Rhea-AI Filing Summary

Compass Pathways plc (CMPS) filed an 8-K to disclose that its pivotal Phase 3 COMP005 study met its primary endpoint in treatment-resistant depression (TRD). In the randomized, double-blind trial (n = 258 across 32 U.S. sites), a single 25 mg dose of COMP360 psilocybin produced a statistically significant reduction in Montgomery-Åsberg Depression Rating Scale (MADRS) scores versus placebo at week 6 (mean difference �3.6 points; 95% CI [�5.7, �1.5]; p < 0.001). Safety, reviewed by the independent DSMB on 19 June 2025, was consistent with prior studies and showed no new or unexpected adverse signals, including suicidality.

COMP005 has three parts, with Parts A (through week 6) now unblinded, Part B blinded to week 26, and Part C open-label through week 52. The parallel COMP006 trial (planned n = 568) compares two fixed dosing regimens and remains blinded. The company expects to release 26-week data for COMP005 after all COMP006 participants complete Part A; 26-week COMP006 data are targeted for H2 2026.

The positive read-out strengthens CMPS’s regulatory pathway, but the FDA has not yet reviewed the data, full safety assessments are pending, and additional capital will likely be required to complete development and pursue commercialization. Forward-looking statements highlight clinical, regulatory, and financing risks.

Compass Pathways plc (CMPS) ha presentato un modulo 8-K per comunicare che il suo studio pivotale di Fase 3 COMP005 ha raggiunto l'endpoint primario nella depressione resistente al trattamento (TRD). Nel trial randomizzato e in doppio cieco (n = 258 in 32 centri negli Stati Uniti), una singola dose da 25 mg di COMP360 psilocibina ha prodotto una riduzione statisticamente significativa dei punteggi nella Montgomery-Åsberg Depression Rating Scale (MADRS) rispetto al placebo alla settimana 6 (differenza media �3,6 punti; IC 95% [�5,7, �1,5]; p < 0,001). La sicurezza, valutata dal comitato indipendente DSMB il 19 giugno 2025, è risultata coerente con studi precedenti e non ha evidenziato nuovi o inattesi segnali avversi, inclusa la suicidalità.

COMP005 è composto da tre parti: la Parte A (fino alla settimana 6) è stata ora svelata, la Parte B rimane in cieco fino alla settimana 26, mentre la Parte C è in aperto fino alla settimana 52. Il trial parallelo COMP006 (n previsto = 568) confronta due regimi di dosaggio fissi ed è ancora in cieco. L'azienda prevede di pubblicare i dati a 26 settimane per COMP005 dopo che tutti i partecipanti a COMP006 avranno completato la Parte A; i dati a 26 settimane di COMP006 sono attesi per la seconda metà del 2026.

I risultati positivi rafforzano il percorso regolatorio di CMPS, ma la FDA non ha ancora esaminato i dati, sono in corso valutazioni complete sulla sicurezza e probabilmente sarà necessario ulteriore capitale per completare lo sviluppo e procedere alla commercializzazione. Le dichiarazioni prospettiche evidenziano rischi clinici, regolatori e finanziari.

Compass Pathways plc (CMPS) a déposé un formulaire 8-K pour annoncer que son étude pivot de phase 3 COMP005 a atteint son critère principal dans la dépression résistante au traitement (TRD). Lors de l'essai randomisé en double aveugle (n = 258 dans 32 sites américains), une dose unique de 25 mg de psilocybine COMP360 a entraîné une réduction statistiquement significative des scores sur l'échelle de dépression Montgomery-Åsberg (MADRS) par rapport au placebo à la semaine 6 (différence moyenne �3,6 points ; IC à 95 % [�5,7, �1,5] ; p < 0,001). La sécurité, examinée par le DSMB indépendant le 19 juin 2025, était conforme aux études précédentes et n'a montré aucun nouveau signal indésirable ou inattendu, y compris la suicidabilité.

COMP005 comprend trois parties : la partie A (jusqu'à la semaine 6) est désormais déblindée, la partie B reste en aveugle jusqu'à la semaine 26, et la partie C est en ouvert jusqu'à la semaine 52. L'essai parallèle COMP006 (n prévu = 568) compare deux schémas posologiques fixes et reste en aveugle. La société prévoit de publier les données à 26 semaines pour COMP005 une fois que tous les participants de COMP006 auront terminé la partie A ; les données à 26 semaines de COMP006 sont prévues pour le second semestre 2026.

Les résultats positifs renforcent la voie réglementaire de CMPS, mais la FDA n'a pas encore examiné les données, les évaluations complètes de sécurité sont en attente, et des capitaux supplémentaires seront probablement nécessaires pour achever le développement et poursuivre la commercialisation.

Compass Pathways plc (CMPS) reichte eine 8-K-Meldung ein, um bekanntzugeben, dass die entscheidende Phase-3-Studie COMP005 ihren primären Endpunkt bei therapieresistenter Depression (TRD) erreicht hat. In der randomisierten, doppelblinden Studie (n = 258 an 32 US-Standorten) führte eine einmalige 25 mg-Dosis COMP360 Psilocybin zu einer statistisch signifikanten Reduktion der Montgomery-Åsberg Depression Rating Scale (MADRS)-Punkte gegenüber Placebo in Woche 6 (mittlere Differenz �3,6 Punkte; 95% KI [�5,7, �1,5]; p < 0,001). Die Sicherheit, geprüft vom unabhängigen DSMB am 19. Juni 2025, entsprach vorherigen Studien und zeigte keine neuen oder unerwarteten unerwünschten Signale, einschließlich Suizidalität.

COMP005 besteht aus drei Teilen: Teil A (bis Woche 6) wurde nun entblindet, Teil B bleibt bis Woche 26 verblindet, und Teil C ist offen bis Woche 52. Die parallele COMP006-Studie (geplante n = 568) vergleicht zwei feste Dosierungsschemata und bleibt verblindet. Das Unternehmen plant, 26-Wochen-Daten für COMP005 zu veröffentlichen, nachdem alle COMP006-Teilnehmer Teil A abgeschlossen haben; 26-Wochen-Daten von COMP006 sind für die zweite Hälfte 2026 vorgesehen.

Das positive Ergebnis stärkt den regulatorischen Weg von CMPS, aber die FDA hat die Daten noch nicht geprüft, vollständige Sicherheitsbewertungen stehen aus, und wahrscheinlich wird zusätzliches Kapital benötigt, um die Entwicklung abzuschließen und die Kommerzialisierung voranzutreiben. Zukunftsgerichtete Aussagen weisen auf klinische, regulatorische und finanzielle Risiken hin.

Positive
  • Primary endpoint met in pivotal Phase 3 COMP005 with p < 0.001, materially increasing regulatory probability of success.
  • No new safety concerns reported by DSMB, reducing perceived psychedelic risk profile.
  • Large, multi-site randomized design (258 patients, 32 U.S. centers) enhances data credibility and external validity.
Negative
  • Only 6-week data; durability through 26 and 52 weeks remains unknown.
  • Regulatory approval still contingent on positive COMP006 results and FDA review.
  • High cash burn implies likely future equity raises, creating dilution risk for shareholders.

Insights

TL;DR: First Phase 3 win in TRD is clinically meaningful; de-risks program but regulatory and funding hurdles remain.

Efficacy: A �3.6 MADRS difference with p < 0.001 in a 258-patient, placebo-controlled trial is robust; effect size is within the 2�4-point range often viewed as clinically important in depression registrational studies.
Safety: DSMB confirmation of no new safety issues, specifically suicidality, removes a key FDA concern with psychedelics.
Regulatory Pathway: With one positive pivotal trial, CMPS now needs a confirmatory COMP006 win; FDA typically requires two adequate and well-controlled studies. The single-dose design of COMP005 also complements the multiple-dose arm in COMP006, potentially strengthening labeling discussions.
Valuation Impact: Probability-of-success for COMP360 in TRD should rise materially (e.g., from ~30 % to ~50 % in many DCF models), providing potential multi-hundred-million-dollar uplift to NPV.
Risks: Full 26-week durability data are not yet available; any attenuation could temper payer uptake. Cash burn remains high; additional equity or partnership financing is probable in 2025-26.

TL;DR: Event is positive but still preliminary; execution, cash, and regulatory timing drive risk-reward.

Impact to shares is likely favorable near-term given scarcity of late-stage psychedelic assets. However, catalysts gap until COMP006 read-outs (H2 2026) could re-introduce volatility. Cash runway (~$200 m at last report) covers < 18 months of operations; equity dilution risk is high. FDA could request additional safety data, notably on cardiovascular and psychiatric adverse events, extending timelines. Position sizing should reflect binary regulatory outcomes and liquidity constraints.

Item 8.01Other Events.
Compass Pathways plc (the “Company”) announced today the successful achievement of the primary endpoint in the ongoing Phase 3 COMP005 trial, the first of two Phase 3 trials evaluating COMP360, a synthetic, proprietary formulation of psilocybin, for treatment-resistant depression (TRD). The primary endpoint is the difference in change from baseline in the Montgomery-Åsberg Depression Rating Scale (MADRS) scores between the active treatment group and the placebo group at week 6. A single dose of COMP360 25 mg versus placebo demonstrated a highly statistically significant reduction in symptom severity with a p-value of p<0.001 and a clinically meaningful difference of -3.6 in change at the primary endpoint. The Company plans to discuss these preliminary COMP005 data with the U.S. Food and Drug Administration (FDA) which has not yet reviewed the data.

Key COMP005 Findings:

Efficacy Data (MADRS): Single dose of COMP360 25 mg versus placebo with a mean treatment difference of -3.6 points, 95% CI[ -5.7, -1.5]; p<0.001

Safety Data (statement dated June 19, 2025 provided by the DSMB chair): Based on the latest review of the data for the 005 and 006 studies, safety findings are consistent with previous studies of COMP360 and there are no new or unexpected safety findings. From this review of the data, there is no evidence of a clinically meaningful imbalance between treatment arms in suicidality in either study.

The COMP360 program aims to evaluate the safety and efficacy of COMP360 psilocybin, a synthetic, proprietary formulation of psilocybin under investigation for difficult-to-treat mental health conditions. There are two pivotal Phase 3 trials, COMP005 and COMP006, evaluating the efficacy of COMP360 for treatment-resistant depression (TRD).

The ongoing COMP005 trial is a randomized, double-blinded, placebo-controlled study, which has dosed 258 participants with moderate-to-severe depression across 32 sites in the United States and aims to assess the efficacy and safety of a single dose of 25 mg COMP360 versus placebo for reducing symptom severity in TRD. The trial is comprised of three parts: Part A - which has recently concluded – and was blinded through 6 weeks; Part B, which remains blinded through week 26; and Part C, which contains an open-label treatment part from week 26 to 52.

The COMP006 trial, running in parallel to COMP005, is a randomized, double-blinded study with 568 planned participants from North America and Europe and aims to compare the safety and efficacy of two fixed doses, taken three weeks apart, of 25 mg COMP360 to 10 mg COMP360 and 1 mg COMP360. The trial is comprised of three parts: Part A, which is blinded through 9 weeks, Part B which remains blinded through week 26, and Part C, which contains an open-label treatment part from week 26 to 52.

Compass Pathways anticipates sharing 26-week data for COMP005 once all participants in the COMP006 trial have completed part A of the COMP006 trial. The 26-week data from COMP006 is expected in the second half of 2026.

Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, as amended. Any statements, other than statements of historical fact, including statements regarding the Company’s plans and expectations regarding the Company’s Phase 3 trials in TRD, including the Company’s expectations regarding the time periods during which the 26-week results of the two Phase 3 trials will become available; the potential for the pivotal Phase 3 program in TRD to support regulatory filings and approvals; any implication that past results will be predictive of future results; and any other statements containing the words “expects,” “anticipates,” “plans,” and similar expressions, are forward-looking statements. These forward-looking statements are based on the Company’s current intentions, beliefs and expectations regarding future events. The Company cannot guarantee that any forward-looking statement will be accurate. Investors should realize that if underlying assumptions prove inaccurate or unknown risks or uncertainties materialize, actual results could differ materially from the Company’s expectations, including uncertainties associated with risks related to clinical development which is a lengthy and expensive process with uncertain outcomes, and therefore the Company’s clinical trials may be delayed or terminated and may be more costly than expected; the full results and safety data from this Phase 3 study in TRD or the results and safety data from the Company’s second Phase 3 study in TRD,



COMP006, may not be consistent with the preliminary results to date; the Company’s need for substantial additional funding to achieve its business goals and if the Company is unable to obtain this funding when needed and on acceptable terms, the Company could be forced to delay, limit or terminate its clinical trials; the Company’s efforts to obtain marketing approval from the applicable regulatory authorities in any jurisdiction for the Company’s investigational COMP360 psilocybin treatment may be unsuccessful; and those risks and uncertainties described under the heading “Risk Factors” in the Company’s most recent annual report on Form 10-K or quarterly report on Form 10-Q and in other reports the Company has filed with the U.S. Securities and Exchange Commission (“SEC”), which are available on the SEC’s website at www.sec.gov. Investors are, therefore, cautioned not to place undue reliance on any forward-looking statement. Any forward-looking statement speaks only as of the date of this Form 8-K, and, except as required by law, the Company does not undertake to update any forward-looking statement to reflect new information, events or circumstances.
