Kyverna's KYTX Soars 25.95% on Groundbreaking SPS Trial Success: A New Era for Autoimmune CAR-T?

Summary
• Kyverna Therapeutics (KYTX) surges 25.95% intraday, trading at $11.0585 after announcing landmark SPS trial results
• Miv-cel achieves 46% median improvement in mobility and 100% immunotherapy-free status in 26-patient trial
• FDA BLA submission for SPS expected in 1H 2026, with Regenerative Medicine and Orphan Drug designations secured

Kyverna’s stock erupted in premarket trading following the release of transformative Phase 2 data for miv-cel in stiff person syndrome (SPS). The 25.95% intraday surge—driven by statistically significant clinical outcomes and a well-tolerated safety profile—positions the biotech at a pivotal inflection point. With the stock trading near its 52-week high of $13.67 and a 72.58% turnover rate, market participants are recalibrating expectations for Kyverna’s autoimmune CAR-T pipeline.

SPS Trial Success Ignites Biotech Sector Optimism
Kyverna’s 25.95% intraday rally stems from the release of topline data showing miv-cel’s ability to reverse disability in SPS, a disease with no FDA-approved therapies. The trial demonstrated a 46% median improvement in the 25-foot walk test (p=0.0002), with 81% of patients exceeding a clinically meaningful 20% threshold. All secondary endpoints, including mobility and stiffness indices, showed highly significant benefits. The absence of high-grade cytokine release syndrome (CRS) or neurotoxicity further bolstered investor confidence, positioning miv-cel as a potential first-in-class therapy. The company’s plans to submit a BLA in 1H 2026 and present data at a 2026 medical conference have amplified near-term catalysts.

Biotech Sector Mixed as Kyverna Outperforms
While Kyverna’s stock surged, the broader biotech sector showed mixed momentum. Amgen (AMGN), the sector’s top performer, rose 0.67% intraday, reflecting steady demand for its established therapies. However, Kyverna’s 25.95% move far outpaced peers, driven by its unique positioning in the autoimmune CAR-T space. The absence of direct sector linkage—given Kyverna’s niche focus on B-cell-driven autoimmune diseases—highlights the stock’s idiosyncratic nature, with its rally primarily fueled by SPS trial results rather than broader industry trends.

Options and ETF Plays for Kyverna’s Volatile Momentum
• MACD: 0.379 (bullish divergence), Signal Line: 0.272, Histogram: 0.107 (positive momentum)
• RSI: 67.14 (neutral to overbought), Bollinger Bands: $6.46–$8.79 (price above upper band)
• 200D MA: $4.16 (far below current price), 30D MA: $7.35 (support level)

Kyverna’s technicals suggest a continuation of its bullish trend, with the stock trading near its 52-week high and RSI hovering in overbought territory. The 200-day average remains a distant support, while the 30-day MA at $7.35 could act as a near-term floor. Given the high implied volatility (IV) and liquidity in the options chain, aggressive positioning via call options may offer leveraged exposure to potential follow-through buying.

Backtest Kyverna Stock Performance
The backtest of the Kentucky State University (KYTX) performance following a 26% intraday surge from 2022 to the present reveals a mixed outcome. While the 3-Day and 10-Day win rates are high at 43.14% each, the 30-Day win rate is slightly lower at 42.16%. However, the returns over these periods are negative, with a maximum return of -0.39% over 30 days, indicating that the ETF has struggled to generate positive returns in the long term following the intraday surge.

Kyverna’s SPS Breakthrough: A Catalyst-Driven Bull Case
Kyverna’s 25.95% intraday surge underscores the transformative potential of miv-cel in SPS, a disease with no approved therapies. With the stock trading near its 52-week high and a robust options chain reflecting high implied volatility, the technical and fundamental outlook remains bullish. Investors should monitor the 12.50 resistance level and the 1H 2026 BLA submission as key catalysts. Meanwhile, Amgen’s 0.67% gain highlights the broader biotech sector’s mixed momentum, but Kyverna’s unique positioning in autoimmune CAR-T suggests its rally is driven by idiosyncratic, not sector-wide, factors. Watch for a breakout above $12.50 or a pullback to the 30-day MA at $7.35 for entry opportunities.
