Highlights from the second quarter of 2017 and recent weeks include:

Revenue for the second quarter of 2017 increased 20% to $0.6 million from $0.5 million in the prior-year quarter;
Revenue for the first six months of 2017 increased 44% to $1.3 million from $0.9 million in the prior-year period;
Inclusion of CHEMOSAT in Dutch Health Authorities Guidelines (published in July 2017) as a recommended treatment for ocular melanoma liver metastases;
Reduction of an additional $9.5 million in principal amount related to the Company’s Convertible Notes, with $12.6 million in debt remaining; and
Raised $2.0 million through the issuance of Series B preferred shares to current noteholders, which are convertible into common shares at $0.153 per share.
Proposal on Effecting a Reverse Stock Split

Delcath recently filed a Definitive Schedule 14A detailing a proposed reverse stock split, subject to shareholder approval. Delcath needs the ability to issue common shares to fund operations, support clinical programs, service the amortization of its Convertible Note and explore alternative equity financing opportunities. However, the Company is currently at the maximum amount of authorized shares of common stock under its Certificate of Incorporation. Without a significant increase in available authorized shares, the Company is unable to access the $11.8 million of cash in the restricted accounts associated with the Convertible Notes issued last year, or to undertake any type of equity financing. The proposed reverse stock split will reduce the number of shares outstanding and provide Delcath with the flexibility to raise equity capital and support its important clinical trials and commercial efforts in Europe.

In addition, the reverse stock split will allow Delcath to regain compliance with NASDAQ Capital Markets continued-listing requirements, which provides liquidity and other important benefits to the Company and its investors. It is important to note that the floor price for the Convertible Note will adjust with the effected reverse stock split ratio to a minimum of $1.00. Delcath believes this will serve to support the stock price following a split and reduce future potential dilution related to the Convertible Notes.

For these reasons, the Company’s Board of Directors encourage all investors to support the proposed reverse stock split. Investors are encouraged to read the Company’s Definitive Schedule 14A in detail for full information regarding the proposed reverse stock split.

Management Commentary

"During the first half of 2017 we continued to advance our clinical development programs in ocular melanoma liver metastases (OM) and intrahepatic cholangiocarcinoma (ICC), while making steady progress with the ongoing commercialization of CHEMOSAT in Europe," said Jennifer K. Simpson, Ph.D., MSN, CRNP President and CEO of Delcath.

"Revenues for the second quarter of 2017 increased 20% from a year ago, demonstrating continued growing demand in our core markets. This increase is largely driven by the recent establishment of ZE diagnostic-related (DRG) reimbursement for CHEMOSAT in Germany. We continue to leverage this positive German reimbursement to support our efforts to obtain market access and payment in other markets such as the U.K. and the Netherlands, where there is growing interest in and use of CHEMOSAT. This is evidenced by the recent inclusion of CHEMOSAT in the Dutch Health Authorities treatment guidelines for ocular melanoma liver metastases, an important step toward eventual reimbursement coverage of CHEMOSAT in the Dutch market.

"Our primary focus continues to be on the clinical trials that comprise our Clinical Development Program (CDP), where we believe shareholder value ultimately lies. Our CDP consists of our FOCUS Phase 3 clinical trial of Melphalan/HDS in hepatic dominant OM (the FOCUS trial) and our intrahepatic cholangiocarcinoma (ICC) pivotal trial, which is scheduled to initiate enrollment by the end of 2017. The objective for our Phase 2 trial program in hepatocellular carcinoma (HCC) and ICC was to identify an efficacy signal worthy of further clinical investigation. This objective was met by the retrospective data collection performed by European investigators last year, which informed our development path for ICC. The U.S. Food and Drug Administration (FDA) endorsed that development pathway via a Special Protocol Assessment agreement negotiated earlier this year. With the Phase 2 trial program goals now met, we have terminated enrollment in the Phase 2 trials in order to devote available resources to the FOCUS Trial and the Phase 3 ICC pivotal trial.

"In March, we announced a SPA with the FDA for a pivotal trial of our Melphalan/HDS to treat ICC. As with the FOCUS trial, this SPA indicates that the trial design adequately addresses objectives that, if met, will support regulatory requirements for approval of Melphalan/HDS in the treatment of ICC. Since announcing the SPA we have been working with potential trial sites with the goal of initiating patient enrollment by the end of 2017. We are committed to executing this trial in a financially prudent manner and for this reason initiation of enrollment is contingent on effecting the reverse stock split as outlined in our consent proposal.

Enrollment in our FOCUS Phase 3 clinical trial of Melphalan/HDS in hepatic dominant OM (the FOCUS trial) has been proceeding more slowly than we expected. We have been continually reviewing the pace of recruitment in this study, and have discovered reluctance among some patients to participate as there was no mechanism to receive the experimental treatment at any time if they were randomized to the best alternative care arm. In a rare and deadly disease such as OM, it is not surprising that patients facing few treatment options would be reluctant to participate in a trial where there is no opportunity to receive the experimental treatment and where treatment is commercially available on a private pay basis in Europe. We are currently exploring options that will allow us to accelerate enrollment, which include adding new sites in both the U.S. and Europe. We have recently added several European clinical sites that are expected to provide increased patient flow starting this fall. We remain on track to conduct an interim safety analysis by the end of this year.

"Throughout the balance of 2017 we remain dedicated to advancing the clinical programs for our innovative Melphalan/HDS as well as to our commercialization efforts for CHEMOSAT in Europe. In order to support these important programs and create value, we need to enhance our capital structure, which begins with a favorable vote on the reverse stock split," concluded Dr. Simpson.

Second Quarter Financial Results

Revenue for the second quarter of 2017 was $0.6 million, an increase of 20% from $0.5 million for the second quarter of 2016. Selling, general and administrative expenses increased modestly to $2.5 million in the 2017 second quarter from $2.3 million in the prior-year quarter. Research and development expenses for the second quarter of 2017 increased to $2.5 million from $1.9 million in the prior-year quarter. Total operating expenses for the current quarter were $5.0 million compared with $4.2 million in the prior-year quarter.

The Company recorded a net loss for the three months ended June 30, 2017, of $2.0 million, a decrease of $4.7 million, or 70.9%, compared to a net loss of $6.7 million for the same period in 2016. This decrease in net loss is primarily due to a $9.6 million gain on the extinguishment of the June 2016 Series C Warrants which was offset by a $5.3 million increase in interest expense related to the convertible note, both non-cash items. Additionally, there was a $1.2 million decrease in the change in the fair value of the warrant liability, a non-cash item, offset by a $0.8 million increase in operating expenses primarily related to increased investment in our clinical trial initiatives.

Six Month Financial Results

Revenue for the first half of 2017 was $1.3 million, an increase of 44% from $0.9 million for the first half of 2016. Selling, general and administrative expenses in the first half of 2017 were approximately $4.9 million compared with $4.7 million in the prior-year period. Research and development expenses for the first six months of 2017 increased to $4.8 million from $3.3 million in the first six months of 2016. Total operating expenses for the first half of 2017 were $9.8 million compared with $8.0 million in the prior-year quarter.

The Company recorded a net loss for the six months ended June 30, 2017, of $13.3 million, an increase of $4.8 million, or 56.5%, compared to a net loss of $8.5 million for the same period in 2016. This increase in net loss is primarily due to a $13.7 million increase in interest expense primarily related to the amortization of debt discounts, offset by a $9.6 million gain on the extinguishment of the June 2016 Series C Warrants, both non-cash items. Additionally, there was a $1.8 million increase in operating expenses primarily related to increased investment in our clinical trial initiatives, offset by $0.4 million increase in gross profit and a $0.7 million increase in the change in the fair value of the warrant liability, a non-cash item.

Balance Sheet Highlights

As of June 30, 2017, Delcath had cash and cash equivalents of $1.8 million, compared with $4.4 million as of December 31, 2016. In addition, the Company has $12.9 million in restricted cash primarily related to the Convertible Notes issued in June 2016. During the six months ended June 30, 2017, the Company used $8.1 million of cash to fund operating activities. Assuming the Company is able to effect a reverse stock split as proposed in its recent consent solicitation statement filed with the SEC on July 26, 2017, management believes that its capital resources are adequate to fund operating activities through the end of 2017.

Recent Financial Transactions

In July 2017 Delcath issued two series of preferred stock (Series A Preferred Stock and Series B Preferred Stock) in transactions with holders of its Convertible Note. The Series A shares were issued to address a short-term valuation issue for common shares delivered to the Note holders to close an installment period. Through the Series A Preferred Shares placement, the Company was able to value the open installment shares such that the amount of debt remaining under the Convertible Note was reduced by $4.2 million. The Series B Preferred Shares, which are convertible to common shares at $0.153, allowed the Company to raise $2.0 million in unrestricted cash.

ChemoCentryx Reports Second Quarter 2017 Financial Results and Recent Highlights

"We’ve had a highly productive second quarter, activating many new sites in our avacopan Phase III ADVOCATE trial, which is producing a multiplier effect on patient enrollment," said Thomas J. Schall, Ph.D., President and Chief Executive Officer of ChemoCentryx. "Now we are launching a clinical trial for avacopan in a second indication, C3G, executing on our ‘pipeline in a drug’ strategy. We are also working with regulatory authorities on the design of a third trial, involving our CCR2 inhibitor, CCX140, intended to support registration in patients with Focal Segmental Glomerulosclerosis (FSGS)."

Recent Highlights

ChemoCentryx’s Phase III ADVOCATE trial of avacopan (formerly CCX168) for the treatment of ANCA-associated vasculitis is gaining momentum, with 143 sites activated in 18 countries across the world. The trial will test the safety and efficacy of avacopan following 12 months of treatment and will include approximately 300 patients. Enrollment rates per activated sites are exceeding projections, and the trial is on track to complete enrollment by mid 2018. In addition to testing the effect of avacopan on improving active vasculitis, the ADVOCATE trial will also test the effect of avacopan on preventing a recurrence of vasculitis, one of the major limitations of the current standard of care for this disease.

In May 2017, ChemoCentryx announced that the European Medicines Agency granted orphan medicinal product designation for avacopan in the treatment of patients with C3G, which followed shortly after orphan drug designation was granted for avacopan in the treatment of C3G by the U.S. Food and Drug Administration. The Company is launching a registration-supporting trial of avacopan in C3G patients. There is currently no approved therapy for C3G.
In June 2017, ChemoCentryx announced program advances in two oral presentations that were given during the 54th European Renal Association – European Dialysis and Transplant Association (ERA-EDTA) Congress in Madrid, which highlighted an additional potential clinical indication for avacopan and the potential for CCR2 inhibition in FSGS. The Company plans to launch a registration-supporting trial of CCR2 inhibitor CCX140 in patients with FSGS later this year.
Second Quarter 2017 Financial Results

Pro forma cash, cash equivalents, investments and remaining upfront commitments totaled $166.7 million at June 30, 2017.

Revenue was $8.9 million for the second quarter, compared to $2.8 million for the same period in 2016. The increase in revenues from 2016 to 2017 was due to; (i) amortization of the upfront license fee commitments from Vifor pursuant to the avacopan and CCX140 agreements, as well as (ii) collaboration revenue for development services under the CCX140 agreement.

Research and development expenses were $14.3 million for the second quarter, compared to $9.1 million for the same period in 2016. The increase in research and development expenses from 2016 to 2017 was primarily attributable to higher Phase III development expenses due to the initiation of the avacopan Phase III ADVOCATE trial in patients with AAV in the fourth quarter of 2016 and start-up expenses related to the Phase II clinical trial of avacopan for the treatment of C3G. These increases were partially offset by decreases in (i) Phase I clinical development expense due to the completion of enrollment in the Phase I clinical trial for CCX872 in patients with advanced pancreatic cancer in 2016 and (ii) Phase II development expense due to the completion of the avacopan CLEAR and CLASSIC Phase II clinical trials for the treatment of AAV in 2016.

General and administrative expenses were $4.2 million for the second quarter, compared to $3.9 million for the same period in 2016. The increase from 2016 to 2017 was primarily due to higher intellectual property related expenses and accounting related fees associated with preparing to meet the requirements pursuant to the Sarbanes-Oxley Act of 2002.

Net losses for the second quarter were $9.2 million, compared to $10.0 million for the same period in 2016.

Total shares outstanding at June 30, 2017 were approximately 48.6 million shares.

The Company expects to utilize cash and cash equivalents in the range of $50 million and $55 million in 2017.

Cellectar Biosciences’ CLR 131 Achieves Overall Survival of Greater Than 22 Months in Advanced Multiple Myeloma Patients

On August 8, 2017 Cellectar Biosciences, Inc. (Nasdaq: CLRB), an oncology-focused, clinical stage biotechnology company (the "company"), reported its lead PDC compound, CLR 131 has achieved a median overall survival of 22.5 months to date after a single dose infusion of 12.5mCi/m2 in patients with multiple myeloma (Press release, Cellectar Biosciences, AUG 8, 2017, View Source [SID1234520163]). Patients in the first cohort of the company’s Phase 1 clinical trial had an average of 5.8 prior lines of treatment and therefore were considered to be heavily pretreated.

It is important to note that the trial remains ongoing, and the overall survival could continue to increase over time. While there have been no head-to-head studies, for comparison, this ongoing overall survival length from the company’s Phase 1 clinical trial exceeds historic published outcomes of currently marketed second and third line treatment modalities for multiple myeloma.

Phase 1 Clinical Trial Results
The fourth cohort of the company’s Phase 1 clinical trial of CLR 131 in multiple myeloma is fully enrolled. Patients in this cohort received a single infusion providing a dose of 31.25 mCi/m2, and Cellectar expects to report initial results from this cohort by the close of the third quarter 2017, in line with previous guidance. In addition to the patients from the first cohort achieving a median overall survival (mOS) of 22.5 months to date, patients from the second and third cohorts (who received single doses of 18.75 mCi/m2 and 25 mCi/m2) have experienced mOS of 13.2 months and 6.7 months, respectively. As with Cohort One, these cohorts remain ongoing and the overall survival could continue to increase over time. As a result, the company continues to collect overall survival data on all evaluable trial participants and will provide timely updates, as appropriate.

NCI-Supported Phase 2 Trial
The company’s Phase 2 study of CLR 131 in multiple myeloma and other hematologic malignancies was initiated on March 30, 2017 and remains actively enrolling. The study is being conducted at approximately 10-15 cancer centers in the United States for patients with a variety of orphan-designated relapse or refractory hematologic cancers. The study’s primary endpoint is clinical benefit rate (CBR), with additional endpoints of overall response rate (ORR), progression free survival (PFS), median overall survival (mOS) and other markers of efficacy following a single infusion of CLR 131 providing a dose of 25.0 mCi/m2, with the option for a second 25.0 mCi/m2 dose approximately 75-180 days later.

The hematologic cancers studied in the trial include multiple myeloma (MM), chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), lymphoplasmacytic lymphoma (LPL), marginal zone lymphoma (MZL), mantle cell lymphoma (MCL), and potentially diffuse large B-cell lymphoma (DLBCL).

In addition to the CLR 131 infusion(s), MM patients will receive 40 mg oral dexamethasone weekly for up to 12 weeks. Efficacy responses will be determined by the latest International Multiple Myeloma Working Group criteria. Efficacy for all lymphoma patients will be determined according to Lugano criteria.

More information about the trial, including eligibility requirements, can be found at www.clinicaltrials.gov, reference NCT02952508.

"We continue to make meaningful progress on our CLR 131 program and are encouraged by the observed clinical outcomes to date. We look forward to reporting data from the fourth cohort of our Phase 1 trial as well as the single and multi-dose Phase 2 study when available," said Jim Caruso, president and CEO of Cellectar Biosciences. "We also continue to make progress evaluating the clinical utility of CLR 131 in both liquid and solid tumor orphan designated cancers that have potential for accelerated regulatory pathways."

About CLR 131
CLR 131 is an investigational compound under development for a range of hematologic malignancies. It is currently being evaluated as a single-dose treatment in a Phase 1 clinical trial in patients with relapsed or refractory (R/R) multiple myeloma (MM) as well as in a Phase 2 clinical trial for R/R MM and select R/R lymphomas with either a one- or two-dose treatment. CLR 131 represents a novel approach to treating hematological diseases and based upon preclinical and interim Phase 1 study data may provide patients with therapeutic benefits including, overall survival, an improvement in progression-free survival, and overall quality of life. CLR 131 utilizes the company’s patented PDC tumor targeting delivery platform to deliver a cytotoxic radioisotope, iodine-131, directly to tumor cells. The FDA has granted Cellectar an orphan drug designation for CLR 131 in the treatment of multiple myeloma.

About Phospholipid Drug Conjugates (PDCs)
Cellectar’s product candidates are built upon its patented cancer cell-targeting delivery and retention platform of optimized phospholipid ether-drug conjugates (PDCs). The company deliberately designed its phospholipid ether (PLE) carrier platform to be coupled with a variety of payloads to facilitate both therapeutic and diagnostic applications. The basis for selective tumor targeting of our PDC compounds lies in the differences between the plasma membranes of cancer cells compared to those of normal cells. Cancer cell membranes are highly enriched in lipid rafts, which are glycolipoprotein microdomains of the plasma membrane of cells that contain high concentrations of cholesterol and sphingolipids, and serve to organize cell surface and intracellular signaling molecules. PDCs have been tested in more than 80 different xenograft models of cancer.

"In the first half of 2017, we made significant advancements in our dual technology platforms of immuno-oncology and stem cells," commented Tony (Bizuo) Liu, CBMG’s Chief Executive Officer. "In China we successfully launched two Phase I clinical trials for our anti-CD19 CAR-T product C-CAR011 and we expect to report topline clinical data from both trials by year-end. In the United States the development of AlloJoinTM, our "off-the-shelf" allogeneic adipose stem cell candidate, continues to progress with the recent $2.29 million award from California Institute for Regenerative Medicine (CIRM) to establish a cell line and IND filing in the treatment of Knee Osteoarthritis (KOA)." Mr. Liu further stated, "Upon completion of our new Shanghai GMP facility later this year, we believe we will have one of the largest cell therapy facilities in the world. The Shanghai facility will house our joint technology laboratory with GE Healthcare Life Sciences China to co-develop high-quality industrial control processes in CAR-T and stem cell manufacturing. With these recent advancements in our pipelines and validation of our GMP capabilities, we believe we will have the first mover advantage to deliver effective cell therapies in China. The recent unanimous U.S. FDA Advisory Committee approval of a large pharma’s Biological License Application (BLA) designated as Breakthrough Therapy on a CAR-T candidate for the treatment of relapsed/refractory B-cell acute lymphoblastic leukemia (ALL), and the FDA acceptance of another company’s diffuse large B-cell lymphoma (DLBCL) BLA filing under Priority Review, have set a precedent for a substantially shortened review clock for such breakthrough therapies in the United States. With both ALL and DLBCL in our pipeline, we are hopeful to see an analogous accelerated BLA review treatment in China when we are ready for our submission."

"In the second quarter, we continued to see strong physician enthusiasm for our Phase 2 METRIC study of glembatumumab vedotin in triple negative breast cancer and recently met our target enrollment of 300 patients," said Anthony Marucci, Co-founder, President and Chief Executive Officer of Celldex Therapeutics. "We expect enrollment will be formally closed by the end of September to allow all patients currently in the screening queue the opportunity to complete the screening process and enroll in the study."

"In June, we presented data from glemba’s Phase 2 program in checkpoint refractory metastatic melanoma and the Phase 1 dose-escalation varlilumab/Opdivo combination study in solid tumors, both in oral presentations at ASCO (Free ASCO Whitepaper). We anticipate a productive second half of the year as we complete enrollment across multiple early-stage studies and look forward to topline data from the METRIC study in the first half of 2018."

Recent Highlights

Continued progress in METRIC enrollment: Target enrollment (n=300) in METRIC has been reached. Given the lack of treatment options for patients with triple negative breast cancers, previously screened patients whose tumors overexpress gpNMB will be allowed to enter the study before enrollment is formally completed, which is estimated to occur by the end of September 2017. The Company expects topline data from the study approximately six to eight months after formal closing of enrollment. 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 presented in an oral presentation at American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) in June: Mature data (n=62) from the study were presented at ASCO (Free ASCO Whitepaper). As previously reported in October 2016, the primary endpoint of the cohort (threshold of 6 or more objective responses in 52 evaluable patients) was exceeded. 7 of 62 (11%) patients experienced a confirmed response, and an additional three patients also experienced single timepoint partial responses. Since data were reported in October, one patient converted from a confirmed partial response to a confirmed complete response. Median overall survival (OS) for all patients was 9.0 months (95% CI: 6.1, 13.0). Patients who experienced rash in Cycle 1 experienced a more prolonged OS with a median of 15.8 months (p=0.026, HR=0.44) as compared to those who did not experience rash.

Enrollment recently completed in the glembatumumab vedotin and varlilumab combination arm, and data from this portion of the study are 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 presented in an oral presentation at ASCO (Free ASCO Whitepaper): Updated data (n=36) from the Phase 1 portion of this study were presented at ASCO (Free ASCO Whitepaper). The majority of patients enrolled in this study had PD-L1 negative tumor at baseline and presented with stage IV, heavily-pretreated disease. 80% of patients enrolled presented with refractory or recurrent colorectal (n=21) or ovarian cancer (n=8), a population expected to have minimal response to checkpoint blockade. The primary objective of the Phase 1 portion of the study was to evaluate the safety and tolerability of the combination. The combination was well tolerated at all varlilumab dose levels tested without any evidence of increased autoimmunity or inappropriate immune activation. Notable disease control was observed across multiple dosing regimens (stable disease or better for at least 3 months). Three partial responses (PR) were observed including a patient with PD-L1 negative, MMR proficient colorectal cancer, a patient with low PD-L1 (5% expression) squamous cell head and neck cancer and a patient with PD-L1 negative ovarian cancer. A subgroup analysis was conducted in patients with ovarian cancer based on an observed increase of PD-L1 and tumor-infiltrating lymphocytes in this patient population. In patients with paired baseline and on-treatment biopsies (n=13), only 15% were PD-L1 positive (≥ 1% tumor cells) at baseline compared to 77% during treatment (p=0.015). Patients with increased tumor PD-L1 expression and tumor CD8 T cells correlated with better clinical outcome with treatment (stable disease or better).

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.

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 has finalized plans for an open-label Phase 2 study in patients with recurrent/metastatic head and neck squamous cell cancer who are refractory to Erbitux (cetuximab). The Company anticipates initiating this study in the fourth quarter of 2017.

Enrollment ongoing in Phase 1 study of CDX-014: This 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.
Second Quarter and First Six Months 2017 Financial Highlights and Updated 2017 Guidance

Cash position: Cash, cash equivalents and marketable securities as of June 30, 2017 were $154.0 million compared to $167.0 million as of March 31, 2017. The decrease was primarily driven by second quarter cash used in operating activities of $20.8 million. This decrease was partially offset by the receipt of $8.7 million from sales of common stock under the Cantor agreement. At June 30, 2017, Celldex had 127.4 million shares outstanding.

Revenues: Total revenue was $3.8 million in the second quarter of 2017 and $5.4 million for the six months ended June 30, 2017, compared to $1.4 million and $2.7 million for the comparable periods in 2016. The increase in revenue was primarily due to the manufacturing service agreement with the International AIDS Vaccine Initiative.

R&D Expenses: Research and development (R&D) expenses were $25.0 million in the second quarter of 2017 and $50.8 million for the six months ended June 30, 2017, compared to $25.7 million and $53.2 million for the comparable periods in 2016.

The $0.7 million decrease in second quarter R&D expenses was primarily due to a decrease in varlilumab contract manufacturing expenses of $4.3 million, partially offset by an increase in glembatumumab vedotin contract manufacturing expenses of $1.9 million and increases in personnel and facility costs related to the Kolltan acquisition.

The $2.4 million decrease in year-to-date R&D expenses was primarily due to decreases in varlilumab and Rintega contract manufacturing expenses of $5.1 million and $2.6 million, respectively, partially offset by an increase in glembatumumab vedotin contract manufacturing expenses of $3.4 million and increases in personnel and facility costs related to the Kolltan acquisition.

G&A Expenses: General and administrative (G&A) expenses were $6.5 million in the second quarter of 2017 and $13.8 million for the six months ended June 30, 2017, compared to $7.8 million and $17.1 million for the comparable periods in 2016.

The $1.3 million decrease in second quarter G&A expenses was primarily due to lower commercial planning costs of $0.6 million and lower stock-based compensation of $0.4 million.

The $3.3 million decrease in year-to-date G&A expenses was primarily due to lower commercial planning costs of $2.4 million and lower stock-based compensation of $0.9 million.

Loss on Fair Value Remeasurement of Contingent Consideration: Loss on the fair value remeasurement of contingent consideration related to the Kolltan acquisition was $1.0 million in the second quarter of 2017 and $4.4 million for the six months ended June 30, 2017, primarily due to changes in discount rates and the passage of time.

Net loss: Net loss was $28.6 million, or ($0.23) per share, for the second quarter of 2017 and $62.8 million, or ($0.51) per share, for the six months ended June 30, 2017, compared to a net loss of $32.0 million, or ($0.32) per share, and $66.6 million, or ($0.67) per share, for the comparable periods in 2016.

Financial guidance: Celldex believes that the cash, cash equivalents and marketable securities at June 30, 2017, 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 2018; however, this guidance assumes Celldex elects to pay future Kolltan contingent milestones, if any, in stock rather than cash.
