Financial Summary

Reported loss of $7.3M (Dec 2017: $6.2M); and
Cash position at 31 December 2018 of $44.4M (June 2018: $51.3M), which excludes the expected $4.0M FY18 R&D tax incentive to be received.
VivaGel

VivaGel BV was licensed to ITF Pharma, Inc., for the US for milestones of up to US$101M in addition to escalating, double-digit royalties;
Starpharma and its partners, Mundipharma and Aspen, undertook extensive preparations for the upcoming launches of VivaGel BV in multiple regions scheduled for the first half of 2019. Extensive marketing activities such as packaging design, sales staff training, promotional material development, and launch meetings occurred in parallel with supply chain activities. Manufactured product has been delivered to Aspen subsequent to half-year end, and manufacturing of product for Europe is well-advanced;
US FDA completed its review of the VivaGel BV NDA and advised it requires confirmatory clinical data prior to approval. In preparation for a meeting with the FDA to discuss the data required, Starpharma has been working closely with expert FDA consultants and is currently awaiting confirmation of the meeting date;
VivaGel condom received final regulatory approval in Japan and Starpharma’s partner, Okamoto, commenced launch activities; and
Positive independent market research was conducted in the US for SPL7013 ophthalmic drops for viral conjunctivitis and a patent was granted for the product.
DEP Drug Delivery

Recruitment activities progressed well for two DEP clinical trials – for DEP docetaxel (phase 2) and DEP cabazitaxel (phase 1 / 2), with new sites opened to support recruitment. Efficacy signals have been observed in a number of patients and both products continue to exhibit a notable lack of bone marrow toxicity and other common side effects including hair-loss, anaphylaxis and oedema;
Final preclinical work for the DEP irinotecan phase 1 / 2 trial was completed, study product was manufactured, and other trial preparations, including CRO/site selection, are well advanced ahead of the planned trial commencement later in FY19;
AstraZeneca’s first patent application on DEP Bcl2/xL inhibitor conjugates was published and included compelling efficacy data on DEP Bcl2/xL inhibitor conjugates, both alone and in combination with market-leading anti-cancer treatments, in various human leukemia models;
DEP irinotecan showed impressive efficacy and safety benefits over standard irinotecan in combination with 5-FU in a human pancreatic cancer model;
DEP docetaxel & DEP cabazitaxel outperformed both gemcitabine & Abraxane in a human pancreatic cancer model; and
A range of DEP radiopharmaceutical and other DEP candidates have been made and are currently undergoing testing in a variety of models.
Starpharma concluded the half-year in a strong financial position with a cash balance of $44.4 million, which does not include the $4.0M FY18 R&D tax incentive expected to be received after 31 December 2018. The net loss after tax for the half-year of $7.3 million (Dec 2017: $6.2 million) reflects investment across the VivaGel and DEP portfolio, including DEP docetaxel, DEP cabazitaxel, and DEP irinotecan. Expenditure includes an increased investment in commercialisation, regulatory and operating costs associated with the US VivaGel BV licence and the preparation for product launch in a number of territories.

Starpharma’s CEO, Dr Jackie Fairley, commented: "We achieved several important milestones in the VivaGel portfolio during the half-year, including signing a US licence for VivaGel BV with ITF Pharma, Inc. We were clearly surprised and disappointed by the FDA’s request for confirmatory data and we are working with expert FDA consultants to expedite this process. In non-US territories, launch activities are in the final stages as we approach the launch of VivaGel BV in Australia and Europe (1HCY19). We also continue to work closely with our partner, Mundipharma, on further registrations to support launches in several other regions."

Commenting on the DEP drug delivery portfolio, Dr Fairley said: "We’re pleased to see efficacy signals once again in both our DEP clinical trials as well as a notable lack of bone marrow toxicity and other common side effects. An abundance of positive data from the DEP platform, both preclinical and clinical, continues to build amid partnered program discussions with a number of multinational and US pharmaceutical companies. Our first partnered program with AstraZeneca for AZD0466 is expected to commence clinical trials this year and preparations at AstraZeneca for this activity continue with priority. This partnered program is just one example of the value that can be generated from our unique DEP platform."

Dr Fairley concluded: "We expect to announce a number of key milestones throughout 2019, in addition to the launch of VivaGel BV in Australia and Europe, and regulatory progress across a range of markets, including the US; launch of the VivaGel condom in Japan; regulatory approval of the VivaGel condom in other regions; and progress across internal and partnered DEP programs including commencement of the DEP irinotecan and AZD0466 clinical trials."

On February 27, 2019 Oncolytics Biotech Inc. (NASDAQ: ONCY) (TSX: ONC), currently developing pelareorep, an intravenously delivered immuno-oncolytic virus, reported the publication of an abstract demonstrating a biomarker for predicting clinical response in patients treated with pelareorep (Press release, Oncolytics Biotech, FEB 27, 2019, View Source [SID1234533792]). This analysis was conducted in patient samples from REO 024; a study of pelareorep and Keytruda in combination with chemotherapy in patients with second-line pancreatic cancer. Detailed results will be presented at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting taking place March 30 through April 3 in Atlanta, Georgia.

”With a simple blood draw, this biomarker data allows physicians to understand which patients are likely to respond to treatment, allowing for the design of clinical studies that are cheaper, faster and more likely to succeed,” said Dr. Matt Coffey, President and CEO of Oncolytics Biotech. ”Our biomarker data that we will present at AACR (Free AACR Whitepaper) is immediately applicable to future clinical studies. Investigators should now be able to predict which patients will respond to pelareorep in combination with a checkpoint inhibitor. This biomarker will be evaluated in our clinical studies with checkpoint inhibitors, including both of our multiple myeloma studies, the AWARE-1 breast cancer study, and importantly, in the same setting this data was produced, our phase two second-line pancreatic study in combination with Keytruda.”

"Using patient blood samples from our REO 024 study in second line pancreatic cancer, T cell receptor sequencing was performed with Adaptive Biotechnologies’ immunoSEQ Assay to measure the diversity or clonality of the T cell population,” said Dr. Rita Laeufle, CMO of Oncolytics Biotech. ”Results from this analysis demonstrate that higher clonality after one three-week cycle of treatment can identify patients likely to respond to combination treatment of pelareorep and a checkpoint inhibitor.”

The results suggest that those patients with a statistically significant change in their T cell population demonstrate a clinical benefit from pelareorep treatment. High T cell clonality correlates with progression free survival at baseline (HR=0.05, p=0.01). Moreover, high clonality correlates with overall survival at both baseline (HR=0.124, p=0.01) and after one cycle of treatment (HR=0.08, p=0.01). This research highlights the potential utility of measuring T cell clonality as a predictive and prognostic biomarker of pelareorep therapy.

The abstract, authored by Dr. Grey Wilkinson, a translational scientist at Oncolytics Biotech, and his colleagues, in collaboration with Northwestern University, UT Health San Antonio and Adaptive Biotechnologies, can be found online at View Source!/6812/presentation/4866. Full details from the poster presentation will be announced after it is presented.

52 patients have been dosed in the trial which included two separate patient groups. The company completed the targeted enrollment of 40 patients in the primary enrollment population, constituting patients who are naïve to prior ipilimumab treatment in the metastatic setting. This patient population mirrors the enrollment for the ILLUMINATE-301 phase 3 pivotal trial. The secondary exploratory enrollment population targeted up to 20 patients who had prior ipilimumab treatment in the metastatic setting.

The ILLUMINATE-204 trial is a multi-center trial being conducted at 10 sites throughout the United States.

The company is currently enrolling ILLUMINATE-301, a global, multi-center, randomized Phase 3 trial that compares effectiveness and safety between two treatment groups: tilsotolimod combined with ipilimumab versus ipilimumab given alone. This trial is being conducted at up to 100 centers with a target enrollment of 308 patients. Enrollment remains on track and is expected to be completed in the 4th quarter of 2019.

The company also recently received notice from the U.S. Food and Drug Administration that the company can proceed to implement the ILLUMINATE-206 clinical trial under a new Investigational New Drug (IND) Application. The ILLUMINATE-206 trial will test the safety and effectiveness of tilsotolimod in combination with ipilimumab and nivolumab in treating patients with Squamous Cell Carcinoma of the Head and Neck (SCCHN) and Microsatellite Stable Colorectal Cancer (MSS-CRC). The ILLUMINATE-206 trial is expected to initiate in the second quarter of 2019.

"We made tremendous progress with the clinical development of tilsotolimod in the second half of 2018, and enrollment in the phase 3 study in patients with melanoma progressing on PD-1 therapy is tracking to complete by the end of 2019." stated Joanna Horobin, M.B. Ch.B, Idera’s Chief Medical Officer. "Oncologists are enthusiastic to extend the use of tilsotolimod to potentially improve the outcome of immuno-therapy for other patient populations, such as head and neck cancer, and in microsatellite stable CRC where so far immunotherapy outcomes have not been optimal."

As a reminder, the company provided an interim data update from the ILLUMINATE-204 trial in December 2018.

Summary of ILLUMINATE-204 Key Findings from the December 2018 Update:

37 patients dosed with 8 mg of tilsotolimod in combination with ipilimumab were evaluated for the December 2018 update;
All 37 patients were evaluable for safety;
The combination regimen continues to be generally well tolerated. 9/37 subjects (24.3%) had immune-related toxicities indicating that tilsotolimod + ipilimumab does not appear to add immune-related toxicity versus ipilimumab alone;
Injection-related toxicities were grade 1-2 transient fever and flu-like symptoms lasting <48 hours;
34 patients were evaluable for efficacy;
Responses, including 3 Complete Responses (CR), were observed in 11 of the 34 evaluable patients (32.4%);
Duration of response ranges from > 1 month to > 30 months, with 36% of responses ongoing at the time of the report;
Per RECIST v1.1, the Overall Response Rate (ORR) is 29.4%; one patient with an unconfirmed Partial Response (uPR) at the end of treatment assessment progressed due to a new lesion at the 3-month follow-up disease assessment;
Overall, 26 patients out of 34 evaluable for efficacy (76.5%) experienced disease control (CR, PR, or Stable Disease [SD]);
Analysis of spider plots show tumor shrinkage in both injected and uninjected lesions, indicating an abscopal effect;
Responding subjects include one patient with mucosal melanoma and one patient with acral melanoma, two forms of melanoma that are particularly difficult to treat; and
Importantly, 2 of 5 patients with prior ipilimumab experience achieved responses, further demonstrating a signal that tilsotolimod has the potential to help overcome prior ipilimumab resistance.
Additionally:

A RECIST v1.1 PR of > 2.5 years is ongoing in 1 patient treated with tilsotolimod 4 mg in combination with ipilimumab; and
A RECIST v1.1 CR of > 1 year is ongoing in 1 patient treated with tilsotolimod 16 mg in combination with pembrolizumab.
About Tilsotolimod (IMO-2125)
Tilsotolimod is a TLR 9 agonist that received Fast Track Designation from the US Food and Drug Administration (FDA) in 2017 for the treatment of anti-PD-1 refractory melanoma, in combination with ipilimumab as well as orphan drug designation from the FDA for the treatment of melanoma Stages IIb to IV. It signals the immune system to create and activate cancer-fighting cells (T-cells) to target solid tumors. Currently approved immuno-oncology treatments, specifically check-point inhibitors, work for some but not all, as many patients’ immune response is missing or weak and thus they do not benefit from the checkpoint therapy. Intratumoral injections with tilsotolimod are designed to selectively enable the tumor-specific T-cells to recognize and attack cancers that remained elusive and unrecognized by the immune system exposed to checkpoint inhibitors alone, while limiting toxicity or impact on healthy cells in the body.

About ILLUMINATE-301
The ILLUMINATE-301 study (2125-MEL-301) is for patients who have metastatic melanoma for whom treatment with an anti-PD-1 drug like Keytruda (pembrolizumab) or Opdivo (nivolumab) has failed. ILLUMINATE-301 is a global, multi-center, randomized Phase 3 study that compares the effectiveness and safety between two treatment groups: IMO-2125 combined with ipilimumab (Yervoy) versus ipilimumab given alone.

For additional details about ILLUMINATE-301, please go to clinicaltrials.gov and search for study identifier NCT03445533.

About ILLUMINATE-204
The ILLUMINATE-204 study (2125-204) is for patients who have metastatic melanoma for whom treatment with an anti-PD-1 drug like Keytruda** (pembrolizumab) or Opdivo* (nivolumab) has failed. ILLUMINATE-204 is a multi-center, two-arm Phase 1/2 study that tests the safety and effectiveness of tilsotolimod in combination with either ipilimumab (Yervoy) or pembrolizumab (Keytruda) for the treatment of patients with anti-PD-1 refractory metastatic melanoma.

For additional details about ILLUMINATE-204, please go to clinicaltrials.gov and search for study identifier NCT02644967.

About ILLUMINATE-206
The ILLUMINATE-206 study (2125-206) is a Phase 2 multi-center, multi-cohort study of intratumoral tilsotolimod in combination with nivolumab and ipilimumab in patients with Squamous Cell Carcinoma of the Head and Neck (SCCHN) who are either immunotherapy naïve and immunotherapy refractory and immunotherapy naïve patients with Microsatellite Stable Colorectal Cancer (MSS-CRC). The trial is expected to open for enrollment in the second quarter of 2019.

About Metastatic Melanoma
Although melanoma is a rare form of skin cancer, it comprises over 75% of skin cancer deaths. The American Cancer Society estimates that there were approximately 76,000 new invasive melanoma cases and 10,000 deaths from the disease in the USA in 2016. Additionally, according to the World Health Organization, about 132,000 new cases of melanoma are diagnosed around the world every year.

Full Year Financial Results

Cash, cash equivalents and short-term investments totaled $436.1 million as of December 31, 2018, compared to $374.1 million as of December 31, 2017.

Revenue was $59.5 million for the year ended December 31, 2018, compared to $71.6 million for the year ended December 31, 2017. The $12.1 million decrease is largely attributable to the recognition of $14.0 million in milestone revenue in 2017 from AbbVie (net of a $1.0 million license fee paid to SGEN) as a result of completion of certain milestones under the CD71 Agreement, the recognition of a $10 million milestone in 2017 from BMS related to the IND filing for BMS-986249, the recognition of $6.5 million in revenue in 2017 related to the delivery of the ImmunoGen 2017 License to ImmunoGen in connection with the ImmunoGen Research Agreement, a decrease of $4.5 million in the amortization of deferred revenue under the ImmunoGen Research Agreement which concluded on June 30, 2018, and a decrease of $0.5 million in revenues from Pfizer as a result of Pfizer terminating our Research Collaboration, Option and License Agreement in March 2018. These decreases were partially offset by the recognition of $11.7 million of revenue in 2018 related to the milestone payment of $21.0 million from AbbVie (net of the associated $4.0 million sublicense fee to SGEN) for the achievement of the IND filing success criteria under the CD71 Agreement, an increase of $7.9 million in amortization of deferred revenue in 2018 related to the $200.0 million upfront payment received in the second quarter of 2017 as a result of the extension of the BMS collaboration, and an increase of $3.6 million of revenue from Amgen under the Amgen Agreement entered into in September 2017.

Research and development expenses increased by $11.6 million during the year ended December 31, 2018 compared to the corresponding period in 2017. The increase was primarily attributed to an increase in lab services of $10.0 million and $12.3 million in clinical trial expenses related to CX-072, CX-2009 and CX-2029 Phase 1/2 clinical development. There was also an increase of $10.5 million in personnel related expenses; $1.2 million increase in allocation of information technology and facilities related expenses; $0.9 million in lab supplies and $0.7 in consulting expenses. These amounts were largely offset by the recognition, during the third quarter of 2017, of $10.7 million of non-cash in-process research and development expense; $12.1 million of sublicense fees payable to the University of California, Santa Barbara, as a result of both the $200 million upfront payment made by BMS in connection with the expanded collaboration and the Amgen Agreement and a $1.0 million sublicense fee to ImmunoGen upon commencement of enrollment of Phase 1/2 and first patient dosing in the clinical trial for CX-2009 in the second quarter of 2017.

General and administrative expenses increased by $7.9 million during the year ended December 31, 2018 compared to the corresponding period in 2017. This increase was largely attributed to an increase of $5.6 million in personnel related expenses due to increases in headcount, and $2.3 million for various consulting and other services.
