Alumis ($ALMS) Stock Hub 2026: Can Psoriasis Value Survive the LUMUS Miss?

The Phase 2b LUMUS trial failed its primary and secondary endpoints in the overall systemic-lupus population. A prespecified IFNGS-high subgroup gives Alumis a regulatory question worth asking, not a validated Phase 3 path. Meanwhile, the separate psoriasis program still targets an NDA filing in Q4 2026.

One asset, two very different evidence packages

LUMUS damaged the lupus option but did not erase the Phase 3 psoriasis results. The post-drop case depends on keeping those programs separate while refusing to price the IFNGS-high hypothesis as proven.

Clinical / regulatory outlook and investor calendar
FDA/EMA end-of-Phase-2 feedback for lupus, then the planned Q4 2026 psoriasis NDA

The decisive lupus question is whether regulators accept an IFNGS-enriched Phase 3 design, dose and assay strategy. Separately, the psoriasis filing tests whether the validated ONWARD package stays on schedule. Alumis has not supplied exact dates for either event.

The constructive case

Envudeucitinib already has two positive Phase 3 psoriasis trials and supportive 48-week extension data. Alumis still expects a Q4 2026 NDA submission, held $502.3 million of cash and marketable securities at June 30, and guides the current operating plan into Q4 2027. If the psoriasis filing clears review and the IFNGS-high hypothesis wins regulatory support, the post-LUMUS equity value may be assigning too little to the lead asset and platform.

The skeptical case

LUMUS failed across the overall population, and the IFNGS-low subgroup moved in the wrong direction on BICLA. A post hoc narrative is not the same as a registrational strategy, even when the subgroup was prespecified. Psoriasis enters a competitive TYK2 market, the company is loss-making, and a future lupus Phase 3 would consume capital before its biomarker thesis is proven.

Latest position

September 8, 2026: Director Srinivas Akkaraju’s Samsara funds buy after the LUMUS readout

Two Samsara funds associated with director Srinivas Akkaraju bought 546,581 shares at a weighted average of $10.6271 and sold 96,131 at $10.5484 on September 8, 2026. The filing notes that the matched trades create short-swing profit liability under Section 16(b).

Executive summary

The short answer is that the broad lupus thesis did not survive, while the psoriasis filing path did. LUMUS was designed to test whether three envudeucitinib regimens could improve BICLA at Week 48 in a broad moderate-to-severe, autoantibody-positive systemic-lupus population receiving background standard care. All three missed. The result removes the most ambitious interpretation of the program: one oral TYK2 medicine working across an unselected SLE population.

The surviving lupus thesis is narrower. Alumis measured a four-gene type-I interferon signature at baseline and prespecified high and low subgroups. Patients classified as IFNGS-high showed stronger responses, particularly at 40 mg twice daily. Patients classified as IFNGS-low did not. A regulator could regard that as a biologically coherent enrichment strategy, or could regard it as insufficient to rescue a failed trial without further dose, assay and reproducibility work. The company intends to seek FDA and EMA feedback before defining a Phase 3.

The psoriasis evidence stands on a different foundation: two completed randomized Phase 3 trials met their primary and secondary endpoints, followed by supportive longer-duration data. The equity therefore is no longer a single all-or-nothing lupus event. It is a late-stage psoriasis program plus a damaged but not extinguished lupus option, a CNS-penetrant TYK2 candidate and a cash balance that must fund the next proof points.

Latest news
October 9, 2026

New ONWARD analyses; Q4 NDA submission remains the target

Alumis presented additional Phase 3 ONWARD analyses of investigational envudeucitinib at Fall Clinical, covering scalp disease, itch and quality of life. More than 80% maintained clear or almost-clear scalp skin at Week 48 and more than 70% maintained a DLQI score of 0 or 1. The ONWARD3 continuous-treatment analysis uses non-responder imputation in 773 patients, rather than the full 1,509-person extension population. The company reported no new long-term safety signals and reiterated a Q4 2026 NDA submission target. These analyses do not establish superiority to other medicines or reverse the separate failed LUMUS lupus readout.

01 Scenario map

Constructive

Psoriasis advances; lupus gets a credible enriched path

The NDA is submitted and accepted on schedule, the safety package remains clean, and FDA/EMA feedback supports a focused IFNGS-high Phase 3 with a manageable assay and dose.

Intermediate

Psoriasis carries the company

The NDA proceeds, but regulators demand more exploratory work before a lupus Phase 3. Alumis preserves cash by treating SLE as a lower-priority option.

Adverse

Execution compounds the LUMUS miss

The filing slips or encounters safety, CMC or labeling friction; the lupus strategy lacks regulatory support; burn and financing needs rise before commercial validation.

These are analytical scenarios, not price targets or probability estimates. The evidence needed to distinguish them is observable: filing status, regulator feedback, detailed safety data, capital allocation and the design of any new study.

What Would Falsify This Reading

Alumis is best understood as a company with one drug and two separate evidence packages: a positive Phase 3 programme in psoriasis that is heading for a filing, and a Phase 2b in lupus that missed its primary endpoint but produced a subgroup signal. Five things would show that reading to be wrong, and each is checkable against a filing, a regulator record or a company release.

  • The psoriasis application is filed on time, or slips. Alumis has guided the new drug application to the fourth quarter of 2026 without naming a day. A filing inside the window, and its acceptance afterwards, is what converts two positive Phase 3 trials into a regulatory process. A slip would put the one settled part of this company in question.
  • Regulators accept, or refuse, an interferon-signature-enriched Phase 3 in lupus. LUMUS missed overall BICLA at week 48 and the case for continuing rests on the interferon-gene-signature-high subgroup. End-of-Phase-2 feedback from the FDA and the EMA on the design, the dose and the assay is the point at which that subgroup either becomes a registrational path or does not.
  • The subgroup does not replicate. A signal found in a subgroup of a trial that missed its primary endpoint is a hypothesis. Any prospective data that fails to reproduce it, in this programme or in a competitor’s, would remove the lupus option from the reading of this page entirely.
  • The runway to the fourth quarter of 2027 is tested. $502.3 million of cash, equivalents and marketable securities at June 30, 2026 against a stated runway into the fourth quarter of 2027. A commercial build for psoriasis, or a new lupus Phase 3, would both consume that faster than the current operating plan assumes.
  • The Kaken economics change. The partnership supplies economics outside the United States without Alumis carrying the cost. An expansion, a termination or a milestone payment would each move the value of the asset without any change in the clinical evidence.

None of these is a prediction. They are the observations that would make the rest of this page wrong, listed so that a reader can check them rather than take the reading on trust.

02 The central question: what survived LUMUS?

The short answer is that the broad lupus thesis did not survive, while the psoriasis filing path did. LUMUS was designed to test whether three envudeucitinib regimens could improve BICLA at Week 48 in a broad moderate-to-severe, autoantibody-positive systemic-lupus population receiving background standard care. All three missed. The result removes the most ambitious interpretation of the program: one oral TYK2 medicine working across an unselected SLE population.

The surviving lupus thesis is narrower. Alumis measured a four-gene type-I interferon signature at baseline and prespecified high and low subgroups. Patients classified as IFNGS-high showed stronger responses, particularly at 40 mg twice daily. Patients classified as IFNGS-low did not. A regulator could regard that as a biologically coherent enrichment strategy, or could regard it as insufficient to rescue a failed trial without further dose, assay and reproducibility work. The company intends to seek FDA and EMA feedback before defining a Phase 3.

The psoriasis evidence stands on a different foundation: two completed randomized Phase 3 trials met their primary and secondary endpoints, followed by supportive longer-duration data. The equity therefore is no longer a single all-or-nothing lupus event. It is a late-stage psoriasis program plus a damaged but not extinguished lupus option, a CNS-penetrant TYK2 candidate and a cash balance that must fund the next proof points.

Merlintrader classification: ALMS is a late-stage immunology biotech with a validated psoriasis efficacy package and an unvalidated biomarker-enriched lupus strategy. Those two claims carry different evidentiary weights and stand on separate footing.

03 What Alumis is

Alumis develops targeted therapies for immune-mediated diseases. Its core scientific bet is that selective inhibition of tyrosine kinase 2, or TYK2, can modulate cytokine pathways implicated in inflammatory and autoimmune disease without directly inhibiting JAK1, JAK2 or JAK3. Envudeucitinib, formerly ESK-001, is an oral allosteric TYK2 inhibitor and the company’s lead asset. A-005 applies the same target to a brain-penetrant molecule intended for neuroinflammatory disease.

NDA-stage

Envudeucitinib in plaque psoriasis

ONWARD1 and ONWARD2 were positive Phase 3 trials. ONWARD3 supplies longer-term data. Alumis targets a Q4 2026 U.S. NDA submission.

Strategy reset

Envudeucitinib in SLE

LUMUS was negative overall. A prespecified IFNGS-high subgroup supports regulatory discussion, not a confirmed pivotal design.

Early clinical

A-005 in Parkinson’s disease

Phase 1 target-engagement and CNS-penetration observations support a planned Phase 2 biomarker trial in the first half of 2027.

The current company also reflects its 2025 merger with ACELYRIN. One acquired program, lonigutamab, was placed into a strategic-alternatives process in 2026 and its associated acquired in-process R&D asset was impaired by $41.8 million in Q2. That history matters because it shows that the balance sheet and share count fund a broader organization than envudeucitinib alone, while management is actively narrowing capital allocation.

04 LUMUS design: what the trial was built to answer

Alumis reports that LUMUS Part A (NCT05966480) enrolled 408 adults with moderately to severely active, autoantibody-positive SLE on background standard-of-care therapy. The topline efficacy table lists denominators of 101 for placebo, 102 for envudeucitinib 40 mg twice daily, 99 for 20 mg twice daily and 103 for 20 mg once daily—405 patients in total. The sponsor materials do not reconcile the three-patient difference in that table. Treatment lasted 48 weeks before an open-label extension.

The primary endpoint was BICLA response at Week 48. BICLA requires improvement in disease activity without clinically meaningful worsening in other components and without prohibited treatment changes. Key secondary measures included SRI-4, CLASI-50, low lupus disease activity state, corticosteroid reduction, active-joint reduction and flares. The trial therefore tested broad clinical activity rather than a laboratory surrogate alone.

The interferon-gene-signature analysis was not invented after topline failure. Baseline blood RNA sequencing classified participants using a four-gene signature—HERC5, IFI27, IFIT1 and RSAD2—and the high/low analysis was prespecified. However, prespecification does not automatically control every multiplicity issue or replace a successful primary endpoint. The exact assay, cutoff, missing-data handling and regulatory acceptability must be locked before a pivotal study.

Design boundary: LUMUS can generate a credible enriched-population hypothesis because IFNGS was measured at baseline and prespecified. It cannot by itself establish that an IFNGS-high Phase 3 will succeed or that the observed subgroup effect is sufficient for registration.

05 Overall results: the primary endpoint failed

Week-48 endpointPlacebo40 mg BID20 mg BID20 mg QD
BICLA response35.7%41.0%42.2%40.0%
Adjusted difference vs. placebo—+6.2 points+6.9 points+4.7 points

SRI-4 response40.4%52.7%52.1%60.9%
SRI-4 nominal p-value—0.04170.09090.0028

The BICLA confidence intervals for each treatment difference crossed zero and none approached statistical significance. That is the decisive overall-population result. The SRI-4 table contains nominal p-values below 0.05 for two regimens, but Alumis explicitly states that the trial did not achieve its secondary endpoints in the overall population. Those nominal values do not count as successful secondary endpoints, because the prespecified testing hierarchy and multiplicity rules govern formal success.

Alumis attributes the weak overall separation partly to an IFNGS-low proportion of about 40%, higher than the roughly 30% it expected, and to a high placebo response in that group. This may explain the outcome, but explanation and proof are different. Randomization exposed the drug to the population the protocol enrolled; an unfavorable mix is still part of the trial result.

06 IFNGS-high signal—and the IFNGS-low warning

Prespecified subgroupPlacebo40 mg BID20 mg BID20 mg QD
IFNGS-high BICLA (n=63 / 60 / 62 / 64)28.6%52.6%49.5%40.7%
Adjusted BICLA difference—+24.0 points+21.3 points+11.6 points
IFNGS-high SRI-433.1%60.9%57.8%67.7%
IFNGS-low BICLA (n=38 / 42 / 37 / 39)47.5%24.4%30.0%39.0%

The high-signature BICLA pattern is the strongest argument for continuing in SLE: separation increased with dose, several secondary measures moved in the same direction, and pharmacodynamic data showed the greatest type-I interferon-pathway inhibition at the highest dose. It is also biologically aligned with the central role of interferon signaling in a substantial subset of lupus patients.

The low-signature result is not a neutral footnote. Placebo BICLA reached 47.5%, while every active arm was lower. Small subgroup sizes create wide uncertainty and the pattern does not prove harm, but it means the overall miss is not explained merely by dilution from nonresponders. The Phase 3 decision must address whether enrichment is scientifically and operationally robust, whether 40 mg twice daily is acceptable for chronic use, and whether the commercial assay can reproduce the research classification.

Evidence rule: the IFNGS-high subgroup is hypothesis-strengthening because it was prespecified, dose-coherent on BICLA and mechanistically plausible. It remains unconfirmed because the parent trial failed and no independent prospective study has replicated the selection strategy.

07 Safety: encouraging topline, incomplete granularity

Alumis reports that envudeucitinib was generally well tolerated with no new safety signals. Incidences of treatment-emergent adverse events, Grade 3 or higher events, drug-related events, discontinuations, serious adverse events, serious infections, and embolic or thrombotic events were lower on active treatment than placebo. No major adverse cardiovascular events, extended MACE or malignancies were reported in any arm.

Those statements are useful but sponsor-reported and topline. The release and deck do not provide complete event counts, exposure-adjusted rates, laboratory abnormalities or a detailed dose-by-dose table. The 40 mg twice-daily regimen is particularly important because it delivered the clearest subgroup signal and the most target engagement. A Phase 3 dose choice requires the full safety dataset, not only the directional summary.

The broader TYK2 class still carries clinical considerations. The current U.S. label for deucravacitinib, an approved TYK2 comparator, includes warnings and precautions covering serious infections, tuberculosis screening, malignancy, muscle enzyme elevations, liver enzyme monitoring in known or suspected liver disease, immunizations and uncertainty about whether TYK2 inhibition may share some adverse-reaction associations seen with JAK inhibition. That label does not define envudeucitinib’s safety, but it shows the regulatory benchmark for chronic TYK2 therapy.

08 Psoriasis: the asset still has a positive Phase 3 package

ONWARD1 and ONWARD2 were randomized Phase 3 trials in moderate-to-severe plaque psoriasis. Alumis reported that both met all primary and secondary efficacy endpoints. At Week 16, the average across the two studies was 74% for PASI 75 and 59% for static Physician’s Global Assessment 0/1. The detailed Week-24 results were PASI 90 of 68.0% in ONWARD1 and 62.1% in ONWARD2, with PASI 100 of 41.0% and 39.5%, respectively.

ONWARD3 follows patients longer. Among 773 people receiving continuous envudeucitinib for up to 48 weeks, the sponsor reported PASI 90 of 75% and PASI 100 of 54%. In a broader nonresponder-imputation analysis across 890 randomized envudeucitinib patients, the corresponding 48-week rates were 66% and 47%. Both presentations are valid for their stated populations, but they are not interchangeable.

The safety profile across the Phase 3 program was described as consistent with earlier studies, with no new signals in ONWARD3. Complete regulatory review will examine the integrated efficacy, safety, manufacturing and pharmacology package. Positive topline trials make the psoriasis case materially stronger than the lupus case, but they do not guarantee filing acceptance or approval.

09 The psoriasis NDA and commercial test

Alumis continues to target submission of a U.S. New Drug Application in Q4 2026. A submitted NDA is not the same as an accepted filing, approved label or commercial launch. After submission, investors still need the FDA’s filing decision, review classification, possible information requests, manufacturing readiness, final labeling and any postmarketing commitments.

Commercially, envudeucitinib would enter an established field that includes biologics, oral deucravacitinib and other systemic therapies. The value proposition must therefore combine efficacy depth, durability, safety, convenience, access and net price. Cross-trial PASI comparisons are unreliable because study populations, placebo performance, imputation and timing differ. Head-to-head evidence is more informative where available, and payer positioning may matter as much as headline PASI rates.

The key separation: LUMUS did not invalidate the psoriasis efficacy dataset. It can still affect sentiment, capital allocation and perceptions of the molecule’s breadth, but the FDA will evaluate the psoriasis NDA on the psoriasis package.

A-005 is designed to penetrate the central nervous system while inhibiting TYK2. Alumis says Phase 1 showed maximal peripheral target inhibition, CNS penetration and acceptable tolerability in healthy volunteers. A biomarker trial in Parkinson’s disease could show target engagement in patients, but it is not a conventional efficacy trial and should not be valued as proof of disease modification.

11 Kaken partnership: useful economics, limited geography

Kaken Pharmaceutical holds exclusive rights to develop and commercialize envudeucitinib in Japan for dermatology indications and has options in rheumatology and gastrointestinal diseases. Alumis retained rights outside Japan and in indications not covered or exercised under the agreement.

Upfront payment$20 millionReceived under the collaboration

Regulatory and option milestonesUp to $36 millionConditional, not cash on hand
Commercial milestonesUp to ¥15.5 billionDependent on future achievements
Royalties in JapanLow double digits into the twentiesBased on future net sales and agreement tiers

The partnership supplies external validation and reduces some Japan-specific development burden. It does not finance global commercialization, remove U.S. regulatory risk or make the contingent milestone totals equivalent to current cash.

Management says the June 30 liquidity can fund the current operating plan into Q4 2027. That runway is company guidance, not a guarantee. It depends on trial scope, NDA and launch spending, any lupus Phase 3, pipeline prioritization, collaboration receipts and working-capital changes. A post-LUMUS program reset could reduce or increase spending depending on the chosen path.

The balance sheet did not show a funded-debt line at June 30, although lease liabilities were about $4.8 million current and $31.6 million noncurrent. Debt-light does not mean dilution-free: late-stage development and commercialization can require more capital before product cash flows become material.

Open the primary source for both charts

For the six months ended June 30, 2026, operating cash use was $168.582 million, equivalent to about $28.10 million per month by division by six. That historical average is not a forecast: working capital, trial spending and a new lupus program can change future use. Reported June liquidity of $502.3 million divided by that historical monthly rate corresponds to about 17.9 months from June 30, before future spending changes. Management’s current-plan guidance into Q4 2027 is a separate forward-looking assessment. The first-half net loss of $235.274 million also contains non-cash items, including $41.824 million of impairment and $26.612 million of equity compensation; net loss is therefore not the cash-burn measure. Q2 Form10-Q.

13 Capital structure and dilution

The share-count and liquidity statements have their own dates. A valuation must account for future development spending, equity compensation and any financing; the third-party market capitalization shown above is not an independently calculated enterprise value or the value of an approved product.

In January 2026 the company sold approximately 20.30 million shares at $17.00, generating about $345.1 million gross and $324.4 million net proceeds. In March it established an at-the-market program with up to $300 million of capacity; no shares had been sold under that program through June 30. The unused facility is financial flexibility and a dilution overhang, not evidence that a sale will occur.

Options, restricted stock units and other equity awards can expand the economic share base. A fully diluted valuation should use the latest footnote tables and option strike prices rather than the voting-share count alone. The sharp price decline also changes the efficiency and signaling cost of any future equity raise.

14 Valuation framework after the drop

A disciplined sum-of-the-parts framework separates four components:

  • Psoriasis risk-adjusted value: probability of filing, acceptance, approval, label, launch timing, penetration, net price, margin and patent life.
  • Lupus option value: probability that regulators accept enrichment, a new Phase 3 succeeds, and a usable diagnostic pathway reaches practice.
  • A-005 and early pipeline: modest until patient-level biomarker and efficacy evidence accumulates.
  • Net financial resources: cash and securities less liabilities and the expected burn required to reach each milestone.

The market reaction implies a large reduction in lupus optionality and/or confidence in the asset platform. It does not reveal which component investors sold. A low price relative to the previous close is not itself evidence of undervaluation.

15 Competitive landscape

In plaque psoriasis, envudeucitinib must compete with highly effective injectable biologics, oral deucravacitinib, other oral systemics and a development pipeline of next-generation agents. Commercial differentiation may require a balance of deep skin clearance, durable response, convenient dosing, acceptable monitoring and payer access. A superior result in an indirect chart does not establish superiority.

In SLE, competitors include approved biologics directed at B-cell and interferon biology, background immunosuppressants and other oral pathway inhibitors in development. Alumis’ proposed advantage would be an oral therapy paired with a biologically selected population. Its disadvantage is that the selection hypothesis now carries the burden of rescuing an overall negative trial.

The approved deucravacitinib label also establishes a real regulatory and commercial TYK2 benchmark. Envudeucitinib may differ in dose, pharmacology, efficacy or safety, but those distinctions need comparative evidence and a final label before they become durable commercial claims.

16 Principal risks

  • Clinical replication: the IFNGS-high effect may shrink or disappear in a new trial.
  • Regulatory design: FDA or EMA may reject the proposed assay, cutoff, dose, endpoint or single-subgroup strategy.
  • Psoriasis review: positive efficacy does not eliminate integrated-safety, manufacturing, pharmacology or labeling risk.
  • Commercial competition: strong existing options may pressure access, net price and adoption.
  • Safety and chronic dosing: rare or exposure-related events may emerge with larger datasets or longer follow-up.
  • Financing: the current runway ends before mature commercial cash flow is assured, and the ATM creates potential dilution.
  • Concentration: much of the late-stage value rests on one molecule across indications.
  • Execution: simultaneous NDA work, potential lupus redesign, A-005 development and pipeline prioritization stretch management and capital.

17 Catalyst and evidence calendar

Second half of 2026Two-year Phase 2 psoriasis safety data, according to company guidance; exact date not provided.
Q4 2026Targeted U.S. NDA submission for envudeucitinib in moderate-to-severe plaque psoriasis.
Date not specifiedEnd-of-Phase-2 interactions with FDA and EMA regarding the IFNGS-enriched SLE strategy, dose and enrollment criteria.
First half of 2027Planned initiation of the A-005 Phase 2 biomarker trial in Parkinson’s disease.
Into Q4 2027Company-guided cash runway under the current operating plan; not a clinical catalyst.

A meeting request, planned submission or guided trial start becomes a confirmed event only when the company or regulator supplies a dated milestone.

18 Bottom line

LUMUS is a material clinical failure. The overall SLE population missed BICLA and the company says it missed the secondary endpoints; the adverse IFNGS-low pattern prevents a simple “good trial with the wrong mix” reading. The IFNGS-high signal is sufficiently coherent to justify a regulatory conversation because it was prespecified, dose-related on BICLA and supported by pharmacodynamics. It is not sufficiently proven to treat a Phase 3 as de-risked.

The investment debate now pivots back to psoriasis. ONWARD1, ONWARD2 and ONWARD3 provide a substantially stronger evidence package, and the Q4 2026 NDA target remains intact. Alumis also retains meaningful liquidity, but its loss and cash use show that the balance sheet is a runway, not a floor under the stock.

The honest question for ALMS: can a positive psoriasis registration package create enough value before the company must finance the next wave of development, while the lupus program proves—rather than assumes—that IFNGS enrichment works?

Primary sources

Source documents include the SEC-filed LUMUS release, the LUMUS data deck, the ClinicalTrials.gov record NCT05966480, Alumis’ Q2 2026 Form 10-Q and Q2 update, and the SEC-filed ONWARD1/2 topline, detailed Phase 3 data and ONWARD3 update. The current FDA SOTYKTU label is used only as a class benchmark, not as evidence about envudeucitinib. Market data are a dated secondary-source snapshot. Cross-trial comparisons are not head-to-head evidence.

Frequently asked questions about $ALMS

What did the LUMUS trial show?

LUMUS was a Phase 2b trial of envudeucitinib in 408 patients with moderate-to-severe autoantibody-positive systemic lupus erythematosus. It missed its primary endpoint, overall BICLA response at week 48. The company points to a signal in the subgroup of patients with a high interferon gene signature. A subgroup finding in a trial that missed its primary endpoint is a hypothesis to be tested prospectively, not a result.

Does Alumis still have a psoriasis programme?

Yes, and it is the part of the company the lupus miss did not touch. Envudeucitinib has two positive Phase 3 trials in plaque psoriasis with supportive 48-week extension data, and Alumis has guided a new drug application to the fourth quarter of 2026. The two programmes share a molecule but not an evidence package, and reading across from one to the other is the main way this company gets misjudged.

What is envudeucitinib?

An oral allosteric TYK2 inhibitor, still investigational. Allosteric means it binds away from the enzyme’s active site, which is the design choice intended to give selectivity for TYK2 over the related JAK enzymes and therefore a different safety profile from the broader JAK inhibitors.

How much cash does Alumis have?

$502.3 million of cash, cash equivalents and marketable securities at June 30, 2026, as reported in the Form 10-Q filed on August 13, 2026, with a cash runway guided into the fourth quarter of 2027 on the company’s current operating plan. That plan predates any decision on a new lupus Phase 3 or a commercial build in psoriasis.

What is the next thing to watch?

Two things, neither with a date. Whether the psoriasis new drug application is submitted inside the guided fourth-quarter 2026 window, and what the FDA and the EMA say at end-of-Phase-2 about running a lupus Phase 3 enriched for the interferon gene signature, including which dose and which assay would be acceptable. Alumis has not published timing for either.

Biotechnology securities can lose substantial or all value. A positive subgroup in an overall negative trial does not establish efficacy, regulatory acceptance or Phase 3 success. Positive Phase 3 results do not guarantee NDA acceptance, approval, commercial availability, reimbursement, adoption or sales. Trial results apply to the studied population, design, endpoints and follow-up.

Financial and market figures are dated and can change.
