About ADCT-402

ADCT-402 (loncastuximab tesirine) is an antibody drug conjugate (ADC) composed of a humanized monoclonal antibody that binds to human CD19, conjugated through a linker to a pyrrolobenzodiazepine (PBD) dimer toxin. Once bound to a CD19-expressing cell, ADCT-402 is internalized into the cell where enzymes release the PBD-based warhead. CD19 is a clinically validated target for the treatment of B-cell malignancies. The PBD-based warhead has the ability to form highly cytotoxic DNA interstrand cross-links, blocking cell division and resulting in cell death. ADCT-402 is being evaluated in a pivotal Phase II clinical trial in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) (NCT03589469). The U.S. Food and Drug Administration granted orphan drug designation to ADCT-402 for the treatment of DLBCL and mantle cell lymphoma.

About ADCT-301

ADCT-301 (camidanlumab tesirine) is an antibody drug conjugate (ADC) composed of a monoclonal antibody that binds to CD25 (HuMax-TAC, licensed from Genmab A/S), conjugated to the pyrrolobenzodiazepine (PBD) dimer payload tesirine. Once bound to a CD25-expressing cell, ADCT-301 is internalized into the cell where enzymes release the PBD-based warhead. The intra-tumor release of its PBD warhead may cause bystander killing of neighboring tumor cells. In addition, the PBD warhead will

trigger immunogenic cell death, which in turn will strengthen the immune response against tumor cells. ADCT-301 is being evaluated in ongoing Phase Ia/Ib clinical trials in patients with relapsed or refractory Hodgkin lymphoma and non-Hodgkin lymphoma (NCT02432235), as well as a Phase Ib clinical trial in solid tumors (NCT03621982).

Spotlight Session

Lasofoxifene decreases breast cancer lung and liver metastasis in a mammary intraductal (MIND) xenograft model of mutant ER-alpha+ breast cancer
Presenting author Muriel Lainé, Ph.D., University of Chicago
Poster Session 7 (PD7-09); Fri., Dec. 7, 7am-9am
One poster introduces a Phase 2 trial of oral lasofoxifene, evaluating its activity versus intramuscular fulvestrant for the treatment of postmenopausal women who have locally advanced or metastatic estrogen receptor-positive (ER+)/HER2- breast cancer with an ESR1 (estrogen receptor gene) mutation. Another poster, selected for a spotlight session on endocrine resistance, is Sermonix-sponsored research from the University of Chicago Ben May Department for Cancer Research in a MIND xenograft model of mutant ER+ breast cancer. The third poster will share results of a study on medical oncologists’ knowledge, awareness and perceptions of precision medicine and liquid biopsy biomarker testing specific to breast cancer and ESR1 mutations.

"Lasofoxifene’s potency and newly discovered activity in ESR1 mutations may hold promise for patients who have acquired resistance in an area of significant unmet medical need," said David Portman, M.D., Sermonix founder and chief executive officer. "We look forward to presenting exciting data at this year’s San Antonio Breast Cancer Symposium as we move lasofoxifene forward as a targeted therapy for women with advanced breast cancer."

"Clinical data have shown a significant reduction in the incidence of ER+ breast cancer in postmenopausal women with osteoporosis who were treated with lasofoxifene," said Paul Plourde, M.D., Sermonix vice president of clinical development. "Further non-clinical and clinical study results provide a strong rationale for pursuing a Phase 2 clinical trial comparing lasofoxifene to fulvestrant, a current widely used injectable medication for advanced breast cancer."

"Lasofoxifene’s ability to reduce primary tumor weights and inhibit metastasis of ER-mutated breast cancer xenografts in a mouse mammary intraductal (MIND) model was reported at the Annual Meeting of the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) in June this year," said Geoffrey Greene, Ph.D., chair of the Ben May Department for Cancer Research and co-director of the Ludwig Center for Metastasis Research at the University of Chicago. "We look forward to sharing new data on lasofoxifene’s impact on lung and liver metastases in breast cancer xenografts that express mutant ER."

Muriel Lainé, a senior research professional in Greene’s lab, will serve as presenting author for the Spotlight Session in San Antonio.

About Lasofoxifene

Lasofoxifene is an investigational, nonsteroidal selective estrogen receptor modulator (SERM), which Sermonix licensed from Ligand Pharmaceuticals Inc. (NASDAQ:LGND) and has been studied in previous comprehensive Phase 1-3 non-oncology clinical trials in more than 15,000 women worldwide.

Lasofoxifene’s binding affinity and activity in mutations of the estrogen receptor could potentially hold promise for patients who have acquired endocrine resistance and ESR1 mutations, a common mutation in the metastatic setting and an area of high unmet medical need. Lasofoxifene’s novel activity in ESR1 mutations was recently discovered and Sermonix has exclusive rights to develop and commercialize it in this area. A potent, well-characterized and bioavailable SERM, lasofoxifene, if approved, could play a critical role in the personalized treatment of advanced ER+ breast cancer.

Antibody–drug conjugates (ADCs) are an emerging class of therapeutic agents with the potential to revolutionize current treatment strategies and regimens to fight cancer. The combination of APC’s proprietary site-selective protein modification technology and Heidelberg Pharma’s proprietary ATAC technology, featuring the mushroom toxin amanitin, has led to conjugates that possess high target-specific anti-cancer potency established in several human cancer cell types.

The Company is pleased to announce that the lead ADC has now impressively demonstrated complete tumor regression at a single low dose in two challenging mouse models of human cancer (JIMT-1, NCI-N87) over extended observation periods with clear superiority over benchmark molecules used as positive controls. The potency and efficacy exhibited by the ADC is profound and the studies are still ongoing, as the improved condition of the test animals permitted a longer-term evaluation than originally contemplated.

Dr. Allen Krantz, CSO and Founder of APC commented "These exciting results have exceeded our high expectations. APC’s ability to rapidly generate superior antibody-drug conjugates without having to perform labor-intensive engineering of the antibody to enable the point of selective attachment of the drug, represents a game changing advantage for our Company in the field of ADCs. Our site selective approach of linking drugs to a favored and universally present site in therapeutically-important antibodies is a powerful and efficient way of producing homogeneous cancer killing ADCs with excellent biophysical properties. The validation of our technology now opens the door to advanced state-of-the-art therapeutic approaches, which are in progress, and for which we have recently filed key patents."

APC and Heidelberg Pharma have agreed to extend their collaboration in two important ways. Heidelberg Pharma are in the process of negotiating terms for APC’s linker technology to be included in the amanitin tool box available to pharma partners developing new ADCs. Also, Heidelberg Pharma and APC will continue to identify and test ADC drug candidates that best exploit the combined strengths of both our technologies.

Dr. Andreas Pahl, CSO of Heidelberg Pharma, said "APC’s linker technology, which does not require any modification of the natural framework of an antibody prior to its conversion into a drug, can significantly streamline development of a new generation of ADCs from existing, well proven antibodies."

Bill Dickie, President and CEO of APC added "We are pleased to extend our collaboration with Heidelberg Pharma’s innovative technology and outstanding team, as we work together to advance the field of ADCs and build value for our companies."

"During the last quarter Celsion made excellent progress with our clinical development programs, including completion of enrollment in our 550-patient global, pivotal Phase III OPTIMA Study of ThermoDox in primary liver cancer in August 2018, as expected, and initiation of patient enrollment in our 130-patient follow-on Phase I/II randomized OVATION 2 Study of GEN-1 in patients newly diagnosed with ovarian cancer," said Michael H. Tardugno, Celsion’s chairman, president and chief executive officer. "We continue to maintain a tight operational focus that both conserves cash and enables the timely execution of clinical trials for both of our promising product candidates. In combination with a financing strategy that minimizes dilution and focuses on shareholder value, we have established a cash runway that extends well beyond the time frame necessary to realize the transformational milestones that lie ahead over the next 18 months. In October 2018, we took steps to eliminate the warrant overhang created from our earlier financings in 2016 and 2017 resulting in a clean capitalization structure."

Recent Developments

Enrollment Completed for 550-Patient Global, Pivotal Phase III OPTIMA Study of ThermoDox in Primary Liver Cancer. In September 2018, the Company announced completion of enrollment of 550 patients in the Company’s pivotal, Phase III OPTIMA Study, a multinational, randomized, double-blind, placebo-controlled clinical trial of ThermoDox in combination with radiofrequency ablation (RFA) for the treatment of patients with hepatocellular carcinoma (HCC), also known as primary liver cancer. The primary endpoint for the study is overall survival (OS). The first of two planned interim efficacy analyses by the study’s Data Monitoring Committee (DMC) is expected in mid-2019.

First Patient Randomized in the Gene-Mediated Immunotherapy (GEN-1) Study of Newly Diagnosed Patients With Stage III/IV Ovarian Cancer. In September 2018, the first patient was dosed in the OVATION 2 Study, a randomized, Phase I/II clinical trial of GEN-1, the Company’s DNA-based immunotherapy for the localized treatment of ovarian cancer as an adjuvant to chemotherapy current standard of care. OVATION 2 will be conducted at 10 treatment centers in the U.S. and will include up to 130 patients with Stage III/IV ovarian cancer, with 12 patients in the Phase I portion and up to 118 patients in Phase II.

Final Progression-Free Survival (PFS) Data From GEN-1 Phase IB Gene-Mediated Immunotherapy Study of Patients With Stage III/IV Ovarian Cancer. In October 2018, Celsion announced final clinical results from the dose escalating Phase IB OVATION I trial evaluating neoadjuvant chemotherapy (NAC) and GEN-1 in newly diagnosed patients with Stage III/IV ovarian cancer. Median PFS in patients treated per protocol (n=13) was 24.3 months and was 17.1 months for the intent-to-treat population (n=18) for all dose cohorts, including three patients who dropped out of the study after 13 days or less, and two patients who did not receive full NAC and GEN-1 cycles.

Program Overview of Celsion’s Gene-Mediated Immunotherapy Designed to Improve Administration of IL-12 and PFS in Patients With Ovarian Cancer Published in the Peer-Reviewed Journal, Future Oncology. In October 2018, an overview of GEN-1 was published in the peer-reviewed journal Future Oncology. The article, co-authored by Premal H. Thaker, M.D., M.S., associate professor of obstetrics and gynecology at the Siteman Cancer Center at the Washington University School of Medicine in St. Louis, Mo. and principal investigator in Celsion’s GEN-1 development program, outlines the DNA plasmid, gene-based concept and the key attributes supporting GEN-1’s mechanism of action characterized by local and persistent delivery of IL-12 and modulation of the tumor microenvironment favoring immune stimulation.

Corporate Development

Celsion’s Application to Sell its New Jersey State Net Operating Losses (NOLs) for the Tax Years 2011 to 2017 Approved. In September 2018, the Company announced it has received approval from the New Jersey Economic Development Authority’s (NJEDA) Technology Business Tax Certificate Transfer program to sell the Company’s unused New Jersey State NOLs and R&D tax credits, totaling $12.5 million for the tax years 2011 to 2017. The Company anticipates that successful transfer of these credits will result in receipt of approximately $10 million in net cash proceeds to the Company prior to the end of 2018.

Elimination of Warrant Overhang

In October 2018, the Company and certain investors holding warrants to collectively purchase 1.64 million shares of the Company’s common stock, which were received in the February 2017 Public Offering and the October 2017 Underwritten Offering, entered into warrant exchange agreements whereby the Company issued 820,714 shares of its common stock in exchange for the warrants. The Company exchanged 0.5 share of common stock for each of 1.64 million warrants with exercise prices between $3.00 per share and $3.22 per share. Doing so, the Company believes that it has eliminated the warrant overhang on its share price and the potential to use these warrants as a vehicle to hedge a short position. As of November 14, 2018, the Company has 18.7 million shares outstanding and 1.6 million warrants outstanding, of which 1.2 million of these outstanding warrants have an exercise price over $6.00 per share and will expire in early April 2019.

Financial Results

For the quarter ended September 30, 2018, Celsion reported a net loss attributable to common shareholders of $4.7 million, or a loss of $0.26 per share, compared to a loss of $5.7 million, or a loss of $0.70 per share, in the same period of 2017. Operating expenses were $4.1 million in the third quarter of 2018, which represented an 8% decrease from $4.5 million in the same period of 2017. During the third quarter ended September 30, 2018, the Company incurred $0.6 million in non-cash stock option expense compared to $0.1 million in the third quarter of 2017.

For the nine-month period ended September 30, 2018, the Company reported a net loss attributable to common shareholders of $17.4 million, or a loss of $1.00 per share, compared to a loss of $16.1 million, or a loss of $3.04 per share, in the same nine-month period of 2017. Operating expenses were $16.7 million during the first nine months of 2018 compared to $14.2 million in the same period of 2017. During the first nine months of 2018, the Company incurred $4.0 million in non-cash stock option expense compared to $1.0 million in the comparable nine-month period of 2017.

Net cash used for operating activities was $13.1 million in the first nine months of 2018, compared to $12.4 million in the same nine-month period in 2017. The Company ended the third quarter of 2018 with $22.0 million of total cash, cash equivalents, investment securities and interest receivable, which included $10 million in gross proceeds from the Company’s venture debt facility completed on June 27, 2018 with Horizon Technology Finance Corporation. The Company expects to receive approximately $10 million from the sale of its New Jersey state NOLs in the fourth quarter of 2018, which is expected to contribute to funding operations into the fourth quarter of 2020.

Research and development (R&D) expenses decreased by $1.1 million, from $3.3 million in the third quarter of 2017 to $2.2 million in the third quarter of 2018. Costs associated with the OPTIMA Study decreased by $1.1 million to $0.7 million in the third quarter of 2018 compared to $1.8 million in the same period of 2017. This decrease resulted from cost concessions negotiated with the Company’s lead contract research organization (CRO) for the OPTIMA Study as well as lower monthly CRO fees after completion of enrollment of this Phase III study during the third quarter of 2018. Costs associated with the initiation of the OVATION 2 Study were $0.2 million in the third quarter of 2018. Other R&D costs related to clinical supplies and regulatory support for the ThermoDox development program decreased by $0.2 million in the third quarter of 2018 when compared to the same prior-year period.

R&D expenses decreased by $0.4 million, from $9.9 million in the first nine months of 2017 to $9.5 million in the first nine months of 2018. Clinical development costs for the Phase III OPTIMA Study decreased to $4.0 million in the first half of 2018, compared to $4.9 million in the first nine months of 2017. This decrease of $0.9 million resulted from cost concessions negotiated with the lead CRO for the OPTIMA Study as well as lower monthly CRO fees after completion of enrollment of this Phase III study during the third quarter of 2018. Costs associated with the initiation of the OVATION 2 Study were $0.4 million in the first nine months of 2018. Other R&D costs related to clinical supplies and regulatory support for the ThermoDox and GEN-1 clinical development programs increased by $0.2 million in the first nine months of 2018 when compared to the same prior-year period. In the first nine months of 2018, the Company also incurred an increase of $0.8 million in non-cash stock compensation expense, compared to the same period of 2017. Partially offsetting these increased costs was a plan implemented by the Company in the first half of 2017 designed to reduce costs associated with the support of ThermoDox clinical studies and other initiatives in Europe. The majority of the $0.5 million in cost savings for personnel and support services in Europe were realized in the first half of 2017.

General and administrative (G&A) expenses were $2.0 million in the third quarter of 2018, compared to $1.2 million in the same period of 2017. General and administrative expenses were $7.2 million in the first nine months of 2018, compared to $4.3 million in the same period of 2017. These increases were primarily attributable to (i) an increase in non-cash stock compensation expense totaling $0.4 million in the third quarter of 2018 and $2.0 million in the first nine months of 2018 when compared to the same periods in 2017 and (ii) an increase in professional fees of approximately $0.2 million in the third quarter of 2018 and $0.7 million in the first nine months of 2018 primarily related to recruiting fees for several new positions to support the anticipated regulatory and commercialization efforts for ThermoDox.

During the third quarter ended September 30, 2018, other expenses included a non-cash charge of $4.5 million related to the impairment of certain in-process research and development assets related to the development of our glioblastoma multiforme (GBM) cancer product candidate offset by a $4.1 million reduction in the earn-out liability related to potential milestone payments for the GBM product candidate. During the third quarter ended September 30, 2017, other expenses included a non-cash charge of $2.5 million related to the impairment of certain in process research and development assets related to the development of our GBM) cancer product candidate offset by a $1.2 million reduction in the earn-out liability related to potential milestone payments for the GBM product candidate.

During the nine-month period ended September 30, 2017, the Company recognized deemed dividends totaling $0.4 million related to multiple agreements with certain warrant holders, pursuant to which these warrant holders agreed to exercise, and the Company agreed to reprice, certain warrants. Warrants to purchase 790,410 shares of common stock were repriced at $2.70 and warrants to purchase 506,627 shares of common stock were repriced at $1.65. The Company received $3.0 million in gross proceeds from the sale of these repriced warrants.
