Aptose Reports Results for the Fourth Quarter and Full Year 2020
- Conference call and webcast at 5pm EDT today -
- Company announces resignation of CFO Gregory Chow -
- Luxeptinib (CG-806) continues dose escalation and evidence of clinical activity -
SAN DIEGO and TORONTO, March 23, 2021 (GLOBE NEWSWIRE) -- Aptose Biosciences Inc. (“Aptose” or the “Company”) (NASDAQ: APTO, TSX: APS), a clinical-stage company developing highly differentiated agents that target the underlying mechanisms of cancer, today announced financial results for the year and three months ended December 31, 2020 and a corporate update.
The net loss for the quarter ended December 31, 2020 was $14.7 million ($0.17 per share) compared with $7.7 million ($0.13 per share) for the quarter ended December 31, 2019. The net loss for the year ended December 31, 2020 was $55.2 million ($0.67 per share), compared with $26.3 million ($0.52 per share) for the year ended December 31, 2019. Total cash and cash equivalents and investments as of December 31, 2020 were $122.4 million. Based on current operations, Aptose expects that cash on hand and available capital provide the Company with sufficient resources to fund all planned Company operations including research and development into the first half of 2023.
“During 2020, Aptose executed on our three clinical trials which are now all well under way: two studies with our cluster selective kinase inhibitor luxeptinib (CG-806) and one with our MYC repressor APTO-253,” said William G. Rice, Ph.D., Chairman, President and Chief Executive Officer. ”Dose escalation continues in each of these trials, and we and our investigators are encouraged by indicators of luxeptinib’s anti-cancer activity and safety profile. With APTO-253, we are observing consistent MYC repression, an indicator of activity that suggests future potential for broad oncology application. We look forward to providing the next complete data update at the 2021 EHA Virtual Congress.”
Separately, Aptose today announced that Gregory Chow, Executive Vice President and Chief Financial Officer, is resigning to pursue an opportunity at a private biopharma company. Dr. Rice will serve as Chief Accounting Officer and Jotin Marango, M.D., Ph.D., Chief Business Officer will assume Chief Financial Officer duties until a permanent replacement is announced. In addition, Aptose and Mr. Chow intend to enter into a consulting agreement that would become effective upon his departure on March 26, 2021. “It has been an honor and a pleasure to work with Greg,” said Dr. Rice. “Greg has been a trusted business partner and an integral part of the development of Aptose, and Greg departs Aptose on the best of terms and we are certain he will be successful in this next adventure.”
Key Corporate Highlights
- “Luxeptinib” adopted as generic name for CG-806 – The United States Adopted Name (USAN) Council recently adopted “luxeptinib” as the generic name for Aptose’s lead drug candidate CG-806, an oral cluster-selective kinase inhibitor. Aptose will use “luxeptinib” for all future references of the drug, including in scientific publications and corporate materials. After April 1, 2021, the USAN information on luxeptinib will be posted on the USAN Web site (www.ama-assn.org/go/usan).
- Luxeptinib Phase 1 a/b Clinical Study in AML – In October 2020, Aptose announced dosing of the first patient with R/R acute myeloid leukemia (AML) in a Phase 1 a/b clinical study with luxeptinib, the only known clinical agent that potently inhibits both FLT3 and BTK, in addition to other driver kinases, giving it broad therapeutic potential across the spectrum of lymphoid and myeloid hematologic malignancies. Encouraging anti-leukemic activity has been observed at the first dose level of 450mg bid, including a patient with a complete response who remains on study after multiple cycles with no apparent safety signals. Aptose completed the 450 mg bid dose cohort, and has escalated to the 600 mg bid dose. Complete updated data will be presented at EHA in June. Currently, 6 U.S. sites are open for screening and enrolling patients for the study, and more information is available at www.clinicaltrials.gov (NCT04477291).
- Luxeptinib Phase 1 a/b Clinical Study in B-cell Malignancies – Aptose is treating patients at the fifth dose level of 750 mg BID in its Phase 1 a/b dose escalation study with luxeptinib in patients with B-cell malignancies, including chronic lymphocytic leukemia (CLL) and non-Hodgkin’s lymphomas (NHL), who have failed or are intolerant to current therapies. To date, Aptose has observed on-target activity, including inhibition of multiple oncogenic driver kinases, lymphocytosis and tumor reductions. As previously reported at the 2020 ASH Annual Meeting, encouraging benefit has been observed in a patient with follicular lymphoma who has been on luxeptinib for more than one year and remains on drug at this time. At the 750 mg dose, steady state plasma levels exceed 2 micromolar and to date we have observed no safety trends that we believe would prevent further dose escalation. Updated data will be presented at EHA in June. Currently, 30 U.S. sites are open for screening and enrolling patients for the study, and more information is available at www.clinicaltrials.gov (NCT03893682).
- APTO-253 Phase 1 a/b Clinical Study in AML and MDS – APTO-253 is the only known clinical-stage molecule that can directly target and inhibit expression of the MYC oncogene, shown to reprogram survival signaling pathways and contribute to drug resistance in many malignancies, including hematologic malignancies. In the ongoing Phase 1 a/b clinical study of APTO-253 in patients with relapsed or refractory AML or high-risk MDS, Aptose has escalated dosing to the fifth dose level of 150 mg/ m2. APTO-253 treatment has demonstrated MYC repression, an indicator of activity that suggests future potential for broad oncology application. The investigational drug continues to be well tolerated with no evidence of drug-related adverse events, including no observed myelosuppression. More information is available at www.clinicaltrials.gov (NCT02267863).
- Aptose Expansion of Senior Leadership Team – Earlier this month, Aptose announced the appointment of George Melko, Pharm.D., as Vice President, Regulatory Affairs; and Robert Killion Jr., Ph.D. as Vice President, CMC. Dr. Melko brings more than 20 years of senior regulatory experience to Aptose, with a strong focus on oncology. Most recently he served as Vice President of Regulatory Affairs for biotechnology companies Tmunity Therapeutics and Tessa Therapeutics, which included developing regulatory strategy operations, policy and procedure design, serving as an FDA liaison and document preparation/submission. Dr. Killion has been named to the newly established position of Vice President of Chemistry, Manufacture and Control (CMC). Dr. Killion’s more than 20 years of CMC experience span roles in Relypsa, Gilead, Genentech, Roche and Syntex. The full press release can be accessed here.
RESULTS OF OPERATIONS
A summary of the results of operations for the years ended December 31, 2020 and 2019 is presented below:
| Year ended December 31, | ||||||||
| (in thousands except per Common Share data) | 2020 | 2019 | ||||||
| Revenues | $ | — | $ | — | ||||
| Research and development expenses | 29,288 | 16,835 | ||||||
| General and administrative expenses | 26,480 | 10,022 | ||||||
| Net finance income | 530 | 580 | ||||||
| Net loss | $ | (55,238 | ) | $ | (26,277 | ) | ||
| Unrealized gain/(loss) on securities available-for-sale | (18 | ) | 18 | |||||
| Total comprehensive loss | $ | (55,256 | ) | $ | (26,259 | ) | ||
| Basic and diluted loss per Common Share | $ | (0.67 | ) | $ | (0.52 | ) | ||
Net loss of $55.2 million for the year ended December 31, 2020 increased by approximately $28.9 million as compared with $26.3 million for the year ended December 31, 2019, primarily as a result of an increase of $19.1 million in stock-based compensation in the current period, a combined increase in program costs and related labor costs of approximately $9.8 million on our luxeptinib development program and higher cash-based general and administrative expenses of approximately $549 thousand. These expenses were partially offset by lower costs of $545 thousand on our APTO-253 development programs.
Research and Development Expenses
The research and development (“R&D”) expenses for the years ended December 31, 2020 and 2019 were as follows:
| Year ended December 31, | |||||||
| (in thousands) | 2020 | 2019 | |||||
| Program costs – luxeptinib | 16,329 | 8,475 | |||||
| Program costs – APTO-253 | 3,632 | 4,177 | |||||
| Personnel expenses | 5,590 | 3,679 | |||||
| Stock-based compensation | 3,720 | 474 | |||||
| Depreciation of equipment | 17 | 30 | |||||
| $ | 29,288 | $ | 16,835 | ||||
R&D expenses increased by $12.5 million to $29.3 million for the year ended December 31, 2020 as compared with $16.8 million for the comparative period in 2019. Changes to the components of our R&D expenses presented in the table above are primarily as a result of the following activities:
- Program costs for luxeptinib increased by approximately $7.9 million, mostly as a result of higher manufacturing costs, including costs to scale up manufacturing and research costs associated with optimizing the formulation, higher costs associated with the luxeptinib Phase 1a/b trial and the costs associated with the luxeptinib AML trial.
- Program costs for APTO-253 decreased by approximately $545 thousand, mostly as a result of lower manufacturing costs and lower clinical trial costs related to the APTO-253 Phase 1a/b trial.
- Personnel-related expenses increased by $1.9 million, mostly related to new positions hired since the second quarter of 2019 to support the luxeptinib Phase 1a/b and APTO-253 Phase 1a/b clinical trials and the luxeptinib AML Phase 1a/b clinical trial.
- Stock-based compensation increased by approximately $3.2 million in the year ended December 31, 2020, compared with the year ended December 31, 2019, mostly related to an increase in the number of options granted during the year ended December 31, 2020 and a higher grant date fair value of options as compared with the year ended December 31, 2019, and a higher rate of forfeitures in the comparative period in 2019.
General and Administrative Expenses
The general and administrative expenses for the years ended December 31, 2020 and 2019 are as follows:
| Year ended December 31, | ||||||
| (in thousands) | 2020 | 2019 | ||||
| General and administrative, excluding items below: | $ | 8,627 | $ | 8,078 | ||
| Stock-based compensation | 17,718 | 1,822 | ||||
| Depreciation of equipment | 135 | 122 | ||||
| $ | 26,480 | $ | 10,022 | |||
General and administrative expenses for the year ended December 31, 2020 were approximately $26.5 million as compared with $10.0 million for the comparative period in 2019, an increase of approximately $16.5 million. The increase was primarily as a result of the following:
- General and administrative expenses, other than stock-based compensation and depreciation of equipment, increased by approximately $549 thousand in the year ended December 31, 2020 primarily as a result of higher personnel related costs, higher insurance costs and higher office administrative costs offset by lower financing costs and lower travel expenses.
- Stock-based compensation increased by approximately $15.9 million in the year ended December 31, 2020, compared with the year ended December 31, 2019 mostly related to an increase in the number of restricted share units and options granted during the year ended December 31, 2020, and a higher grant date fair value of options as compared with December 30, 2019.
COVID-19 did not have a significant impact on our results of operations for the year ended December 31, 2020. We have not experienced and do not foresee material delays to the enrollment of patients or timelines for the luxeptinib Phase 1a/b trial due to the variety of clinical sites that we have actively recruited for this trial. Similarly, we do not expect our enrollment of the luxeptinib AML trial to be negatively impacted by COVID-19 as we plan to use a variety of clinical sites for this trial as well. APTO-253, which is administered intravenously, requires the need for hospital / clinical site resources to assist and monitor patients during each infusion and, based on the current conditions caused by COVID-19, future enrollment of patients on this trial is likely to be negatively impacted. As of the date of this report, we have not experienced material delays in the manufacturing of luxeptinib or APTO-253 related to COVID-19. Should our manufacturers be required to shut down their facilities due to COVID-19 for an extended period of time, our trials may be negatively impacted.
