Clinical / Regulatory Status in China and Key Data Summaries for NXP100 and NXP200

NXP100 (HSK39297)

Paroxysmal Nocturnal Hemoglobinuria (PNH)

Two MAAs for NXP100 have been submitted to the Chinese National Medical Products Administration (NMPA) and are currently under review:

The first MAA is based on positive data from a completed randomized, open-label, active comparator-controlled, Phase 3 study (clinicaltrials.gov NCT06799546). In this study, 73 adult Chinese treatment naïve PNH patients were randomized 1:1 to receive either NXP100 or Soliris® (eculizumab), a Complement C5 inhibitor, for a 24-week treatment period. The primary efficacy endpoint was to evaluate the proportion of patients achieving hemoglobin (Hgb) levels ≥ 12 g/dL on at least three out of four measurements between Week 18 and Week 24 in the absence of red blood cell (RBC) transfusions. Treatment with NXP100 was superior to treatment with eculizumab in the primary and all key secondary endpoints (overall increase in Hgb levels, reducing the requirement for RBC transfusions, and avoiding extravascular hemolysis).

Parameter	NXP100 (n=37)	Eculizumab (N=36)
Primary Endpoint
Proportion of participants achieving Hgb levels ≥12 g/dL without RBC transfusion % (95% CI)	59.5 (43.2, 75.7)	8.3 (2.8, 19.4)
p-Value	< 0.001

The second MAA is based on positive data from a completed single-arm, Phase 3 study (clinicaltrials.gov NCT07052838). In this study, 36 adult Chinese patients with PNH and persistent anemia who failed treatment with C5 inhibitors were treated with NXP100 for a 24-week treatment period. The primary efficacy endpoint was to evaluate the proportion of patients achieving Hgb levels ≥ 12 g/dL on at least three out of four measurements between Week 18 and Week 24 in the absence of RBC transfusions from Week 2, with efficacy prospectively defined as having the lower bound of the 95% CI for the response rate exceeding 20%. The study met the primary and all key secondary endpoints (overall increase in Hgb levels, reducing the requirement for RBC transfusions, and avoiding extravascular hemolysis).

Parameter	NXP100 (n=36)
Primary Endpoint
Proportion of participants achieving Hgb levels ≥12 g/dL without RBC transfusion % (95% CI)	52.8 (35.5, 69.6)

Immunoglobulin A Nephropathy (IgAN)

In China, a Phase 3 clinical trial (NCT07390123) is ongoing in IgAN following positive data from a randomized, placebo-controlled Phase 2 (NCT06670352). In the Phase 2 study, the efficacy of treatment with NXP100 was investigated in a 24-week treatment period versus placebo with efficacy defined as reduction in the ratio of 24-hour urine protein to creatinine (24h-UPCR) compared to baseline after 12 weeks of treatment. Treatment with NXP100 resulted in clinically meaningful reduction in 24h-UPCR after 4 weeks, and the magnitude of the treatment effect increased over time. NXP100 also demonstrated excellent estimated Glomerular Filtration Rate (eGFR) control (a secondary endpoint) vs placebo in the study.

Parameter	Week 4	Week 12 (Primary Endpoint)	Week 24
Reduction in 24h-UPCR relative to baseline vs. placebo NXP100 N=24 Placebo N=21	-33%	-45.3%	-57.7%

In addition, a Phase 2 of NXP100 for the treatment of LN is also ongoing in China.

NXP100 Competitive Landscape and Market Analysis

The PNH market size is expected to be >$5.0BN in 2026 with the injectable C5 inhibitor drugs Soliris® and Ultomiris®, marketed by Alexion/AstraZeneca Rare Disease, projected to be approximately $4.5BN of the total market. The PNH market is expected to more than double to >$10BN within 8 years. Soliris and Ultomiris were the centerpiece of Astra Zeneca’s acquisition of Alexion in 2021 for $39BN.
Fabhalta (iptacopan, launched in 2024), marketed by Novartis, is the only FDA approved Complement Factor B inhibitor with approvals in PNH, IgAN and C3G.
- Fabhalta®is administered orally, twice per day, vs NXP100 which is administered once a day.
- Fabhalta® is currently also being investigated in several clinical trials, including LN, Myasthenia Gravis (MG) and dry Age-related Macular Degeneration (dAMD).
- Fabhalta® peak annual revenue in the currently approved indications is projected by analysts to reach $5B to $10B. The PNH and IgAN markets are estimated to reach >$20BN combined within the next 10 years.
In randomized Phase 3 clinical trials in patients with PNH, treatment with either NXP100 or Fabhalta® was superior to treatment with C5 inhibitors, with comparable treatment effect for NXP100 and Fabhalta across studies, positioning CFBis to potentially dominate the PNH market over time.
In IgAN, the Phase 2 data suggests that NXP100 has the potential to be comparable to the best injectable APRIL/BAFF inhibitors on the key renal function endpoints, including 24-hour UPCR and eGFR control.
In cross study comparisons, the observed safety profile of NXP100 appears to be similar to that of Fabhalta®.

NXP200 (HSK42360)

Overview, Competitive Landscape and Market Analysis

BRAF is a validated therapeutic target in oncology with first generation drugs such as Tafinlar® (dabrafenib, marketed by Novartis) and Braftovi® (encorafenib, marketed by Pfizer) approved in multiple indications. These first-generation BRAF inhibitors effectively inhibit the V600-mutated BRAF, which results in initial antitumor activity, but also leads to paradoxical activation through stimulation of the MAPK signaling pathway, causing treatment resistance and development of secondary malignancies, primarily skin squamous cancer and other skin-related side effects. The current solution to the paradoxical activation problem is concomitant administration of MEK inhibitors, but while the skin side effects are reduced, they are not eliminated and acquired resistance still emerges. In addition, Class II and III BRAF mutations are not inhibited by first generation BRAF inhibitors. Designed to overcome this paradoxical activation, paradox-breaking BRAF inhibitors represent the next generation approach to targeting BRAF. There are currently several paradox breakers BRAF inhibitors in clinical development, none are FDA approved.

Available data to date suggests that NXP200 is the only paradox-breaker BRAF inhibitor that has consistently demonstrated single agent activity in CNS tumors but, importantly, also in additional solid tumor types that harbor BRAF mutations. In a completed dose escalation study of NXP200 as monotherapy in heavily pre-treated patients with BRAF V600-mutated solid tumors, including ones previously treated with BRAF/MEK inhibitors, NXP200 demonstrated an acceptable safety profile and single-agent durable clinical activity in various tumor types, including a >40% response rate in low- and high-grade adult glioma, including one Complete Response. Durable responses were also demonstrated in non-small cell lung cancer (NSCLC), colorectal and papillary thyroid cancers.

In this dose escalation program, treatment with a first-generation, free base form of NXP200 was used. A second-generation salt form of NXP200 was recently developed to enhance the pharmacokinetic (PK) profile of NXP200, and early data indeed demonstrate a marked improved PK and greater single agent clinical activity. Thus, with favorable pharmacology, promising early clinical data and possible applicability across V600, Class I and Class II-altered solid tumors, NXP200 could emerge as a best-in-class next-generation BRAF inhibitor. NXP200 is currently in a Phase 1b study in China.

The combined annual revenue for the first-generation BRAF inhibitors, typically administered in combination with a MEK inhibitor to overcome paradoxical activation, is estimated at approximately $4BN.

Of note, in April 2026, Servier acquired Day One Biopharmaceuticals for $2.5BN with its only FDA approved drug, Ojemda (tovorafenib), a first generation BRAF inhibitor which is indicated for the treatment of relapsed or refractory pediatric in BRAF-altered low-grade glioma. With projected 2026 sales of $225-250M, sales of Ojemda represent only 6% of the current BRAF market.
