Current report

In October 2025, we presented translational data at the European Society of Medical Oncology (ESMO) Congress 2025 in Berlin, Germany and at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics in Boston, Massachusetts. Data presented build on preclinical data previously presented in April 2025 at the American Association for Cancer Research (AACR) Annual Meeting in Chicago.

Current report

The poster presentations at the ESMO and AACR-NCI-EORTC meetings provide deeper insights into the pharmacodynamic responses of tumors to micvotabart pelidotin as well as micvotabart pelidotin’s unique mechanism of action (MOA) and its potential to exert anti-tumor activity through three mechanisms: direct tumor cell killing, bystander killing and immunogenic cell death. These translational findings highlight micvotabart pelidotin’s effects on tumor microenvironment (TME) remodeling, immune activation and tumor infiltration, further reinforcing the potential benefit of micvotabart pelidotin as both monotherapy and in combination with anti-PD-1 therapy.

Current report

Observations include changes in circulating tumor DNA (ctDNA) tumor fraction (TF) after treatment with micvotabart pelidotin to the vast majority of 37 clinical samples tested. Notably, reduction in ctDNA TF after treatment with micvotabart pelidotin, particularly in HNSCC and at the 5.4 mg/kg dose, supports a positive molecular response to micvotabart pelidotin and strengthens rationale for continued development of this tumor type and dose in the monotherapy dose expansion study. Additionally, features observed in nonclinical samples of the stromal architecture detected using digital pathology may correlate with sensitivity to micvotabart pelidotin - a finding that may be unique compared to tumor cell surface targeting ADCs, due to micvotabart pelidotin’s targeting of a non-cellular structural component of the tumor ECM.

Current report

Additional translational data supporting micvotabart pelidotin’s MOA indicate this ADC binds very specifically to EDB+FN in the TME, an important trait for the non-cellular tumor ECM targeting MOA, locally delivering the ADC close to the malignant cells for cancer cell killing after extracellular linker cleavage. Data also indicate micvotabart pelidotin binds strongly to EDB+FN, which enables the ADC to stay anchored in the TME longer allowing more time for extracellular linker cleavage by proteases. In vitro data presented indicate micvotabart pelidotin’s linker can be cleaved extracellularly via specific cathepsins and pH conditions that exist in the TME, which are necessary conditions for the bystander effect.

Current report

Multiple posters supported micvotabart pelidotin’s ability to induce immunogenic cell death as a mouse analog of micvotabart pelidotin stimulated immune response in tumors that had been refractory to anti-PD1 and synergistic antitumor activity when combined with anti-PD1.

Comparison of the Nine Months Ended September 30, 2025 and 2024

Current report

The following table summarizes our results of operations for the nine months ended September 30, 2025 and 2024 (in thousands):

Current report

The Company’s future cash flows are dependent on key variables such as its ability to secure additional sources of funding in the form of public or private financing of equity or debt or collaboration agreements or a combination of these. While we remains optimistic to obtain additional funding in the near future, the current available cash, cash equivalents and short-term investments, will not be sufficient to fund our operations over the next 12 months from the date of this Quarterly Report on Form 10-Q. This condition raises substantial doubt about our ability to continue as a going concern for one year from the date the unaudited condensed consolidated financial statements are issued.

Previous report

In April 2025, we presented preclinical data at the 2025 American Association for Cancer Research (AACR), Annual Meeting in Chicago. We observed broad anti-tumor activity for micvotabart pelidotin across ten solid tumor indications in PDX models, attributed to EDB+FN target expression, proteolytic activity for micvotabart pelidotin linker cleavage and tumor responsiveness to the optimized cytotoxic Auristatin0101 payload. The preclinical data is summarized below:

Previous report

45% of models demonstrated strong to very strong tumor growth inhibition (TGI%) activity (70%<TGI<90% or TGI>90% respectively), with only 25% of models showing no response (TGI<25%).

Previous report

PDX models with very strong activity (TGI>90%) were found across nine out of ten solid tumor indications.

Previous report

Complete responses to micvotabart pelidotin (tumor volume reached 0mm 3 for at least two consecutive measurements) were found across several tumor indications, consistent with previous analysis.

Previous report

micvotabart pelidotin was observed to be well-tolerated (3mg/kg, Q4Dx4).

Previous report

We also performed differential gene expression analysis, which enabled us to identify gene signatures linked to anti-tumor activity consistent with our extracellular ADC hypothesis. We observed that enzyme and tumor stroma gene signatures were the gene sets with the greatest number of differentially expressed genes. Further, the preclinical data shows upregulation of certain proteases that may contribute to increased linker cleavage and subsequent increased anti-tumor activity for micvotabart pelidotin, supporting our extracellular hypothesis.

Previous report

We also conducted preclinical studies combining a mouse analog of micvotabart pelidotin with anti-PD-1 therapy. The combination of a mouse analog of micvotabart pelidotin with anti-PD-1 therapy inhibited EMT6 tumor growth and improved survival compared to either treatment alone, suggesting potential benefit for combination therapy to deepen anti-tumor responses in solid tumors. The preclinical studies combining a mouse analog of micvotabart pelidotin with anti-PD-1 therapy is summarized below:

Previous report

Monotherapy of mouse analog of micvotabart pelidotin inhibited dose-dependent tumor outgrowth of EDB+FN expressing EMT6 tumors and was well-tolerated at 6 mg/kg.

Previous report

The mouse analog of micvotabart pelidotin boosted the immune response by activating dendritic cells and increasing CD45+ immune cell infiltration, including PD-1+ T cells, into tumors, transforming EMT6 tumors into immune-infiltrated, "hot" tumors.

Previous report

Significant TGI observed with mouse analog of micvotabart pelidotin (TGI=94%) and anti-PD-1 therapy (TGI=54%) as monotherapies.

Previous report

The combination of the mouse analog of MICVO and anti-PD-1 therapy resulted in TGI of 91% and complete response was seen in 9/15 animals – greater tumor regression and clearance than either treatment alone.

Previous report

Mouse analog of micvotabart pelidotin in combination with anti-PD1 therapy induced lasting immunological memory, enhancing tumor clearance and protecting against tumor recurrence in rechallenged mice.

Previous report

The preclinical data indicated micvotabart pelidotin alone may be eliciting immune responses in previously unresponsive tumors, as observed with the infiltration of T cells into the tumor, representing potential for micvotabart pelidotin to drive immunogenic cell death. Together, these preclinical data further support the three-pronged mechanism of action of micvotabart pelidotin driving anti-tumor activity via direct tumor killing, bystander effect and immunogenic cell death.

Previous report

The following table summarizes our results of operations for the six months ended June 30, 2025 and 2024 (in thousands):

Previous report

The Jumpstart Our Business Startups Act of 2012, or the JOBS Act, permits an “emerging growth company” to take advantage of an extended transition period to comply with new or revised accounting standards. We are an “emerging growth company,” as defined in the JOBS Act. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies.
Reworded paragraphs (34)

Previous wording

Our product candidate, micvotabart pelidotin, formerly referred to as PYX-201, is an investigational novel antibody-drug conjugate (ADC) that uniquely targets Extradomain-B Fibronectin (EDB+FN), a non-cellular structural component within the tumor extracellular matrix (ECM). The tumor ECM is a complex network of fibrous proteins and molecules with unique composition that play an important role in cell development and tumor growth and in some instances, in supporting metastasis. The fibronectin strands within the ECM give the tumor shape and support the clustering of tumor cells.

Previous wording

We initiated Part 1 dose escalation phase of PYX-201-102 covering multiple tumor types with an aim to identify the Recommended Phase 2 Dose (RP2D) of micvotabart pelidotin in combination with pembrolizumab. Currently, we are enrolling and dosing patients to clear the three doses that will be tested in combination with pembrolizumab. During Part 1 dose escalation, we anticipate testing a fixed dose of pembrolizumab in combination with 3 different doses of micvotabart pelidotin ranging from 3.6 mg/kg – 5.4 mg/kg IV Q3W. Pembrolizumab (standard dose at 200 mg IV) will be given with escalating doses of micvotabart pelidotin with a starting dose of 3.6 mg/kg IV every 3 weeks (Q3W). Upon clearance of the initial dose level of 3.6 mg/kg IV Q3W by the Dose Escalation and Steering Committee (DESC), and depending on observed safety data, we may escalate to 4.4 mg/kg IV Q3W of micvotabart pelidotin with 200 mg IV of pembrolizumab, with a potential of dosing at 5.4 mg/kg IV Q3W of micvotabart pelidotin with 200 mg IV of pembrolizumab. We aim to select a dose of micvotabart pelidotin in combination with pembrolizumab by mid-year 2025, which will guide our discussion with the FDA about potential RP2D for further combination study.

Dose escalation remains ongoing.

Previous wording

Concurrently to the Part 1 dose escalation and assuming each dose clears the escalation step, the Phase 1/2 combination study will evaluate micvotabart pelidotin and pembrolizumab in patients with 1L and 2L+ R/M HNSCC. We expect to enroll approximately 20 patients, which will be enrolled for each dose in their respective backfill cohort upon clearance of the dose by the DESC. Pembrolizumab (standard dose at 200 mg IV) will be given with escalating doses of micvotabart pelidotin with a starting dose of 3.6 mg/kg IV every 3 weeks, followed by dose of 4.4 mg/kg IV Q3W, if DESC clears it and then a dose of 5.4 mg/kg IV Q3W, if DESC clears it. We anticipate having preliminary data on at least a subset of these R/M HNSCC patients in the second half of 2025. Timing of data availability from the full recruitment and dosing of R/M HNSCC patients is dependent on the timing of activation of additional clinical trial sites and patient enrollment. Further guidance on anticipated timing of the full preliminary data readout will be provided in the fall of 2025.

As of June 30, 2025, we had approximately $90.4 million in cash, cash equivalents, restricted cash and short-term investments.

We are also a “smaller reporting company,” meaning that the market value of our shares held by non-affiliates is less than $700 million and our annual revenues were less than $100 million during the most recently completed fiscal year. We may rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. Specifically, as a smaller reporting company, we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report on Form 10-K and have reduced disclosure obligations regarding executive compensation, and, similar to emerging growth companies, if we are a smaller reporting company with less than $100 million in annual revenues, we would not be required to obtain an attestation report on internal control over financial reporting issued by our independent registered public accounting firm.
