"The team we have assembled at Surface Oncology continues to excel in its execution, both in the clinic with SRF231 and with our later stage preclinical programs targeting CD39 and IL-27," said Jeff Goater, chief executive officer of Surface Oncology. "The overall accomplishments in the field of immuno-oncology have been transformative for patients, but we are driven by the fact that there is so much more to be done to help those affected by cancer. Our diverse portfolio represents a broad and unique approach to fighting cancers, targeting multiple pathways to overcome the immunosuppressive tumor microenvironment."

Selected Corporate Highlights:

Dose escalation continues for phase 1 studies of both SRF231 (CD47) and NZV930 (CD73), with initial data for SRF231 anticipated H1 2019.
IND-enabling studies for both SRF617 (CD39) and SRF388 (IL-27) are ongoing and filings are anticipated around the end of 2019 and early 2020, respectively.
A recent publication in the scientific journal Nature1 highlighted the role of IL-27 in, and its potential as a master switch of, the expression of certain checkpoint proteins.
Two scientific posters highlighting SRF231 were accepted for presentation at the 60th American Society for Hematology (ASH) (Free ASH Whitepaper) Annual Meeting in San Diego, CA:
° "The fully human anti-CD47 antibody SRF231 has dual-mechanism antitumor activity against chronic lymphocytic leukemia (CLL) cells and increases the activity of both rituximab and venetoclax"
° "Targeted inhibition of CD47-SIRP alpha requires Fc-Fc Gamma receptor interactions to maximize phagocytosis in T-Cell lymphomas" (Oral presentation)
Expansion of our facility at 50 Hampshire St., Cambridge, MA began in September. The expansion is slated for completion in Q4 and will add over 12,000 square feet of both laboratory and office space.
Financial Results:
As of September 30, 2018, cash, cash equivalents and marketable securities were $173.4 million, compared to $185.6 million on June 30, 2018. Research and development (R&D) expenses were $15.8 million for the third quarter ended September 30, 2018, compared to $12.1 million for the same period in 2017. The increase was primarily driven by expenditures associated with Surface’s advancing product pipeline, including increased R&D personnel costs associated with the growth of the Company. R&D expenses included $0.5 million in stock-based compensation expenses for the third quarter of 2018.

General and administrative (G&A) expenses were $4.0 million for the third quarter ended September 30, 2018, compared to $4.7 million for the same period in 2017. The decrease was largely due to a one-time charge related to employee separation costs during the quarter ended September 30, 2017, partially offset by increases in professional fees related to legal and accounting services. G&A expenses included $0.7 million in stock-based compensation expenses for the third quarter of 2018.

For the third quarter ended September 30, 2018, net loss was $17.2 million, or basic and diluted net loss per share attributable to common stockholders of $0.62. Net loss was $14.4 million for the same period in 2017, or basic and diluted net loss per share attributable to common stockholders of $5.75.

Cellectis Reports Financial Results for 3rd Quarter and First Nine Months 2018

Third Quarter 2018 and Recent Highlights

UCART123 (wholly controlled) – AML & BPDCN patients

The Phases 1 dose escalation studies of UCART123 in acute myeloid leukemia (AML) and blastic plasmacytoid dendritic cell neoplasm (BPDCN) patients at MD Anderson Cancer Center and Weill Cornell Medical Center remain ongoing.

For the AML clinical trial, the current dose level of 2.5×105 UCART123 cells per kilogram will be followed by dose levels 2 and 3 with 6.25×105 and 5.05×106 UCART123 cells per kilogram. We are expecting to dose 2-4 patients per dose cohort, with a treatment follow-up period of 4 weeks per patient as well as an option to re-dose responding patients.

UCART22 (wholly controlled) – B-ALL patients

The FDA approved an IND for UCART22, with a first Phase 1 clinical study in B-cell acute lymphoblastic leukemia (B-ALL) adult patients.

UCART22 is the 3rd allogeneic, off-the-shelf, gene-edited CAR T-cell product candidate developed by Cellectis to enter clinical trials.

UCART22 is designed for the treatment of CD22-expressing cancer cells. Like CD19, CD22 is a cell surface antigen expressed from the pre-B-cell stage of development through mature B-cells and is expressed in more than 90% of patients with B-ALL. Approximately 85% of ALL cases involve precursor B-cells (B-ALL). The clinical research for UCART22 will be led by Dr. Nitin Jain, Assistant Professor at The University of Texas MD Anderson Cancer Center in Houston, and Prof. Hagop Kantarjian, Professor and Chair in the Department of Leukemia and University Chair in Cancer Medicine, at The University of Texas MD Anderson Cancer Center in Houston.

UCARTCS1 (wholly controlled) – Multiple Myeloma patients

A clinical trial for UCARTCS1 is expected to start in 2019 in Multiple Myeloma patients.

UCARTCS1 is our first allogeneic CAR T-cell product candidate for the treatment of Multiple Myeloma (MM) patients. We have chosen CS1 (also known as SLAMF7) as the targeted antigen for this program, based on the high levels of expression of CS1 in MM patients on malignant cells relative to the low level of expression on non-malignant cells as well as on the results of third parties’ proof of concept for this high value target achieved with the elotuzumab monoclonal antibody in MM patients.

UCART19 (partnered, exclusively licensed to Servier) – ALL patients

Recently, an abstract titled "896 Preliminary Data on Safety, Cellular Kinetics and Anti-Leukemic Activity of UCART19, an Allogeneic Anti-CD19 CAR T-Cell Product, in a Pool of Adult and Pediatric Patients with High-Risk CD19+ Relapsed/Refractory B-Cell Acute Lymphoblastic Leukemia" for oral presentation at the 60th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting, was published online, showing the continued progress of UCART19 in Phase 1 clinical trials, for both pediatric and adult ALL patients.

After UCART19 infusion, 88% of evaluable patients (14/16) achieved a complete remission (CR) or complete remission with incomplete blood cell recovery (CRi) by day 28 or day 42 post UCART19 infusion and 86% (12/14) of these patients were ‘measurable residual disease’ (MRD) negative (MRD- stands for less than 1 leukemic cell among 104 normal cells) assessed by flow or qPCR.

We are pleased to see continued progress for UCART19 under the management of our partner Servier.

Under the collaboration agreement with Servier from 2014, Cellectis is entitled to receive up to $350 million in clinical and regulatory milestone payments, as well as tiered royalties in the high single digits on worldwide sales.

ALLO-715 (BCMA) and ALLO-819 (Flt3) (partnered, exclusively licensed to Allogene)

In addition, Allogene has released (i) an abstract for oral presentation at ASH (Free ASH Whitepaper) 2018 annual meeting, describing pre-clinical research on ALLO-715, an allogeneic BCMA CAR T therapy possessing an off-switch for the treatment of Multiple Myeloma, and (ii) an abstract for a poster presentation for ALLO-819, an allogeneic Flt3 CAR T therapy possessing an off-switch for the treatment of acute myeloid leukemia (AML).

ALLO-715 and ALLO-819 were progressed under a joint research collaboration with Allogene, and are directed to targets that were licensed exclusively from Cellectis. Allogene holds the exclusive global development and commercial rights for these product candidates.

Cellectis remains eligible to receive clinical and commercial milestone payments of up to $2.8 billion, or $185 million per target for 15 targets, and tiered royalties in the high single digits on worldwide sales of any products that are developed by Allogene, as originally agreed to under the June 17, 2014 Collaboration Agreement with Pfizer.

Manufacturing

We are currently in the process of internalizing large parts of our proprietary manufacturing chain for clinical supplies and we are planning to build a proprietary cGMP, commercial scale manufacturing facility in the United States.

Corporate Governance

On August 2, 2018, Cellectis announced the appointment of Dr. Stefan Scherer, M.D., Ph.D., to the role of Senior Vice President Clinical Development and Deputy Chief Medical Officer.

On September 19, 2018, Cellectis announced that Stephan A. Grupp, MD, Ph.D., a leading pediatric oncologist at Children’s Hospital of Philadelphia and Chief of the Section of Cellular Therapy and Transplant at the Children’s Hospital of Philadelphia (CHOP) joined the Company’s Clinical Advisory Board (CAB).

Financial Results

Cellectis’ consolidated financial statements have been prepared in accordance with International Financial Reporting Standards, or IFRS, as issued by the International Accounting Standards Board ("GAAP").

Third Quarter and Nine-months 2018 Financial Results

Cash: As of December 31, 2017, Cellectis had $297.0 million in total cash, cash equivalents and current financial assets compared to $475.9 million as of September 30, 2018. This increase of $178.9 million primarily reflects $227.4 million net cash proceeds provided by follow-on offerings completed by Cellectis and Calyxt, partially offset by the net cash flows used by operating activities of $47.5 million.

We believe that our cash, cash equivalents and current financial assets of $475.9 million as of September 30, 2018 will be sufficient to fund our operations until 2022.

Revenues and Other Income: Total revenues and other income were $2.2 million for the three months ended September 30, 2018 compared to $7.3 million for the three months ended September 30, 2017. Total revenues and other income were $18.5 million for the nine months ended September 30, 2018 compared to $26.7 million for the nine months ended September 30, 2017. The decrease in both periods was primarily attributable to a decrease in recognition of upfront fees already paid to Cellectis and research and development cost reimbursements in relation to collaborations.

R&D Expenses: Total R&D expenses were $18.7 million for the three months ended September 30, 2018 compared to $20.3 million for the three months ended September 30, 2017. Total R&D expenses were $55.2 million for the nine months ended September 30, 2018 compared to $58.5 million for the nine months ended September 30, 2017. The decrease in both periods was primarily driven by decreased non-cash stock-based compensation expenses partially offset by increased wages and salaries.

SG&A Expenses: Total SG&A expenses were $11.6 million for the three months ended September 30, 2018 compared to $12.2 million for the three months ended September 30, 2017. The decrease was primarily attributable by decreased non-cash stock-based compensation expenses partially offset by increased in purchases and external expenses. Total SG&A expenses were $36.8 million for the nine months ended September 30, 2018 compared to $31.8 million for the nine months ended September 30, 2017. The increase was primarily driven by increased purchases and external expenses and wages and salaries partially offset by a decrease in non-cash stock-based compensation.

Net Loss Attributable to Shareholders of Cellectis: Net loss attributable to Shareholders of Cellectis was $22.8 million (or $0.54 per share) for the three months ended September 30, 2018 compared to $26.2 million (or $0.73 per share) for the three months ended September 30, 2017. Net loss attributable to Shareholders of Cellectis was $55.4 million (or $1.38 per share) for the nine months ended September 30, 2018 compared to 72.3 million (or $2.03 per share) for the nine months ended September 30, 2017. The decrease in both periods was primarily driven by financial gains and decrease in non-cash stock-based compensation expense, partially offset by decreased revenues and other income and increased purchases and external expenses and wages and salaries.

Adjusted Net Loss Attributable to Shareholders of Cellectis: Net loss attributable to Shareholders of Cellectis was $15.1 million ($0.36 per share), for the three months ended September 30, 2018 compared to $14.3 million ($0.40 per share) for the three months ended September 30, 2017. Net loss attributable to Shareholders of Cellectis was $28.0 million ($0.70 per share) for the nine months ended September 30, 2018 compared to $34.3 million ($0.96 per share) for the nine months ended September 30, 2017. Please see "Note Regarding Use of Non-GAAP Financial Measures" for reconciliation of GAAP net income (loss) attributable to shareholders of Cellectis to adjusted net income (loss) attributable to shareholders of Cellectis.

"We continue to make significant strides towards building a leadership position in ADCs. In the third quarter, we progressed our Phase 1 dose escalation trial of XMT-1536 for solid tumors expressing NaPi2b and resumed enrollment on our new protocol for the Phase 1 dose escalation trial of XMT-1522 for HER2-expressing cancers," said Anna Protopapas, President and CEO of Mersana Therapeutics. "In addition to advancing our two clinical programs, we have developed innovative new platforms that are enabling us to greatly expand the reach of our therapeutics and the productivity of our discovery engine."

Recent Highlights and Updates

Clinical Programs

· Continued evaluation of once every four week schedule in the Phase 1 dose escalation study of XMT-1536 for the treatment of NaPi2b-expressing. XMT-1536 is a first-in-class Dolaflexin ADC targeting NaPi2b, which is broadly expressed in epithelial ovarian cancer and non-squamous non-small cell lung cancer. XMT-1536 has previously been studied on a once every three week schedule and this quarter we initiated evaluation of a once every four week dosing regimen. This dosing regimen has thus far been well tolerated and, based on the results of this cohort, the company has advanced the study to the next higher dosing level. A phase 2 recommended dose on XMT-1536 is expected in the first half of 2019. Additional data may be shared before selection of a phase 2 dose as it matures and informs our expansion and phase 2 plans.

· Resumed enrollment of Phase 1 dose escalation study of XMT-1522 for the treatment of HER2-expressing cancers. As reported on September 17, 2018, the U.S. Food and Drug Administration (FDA) lifted the partial clinical hold on the Phase 1 study of XMT-1522 and the trial has resumed enrollment. The company expects to select a phase 2 dose in mid2019.

· Presented preclinical data on XMT-1536, a NaPi2b-targeting ADC, at the International Association for the Study of Lung Cancer 19th World Conference on Lung Cancer (IASLC WCLC 2018). In a poster titled "MERS67 is a Novel anti-NaPi2b Antibody and Demonstrates Differential Expression Patterns in Lung Cancer Histologic Subtypes," Mersana demonstrated that proprietary immunohistochemistry reagent MERS67 has the ability to quantify NaPi2b expression in lung adenocarcinoma (ACA). These

data indicate potential uses of MERS67 in characterizing and selecting patients for the XMT1536 clinical trial.

Discovery & Platform Progress

· Substantially advanced research on new ADC platforms. The Company intends to present data on two new platforms at the EORTC-NCI-AACR (Free EORTC-NCI-AACR Whitepaper) Molecular Targets and Cancer Therapeutics Symposium from November 13-16, 2018, in Dublin, Ireland.

· The first abstract, titled "Discovery of the novel, homogeneous payload platform Dolasynthen for Antibody-Drug Conjugates" characterizes Dolasynthen, a next-generation platform allowing for drug homogeneity and precise control of Drug-to- Antibody ratio.

· The second abstract, titled "Indole-Biaryl Pyrrolobenzodiazepines (I-BiPs): A potent and well-tolerated class of DNA mono-alkylating payload for antibody-drug conjugates (ADCs)" characterizes Alkymer, a DNA damaging platform demonstrating superiority in both efficacy and tolerability to existing DNA damaging platforms.

· Performed additional preclinical studies demonstrating the potential of XMT-1522 in NSCLC. The Company intends to present preclinical data on XMT-1522 at the EORTC-NCI-AACR (Free EORTC-NCI-AACR Whitepaper) Molecular Targets and Cancer Therapeutics Symposium. The abstract, titled "Target Expression/Efficacy Relationship of XMT-1522, a HER2-targeting Antibody Drug Conjugate (ADC), in an Unselected Series of Non-small Cell Lung Cancer (NSCLC) Primary Human Carcinoma Xenografts" demonstrates deep and durable responses with XMT-1522 treatment across a broad range of patient derived NSCLC xenografts.

Upcoming Events

· The Company will give a corporate presentation at the Credit Suisse Healthcare Conference on November 14, 2018, in Scottsdale, AZ.

· The Company is participating in the 9th Annual World ADC meeting from November 12-15, 2018, in San Diego, CA. Tim Lowinger, the company’s Chief Scientific Officer, will be chairing the meeting.

· The Company will present three data abstracts at the EORTC-NCI-AACR (Free EORTC-NCI-AACR Whitepaper) Molecular Targets and Cancer Therapeutics Symposium from November 13-16, 2018, in Dublin, Ireland.

Financial Results

· Cash, cash equivalents and marketable securities as of September 30, 2018, were $86.1 million, compared to $125.2 million as of December 31, 2017. The company expects that its cash, cash equivalents and marketable securities will enable it to fund its operating plan into 2020.

· Collaboration revenue for the third quarter 2018 was approximately $2.2 million, compared to $6.3 million for the same period in 2017, driven primarily by a reduction of clinical costs in the quarter required to support Takeda collaboration activities and a change in timelines required to achieve a phase 2 dose.

·Research and development expenses for the third quarter 2018 were approximately $15.2 million, compared to $11.4 million for the same period in 2017, driven primarily by an increase in clinical and in regulatory expenses due to the progress of our lead programs and manufacturing costs to support future clinical development.

· General and administrative expenses for the third quarter 2018 were approximately $4.4 million, compared to $2.9 million for the same period in 2017, driven primarily by increased employee-related expenses due to increase in personnel costs and increased professional fees.

· Net loss for the third quarter 2018 was $17.1 million, or $0.75 per share, compared to a net loss of $7.7 million, or $0.35 per share, for the same period in 2017. Weighted average common shares outstanding for the quarter ended September 30, 2018 were 23,152,019 and 22,242,129 for the quarter ended September 30, 2017.

About Dolaflexin

The Dolaflexin platform is designed to increase the efficacy, safety, and tolerability of ADCs by overcomin key limitations of existing technologies. Dolaflexin consists of Fleximer, a biodegradable, highly biocompatible, water soluble polymer, to which are attached multiple molecules of Mersana’s proprietary auristatin drug payload using a linker specifically optimized for use with Mersana’s polymer. The high water-solubility of the Fleximer polymer compensates for the low solubility of the payload, surrounding the payload and protecting it from aggregation and maintaining stability in circulation. Multiple molecules of this Dolaflexin polymer-drug conjugate can then be attached to an antibody of choice, which significantly increases the payload capacity of the resulting ADC. This approach differs from most other ADC technologies that conjugate the payload directly to the antibody. Using its Dolaflexin platform, Mersana has been able to generate ADCs with a very high Drug-to-Antibody Ratio (DAR), between 10 to 15, while maintaining desirable pharmacokinetics and drug-like properties. This represents a three to four-fold increase in DAR relative to traditional ADC approaches. The Dolaflexin platform also incorporates the DolaLock technology, an engineered controlled bystander effect. Auristatin F hydroxypropyl amide (AF-HPA), the initial auristatin drug release product, is freely cell permeable and has bystander-killing capabilities. Intra-tumor metabolism then facilitates the conversion of AF-HPA to auristatin F (AF), which is non-cell permeable, highly potent, and "locked" into the tumor. This enhancement improves both the efficacy and tolerability of Mersana’s ADC candidates.

About XMT-1522

XMT-1522 is a Dolaflexin ADC targeting HER2-expressing tumors. XMT-1522 contains a proprietary HER2 antibody which is conjugated with Mersana’s Dolaflexin platform — a Fleximer polymer linked with a proprietary auristatin payload. XMT-1522 provides a drug load of approximately 12 molecules per antibody, specifically designed to improve potency while simultaneously increasing tolerability. XMT-1522 has the potential to extend HER2-targeted therapy beyond the current "HER2-positive" populations into patients with lower levels of HER2 expression. XMT-1522 is in Phase 1 clinical trials in patients with advanced tumors expressing HER2, including breast cancer, non-small-cell-lung cancer (NSCLC) and gastric cancer patients. More information on the ongoing Phase 1 clinical trial can be found at clinicaltrials.gov.

About XMT-1536

XMT-1536 is a Dolaflexin ADC targeting the sodium-dependent phosphate transport protein (NaPi2b) and is comprised of an average of 10-15 DolaLock payload molecules conjugated to XMT-1535, a proprietary humanized anti-NaPi2b antibody. NaPi2b is an antigen highly expressed in the majority of non-squamous NSCLC and epithelial ovarian cancer. XMT-1536 is in Phase 1 clinical trials in patients with tumors expressing NaPi2b, including ovarian cancer, non-small cell lung cancer (NSCLC) and other cancers. More information on the ongoing Phase 1 clinical trial can be found at clinicaltrials.gov.

Cellectar Announces FDA Grants Exemption to Import Alert for CLR 131 Hematology Studies

On November 12, 2018 Cellectar Biosciences, Inc. (Nasdaq: CLRB), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of drugs for the treatment of cancer, reported that the U.S. Food and Drug Administration (FDA) has granted an exemption to the Import Alert placed on the Centre for Probe Development and Commercialization (CPDC), the sole supplier of the CLR 131 (Press release, Cellectar Biosciences, NOV 12, 2018, View Source [SID1234531227]). The exemption for CLR 131 is effective immediately for all hematology studies and, in response, Cellectar is preparing to dose patients in the second fractionated dose cohort of the Phase 1 relapsed refractory (R/R) multiple myeloma study and the Phase 2 study for R/R hematologic malignancies. The company awaits authorization from the FDA for any future shipments in connection with its Phase 1 study of pediatric patients with neuroblastoma, sarcomas, lymphomas (including Hodgkin’s lymphoma) and malignant brain tumors.

"We thank the FDA for their diligence and for providing this exemption for CLR 131 hematology studies. Our ability to advance our clinical trials and achieve stated business objectives remains our top priority," said James Caruso, president and CEO of Cellectar Biosciences. "I also want to recognize our team for their outstanding execution in support of a rapid resolution."

In its efforts to obtain an exemption for CLR 131 from the Import Alert in hematology and pediatrics, Cellectar has collaborated with the various divisions within the FDA that oversee the company’s investigational new drug applications evaluating CLR 131 in multiple indications. Cellectar executed a series of actions requested by the FDA to obtain an exemption to the Import Alert for its hematology programs. Similarly, the company continues to work with the appropriate division of the FDA to secure an exemption for the pediatric program.

As background, on August 10, 2018, Cellectar announced that CPDC was informed of an FDA Import Alert that prohibited CPDC from supplying CLR 131. While the Import Alert disrupted CLR 131 supply, the basis of the Import Alert was not related to CLR 131 specifically, or to CPDC’s production facility associated with CLR 131. The company actively supported CPDC’s efforts to have the Import Alert lifted as quickly as possible. The FDA subsequently initiated direct talks with Cellectar concerning a possible exemption for CLR 131 from the Import Alert. Those discussions and subsequent actions resulted in the exemption Cellectar is announcing today.

About CLR 131

CLR 131 is Cellectar’s investigational radioiodinated PDC therapy that exploits the tumor-targeting properties of the company’s proprietary phospholipid ether (PLE) and PLE analogs to selectively deliver radiation to malignant tumor cells, thus minimizing radiation exposure to normal tissues. CLR 131 is in a Phase 2 clinical study in relapsed/refractory multiple myeloma (R/R MM) and a range of B-cell malignancies, and a Phase 1b clinical study in patients with R/R MM exploring fractionated dosing. The objective of the multicenter, open-label, Phase 1b dose-escalation study is the characterization of safety and tolerability of CLR 131 in patients with R/R MM. Patients in Cohorts 1-4 received single doses of CLR 131 ranging from 12.5 mCi/m2 to 31.25 mCi/m2 as well as a fractionated dose of 15.625 mCi/m2 given twice over seven days in Cohort 5. All study doses and regimens have been deemed safe and well tolerated by an independent Data Monitoring Committee. The company plans to initiate a Phase 1 study with CLR 131 in pediatric solid tumors and lymphoma as well as a second Phase 1 study in combination with external beam radiation for head and neck cancer.
