital.

OncoSec Reports Preliminary Data from
KEYNOTE-695 Phase 2b RegistrationDirected Clinical Trial of TAVO™ in Combination with KEYTRUDA® for
Metastatic Melanoma at Society for
Immunotherapy of Cancer’s 33rd Annual
Meeting

On November 6, 2018 OncoSec Medical Incorporated (OncoSec) (NASDAQ: ONCS), a company developing novel cancer immunotherapies based on its proprietary technology generating sustained intratumoral IL-12 levels, today reported preliminary data from KEYNOTE-695, a global, multicenter Phase 2b, open-label trial of intratumoral delivery of TAVO (tavokinogene telseplasmid / IL-12) with intravenous KEYTRUDA (pembrolizumab) in patients with unresectable, advanced melanoma (Press release, OncoSec Medical, NOV 6, 2018, View Source [SID1234530797]). Eligible patients had refractory, locally advanced or metastatic disease defined as unresectable Stage III/IV metastatic melanoma that had definitively progressed on a full-course of anti-PD-1 treatment with KEYTRUDA (pembrolizumab) or OPDIVO (nivolumab).

As of September 1, 2018, 21 patients had been enrolled in the study. Out of the 21 patients, nine patients had completed 12 weeks of treatment and reached the first tumor evaluation point at approximately 12 weeks, while the remaining 12 patients had not yet reached the first tumor evaluation. All nine patients were previously treated and definitively progressed on anti-PD-1 therapies with 56% (5/9) having had more than one prior line of therapy. All enrolled patients had exceedingly low frequencies of intratumoral CD8+ peCTL (PD-1+/CTLA-4+) at screening with a notable increase in TIL density following treatment.

Two of the nine patients experienced a partial response and one patient had stable disease (22% BORR and 33% DCR) by RECIST v1.1. Tumor responses were noted in both treated and untreated lesions. Of the two responding patients, both had multiple prior rounds of anti-PD-1 therapy, with no response, and one had also progressed after 4
cycles of OPDIVO and YERVOY (ipilimumab), an FDA-approved anti-CTLA4 / anti-PD1 antibody combination. Tumor responses were associated with treatment-related upregulation of immune-based transcripts in the tumor microenvironment, as well as increased frequencies of intratumoral T cells within three weeks of therapy.

"There is currently no approved therapy for the KEYNOTE-695 patient population. A 10% response rate is considered meaningful in this cohort, since this is about what we expect with additional chemotherapy, however, such responses lack durability. The preliminary tumor responses (22% BORR and 33% DCR) and supporting immune data observed here for the first time are important," said Adil Daud, MD, HS Clinical Professor, Department of
Medicine (Hematology/Oncology), UCSF; Director, Melanoma Clinical Research, UCSF Helen Diller Family Comprehensive Cancer Center.

KEYNOTE-695 enrollment criteria with respect to anti-PD-1 checkpoint failure is highly restrictive. In order to be considered an anti-PD-1 checkpoint failure, all patients must have Stage III/IV metastatic melanoma progressive disease after at least four prior cycles of either KEYTRUDA or OPDIVO. Disease progression is determined according to RECIST v1.1, measured by radiologic assessment, with confirmation of progression by second assessment. All patients must receive their first TAVO / KEYTRUDA combination treatment within 24 weeks of the last dose of an FDA approved anti-PD-1 therapy, with no intervening therapies between such failure and KEYNOTE695 enrollment. Patients that were BRAF eligible must have received and progressed
following BRAF treatment.

"Although several clinical studies have reported late-stage melanoma data in anti-PD-1 failures, such failures are inconsistently defined. This is a critical point," continued Dr. Daud. "Since patients in KEYNOTE-695 have unequivocally failed approved anti-PD-1 therapies, these preliminary data, viewed in this context, carry weight."
TAVO was well-tolerated, with Grade 1 adverse advents associated with injection site or procedural pain. One TAVO related Grade 3 SAE of cellulitis was reported and resolved.

KEYNOTE-695 is a registration-enabled clinical trial. In order to be eligible for accelerated approval, a product candidate must treat a serious condition and provide a meaningful advantage over available therapies. In early 2017 and prior to the commencement of the study, the Company reviewed the patient inclusion criteria with FDA so that KEYNOTE695 could be submitted to FDA for accelerated approval. KEYNOTE-695 is expected to
be completed in 2019. Based on the outcome of the study and feedback from FDA, the Company plans to file for accelerated approval by end of 2019 or early 2020.

TAVO has received both Orphan Drug and Fast-Track Designation by the U.S. Food & Drug Administration.
