Are there any upcoming catalysts (e.g., interim data readouts, conference presentations) that could further move the stock in the near term?

Short‑Answer: The only concrete catalyst that can be reasonably anticipated from the information you’ve provided is the next data read‑out from the 160‑mg cohort of the TUSCANY Phase 1/2 trial (and any associated presentation at a major oncology conference). No specific dates have been announced in the release, but the progression of this trial will generate the next “near‑term” catalyst that could move the stock.

Below is a detailed breakdown of what to watch for, why it matters, and when you might see the news hit the market.

1. Immediate Context from the News Release

Item	What the Release Tells Us
Safety Review Committee (SRC) decision	The SRC endorsed escalation to 160 mg – the highest dose being evaluated – and reported no dose‑limiting toxicities (DLTs) to date. This is a positive safety signal that removes a major early‑stage hurdle.
Current trial status	Enrollment is now open for the 160‑mg cohort. The trial is a front‑line triple‑drug regimen (Tuspetinib + two other agents) in a disease setting that has not yet been defined in the summary (but presumably a hematologic or solid‑tumor indication).
Stage of development	Phase 1/2 – early‑stage, but the data will be closely scrutinized because it is the first time a 160‑mg dose is being tested in humans for this regimen.
What the news does NOT give	– Specific timeline for cohort enrollment completion. – Planned interim‑analysis dates. – Planned conference presentation or press‑release dates.

Bottom‑line: The news itself is a modest “positive catalyst” (it will likely give the stock a short‑term boost because a higher dose is now being pursued), but the real drivers will be the first efficacy/safety read‑out from this cohort and any public presentation of those results.

2. Likely Near‑Term Catalysts

Catalyst	Why It’s Important	Typical Timing / What to Watch For
Interim data read‑out from the 160‑mg cohort (e.g., safety, pharmacokinetics, early efficacy signals)	Provides the first proof‑of‑concept that a higher dose is safe and potentially more efficacious. If data are favorable, they can: • Support a rapid dose‑selection decision for the Phase 2 expansion. • Prompt the company to file an IND amendment or initiate a Phase 2/3 design. • Generate partnership or licensing interest.	Typical Phase 1/2 trials often schedule an interim analysis after the first 15‑30 patients have completed ≥ 2 cycles of therapy. For a trial that opened enrollment for 160 mg on 6 Aug 2025, expect first‑patient‑in data for the cohort in mid‑Q4 2025, with an interim safety/PK read‑out late Q4 2025 to early Q1 2026. The exact date will be disclosed via a company press release or in the SEC Form 8‑K.
Presentation at a major oncology conference (e.g., ESMO 2025 in October, ASCO 2025/2026, AACR 2025/2026)	Conference abstracts provide a “public‑market” platform that can generate analyst coverage, boost visibility, and often precede a press release with data. A strong abstract can generate pre‑market hype and potentially a short‑term rally.	ESMO 2025 (October 2025) is the first major conference after the August release; ASCO 2025 has already passed (June 2025) but a post‑meeting data package could be released after ESMO. The company may file an abstract for ESMO 2025 or for the 2026 ASCO Meeting (June 2026) depending on how quickly data mature. Watch the company’s investor relations page for abstract submission announcements (usually ~2‑3 months before the meeting).
Regulatory milestone (e.g., IND amendment to expand the 160‑mg cohort or pre‑IND meeting with the FDA)	If the 160‑mg cohort demonstrates an acceptable safety profile, the company may file an IND amendment to broaden the dosing or add a second indication. This can trigger a “clinical‑development” milestone that is often reflected in the stock price.	Usually follows the first safety/PK data set; expect an FDA‑meeting request early‑mid‑2026 if the interim data look favorable. Look for SEC 8‑K filings titled “FDA Meeting Request” or “IND amendment.”
Strategic partnership or licensing	A positive 160‑mg read‑out can attract strategic partners (big pharma or biotech) who may sign a co‑development or out‑license deal, which historically produces a 10‑30 % stock uplift.	If data look compelling, partner negotiations can occur within 3–6 months after the first read‑out, so mid‑2026 is the plausible window. Check for press releases titled “Collaboration” or “Licensing.”

3. Timeline Snapshot (Based on Typical Development Milestones)

Timeline	Expected Event	Typical Trigger
Immediate (0–2 months)	News release (6 Aug 2025) → short‑term bump (increased interest).
~Q4 2025 (Oct‑Dec)	First‐patient‑in (FPI) for 160‑mg cohort, dose‑escalation safety data (likely still “no DLTs”).	Company may issue a brief update or press release summarizing the FPI safety.
Late Q4 2025 – early Q1 2026 (Jan‑Feb 2026)	Interim safety/PK/early efficacy data from first 15–30 pts.	Potential press release and SEC 8‑K.
Oct 2025 (ESMO conference)	Abstract submission/acceptance for 2025 ESMO (likely by late June).	Conference abstract posted; presentation on 18–22 Oct 2025.
Mid‑2026 (Q2–Q3)	Full interim analysis (≥ 2 cycles of therapy, tumor response if applicable) → data read‑out.	Potential catalyst for stock, could be positive or negative.
Late 2026	Regulatory filing (e.g., IND amendment) or partnering if data are strong.	SEC filing (8‑K), press release.

4. What to Watch for in Real‑Time

Source	What to Look For	Where/When
Company Press Releases	“Enrollment Update,” “Interim Data,” “Conference Abstract Submission.”	Investor Relations page, Business Wire/GlobeNewswire.
SEC Filings (8‑K / 10‑Q)	“Safety Update,” “FDA/IRB approvals,” “License/Collaboration.”	SEC Edgar → monitor Aptose (APTO) 8‑K filings.
ClinicalTrials.gov	Updates to NCT ID (enrollment status, first patient date).	Search for TUSCANY trial; check Study Status.
Conference Programs	ESMO 2025 (Oct), ASCO 2026 (June), AACR 2025/2026, ASH 2025 (Dec).	Review abstract calendars (e.g., ESMO 2025 abstract tracker).
Analyst Coverage	Analysts may post “catalyst timeline” in research notes.	Look at broker notes, FactSet/Thomson Reuters alerts.

5. Bottom‑Line Take‑aways

The only concrete near‑term catalyst from the information you supplied is the future data read‑out from the 160‑mg cohort of the TUSCANY trial.
No explicit dates for interim or final data have been disclosed, so you will need to monitor press releases and SEC filings for the exact timing.
Potential conference presentations (particularly ESMO 2025 in October and later ASCO 2026) are the most likely public‑market venues where the data will be showcased.
If the interim data are positive, expect a stock‑price bump (10‑30 % depending on magnitude) as investors re‑price the upside (potential Phase 2/3 expansion, partnership interest). Conversely, negative data could trigger a sell‑off.
Action steps for investors:
- Add Aptose (APTO) to your watchlist and set an alert for any 8‑K filing or press release in Q4 2025–Q2 2026.
- Monitor clinicaltrials.gov for updates on NCT number (once you have it) to see when enrollment for the 160‑mg cohort completes.
- Review ESMO abstract listings around July–August 2025 for any Aptose abstract – a submission indicates that data will be presented in October 2025.

Bottom line: No specific upcoming catalyst is identified in the current news release; however, the next data read‑out from the 160‑mg cohort (likely late 2025–early 2026) and any conference presentation (especially at ESMO 2025) constitute the primary near‑term catalysts that could move the stock in the short‑term. Keep a close eye on the company’s press releases and SEC filings for the exact dates.
