Press Release

HAMPTON, N.J., May 09, 2017 (GLOBE NEWSWIRE) -- Celldex Therapeutics, Inc. (NASDAQ:CLDX) today reported business and financial highlights for the first quarter ended March 31, 2017.

"In the first quarter of 2017, Celldex made considerable progress across our pipeline," said Anthony Marucci, Co-founder, President and Chief Executive Officer of Celldex Therapeutics. "We continue to expect enrollment completion in our ongoing study of glembatumumab vedotin in triple negative breast cancer by the end of September, and we recently completed enrollment in the Phase 2 glembatumumab vedotin plus varlilumab combination cohort in checkpoint-refractory metastatic melanoma. Glemba's target, gpNMB, is highly expressed in melanoma and triple negative breast cancer, among others, and is associated with more aggressive disease. We believe taking an antibody-drug conjugate approach to targeting gpNMB generates a potent cytotoxic effect within the tumor and its environment and may ultimately result in improved outcomes for patients."

"We also look forward to presenting data from two programs in oral sessions at ASCO in June—the Phase 2 single-agent study of glembatumumab vedotin in metastatic melanoma and the Phase 1 combination study of varlilumab and Opdivo."

Recent Highlights

• Continued progress in METRIC enrollment: Celldex continues to expect that enrollment will be completed by the end of September 2017. METRIC is a Phase 2b randomized study of glembatumumab vedotin in patients with metastatic triple negative breast cancers that overexpress gpNMB.
  
  
• Single-agent glembatumumab vedotin Phase 2 study in checkpoint-refractory metastatic melanoma accepted for oral presentation at ASCO: Updated data from the single-agent cohort of the Phase 2 study will be presented in an oral presentation at the 2017 American Society of Clinical Oncology (ASCO) Annual Meeting in June. Enrollment recently completed in the glembatumumab vedotin and varlilumab arm, with data from this portion of the study expected in the fall of 2017. Enrollment continues in the glembatumumab vedotin plus checkpoint inhibitor (Opdivo^® or Keytruda^®) arm in patients who failed prior checkpoint therapy, a population with limited treatment options.
  
  
• Phase 1 varlilumab/Opdivo^® study accepted for oral presentation at ASCO: Updated data from the Phase 1 portion of the varlilumab and Opdivo study will be presented in an oral presentation at the 2017 ASCO Annual Meeting in June. The Phase 2 portion of the combination study includes cohorts in colorectal cancer, ovarian cancer, head and neck squamous cell carcinoma, renal cell carcinoma and glioblastoma, and is currently enrolling patients. The Company plans to complete enrollment across all cohorts in the Phase 2 portion of the study in the first quarter of 2018 and will work with Bristol-Myers Squibb to present data from the study at a future medical meeting. Data from the Phase 1 single-agent study of varlilumab in solid tumors were recently published in the Journal of Clinical Oncology.
   
• Phase 1 study of CDX-0158 continues to enroll patients: This dose escalation study in patients with advanced refractory gastrointestinal stromal tumors (GIST) and other KIT-positive tumors is designed to determine the maximum tolerated dose, recommend a dose for further study and characterize the safety profile of CDX-0158. Data from the study continue to be expected by year-end 2017.
  
  
• CDX-3379 advancing to Phase 2: The Company is currently finalizing plans for advancement into a Phase 2 study in combination with cetuximab in patients with cetuximab-resistant advanced head and neck squamous cell carcinoma.
   
• Enrollment ongoing in Phase 1 study of CDX-014: The study in advanced renal cell carcinoma (clear cell and papillary) is designed to determine the maximum tolerated dose and to recommend a dose level for further study. Celldex continues to expect the Phase 1 dose-escalation portion of the study will complete enrollment by year-end 2017.
  

First Quarter 2017 Financial Highlights and Updated 2017 Guidance

Cash position: Cash, cash equivalents and marketable securities as of March 31, 2017 were $167.0 million compared to $189.8 million as of December 31, 2016. The decrease was primarily driven by our first quarter cash used in operating activities of approximately $35.3 million which included a payment of $4.7 million in accrued amounts to a vendor of Kolltan. This obligation was assumed in the Kolltan acquisition. This decrease was partially offset by the receipt of $12.8 million from sales of our common stock under our Cantor agreement. At March 31, 2017, Celldex had 124.2 million shares outstanding.

Revenues: Total revenue was $1.5 million in the first quarter of 2017, compared to $1.3 million for the comparable period in 2016. The increase in revenue was primarily due to our clinical trial collaboration with Bristol-Myers Squibb and our research and development agreement with Rockefeller University.

R&D Expenses: Research and development (R&D) expenses were $25.8 million in the first quarter of 2017, compared to $27.4 million for the comparable period in 2016. The decrease in R&D expenses was primarily due to a decrease in Rintega product development expenses of $7.3 million, partially offset by increases in glembatumumab vedotin, CDX-0158 and CDX-3379 product development expenses of $1.8 million, $0.8 million and $0.7 million, respectively, and increases in personnel and facility costs related to the Kolltan acquisition.

G&A Expenses: General and administrative (G&A) expenses were $7.2 million in the first quarter of 2017, compared to $9.3 million for the comparable period in 2016. The decrease in G&A expenses was primarily due to a decrease in Rintega commercial planning costs of $2.0 million.

Loss on Fair Value Remeasurement of Contingent Consideration: In connection with the Kolltan Acquisition, we agreed to pay Kolltan's stockholders milestone payments of up to $172.5 million in the event that certain specified preclinical and clinical development milestones related to Kolltan's development programs and/or our development programs and certain commercial milestones related to Kolltan's drug candidates are achieved. These milestone payments may be made in cash, in shares of our common stock or a combination of both, subject to NASDAQ listing requirements and provisions of the merger agreement. The range of estimated milestone payments is from zero, if no milestones are achieved, to $172.5 million if all milestones are met. We record the fair value of these obligations to pay additional milestone payments using various estimates, including probabilities of success, discount rates and amount of time until the conditions of the milestone payments are met. The $3.4 million loss on fair value remeasurement of contingent consideration relates to an increase in the estimate of the fair value of the contingent consideration primarily due to changes in discount rates and the passage of time.

Net loss: Net loss was $34.3 million, or ($0.28) per share, for the first quarter of 2017, compared to a net loss of $34.7 million, or ($0.35) per share, for the comparable period in 2016.

Financial guidance: Celldex believes that the cash, cash equivalents and marketable securities at March 31, 2017 combined with the anticipated proceeds from future sales of our common stock under our Cantor agreement, are sufficient to meet estimated working capital requirements and fund planned operations through 2018; however, this guidance assumes we are able to and elect to pay future Kolltan contingent milestones, if any, in stock rather than cash.
