Karyopharm is currently investigating eltanexor in an ongoing open-label Phase 1/2 study as a single-agent or in combination with approved and investigational agents in patients with several types of hematologic and solid tumor cancers (KCP-8602-801; NCT02649790). Previously, Karyopharm reported positive data from an investigator-sponsored Phase 1 study evaluating single-agent eltanexor in patients with hypomethylating agent (HMA)-refractory MDS, where eltanexor demonstrated a 53% overall response rate and median overall survival of 9.9 months. This compares favorably to historical survival of four to six months for HMA-refractory MDS patients.

Approximately 15,000 people are diagnosed with intermediate-to-high risk MDS each year in the U.S.1 HMAs are the current standard of care for newly diagnosed, higher-risk MDS patients. However, only 40-60% of patients respond, with these responses typically lasting less than two years.2 The prognosis in HMA-refractory disease is poor, with a median overall survival of four to six months.3,4 There are currently no approved therapies for HMA- refractory MDS.

"We are pleased to receive the FDA’s orphan drug designation for eltanexor in MDS and believe it reinforces eltanexor’s potential to improve clinical outcomes for patients with HMA-refractory MDS," said Richard Paulson, President and Chief Executive Officer of Karyopharm. "We are focused on advancing our ongoing clinical trials and remain steadfast in our commitment to bringing this new treatment option to patients and their families."

Orphan drug designation by the FDA is granted to promote the development of drugs that target conditions affecting 200,000 or fewer U.S. patients annually and are expected to provide a significant therapeutic advantage over existing treatments. Orphan designation qualifies a company for certain incentives that apply across all stages of drug development, including the potential for seven years of market exclusivity following marketing approval, tax credits on qualified U.S. clinical trials, eligibility for orphan drug grants, and exemption from certain administrative fees.

About Eltanexor

Eltanexor (KPT-8602) is an investigational novel SINE compound that, like selinexor, functions by binding with, and inhibiting, the nuclear export protein, XPO1, leading to the accumulation of tumor suppressor proteins in the cell nucleus. This reinitiates and amplifies their tumor suppressor function and is believed to lead to the selective induction of apoptosis in cancer cells, while largely sparing normal cells.

In preclinical models, eltanexor has a broad therapeutic window with minimal penetration of the blood brain barrier and, therefore, has the potential to serve as another SINE compound for cancer indications. Following oral administration, animals treated with eltanexor show lower percentage of body weight loss and improved food consumption than animals similarly treated with selinexor. This allows more frequent dosing of eltanexor, enabling a longer period of exposure than is possible with selinexor.

Eltanexor is an investigational medicine and has not been approved by the United States Food and Drug Administration or any other regulatory agency.

Preliminary Unaudited Fourth Quarter 2021 and Full Year Revenue

Management expects total revenue for the fourth quarter of 2021 to be more than $10.0 million, up from $8.5 million of total revenue in the fourth quarter of 2020, reflecting growth of at least 17% in total revenue and at least 37% in core business revenue.

MaxCyte’s revenue for the fourth quarter of 2021 was derived from its core business, which is defined as sales or leases of instruments, sales of single-use disposables, and sales of consumables (buffer) to the cell therapy and drug discovery markets.

MaxCyte also generates revenue under Strategic Platform License agreements (SPLs) with cell therapy developers, such as precommercial milestone payments. These revenues are categorized as program-related revenue and are excluded from core business revenue.

Preliminary revenue for the full year ended December 31, 2021 is expected to be more than $33.7 million, up from $26.2 million in full year 2020, reflecting growth of at least 28% in total revenue and at least 36% in core business revenue. Revenue for the full year ended December 31, 2021 includes $2.5 million of program-related revenue, compared to $3.3 million of program-related revenue in 2020.

MaxCyte ended the year with 15 SPLs, including 4 SPLs added during 2021: Nkarta, Inc., Myeloid Therapeutics, Celularity, Inc. and Sana Biotechnology, Inc.

Doug Doerfler, President and CEO of MaxCyte said: "We are proud of our performance in the fourth quarter as well as the full year, which has been a year of key achievements for the company. This includes raising $257.2 million in gross equity proceeds, the completion of an IPO in the United States and commencement of trading in our common stock on the Nasdaq, continuing significant organic growth in our core business, and our ongoing success in signing SPLs with innovative cell therapy developers. We are also excited to confirm that our ExPERT VLx instrument became available for sale at the end of December."

"We remain optimistic about the potential for our SPLs to generate meaningful revenue over the next 12 to 18 months and beyond. Our partners continue to achieve clinical success – particularly in moving their next-generation product candidates into pivotal trials. We also see the potential for several IND filings by our SPL customers for novel ex vivo engineered cell therapies this year. Finally, we continue to benefit from the ongoing investment in the ex vivo engineered cell therapy space. As a result, we believe our SPL pipeline remains as robust and diverse as ever. We look forward to a strong 2022."

MaxCyte’s fourth quarter and full year 2021 financial results presented in this release are preliminary and unaudited and are subject to revision based on the completion of MaxCyte’s normal quarter and year-end process and year-end audit. As a result, these preliminary results may be different from the actual results that will be reflected in MaxCyte’s consolidated financial statements for the quarter and year ended December 31, 2021, which are expected to be released by the end of March 2022.

On January 24, 2022 Deciphera Pharmaceuticals, Inc.

"Patients with GIST in the post-imatinib setting are in need of additional treatment options for their disease, and the results from INTRIGUE demonstrate that ripretinib is an active and well-tolerated agent. Although the INTRIGUE study did not meet its primary endpoint of superiority in progression-free survival versus sunitinib, the efficacy of ripretinib appears comparable to sunitinib in 2nd line patients. In addition, ripretinib had a more favorable safety profile than sunitinib with fewer Grade 3/4 adverse events and patients reported less deterioration in role functioning and several other key patient-reported outcome measures of tolerability," said Dr. Heinrich. "It is important to provide the detailed results of this study to the oncology community to help treating physicians make well-informed decisions on the best treatment options for their patients with advanced GIST."

In patients with GIST who progressed on or were intolerant to imatinib, the efficacy of QINLOCK and sunitinib were comparable, although progression-free survival (PFS) of QINLOCK as determined by independent radiologic review using modified Response Evaluation Criteria in Solid Tumors (RECIST) did not meet the study’s primary endpoint of superiority compared to sunitinib. The statistical analysis plan included a hierarchical testing sequence that included evaluation of patients with a KIT exon 11 primary mutation (Exon 11) and then of the all patient (AP) population. Key highlights from the study presented today include the following:

An international, multicenter study conducted in 122 active sites across 22 countries, 453 patients were randomized to ripretinib (n = 226; Exon 11, n = 163) or sunitinib (n = 227; Exon 11, n = 164).
In patients with a KIT exon 11 primary mutation, ripretinib demonstrated a median PFS (mPFS) of 8.3 months compared to 7.0 months for the sunitinib arm (Hazard Ratio [HR] 0.88, p=0.36). In the AP population (n=453), ripretinib demonstrated an mPFS of 8.0 months compared to 8.3 months for the sunitinib arm (HR 1.05, nominal p value=0.72).
In patients with a KIT exon 11 primary mutation, ripretinib demonstrated an objective response rate (ORR) of 23.9% (n=39 of 163) compared to 14.6% (n=24 of 164) for sunitinib (nominal p value=0.03). In the AP population ripretinib demonstrated an ORR 21.7% (n=49 of 226) compared to 17.6% (n=40 of 227) for sunitinib (nominal p value=0.27).
Ripretinib was generally well tolerated. Fewer patients in the ripretinib arm experienced Grade 3-4 treatment-emergent adverse events compared to sunitinib (41.3% vs 65.6%).
Patients receiving sunitinib were three times more likely to develop Grade 3 hypertension compared to patients receiving ripretinib (26.7% vs. 8.5%) and patients receiving sunitinib were seven times more likely to develop Grade 3 palmar-plantar erythrodysesthesia compared to patients receiving ripretinib (10.0% vs. 1.3%).
Patient reported outcome measures also showed a more favorable tolerability profile for patients receiving ripretinib compared to patients receiving sunitinib. Patients receiving ripretinib experienced less deterioration in their ability to engage in either work or leisure activities during treatment and fewer patients receiving ripretinib experienced moderate to extremely large impact on their lives due to skin toxicity across treatment cycles compared to patients receiving sunitinib.
QINLOCK is approved by the U.S. Food and Drug Administration (FDA) for the treatment of adult patients with advanced GIST who have received prior treatment with three or more kinase inhibitors, including imatinib. The new drug application (NDA) for QINLOCK was based on positive results from the Phase 3 INVICTUS trial in patients with fourth-line and fourth-line plus GIST1. QINLOCK is also approved for the treatment of fourth-line GIST in Australia, Canada, China, the European Union, Hong Kong, Switzerland, Taiwan, and the United Kingdom.

About QINLOCK (ripretinib)

QINLOCK is a switch-control tyrosine kinase inhibitor that was engineered to broadly inhibit KIT and PDGFRA mutated kinases by using a dual mechanism of action that regulates the kinase switch pocket and activation loop. QINLOCK inhibits primary and secondary KIT mutations in exons 9, 11, 13, 14, 17, and 18 involved in GIST, as well as the primary exon 17 D816V mutation2,3. QINLOCK also inhibits primary PDGFRA mutations in exons 12, 14, and 18, including the exon 18 D842V mutation, involved in a subset of GIST2,3.
