| Item 7.01. | Regulation FD Disclosure. |
On April 8, 2022, Rubius Therapeutics, Inc. (the “Company”) issued a press release titled “Rubius Therapeutics Reports Updated Clinical Data at AACR from the Ongoing Monotherapy Phase 1 Arm of the Phase 1/2 Clinical Trial of RTX-240 in Advanced Solid Tumors Demonstrating Single-Agent Activity and Favorable Tolerability.” A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.
The information under this Item 7.01, including Exhibit 99.1 hereto, is being furnished herewith and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as expressly set forth by specific reference in such filing.
| Item 8.01. | Other Events. |
The Company today presented updated clinical data from the ongoing monotherapy Phase 1 arm of the Phase 1/2 clinical trial of RTX-240 in patients with advanced solid tumors at the American Association for Cancer Research Annual Meeting.
Updated Data from the Phase 1 Trial of RTX-240 in Patients with Advanced Solid Tumors
Nine dose cohorts (n=34) were completed in the monotherapy solid tumor arm of the trial at the time of the data cutoff on March 4, 2022, with 34 patients evaluable for safety (primary outcome measure) and 27 patients evaluable for efficacy (secondary outcome measure). Enrollment continues in the 5e10 Q3W dose cohort.
As of the cutoff date, disease control was observed in 10 patients (1 partial response ("PR"), 2 unconfirmed PRs ("uPRs") and 7 with stable disease ("SD")), 9 of whom had experienced disease progression on prior anti-PD-1/anti-PD-L1 therapy.
There were three best responses of PR in non-small cell lung cancer ("NSCLC"), anal cancer and uveal melanoma patients:
| · | A uPR with 41% decrease of all target lesions and a notable decrease of an external protruding chest wall mass in a patient with NSCLC whose disease had progressed on prior anti-PD-L1 therapy; |
| · | A confirmed PR with a 54% reduction in the target lesions in a patient with metastatic anal cancer whose disease had progressed on anti-PD-L1 therapy; and |
| · | An uPR with 100% decrease of the target hepatic lesion and resolution of multiple non-target hepatic lesions in a patient with metastatic uveal melanoma whose disease had progressed on anti-PD-1 therapy. |
Stable disease was observed in 5 patients, including 3 with metastatic NSCLC and 2 with renal cell carcinoma ("RCC") across the 3e10 cohorts, supporting the Company’s decision to expand the Phase 1 arm of RTX-240 plus pembrolizumab to NSCLC and RCC patients. One patient each with NSCLC and RCC remained on monotherapy treatment with SD greater than 6 months as of the cutoff date.
As of the cutoff date, RTX-240 has been shown to have been generally well tolerated with no treatment-related or investigator-identified immune-related Grade 3/4 adverse events ("AEs") and no dose-limiting toxicities ("DLTs").
C:
Based on the totality of clinical, tolerability and pharmacodynamic data, a recommended monotherapy Phase 2 dose of 5e10 cells administered every 3 weeks was selected. This dose will be further explored in the combination expansion cohort of NSCLC and RCC patients.
Final Phase 1 Clinical Results in Relapsed/Refractory Acute Myeloid Leukemia ("AML")
The Company also announced final clinical results from the Phase 1 arm of monotherapy RTX-240 in relapsed/refractory AML. As of the cutoff date of March 4, 2022, seventeen patients were enrolled across 4 dose levels. No DLTs were observed and there were 3 treatment-related Grade 3/4 adverse events. There were no investigator-reported immune-related AEs. Five patients had SD greater than 3 months, and 1 patient had a significant blast count reduction (53% to 6%).
