"We made considerable progress in the third quarter, particularly in the development program for CDX-1140, our promising antibody targeted to CD40," said Anthony Marucci, Co-founder, President and Chief Executive Officer of Celldex Therapeutics. "We have completed four of the potential eight monotherapy dose levels in the ongoing Phase 1 study and remain encouraged by the safety and biological profile we have observed to date. We look forward to sharing interim data at the SITC (Free SITC Whitepaper) Annual Meeting later this week. During the third quarter, we also began enrolling patients in a combination cohort of CDX-1140 with our dendritic cell mobilizer, CDX-301. We are very interested to explore the potential of CDX-1140 in the presence of greater dendritic cell activity."

"Additionally, we are nearing completion of enrollment to the first stage of the Phase 2 study of CDX-3379 in advanced head and neck squamous cell cancer and anticipate data from this portion of the study in the first quarter of 2019," continued Marucci. "We are also advancing several preclinical programs that we believe can play an important role in enhancing the immune system’s response to cancer, including CDX-0159, our TAM program targeting Tyro3, AXL and MerTK, and our growing bispecific antibody program."

Recent Highlights:

Enrollment continues in the Phase 1 dose-escalation study of CDX-1140 in solid tumors. Interim data from the ongoing study have been accepted for presentation on Friday, November 9, 2018 at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) Annual Meeting. This study is designed to enroll up to 150 patients with recurrent, locally advanced or metastatic solid tumors and was recently amended to also include B-cell lymphomas. CD40 has long been an important target for immunotherapy, as it plays a critical role in the activation of innate and adaptive immune responses; however, effectively balancing systemic dosing and safety has proven challenging to date for CD40-activating therapeutics. CDX-1140 is a unique, potent CD40 agonist that Celldex believes has the potential to successfully balance systemic doses for good tissue and tumor penetration with an acceptable safety profile. Data to date from the four completed dosing cohorts (0.01, 0.03, 0.09 and 0.18 mg/kg) suggest that CDX-1140 is exhibiting a desirable safety profile and demonstrating early signs of biological activity based on biomarker analysis. The fifth monotherapy cohort at 0.36 mg/kg is currently being enrolled, along with the combination therapy cohort of CDX-1140 (0.09 mg/kg) with CDX-301 which was initiated in late August. CDX-301 is a dendritic cell growth factor that will be used as a priming agent to potentially increase the number of cells available to respond to CDX-1140. In addition, Celldex is evaluating the potential for combination with varlilumab, especially in lymphomas which co-express CD40 and CD27 receptors.

Enrollment is nearing completion in the first stage of the Phase 2 study (n=13) of CDX-3379 in advanced head and neck squamous cell cancer in combination with Erbitux in Erbitux-resistant patients who have been previously treated with or are ineligible for checkpoint therapy. According to the study’s Simon two-stage design, if at least one patient achieves an objective response in the first stage, enrollment may progress to the second stage. While a confirmed partial response has been documented, Celldex will wait to review the full data set before making decisions on future development, as a number of patients are still undergoing treatment and are not yet eligible for response evaluation.

Data from the glioblastoma cohort in the Phase 1/2 study of varlilumab and Opdivo have been accepted for presentation on Saturday, November 17, 2018 at the Society for Neuro-oncology (SNO) Annual Meeting.

As previously disclosed, on May 29, 2018, Celldex received written notice from the Listing Qualifications department of the Nasdaq Stock Market indicating that the Company was not in compliance with the $1.00 minimum bid price requirement for continued listing on the Nasdaq Global Market. As is standard, the Company was afforded 180 days to regain compliance. Unless Celldex regains compliance with the minimum bid requirement by November 26, 2018 (the 180th day), the Company plans to apply to transfer to the Nasdaq Capital Market. Assuming Celldex’s application is accepted, the proposed transition should be seamless for Celldex shareholders and should allow the company an additional 180-day period in which to regain compliance. If Celldex is unable to regain compliance with the minimum bid price requirement, the Company may implement a reverse stock split to maintain its listing, a measure that was approved by shareholders at the Company’s 2018 Annual Meeting.
Third Quarter 2018 and First Nine Months 2018 Financial Highlights and 2018 Guidance

Cash Position: Cash, cash equivalents and marketable securities as of September 30, 2018 were $105.6 million compared to $114.0 million as of June 30, 2018. The decrease was primarily driven by third quarter cash used in operating activities of approximately $14.4 million, of which $3.2 million were glembatumumab vedotin-related payments, partially offset by the receipt of $5.5 million from sales of common stock under the Cantor agreement. Celldex expects that it will make an additional $2.0 million in glembatumumab vedotin-related payments related to the discontinuation of that program. At September 30, 2018, Celldex had 168.6 million shares outstanding.

Revenues: Total revenue was $0.9 million in the third quarter of 2018 and $7.8 million for the nine months ended September 30, 2018, compared to $3.9 million and $9.3 million for the comparable periods in 2017. The decrease in revenue was primarily due to lower contract revenue from the International AIDS Vaccine Initiative.

R&D Expenses: Research and development (R&D) expenses were $11.9 million in the third quarter of 2018 and $55.2 million for the nine months ended September 30, 2018, compared to $21.9 million and $72.7 million for the comparable periods in 2017. The decrease in R&D expense was primarily due to lower clinical trial, contract manufacturing and personnel expenses.

G&A Expenses: General and administrative (G&A) expenses were $3.7 million in the third quarter of 2018 and $14.9 million for the nine months ended September 30, 2018, compared to $5.3 million and $19.1 million for the comparable periods in 2017. The decrease in G&A expenses was primarily due to lower personnel and marketing expenses.

Changes in Fair Value Remeasurement of Contingent Consideration: Gain on the fair value remeasurement of contingent consideration related to the Kolltan acquisition was $6.9 million in the third quarter of 2018 and $28.0 million for the nine months ended September 30, 2018, primarily due to discontinuation of the glembatumumab vedotin and CDX-014 programs and updated assumptions for the varlilumab and anti-KIT programs.

Net Loss: Net loss was $7.2 million, or ($0.04) per share, for the third quarter of 2018, and $141.8 million, or ($0.94) per share, for the nine months ended September 30, 2018, compared to a net loss of $26.4 million, or ($0.20) per share, for the third quarter of 2017 and $89.2 million, or ($0.71) per share, for the nine months ended September 30, 2017.

Financial Guidance: Celldex believes that the cash, cash equivalents and marketable securities at September 30, 2018, combined with the anticipated proceeds from future sales of common stock under the Cantor agreement, are sufficient to meet estimated working capital requirements and fund planned operations through 2020. This could be impacted if Celldex elects to pay Kolltan contingent milestones, if any, in cash.

Sensei Biotherapeutics Presents Clinical Trial Data Demonstrating SNS-301 Induces Rapid and Robust Antigen-specific Immune Responses at the Society for Immunotherapy of Cancer’s 33rd Annual Meeting

On November 6, 2018 Sensei Biotherapeutics, Inc., a clinical-stage biopharmaceutical company developing precision immuno-oncology therapies, reported that clinical and immunological data from the Phase 1 clinical trial of SNS-301 will be highlighted in a poster presentation at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper)’s (SITC) (Free SITC Whitepaper) 33rd Annual Meeting, to be held November 9-11, 2018 in Washington, D.C (Press release, Sensei Biotherapeutics, NOV 6, 2018, View Source [SID1234530933]). Data showed rapid and significant antigen-specific B-cell and T-cell responses induced by SNS-301, a first-in-class cancer immunotherapy targeting human aspartate β-hydroxylase (ASPH), a novel tumor-specific embryonic antigen.

"These data clinically confirm the immunogenicity and mechanism of action of SNS-301, as we see strong, ASPH-targeted activation of the immune system in patients who received the immunotherapy. Taken together, the data indicate that SNS-301 is capable of overcoming central immune tolerance. We plan to target ASPH with both cancer vaccines and cell therapies to benefit different patient populations," said John Celebi, President and Chief Executive Officer of Sensei Biotherapeutics. "Based on these encouraging results, we look forward to initiating a Phase 2 trial for SNS-301 in various hematological malignancies and solid tumors in early 2019."

Twelve patients with biochemically recurrent prostate cancer who were screened for ASPH using Sensei’s proprietary companion diagnostic were treated with SNS-301 in the Phase 1, multi-center, proof-of-concept study. SNS-301 was administered every 21 days via intradermal injection using a fixed dose-escalation schema through which patients received between 8 and 23 doses at three different dose ranges, and the recommended Phase 2 dose was determined based on the immunogenicity data and changes seen in prostate specific antigen (PSA) doubling times at the three evaluated doses. Highlights of the immunogenicity data from the SNS-301 Phase 1 study presented at SITC (Free SITC Whitepaper) include:

Natural Killer (NK) cell levels in patients treated with SNS-301 were higher than NK cell levels in healthy donors, indicating activation of the innate immune system.
All patients evaluable for immune profiling experienced dose-dependent, ASPH-specific immune responses including B-cell, T-cell and antibody responses.
Increases in activated interferon gamma (IFN-γ) releasing T cells were demonstrated, and both ASPH-specific CD4+ helper T cells and CD8+ cytotoxic T cells showed dose-dependent activation over the first six cycles of SNS-301 dosing with peak responses often occurring after only three or four doses.
An average of eight to ten-fold increase in the percentage of ASPH-specific CD8+ T cells was observed post-treatment, compared to baseline measurements.
Anti-ASPH antibody titers increased in a dose-dependent manner over the first four to six cycles (80-120 days) after administration of SNS-301. This increase in antibody response correlated with concomitant increases in the percentages of ASPH-specific B cells, as measured by flow cytometry.
An average five to seven-fold increase in the percentage of ASPH-specific B-cell responses was observed post-treatment, compared to baseline measurements.
Eight out of the twelve patients (67%) achieved improvements in PSA doubling time and/or absolute PSA level, leading to decreased PSA velocity and suggesting a disease stabilizing effect of SNS301.
Based on evaluation of the three different dose ranges (2 x 1010, 1 x 1011, 3 x 1011 particles), immune responses occurred more rapidly at the two higher doses, as compared to the lower dose. Immunologic efficacy generally correlated with biochemical responses in these patients.
In the Phase 1 study, SNS301 was well tolerated with a favorable safety profile at all three dose levels with no dose-limiting toxicities or grade 4 or 5 adverse events.

About SNS-301
SNS-301 is a first-in-class cancer immunotherapy targeting human aspartate β-hydroxylase (ASPH), a cell surface enzyme that is normally expressed during embryonic development. Following embryonic development, the protein is no longer expressed in healthy adults. Expression of ASPH is uniquely upregulated in more than 20 different types of cancer and is related to cancer cell growth, cell motility and invasiveness. ASPH alters signaling that occurs through the Notch pathway and its expression levels in various tumors are inversely correlated with disease prognosis. SNS-301 is a bio-engineered, inactivated bacteriophage virus expressing a fusion protein of native bacteriophage gpD (gene product D) and a selected domain of ASPH. SNS-301 is designed to overcome immune tolerance and induce robust and durable ASPH-specific humoral and cellular responses. SNS-301 is paired with a companion diagnostic to ensure appropriate patient selection and is delivered easily through an intradermal injection to aid in generating robust immune response.
