- Completed $15 million registered direct offering in April 2024 extending the Company’s cash runway.

Financial Highlights

- Cash and cash equivalents of $12.6 million as of March 31, 2024;

- $15 million in gross proceeds from a registered direct offering on April 30, 2024, extends the Company’s cash runway through December 2024;

- R&D expenses were $3.6 million and $6.2 million for the three and six months ended March 31, 2024, respectively, compared to $4.7 million and $8.2 million for the three and six months ended March 31, 2023, respectively;

- G&A expenses were $4.3 million and $7.9 million for the three and six months ended March 31, 2024, respectively, compared to $4.8 million and $7.4 million for the three and six months ended March 31, 2023, respectively;

- Stock-based compensation expense was $3.1 million and $6.1 million for the three and six months ended March 31, 2024, respectively, compared to $1.2 million and $2.4 million for the three and six months ended March 31, 2023, respectively; and,

- Net loss was $8.5 million and $17.8 million, or ($0.05) and ($0.11) per share for the three and six months ended March 31, 2024, respectively, compared to a net loss of $10.5 million and $14.1 million, or ($0.07) and ($0.10) per share for the three and six months ended March 31, 2023, respectively.

"I am pleased to share that we made solid progress this quarter as we focused on execution and managing our finances. The data analysis of our late-stage asset, Mino-Lok, the only treatment of its kind in development to salvage infected catheters, remains on track. We look forward to reporting the topline results later this quarter. Once we review the results, we plan to engage with the FDA to determine the optimal next steps in the program and look forward to advancing this much-needed alternative to the current standard of care, which often involves painful and costly catheter removal and replacement," stated Leonard Mazur, Chairman and CEO of Citius.

"Importantly, the BLA submission for LYMPHIR, our novel IL-2 receptor targeted oncology therapy, was accepted by the FDA, and assigned a late summer 2024 PDUFA target action date. In anticipation of potential approval, we continue to align the organization for a successful launch," added Mazur.

"Despite a tough capital market environment for pre-revenue companies, we successfully completed a $15 million registered direct offering, expanding our cash runway and providing capital to support the execution of our strategic plan. We believe that the merger of our oncology subsidiary with TenX to form a publicly listed company will make our company more attractive to investors and increase the value of our assets. This transaction is progressing, and we expect it to be completed in the coming months as we finalize SEC review and await approval by TENK shareholders. As we continue to meet our goals, we believe additional opportunities to strengthen our capital structure will become available," concluded Mazur.

SECOND QUARTER 2024 FINANCIAL RESULTS:

Liquidity

As of March 31, 2024, the Company had $12.6 million in cash and cash equivalents.

As of March 31, 2024, the Company had 159,094,781 common shares outstanding.

Based on our cash and cash equivalents as of March 31, 2024, and after giving effect to a capital raising that closed on April 30, 2024, we expect to have sufficient funds to continue our operations through December 2024. We expect to raise additional capital in the future to support our operations beyond December 2024.

Research and Development (R&D) Expenses

R&D expenses were $3.6 million for the quarter ended March 31, 2024, compared to $4.7 million for the quarter ended March 31, 2023. For the six months ended March 31, 2024, R&D expenses were $6.2 million as compared to $8.2 million during the six months ended March 31, 2023, a decrease of $1.9 million. The decrease primarily reflects incremental costs related to the completion of the Mino-Lok Phase 3 trial and remediation activities for the LYMPHIR BLA resubmission, offset by lower costs in the current period due to the completion of the Halo-Lido Phase 2b trial.

We expect that research and development expenses will stabilize at current levels in fiscal 2024 as we focus on the commercialization of LYMPHIR, complete our Phase 3 trial for Mino-Lok, and analyze the data from our Phase 2b trial and begin planning our Phase 3 trial for Halo-Lido

General and Administrative (G&A) Expenses

G&A expenses were $4.3 million for the quarter ended March 31, 2024, compared to $4.8 million for the quarter ended March 31, 2023. The decrease was primarily due to lower costs for pre-launch and market research activities associated with LYMPHIR during the period.

For the six months ended March 31, 2024, G&A expenses were $7.9 million as compared to $7.4 million during the six months ended March 31, 2023. The primary reason for the increase was higher costs for pre-launch and market research activities associated with LYMPHIR.

General and administrative expenses consist primarily of compensation costs, professional fees for legal, regulatory, accounting, and corporate development services, and investor relations expenses.

Stock-based Compensation Expense

For the quarter ended March 31, 2024, stock-based compensation expense was $3.1 million as compared to $1.2 million for the quarter ended March 31, 2023. For the six months ended March 31, 2024, stock-based compensation expense was $6.1 million as compared to $2.4 million for the six months ended March 31, 2023. The increase is primarily due to the Citius Oncology stock plan.

Net loss

Net loss was $8.5 million, or ($0.05) per share for the quarter ended March 31, 2024, compared to a net loss of $10.5 million, or ($0.07) per share for the quarter ended March 31, 2023. The $2 million decrease in the net loss was due to decreases of $1.1 million in research and development expenses and $0.5 million in general and administrative expenses, and the increase in other income of $2.3 million, being partially offset by the increase in stock-based compensation expense of $1.9 million.

Net loss was $17.8 million, or ($0.11) per share for the six months ended March 31, 2024, compared to a net loss of $14.1 million, or ($0.10) per share for the six months ended March 31, 2023. The increase in the net loss was primarily due to the increase in stock-based compensation expense.

On May 14, 2024 Cellectar Biosciences, Inc. (NASDAQ: CLRB), a late-stage clinical biopharmaceutical company focused on the discovery, development, and commercialization of drugs for the treatment of cancer, reported financial results for the quarter ended March 31, 2024, and provided a corporate update (Press release, Cellectar Biosciences, MAY 14, 2024, View Source [SID1234643212]).

"We plan to announce data from our CLOVER WaM pivotal study evaluating iopofosine I 131 in Waldenstrom’s macroglobulinemia in June and are on track to submit our NDA in the second half of 2024. We remain pleased with patient enrollment in the phase 1b pediatric high-grade glioma study and expect to announce data in the second half of 2024," said James Caruso, president, and CEO of Cellectar. "Either alone or in collaboration, we continue to assess the versatility of our delivery platform with a wide range of cancer targeting compounds including peptides, oligos and our alpha-emitting phospholipid radiotherapeutic conjugate, CLR 121225, which is planned to enter a phase 1 study in either triple negative breast or pancreatic cancer no later than first quarter 2025."

First Quarter and Recent Corporate Highlights

· Announced positive topline data achieving its primary endpoint in its CLOVER WaM pivotal study, evaluating iopofosine I 131, a potentially first-in-class, targeted radiotherapy candidate for the treatment of relapsed/refractory Waldenstrom’s macroglobulinemia (WM) patients with a median of four prior lines of therapy. The CLOVER WaM study met its primary endpoint with a major response rate of 61%. The overall response rate was 75.6%. The Company plans to announce data for all evaluable patients in June 2024.

· Reported a complete remission rate of 64% and overall response rate of 73% in highly refractory patients in an investigator-initiated Phase I study of iopofosine in combination with External Beam Radiotherapy in recurrent head and neck cancer. In addition to the high rate of complete remission, durability of clinical activity achieved a 67% overall survival and 42% progression free survival at one year.

· Reported the complete central nervous system clearance in a relapsed/refractory Waldenstrom’s macroglobulinemia patient, providing further validation for iopofosine I 131 to treat solid and hematologic tumors, including those located across the blood-brain barrier.

· Enrolled the first patient in the company’s Phase 1b clinical study of iopofosine I 131 in pediatric high-grade gliomas (pHGG). The study is supported by a $2 million Fast Track SBIR grant from the National Institute of Health’s National Cancer Institute (NCI), which was awarded based in part on the promising Phase 1a trial data.

· Announced promising preclinical data for its proprietary novel alpha-emitting phospholipid radiotherapeutic conjugate, CLR 121225 (225Ac-CLR 121225) an actinium-labeled phospholipid ether (PLE), in pancreatic cancer models. The development of this compound expands the company’s clinical pipeline of PLE cancer targeting compounds to include targeted alpha therapies (TATs).

· Announced strategic partnerships with leading community-based oncology networks Florida Cancer Specialists and American Oncology Network (AON) to advance the treatment of WM in the community setting.

First Quarter 2024 Financial Highlights

· Cash and Cash Equivalents: As of March 31, 2024, the company had cash and cash equivalents of $40.0 million, compared to $9.6 million as of December 31, 2023. Net cash used in operating activities during the three months ended March 31, 2024, was approximately $13 million. The company believes its cash balance as of March 31, 2024, is adequate to fund its basic budgeted operations into the fourth quarter of 2024.

· Research and Development Expense: R&D expense for the three months ended March 31, 2024, was approximately $7.4 million, compared to approximately $6.7 million for the three months ended March 31, 2023. The overall increase in R&D expense was primarily a result of increased manufacturing and related costs related to the development of supply chain and production sourcing enhancements, partially offset by a decrease in general research and development costs.

· General and Administrative Expense: G&A expense for the three months ended March 31, 2024, was $4.6 million, compared to $2.1 million for the same period in 2023. The increase in G&A costs was primarily driven by costs associated with the development of infrastructure necessary to support commercialization upon anticipated NDA approval, including the related marketing and personnel costs.

· Net Loss: The net loss attributable to common stockholders for the three months ended March 31, 2024, was ($21.6) million, or $(0.74) per share, compared to $(8.6) million, or ($0.76) per share in the three months ended March 31, 2023.

"It was a catalyst-rich first quarter for Candel, marked by significant advances across both our clinical and preclinical programs," said Paul Peter Tak, MD, PhD, FMedSci, President and Chief Executive Officer of Candel. "Notably, as our clinical data mature with long-term follow up, we are beginning to observe highly differentiated results in long-term survival of patients treated with our viral immunotherapies. An example of these clinical results was recently shared in an update of the phase 2 randomized clinical trial of CAN-2409 in patients with borderline resectable pancreatic cancer, where a notable improvement in overall survival, in patients treated with CAN-2409 plus standard of care chemoradiation, was demonstrated compared to chemoradiation alone. The FDA granted CAN-2409 both Fast Track Designation and Orphan Drug Designation for treatment of patients with pancreatic ductal adenocarcinoma to improve median overall survival and treatment of pancreatic cancer, respectively, providing steady momentum to advance this promising investigational treatment for patients with significant unmet medical need."

Dr. Tak continued, "We are also excited to announce that topline overall survival data from our phase 2 clinical trial of CAN-2409 in patients with stage III/IV non-small cell lung cancer and an inadequate response to immune checkpoint inhibitors will be presented at the upcoming ASCO (Free ASCO Whitepaper) meeting in Chicago on Monday, June 3, 2024."

"In addition to our advances in the clinic, we have made great progress with our enLIGHTENTM Discovery Platform. In April 2024, we presented our second drug candidate from this platform, a first-in-class multimodal immunotherapy candidate for induction of tertiary lymphoid structures, in a late-breaking presentation at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting. We believe this preclinical candidate offers groundbreaking potential in the treatment of cancer," continued Dr. Tak. "We expect to release additional preclinical and clinical data in the coming year, consistent with our commitment to innovation and patient care."

Financial Results for First Quarter Ended March 31, 2024

Research and Development Expenses: Research and development expenses were $4.1 million for the first quarter of 2024 compared to $5.5 million for the first quarter of 2023. The decrease was primarily due to lower employee-related expenses following the corporate restructuring in the fourth quarter of 2023 and lower clinical development costs driven by a reduction in regulatory costs for CAN-2409 programs. Research and development expenses included non-cash stock compensation expense of $0.6 million for the first quarter of 2024 compared to $0.3 million for the first quarter of 2023.

General and Administrative Expenses: General and administrative expenses were $3.8 million for the first quarter of 2024 compared to $4.2 million for the first quarter of 2023. The decrease was primarily due to lower employee-related expenses following the corporate restructuring in the fourth quarter of 2023 and lower insurance costs. These decreases were partially offset by increased professional and consulting fees. General and administrative expenses included non-cash stock compensation expense of $0.5 million for the first quarter of 2024 compared to $0.4 million for the first quarter of 2023.

Net Loss: Net loss for the first quarter of 2024 was $8.2 million, compared to a net loss of $8.8 million for the first quarter of 2023, and included other expense, net of $0.3 million and other income, net $0.8 million, respectively. The change from other income, net in the first quarter of 2023 to other expense, net in the first quarter of 2024 was primarily due to the change in the fair value of the Company’s warrant liability and lower interest income.

Cash Position: Cash and cash equivalents, as of March 31, 2024, were $25.7 million, as compared to $35.4 million as of December 31, 2023. Based on current plans and assumptions, the Company expects that its existing cash and cash equivalents will be sufficient to fund its current operating plan into the fourth quarter of 2024.

About BRUKINSA (zanubrutinib)

BRUKINSA is a small molecule inhibitor of Bruton’s tyrosine kinase (BTK) designed to deliver complete and sustained inhibition of the BTK protein by optimizing bioavailability, half-life, and selectivity. With differentiated pharmacokinetics compared with other approved BTK inhibitors, BRUKINSA has been demonstrated to inhibit the proliferation of malignant B cells within a number of disease-relevant tissues.

About Sonrotoclax (BGB-11417)

Sonrotoclax is an investigational small molecule B-cell lymphoma 2 (BCL2) inhibitor. It belongs to a class of BCL2 homology 3 (BH3) mimetics, and preclinical and IND-enabling studies have demonstrated potent activity and high selectivity of sonrotoclax against the antiapoptotic protein BCL2. Sonrotoclax is more potent and selective for BCL2 relative to BCLxL than venetoclax and shows the potential to overcome common BCL2 resistance mutations.

About BGB-16673

BGB-16673 is an orally available Bruton’s tyrosine kinase (BTK) targeting chimeric degradation activation compound (CDAC) designed to induce degradation of wildtype and multiple mutant forms of BTK, including those that commonly confer resistance to BTK inhibitors in patients who experience progressive disease.

U.S. Indications and Important Safety Information for BRUKINSA (zanubrutinib)

IMPORTANT SAFETY INFORMATION

Warnings and Precautions

Hemorrhage

Fatal and serious hemorrhage has occurred in patients with hematological malignancies treated with BRUKINSA. Grade 3 or higher hemorrhage including intracranial and gastrointestinal hemorrhage, hematuria, and hemothorax was reported in 3.8% of patients treated with BRUKINSA in clinical trials, with fatalities occurring in 0.2% of patients. Bleeding of any grade, excluding purpura and petechiae, occurred in 32% of patients.

Bleeding has occurred in patients with and without concomitant antiplatelet or anticoagulation therapy. Coadministration of BRUKINSA with antiplatelet or anticoagulant medications may further increase the risk of hemorrhage.

Monitor for signs and symptoms of bleeding. Discontinue BRUKINSA if intracranial hemorrhage of any grade occurs. Consider the benefit-risk of withholding BRUKINSA for 3-7 days before and after surgery depending upon the type of surgery and the risk of bleeding.

Infections

Fatal and serious infections (including bacterial, viral, or fungal infections) and opportunistic infections have occurred in patients with hematological malignancies treated with BRUKINSA. Grade 3 or higher infections occurred in 26% of patients, most commonly pneumonia (7.9%), with fatal infections occurring in 3.2% of patients. Infections due to hepatitis B virus (HBV) reactivation have occurred.

Consider prophylaxis for herpes simplex virus, pneumocystis jirovecii pneumonia, and other infections according to standard of care in patients who are at increased risk for infections. Monitor and evaluate patients for fever or other signs and symptoms of infection and treat appropriately.

Cytopenias

Grade 3 or 4 cytopenias, including neutropenia (21%), thrombocytopenia (8%) and anemia (8%) based on laboratory measurements, developed in patients treated with BRUKINSA. Grade 4 neutropenia occurred in 10% of patients, and Grade 4 thrombocytopenia occurred in 2.5% of patients.

Monitor complete blood counts regularly during treatment and interrupt treatment, reduce the dose, or discontinue treatment as warranted. Treat using growth factor or transfusions, as needed.

Second Primary Malignancies

Second primary malignancies, including non-skin carcinoma, have occurred in 14% of patients treated with BRUKINSA. The most frequent second primary malignancy was non-melanoma skin cancers (8%), followed by other solid tumors in 7% of the patients (including melanoma in 1% of patients) and hematologic malignancies (0.7%). Advise patients to use sun protection and monitor patients for the development of second primary malignancies.

Cardiac Arrhythmias

Serious cardiac arrhythmias have occurred in patients treated with BRUKINSA. Atrial fibrillation and atrial flutter were reported in 4.4% patients treated with BRUKINSA, including Grade 3 or higher cases in 1.9% of patients. Patients with cardiac risk factors, hypertension, and acute infections may be at increased risk. Grade 3 or higher ventricular arrhythmias were reported in 0.3% of patients.

Monitor for signs and symptoms of cardiac arrhythmias (e.g., palpitations, dizziness, syncope, dyspnea, chest discomfort), manage appropriately, and consider the risks and benefits of continued BRUKINSA treatment.

Embryo-Fetal Toxicity

Based on findings in animals, BRUKINSA can cause fetal harm when administered to a pregnant woman. Administration of zanubrutinib to pregnant rats during the period of organogenesis caused embryo-fetal toxicity, including malformations at exposures that were 5 times higher than those reported in patients at the recommended dose of 160 mg twice daily. Advise women to avoid becoming pregnant while taking BRUKINSA and for 1 week after the last dose. Advise men to avoid fathering a child during treatment and for 1 week after the last dose. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus.

Adverse Reactions

The most common adverse reactions (≥30%), including laboratory abnormalities, in patients who received BRUKINSA (N=1729) are decreased neutrophil count (51%), decreased platelet count (41%), upper respiratory tract infection (38%), hemorrhage (32%), and musculoskeletal pain (31%).

Drug Interactions

CYP3A Inhibitors: When BRUKINSA is co-administered with a strong CYP3A inhibitor, reduce BRUKINSA dose to 80 mg once daily. For coadministration with a moderate CYP3A inhibitor, reduce BRUKINSA dose to 80 mg twice daily.

CYP3A Inducers: Avoid coadministration with strong or moderate CYP3A inducers. Dose adjustment may be recommended with moderate CYP3A inducers.

Specific Populations

Hepatic Impairment: The recommended dose of BRUKINSA for patients with severe hepatic impairment is 80 mg orally twice daily.

"Tuspetinib (TUS) has now moved to triplet frontline (1L) treatment for newly diagnosed (ND) acute myeloid leukemia (AML) patients who need a superior 1L therapy. The introduction of venetoclax (VEN) to establish the venetoclax/hypomethylating agent (VEN+HMA) doublet was a major advancement in the frontline treatment of ND AML, but response rates still remain too low and survival too short in 1L therapy. Even more concerning, patients who fail a VEN-containing regimen respond poorly to subsequent salvage therapies in the relapsed or refractory (R/R) setting and have a dismal prognosis," said William G. Rice, Ph.D., Chairman, President and Chief Executive Officer of Aptose. "Our solution is the addition of TUS to VEN-HMA to increase response rates, prolong survival, safely improve quality of life, treat a broad spectrum of AML genetic subpopulations, and prevent ND AML patients from becoming resistant to VEN. We’re delighted to have an active protocol to initiate this pilot clinical study and look forward to sharing initial TUS+VEN+HMA triplet data before year-end."

Key Corporate Highlights

Tuspetinib Advancement to TUS+VEN+HMA Triplet Therapy Supported by Extensive Dose Exploration as TUS Single Agent and TUS+VEN Doublet – Tuspetinib, a convenient once daily oral agent that potently targets SYK, FLT3, mutated KIT, JAK1/2, and RSK2 kinases, is being developed for the treatment of patients with ND AML. Tuspetinib avoids many typical toxicities observed with other agents, showing no treatment related QTc prolongation or CPK elevations; no differentiation syndrome; and no drug-related myelosuppression during remission with no drug-related discontinuations or deaths. In the APTIVATE trial, Tuspetinib achieved broad activity across AML patients with a diversity of adverse genetics as a single agent (TUS) and in combination with venetoclax (TUS+VEN) in very ill relapsed/refractory (R/R) and heavily pre-treated AML populations. Blast reductions and responses were observed in patients with Prior-VEN, Prior-FLT3 inhibitor (FLT3i), and Prior-HSCT therapies, those with highly adverse genetics, including mutations in TP53 and RAS genes, and those with mutated or unmutated FLT3 genes. Patients naïve to VEN therapy achieved higher response rates.
Tuspetinib Protocol Now Ready for Triplet Therapy Pilot Study; Clinical Sites Being Activated – Tuspetinib is the ideal third agent for a 1L triplet because of its distinctly favorable safety profile. Tuspetinib enhances antileukemic activity when combined with VEN or HMA in pre-clinical models, Tuspetinib has demonstrated a broad scope of activity across genetic subgroups of AML, and Tuspetinib mechanistically cooperates with VEN to thwart drug resistance. The protocol was submitted to the U.S. Food and Drug Administration (FDA) in Q1, more than 45 days ago, and is currently being activated at clinical sites to initiate the TUS+VEN+AZA triplet pilot study. The new study will enroll ND AML patients who are ineligible to receive intensive induction chemotherapy due to age or co-morbidity. By definition, study participants will be VEN-naïve, FLT3i-naïve, and HMA-naïve, a group that has been shown to be highly responsive to triplet regimens. However, current triplet therapies containing kinase inhibitors can be limited by toxicities often requiring dose reductions of all three agents and are not being pursued in the larger FLT3-unmutated AML population. Clinical sites are now preparing to open the TUS+VEN+HMA triplet study, which is expected to commence enrollment early next quarter. Initial data are expected in the fourth quarter of this year.
Tuspetinib Abstract Accepted for Poster Presentation at EHA (Free EHA Whitepaper) – Aptose will deliver a clinical poster presentation at the European Hematology Association (EHA) (Free EHA Whitepaper) 2024 Hybrid Congress in Madrid, Spain (Poster ID # P557) that describes the safety and efficacy of tuspetinib (TUS) monotherapy and the TUS+VEN doublet in the APTIVATE Phase 1/2 trial with R/R AML patients. The data illustrate the safety and breadth of activity of TUS and TUS+VEN and support our launch of the TUS+VEN+HMA triplet frontline therapy in newly diagnosed AML. A separate preclinical abstract, which has been accepted for e-poster publication, demonstrates that TUS retains nanomolar potency against AML cells engineered to express the NRAS-G12D mutation or selected for resistance to venetoclax (Poster ID # P1756).
Tuspetinib Preclinical Studies Elucidate Mechanistic Cooperativity Among TUS and VEN – Aptose continues to investigate the mechanisms underlying the complementary activity between TUS and VEN. In addition to targeting certain VEN resistance mechanisms, TUS retains activity against VEN-resistant AML cell lines. Likewise, resistance to TUS creates a synthetic lethality for VEN with a 2000-fold increase in sensitivity to VEN. Other studies demonstrate TUS retains potent antitumor activity in preclinical models of human AML resistant to the gilteritinib FLT3 inhibitor (FLT3i), a finding that is clinically validated by response rates to TUS in R/R AML study participants with prior FLT3i treatment.
Nasdaq – On February 29, 2024, Aptose received a deficiency letter from the Listings Qualifications Department of The Nasdaq Stock Market LLC ("Nasdaq") regarding the previously announced private placement with Hanmi Pharmaceutical, Inc. ("Hanmi") which closed in January 2024. In response to the deficiency letter, Aptose submitted a plan to Nasdaq to regain compliance. On April 25, 2024, the Company received confirmation from Nasdaq that the Company had regained compliance with Nasdaq Listing Rule 5635(d) and determined that the matter is now closed. Pursuant to the Company’s plan to regain compliance, on April 26, 2024, the Company announced that it had amended the terms of the warrant agreement with Hanmi to prohibit the exercise of the warrants if such exercise would result in Hanmi owning more than 19.99% of the issued and outstanding shares of Aptose, unless shareholder approval is first obtained.
On April 2, 2024, Aptose received a second Notification Letter from Nasdaq stating that the Company was not in compliance with Nasdaq’s listing rules because the stockholders’ equity as of December 31, 2023, was below the minimum requirement of $2.5 million. The shareholder’s equity as of December 31, 2023 was negative $2.9 million. As of March 31, 2024, the shareholder’s equity is $137,000, positive. Aptose intends to submit a compliance plan on or before May 17, 2024, to monitor stockholders’ equity and, if appropriate, consider further available options to evidence compliance with the requirement.
