Kite adds to T-cell receptor platform with HiFiBiO deal


Gilead’s Kite is paying $10 million upfront to tap into a neoantigen screening platform developed by Hong Kong biotech HiFiBiO Therapeutics to discover T-cell receptors (TCRs) for cancer.
The two companies say they will adapt the platform to scale up and accelerate the screening process so that it can be applied to cells taken from patient samples—potentially allowing the development of targeted, personalized cellular immunotherapies.
Neoantigen are driving a new form of personalized immunotherapy in which antigens that are found in diseased tissues but not normally in healthy patients are used to develop targeted therapies. That ties in neatly with Kite’s TCR platform, which involves identifying receptors that bind to tumor antigens, modifying autologous peripheral blood T cells to express them and then administering them to patients.

The biotech has been working in the neoantigen/TCR space for some time through a collaboration with the National Institutes of Health (NIH) to discover mutations in oncogenes such as KRAS that can be targeted with T-cell therapies. Two years ago, the partners published a case study of a patient with metastatic colorectal cancer who was successfully treated with T cells that targeting the KRAS G12D mutation.
Since then, Kite has advanced its lead TCR candidates into clinical trials, including KITE-439 for HPV-associated solid tumors—which has initial phase 1 results and also grew out of the NIH collaboration—and MAGE A3/A6-targeted KITE-718.
“Neoantigen-based cell therapy is a very exciting, yet complex, area of research that has the potential to transform the way we treat many solid tumors,” said Alessandro Riva, M.D., who heads up Gilead’s oncology therapeutics and cell therapy programs.
“We are excited about this collaboration with HiFiBiO, which will build upon our existing capabilities focused on discovering cell therapies which target patient-specific tumor neoantigens.”
In return for its $10 million, Kite is taking an exclusive option to license HiFiBiO’s platform to screen T cells for receptors that can be used in engineered T-cell therapies, while the Hong Kong company is also in line for undisclosed milestone payments.
This is the second platform strengthening deal for Kite’s TCR program in the last few months, coming after it took an option to buy Dutch biotech Gadeta and its gamma delta TCR technology.

Tilray Proposes Private Placement of $400 Million of Convertible Senior Notes


Tilray Inc. (NASDAQ:TLRY), a global leader in cannabis research, cultivation, production and distribution, today announced that it intends to offer, subject to market conditions and other factors, $400 million aggregate principal amount of Convertible Senior Notes due 2023 (the “notes”) in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The notes will be sold to accredited investors in Canada pursuant to an exemption from the prospectus requirements of Canadian securities laws. Tilray also intends to grant the initial purchasers of the notes an option to purchase up to an additional $60 million aggregate principal amount of notes.
Tilray intends to use the net proceeds from this offering for working capital, future acquisitions and general corporate purposes, and to repay the approximately $9.1 million existing mortgage related to its facility in Nanaimo, British Columbia.
The notes will be senior unsecured obligations of Tilray and will accrue interest payable semiannually in arrears.

The interest rate, initial conversion rate, repurchase or redemption rights and other terms of the notes will be determined at the time of pricing of the offering.
Neither the notes, nor any shares of Tilray’s Class 2 common stock issuable upon conversion of the notes, have been registered under the Securities Act or any state securities laws, or qualified for distribution by prospectus in Canada, and unless so registered, may not be offered or sold in the United States absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and other applicable securities laws, or sold in Canada absent an exemption from the prospectus requirements of Canadian securities laws.

Bionomics Announces that BNC210 Doesn’t Treat PTSD Symptoms


Yesterday, top-line data from Bionomics Limited (ASX:BNO, OTCQX:BNOEF) revealed details of the biopharmaceutical company’s Phase II clinical trial of BNC210 in regards to patients with post-traumatic stress disorder (PTSD).  BNC210 is an innovative negative allosteric modulator of the alpha7 nicotinic acetylcholine receptor.
“This trial comprehensively assessed symptoms in 193 patients with PTSD across 25 sites in the US and Australia,”  explained Professor Paul Rolan, Bionomics’ consultant Chief Medical Officer. “We found that BNC210 showed excellent tolerability and safety. This adds to the safety picture for BNC210, administered for the first time over a prolonged 3-month treatment period. Although there was no overall treatment effect assessed by CAPS-5, we saw improvements on select components of the scale that are attributable to the mood and anxiety symptoms of the condition.”
Bionomics (ASX: BNO) is a worldwide clinical stage biopharmaceutical company working to create original drug candidates for cancer and central nervous system (CNS) disorders such as Alzheimer’s disease, anxiety, and depression. “Bionomics has a portfolio of well differentiated drug candidates.  Each target the treatment of serious conditions with significant unmet clinical need, and for which large market opportunities exist. We are able to not only sustain but accelerate our pipeline development by virtue of two distinguishing attributes:  1) high quality drug candidates and 2) our strategic partnering strategy which allows multiple and diverse programs to be optimally developed,” quotes their website. At the BioPharma Asia Industry Awards during the BioPharma Asia Convention in 2014, Bionomics was named as the Innovative Asian Biotech of the Year.
Bionomics consultant Dr. Murray Stein, Distinguished Professor of Psychiatry, Family Medicine and Public Health at the University of California San Diego offered that “there is great unmet medical need for safe and effective treatments for the large population of patients suffering with PTSD worldwide. While challenging to find which symptoms may respond to the novel pharmacological properties of BNC210, there was great anticipation that it would show clear beneficial effects on improving PTSD symptoms, supporting further development of the drug as a novel treatment for this condition. Results of this trial do not demonstrate those broad benefits, underscoring the complexity of PTSD and the heterogeneity of PTSD symptoms across patients. Future work with BNC210 – and other novel compounds – may be best focused on a subset of symptoms, or a subset of patients, considered most likely to benefit.”
Their pipeline divides into the aforementioned two areas of specialty, CNS and oncology. BNC210 is the company’s lead drug candidate, with primary indications in PTSD, agitation, GAD, and panic. Results divulging that the drug has been ineffective may prove to be detrimental to the company’s efforts. Since the announcement yesterday morning, the Bionomics share price has dropped 69%, a 52-week low.
“We are extremely disappointed that the primary endpoint in this trial was not met. As we move forward we will focus on the completion of the ongoing Phase 2 trial of BNC210 in hospitalised, elderly patients suffering from agitation which is anticipated to readout in Q1, 2019. We plan to stop all other work on BNC210 until that time,” disclosed Dr. Deborah Rathjen, CEO & Managing Director of Bionomics. “In FY18 Bionomics reduced costs by closing the US operations and reducing overall headcount. In order to maintain and enhance shareholder value, we are continuing to assess our strategic options for partnering and portfolio prioritisation whilst conserving cash. We will provide an update on our strategic direction at the Annual General Meeting to be held on 14 November.”
“Bionomics has ongoing drug discovery programs which are anticipated to deliver up to two new therapeutic candidates this financial year. We also have a strategic partnership with Merck & Co., (known as MSD outside the United States and Canada), assessing a cognition therapy candidate in an ongoing Phase 1 program, which entered clinical development and triggered a US$10 million milestone payment last year,” added Dr. Rathjen. “This deal has a potential value of up to US$506 million in terms of the upfront payments, R&D payments and milestone payments, plus additional annual royalties on net sales of licensed drugs. Both the MSD partnership and our drug discovery programs reflect the robustness of Bionomics’ pipeline.”

Allogene Therapeutics Eyes IPO of up to $288 Million


Six months after officially launching and one month after securing $120 million in private financing, Allogene Therapeutics is looking to score between $272 and $288 million from an initial public offering.
On Tuesday, Renaissance Capital reported the company founded by former Kite Pharmaexecutives Arie Belldegrun, and David Chang, will offer 16 million shares at a price range of $16 to $18 per share. If the high-end pricing is hit, that would secure $288 million for the company and would, according to Renaissance Capital, give Allogene a “fully diluted market value of $2.1 billion and an enterprise value of $1.4 billion.”
South San Francisco-based Allogene announced its intentions to file for an IPO last month. The company intends to list itself on the Nasdaq Stock Exchange under the ticker symbol “ALLO.” Goldman Sachs & Co. LLC, J.P. Morgan Securities LLC, Cowen and Company, LLC and Jefferies LLC are acting as the joint book-running managers for the proposed offering.
Founded in 2017 and coming out of stealth mode in April, Allogene hit the ground running with $300 million in a Series A financing to develop off-the-shelf CAR-T therapy products. The company’s engineered T-cells are allogeneic, which means they are taken from healthy donors for intended use in any patient. Current approved CAR-T therapies, including Yescarta, which Belldegrun and Chang were instrumental in developing when they were at Kite, are autologous, meaning they are extracted from an individual patient for that patient’s use.
Following Allogene’s launch in April, the company completed an agreement for Pfizer’sallogenic CAR-T portfolio. As part of that deal, Allogene secured the rights to 16 preclinical CAR T assets licensed from Cellectis and Servier and one clinical asset licensed from Servier, UCART19, an allogeneic CAR-T therapy that is being developed for treatment of CD19-expressing hematological malignancies.
In its S-1 filing with the U.S. Securities and Exchange Commission, Allogene said UCART19 is being studied in clinical trials in patients with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL). The company said it anticipates UCART19 will be advanced to registrational trials in the second half of 2019. Additionally, Allogene said the company plans to file an Investigational New Drug Application with the U.S. Food and Drug Administration in the first half of next year for the company’s second allogeneic anti-CD19 CAR T cell product candidate, ALLO-501. That therapy will be for the treatment of relapsed or refractory non-Hodgkin lymphoma.
Allogene also noted in its filing that it has a “deep pipeline” of allogeneic CAR T cell product candidates targeting multiple promising antigens in a host of hematological malignancies and solid tumors.
When Allogene’s stock goes public, Belldegrun and Chang will have about 10 percent and 4 percent of the company’s shares, respectively. Those shares will be worth millions, but it’s a position the two men are well acquainted with. When Gilead Sciences acquired Kite Pharmaceuticals, Belldegrun snagged a nice payday of $694 million. Chang walked away with about $98 million.
Allogene is the latest in a series of biotechs going public. Earlier this week Israel-based Gamida Cell Ltd. filed for a $69 million initial public offering.

Neon Therapeutics to present data from NT-001 at ESMO


Neon Therapeutics announced that updated data from NT-001, its ongoing Phase 1b clinical trial evaluating NEO-PV-01 in the metastatic setting, will be presented in an upcoming oral presentation at the European Society for Medical Oncology, or ESMO.

Oasmia reports Phase 2 dog study meets primary endpoint


Oasmia reported its analysis of the data from the Phase II study and it’s the follow-up has been finalized and summarized in a report. Overall, 17 dogs participated and were treated with Doxophos Vet in the main study and eight of these continuing during the follow-up part. The objective was obtained, as 75% of the dogs with B-cell lymphoma showed a response after at least two treatment cycles. Progression free survival was defined as the time from screening to progression, or death of any cause. The study results confirmed that the dose of Doxophos Vet defined in a prior dose-finding study is appropriate with regards to both efficacy and safety in dogs with lymphoma. The pharmacokinetic profile analyzed shows there is a rapid distribution of doxorubicin into the tissues, and that the Doxophos Vet formulation does not alter the release properties of doxorubicin when infused into the blood. The most frequently reported adverse reaction after Doxophos Vet treatment was myelosuppression. This is the most expected adverse reaction with chemotherapy. Of the majority of the adverse events, 88% in the main study and 69% in the follow-up were mild to moderate.

PTC Therapeutics reports results of risdiplam in spinal muscular atrophy


PTC Therapeutics announced interim clinical data from the Part 1, open-label studies of FIREFISH and SUNFISH demonstrating the ‘benefit’ of risdiplam for the treatment of Type 1, 2 and 3 spinal muscular atrophy. The results showed that patients across all SMA types benefited from an oral systemic therapy indicated by increases in developmental motor milestones. Risdiplam was well tolerated at all doses across studies to date. The SMA program is a collaboration between PTC, the SMA Foundation, and Roche. In Part 1 of the FIREFISH study, at Day 245 of treatment, 43% or 6/14, of infants were able to sit with or without support, including three who achieved unassisted sitting. Natural history indicates that Type 1 SMA babies never achieve this milestone. In Part 1 of the SUNFISH study in Type 2 and 3 SMA patients, 63% or 19/30, of patients treated with risdiplam for at least one year achieved a median increase in motor function of 3.13 points versus baseline. Typically patients with Type 2 or 3 SMA decline by 0.85 to 0.67 point per year. The pivotal portion of the SUNFISH clinical study has completed enrollment. Patients enrolled in the SUNFISH trial have a broad age range (2-24 years; median age 8 years) and with broad functional characteristics.
