Summary of Risk Factors

Below is a summary of the material factors that make an investment in our common stock speculative or risky. This summary does not address all of the risks that we face. Our business involves significant risks that may have a material adverse effect on our business, financial condition, results of operations, prospects and stock price. These risks are more fully described below and include, among others:

We are a clinical stage biopharmaceutical company with a history of losses. We expect to continue to incur significant losses for the foreseeable future and may never achieve or maintain profitability, which could result in a decline in the market value of our common stock.
In our initial Phase 1 clinical trial for SZN-043, treatment-related adverse events have been observed, and if these findings are present in patients with severe alcohol-associated hepatitis and do not represent acceptable safety, we could require additional capital to complete our clinical trial and development efforts for SZN-043 or we may need to delay or abandon development of SZN-043.
We will need substantial additional funds to advance development of product candidates of our Wnt therapeutics platform, and we cannot guarantee that we will have sufficient funds available in the future to develop and commercialize our current or potential future product candidates.
None of our product candidates have received regulatory approval; our ability to achieve and sustain profitability depends on obtaining regulatory approval and successfully commercializing product candidates, either alone or with collaborators.
If any current or future product candidate, after it begins clinical trials or receives marketing approval, demonstrates undesirable safety or tolerability side effects or safety concerns, our ability to market and derive revenue from the product candidate could be compromised.
We have incurred significant operating losses since inception and anticipate that we will incur continued losses for the foreseeable future.
Any future equity or debt issuances or other financing transactions may have dilutive or adverse effects on our existing stockholders.
We rely on third parties to conduct our preclinical studies and our clinical trials, and those third parties may not perform satisfactorily.
Our clinical development activities could be delayed or otherwise adversely affected for various reasons.
The manufacturing of our product candidates is complex. We and our third-party manufacturers may encounter difficulties in production. If we encounter any such difficulties, our ability to supply our product candidates for clinical trials or, if approved, for commercial sale, could be delayed or halted entirely.
We face competition from entities that have developed or may develop product candidates for the treatment of the diseases that we may target, including companies developing novel treatments and therapeutic platforms. If these companies develop therapeutics or product candidates more rapidly than we do, or if their therapeutics or product candidates are more effective or have fewer side effects, our ability to develop and successfully commercialize product candidates may be adversely affected.
If we are unable to maintain proper and effective internal controls over financial reporting, the accuracy and timeliness of our financial reporting and the market price of our common stock may be adversely affected.

33


Our future growth may depend, in part, on our ability to operate in foreign markets, where we would be subject to additional regulatory burdens and other risks and uncertainties.
Our business, operations and clinical development plans and timelines could be adversely affected by the effects of health epidemics, natural disasters and other events on the manufacturing, clinical trial and other business activities performed by us or by third parties with whom it conducts business, including contract manufacturers, CROs, shippers and others.
To the extent we enter into any other collaborations, we may depend on such collaborations for the development and commercialization of our product candidates. If those collaborations are not successful, we may not be able to capitalize on the market potential of our product candidates.
Collaborations are complex and time-consuming to negotiate and document, and if we fail to enter into new strategic relationships, our business, financial condition, commercialization prospects and results of operations may be materially adversely affected.
If we are unable to obtain or protect intellectual property rights related to our technology and current or future product candidates, or if our intellectual property rights are inadequate, we may not be able to compete effectively.
Some intellectual property that we have in-licensed may have been discovered through government funded programs and thus may be subject to federal regulations such as “march-in” rights, certain reporting requirements and a preference for U.S.-based companies. Compliance with such regulations may limit our exclusive rights and limit our ability to contract with non-U.S. manufacturers.
Clinical development includes a lengthy and expensive process with an uncertain outcome, we may have negative results and results of earlier studies and trials may not be predictive of future trial results.
We have conducted our clinical trial for our product candidate outside of the United States. However, the FDA and other foreign equivalents may not accept data from such trials, in which case its development plans will be delayed, which could materially harm its business.
A few stockholders, including one of our directors, control the voting rights with respect to a large number of shares of our common stock and could exercise their voting power in a manner that adversely affects us or our stockholders.

Risks Related to Our Business

We are a clinical stage biopharmaceutical company with a history of losses. We expect to continue to incur significant losses for the foreseeable future and may never achieve or maintain profitability, which could result in a decline in the market value of our common stock.

We are a clinical stage biopharmaceutical company with a history of losses. Since our inception, we have devoted substantially all of our resources to research and development, preclinical studies, clinical trials, building our management team and building our intellectual property portfolio, and have incurred significant operating losses. Since its inception, we have devoted substantially all of its resources to research and development, preclinical studies, building its management team and building its intellectual property portfolio, and has incurred significant operating losses. Substantially all of our losses have resulted from expenses incurred in connection with our research and development programs and from general and administrative costs associated with our operations. To date, we have not generated any revenue from product sales, and have not sought or obtained regulatory approval for any product candidate. Furthermore, we do not expect to generate any revenue from product sales for the foreseeable future, and we expect to continue to incur significant operating losses for the foreseeable future due to the cost of research and development, preclinical studies and clinical trials and the regulatory approval process for our current and potential future product candidates.

We expect our net losses to increase substantially as our lead product candidate, SZN-043, advances through clinical development. However, the amount of our future losses is uncertain. Our ability to achieve or sustain profitability, if ever, will depend on, among other things, successfully developing product candidates, continuing clinical trials for SZN-043, successful development and testing of SZN-413 through our partnership with Boehringer Ingelheim International GmbH, or BI, obtaining regulatory approvals to market and commercialize product candidates, manufacturing any approved products on commercially reasonable terms, entering into potential future alliances, establishing a sales and marketing organization or suitable third-party alternatives for any approved product and raising sufficient funds to finance business activities. Our ability to achieve or sustain profitability, if ever, will depend on, among other things, successfully developing product candidates, obtaining regulatory approvals to market and commercialize product candidates, manufacturing any approved products on commercially reasonable terms, entering into potential future alliances, establishing a sales and marketing organization or suitable third-party alternatives for any approved product and raising sufficient funds to finance business activities. If we, or our current and potential future collaborators, are unable to commercialize one or more of our product candidates, or if sales revenue from any product candidate that receives approval is insufficient, we will not achieve or sustain profitability, which could have a material and adverse effect on our business, financial condition, results of operations and prospects. If we, or our potential future collaborators, are unable to commercialize one or more of our product candidates, or if sales revenue from any product candidate that receives approval is insufficient, we will not achieve or sustain profitability, which could have a material and adverse effect on our business, financial condition, results of operations and prospects.

In our initial Phase 1 clinical trial for SZN-043, treatment-related adverse events have been observed, and if these findings are present in patients with severe alcohol-associated hepatitis and do not represent acceptable safety, we could require additional capital to complete our clinical trial and development efforts for SZN-043 or we may need to delay or abandon development of SZN-043.

The Phase 1a clinical trial for SZN-043 was completed in February 2024, but Grade 1 and 2 treatment-related asymptomatic transaminase elevations were present in several subjects dosed with SZN-043. The transaminase elevations for these subjects resolved spontaneously, and no serious adverse events were observed during the study. We intend to further analyze available clinical data and monitor future clinical studies to understand and mitigate, if possible, for these observations. If these observations are present and represent unacceptable safety in the intended population of patients with severe alcohol-associated hepatitis, or AH, we may need to pause the trials to perform additional pre-clinical experiments, causing delays in our development plans and requiring additional capital to resume and complete our development efforts and clinical trial for SZN-043. If we are unable to safely continue the trials for SZN-043 and resolve these observations, development of SZN-043 may be substantially delayed or abandoned and adversely affect our financial condition and results of operations.

We will need substantial additional funds to advance development of product candidates of our Wnt therapeutics platform, and we cannot guarantee that we will have sufficient funds available in the future to develop and commercialize our current or potential future product candidates.

The development of biopharmaceutical product candidates is capital-intensive. If SZN-043 or potential future product candidates advance through preclinical studies and clinical trials, we will need substantial additional funds to expand our development, regulatory, manufacturing, marketing and sales capabilities. If SZN-1326, SZN-043 or potential future product candidates enter and advance through preclinical studies and clinical trials, we will need substantial additional funds to expand our development, regulatory, manufacturing, marketing and sales capabilities. We have used substantial funds to develop our Wnt therapeutics platform, SZN-043 and other product candidates and we will require significant funds to continue to develop our platform, continue the clinical trial for SZN-043 and to conduct further research and development, including preclinical studies and clinical trials. We have used substantial funds to develop our Wnt therapeutics platform, SZN-1326, SZN-043 and other product candidates and we will require significant funds to continue to develop our platform and conduct further research and development, including preclinical studies and clinical trials.

To date, we have primarily financed our operations through the sale of equity securities. Until such time as we can generate sufficient revenue from sales of our product candidates, if ever, we expect to finance our operations through public or private equity offerings, debt financings or other capital sources, including government grants, potential collaborations with other companies or other strategic transactions. In February 2022, we entered into a purchase agreement and a registration rights agreement with Lincoln Park Capital Fund, LLC, or Lincoln Park, pursuant to which we have the right, but not the obligation, to sell to Lincoln Park, and Lincoln Park is obligated to purchase up to $50.0 million of our common stock from time to time over a 36-month period, subject to certain conditions and limitations. We may not be able to receive any or all of the funds from Lincoln Park because of the limitations, restrictions,

35


requirements, events of default and other provisions contained in the purchase agreement that could limit our ability to cause Lincoln Park to purchase our common stock. If our stock price decreases, we also may not be able to sell shares to Lincoln Park at all or in amounts sufficient to obtain necessary financing. If our stock price drops, we also may not be able to sell shares to Lincoln Park at all or in amounts sufficient to obtain necessary financing. In December 2022, we entered into an at-the-market sales agreement with Guggenheim Securities, LLC, or Guggenheim, in connection with a shelf registration statement on Form S-3 filed in December 2022, to issue and sell our common stock with an aggregate maximum offering price of $23.0 million under an at-the-market offering program. To date we have not sold any shares of common stock under the sales agreement. Given the volatility in the capital markets, we may not be willing or able to raise equity capital through such at-the-market offering. We may, therefore, need to turn to other sources of funding that may have terms that are not favorable to us, or further reduce our business operations due to capital constraints.

We may be unable to raise additional funds or to enter into such agreements or arrangements on favorable terms, or at all. Our ability to raise additional funds may be adversely impacted by potential worsening global economic conditions and the disruptions to, and volatility in, the credit and financial markets in the United States, and worldwide. Our ability to raise additional funds may be adversely impacted by potential worsening global economic conditions and the disruptions to, and volatility in, the credit and financial markets in the United States, and worldwide resulting from the COVID-19 pandemic and the conflict between Russia and Ukraine. The overall impact of these events on our business may be significantly affected by the actions of U.S. and foreign governments. These events and actions could result in severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates, and uncertainty about economic stability. If the equity and credit markets deteriorate, it may make any necessary debt or equity financing more difficult, more costly and more dilutive.

If we are unable to raise additional capital in sufficient amounts, in a timely manner or on terms acceptable to us, we may have to significantly delay, scale back, or discontinue the development of our product pipeline or other research and development initiatives. We also could be required to seek collaborators for our product pipeline and any future product candidates at an earlier stage than otherwise would be desirable or on terms that are less favorable than might otherwise be available or relinquish or license on unfavorable terms our rights to our product pipeline and any future product candidates in markets where we otherwise would seek to pursue development or commercialization ourselves.

Our future capital requirements and the period for which we expect existing resources to support our operations may vary significantly from our projections. Our monthly spending levels vary based on new and ongoing research and development and other corporate activities. Because the length of time and activities associated with successful research and development of product candidates is highly uncertain, we are unable to estimate the actual funds we will require for development and any approved marketing and commercialization activities. The timing and amount of our operating expenditures will depend largely on:

the timing and progress of preclinical and clinical development of SZN-043, SZN-413 and other potential future product candidates;
the timing and progress of the development of our Wnt therapeutics platform;
the price and pricing structure that we are able to obtain from our third-party contract manufacturers to manufacture our preclinical study and clinical trial materials and supplies;
the extent to which prices for supplies and materials increase due to inflationary pressures and labor market constraints;
the number and scope of preclinical and clinical programs we decide to pursue;
our ability to maintain our current licenses, research and development programs and to establish new collaborations;
the progress of the development efforts of parties with whom we may in the future enter into collaboration and research and development agreements;
the costs involved in obtaining, maintaining, enforcing and defending patents and other intellectual property rights;
the impact of the health epidemics on our business;
the cost and timing of regulatory approvals; and
our efforts to enhance operational systems and hire additional personnel, including personnel to support development of our product candidates and satisfy our obligations as a public company.

If we are unable to raise sufficient capital when needed, our business, financial condition and results of operations will be harmed, and we will need to significantly modify our operational plans. We may also have to liquidate assets, and the value we receive for any assets in liquidation or dissolution could be significantly lower than the values reflected in our financial statements.

None of our product candidates have received regulatory approval; our ability to achieve and sustain profitability depends on obtaining regulatory approval and successfully commercializing product candidates, either alone or with collaborators.

36


Before obtaining regulatory approval for the commercial distribution of our product candidates, we or a collaborator must conduct extensive preclinical studies, followed by clinical trials to demonstrate the safety, purity and potency, or efficacy of our product candidates in humans. There is no guarantee that the U.S. Food and Drug Administration, or the FDA, or other regulatory authorities will permit us to conduct clinical trials. Further, we cannot be certain of the timely completion or outcome of our preclinical studies and cannot predict if the FDA or other regulatory authorities will accept our proposed clinical programs, our clinical protocols or if the outcome of our preclinical studies will ultimately support the further development of our preclinical programs or testing in humans. Further, we cannot be certain of the timely completion or outcome of our preclinical studies and 43 cannot predict if the FDA or other regulatory authorities will accept our proposed clinical programs, our clinical protocols or if the outcome of our preclinical studies will ultimately support the further development of our preclinical programs or testing in humans. As a result, we cannot be sure that we will be able to submit Investigational New Drugs, or INDs, or similar applications for our proposed clinical programs on the timeline we expect, if at all, and cannot be sure that submission of INDs or similar applications will result in the FDA or other regulatory authorities allowing clinical trials for any of our product candidates to begin.

We are subject to the risks of failure inherent in the development of product candidates based on novel approaches, targets and mechanisms of action. There is no guarantee that we will be able to proceed with clinical development of our product candidates or that our product candidates will demonstrate a clinical benefit once we further advance these candidates. Accordingly, you should consider our prospects in light of the costs, uncertainties, delays and difficulties that we have encountered and that are frequently encountered by clinical stage biopharmaceutical companies such as us. Accordingly, you should consider our prospects in light of the costs, uncertainties, delays and difficulties frequently encountered by preclinical stage biopharmaceutical companies such as us.

We may not be able to access the financial resources to continue development of, or to enter into any collaborations for, SZN-043 or any potential future product candidates. This may be exacerbated if we experience any issues that delay or prevent regulatory approval of, or our ability to commercialize, a product candidate, such as:

negative or inconclusive results from our preclinical or clinical trials (including as described above) or the clinical trials of others for product candidates similar to ours, leading to a decision or requirement to conduct additional preclinical studies or clinical trials or abandon any or all of our programs;
product-related side effects experienced by participants in our clinical trials (such as the asymptomatic transaminase elevations discussed above) or by individuals using drugs or therapeutic antibodies similar to ours, including immunogenicity;
delays in submitting IND applications or comparable foreign applications, or delays or failures to obtain the necessary approvals from regulators to commence a clinical trial, or a suspension or termination of a clinical trial once commenced;
conditions imposed by the FDA or other regulatory authorities regarding the scope or design of our clinical trials;
delays in enrolling research subjects in clinical trials;
high drop-out rates of research subjects;
inadequate supply or quality of product candidate components or materials or other supplies necessary for the conduct of our clinical trials;
chemistry, manufacturing and control, or CMC, challenges associated with manufacturing and scaling up manufacturing of biologic product candidates to ensure consistent quality, stability, purity and potency among different batches used in clinical trials;
greater-than-anticipated clinical trial costs;
poor potency or effectiveness of our product candidates during clinical trials;
unfavorable FDA or other regulatory authority inspection and review of a clinical trial or manufacturing site;
failure of us or Boehringer Ingelheim International GmbH to adequately perform under the Collaboration and License Agreement;
failure of our third-party contractors or investigators to comply with regulatory requirements or otherwise meet their contractual obligations in a timely manner, or at all;
delays and changes in regulatory requirements, policies and guidelines; or
the FDA or other regulatory authorities interpreting our data differently than it does.

Further, we and our current and potential future collaborator may never receive approval to market and commercialize any product candidate. Even if we or our current and potential future collaborator obtains regulatory approval, the approval may be for targets, disease indications or patient populations that are not as broad as were intended or desired or may require labeling that includes significant use or distribution restrictions or safety warnings. Even if we or a potential future collaborator obtains regulatory approval, the approval may be for targets, disease indications or patient populations that are not as broad as were intended or desired or may require labeling that includes significant use or distribution 44 restrictions or safety warnings. We or our current and potential future collaborator may be subject to post-marketing testing requirements to maintain regulatory approval. We or a potential future collaborator may be subject to post-marketing testing requirements to maintain regulatory approval.

37


SZN-043, SZN-413 and any other of our future product candidates that are tested in humans may not demonstrate the safety, purity and potency, or efficacy, necessary to become approvable or commercially viable.

We may ultimately discover that SZN-043 and SZN-413 do not possess certain properties that we believe are beneficial for therapeutic effectiveness and safety. For example, although SZN-043 exhibited encouraging results in animal studies, they may not demonstrate the same properties in humans and may interact with human physiology in unforeseen, ineffective or harmful ways, as shown by the observations of asymptomatic transaminase elevations discussed above. For example, although SZN-043 has exhibited encouraging results in animal studies, including improvement of liver function in multiple animal models of liver injury, it may not demonstrate the same properties in humans and may interact with human biological systems in unforeseen, ineffective or harmful ways. As a result, we may never succeed in developing a marketable product based on any of our current or future product candidates. If SZN-043, SZN-413 or any of our potential future product candidates prove to be ineffective, unsafe or commercially unviable, our entire pipeline could have little, if any, value, which could require us to change our focus and approach to antibody-based discovery and development and materially and adversely affect our business, financial condition, results of operations and prospects.

We may not be successful in our efforts to use and expand our Wnt therapeutics platform to build a pipeline of product candidates.

A key element of our strategy is to use and expand our Wnt therapeutics platform to discover and develop a portfolio of Wnt product candidates that can facilitate the repair and/or regeneration of damaged tissue for patients suffering from a variety of severe diseases. Although our research and development efforts to date have resulted in the discovery and development of SZN-043, SZN-413 and other potential product candidates, our current product candidates may not be safe or effective therapeutics and we may not be able to develop any successful product candidates. Our platform is evolving and may not reach a state at which building a pipeline of product candidates is possible. Even if we are successful in building our pipeline of product candidates, the potential product candidates that we identify may not be suitable for clinical development or generate acceptable clinical data, including as a result of being shown to have unacceptable toxicity or other characteristics that indicate that they are unlikely to be products that will receive marketing approval from the FDA or other regulatory authorities or achieve market acceptance. Observations of asymptomatic transaminase elevations in clinical trial of SZN-043 could also impair our ability to build and expand our Wnt platform if we are unable to successfully resolve those observations. If we do not successfully develop and commercialize product candidates, we will not be able to generate product revenue in the future.

Although we intend to explore other therapeutic opportunities, in addition to the product candidates that we are currently developing, we may fail to identify viable new product candidates for clinical development for a number of reasons. If we fail to identify additional potential product candidates, our business could be materially harmed.

Although a substantial amount of our efforts will focus on the planned clinical trials and potential approval of our existing product candidates and other potential product candidates we are evaluating, a key element of our strategy is to discover, develop and potentially commercialize additional products beyond our current product candidates to treat various conditions and in a variety of therapeutic areas. We intend to do so by investing in our own drug discovery efforts, exploring potential strategic alliances for the development of new products and in-licensing technologies. Identifying new investigational medicines requires substantial technical, financial and human resources, whether or not any investigational medicines are ultimately identified. Even if we identify investigational medicines that initially show promise, we may fail to successfully develop and commercialize such products for many reasons, including the following:

the research methodology used may not be successful in identifying potential investigational medicines;
competitors may develop alternatives that render its investigational medicines obsolete;
investigational medicines it develops may nevertheless be covered by third parties’ patents or other exclusive rights;
an investigational medicine may, on further study, be shown to have harmful side effects or other characteristics that indicate it is unlikely to be effective or otherwise does not meet applicable regulatory criteria;
it may take greater human and financial resources than we will possess to identify additional therapeutic opportunities for our product candidates or to develop suitable potential product candidates through internal research programs, thereby limiting our ability to develop, diversify and expand our product portfolio;
an investigational medicine may not be capable of being produced in commercial quantities at an acceptable cost, or at all; and
an approved product may not be accepted as safe and effective by trial patients, the medical community or third-party payors.

Because we have limited financial and human resources, we intend to initially focus on research programs and product candidates for a limited set of indications. As a result, we may forgo or delay pursuit of opportunities with other product candidates or for other

38


indications that later prove to have greater commercial potential or a greater likelihood of success. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities.

Accordingly, there can be no assurance that we will ever be able to identify additional therapeutic opportunities for our product candidates or to develop suitable potential product candidates through internal research programs, which could materially adversely affect our future growth and prospects. We may focus our efforts and resources on potential product candidates or other potential programs that ultimately prove to be unsuccessful.

The market may not be receptive to our current or potential future product candidates, and we may not generate any revenue from the sale or licensing of our product candidates.

Even if regulatory approval is obtained for a product candidate, including SZN-043, we may not generate or sustain revenue from sales of approved products. Market acceptance of our current and potential future product candidates, if approved, will depend on, among other factors:

the timing of its receipt of any marketing and commercialization approvals;
the terms of any approvals and the countries in which approvals are obtained;
the safety and efficacy of our product candidates;
the prevalence and severity of any adverse side effects associated with our product candidates;
limitations or warnings contained in any labeling approved by the FDA or other regulatory authority;
relative convenience and ease of administration of our product candidates;
the success of its physician education programs;
the availability of coverage and adequate government and third-party payor reimbursement;
the pricing of our products, particularly as compared to alternative treatments; and
availability of alternative effective treatments for the disease indications our product candidates are intended to treat and the relative risks, benefits and costs of those treatments.

If any product candidate we commercialize fails to achieve market acceptance, it could have a material and adverse effect on our business, financial condition, results of operations and prospects.

If any current or future product candidate, after it begins clinical trials or receives marketing approval, demonstrates undesirable safety or tolerability side effects or safety concerns, our ability to market and derive revenue from the product candidate could be compromised.

Undesirable side effects caused by SZN-043, SZN-413 or any potential future product candidate could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other regulatory authorities. It is also possible that there will be side effects associated with the testing or use of our product candidates. Results of our clinical trials could reveal a high and unacceptable severity and prevalence of these side effects. In such an event, our trials could be suspended or terminated and the FDA or other regulatory authorities could order us to cease further development of or deny approval of a product candidate for any or all targeted indications. Such side effects could also affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. For example, certain researchers have noted that therapeutics targeting the Wnt pathway may lead to tumor formation or proliferation as a result of the downstream impacts of Wnt signaling. To date, we have not observed any such tumor formation with SZN-043 in our preclinical toxicology studies and clinical trial, but there can be no guarantee that our current or future product candidates will not result in tumor formation. To date, we have not observed any such tumor formation with SZN-1326 or SZN-043 in our preclinical toxicology studies, but there can be no guarantee that our current or future product candidates will not result in tumor formation. Any of these occurrences or failure to resolve the findings related to SZN-043 may materially and adversely affect our business and financial condition and impair our ability to generate revenues.

Further, clinical trials by their nature use a sample of the potential patient population. With a limited number of patients and limited duration of exposure, rare and severe side effects of a product candidate may only be uncovered when a significantly larger number of patients are exposed to the product candidate or when patients are exposed for a longer period of time.

In the event that any of our current or potential future product candidates receive regulatory approval and we or others identify undesirable side effects caused by one of these products, any of the following adverse events could occur, which could result in the loss of significant revenue to us and materially and adversely affect our results of operations and business:
