X4 Pharmaceuticals Provides Corporate Update, Including Expected Impact of COVID-19, and Reports First Quarter 2020 Financial Results


Data from Phase 2 open-label extension trial of mavorixafor in WHIM syndrome
to be presented at the Virtual Edition of the 25th European Hematology Association (EHA)
Annual Congress in June 2020

Company continues to expect data from its Phase 1b Waldenström’s macroglobulinemia
trial in 2H 2020

Company expects a delay into 2022 to report top-line data from its pivotal Phase 3 clinical trial in WHIM syndrome, and a delay into 2021 to report initial data from its Phase 1b trial in Severe Congenital Neutropenia (SCN) due to COVID-19 pandemic

Conference call today at 8:30 a.m. ET

Cambridge, MA — May 7, 2020 — X4 Pharmaceuticals, Inc. (Nasdaq: XFOR), a leader in the discovery and development of novel therapies targeting diseases resulting from dysfunction of the CXCR4 pathway, today reported financial results for the first quarter ended March 31, 2020 and provided a corporate update, including commentary related to the impact of the COVID-19 pandemic on the company.

“During these challenging and unprecedented times, our thoughts are with everyone affected by the COVID-19 pandemic,” said Paula Ragan, Ph.D., President and Chief Executive Officer of X4 Pharmaceuticals. “Here at X4, we continue our efforts to advance our lead product candidate, mavorixafor, through clinical development. As presented at our analyst day in April, we recently completed market research that enabled us to update and increase our estimates on the U.S. prevalence of Warts, Hypogammaglobulinemia, Infections, and Myelokathexis, or WHIM, syndrome, our lead indication for mavorixafor.”

Dr. Ragan continued, “Our first priority is the safety and wellbeing of our patients. During the pandemic, we have been regularly assessing the impact of COVID-19 on our current clinical development activities and timelines while taking measures to ensure the health and safety of our employees, patients, and healthcare providers. Our Phase 1b clinical trial of mavorixafor in patients with Waldenström’s macroglobulinemia remains on track, with initial data expected in the second half of 2020. Based on our current assessment of the impact of COVID-19 on our clinical trial sites and the pace of enrollment at certain sites, we now expect top-line Phase 3 results from our clinical trial in patients with WHIM syndrome to be delayed into 2022. Based on a similar assessment, we now expect initial data from our Phase 1b clinical trial in patients with Severe Congenital Neutropenia, or SCN, to be delayed into 2021. We will continue to work on minimizing further impact of COVID-19 on our ongoing clinical trials. We plan to provide further updates, including narrowing our guidance regarding upcoming clinical milestones, as we gain greater clarity.”





Current Impact of COVID-19 on X4 Operations and Clinical Trials

In March 2020, X4 enacted a mandatory “work from home” policy for employees with non-laboratory based work and maintained a small number of lab-based employees, compliantly working in shifts, in its Vienna, Austria research facility in order to mitigate the risk of coronavirus spreading among its personnel.

Operations: To date, the company believes that COVID-19 has had minimal effect on its ongoing business operations.
Since March 16, 2020, X4 has continued its business operations using technology and communications tools to effectively execute plans while working remotely and in virtual settings. X4 teams have continued to virtually attend meetings with investigators, regulatory authorities, partners, contractors, and investors.
Notably, X4 hosted a well-attended Virtual Analyst Day in early April, including a key opinion leader (KOL) presentation and a fireside chat. Additionally, representatives of X4 continue to attend virtual investor conferences and engage with the investment community.

Clinical Trials: To date, the company believes that the COVID-19 pandemic has had the following impact on its clinical programs:
Phase 1b Waldenström’s Trial. X4’s Phase 1b clinical trial of mavorixafor in patients with Waldenström’s macroglobulinemia remains on track, with the initial data readout still expected in the second half of 2020. The Phase 1b multi-center, open-label, dose-escalation clinical trial is designed to assess the safety and tolerability of mavorixafor in combination with ibrutinib, as well as to obtain certain efficacy signals in patients with Waldenström’s macroglobulinemia, a rare form of non-Hodgkin’s lymphoma.
Phase 1b SCN Trial. X4 is updating its guidance regarding the timing of initial data from its Phase 1b clinical trial of mavorixafor in patients with SCN. The Phase 1b clinical trial is a 14-day, proof-of-concept trial designed to assess the safety and tolerability of daily, oral mavorixafor in up to 45 patients with SCN and other selected congenital neutropenia disorders. The company expects a delay into 2021 to report initial data, which were previously expected in the second half of 2020.
Phase 3 WHIM Trial. X4 is updating its guidance on the timing of top-line data from its pivotal Phase 3 clinical trial in patients with WHIM syndrome, a rare, inherited, primary immunodeficiency disease. The 4WHIM trial is a global, 52-week, randomized, double-blind, placebo-controlled clinical trial of mavorixafor for the treatment of WHIM. Following an assessment of and input from many of its clinical trial sites, the company expects a delay into 2022 to report top-line data, which were previously expected in the second half of 2021.

First Quarter / Recent Highlights

Increased Guidance on Prevalence of WHIM at Virtual Analyst Day. X4 conducted a broad online survey of U.S. physicians to validate current prevalence estimates, and conducted additional research using artificial intelligence (AI), interrogating a database of more than 300 million anonymized patient records that spanned 10 years of insurance claims, to help identify additional likely but unconfirmed WHIM patients.
Data from the quantitative market research support an estimate of between 1,000 and 1,300 diagnosed WHIM patients in the United States today.



The research that used AI identified between 800 and 2,400 additional potential WHIM patients in the United States, which the company believes are likely to be unconfirmed and undiagnosed.
Based on this research, X4 updated guidance on its estimated range of diagnosed and undiagnosed WHIM patients in the United States to be between 1,800 and 3,700, a significant increase from its prior estimate of approximately 1,000 WHIM patients.

Results of Open-Label Extension of Phase 2 WHIM Trial to Be Presented at EHA 2020. The Phase 2 trial was an open-label, multi-center trial of mavorixafor in patients with WHIM syndrome. The trial had an initial 24-week treatment period followed by an extension phase. With its abstract accepted as a poster presentation, X4 plans to present updated data from patients participating in the extension phase of the Phase 2 trial at the Virtual Edition of the 25th European Hematology Association (EHA) Annual Congress, which will be held June 11-14, 2020.

Granted Two New U.S. Patents for Mavorixafor Composition of Matter and Method of Use. In February 2020, X4 was issued patents that are expected to provide exclusivity through 2038 for mavorixafor, the company’s lead therapeutic candidate, with additional protection for WHIM.

Expansion of Debt Facility. In March 2020, X4 amended its credit agreement with Hercules Capital, Inc. to increase X4’s potential borrowing capacity to $50 million, of which $25 million remains potentially available.

Milestone Payment from Abbisko Therapeutics. In April 2020, X4 received its first milestone payment of $3.0 million from Abbisko Therapeutics, X4’s solid tumor oncology partner for the Greater China region. This payment, tied to the closing of a financing by Abbisko, represented the first milestone stemming from the companies’ collaboration arrangement and was recognized by X4 as license revenue in the first quarter ended March 31, 2020.

First Quarter 2020 Financial Results

Cash, Cash Equivalents & Restricted Cash: X4 had $117.0 million in cash, cash equivalents and restricted cash, as of March 31, 2020. X4 continues to expect that its cash and cash equivalents will fund company operations into early 2022. In addition, X4 has $25 million of potential borrowing capacity under its amended credit agreement with Hercules. X4 continues to monitor the impact of the COVID-19 pandemic and to manage cash and working capital accordingly in case of potential changes to its business plans.
License Revenues were $3.0 million for the first quarter of 2020 related to X4’s strategic agreement with Abbisko. Cash related to this revenue was collected in April 2020 and is therefore not reflected in the $117.0 million of cash, cash equivalents and restricted cash shown above. There were no license revenues recorded in the comparable period in 2019.
Research and Development Expenses were $8.9 million for the first quarter ended March 31, 2020, as compared to $5.7 million for the comparable period in 2019.
General and Administrative Expenses were $4.7 million for the first quarter ended March 31, 2020, as compared to $4.8 million for the comparable period in 2019.
Net Loss: X4 reported a net loss of $11.1 million for the first quarter ended March 31, 2020 as compared to a net loss of $10.9 million for the comparable period in 2019.


Conference Call and Webcast



The company will host a webcast and conference call to discuss its first quarter 2020 results and provide an update on recent corporate activities today at 8:30 a.m. Eastern Time. The webcast will be accessible under “Events & Presentations” on the Investors page of the company’s website at www.x4pharma.com.

About X4 Pharmaceuticals
X4 Pharmaceuticals is a late-stage clinical biopharmaceutical company and a leader in the discovery and development of novel therapies for the treatment of diseases resulting from dysfunction of the CXCR4 pathway, with a focus on rare diseases and those with limited treatment options. The Company’s lead candidate, mavorixafor, is a first-in-class, small molecule antagonist of chemokine receptor CXCR4 being developed as a once-daily oral therapy. X4 believes that inhibition of the CXCR4 receptor creates the potential for mavorixafor to provide therapeutic benefit across a wide variety of diseases, including primary immunodeficiencies and certain types of cancer. The efficacy and safety of mavorixafor, dosed once daily, is currently being evaluated in a global Phase 3 clinical trial in patients with WHIM syndrome, and in two Phase 1b clinical trials – in combination with ibrutinib in patients with Waldenström’s macroglobulinemia, and as monotherapy in patients with Severe Congenital Neutropenia (SCN). X4 is continuing to leverage its insights into CXCR4 biology at its corporate headquarters in Cambridge, Massachusetts and at its research facility in Vienna, Austria, and is discovering and developing additional product candidates.
