Idera Pharmaceuticals Reports Third Quarter 2018 Financial Results and Provides Corporate Update

–  Company to Provide ILLUMINATE 204 Data Update in the First Half of December 2018 –
–  Cash runway into first quarter of 2020 –

EXTON, Pa., Nov. 06, 2018 (GLOBE NEWSWIRE) — Idera Pharmaceuticals, Inc. (NASDAQ: IDRA), a clinical-stage biopharmaceutical company focused on the development, and ultimately the commercialization, of therapeutic drug candidates for both oncology and rare disease indications characterized by small, well-defined patient populations with serious unmet medical needs, today reported its financial and operational results for the third quarter ended September 30, 2018.

“The third quarter of 2018 was marked by continued focus and execution throughout our company advancing the tilsotolimod ILLUMINATE 301 trial toward approval in our lead indication in anti-PD-1 refractory or relapsed metastatic melanoma. We also made significant progress framing our plans to expand the development of tilsotolimod to additional tumor types,” stated Vincent Milano, Idera’s Chief Executive Officer. 

“Over these past several years, through all of the preclinical studies, translational data collections and ultimately our early clinical experiences, it’s becoming clearer to us that the potential utility of tilsotolimod is not limited to melanoma and is certainly not limited by the location or type of tumor,” continued Milano. “We look forward to providing our next clinical update from the ILLUMINATE 204 trial in the first half of December as well as laying out our expansion plans for the program in the beginning of 2019.”

“The majority of our company’s focus is and will remain towards maximizing the opportunity with, and more importantly, the number of patients that can benefit from, tilsotolimod. At the same time, we recognize and embrace the concept of continuing to build Idera for the future. To that end, we will continue to be aggressive in our pursuit of additional assets to further drive value for our shareholders, and more importantly, meet the needs of patients suffering from rare diseases with serious unmet needs.”

Clinical Development Program Updates:

ILLUMINATE (tilsotolimod) Clinical Development

ILLUMINATE 301 – Randomized Phase 3 trial of intratumoral tilsotolimod in combination with ipilimumab versus ipilimumab alone in patients with PD-1 refractory/relapsed metastatic melanoma:

  • Trial initiated in the first quarter of 2018;
  • 42 of the planned up to 110 sites across 12 countries have been activated for the randomization of patients into the trial;
  • ILLUMINATE 301 Trials in Progress (TiPS) presentation on trial design featured at the 2018 Congress of the European Society of Medical Oncology (ESMO);
  • Planned enrollment of approximately 300 patients with Overall Response Rate (“ORR”) and Overall Survival as primary endpoints; and
  • U.S. Food and Drug Administration granted Fast Track Designation in fourth quarter of 2017 for tilsotolimod in combination with ipilimumab for the treatment of patients with unresectable or metastatic melanoma following failure of PD-1 inhibitor treatment.

ILLUMINATE 204 – Phase 1/2 trial of intratumoral tilsotolimod in combination with either ipilimumab or pembrolizumab in patients with PD-1 refractory/relapsed metastatic melanoma:

Ipilimumab Combination Arm – Phase 2 Recruitment Ongoing

  • Enrollment continues at 10 U.S. clinical trial sites;
  • Two additional sites planned for initiation in November 2018;
  • ILLUMINATE 204 Trial Data update presented at ESMO 2018 demonstrated both abscopal effect as well as the potential of intratumoral tilsotolimod to overcome known resistance mechanisms to ipilimumab treatment as a monotherapy.
  • Earlier this year at the American Society of Clinical Oncology (ASCO) Annual Meeting, the company presented clinical efficacy and safety data from the first 21 evaluable patients demonstrating:
    • Confirmed RECIST v1.1 responses (including 2 Complete Responses [CR]) were observed in 8 of these 21 subjects (38.1%);
    • Overall 15 patients out of 21 evaluable for efficacy (71.4%) experienced disease control (CR, PR, or SD);
    • The combination regimen was generally well tolerated. 6/26 subjects (23%) had immune-related toxicities indicating that IMO-2125 + ipilimumab does not appear to add toxicity versus ipilimumab alone;
    • Injection-related toxicities were grade 1-2 transient fever and flu-like symptoms lasting <48 hours;
    • 15/26 patients (57.7%) with lesions accessible only by image-guided injection (5 deep visceral lesions and 10 lymph nodes) were included; and
  • The company plans to provide a data update on up to 35 evaluable patients in first half of December 2018.

Pembrolizumab Combination Arm – Phase 1 Dose Escalation Ongoing

  • Enrollment in the last dosing cohort (32 mg) ongoing with one patient remaining to complete enrollment (priority enrollment has been towards the ipilimumab combination arm of ILLUMINATE 204).
  • One patient in the cohort testing 16mg intratumoral tilsotolimod in combination with pembrolizumab continues on study with a confirmed complete response (CR).

ILLUMINATE 101 – Phase 1b trial of intratumoral tilsotolimod monotherapy in patients with refractory solid tumors:

  • Completed enrollment in all four dose ranging cohorts; 41 patients enrolled;
  • Continuing enrollment into the refractory melanoma cohort at the 8 mg dose of intratumoral tilsotolimod as monotherapy;
  • Translational data continues to be collected, analyzed and is planned to be submitted for presentation at a medical oncology conference in 2019.

Investigator Sponsored Trials (IST)
Idera is supportive of several Investigator Sponsored Trials and continues to evaluate additional proposals:

  • A Phase 1/2 open label study of intratumoral tilsotolimod in combination with intratumoral ipilimumab and IV nivolumab in a protocol open to multiple tumor types including non-small cell lung cancer (NSCLC), melanoma, squamous cell carcinoma of the head and neck and urothelial carcinoma. The principal investigator initiating this trial is Aurélien Marabelle, MD, PhD, Clinical Director of the Cancer Immunotherapy Program at Institut Gustave Roussy, Villejuif, France; and
  • A Phase 2 placebo-controlled study of intradermal administration of tilsotolimod in patients with T3/T4 primary melanoma scheduled to undergo a combined re-excision and sentinel node biopsy (SNB) procedure. The principal investigators initiating this trial are Bas Koster, MD and Tanja de Gruijl, PhD at The VU University Medical Center, Amsterdam, the Netherlands.

Financial Results
Third Quarter Results
Net loss applicable to common stockholders for the three months ended September 30, 2018 was $11.6 million, or $0.43 per basic and diluted share, compared to net loss applicable to common stockholders of $14.5 million, or $0.78 per basic and diluted share, for the same period in 2017. Revenue in each of the three months ended September 30, 2018 and 2017 was nominal. Research and development expenses for the three months ended September 30, 2018 totaled $8.9 million compared to $10.9 million for the same period in 2017. General and administrative expense for the three months ended September 30, 2018 totaled $4.0 million compared to $3.9 million for the same period in 2017. Merger-related costs, net for the three months ended September 30, 2018 amounted to a net credit of $3.8 million and was comprised of a $6.0 million fixed expense reimbursement received in connection with the termination of the company’s proposed merger with BioCryst Pharmaceuticals, Inc., which was terminated in July 2018; partially offset by $2.2 million of expenses incurred in connection with the transactions contemplated by the related merger agreement. No such costs were incurred during 2017. Restructuring costs for the three months ended September 30, 2018 totaled $3.0 million and are a result of our decision in July 2018 to wind-down our discovery operations, reduce the workforce in Cambridge, Massachusetts that supported such operations, and close our Cambridge facility. No such costs were incurred during 2017.

As of September 30, 2018, the company’s cash and cash equivalents totaled $82.5 million.  The company currently anticipates that, based on its current operating plan, its existing cash and cash equivalents will be sufficient to fund company operations into the first quarter of 2020.
