Coinhibitory Pathways in Immunotherapy for Cancer.

Abstract: The immune system is capable of recognizing tumors and eliminates many early malignant cells. However, tumors evolve to evade immune attack, and the tumor microenvironment is immunosuppressive. Immune responses are regulated by a number of immunological checkpoints that promote protective immunity and maintain tolerance. T cell coinhibitory pathways restrict the strength and duration of immune responses, thereby limiting immune-mediated tissue damage, controlling resolution of inflammation, and maintaining tolerance to prevent autoimmunity. Tumors exploit these coinhibitory pathways to evade immune eradication. Blockade of the PD-1 and CTLA-4 checkpoints is proving to be an effective and durable cancer immunotherapy in a subset of patients with a variety of tumor types, and additional combinations are further improving response rates. In this review we discuss the immunoregulatory functions of coinhibitory pathways and their translation to effective immunotherapies for cancer.

Pharmacological Treatment of Coronary Artery Disease With Recombinant Fibroblast Growth Factor-2 Double-Blind, Randomized, Controlled Clinical Trial

Abstract: Background— Single-bolus intracoronary administration of fibroblast growth factor-2 (FGF2) improved symptoms and myocardial function in a phase I, open-label trial in patients with coronary artery disease. We conducted the FGF Initiating RevaScularization Trial (FIRST) to evaluate further the efficacy and safety of recombinant FGF2 (rFGF2). Methods and Results— FIRST is a multicenter, randomized, double-blind, placebo-controlled trial of a single intracoronary infusion of rFGF2 at 0, 0.3, 3, or 30 μg/kg (n=337 patients). Efficacy was evaluated at 90 and 180 days by exercise tolerance test, myocardial nuclear perfusion imaging, Seattle Angina Questionnaire, and Short-Form 36 questionnaire. Exercise tolerance was increased at 90 days in all groups and was not significantly different between placebo and FGF-treated groups. rFGF2 reduced angina symptoms as measured by the angina frequency score of the Seattle Angina Questionnaire (overall P=0.035) and the physical component summary scale of the Short-Form 36 ...

Pamidronate prevents skeletal complications and is effective palliative treatment in women with breast carcinoma and osteolytic bone metastases: long term follow-up of two randomized, placebo-controlled trials.

Abstract: BACKGROUND Pamidronate therapy previously has been shown to reduce skeletal complications effectively for up to 12 months in breast carcinoma patients with bone metastases. The current study data provide further follow-up results regarding the effects of long term (up to 24 months) pamidronate treatment in women with breast carcinoma and osteolytic metastases. METHODS Follow-up results from two prospective, multicenter, randomized, double-blind, placebo-controlled intervention trials conducted at academic and community oncology centers were combined to provide a large data set with which to evaluate the long term efficacy and safety of pamidronate therapy. Seven hundred fifty-four women with Stage IV breast carcinoma and osteolytic metastases were randomized to the 2 treatment arms of the trial. Three patients were excluded from the intent-to-treat population for the analysis. A total of 751 evaluable patients were randomized to receive either a 90-mg intravenous pamidronate infusion (367 patients) or a placebo infusion (384 patients) every 3–4 weeks. The primary outcome measures were skeletal morbidity rate (events/year), proportion of patients developing a skeletal complication, and time to first skeletal complication. RESULTS Of the 367 women receiving pamidronate, 115 (31.3%) completed the trial and 81 (22.1%) discontinued the study due to adverse events. Of the 384 women who received placebo, 100 (26.0%) completed the study and 76 (19.8%) discontinued the study due to adverse events. The skeletal morbidity rate was 2.4 in the pamidronate group and 3.7 in the placebo group (P < 0.001). In the pamidronate group, 186 of the 367 patients (51%) had skeletal complications compared with 246 of the 384 patients in the placebo group (64%) (P < 0.001). The median time to first skeletal complication was 12.7 months in the pamidronate group and 7 months in the placebo group (P < 0.001). Six patients treated with pamidronate discontinued treatment due to drug-related adverse events. Pain and analgesic scores were significantly worse in the placebo group compared with those patients in the pamidronate group. CONCLUSIONS In the current study, monthly infusions of 90 mg of pamidronate as a supplement to antineoplastic therapy were found to be well tolerated and superior to antineoplastic therapy alone in preventing skeletal complications and palliating symptoms for at least 24 months in breast carcinoma patients with osteolytic bone metastases.
