Nasus Pharma Announces Positive Interim Results from Phase 2 Clinical Study of NS002 Intranasal Epinephrine Powder
Rhea-AI Summary
Nasus Pharma (NYSE: NSRX) reported positive interim Phase 2 results for NS002, an intranasal epinephrine powder. The open-label study enrolled 50 healthy adults with allergic rhinitis. Key pharmacokinetic advantages versus intramuscular EpiPen®: Cmax 655 pg/ml vs 548 pg/ml, Tmax 10.8 min vs 15 min, and 91% vs 67% of participants reached the 100 pg/ml plasma threshold at 5 minutes. Early exposure (AUC 0–10 min) was 55 h*pg/ml vs 32 h*pg/ml. Repeat dosing with or without nasal allergic challenge showed consistent PK benefits. Safety: NS002 was well-tolerated with no serious adverse events and mostly mild, local TEAEs. Full Phase 2 results expected by end of Q1 2026; pivotal study planned for Q4 2026.
Positive
- Cmax 655 pg/ml for NS002 versus 548 pg/ml for EpiPen
- Tmax faster at 10.8 minutes versus 15 minutes for EpiPen
- 91% of NS002 subjects reached 100 pg/ml at 5 minutes versus 67% with EpiPen
- Early exposure (AUC 0–10 min) higher at 55 h*pg/ml versus 32 h*pg/ml
- No serious adverse events reported across 50 subjects; mostly mild local TEAEs
- Consistent pharmacokinetic advantages on repeat dosing with or without nasal challenge
Negative
- Results are interim and based on an open-label study; full Phase 2 data pending end of Q1 2026
- Study population was healthy adults with allergic rhinitis, not patients experiencing anaphylaxis
- Small sample size of 50 subjects limits broad generalizability

Historical Context
| Date | Event | Sentiment | Move | Catalyst |
|---|---|---|---|---|
| 2025-12-22 | Shareholder letter | Positive | -6.6% | Outlined 2025 milestones, IPO proceeds use, and NS002 development timelines. |
| 2025-10-08 | Partnership expansion | Positive | +0.8% | Expanded Aptar agreements to support NS002 device, supply and regulatory work. |
| 2025-09-02 | Conference participation | Neutral | -0.7% | Announced virtual presentation at H.C. Wainwright investor conference. |
| 2025-08-26 | Listing milestone | Positive | +0.5% | Celebrated NYSE American listing with bell ceremony highlighting NS002 focus. |
| 2025-08-14 | IPO financing | Positive | +0.6% | Closed IPO raising $10M to fund NS002 development and corporate needs. |
Recent news often saw modest reactions, with one notable divergence where a positive shareholder letter coincided with a larger one-day decline.
Over the past six months, Nasus Pharma advanced NS002 and its corporate profile with an IPO in August 2025 raising $10 million, NYSE American listing, and expanded Aptar collaboration to support NS002 development and commercialization. Subsequent updates included conference participation and a 2025 shareholder letter outlining Phase 2 progress and timelines. That letter highlighted the interim analysis now reported, linking today’s Phase 2 interim results to previously signposted milestones and the broader NS002 development strategy.
Market Pulse Summary
The stock moved -7.5% in the session following this news. A negative reaction despite favorable Phase 2 interim data would contrast with prior largely aligned responses to positive corporate events such as the $10 million IPO and Aptar collaboration expansion. The market may reassess execution risk, timelines to the planned pivotal study in late 2026, or the open-label design despite strong pharmacokinetics. Historical patterns show that one positive shareholder update coincided with a -6.56% move, suggesting good news has not always translated into near-term price strength.

Interim results indicate NS002 demonstrated significantly faster absorption and higher peak epinephrine levels compared to EpiPen®
NS002 was well-tolerated with no serious adverse events reported, and a pharmacodynamic response comparable to EpiPen®
Full Phase 2 results expected by the end of first quarter of 2026; Pivotal study initiation planned for fourth quarter of 2026
TEL AVIV, Jan. 20, 2026 (GLOBE NEWSWIRE) -- Nasus Pharma Ltd. (NYSE: NSRX) ("Nasus Pharma" or the "Company"), a clinical-stage pharmaceutical company focused on the development of innovative intranasal products to treat emergency medical conditions, today announced positive interim results from its Phase 2 clinical study of NS002, the Company's investigational intranasal epinephrine powder formulation for the treatment of anaphylaxis. The data demonstrated that NS002 achieved faster absorption, higher peak concentrations, and greater early epinephrine exposure compared to intramuscular EpiPen® autoinjector.
The open-label Phase 2 study enrolled 50 healthy adults with a history of allergic rhinitis across two cohorts. At the interim analysis, the first cohort of 25 participants received NS002 or intramuscular EpiPen® with and without a nasal allergic challenge. The second cohort of 25 participants received repeat doses of NS002 or intramuscular EpiPen® with and without a nasal allergic challenge, evaluating real-world scenarios where multiple administrations may be necessary. The final analysis will include results of all 50 subjects who will have received all treatments.
Key Interim Results:
NS002 demonstrated a higher mean peak plasma concentration (“Cmax”) of 655 pg/ml compared to 548 pg/ml for EpiPen®, and achieved peak concentration (“Tmax”) in 10.8 minutes compared to 15 minutes with EpiPen®. Critically,
Repeat administration of NS002 with or without nasal allergic challenge demonstrated consistent pharmacokinetic advantages over EpiPen®. This is a clinically relevant finding, as patients experiencing severe anaphylaxis may require repeat doses to fully resolve symptoms.
The interim analysis includes safety data on all 50 subjects who completed all treatment arms. NS002 was well-tolerated, with no serious adverse events reported. The majority (
The pharmacodynamic response, including changes from baseline in systolic and diastolic blood pressure and pulse rate, was comparable to that of EpiPen® and remained within the normal range.
"We believe these interim results are highly encouraging and reinforce the potential of NS002 as a meaningful advancement in anaphylaxis treatment," said Dr. Michael Blaiss, Clinical Professor of Allergy and Immunology at the Medical College of Georgia at Augusta University and member of Nasus Pharma's Scientific Advisory Board. "The interim data demonstrated that NS002 delivered epinephrine to the bloodstream faster and achieved higher concentrations than an intramuscular autoinjector. In anaphylaxis, outcomes are highly time-dependent, and delays in achieving effective pharmacologic action are associated with increased mortality. These pharmacokinetic advantages, combined with the needle-free administration, could help address the significant compliance challenges we see with current treatments."
"We are extremely pleased with these positive interim results, which we believe further validate NS002's potential as a first-in-class intranasal powder epinephrine product for patients with severe allergies," said Dan Teleman, Chief Executive Officer of Nasus Pharma. "The sustained performance of NS002 across single and repeat dosing scenarios – including under conditions simulating real-world allergic reactions – demonstrates the robustness of our proprietary Nasax® platform technology. We look forward to completing the Phase 2 study and advancing to our pivotal clinical program."
Nasus Pharma expects to complete the Phase 2 study by the end of the first quarter of 2026. The Company plans to initiate its pivotal clinical study in fourth quarter of 2026.
About Nasus Pharma
Nasus Pharma is a clinical-stage pharmaceutical company developing a number of intranasal powder products addressing acute medical conditions in the community. NS002, Nasus’ intranasal powder Epinephrine product candidate is being developed as a needle-free alternative to Epinephrine autoinjectors for patients with anaphylaxis. Intranasal administration is most suitable for those situations in which rapid drug delivery is required and offers needle-free, easy-to-use alternatives. Nasus’ proprietary powder-based intranasal (“PBI”) technology is designed for rapid and reliable drug delivery, leveraging the nasal cavity’s rich vascular network for quick absorption. The PBI formulation uses uniform spherical powder particles for broad dispersion and potentially faster, higher absorption compared to liquid-based nasal products.
