SL-701

Property	Information
Drug Name	SL-701 (Immunotherapy Vaccine)
FDA Approval	In clinical trials; not yet FDA-approved
Used for	Relapsed or refractory Glioblastoma Multiforme (GBM)
Clinical Trial Phase	Phase II
Clinical Trial Explanation	Not specified
Common Side Effects	Fatigue, injection site reaction, erythema, and pain were the most common treatment-related adverse events. No grade 4/5 adverse events reported, indicating a manageable safety profile.
OS without	Historical controls suggest a median overall survival of 20-35% at 12 months for similar populations.
OS with	Stage 1 median overall survival was 11.0 months with a 12-month OS rate of 44%. Stage 2 showed a median OS of 11.7 months with a 12-month OS rate of 50%, suggesting an improvement over historical data.
PFS without	Not specified
PFS with	Data on progression-free survival specifically for SL-701 is under investigation; significant antitumor activity has been noted.
Usefulness Rating	4
Usefulness Explanation	SL-701 shows promise in extending overall survival and inducing long-term survival in a subset of patients, particularly those with target-specific CD8+ T cell responses. The vaccine's ability to elicit specific immune responses against GBM antigens underscores its potential as a novel treatment strategy.Property "Has Usefulness Explanation" (as page type) with input value "SL-701 shows promise in extending overall survival and inducing long-term survival in a subset of patients, particularly those with target-specific CD8+ T cell responses.

Toxicity Level	2
Toxicity Explanation	The vaccine's safety profile is characterized by the absence of severe adverse events, with only mild to moderate reactions observed, making it a potentially safer option for GBM treatment.

From Ben Williams Book: A similar approach has been used by Dr. Hideho Okada and colleagues at the University of Pittsburgh. In a pilot study using this approach with patients with recurrent tumors (162) several major tumor responses were observed. Median survival for the 13 GBM patients in the trial was 12 months, with several of the patients still progression-free at the time of the report. A later version of this therapy, called SL-701, consists of three shortened peptides corresponding to glioma-associated antigens and is now being tested in a phase I/II trial for HLA-A2 positive recurrent glioblastoma.Property "Has original text" (as page type) with input value "A similar approach has been used by Dr. Hideho Okada and colleagues at the University</br>of Pittsburgh.
