"We continue to advance our robust pipeline of T cell engagers and explore their therapeutic potential in areas of unmet medical need," said Julie Eastland, President and Chief Executive Officer of Harpoon Therapeutics. "We anticipate upcoming milestones in the second half of the year for our lead programs from our TriTAC platform and our next generation ProTriTAC T cell engager HPN601 in solid tumors. We look forward to sharing our progress as we work to bring these important therapeutic options to patients."

First Quarter 2022 Recent Highlights and Upcoming Milestones

Enrollment continues across Harpoon’s portfolio of novel T cell engagers for the treatment of cancer:

Tri-specific T cell Activating Construct (TriTAC) Platform

HPN328 (DLL3) Phase 1/2 trial in small cell lung cancer (SCLC) and neuroendocrine cancers

Harpoon plans to present interim clinical results from the ongoing Phase 1 part of the study in a poster presentation at the upcoming American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting 2022 on June 6 at 8:00 a.m. CT.
In May 2022, Harpoon entered into a Master Clinical Supply Agreement with F. Hoffmann-La Roche Ltd for the supply of atezolizumab (Tecentriq) for use in the Company’s planned clinical trials to evaluate HPN328 in combination with atezolizumab for the treatment of patients with SCLC.
In March 2022, the U.S. Food and Drug Administration (FDA) granted Orphan Drug designation to HPN328 for the treatment of patients with SCLC.
Harpoon is continuing dose escalation with the goal to identify expansion dose(s) by year-end 2022.
HPN217 (BCMA) Phase 1/2 trial for relapsed, refractory multiple myeloma

In March 2022, the FDA granted Fast Track designation to HPN217 for the treatment of patients with relapsed, refractory multiple myeloma.
Compelling initial clinical activity observed in dose escalation phase of ongoing trial. Maximum tolerated dose (MTD) has not been reached and enrollment in escalation cohorts continues in first half of 2022.
Harpoon plans to initiate a Phase 2 dose expansion trial in the second half of 2022.
HPN536 (MSLN) Phase 1/2a trial for tumors expressing mesothelin

The dose escalation phase of the ongoing Phase 1/2a clinical trial for cancers expressing mesothelin is ongoing and is expected to be complete by year-end 2022.
ProTriTAC

ProTriTAC is a conditionally active T cell engager platform that is designed to be preferentially active in the tumor. This enables our T cell engagers to address more broadly expressed solid tumor targets across multiple tumor types.

HPN601 (EpCAM)

HPN601 is the first conditionally active T cell engager based on the ProTriTAC platform. EpCAM is expressed in a broad range of solid tumors, including gastrointestinal cancers, potentially enabling HPN601 to address multiple indications with high unmet medical need.
Harpoon expects to advance HPN601 with an IND submission in the second half of 2022.

TriTAC-XR

The proprietary TriTAC-XR extended-release T cell engager platform is designed to minimize on-target cytokine release syndrome (CRS), a characteristic of many T cell engagers that can lead to dose limiting toxicities and can reduce the efficacy of these potent anti-tumor drugs.

In April 2022, preclinical data supporting Harpoon’s TriTAC-XR platform were highlighted in a poster presentation at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting, demonstrating improved safety by minimizing CRS.
First Quarter 2022 Financial Results

Harpoon ended the first quarter of 2022 with $112.5 million in cash, cash equivalents and marketable securities compared to $136.6 million as of December 31, 2021. Current cash is expected to fund operations through the first half of 2023.

Revenue for the quarter ended March 31, 2022 was $5.9 million, compared to $9.0 million for the quarter ended March 31, 2021. The decrease in revenue was primarily due to lower revenue recognized from the Amended and Restated Discovery Collaboration Agreement with AbbVie.

Research and development (R&D) expense for the quarter ended March 31, 2022 was $20.8 million, compared to $16.2 million for the quarter ended March 31, 2021. The increase primarily arose from higher clinical development and personnel-related expense, which included conducting preclinical studies and clinical trials for HPN328, HPN217 and HPN536.

General and administrative (G&A) expense for the quarter ended March 31, 2022 was $5.4 million, compared to $4.6 million for the quarter ended March 31, 2021. The increase was primarily attributable to an increase in personnel expenses related to an increase in headcount and other professional services to support Harpoon’s operations as a public company.

Net loss for the quarter ended March 31, 2022 was $20.3 million, compared to $61.7 million for the quarter ended March 31, 2021. The prior year period included a $50 million legal settlement expense.

On May 12, 2022 Pulmatrix (NASDAQ: PULM), a clinical-stage biopharmaceutical company developing innovative inhaled therapies to address serious pulmonary and non-pulmonary disease using its patented iSPERSE technology, reported first quarter financial results for 2022 and provided a corporate update (Press release, Pulmatrix, MAY 12, 2022, View Source [SID1234614311]).

Ted Raad, Chief Executive Officer of Pulmatrix commented, "We have prioritized capital towards extending our cash runway through the Pulmazole Phase 2b top-line data anticipated in Q2 2024. We anticipate dosing for the Phase 2b study to begin in Q1 2023. Also in 2022, we will further analyze the PUR1800 Phase 1b data to finalize a potential Phase 2 study design while we execute to deliver PUR3100 Phase 1 top-line data in Q4 2022."

First Quarter 2022 and Recent Program Highlights

Pulmazole (PUR1900)

The Pulmazole Phase 2b efficacy study will include a 16-week dosing regimen with potential registration efficacy endpoints, is on track to begin dosing patients in Q1 2023. With a focus on capital conservation, we have extended our projected cash runway through the anticipated top-line data readout in Q2 2024.
PUR3100

On January 25, 2022, the Company conducted a Type C meeting with the FDA to add additional clarification around some of the written pre-IND responses in relation to the overall non-clinical and clinical program. Management concluded that conducting the Phase 1 study in Australia should allow the Company to generate the most comprehensive dataset for inclusion in an IND for Phase 2 in the United States, while also providing the most time efficient path to Phase 1 data in 2022.
PUR1800

On March 21, 2022, the Company announced top-line data from a Phase 1b clinical study of PUR1800 assessing the safety, tolerability and pharmacokinetics of PUR1800 in patients with stable COPD after dosing the first patient in February 2021. We are analyzing the Phase 1b clinical study data for future publication and to finalize design of a potential Phase 2 efficacy study in treatment of AECOPD.
First Quarter Corporate Highlights

On February 28, the Company completed a reverse stock-split at a ratio of 1-for-20 which reduced the number of outstanding shares of the Company’s common stock from approximately 65.9 million shares to 3.3 million shares.

On March 1, the Company announced the hiring of Dr. Margaret Wasilewski as the Company’s Chief Medical Officer. Dr. Wasilewski leverages over 25 years of experience in pharmaceutical drug development.

On March 17, the Company announced that it regained compliance for its listing on Nasdaq, allowing continued access to capital markets and liquidity for its investors.
First Quarter 2022 Financial Results

Revenue was $1.2 million for the first quarter ended March 31, 2022, compared to $1.4 million for the same period in 2021, a decrease of $0.2 million. Revenue for 2022 from the collaboration and license agreement with Cipla on the Company’s Pulmazole program increased, offset by no revenues from a previous JJEI License Agreement for the Company’s PUR1800 kinase inhibitor.

For the three months ended March 31, 2022, research and development expenses were $4.1 million compared to $3.9 million for the same period in 2021, an increase of $0.3 million. The increase was primarily due to increased spend of $0.7 million in employment costs and $0.1 million in rent costs, partially offset by decreased spend of $0.3 million on preclinical costs related to our PUR1800 program and $0.2 million on clinical and manufacturing costs related to the Pulmazole program.

General and administrative expenses were $2.0 million for the three months ended March 31, 2022, compared to $1.6 million for the three months ended March 31, 2021, an increase of $0.4 million. The increase was primarily due to increased spend of $0.1 million in employment costs, $0.3 million on consulting and legal, and $0.1 million on audit, tax and public company expense, partially offset by decreased patent expense of $0.1 million.

Our total cash and cash equivalents balance as of March 31, 2022 was $47.5 million. We expect that our existing cash and cash equivalents as of March 31, 2022 will enable us to fund our projected operating expenses and capital expenditures into Q2 2024.

In contrast to traditional molecular biomarker testing, image-based biomarkers can enable faster turnaround time for results, provide new information at the point of diagnosis and reduces the need for unnecessary and expensive testing on definite negatives, while protecting the integrity of the tissue sample. Specifically, the Paige Prostate Biomarker Suite can detect biomarkers from H&E-stained samples and can inform the need for confirmatory tests such as immunohistochemistry (IHC) or fluorescence in situ hybridization (FISH).

The Paige Prostate Biomarker Suite is designed to assist in the detection of Androgen Receptor (AR), TP53, RB1 and PTEN biomarkers that are associated with the development and progression of prostate cancer. The biomarkers can help physicians stratify patients into treatment paradigms and direct targeted enrollment into clinical trials. The Paige Prostate Biomarker Suite was developed using the same underlying technology from Paige Prostate Detect, which was developed with histology image data from tens of thousands of patients and is already CE-IVD and UKCA marked, in addition to being approved by the FDA in the U.S.

"By employing Paige Prostate Biomarker Suite, clinicians can rapidly reduce laboratory turnaround time while providing a broader range of data at the point of diagnosis," said Jill Stefanelli, Ph.D., President and Chief Business Officer at Paige. "We’re excited by this regulatory milestone of our biomarker capabilities built on our robust AI technology platform, which can rapidly screen and develop proof-of-concept biomarkers. As we expand our biomarker portfolio, we also look forward to developing novel biomarkers across indications to identify patients that should receive genomic testing or could potentially respond to targeted therapies. This opens the door to a whole new range of biomarker applications and, in turn, new opportunities for industry collaboration."

Sujal Shah, President and CEO of CymaBay, stated, "Despite facing ongoing external challenges, we have made steady progress over the past few months enrolling patients in RESPONSE, our second, global phase 3 registration study of seladelpar for patients with primary biliary cholangitis (PBC). We now have over 150 clinical sites activated across 26 countries where we have continued to increase our direct site engagement initiatives. As we approach what we project to be the final months of screening, we have greater visibility into monthly metrics and forecast completion of enrollment in the third quarter. We were also excited to have the results of our 52-week, open-label, Phase 2 study of seladelpar in patients with PBC published in the Journal of Hepatology last month. The opportunity to have these data featured in one of the world’s preeminent medical journals for liver diseases elevates seladelpar’s visibility as a differentiated drug candidate for patients with PBC. Finally, we have continued to navigate the difficult market environment with a focus on diligent expense management leaving us with a strong balance sheet after completing two successful financings in 2021. In the first quarter, we received the third $25 million funding tranche from our non-dilutive, clinical funding agreement with Abingworth and ended the quarter with $193 million of cash, cash equivalents and investments."

Recent Corporate Highlights

Moving towards completion of enrollment in RESPONSE, a 52-week, placebo-controlled, randomized, global, Phase 3 registrational study evaluating the safety and efficacy of seladelpar in patients with PBC. This study is targeting enrollment of 180 patients who have an inadequate response to, or intolerance to, ursodeoxycholic acid, in a 2:1 randomization to oral, once daily seladelpar 10 mg or placebo. The primary outcome measure is the responder rate at 52 weeks. A responder is defined as a patient who achieves an alkaline phosphatase level < 1.67 times the upper limit of normal with at least a 15% decrease from baseline and has a normal level of total bilirubin. Additional key outcomes of efficacy will compare the rate of normalization of alkaline phosphatase at 52 weeks and the level of pruritus at 6-months for patients with moderate to severe pruritus at baseline assessed by a numerical rating scale recorded with an electronic diary. To date we have over 150 sites activated across 26 countries.
Continued strong enrollment in ASSURE, an open-label, long-term study of seladelpar in patients with PBC intended to collect additional long-term safety data to support registration. In April, we successfully rolled over patients completing RESPONSE into ASSURE. Together with patients that entered into ASSURE from prior studies with seladelpar, there are now approximately 140 patients in this study taking daily seladelpar.
Supported enrollment efforts in a Phase 2a proof-of-pharmacology study to evaluate the potential for MBX-2982, a GPR119 agonist, to prevent hypoglycemia in patients with type 1 diabetes. The study is being conducted by the AdventHealth Translational Research Institute in Orlando, Florida and fully funded by The Leona M. and Harry B. Helmsley Charitable Trust with CymaBay retaining full rights to MBX-2982.

Published results from Phase 2, 52-week study of seladelpar in patients with primary biliary cholangitis (PBC) in the Journal of Hepatology. This 52-week, phase 2, dose-ranging, open-label study examined the efficacy and safety of seladelpar in PBC patients who were receiving or intolerant to first-line therapy with ursodeoxycholic acid., The results included:

An interim primary efficacy analysis of ALP change from baseline at Week 8 found that seladelpar treatment provided 26%, 33%, and 41% reductions for the 2 mg, 5 mg and 10 mg doses, respectively (all p<0.005).
Responses were maintained or improved at Week 52, which included dose escalation in 91% and 80% of the 2 mg and 5 mg cohorts, respectively.
At Week 52, the composite biochemical response (ALP <1.67×ULN, ≥15% ALP decrease from baseline, and normal total bilirubin) rates were 64%, 53%, and 67%, and ALP normalization rates were 9%, 13%, and 33% in the 2 mg, 5 mg, and 10 mg cohorts, respectively.
The pruritus visual analog scale score decreased in the 5 mg and 10 mg cohorts.
There were no treatment-related serious adverse events (AEs), and 4 patients discontinued due to AEs.
Expanded the Board of Directors to include Dr. Éric Lefebvre, the Chief Medical Officer of Pliant Therapeutics. Prior to joining Pliant, Dr. Lefebvre served as the Vice President of Research and Development of Allergan plc and before that was Chief Medical Officer of Tobira Therapeutics, Inc. Dr. Lefebvre also led global clinical development and global medical affairs at Janssen Pharmaceuticals for 10 years prior to starting his pharmaceutical career at GlaxoSmithKline Canada.
Received $25 million of funding in January 2022 from Abingworth through a non-dilutive financing agreement for the development of seladelpar, which was executed in July 2021. $75 million has been received to date through the financing agreement. CymaBay also has an option to receive an additional $25 million after the completion of enrollment of the RESPONSE clinical trial.
Held $193.4 million in cash, cash equivalents and investments as of March 31, 2022. We believe that cash and investments on hand, together with committed capital available through the development financing agreement with Abingworth, is sufficient to fund CymaBay’s operating plan through 2023.
First Quarter Ended March 31, 2022 Financial Results

Research and development expenses for the three months ended March 31, 2022 and 2021 were $18.4 million and $12.4 million, respectively. Research and development expenses in the three months ended March 31, 2022 were higher than the corresponding period in 2021 primarily due to an increase in clinical trial activities associated with the ongoing late-stage development of seladelpar in PBC. In particular, cost increases were primarily driven by an expansion of our site activation, patient enrollment, and other clinical trial activities associated with RESPONSE and ASSURE, our two active global late-stage clinical trials in PBC.

General and administrative expenses for the three months ended March 31, 2022 and 2021 were $6.1 million and $5.2 million, respectively. General and administrative expenses in the three months ended March 31, 2022 were higher than the corresponding period in 2021 due to higher employee compensation associated with the hiring of additional personnel and an increase in consulting and other expenses to support our late-stage development of seladelpar in PBC.

Net loss for the three months ended March 31, 2022 and 2021 was $27.8 million and $17.6 million, or ($0.32) and ($0.25) per diluted share, respectively. Net loss was higher largely due to increases in clinical operating expenses, as clinical activity related to our late-stage development of seladelpar in PBC continued to expand and accretion of interest expense related to the Abingworth development financing arrangement. We expect our operating expenses to increase in the future as we continue to execute on our clinical development plans.

"We continue to make excellent progress across our clinical programs and look forward to reporting initial data from our pivotal Phase 2 FIREFLY-1 trial in relapsed pLGG next month," said Jeremy Bender, Ph.D., chief executive officer of Day One. "These initial data will provide preliminary insights into the potential of tovorafenib to transform patient care for the most common childhood brain cancer, which currently has no approved therapies. Beyond FIREFLY-1, we are preparing to initiate a pivotal Phase 3 study, FIREFLY-2, for the first-line treatment of pLGG patients and recently initiated the combination portion of our Phase 2 FIRELIGHT-1 study with tovorafenib and our investigational oral MEK inhibitor, pimasertib. As our clinical programs advance, we continue to accelerate planning for our first potential regulatory submission for tovorafenib in 2023 and execute on our business strategy to make an impact for patients of all ages with life threatening diseases."

Program Highlights

Initial data from FIREFLY-1, a pivotal Phase 2 clinical trial of tovorafenib in relapsed pLGG, is expected in June 2022.

Day One anticipates releasing topline results from the fully-enrolled pivotal study in the first quarter of 2023. Pending positive results from FIREFLY-1, Day One anticipates filing a new drug application (NDA) with the U.S. Food and Drug Administration (FDA) in 2023.

Day One has expanded the FIREFLY-1 study to include two additional study arms:

An expanded access arm that enables treatment for eligible patients once the primary cohort has completed enrollment; and
An advanced solid tumor arm to evaluate the preliminary efficacy of tovorafenib in patients aged 6 months to 25 years with a relapsed or progressive extracranial solid tumors with activating RAF fusion.

Day One plans to initiate a pivotal Phase 3 clinical trial (FIREFLY-2) evaluating tovorafenib as a front-line therapy in pLGG in the second quarter of 2022.

Day One is enrolling patients in the Phase 2 FIRELIGHT-1 trial evaluating tovorafenib monotherapy in adults with recurrent, progressive, or refractory solid tumors harboring MAPK pathway aberrations. Day One recently expanded FIRELIGHT-1 to include a Phase 1b/2 portion to evaluate tovorafenib in combination with pimasertib, Day One’s investigational MEK inhibitor.
First Quarter 2022 Financial Highlights

Cash Position: Cash and cash equivalents totaled $262.7 million on March 31, 2022. Based on Day One’s current operating plan, management believes it has sufficient capital resources to fund anticipated operations into 2024.

R&D Expenses: Research and development expenses were $15.0 million for the first quarter of 2022 compared to $12.6 million for the first quarter of 2021. The increase was primarily due to additional employee compensation costs, clinical trial and product development expenses which were offset by a decrease in milestone payments for licensing agreements.

G&A Expenses: General and administrative expenses were $12.7 million for the first quarter of 2022 compared to $3.5 million for the first quarter of 2021. The increase was primarily due to additional employee compensation costs, initial commercial buildout, and professional expenses to support company growth.

Net Loss: Net loss totaled $27.7 million for the first quarter of 2022 compared to $16.1 million for the first quarter of 2021 with non-cash stock compensation expense of $6.2 million and $0.5 million for the first quarters of 2022 and 2021, respectively.
Upcoming Events

About Tovorafenib
Tovorafenib is an investigational, oral, brain-penetrant, highly-selective type II pan-RAF kinase inhibitor designed to target a key enzyme in the MAPK signaling pathway, which is being investigated in primary brain tumors or brain metastases of solid tumors. Tovorafenib has been studied in over 250 patients to date. Currently tovorafenib is under evaluation in a pivotal Phase 2 clinical trial (FIREFLY-1) among pediatric, adolescent and young adult patients with pediatric low-grade glioma (pLGG), which is an area of considerable unmet need with no approved therapies. Tovorafenib is also being evaluated alone or as a combination therapy for adolescent and adult patient populations with recurrent or progressive solid tumors with MAPK pathway aberrations (FIRELIGHT-1). Tovorafenib has been granted Breakthrough Therapy and Rare Pediatric Disease designations by the U.S. Food and Drug Administration (FDA) for the treatment of patients with pLGG harboring an activating RAF alteration. Tovorafenib has also received Orphan Drug designation from the FDA for the treatment of malignant glioma, and from the European Commission (EC) for the treatment of glioma.

About Pimasertib
Pimasertib is an investigational, oral, highly selective, small molecule inhibitor of mitogen‐activated protein kinases 1 and 2 (MEK-1/-2) within the MAPK signaling pathway. Pimasertib has been dosed in over 850 patients to date for various tumor types. Preclinical data indicates that the combination of a MEK inhibitor, such as pimasertib, and a type II RAF inhibitor, such as tovorafenib, has synergistic anti-tumor activity.

Day One is conducting a Phase 1b/2 study (FIRELIGHT-1) to evaluate the safety, tolerability, and preliminary efficacy of combining pimasertib with tovorafenib in adolescent and adult patients (≥12 years of age) with recurrent, progressive, or refractory solid tumors with MAPK pathway aberrations.
